Django Form - Create new entries with multiple foreign k
I have searched a lot about this topic here, but i haven't found the right answer. Here is my problem, i want to create a form(not in admin) where the website users can create new entries, and fill the foreign key for my model Market (who has multiple foreignkey to other models). So in this this form the user can create new entries from the models city, provider and service.(i hope i explain it well) What i try to do is to fill 4 models with a single submit for the user. So far i managed to save one foreign key, using instance with and inlineformset_factory, but i want to know what i have to do in order to write the user input in my 4 models. I want to have only one entry for the models that are related as foreign key, that's why i put extra and max_num at 1 and can_delete as false here is my code, hoping you'll be able to help me.

In django are @transaction.atomic auto applied to nested methods also
I have just started learning django and came across this confusion consider the below code @transaction.atomic def first_method() doing stuff calling_method() def calling_method() items = item.objects.filter(item_id__in=[list of items]) for item in items: item.save() Will the above code save item records one by one in db or will it save all the items at once because I have used @transaction.atomic at the first method? If I have to save all the item records at once in db should I use @transaction.atomic in calling_method() as well? -
Django: put all loop result into one bloc json
Django - Json I've tried many time to get all the result of the loop ['results'][0]['analyzedInstructions'][0]['steps'][steps] (multiple results) in only one bloc. But that does not work.

password field is missing in forms django?
I want to replace username with email in django authentication.So when I was going through documentation it says that If you’re starting a new project, it’s highly recommended to set up a custom user model, even if the default User model is sufficient for you So First I created a custom user model which extends AbstractUser.In which I made username=None and USERNAME_FIELD='email' class User(AbstractUser): username = None first_name = None last_name = None email = models.EmailField(unique=True) USERNAME_FIELD = 'email' REQUIRED_FIELDS = [] Then I created a modelform which uses custom user model.When I render this form in my template, password and confirm password field is missing.I don't know whats going wrong. class UserForm(forms.ModelForm): class Meta: model = get_user_model() fields = ['email'] I thought password and confirm password will be there by default.Am I right? -
How do I plot multiple xy arrays using Chartsjs?
I'm trying to plot to xy arrays using chartsjs x1 = [1,2,3,4,5,6] y1 = [2,4,6,8,10,12] x2 = [4,5,6] y2 = [3,6,9] I can do: var myChart = new Chart(ctx, { type: 'line', data: { datasets: [{ label: 'Scatter Dataset', data: [{ x: 1, y: 2 }, { x: 2, y: 4 }, { x: 3, y: 6 }] { label: 'Scatter Dataset2', data: [{ x: 4, y: 3 }, { x: 5, y: 6 }, { x: 6, y: 9 }] }] }, The problem is that i have a larger x1,y1,x2,y2 array.

How the change the appearance of btn btn-outline-success using Django?
I am struggling with button appearance in Django.

Running collectstatic command from Dockerfile
My goal is to run collectstatic command inside Dockerfile, but when trying to build the image, I run into KeyError messages coming from settings.py file on lines where environmental variables are used, for example: os.environ['CELERY_BROKER'] This is apparently because the container is not yet built, so Docker does not know anything about the environment variables. Is there any command to import all the variables to Docker? Or maybe it's a bad idea to run the collectstatic command inside Dockerfile and it should be run inside docker-compose file ? Or maybe as part of a CI/CD task ? My Dockerfile looks like this: COPY . /app/ WORKDIR /app RUN . .env RUN python manage.py collectstatic --noinput RUN ls -la -

My models: class Location(models.Model): name = models.CharField(max_length=45) class BenefitLocation(models.Model): benefit = models.ForeignKey(Benefit) location = models.ForeignKey(Location) class Benefit(models.Model): locations = models.ManyToManyField(Location, through='BenefitLocation') Here is what Im trying to do in the orm: selected_locations = Location.objects.filter(id__in[1,2]) #Getting IDs from api request matching_benefits = Benefit.objects.filter(locations=selected_locations) In matching_benefits, I only want those with exactly these selected locations. When I try my code, I get this error: django.db.utils.OperationalError: (1242, 'Subquery returns more than 1 row') How can I get the matching_benefits? -
Multivendor Django Ecommerce can it possible?
I'm trying to build a multivendor ecommerce web application like Amazon for example. For this project I used a python with Django, but now I don't know how to create the same page for each supplier, with the ability to each enter their own products and data. I am looking for a tutorial or documentation on this. Can anyone help me ?. Thank you! -
