我使用Django 1.8并收到以下错误：
ValueError: Lookup failed for model referenced by field gallery.likeGroup.likeGroupCustomerId: gallery.customers
models.py 如下所示：
from django.db import models
class artist(models.Model):
artistName = models.CharField(primary_key = True, max_length = 20)
artistBirthPlace = models.CharField(max_length = 20)
artistAge = models.IntegerField(default = 0)
artistStyle = models.CharField(max_length = 20, default = 'NULL')
def __str__(self):
return self.artistName
class customer(models.Model):
customerId = models.IntegerField(primary_key = True)
customerName = models.CharField(max_length = 20)
customerAddress = models.CharField(max_length = 20)
customerAmount = models.IntegerField(default = 0)
def __str__(self):
return self.customerName
class artwork(models.Model):
artworkTitle = models.CharField(primary_key = True, max_length = 20)
artworkYear = models.IntegerField(default = 0)
artworkPrice = models.IntegerField(default = 0)
artworkArtist = models.ForeignKey(artist, db_column = 'artistName')
artworkType = models.CharField(default = 'NULL', max_length = 20)
def __str__(self):
return self.artworkTitle
class group(models.Model):
groupName = models.CharField(primary_key = True, max_length = 20)
def __str__(self):
return self.groupName
#class likeGroup(models.Model):
# likeGroupCustomerId = models.IntegerField(default = 0)
# likeGroupName = models.ForeignKey(group, db_column = 'groupName')
# def __str__(self):
# return self.likeGroupName
class classifiedInto(models.Model):
classifiedIntoGroupName = models.ForeignKey(group, db_column = 'groupName')
classifiedIntoArtworkTitle = models.ForeignKey(artwork, db_column = 'artworkTitle')
class likeArtist(models.Model):
likeArtistCustomerId = models.ForeignKey(customer, db_column = 'customerId')
likeArtistArtistName = models.ForeignKey(artist, db_column = 'artistName')
admin.py 看起来像：
from django.contrib import admin
from .models import artist
class artistAdmin(admin.ModelAdmin):
list_display = ('artistName', 'artistAge', 'artistBirthPlace','artistStyle')
list_filter = ['artistName', 'artistAge', 'artistBirthPlace','artistStyle']
search_fields = ['artistName', 'artistAge', 'artistBirthPlace','artistStyle']
admin.site.register(artist, artistAdmin)
from .models import customer
class customerAdmin(admin.ModelAdmin):
list_display = ('customerId', 'customerName', 'customerAddress', 'customerAmount')
list_filter = ['customerId', 'customerName', 'customerAddress', 'customerAmount']
search_fields = ['customerId', 'customerName', 'customerAddress', 'customerAmount']
admin.site.register(customer, customerAdmin)
from .models import artwork
class artworkAdmin(admin.ModelAdmin):
list_display = ('artworkTitle', 'artworkYear', 'artworkYear', 'artworkPrice', 'artworkArtist')
list_filter = ['artworkTitle', 'artworkYear', 'artworkYear', 'artworkPrice', 'artworkArtist']
search_fields = ['artworkTitle', 'artworkYear', 'artworkYear', 'artworkPrice', 'artworkArtist']
admin.site.register(artwork, artworkAdmin)
from .models import group
class groupAdmin(admin.ModelAdmin):
list_filter = ['groupName']
search_fields = ['groupName']
admin.site.register(group, groupAdmin)
#from .models import likeGroup
#class likeGroupAdmin(admin.ModelAdmin):
# list_filter = [ 'likeGroupName']
# search_fields = ['likeGroupName']
#admin.site.register(likeGroup, likeGroupAdmin)
from .models import likeArtist
class likeArtistAdmin(admin.ModelAdmin):
list_display = ('likeArtistCustomerId', 'likeArtistArtistName')
list_filter = ['likeArtistCustomerId', 'likeArtistArtistName']
search_fields = ['likeArtistCustomerId', 'likeArtistArtistName']
admin.site.register(likeArtist, likeArtistAdmin)
from .models import classifiedInto
class classifiedIntoAdmin(admin.ModelAdmin):
list_display = ('classifiedIntoGroupName', 'classifiedIntoArtworkTitle')
list_filter = ['classifiedIntoGroupName', 'classifiedIntoArtworkTitle']
search_fields = ['classifiedIntoGroupName', 'classifiedIntoArtworkTitle']
admin.site.register(classifiedInto, classifiedIntoAdmin)
当我尝试从Django应用程序中打开 LikeGroup 时，它会出错：
/ admin / gallery / likegroup /
中的OperationalError（1054，＆＃34;未知列＆＃39; gallery_likegroup.id＆＃39;在＆＃39;字段列表＆＃39;＆＃34;）
