自定义KingAdmin

　　通过admin样式自己做KingAdmin

提前需知道的model操作

  1. # 获取app名
  2. >>> models.Customer._meta.app_label
  3. 'repository'
  4.  
  5. # 获取数据表名
  6. >>> models.Customer._meta.verbose_name     # verbose_name
  7. 'customer'
  8. >>> models.Customer._meta.verbose_name_plural
  9. '客户表'
  10. >>> models.Customer._meta.model_name      #表名小写
  11. 'customer'    
  12.  
  13. # 获取数据表字段、是否为choices类型
  14. >>> models.Customer._meta.get_field('status')
  15. <django.db.models.fields.SmallIntegerField: status>    #字段
  16. >>> models.Customer._meta.get_field('status').choices   #choices字段
  17. ((0, '已报名'), (1, '未报名'), (2, '已退学'), (3, '其他'))
  18. >>> models.Customer._meta.get_field('id').choices     # 普通字段
  19. []
  20. >>> models.Customer._meta.get_field('consultant').choices  #外键字段
  21. []

1、在Django项目中创建kingadmin

2、app_config.py获取已注册以及存在kingadmin.py的App

  1. from django import conf
  2.  
  3. for app in conf.settings.INSTALLED_APPS:
  4.     try:
  5.         __import__('%s.kingadmin'%app)
  6.     except ImportError as e:
  7.         print('%s has no model kingadmin'%app)

3、views.py加载自定义的app_config.py文件

  1. from django.shortcuts import render
  2.  
  3. from kingadmin import app_config  # 加载app_config
  4. from kingadmin.base_admin import site
  5.  
  6. def app_index(request):
  7.  
  8.     print(id(site),site.registered_sites)
  9.     return render(request, 'kingadmin/app_index.html',{'site':site})
  10.  
  11. def table_data_list(request,app_name,model_name):
  12.     admin_obj = site.registered_sites[app_name][model_name]
  13.     admin_obj.querysets =  admin_obj.model.objects.all()
  14.  
  15.     return render(request,"kingadmin/table_data_list.html",locals())    # locals 传入局部变量

4、base_admin.py定义注册的model（核心）

  1. class AdminRegisterException(Exception):
  2.     def __init__(self,msg):
  3.         self.message = msg
  4.  
  5. class BaseAdmin(object):
  6.     list_display = ()
  7.     list_filter = ()
  8.     search_fields = ()
  9.     list_editable = ()
  10.  
  11. class Adminsite(object):
  12.     def __init__(self):
  13.         self.registered_sites = {}
  14.  
  15.     def register(self,model,admin_class=None):
  16.         '''
  17.         :param model: <class 'crm.models.Course'>
  18.         :param admin_class:
  19.         :return:
  20.         '''
  21.         app_name = model._meta.app_label       # python manage.py shell
  22.         model_name = model._meta.model_name     # dir(<class 'crm.models.Course'>) 查看具有的方法
  23.         if not admin_class:
  24.             admin_class = BaseAdmin
  25.  
  26.         if app_name not in self.registered_sites:
  27.             self.registered_sites[app_name]={}
  28.  
  29.         if model_name in self.registered_sites[app_name]:
  30.             raise AdminRegisterException("app [%s] model [%s] has already registered!" % (app_name, model_name))
  31.  
  32.         # admin_obj = admin_class()
  33.         admin_obj = admin_class()
  34.         admin_obj.model = model
  35.         self.registered_sites[app_name][model_name] = admin_obj
  36.  
  37. site = Adminsite()
  38.  
  39. # site = {
  40. #     'crm':{
  41. #         'customers':CustomerAdmin,
  42. #         'customerfollowup':CustomerFollowUPAdmin,
  43. #     }
  44. # }

　

