No, I don't think so, first I edit my Model like this:
in model.py:
Class UeSetting(model.Model):
title =
models.CharField('title',max_length=11,unique=True)
changetime =
models.DateTimeField('changetime',auto_now_add=True)
def __unicode__(self):
return self.title
class BtsSetting(models.Model):
title =
models.CharField('title',max_length=11,unique=True)
changetime =
models.DateTimeField('changetime',auto_now_add=True)
def __unicode__(self):
return self.title
class CheSetting(models.Model):
title =
models.CharField('title',max_length=11,unique=True)
changetime =
models.DateTimeField('changetime',auto_now_add=True)
def __unicode__(self):
return self.title
In the same time edit admin.py:
class
UeSettingAdmin(admin.ModelAdmin):
list_display = ['title',
'changetime']
ordering =
['changetime']
search_fields = ('title',
'changetime')
class
BtsSettingAdmin(admin.ModelAdmin):
list_display = ['title',
'changetime']
ordering =
['changetime']
search_fields = ('title', 'changetime')
class
CheSettingAdmin(admin.ModelAdmin):
list_display = ['title',
'changetime']
ordering =
['changetime']
search_fields = ('title', 'changetime')
admin.site.register(models.UeSetting,
UeSettingAdmin)
admin.site.register(models.BtsSetting,
BtsSettingAdmin)
admin.site.register(models.CheSetting, CheSettingAdmin)
then I use command lik this:
#python mange.py syncdb
#python mange.py runserver
at last, when I click the BtsSetting CheSetting in web browser are ok
to show, but only when I click UeSetting, the browser will show this
error:
DatabaseError at /adminaddress/uesetting
no such column: address_uesetting.changetime
I have tried to run "mange.py syncdb" many time, but nothing change.
FYI, my setting in batabase is :
DATABASES = {
'default': {
'ENGINE': 'sqlite3', # Add 'postgresql_psycopg2',
'postgresql', 'mysql', 'sqlite3' or 'oracle'.
'NAME': './data.db', # Or path to database
file if using sqlite3.
'USER': '', # Not used with sqlite3.
'PASSWORD': '', # Not used with sqlite3.
'HOST': '', # Set to empty string for
localhost. Not used with sqlite3.
'PORT': '', # Set to empty string for
default. Not used with sqlite3.
}
}
