在我的项目中，我有两个应用程序，beacon_info 和报价，我需要将商店用作我的 beacon_info 应用程序到报价的外键

Question

Beacon_info 应用模型 下面显示的代码是我想在另一个应用程序中将其作为外键的字段，如下所述。

from django.db import models
from django.utils.encoding import smart_unicode
from django.utils import timezone
from datetime import datetime

    class store(models.Model):
            store_name = models.CharField('Store Name',max_length=100)
            store_id = models.CharField('Store_ID', max_length=20, unique=True)
            store_email = models.EmailField('Email_ID', max_length=254)
            address = models.CharField('Address', max_length=250)
            country = models.CharField('Country', max_length=50)
            state = models.CharField('State', max_length=50)
            city = models.CharField('City',max_length=50)
            pincode = models.CharField('Pincode', max_length=15)
            contact_no = models.CharField('Contact', max_length=15)
            createdat = models.DateTimeField(auto_now=True)
            def __unicode__(self):
                return smart_unicode(self.id)

提供应用的模型

from django.db import models
from django.utils.encoding import smart_unicode
from beacon_info.models import *
from django.utils import timezone
from datetime import datetime
class offer(models.Model):
    offer_code = models.CharField(max_length=50)
    store_code = models.ForeignKey('beacon_info.models.store')
    entry_exit_type = models.CharField(max_length=50, null=True)
    offername = models.CharField(max_length=100, null=True)
    description = models.TextField()
    membership = models.CharField(max_length=5, default=1)
    start_time = models.DateTimeField()
    end_time = models.DateTimeField()
    createdat =models.DateTimeField(auto_now_add=True)
    def __unicode__(self):
        return smart_unicode(self.offername)

Answer 1

models.ForeignKey('beacon_info.models.store')

应该是

models.ForeignKey('beacon_info.store')

惯例是使用app_name.model_name，不需要包含models。

https://docs.djangoproject.com/en/1.7/ref/models/fields/#django.db.models.ForeignKey

To refer to models defined in another application, you can explicitly specify a model with the full application label. For example, if the Manufacturer model above is defined in another application called production, you’d need to use:
class Car(models.Model):
     manufacturer = models.ForeignKey('production.Manufacturer')

在我的项目中，我有两个应用程序，beacon_info 和报价，我需要将商店用作我的 beacon_info 应用程序到报价的外键

In my project i have two apps , beacon_info and offers, i need to use the store as a foreign key from my beacon_info app to offers

python