5、crm目录下创建kingadmin.py进行models注册

  1. from kingadmin.base_admin import site,BaseAdmin
  2. from crm import  models
  3.  
  4. class CustomerAdmin(BaseAdmin):
  5.     list_display = ('id','name','qq','consultant','source','consult_content','status','data')
  6.     list_filter = ('source','status','consultant')
  7.     search_fields = ('qq','name')
  8.     list_editable = ('status',)
  9.  
  10. site.register(models.Customer,CustomerAdmin)
  11. site.register(models.FollowUpRecord)
  12. site.register(models.Enrollment)
  1. from django.db import models
  2. from django.contrib.auth.models import  User
  3. # Create your models here.
  4.  
  5. class Customer(models.Model):
  6.     '''潜在客户信息'''
  7.     name = models.CharField(max_length=32,blank=True,null=True)

  10.     age = models.PositiveIntegerField(blank=True,null=True)
  11.     gender = models.PositiveIntegerField(choices=((0,'Female'),(1,'Male')),blank=True,null=True)
  12.     phone = models.PositiveIntegerField(blank=True,null=True)  #正整数

  19.         (5,'转介绍'),
  20.         (6,'其他'),
  21.     )
  22.     source = models.SmallIntegerField(choices=source_choices) # get_source_display 显示具体内容
  23.     referral_from = models.ForeignKey('Customer',related_name='my_referrals',blank=True,null=True) # 自关联，字段可写slef，必须写related_name
  24.     consult_courses = models.ManyToManyField(to='Course')
  25.     status_choices = (
  26.         (0,'已报名'),(1,'未报名'),(2,'已退学'),(3,'其他')

  38.  
  39. class Enrollment(models.Model):

7、创建templatetags目录下kingadmin_tags.py文件 自定义模板方法

  1. from django import template
  2. from django.utils.safestring import mark_safe
  3.  
  4. register = template.Library()
  5.  
  6. @register.simple_tag
  7. def get_model_verbose_name(model_obj):
  8.  
  9.     model_name = model_obj._meta.verbose_name_plural
  10.  
  11.     if not model_name:
  12.         model_name = model_obj._meta.model_name
  13.  
  14.     return model_name
  15.  
  16. @register.simple_tag
  17. def get_model_name(model_obj):
  18.  
  19.     return model_obj._meta.model_name
  20.  
  21. @register.simple_tag
  22. def get_app_name(model_obj):
  23.  
  24.     return model_obj._meta.app_label
  25.  
  26. @register.simple_tag
  27. def build_table_row(admin_obj,obj):
  28.  
  29.     row_ele = ""
  30.  
  31.     for column in admin_obj.list_display:
  32.         column_obj = obj._meta.get_field(column)
  33.         if column_obj.choices:

  38.  
  39.         td_ele = '''<td>%s</td>''' % column_data
  40.         row_ele += td_ele
  41.  
  42.     return mark_safe(row_ele)

初步效果：　　

模仿Admin做检索

1、修改views.py

  1. from django.shortcuts import render
  2.  
  3. from kingadmin import app_config  # 加载app_config
  4. from kingadmin.base_admin import site
  5.  
  6. def app_index(request):
  7.  
  8.     print(id(site),site.registered_sites)
  9.     return render(request, 'kingadmin/app_index.html',{'site':site})
  10.  
  11. def filter_querysets(request,model):    #过滤
  12.     condtions = {}
  13.     for k,v in request.GET.items():
  14.         if v :
  15.             condtions[k] = v
  16.     querysets =model.objects.filter(**condtions)
  17.  
  18.     return querysets,condtions
  19.  
  20. def table_data_list(request,app_name,model_name):   #重新改造函数，加上过滤条件
  21.     # print(request.GET)
  22.     admin_obj = site.registered_sites[app_name][model_name]
  23.     model = admin_obj.model
  24.     admin_obj.querysets,admin_obj.condtions =   filter_querysets(request,model)
  25.  
  26.     print(admin_obj.condtions)
  27.     return render(request,"kingadmin/table_data_list.html",locals())    # locals 传入局部变量

