Django：TypeError：int（）引数は文字列、バイトのようなオブジェクトまたは数値でなければなりません

Question

助けてください！私は答えを探してみましたが、私はこの問題があまりにも一般化された十分な解決策をとるには特異だと考えています。

正確には、このエラーが開始されたときにポイントを突き止めるのは非常に難しいです。私はサイトが最後に働いていた時期を知るために今や多くの変更を試みました。私はこれに非常に新しいです。そして、それは完全に独学です。私はあなたを保証することができます、明らかになります。

移行しようとすると、私はこのエラーが表示されます。

編集：ここでは.models.py

class Store(models.Model):

    def __str__(self): 
     return self.name 


class Product(models.Model): 
    type = models.CharField(max_length=250) 
    owner = models.ForeignKey(User) 

    def __str__(self): 
     return self.type 


class Receipt(models.Model): 
    store = models.ForeignKey(Store) 
    date = models.DateField() 
    line_items = models.ManyToManyField(Product, through='ReceiptProduct')

Answer 1

問題があります。

問題を引き起こしていたアプリ内のmigrationsフォルダを削除しました。そして、 ''を実行して再作成しました。その後、サーバーに移行しました。
