Question

我对date_joined字段使用基本的用户模型。

我已经在Google搜索中做了几乎所有的工作。

views.py

def list(self, request, *args, **kwargs):
    form = ModelInfoForm(request.GET or None)
    serializer = UserSerializer(self.queryset, many=True)

    return Response({'users':serializer.data, 'form':form}, template_name = 'user/userinfo.html')

serializers.py

class UserSerializer(serializers.ModelSerializer):

    class Meta:
        model = User
        fields = ('username', 'email', 'first_name', 'last_name', 'is_superuser', 'is_staff', 'is_active', 'date_joined',
                  'get_absolute_url')

settings.py

USE_L10N = False

USE_TZ = False

DATETIME_FORMAT = '%d-%m-%Y-%H-%M-%S'

template.html

<td>{{ user.date_joined }}</td> 

<td>{{ user.date_joined|date:"d:m:Y H:i:s" }}</td>

我得到了这样的结果

{{ user.date_joined }} 

=> 2018-06-14T12:02:21

{{ user.date_joined|date:"d:m:Y H:i:s" }} 

=> (nothing)

{{ user.date_joined|date:"DATETIME_FORMAT" }}

=> (nothing)

{{ user.date_joined|date:DATETIME_FORMAT }}

=> (error)

我还将用户解决方案用于其他模型。

models.py

class TimeStampedModel(models.Model):
    created = models.DateTimeField(auto_now_add=True)
    updated = models.DateTimeField(auto_now=True)

Answer 1

您可以在输出格式中为joined_date指定格式参数。

class UserSerializer(serializers.ModelSerializer):
   date_joined = serializers.DateTimeField(format="<Your format>")

class Meta:
    model = User
    fields = ('username', 'email', 'first_name', 'last_name', 'is_superuser', 'is_staff', 'is_active','get_absolute_url')

Answer 2

我用自定义的DATETIME_FORMAT解决了

settings.py

DATETIME_FORMAT = '%Y-%m-%d %H:%m'

serializers.py

class UserSerializer(serializers.ModelSerializer):
    date_joined = serializers.DateTimeField(format=base.DATETIME_FORMAT, input_formats=None)

    class Meta:
        model = User
        fields = ('username', 'email', 'first_name', 'last_name', 'is_superuser', 'is_staff', 'is_active', 'date_joined',
                  'get_absolute_url', 'pk')

如何在Django中更改date_joined和datetimefield格式？