2、新增自定义simple_tag

  1. @register.simple_tag
  2. def get_filter_field(filter_column,admin_obj):
  3.     field_obj = admin_obj.model._meta.get_field(filter_column)
  4.  
  5.     selected  = None
  6.     condtions = admin_obj.condtions
  7.     if filter_column in condtions:
  8.         selected = condtions[filter_column]
  9.  
  10.     select_ele = """<select name= "%s">""" % filter_column
  11.     for choice in field_obj.get_choices():
  12.         if selected and selected == str(choice[0]):
  13.             option_ele = """<option value="%s" selected> %s </option> """ % choice
  14.         else:
  15.             option_ele = """<option value="%s"> %s </option> """%choice
  16.         select_ele +=option_ele
  17.     select_ele += """</select>"""
  18.  
  19.     return mark_safe(select_ele)

3、修改table_data_list.html

  1. {% extends 'kingadmin/index.html' %}
  2. {% load kingadmin_tags %}
  3.  
  4. {% block right-container-content %}
  5.  
  6.     <h4>{% get_model_verbose_name admin_obj.model  %}</h4>
  7. {#    {{ admin_obj.list_filter }}#}
  8.     {% if admin_obj.list_filter %}
  9.         <div class="row">
  10.             <form>
  11.                 {% for filter_column in admin_obj.list_filter %}
  12.                     <div class="col-lg-3">
  13.                     {{ filter_column }}:{% get_filter_field filter_column admin_obj %}
  14.                     </div>
  15.                 {% endfor %}
  16.                 <input type="submit" class="btn btn-success" value="过滤">
  17.             </form>
  18.         </div>
  19.     {% endif %}
  20.     <table class="table table-hover">
  21.       <thead>
  22.         <tr>
  23.             {% for column in admin_obj.list_display %}
  24.                 <th>{{ column }}</th>
  25.             {% endfor %}
  26.         </tr>
  27.       </thead>
  28.       <tbody>
  29.  
  30.         {% for obj in admin_obj.querysets %}
  31.             <tr>
  32.                 {% build_table_row  admin_obj obj  %}
  33.  
  34.             </tr>
  35.         {% endfor %}
  36.       </tbody>
  37.     </table>
  38.  
  39. {% endblock %}

利用Django自带分页

1、Paginantor官方源码示例-》跳转

  1. >>> from django.core.paginator import Paginator
  2. >>> objects = ['john', 'paul', 'george', 'ringo']
  3. >>> p = Paginator(objects, 2)
  4.  
  5. >>> p.count
  6. 4
  7. >>> p.num_pages
  8. 2
  9. >>> type(p.page_range)  # `<type 'rangeiterator'>` in Python 2.
  10. <class 'range_iterator'>
  11. >>> p.page_range
  12. range(1, 3)
  13.  
  14. >>> page1 = p.page(1)
  15. >>> page1
  16. <Page 1 of 2>
  17. >>> page1.object_list
  18. ['john', 'paul']
  19.  
  20. >>> page2 = p.page(2)
  21. >>> page2.object_list
  22. ['george', 'ringo']
  23. >>> page2.has_next()
  24. False
  25. >>> page2.has_previous()
  26. True
  27. >>> page2.has_other_pages()
  28. True
  29. >>> page2.next_page_number()
  30. Traceback (most recent call last):
  31. ...
  32. EmptyPage: That page contains no results
  33. >>> page2.previous_page_number()
  34. 1
  35. >>> page2.start_index() # The 1-based index of the first item on this page
  36. 3
  37. >>> page2.end_index() # The 1-based index of the last item on this page
  38. 4
  39.  
  40. >>> p.page(0)
  41. Traceback (most recent call last):
  42. ...
  43. EmptyPage: That page number is less than 1
  44. >>> p.page(3)
  45. Traceback (most recent call last):
  46. ...
  47. EmptyPage: That page contains no results

