How to differentiate between modules with same name in Django
For example, there is a 'reverse' module in Django which you can use for easy navigation between links. There is also a 'reverse' module available in DRF which can be used for creating custom API endpoints easily. I'm sure people at some point need to use both the modules at different stages, but how is Django going to differentiate between these two modules? They are called almost in the same way. Or am I wrong? Maybe either of the modules can be use to carry out both the tasks? -

Separate media settings for each app in django
I am working on building a django based blog-like site, it currently has one app. It contains a media folder which contains the images uploaded by the user. However, the MEDIA_URL and MEDIA_ROOT are specified in the main settings.py file. But in the future, there will be more apps containing more media, thus I want separate MEDIA_URL(s) and settings for each app. I tried writing the MEDIA_ROOT and MEDIA_URL separately in the apps.py file, but removing this from the main settings.py file results in an error. I also tried using FileSystemStorage, but even this needed me to have a MEDIA_URLS in the settings.py file. Please let me know if you need any more details. Any help is appreciated, thanks. -
Django Email - [Errno 2] No such file or directory
I am looking to allow the user to upload and send a document via email from my django app. When I go to send the email I get the error "[Errno 2] No such file or directory:". I have tried using a relative path as well as specifying the path but I get the same error either way. I can see that the file is being successfully loaded to that location...so I feel I must be missing something obvious here. Here is my view: def email(request): if request.method == "POST": form = EmailForm(request.POST,request.FILES) if form.is_valid(): post = form.save(commit=False) # post.published_date = timezone.now() post.save() email = request.POST.get('email') subject = request.POST.get('subject') message = request.POST.get('message') document = request.FILES.get('document') email_from = settings.EMAIL_HOST_USER recipient_list = [email] email = EmailMessage(subject,message,email_from,recipient_list) base_dir = 'media' email.attach_file('Desktop/WBU2/Poseidon/media/media/'+str(document)) #also tried email.attach_file('/media/'+str(document)) email.send() else: form = EmailForm() return render(request, 'docemail.html', {'form': form}) models.py class Mails(models.Model): email = models.EmailField() subject = models.CharField(max_length=1000) message = models.CharField(max_length=20000) document = models.FileField(upload_to='media') def __str__(self): return self.email -

Shared authentication between Laravel and Django apps coexisting in the same domain
I have a Laravel app which contains authentication code(and a lot more including Sass subscriptions and payment gateway integration), and a Django app which contains the main routes of the application. Both of them coexist in the same domain, let's say the Laravel app resides in the /auth url and the django project resides in the / url. I want to share the authentication between the two applications, (ie) if the user logs in using a Laravel form and is redirected to the Django route, he must stay authenticated. Any suggestions and links to relevant sources will be appreciated. Forgive me if the question seems too basic. Either of the applications can't be rewritten in another , since the Laravel app has too many functionalities to be rewritten and the Django part contains some machine learning functionality -
Probrems with URLconfs in Django
I include authentication URLconf in my urls.py: path('accounts/', include('django.contrib.auth.urls')), And it urlpatterns contains this: path('login/', views.LoginView.as_view(), name='login'), path('logout/', views.LogoutView.as_view(), name='logout'), path('password_change/', views.PasswordChangeView.as_view(), name='password_change'), path('password_change/done/', views.PasswordChangeDoneView.as_view(), name='password_change_done'), path('password_reset/', views.PasswordResetView.as_view(), name='password_reset'), path('password_reset/done/', views.PasswordResetDoneView.as_view(), name='password_reset_done'), path('reset/<uidb64>/<token>/', views.PasswordResetConfirmView.as_view(), name='password_reset_confirm'), path('reset/done/', views.PasswordResetCompleteView.as_view(), name='password_reset_complete'), But when I go to 127.0.0.1:8000/accounts debuger shows me this error: Page not found (404) Request Method: GET Request URL: http://127.0.0.1:8000/accounts Using the URLconf defined in locallibrary.urls, Django tried these URL patterns, in this order: 1. admin/ 2. catalog/ 3. ^static\/(?P<path>.*)$ The current path, accounts, didn't match any of these.

