UserSerializer başka bir serializers.py

Question

içine alınamıyor Bunu çözemedim.

UserSerializer() öğesini 'hesaplar' uygulamasından içe aktarmaya çalışıyorum, böylece 'comments' uygulamasındaki CommentSerializer() içine yerleştirebiliyorum.

'Beğenme' uygulamasından LikeSerializer() gibi başka bir seri hale getirici yerleştirmeye çalışırsam sorun olmaz.

Eğer comments.serializers.py dosyasında dikkatinizi çekerseniz, LikeSerializer parçalarını göremez ve UserSerializer'ı yorumlayabilir ve hata yapamaz.

Ancak UserSerializer() 'ı bir kez unutmadığımda, ImportError: cannot import name UserSerializer ile çarpıyorum.

Benim klasör yapısı:

/apps 
    /accounts 
    serializers.py 
    /comments 
    serializers.py 

** accounts.serializers.py

from ..memories.serializers import MemorySerializer 

class UserSerializer(serializers.ModelSerializer):

    password = serializers.CharField(write_only=True, required=False) 
    # password2 = serializers.CharField(write_only=True, required=False) 

    class Meta: 

     model = User 
     fields = ('id', 'email', 'first_name', 'last_name', 'created_at', 'relation', 'password', 'memories',)

'Uygulamalar' klasörünü python yolunuza ekleyin ve accounts.serializer'lardan içe aktarmayı deneyin. Ayrıca (bunlar uygulamaların bir alt dizin şartıyla) diğer ithalat tüm .. lider kaldırabilirsiniz