基本使用方法

  1. from django.core.paginator import Paginator, EmptyPage, PageNotAnInteger
  2. from django.shortcuts import render
  3.  
  4. def listing(request):
  5.     contact_list = Contacts.objects.all()
  6.     paginator = Paginator(contact_list, 25) # Show 25 contacts per page
  7.  
  8.     page = request.GET.get('page')
  9.     try:
  10.         contacts = paginator.page(page)
  11.     except PageNotAnInteger:
  12.         # If page is not an integer, deliver first page.
  13.         contacts = paginator.page(1)
  14.     except EmptyPage:
  15.         # If page is out of range (e.g. 9999), deliver last page of results.
  16.         contacts = paginator.page(paginator.num_pages)
  17.  
  18.     return render(request, 'list.html', {'contacts': contacts})

后端处理

  1. {% for contact in contacts %}
  2.     {# Each "contact" is a Contact model object. #}
  3.     {{ contact.full_name|upper }}<br />
  4.     ...
  5. {% endfor %}
  6.  
  7. <div class="pagination">
  8.     <span class="step-links">
  9.         {% if contacts.has_previous %}
  10.             <a href="?page={{ contacts.previous_page_number }}">previous</a>
  11.         {% endif %}
  12.  
  13.         <span class="current">
  14.             Page {{ contacts.number }} of {{ contacts.paginator.num_pages }}.
  15.         </span>
  16.  
  17.         {% if contacts.has_next %}
  18.             <a href="?page={{ contacts.next_page_number }}">next</a>
  19.         {% endif %}
  20.     </span>
  21. </div>

前端展示

2、添加分页全局变量kingadmin.py

  1. class CustomerAdmin(BaseAdmin):
  2.     list_display = ('id','name','qq','consultant','source','consult_content','status','data')
  3.     list_filter = ('source','status','consultant')
  4.     search_fields = ('qq','name')
  5.     list_editable = ('status',)
  6.     list_per_page = 2

　

3、处理函数views.py

  1. def filter_querysets(request,model):    #过滤
  2.     condtions = {}
  3.     for k,v in request.GET.items():
  4.         if v and k !='page':
  5.             condtions[k] = v
  6.     querysets =model.objects.filter(**condtions)
  7.  
  8.     return querysets,condtions
  9.  
  10. from django.core.paginator import Paginator, EmptyPage, PageNotAnInteger
  11. from django.shortcuts import render
  12.  
  13. def listing(request,admin_obj):
  14.  
  15.     paginator = Paginator(admin_obj.querysets, admin_obj.list_per_page) # Show 25 contacts per page
  16.     page = request.GET.get('page')
  17.     try:
  18.         contacts = paginator.page(page)
  19.     except PageNotAnInteger:
  20.         # If page is not an integer, deliver first page.
  21.         contacts = paginator.page(1)
  22.     except EmptyPage:
  23.         # If page is out of range (e.g. 9999), deliver last page of results.
  24.         contacts = paginator.page(paginator.num_pages)
  25.  
  26.     return contacts
  27.  
  28. def table_data_list(request,app_name,model_name):   #重新改造函数，加上过滤条件
  29.     # print(request.GET)
  30.     admin_obj = site.registered_sites[app_name][model_name]
  31.     model = admin_obj.model
  32.     admin_obj.querysets,admin_obj.condtions =   filter_querysets(request,model)
  33.     print('before',admin_obj.querysets)
  34.     admin_obj.querysets = listing(request,admin_obj)
  35.     print('after',admin_obj.querysets)
  36.  
  37.     return render(request,"kingadmin/table_data_list.html",locals())    # locals 传入局部变量

　　

4、kingadmin_tags.py

  1. @register.simple_tag()
  2. def generate_filter_url(admin_obj):
  3.     url = ""
  4.     for k,v in admin_obj.condtions.items():
  5.         url += "&%s=%s"%(k,v)
  6.  
  7.     return url

5、table_data_list.html

  1. tfoot>
  2.         <nav aria-label="...">
  3.           <ul class="pagination">
  4.             <li class="disabled"><a href="#" aria-label="Previous"><span aria-hidden="true">«</span></a></li>
  5.               {% for page in admin_obj.querysets.paginator.page_range %}

