How to use the `path` function instead of the `url` function
I am learning how to use django-rest-framework to build my front-end separation project. I follow the django official documentation using the path function instead of the url function for development. But when I added django-rest-framework, I found that django-rest-framework is still using the url function. In order to maintain code consistency, I wrote the following code: In 'quickstart/urls.py'('quickstart' is my app name) from django.urls import path, include from rest_framework import routers from quickstart import views router = routers.DefaultRouter() router.register('users', views.UserViewSet) router.register('groups', views.GroupViewSet) app_name = 'quickstart' urlpatterns = [ path('', include(router.urls)), path('api-auth/', include('rest_framework.urls')), ] In 'tutorial/urls.py'('tutorial' is project name) from django.contrib import admin from django.urls import path, include urlpatterns = [ path('admin/', admin.site.urls), path('quickstart/', include('quickstart.urls')), ] However, there was a problem with the program. When I visited 127.0.0.1/quickstart/users, I got the following error: Internal Server Error: /quickstart/users/ Traceback (most recent call last): File "C:\dev\tomorrow-headline\venv\lib\site-packages\rest_framework\relations.py", line 376, in to_representation url = self.get_url(value, self.view_name, request, format) File "C:\dev\tomorrow-headline\venv\lib\site-packages\rest_framework\relations.py", line 314, in get_url return self.reverse(view_name, kwargs=kwargs, request=request, format=format) File "C:\dev\tomorrow-headline\venv\lib\site-packages\rest_framework\reverse.py", line 50, in reverse url = _reverse(viewname, args, kwargs, request, format, **extra) File "C:\dev\tomorrow-headline\venv\lib\site-packages\rest_framework\reverse.py", line 63, in _reverse url = django_reverse(viewname, args=args, kwargs=kwargs, **extra) File "C:\dev\tomorrow-headline\venv\lib\site-packages\django\urls\base.py", line 90, in reverse return iri_to_uri(resolver._reverse_with_prefix(view, prefix, *args, … -

I've just finished switching(or trying to) from SQlite toPostgresql for my Django 1.11, on my Centos 7 server.

Django datetimeinput widget - validate as datetime, but convert to unix time before saving
I have a django form that looks like this: class AnnouncementCreationForm(forms.ModelForm): def __init__(self, *args, **kwargs): super().__init__(*args, **kwargs) self.fields['publish_datetime'].widget = forms.DateTimeInput() self.fields['publish_datetime'].widget.attrs.update({'placeholder': 'YYYY-MM-DD HH:MM:SS'}) self.fields['publish_datetime'].required=False self.fields['document'].required=False class Meta: model = CompanyAnnouncement exclude = ['company'] Where the model looks like this: class CompanyAnnouncement(models.Model): class Meta: ordering = ['publish_datetime'] verbose_name = 'Company Announcement' verbose_name_plural = 'Company Announcements' company = models.ForeignKey(Company, on_delete=models.CASCADE) publish_datetime = models.DecimalField(decimal_places=6, max_digits=18, help_text='Leave blank to publish immediately') title = models.CharField(max_length=100) document = models.FileField(upload_to='company_announcements', help_text='', null=True, blank=True) I have overridden the fault input widget for the publish_datetime to use a DateTimeInput, in spite of the value being a decimal. This is because I want the users to input a datetime, and then convert it to unix time before saving it in the db. This is done in the view: class AccouncementCreateView(LoginRequiredMixin, CreateView): form_class = AnnouncementCreationForm template_name = 'create_announcement.html' redirect_unauthenticated_users = True success_url = '/users/my_companies' def form_valid(self, form): form.instance.company = Company.objects.filter(crn=self.kwargs['company_spec_url'])[0] print(type(form.instance.publish_datetime)) # Returns 'datetime.datetime' if form.instance.publish_datetime: form.instance.publish_datetime = form.instance.publish_datetime.timestamp() else: form.instance.publish_datetime = dt.now().timestamp() form.save() return super().form_valid(form) The latter half of the if statement (i.e. the input field is blank) works, and it successfully stores the current unix time in the db, but the first half does not work. The form complains, … -

How do I get django template to recognize manytomanyfield comparison?
In my project, I am currently trying to access a manytomany field and compare it to another. I have several cases where I am doing something similar and it is working . The difference in this case is that I am trying to essentially say if one of the values in this many to many field equals a value in this other manytomanyfield, then do something.... Here is my code... Book(models.Model): author = models.ManyToManyField(Name) publisher = models.ManyToManyField(Name) In my Django template I am trying to do something like... {% If author_set.all in form.initial.publisher_set.all %} {{ author.name }} {% endif %} The example above is a simplified version of what I'm trying to do....I'm essentially trying to compare the manytomany fields and if any of the values match, perform an action. I've been at this most of today and have tried several combinations. If I do something like {% if user in form.initial.publisher.all %} This works fine. I'm struggling to try and figure out how I can compare manytomanyfields. I suspect the user query works fine because it's not a manytomanyfield. I'm thinking my format is off. I have tried to use the _set to both publisher and author as well … -

Django REST API is not returning all objects
I have a model of an "Instrument" which includes a field "active". When I go to the rest api it seems that all of the Instruments are listed, but there is one I have found that never appears.

How to serve static content with Nginx and Django Gunicorn when using Traefik
I have a web application (Django based) that is utilising multiple containers: Web Application (Django + Gunicorn) Traefik (acting as the reverse proxy and SSL termination) Database which is used with the Web application Redis which is used with the Web application According to some of the documentation I have read, I should be serving my static content using something like NGINX.

I have implemented Django notification in my index view.

Google OAuth2 not issuing a refresh token even with access_type='offline'?
This question is similar to Not receiving Google OAuth refresh token, but I have already specified access_type='offline' as suggested in the comments to the accepted solution.
