显示Model所有的列名,有两种方法：

1. _meta.get_all_field_names() #removed in django 1.10
2. _meta.get_fields()

from attendence.models import *
Employee._meta.get_all_field_names() #removed in django 1.10
result=
[
'employeeip',
'first_name',
'entry_date',
'user_id',
'adjustment',
'last_name',
'employee_in_charge',
'user',
'email',
'punch'
]

Employee._meta.get_fields()
result=
(
    <ManyToOneRel: attendence.adjustment>,
    <ManyToOneRel: attendence.employeeip>,
    <ManyToOneRel: attendence.punch>,
    <ManyToOneRel: attendence.item>,
    <django.db.models.fields.related.OneToOneField: user>,
    <django.db.models.fields.CharField: first_name>,
    <django.db.models.fields.CharField: last_name>,
    <django.db.models.fields.EmailField: email>,
    <django.db.models.fields.DateTimeField: entry_date>
)