Django - Sorting posts by categories
I have two models -BlogPost and PostTopic. I would like to be able to filter by topic and see all the posts for that topic. This is working when I load up each url directly (i.e blog/cat/1), however when linking to this from the main blog post list view, I have tried the below template code: {% for topic in object_list %} <li><a href="{% url 'blog:BlogPostTopic_list' pk=topic.pk %}">{{ topic.topic }}</a></li> {% endfor %} However this doesn't work as it iterates over each topic mapped to the post (resulting in duplicates), rather than each unique topic. How do I link just to the unique topic page? models.py class PostTopic(models.Model): top_name = models.CharField(max_length=264, unique=True) def __str__(self): return self.top_name class BlogPost(models.Model): title = models.CharField(max_length=200) snippet = models.CharField(max_length=400, null=True) blog_pic = models.ImageField(upload_to='blog_pics', default='placeholder.jpg') hero_pic = models.ImageField(upload_to='blog_pics',blank=True) content = models.TextField() topic = models.ForeignKey(PostTopic, on_delete=models.CASCADE) create_date = models.DateTimeField(default=timezone.now) published_date = models.DateTimeField(blank=True, null=True) def get_absolute_url(self): return reverse("BlogPost_detail",kwargs={'pk':self.pk}) def __str__(self): return self.title views.py class BlogPostListView(ListView): model = BlogPost paginate_by = 4 def get_queryset(self): return BlogPost.objects.all().order_by('-published_date') class BlogPostDetailView(DetailView): model = BlogPost class BlogPostTopicListView(ListView): model = BlogPost template_name = 'blog/post_category.html' def get_queryset(self): return BlogPost.objects.filter(topic=self.kwargs['pk'] ) url url(r'^$',views.BlogPostListView.as_view(),name='BlogPost_list'), url(r'^(?P<pk>\d+)$',views.BlogPostDetailView.as_view(),name='BlogPost_detail'), url(r'^cat/(?P<pk>\d+)$',views.BlogPostTopicListView.as_view(), name='BlogPostTopic_list'), -
Who to display image in Django
I'm very new to Django so I saved an image into the database inside my models.py class Article(models.Model): title = models.CharField(max_length=120) content = models.TextField() active = models.BooleanField(default=True) picture = models.ImageField(upload_to='documents/pictures', null=True) now I want to display this image and I used the get_absolute_url method to get the current data from a row inside the db: def get_absolute_url(self): return f'/blog/{self.id}' In the views.py I return a renderfun with the params 'article':get_object_or_404(Article, id=my_id). Now in my template index.html I have this {% block content %} {{ article.content }} <img src="{{ article.picture }}" style="width: 200px; height: 200px;" /> {% endblock %} But if I open the developer console in chrome the img path is the same I set in models.py. The document/pictures folder is at the root of the django app. I tried to move it into the current app (Blog) but this also doesnt work. Do I have to set the media path in the settings.py ? I use django 3 and sqlite3 as db -

Django prefetch_related() in ListView class based view

Still no success. def get_queryset(self): posts = Post.objects.all().prefetch_related('pk__comment').all() comments = Comment.objects.all().prefetch_related('post') print(dir(posts)) print('---------------------') print(posts._prefetch_done) return posts.order_by('-date_posted') That still … -

However, once I do figure out the correct group it belongs to, I use this form to update the object with the appropriate group: class UpdateWatchmanForm(NewWatchmanForm): group = forms.ModelChoiceField(queryset=Group.objects.all()) class Meta(NewWatchmanForm.Meta): fields = NewWatchmanForm.Meta.fields + ("group",) I was curious if there might be a better way to reuse my NewWatchmanForm. Ideally, I'd like to avoid having to declare the group explicitly, something like this: class UpdateWatchmanForm(NewWatchmanForm): # group = forms.ModelChoiceField(queryset=Group.objects.all()) class Meta(NewWatchmanForm.Meta): fields = NewWatchmanForm.Meta.fields + ("group",) However, if I do that, I get this error: fields = NewWatchmanForm.Meta.fields + ("group",) TypeError: can only concatenate list (not "tuple") to list What is the correct way to subclass an existing ModelForm and include a ForeignKey field (without redefining forms.ModelChoiceField(...))? -
How to get current logged in user using django-microsoft-auth for Microsoft authentication?
I was following this guide to implement Microsoft authentication for my django app (https://django-microsoft-auth.readthedocs.io/en/latest/usage.html) using the django-microsoft-auth package. I just don't understand how I can get the currently logged in user id/email after the user has successfully logged in as the guide does not cover this? -

Django ORM: adding counter for all subclasses to (abstract) parent class
I am working on a restaurant app. I have different dish type classes (Pizza, Platter, etc) and in order to pass a dict or list (JSON-format) of ALL dishes to the JS-client, I was thinking of adding an (abstract) parent class Dish that would contain a counter or ID that identifies every dish (the aim being I can then use those ID's to access a large number of input fields and respective IDs in the html-form from the menu-page). Any ideas on the best way to do this? I tried using InheritanceManager(), but that doesn't work if my Dish class is abstract. If it is not abstract (which it should be, I'd say), I get a You are trying to add a non-nullable field 'dish_ptr' error. Not sure my whole approach even makes sense, but can't think of a better way to work with large HTML-forms with 50-100 input fields (menu items).
