我已经编写了以下模型，但可能有问题，因为 Django 管理站点中返回的不是标签名称，而是标签对象：
from os import path
from django.db import models
from django.contrib import admin
from django.core.files.storage import FileSystemStorage
projectDirPath = path.dirname(path.dirname(__file__))
storeImageDir = FileSystemStorage(location=projectDirPath + '/couponRestApiApp/static')
class tags(models.Model):
""" This is the tag model """
tag = models.CharField(max_length=15) # Tag name
tagDescription = models.TextField() # Tag Description
tagSlug = models.CharField(max_length=400) # Extra info can be added to the existing tag using this field
createdAt = models.DateTimeField(auto_now_add=True)
updatedAt = models.DateTimeField(auto_now=True)
class stores(models.Model):
""" This is the store model """
storeName = models.CharField(max_length=15) # Store Name
storeDescription = models.TextField() # Store Description
storeURL = models.URLField() # Store URL
storePopularityNumber = models.IntegerField(max_length=1) # Store Popularity Number
storeImage = models.ImageField(upload_to=storeImageDir) # Store Image
storeSlug = models.CharField(max_length=400) # This is the text you see in the URL
createdAt = models.DateTimeField(auto_now_add=True) # Time at which store is created
updatedAt = models.DateTimeField(auto_now=True) # Time at which store is updated
storeTags = models.ManyToManyField(tags) # All the tags associated with the store
def getStoreTags(self):
p = self.storeTags.objects.all()
return p.tag
class coupons(models.Model):
""" This is the coupon model """
couponValue = models.CharField(max_length=4) # Coupon value in RS.
couponDescription = models.TextField() # Coupon Description
couponURL = models.URLField() # Coupon click URL
couponStore = models.ForeignKey(stores) # Key of coupon to store
tagName = models.ForeignKey(tags,on_delete=models.PROTECT) # Tag names associated to coupon
success = models.TextField() # Count of the number of times people have made it work
failures = models.TextField() # Count of the number of times this has failed
lastTested = models.DateTimeField(auto_now=True) # When was the coupon last tested
createdAt = models.DateTimeField(auto_now_add=True)
updatedAt = models.DateTimeField(auto_now=True)
class app(models.Model):
""" This is the application model which is using the API """
appName = models.CharField(max_length=20) # Application name
appDomain = models.CharField(max_length=20) # Application description
appKey = models.TextField() # Application Key
createdAt = models.DateTimeField(auto_now_add=True) # Time at which Application is added is created
updatedAt = models.DateTimeField(auto_now=True) # Time at which Application details are updated
class subscriptions(models.Model):
""" These are the emails that are subscribing """
app = models.CharField(max_length=20) # The application where the email came from
store = models.CharField(max_length=20) # The optional store on which the email wants an update
tag = models.CharField(max_length=20) # The optional tag on which the email wants an update
emailID = models.EmailField() # EmailID of the registered user
active = models.BooleanField(default=True) # They may have unsubscribed
createdAt = models.DateTimeField(auto_now_add=True) # Time at user subscribed to the alerts
updatedAt = models.DateTimeField(auto_now=True) # Time at which user updated its subscription
class tagsAdmin(admin.ModelAdmin):
list_display = ('tag', 'tagDescription', 'tagSlug')
class storesAdmin(admin.ModelAdmin):
list_display = ('storeName','storeDescription','storeURL',
'storePopularityNumber','storeImage',
'storeSlug','createdAt','createdAt','getStoreTags'
)
class couponsAdmin(admin.ModelAdmin):
list_display = ('couponValue','couponDescription','couponValue',
'couponURL', 'couponStore','tagName','success',
'failures','createdAt','updatedAt'
)
class appsAdmin(admin.ModelAdmin):
list_display = ('appName','appDomain','appKey',
'createdAt','updatedAt'
)
class subcriptionsAdmin(admin.ModelAdmin):
list_display = ('app','store','tag','emailID',
'active','createdAt','updatedAt'
)
admin.site.register(tags,tagsAdmin)
admin.site.register(stores,storesAdmin)
admin.site.register(coupons,couponsAdmin)
admin.site.register(app,appsAdmin)
admin.site.register(subscriptions,subcriptionsAdmin)
但是，当我使用 Django 管理站点在优惠券类别下保存数据而不是返回标签标签对象的名称时，商店也会发生同样的情况......我做错了什么......请帮帮我。我已经注册了所有条目，但仍然无法正常工作。
