Django form with repeated fields
I need to a django form with some fields unique (id_station and station name) and the fields: sensor_unity, id_sensor and sensor_name repeated. When form is loaded there are these fields and near the fields sensor_unity, id_sensor and sensor name there is a link to add another row of the same fields.

Get the boolean which values True within a model that contains two (x) booleans
I'm curious if (actually how) my below approach could be simplified. # Model class Vote(models.Model): """ A Class for Votes made by Users for a specific Poller """ poller = models.ForeignKey(Poller, on_delete=models.CASCADE, related_name='vote') user = models.ForeignKey(Account, on_delete=models.CASCADE) created_on = models.DateTimeField(auto_now_add=True) poller_choice_one_vote = models.BooleanField(default=False) poller_choice_two_vote = models.BooleanField(default=False) def __str__(self): return f'Vote by {self.user}' # View @require_POST def submit_comment(request, poller_id): form = PollerCommentForm(request.POST) # Get the choice made by the user of the request user_vote = Vote.objects.get(poller=poller_id, user=request.user) # Check booleans vote_one = False if user_vote.poller_choice_one_vote: vote_one = True [..] Is there a more "django-way" to make this a one-liner to get the field which is True in the view? (e.g. if there would be multiple fields to check. Note: only one will be true) -
How to set a daily id for a model in django
I have a model which people use its id to remember a record for later use. But as the id is getting bigger and bigger, it's getting harder for people to remember that large number. So i thought a short and daily version of that id is needed. That number should start from 1 everyday and having the short id and a date should give the right record. So i thought of adding an AutoField to model and reset it to start from 1 everyday. How can i implement that? If you think it is not the right way to implement that functionality, what do you suggest? -

Get the user instance from a profile model
Hella everyone, Alright I'm building an ecommerce website and stuck at a certain point, I got two models Seller and Product, as follows: class Seller(models.Model): seller = models.OneToOneField(User, on_delete=models.CASCADE) city = models.CharField(max_length=30) country = models.CharField(max_length=30) phone_number = PhoneNumberField() email = models.EmailField(max_length=300) def __str__(self): return self.seller.username class Product(models.Model): STATUS_CHOICES = [ ('New', 'New'), ('New', 'Used'), ] image = models.ImageField(default='dev1.jpg', upload_to='images/') condition = models.CharField(choices=STATUS_CHOICES, max_length=10) seller = models.ForeignKey(Seller, on_delete=models.CASCADE) title = models.CharField(max_length=200) description = models.TextField() price = models.CharField(max_length=15) location = models.CharField(max_length=30) posted_on = models.DateTimeField(auto_now_add=True) def __str__(self): return self.title Now I have a form to save new Product as: class SellProductForm(forms.ModelForm): class Meta: model = Product fields = ('image', 'condition', 'title', 'description', 'price', 'location', ) The problem is in views.py: @login_required def sell(request): form = SellProductForm() if request.method == 'POST': form = SellProductForm(request.POST) if form.is_valid(): print('Ok') instance = form.save(commit=False) instance.seller = request.user instance.save() return redirect('index') context = { 'form': form, } return render(request, 'myapp/sell.html', context) At the end, I get the ERROR: "Product.seller must be a Seller instance." I understand the demand but I can't get myself to imagine the code and come up with a solution, for I'm giving it a User instance not a seller instance. -

Django - implications of READ COMMITTED isolation level in forms for users
So according to Django's doc, by default it implements Postgres' read committed isolation level. I understand the implications wrt to dirty read/writes. However, how does this play out from a user perspective in django? For instance: User A and User B both open the same model form. User A modifies the form, submit it and the commits the transaction, which passes. User B modifies fields "foo" and "bar" for instance. If "bar" has been modified by User A, will the transaction succeed for User B? If "foo" wasn't modified by User A, will the transaction succeed for B? In case a transaction doesn't succeed for B, would be details show up in non_form_errors? Or is the right thing to do is to manage it myself in the view & return a message/redirect to the user according to my business logic? Thanks! -

I have an custom model which name is MyAuthors. If I already have any user in my Abstract user model and save him as author but don't have any objects in MyAuthors model then it will create an objects in MyAuthors model for this user. I tried this code but didn't create user objects in MyAuthors model. class UserManagement(AbstractUser): is_blog_author = models.BooleanField(default=False) is_subscriber = models.BooleanField(default=False) is_customer = models.BooleanField(default=False) class MyAuthors(models.Model): user = models.OneToOneField(UserManagement, on_delete=models.CASCADE, primary_key=True) is_blog_author = models.BooleanField(default=False) @receiver(post_save,sender=settings.AUTH_USER_MODEL) def user_objetcs(sender,instance,created,**kwargs): if created: author = MyAuthors.objects.filter(user=instance) #here I am checking does user have or not any profile in MyAuthors model. if not author: #if user don't have any objects in MyAuthors model then it will create MyAuthors.objects.create(user=instance,is_blog_author=instance.is_blog_authors) -
How to get two RichText features to be mutually exclusive
So basically I've added two custom features for coloring text to a RichTextBlock, and I'd like to make them so selecting one for a portion of text would automatically unselect the other color button, much like it's already the case for h tags. I've searched for a bit but didn't find much, so I guess I could use some help, be it advice, instruction or even code. My features go like this : @hooks.register('register_rich_text_features') def register_redtext_feature(features): feature_name = 'redtext' type_ = 'RED_TEXT' tag = 'span' control = { 'type': type_, 'label': 'Red', 'style': {'color': '#bd003f'}, } features.register_editor_plugin( 'draftail', feature_name, draftail_features.InlineStyleFeature(control) ) db_conversion = { 'from_database_format': {tag: InlineStyleElementHandler(type_)}, 'to_database_format': { 'style_map': { type_: {'element': tag, 'props': {'class': 'text-primary'}} } }, } features.register_converter_rule( 'contentstate', feature_name, db_conversion ) The other one is similar but color is different.
