Why does this Error Message ModuleNotFoundError: No module named 'betterforms' show up and how to avoid it?

Django EmailValidator validating trailing dots
I'm using Django 1.9, and EmailValidator seems to be validating trailing dots in email ids. faulty_email = 'sid@h.in.' user.email = faulty_email user.save() The above piece of code runs smoothly even though email is an EmailField, which has EmailValidator. The weird thing is, when I run the validation manually, it throws a ValidationError. In [1]: from django.core.validators import validate_email In [2]: faulty_email = 'sid@h.in.' In [3]: validate_email(faulty_email) --------------------------------------------------------------------------- ValidationError Traceback (most recent call last) <ipython-input-3-bdbbd57d5fe1> in <module>() ----> 1 validate_email(faulty_email) /usr/local/lib/python2.7/dist-packages/django/core/validators.pyc in __call__(self, value) 201 except UnicodeError: 202 pass --> 203 raise ValidationError(self.message, code=self.code) 204 205 def validate_domain_part(self, domain_part): ValidationError: [u'Enter a valid email address.'] Does anyone know what the issue is? -
Serialize Admin Change List Filters for Celery
Given the following conditions: A non-trivial admin action must be performed on thousands of rows. The rows are the result of complex custom admin filters. What's the best way to handle this scenario? We have considered Synchronously handling the request within the request/response cycle. This takes too long. Sending the resulting QuerySet to celery via Pickle, but the Pickle serializer is considered to be insecure. Reconstructing the QuerySet in a Celery task from admin URL query parameters. Would require delving into private Django admin methods. -
Django : Add post id to the slug only if it already exists
Here is my code to generate slug,in models.py, def save(self): self.slug = slugify(self.title) super(Post, self).save() I want to check if the slug already exists in my database or not and then only add the id to that slug. Only way I can think of now is to add id in every slug by doing this, def save(self): super(Post, self).save() if not self.slug: self.slug = slugify(self.title) + "-" + str(self.id) self.save() The problem is, it adds id in all the slugs. So how can I check if a slug already exists due to same title and then only add the id to that slug? -
Update contents of a form without refreshing the page in django
I am working on a django application. In this application a user can upload an image. Once the image is uploaded an image classifier runs on the image and an image_description form is auto-filled based on the classifier output. When the form is submitted the item is displayed in a new page. This is my url patterns urls.py urlpatterns = [ path('', views.index, name='home'), path('accounts/', include('django.contrib.auth.urls')), path('signup/', views.signup, name='signup'), path('items/', views.item_list, name='item_list'), path('items/upload/description/', views.upload_item, name='upload_item'), path('items/<int:pk>/', views.delete_item, name='delete_item'), path('items/upload/image_classification/', views.image_classification, name='image_classification'), ] here item_list is the page where all items are displayed. This page is displayed once the form is submitted. upload_item page contains a form to upload the image and also contains another form that is auto-filled once the classifier runs on the image. image_classification runs when upload image button is clicked.this happens in the upload_item page. views.py def item_list(request): items = Item.objects.all() return render(request, 'item_list.html', {'items':items}) def upload_item(request): if request.method == 'POST': form_des = ItemForm(request.POST, request.FILES) if form_des.is_valid(): form_des.save() return redirect('item_list') else: form_des = ItemForm() return render(request, 'upload_item.html', {'form_des': form_des}) def image_classification(request): form_des = ItemForm() if request.method == 'POST': if 'file' in request.FILES: handle_uploaded_file(request.FILES['file'], str(request.FILES['file'])) img = np.expand_dims(cv2.resize(cv2.imread(os.path.join('./media/item/img/', str(request.FILES['file']))), (170, 100)), axis=0) cat_prediction = cat_classifier.predict_classes(img)[0] pattern_prediction = pat_classifier.predict_classes(img)[0] … -