过滤、排序、分页组合

1、在原views.py上新增：

  1. # 添加排序
  2. def get_orderby(request,querysets):         #排序
  3.     orderby_fieid = request.GET.get('o')
  4.     if orderby_fieid:
  5.         querys_res = querysets.order_by(orderby_fieid)
  6.     else:
  7.         querys_res = querysets
  8.  
  9.     return querys_res
  10.  
  11. # 过滤修改
  12. def filter_querysets(request,model):    #过滤
  13.     condtions = {}
  14.     except_list = ["page",'o']
  15.     for k,v in request.GET.items():
  16.         if k in except_list:continue
  17.         if v:
  18.             condtions[k] = v
  19.     querysets =model.objects.filter(**condtions)
  20.  
  21.     return querysets,condtions
  22.  
  23. # 分页添加
  24. def listing(request,admin_obj):
  25.     querys_res = get_orderby(request, admin_obj.querysets)

　　

2、自定义simple_tag

  1. @register.simple_tag()
  2. def generate_filter_url(admin_obj,request=None):
  3.     url = ""
  4.     if request:
  5.         if request.GET.get('o'):
  6.             url += "&o=%s" % request.GET.get('o')
  7.     for k,v in admin_obj.condtions.items():
  8.         url += "&%s=%s"%(k,v)
  9.  
  10.     return url
  11.  
  12. @register.simple_tag
  13. def get_orderby_key(request,column):
  14.     current_order_by_key = request.GET.get('o')
  15.     if current_order_by_key:
  16.         if current_order_by_key == column:
  17.            if column.startswith('-'):
  18.                column.strip("-")
  19.            else:
  20.                column = "-%s"%column
  21.         return column
  22.     else:
  23.         return column
  24.  
  25. @register.simple_tag
  26. def display_order_by_icon(request,column):
  27.     current_order_by_key = request.GET.get('o')
  28.     if current_order_by_key:
  29.         if current_order_by_key.strip('-') == column:
  30.             if current_order_by_key.startswith('-'):
  31.                 icons = '''<span class="glyphicon glyphicon-arrow-up" aria-hidden="true"></span>'''
  32.             else:
  33.                 icons = '''<span class="glyphicon glyphicon-arrow-down" aria-hidden="true"></span>'''
  34.  
  35.             return mark_safe(icons)
  36.  
  37.     return ' '

　　

3、html前端页面

  1. // 过滤时添加排序
  2. <form>
  3.     {% for filter_column in admin_obj.list_filter %}
  4.         <div class="col-lg-3">
  5.         {{ filter_column }}:{% get_filter_field filter_column admin_obj %}
  6.         </div>
  7.     {% endfor %}
  8.     <input type="submit" class="btn btn-success" value="过滤">
  9.     <input type="hidden" name="o" value="{{ request.GET.o }}"> //过滤时加上排序
  10. </form>
  11.  
  12. // 排序时加上过滤
  13. {% for column in admin_obj.list_display %}
  14.     <th>
  15.         // 排序时加上过滤
  16.         <a href="?o={% get_orderby_key request column %}{% generate_filter_url admin_obj %}"> {{ column }}</a>
  17.         {% display_order_by_icon request column %}
  18.     </th>
  19. {% endfor %}
  20.  
  21. // 分页时加上过滤和排序
  22. {% for page in admin_obj.querysets.paginator.page_range %}
  23.   {% if page ==  admin_obj.querysets.number  %}
  24.         <li class="active">
  25.   {% else %}
  26.         <li >
  27.   {% endif %}
  28.             // 分页时加上排序和过滤
  29.             <a href="?page={{ page }}{% generate_filter_url admin_obj request%}">{{ page }} <span class="sr-only">(current)</span></a>
  30.         </li>
  31. {% endfor %}

