Django Rest Swagger 2 not parsing Serializer FieldField correctly
Let us say I have the following serializer: class FileUploadSerializer(serializers.Serializer): file = serializers.FileField(max_length=100) My view looks like this: class FileUploadView(generics.CreateGenericAPIView): serializer_class = serializers.FileUploadSerializer parser_classes = (parsers.FileUploadParser,) def post(self, request): # do something here I expected the swagger UI to generate a file upload button that you can click to choose a file from the file system. Instead, I was asked to input a JSON data: In the older version of the Django Swagger, I can just specify the parameter type as file in the YAML docstrings. However, I am using Django Swagger 2+ where YAML docstrings are no longer supported. -

Django Write Authentication Redirect for Blackboxed Route URLs
I'm using a django library called django-dashing that has a predefined set of urls that render a dashboard. I import them like this urlpatterns = [ ... url(r'^dashboard/', include(dashing_router.urls)), ... ] I want the router to be accessible only by administrators, which I can do with some config settings within django-dashing. However, when a non-admin user attempts to access /dashboard/, I want to redirect them to django's /admin/ panel to have them log in, instead of throwing the 403 that django-dashing does. Since the django-dashing views are effectively blackboxed, I was wondering if there was a way to write a 'pre-view' that would intercept the request to /dashboard/, run some code – specifically, doing the appropriate redirects – and then continue onto the actual dashboard. I know this would be easy enough to do by writing two urls, like /dashboard-auth/ which redirects to /dashboard/, but I don't want the user to have to go to one URL to get to another Any suggestions? -
How can I post params to be used as an object in Django
I want to send an ajax Post request to my server with a param to be used like an object: student_name = request.data.get('student_info', {}).get('name') When I send the params like this: student_info: {"name":"Tom", "age": 20} It produce the following error: AttributeError: 'unicode' object has no attribute 'get' The best answer is what I don't need to change my back-end, and solve my problem by sending data properly.

Wagtail Admin Add Page Returns 404 in Docker Container
When running outside of Docker; everything operates as expected. However, when running inside a container; some Wagtail admin pages return 404. These admin pages all work (ie return 200) when inside a Docker container: http://localhost:8000/admin http://localhost:8000/admin/pages/ http://localhost:8000/admin/pages/2/add_subpage/ I have a number of page types that all work outside of Docker.

FieldError: Unknown field(s) (created_at, modified_at) specified for Account
I am trying to create a timestamp for my model Account, but I don't want my two time stamps (created_at and modified_at) to be editable or even viewable by the user. Everything works fine and as expected until I add editable=False to the created_at and modified_at fields. Here is my model: class Account(models.Model): account_name = models.CharField(max_length=25) active = models.BooleanField(default=True) created_at = models.DateTimeField(null=True, blank=True, editable=False) modified_at = models.DateTimeField(null=True, blank=True, editable=False) def save(self): if self.id: self.modified_at = datetime.datetime.now() else: self.created_at = datetime.datetime.now() super(Account, self).save() class Meta: ordering = ('id',) Here is the obscure error I get when I try to do anything (migrate, runserver, etc): django.core.exception.FieldError: Unknown field(s) (created_at, modified_at) specified for Account As soon as I remove editable=False from both fields, everything works fine. Is this a Django bug? Is there a better way to make the field non-viewable and non-editable by the user? I am using Django 1.9 and Python 3.6.1. Thanks for the help, let me know if you need me to post anything else (views, serializers, etc). Full traceback: https://pastebin.com/JXDEpfUE -

Django FilteredSelectMultiple
I have a problem trying to use the django FilteredSelectMultiple with forms. When I use this in admin with a model that I try to register everything works as expected, but when I try to create a view and use the FilteredSelectMultiple inside a form something weird happens. The form is rendered as I want, but the choices I make are not saved on the right side of the select field, like this: http://imgur.com/a/1GG9V. The data is saved in the database but everytime I enter this view again, the data is all in the left side of the selected box. Here is the code I am using: distribuidores=forms.ModelMultipleChoiceField(queryset=User.objects.filter(groups__name="distribuidores"), required=True,widget=FilteredSelectMultiple("Distribuidores",is_stacked=False)) class Media: css = {'all': ('/static/admin/css/widgets.css',),} js = ('/admin/jsi18n/',) -

Order queryset by related M2M fields Django
