Django:将后台返回的数据填充到select下拉框中

select选择框如下：

<select data-placeholder="选择项目..." class="form-control" name="update_project_name" id="update_project_name">
　　<option value="">请选择项目</option>
　　{% for key,value in project.items %}
　　<option value="{{ value }}" hassubinfo="true">{{ key }}</option>
{# <option value="120000" hassubinfo="true">天津</option>#}
{# <option value="130000" hassubinfo="true">河北省</option>#}
　　{% endfor %}
</select>

后台通过查询数据库，然后组装数据格式为字典格式，返回数据，前台通过{% for key,value in project.items %}遍历该字典，取得对应的键值对

def smoke_test_case(request):
    project_data = {}
    db = pymysql.connect("localhost", "root", "***", "****", charset='utf8')
    cursor = db.cursor()
    sql = 'SELECT project_name,project_code FROM project'
    cursor.execute(sql)
    results = cursor.fetchall()
    print list(results)
    for i in list(results):
        project_data[i[0]]=i[1]
    print project_data
    return render(request, "showcase/smoke_test_case.html", {'project': project_data})
