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>,
