Why does TinyMCE not remove whitespace after the least element?
I don't get it why TinyMCE editor doesn't remove the blank space after the least element. Is there any default height/length setting that I need to overwrite? This is how it looks in the editor: Which whyever translates to: Source of example posted <div style="width: 100%; height: 0; padding-bottom: 56%; position: relative;"><span style="font-family: 'Varela Round';">Exciting times, exciting times...

Annotate function give me a wrong result
I have set the following three models in my django app: class SubCategory(models.Model): name = models.CharField('Nome della sottocategoria', max_length=30) class Materials(models.Model): subcategory= models.ForeignKey(SubCategory) quantity=models.DecimalField() price=models.DecimalField() class Costs_materials(models.Model): subcategory= models.ForeignKey(SubCategory) quantity=models.DecimalField() In my views I have set the following code: agg=Subcategory.objects.annotate(giacenza=Coalesce(Sum('materials__quantity'), 0)).annotate( utilizzato=Coalesce(Sum('costs_materials__quantity'), 0)) All works perfectly but If I try to add another annotate function, ad example: agg=Subcategory.objects.annotate(giacenza=Coalesce(Sum('materials__quantity'), 0)).annotate( utilizzato=Coalesce(Sum('costs_materials__quantity'), 0)) The result of giacenza and utilizzato are not right, but the result is double than the right. Ad example if the result must be 10, is 20. Where is the error?? -
Set initial value of form field in Django's admin formfield_for_foreignkey
I have following code in my Django admin: def formfield_for_foreignkey(self, db_field, request, **kwargs): if db_field.name == 'affected_user': kwargs['initial'] = request.user.id return super().formfield_for_foreignkey(db_field, request, **kwargs) and affected_user field in the model looks like this: affected_user = models.ForeignKey(User, on_delete=models.CASCADE) What I'd like to get from this is have affected_user assigned particular initial value. Unfortunately, it seems like it doesn't work. Could someone explain why is that? What I know for sure is that is correctly enters this if statement. But doesn't keep my initial value. -
How to add Hyperlink of another serializer in response

How to test uniqueness in a Model.clean() function?
I have a model with a UniqueConstraint: class MyModel(models.Model) name = models.CharField() title = models.CharField() class Meta: constraints = [ models.UniqueConstraint( fields=['name', 'title'], name="unique_name_and_title") ] This works fine and raises an IntegrityError when 2 objects with the same values are created. The problem is UniqueConstraint doesn't present a pretty ValidationError to the user. Usually, I would add these in the Model.clean() class, but if I do this then it will fail on an Update because the instance being updated will already be present: def clean(self): if MyModel.objects.filter(title=self.title, name=self.name): raise ValidationError({'title':'An object with this name+title already exists'}) I How do I create a ValidationError that passes if it's an UPDATE not an INSERT? I know I could do this on a ModelForm and use self.instance to check if the instance already exists, but I want to apply this to the Model class and not have to rely on a ModelForm. -
Object has no attribute on a Textfield in Django
I am getting a 'Sponsor' object has no attribute 'adtag' error, when I try to pull data from a foreign key field in Django. When I try to pull CharField data from the same model, that works perfectly fine. Here are my models: class Sponsor(models.Model): name = models.CharField("Name of Sponsor", max_length=120, blank=False) ... adtag = models.TextField(name="Ad Tag") def __str__(self): return self.name and class Merchant(models.Model): name = models.CharField("Name des Betriebs", max_length=120, blank=False) sponsor = models.ForeignKey(Sponsor, on_delete=models.PROTECT) def __str__(self): return self.name I am calling this by doing this: merchant = Merchant.objects.filter(id=merchant) and print(merchant.sponsor.adtag) And of course the data is filled in in the database + foreign key is associated. Thanks for any recommendation. -
How do I deal with a null query in Django?
So let me start with the registration process in my web page. The user would register first, and then right after registration, he/she is redirected to a page where the user has to input his/her personal info, such as self-introduction, full name, etc. When the user completes filling his/her personal info in, then the user will be redirected to home page. So what I wanted to do is this : When the user tries to access home page, check if he/she is logged in. If yes, check if he/she has filled in the personal info. If no, redirect the user to register page. If the user has filled in (=matching query exists), redirect him/her to the home page. If not, redirect him/her to the personal info page, to fill the fields in. And here's my code in views.py def userHome(request): if request.user.is_authenticated: current_user = request.user if PersonalInfo.objects.get(authuser_id=current_user.id).exists(): context = { 'thisUser' : thisUser, 'newSeed' : newSeed } return render(request, '/userhome.html', context) else: return redirect('/inputpersonalinfo') else: return redirect('/register') models.py from django.db import models from django.contrib.auth.models import User class PersonalInfo(models.Model): objects = models.Manager() authuser = models.OneToOneField(User, on_delete=models.CASCADE, related_name = 'personalinfo', null=True, default=None) name = models.CharField(max_length=50) ...

