django-rest-framework

问题 After having read through and completed the Django REST Framework tutorial, it is not completely obvious how one would implement a filter on a GET request. For example, ListAPIView is great for viewing all the instances of a Model in your database. However, if I wanted to limit the results (e.g. for a Book model, I might want to limit the results by publication date or author, etc.). It seems the best way to do this would be to create a custom Serializer, View, etc. and basically write

问题 models.py picture = models.ImageField(upload_to='Images/', default='/Images/None/No-img.jpg', blank=True,null=True) serializers.py class UserProfileSerializer(serializers.ModelSerializer): picture = serializers.ImageField(max_length=None, allow_empty_file=True, use_url=True) class Meta: model = UserProfile fields = ('id','picture',) read_only_fields=('id') But it's still showing as a required field, I can't make post request with image, is it a bug? 回答1: Maybe you should try setting the field

问题 I want that any user could create their own products with my RESTful API. For this purpose, I created a view that inherits ListCreateAPIView. The problem is that a user should only create products that he/she own, so when the instance of the Product model is created, I wanted that the field Owner corresponds to the user that is authenticated. Here's my Product model class Product(models.Model): owner = models.ForeignKey(User) name = models.CharField(max_length=30) Obviously my serializer is:

问题 I use DRF extension to se json list for model, and there i can debug with debug-toolbar that GET request, but how can i debug POST and PUT requests? I have this for settings in debug mode: INSTALLED_APPS += ('debug_toolbar',) MIDDLEWARE_CLASSES += ('debug_toolbar.middleware.DebugToolbarMiddleware',) DEBUG_TOOLBAR_PATCH_SETTINGS = False INTERNAL_IPS = ( '127.0.0.1' ) Now, when i try with Intercept redirects in debug-toolbar, it doesn't show me toolbar when i do POST . 回答1: I found django-silk

问题 I'm working with DRF and came across this issue. I have a third-party view which I'm importing in my urls.py file like this : from some_package import some_view urlpatterns = [ path('view/',some_view) ] but the issue I'm facing is since I have enabled default permission classes in my settings.py like this: REST_FRAMEWORK = { 'DEFAULT_AUTHENTICATION_CLASSES': ( 'rest_framework.authentication.TokenAuthentication', ), 'DEFAULT_PERMISSION_CLASSES':( 'rest_framework.permissions.IsAuthenticated', )

问题 I want to create permissions in Django Rest Framework, based on view + method + user permissions. Is there a way to achieve this without manually writing each permission, and checking the permissions of the group that the user is in? Also, another problem i am facing with, is that permission objects are tied up to a certain model. Since i have views that affect different models, or i want to grant different permissions on the method PUT, depending on what view i accessed (because it affects
