Django updateview (cbv and fbv) to upload multiple files not working
I am trying to upload files (single and multiple) with an updateview (cbv and fbv) via an update template but I keep getting a 'This field is required' error when i submit and the files don't get uploaded of course. All required fields are filled with valid data types and the file upload fields are optional, so I don't understand where this error is coming from. I strongly suspect there's an error in my view specifically in the 'if form.is_valid():' section. I tried using both fbv and cbv, still i get the same error. I have even created a seperate model for the multiple files upload field and a seperate form class that extends the updateform class, still i get the same error. I am stumped. Please whatever help can be rendered will be highly appreciated. Thanks. this is the model for the multiple files upload field class shareCapitalFiles(models.Model): # Foreign key coopform = models.ForeignKey(CoopForm, on_delete=models.CASCADE) # Attach evidence of share capital attach_share_capital = models.FileField('Attach Share Capital', upload_to="documents", blank=True) this is my forms.py # Update Form class updateCoopForm(forms.ModelForm): nature_registration = forms.ChoiceField(widget=forms.RadioSelect(attrs={'class': 'flex inline-flex', 'cursor': 'pointer'}), choices=CoopForm.REGISTRATION_TYPE) have_bye_laws = forms.ChoiceField(widget=forms.RadioSelect(attrs={'class': 'flex inline-flex', 'cursor': 'pointer'}), choices=CoopForm.BYE_LAWS_CHOICES) attach_bye_laws = forms.FileField(required=False) class Meta: model … -

Django variables from forms to templates
I'm building a website and i'm trying to make the user able to change his credentials. I've made a form for this: newUsername = forms.CharField( label="Enter your new username here*", required=True, widget=forms.TextInput(attrs={ 'class': 'userChangeCredentials', 'value': "{{ user.username }}" })) newEmail = forms.EmailField( label="Enter your new e-mail adress here*", required=True, widget=forms.EmailInput(attrs={ 'class': 'userChangeCredentials', 'value': '{{ user.email }}' })) newPassword = forms.CharField( label="Enter your new password here", required=False, widget=forms.PasswordInput(attrs={ 'class': 'userChangeCredentials', 'value': '' })) passwordConfirmation = forms.CharField( label="Confirm your existing password here*", required=True, max_length=256, widget=forms.PasswordInput(attrs={ 'class': 'userChangeCredentials', 'value': '' })) The problem is, that the values in the widget dictionary are passed as raw text and i want them to be variables. This is the output: Do i need to change something inside of html? My html: <form id="UserForm" action="{% url 'user' name=user.username %}" method="POST"> {% csrf_token %} {{ form|safe }} <input class="userChangeCredentials" type="submit"></input> </form> I tried to make the text raw like this: widget=forms.EmailInput(attrs={ 'class': 'userChangeCredentials', 'value': r'{{ user.email }}' }) But it didn't help.

Django models - how to properly calculate multiple values with various conditions
I want to count multiple metrics in a single query on my model. each metric should have a different filter (or no filters at all) I'm using Django==2.2.3 and a Djongo model. MyModel columns: user_id = models.IntegerField(blank=True, null=True) group_id = models.IntegerField(blank=True, null=True) What i try to run, suggested in another topic, does not work for me. Query: MyModel.objects.aggregate ( total=Count('user_id'), test=Count('user_id', filter=Q(user_id='just_a_fake_id')), group_1_value=Count('user_id', filter=Q(group_id=1)), group_2_value=Count('user_id', filter=Q(group_id=2)), ) The results: {'total': 0, 'test': 47479, 'group_1_value': 47479, 'group_2_value': 47479}, does not make sense - all results (except total) returns the same number which is the count of all the records What i want to run is query similar to SELECT COUNT(user_id) as total, COUNT(CASE WHEN group_id=1 THEN user_id END) as group_1_value, COUNT(CASE WHEN group_id=2 THEN user_id END) as group_2_value FROM MyModel How do i need to modify the query in order to get the correct values? -

Auto populate form field - django
I am trying to auto populate a field in a form so the user does not have the input the data. In this case, the user will start from a show_venue page which is going to display a number of products. By clicking on one of these products, the user is redirected to a product page where a review can be left as part of a form. The form requries the user to select the venue where the review took place. I am looking to simplify this. Since the user already come from a venue_id page, I would like to auto fill this field. I tried different things found in this forum and left my last attempt, which currently deliver the following error message: cannot unpack non-iterable NoneType object. Slight quirk - you will notice the form is actually being saved in the show_venue function and not on the show_product_from_venue function (product page). This is due to a redirection process I had to implement: the user is redirected to the previous venue_ID page after submitting the form: made this happen with a javascript in the template. I am not adding the template page to keep the question concise and dont … -

Django & PostgreSQL- Store Random Numbers in the database
In order to strengthen my basic knowledge in Django, I have decided to create something ther than a "to-do" list, I want to create a app that: "will need to create a number of unique 6 digit codes and store in the database. This will be used to verify unique entries." so my question is as follows: How can I quickly generate and store 50 random entries in my db How can I check if the user has a number that matches or not What is the best way to approach this, I need to start thinking like a dev so I am looking for a bit of guidance and not the result, a nudge in the right direction, I have attached a mock up of the design where the user is requested to submit their "unique entry" and see if it matches to any one of them stored in the db I am obviously reading the official django documentation too, but its not as straight forward for me to understand Regards Trevor -

Can't move validation from view to serializer
I need to move validation from views.py to serializators.py. How can I do it? Validation must check: user can't follow himself user can't follow author that his already follow I have a ViewSet with @action: my view.py: @action( detail=True, methods=['post', 'delete'], permission_classes=(permissions.IsAuthenticated,) ) def subscribe(self, request, id=None): """Following""" author_id = id if request.method == 'POST': author = get_object_or_404(CustomUser, id=author_id) if author == request.user: raise serializers.ValidationError( {'errors': 'You can't follow yourself.'} ) if self.request.user.follower.filter(author=author).exists(): raise serializers.ValidationError( {'errors': 'You already follow this author.'} ) author = get_object_or_404(CustomUser, id=author_id) Follow.objects.create( user=request.user, author=author ) serializer = FollowSerializer(author, context={'request': request}) return Response(serializer.data, status=status.HTTP_201_CREATED) if request.method == 'DELETE': user_id = request.user.id subscribe = get_object_or_404( Follow, user__id=user_id, author__id=author_id ) subscribe.delete() return Response(status=status.HTTP_204_NO_CONTENT) and I have a FollowSerializer in serializers.py my serializers.py class FollowSerializer(serializers.ModelSerializer): class Meta: model = CustomUser fields = ('email', 'id', 'username', 'first_name', 'last_name', 'is_subscribed', 'recipes', 'recipes_count') I try to add a validate method like def validate(self, data): but it doesn't work.