Django Rest Framework - URL With Query Parameters in Serializer
I have a Story and Post models, where a Post belongs to a Story. I want a URL to get all Posts associated with a given Story. I was able to override the get_queryset of my PostViewSet in order to filter posts by story with URLs like http://localhost:8000/posts/?story=1/. This works beautifully if I type in the URL directly. Now I want to return this kind of url in my StorySerializer. I would like to be able to get Story responses that look like this [ { "url": "http://localhost:8000/stories/1/", "title": "Hero's Journey", "openings": 0, "date_created": "2020-06-28T16:53:35.150630Z", "posts": "http://localhost:8000/posts/?story=1/" }, { "url": "http://localhost:8000/stories/2/", "title": "Halo 3", "openings": 0, "date_created": "2020-06-28T18:17:12.973586Z", "posts": "http://localhost:8000/posts/?story=2/" } ] Is there DRF support for this kind of thing?

Generating QR code and saving the QR code image to AWS S3 in Django Rest Framework
Hi I'am generating QR code using qrcode library in Python. I have setup default storage location for images/files to be uploaded into S3 which is working fine if I am taking an input through API. But in case of generating QR code which is new image is not getting saved to the bucket in S3. Models.py class Item(models.Model): name = models.CharField(max_length=30) qr = models.ImageField(upload_to="asset_tags", null=True, blank=True) image = models.ImageField(upload_to="asset_tags", null=True, blank=True) Generate QR code: def generate_qr(self, qr): qr = qrcode.QRCode( version=1, error_correction=qrcode.constants.ERROR_CORRECT_M, box_size=15, border=5 ) qr.add_data(qr) qr.make(fit=True) img = qr.make_image(fill='black', back_color='white') img.save(qr+".png") Here Image field in models.py is the image which is uploaded by the user which gets saved in bucket. But the qrcode image gets saved in the root of project. I am confused if I need to convert this Pillow image object to django image field and it will get saved to bucket automatically.

ValidationError: ManagementForm is missing while creating update form with ModelFormSet in Django
I have a data adding form which it's been created with BaseModelFormSet. The working logic of my form is as follows: for example, there are 12 attributes in my model class, but the user only uses 8 of them. The users choose this first when they register, then this data adding form is created according to the attributes their chooses. So my forms.py file such as below; class BaseDataFormSet(BaseModelFormSet): def __init__(self, *args, **kwargs): super().__init__(*args, **kwargs) self.queryset = Data.objects.none() and I have created the form in following way; DataFormSet = modelformset_factory(Data, fields=selected_features, formset=BaseDataFormSet) form = DataFormSet(request.POST or None, request.FILES or None) There's no issue while adding a new data but I'm getting trouble when I try to update the exist data. When the user presses the update button, I want the form to be created according to the attributes that the user chooses and to fill the form with the values that the user entered before. So I have created my update form as following; class BaseDataUpdateFormSet(BaseModelFormSet): def __init__(self, *args, **kwargs): super().__init__(*args, **kwargs) and my updateData view; @login_required(login_url = "user:login") def updateData(request,id): features = request.user.profile.selected_features instance = get_object_or_404(Data, id = id) queryset = Data.objects.filter(id = instance.id) DataFormSet = modelformset_factory(Data, fields=features, formset=BaseDataUpdateFormSet) … -
ValidationError ignored in Custom Django Crispy Form
I have a rather complex Django form that affects 3 models and part of which includes an inline formset. I found a nice solution to building the form at https://dev.to/zxenia/django-inline-formsets-with-class-based-views-and-crispy-forms-14o6. I extended that solution and added a third model in a similar way that the formset was added (using a custom Django Crispy Form and inserting it using the Crispy Forms Layout features). My problem is that any validation errors raised on either of the two inserted forms (the formset and the small subform) are simply ignored - the main form posts correctly and raised ValidationErrors are displayed in the form as errors allowing the user to correct any mistakes and its data is correctly saved to the database. If the subform and formset are valid, their data gets saved correctly as well. However, if the data in the subform and formset is not valid, the form never shows the errors to give the user a chance to correct their mistake, and the data is simply ignored and never saved to the database - the main model's data saves fine though. My question is, how do I get the form to refresh with errors displayed in the added subform and … -