How to make django-hosts subdomains redirect even when user is not logged in
I am using django-hosts to create user subdomains, e.g sally.website.com will redirect to sally's profile. I understand how to do that if sally is logged in but let's say a random user john tries to access sally's profile at sally.website.com, how would I make this work with django-hosts? Kind of like how whether you are logged in or not if you go to facebook.com/sally it will return sally's page. I included the views.py and hosts.py to help clarify things. The users created url is stored in the dashboard views as url. So what I want to do is make that url returns sally's profile regardless of her login status. hosts.py: from django.conf import settings from django_hosts import patterns, host from main import views host_patterns = patterns('', host(r'www', settings.ROOT_URLCONF, name='www'), # <-- The `name` we used to in the `DEFAULT_HOST` setting host(r'', 'path.to.custom_urls', name='wildcard'), ) views.py: def dashboard(request): if request.user.is_authenticated == True: name = request.user.first_name name2= name[0].upper() + name[1:] if request.method == "POST": choosestorename = request.POST.get("choosestorename").lower() preurl = request.user.username.split("@")[0] baseurl = request.META.get('HTTP_HOST').lower() url = choosestorename+ "." + preurl + "." + baseurl request.session[url] = url print(url) return render(request, 'main/dashboard.html', {'name2':name2}) elif request.user.is_authenticated == False: return redirect('home') else: return redirect('home') -
ImportError of mixins for Django 1.8 in Cygwin64

Based on answers of previous questions, I had installed the following: Django==1.11.18 django-filer==1.4.4 django-picklefield==2.0 django-polymorphic==2.0 And I think they solved the problem, but the project which I'm working on uses Django 1.8 , and when I install the versions of these that are compatible with Django 1.8, the mixins error comes back.

Here are my serializers and views serializers: class … -
Getting user's old image if no image is selected
I have a form that takes in user data like bio, profile picture, gender, etc. and upon submission either creates this new row about the user or updates the existing row. This will only work if the user uploads an image. If no image is uploaded for the profile picture, then the form doesn't submit. How can I make it so that if the user didn't upload a profile picture, then it'll keep the user's previous profile picture and still submit? Here's my code: class ProfileSettings(UpdateView): model = Profile template_name = 'blog/settings.html' form_class = ProfileForm success_url = reverse_lazy('blog:settings') def post(self, request, *args, **kwargs): form = self.form_class(request.POST, request.FILES) if form.is_valid(): bio = form.cleaned_data['bio'] gender = form.cleaned_data['gender'] avatar = form.cleaned_data['avatar'] Profile.objects.update_or_create(user=self.request.user, defaults={'avatar':avatar, 'bio':bio, 'gender':gender}) return HttpResponseRedirect(self.success_url) -
Annotate but with non-Django supplied values
Is there any way to append a non-Django supplied value to a query? For instance, to find out if a store closed, I may run a function called get_closed_stores() which returns a list of closed stores. Stores Closed [00090, 00240, 00306, 00438, 03005, 05524] Great, now we have store numbers for stores that are closed. Lets get those actual store objects. Query Store.objects.filter( store_number__in=[00090, 00240, 00306, 00438, 03005, 05524] ) We now have the QuerySet, but we have absolutely no way to detect when the store closed, because the database doesn't contain any information about emergency closings, but Sharepoint does. So back at get_closed_stores() we can return the Date Closed alongside the store number so our Closed Stores List (dictionary) would look more like below: Store List with Dates { [00090, '1/28/19 5:00PM'], [00240,'1/28/19 5:00PM'], [00306, '1/28/19 5:00PM'], [00438,'1/28/19 5:00PM'], [03005,'1/28/19 5:00PM'], [05524, '1/28/19 5:00PM'] } Now that the dates are with my store numbers, I can add this to my Queryset (ideally) and access it from my front end. So annotate() would be ideal here if I were working with anything Django ORM related, but when it comes to "injecting" external data, what is it I'm looking for?
