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>,