点击过滤或排序时页面恢复到第一页

搜索

1、views.py处理文件

  1. # 添加搜索函数 注意顺序
  2.  
  3. def get_search(request,admin_obj):
  4.     search_content = request.GET.get('q')
  5.     condition = Q()
  6.     condition.connector = 'OR'
  7.     if search_content:
  8.         for column in  admin_obj.search_fields:
  9.             condition.children.append(("%s__contains"%column,search_content))
  10.  
  11.         querysets = admin_obj.querysets.filter(condition)
  12.     else:
  13.         querysets = admin_obj.querysets
  14.     return querysets
  15.  
  16. def table_data_list(request,app_name,model_name):   #重新改造函数，加上过滤条件
  17.  
  18.     admin_obj = site.registered_sites[app_name][model_name]
  19.     model = admin_obj.model
  20.  
  21.     admin_obj.querysets,admin_obj.condtions =   filter_querysets(request,model) #加过滤条件
  22.  
  23.     admin_obj.querysets = get_search(request,admin_obj) # 搜索
  24.  
  25.     admin_obj.querysets = listing(request,admin_obj)        #分页
  26.  
  27.     return render(request,"kingadmin/table_data_list.html",locals())    # locals 传入局部变量

2、自定义simple_tag

  1. @register.simple_tag()
  2. def generate_filter_search(request):
  3.     search_content = request.GET.get('q')
  4.     url = ""
  5.     if search_content:
  6.         url = "&q=%s"%search_content
  7.  
  8.     return url

　

3、前端html页面

  1.  过滤时的from
  2. <form>
  3.     {% for filter_column in admin_obj.list_filter %}
  4.         <div class="col-lg-3">
  5.         {{ filter_column }}:{% get_filter_field filter_column admin_obj %}
  6.         </div>
  7.     {% endfor %}

  12.     <input type="text" name="q" value="{{ request.GET.q }}">
  13. </form>
  14.  
  15. 排序
  16. {% for column in admin_obj.list_display %}
  17.     <th>
  18. {#                    // 排序时加上过滤#}

添加action动作

1、kingadmin.py

  1. class CustomerAdmin(BaseAdmin):
  2.     list_display = ('id','name','qq','consultant','source','consult_content','status','data')
  3.     list_filter = ('source','status','consultant')
  4.     search_fields = ('qq','name')
  5.     list_editable = ('status',)
  6.     readonly_fields = ('name',)
  7.     list_per_page = 5
  8.     actions = ["change_status", ]
  9.  
  10.     def change_status(self, request, querysets):
  11.         print("changeing status", querysets)
  12.         querysets.update(status=1)
  13.  
  14.     change_status.short_description = "改变报名状态"
  15.  
  16. class EnrollmentAdmin(BaseAdmin):
  17.     list_display = ('customer','class_grade','enrollment_date')
  18.  
  19. site.register(models.Customer,CustomerAdmin)
  20. site.register(models.FollowUpRecord)
  21. site.register(models.Enrollment,EnrollmentAdmin)

2、views.py处理函数

  1. def table_data_list(request,app_name,model_name):   #重新改造函数，加上过滤条件
  2.     admin_obj = site.registered_sites[app_name][model_name]
  3.  
  4.     if request.method == "POST":
  5.  
  6.         action = request.POST.get("action_select")
  7.         selected_ids = request.POST.get("selected_ids")
  8.         selected_ids = json.loads(selected_ids)
  9.         print("action:",selected_ids,action)
  10.         selected_objs = admin_obj.model.objects.filter(id__in=selected_ids)
  11.  
  12.         action_func = getattr(admin_obj,action)
  13.         action_func(request,selected_objs)
  14.  
  15.     model = admin_obj.model
  16.  
  17.     admin_obj.querysets,admin_obj.condtions =   filter_querysets(request,model) #加过滤条件
  18.  
  19.     admin_obj.querysets = get_search(request,admin_obj) # 搜索
  20.  
  21.     admin_obj.querysets = listing(request,admin_obj)        #分页
  22.  
  23.     return render(request,"kingadmin/table_data_list.html",locals())    # locals 传入局部变量

　　

3、table_data_list.html

  1. {% extends 'kingadmin/index.html' %}
  2. {% load kingadmin_tags %}
