How to fix Cannot assign "": "" must be a "" instance? when it is created in view?
I want to create model with view when the user is created, but I got and error: Cannot assign "<User:test1234": "Customer_info.customer" must be a "Customer" instance. Here are the models that I have and which I want to be created automatically when user is registered. class Customer(models.Model): user = models.OneToOneField(User, null=True, on_delete=models.CASCADE) points = models.FloatField(default = 0.0) ... class Customer_info(models.Model): customer = models.OneToOneField(Customer, on_delete=models.CASCADE) deposit = models.FloatField(default = 0.0) And in views.py after registering those models are creating def reg(request): form = CreateUserForm() if "register-btn" in request.POST: form = CreateUserForm(request.POST) if form.is_valid(): new_user = form.save() login(request, new_user) Customer.objects.create( user=new_user, points=0.0 ) Customer_info.objects.create( customer = new_user, deposit = 0.0 ) response = redirect('profile') return response return render(request, 'main.html') -
Making website responsive to devices other than desktop pc
I've been tasked to try and make my friend a portfolio website(my real first project). I think I've made a mistake of only focusing on designing for desktop and forgetting about other devices. Here's a link to the site so you can see how it is responding; https://vsworldtest.herokuapp.com/ As you can see its not responding as I would like it when loading on a mobile phone. Still some tweaks needed and some cleaning of the css for desktop but it is more than viable for testing at the moment. If you have any idea of what I could do to make this responsive for mobile devices and tablets please share with me.

How do you create a function to check the attribute of another field in a separate model?
class Trait(models.Model): name = models.CharField(max_length=20) animal_types = models.ManyToManyField(AnimalType) # slots = models.CharField(default=None, null=True, max_length=4) #slots is meant to hold a value that determines where it can be placed in animal model #i.e. null means anywhere, "2" means only trait 2 #def TraitPlace(self): def __str__(self): return self.name #need to add animal details like age and gender to a separate model or integrate/hardcode into animal model as they're only 7 options class ANIMAL(models.Model): animal_type = models.ForeignKey(AnimalType, on_delete = models.CASCADE) first_trait = models.ForeignKey(Trait, on_delete = models.CASCADE) #first trait and animal required as animals always exist and have at least one trait # second_trait= models.ForeignKey(Trait, on_delete = models.CASCADE) # third_trait= models.ForeignKey(Trait, on_delete=models.CASCADE) I've got an animal model which is used to create an animal with up to 3 traits, the problem is that some traits have specific placement restrictions, i.e. "lithe" can only be in position 3, and glistening can only be in positions 2 and 3. It was suggested to add an additional "slots" field under the trait model. I understand logically how it's supposed to work out, but am struggling with implementation. I tried to look up documentation and use hasattr under my first_trait but that didn't work or I just didn't … -
How can I show payment update for a specific appointment?

Django forms template dropdown with unique identifier for each iteration of a forloop
I am trying to generate a unique ID for each iteration of a for loop item. The item generated is a drop down menu and the number of times it s generated will depend on the number of incidents that are active. The the problem I am having is that the ID of the dropdown is the same for each dropdown menu. In this case id="id_status" when viewed via the browser page source Is there a way to generate for example id="id_status_1" for the first dropdown, then id="id_status_2" for the second one and so on? I tried to implement something with forloop.counter and also javascript's setAttribute("id", "uniqueIdentifier"), but have been racking my brain for hours now without success models.py from django.db import models ... ... class IncidentStatus(models.Model): status = models.CharField(max_length=128) def __str__(self): return self.status forms.py: from .models import IncidentStatus ... ... class IncidentStatusAssigneeForm(ModelForm): status = forms.ModelChoiceField(queryset=IncidentStatus.objects.all().order_by('status'), empty_label='Select a Status', label='') class Meta: model = IncidentStatus fields = ('status',) views.py: from .models import IncidentStatus from .forms import IncidentStatusAssigneeForm ... ... def set_status(req): all_statuses_a = IncidentStatusAssigneeForm() all_incidents = Incident.objects.all ... ... context = {'all_statuses_a': all_statuses_a, 'all_incidents': all_incidents, ....} return render(req, 'incident_main/assignee.html', context) template.html: {% for incident in all_incidents %} {{ all_statuses_a }} … -

VSCode Django HTML, JS, CSS guide for proper autocomplete and linting

Attach, display and submit forms to each product id displayed within a for loop (Django)
I am looking to integrate a form to each product, included within a loop. Each form is independent for the others: if one form is submitted, the others wont need to be. Currently the form is not validating. I think it's because I haven't managed to attach the form to the specific product id and I am not sure how to do that. When applying a form to a specific Id on a single page, I would simply proceed with def function(request, product_id). This is not an option here, as I am displaying several products on the same page. models.py class ReviewRating(models.Model): user = models.ForeignKey(User,blank=True, on_delete=models.CASCADE, related_name="usercomments") product=models.ForeignKey(Product,related_name="comments", on_delete=models.CASCADE) review =models.TextField(max_length=250, blank=True) rating =models.IntegerField(choices=RATING, default=0) forms.py class ReviewForm(forms.ModelForm): venue = forms.ModelChoiceField(queryset = Venue.objects.all(),required=False) class Meta: model = ReviewRating fields = ['review', 'rating','venue'] widgets = { 'venue': forms.TextInput(attrs={'class':'form-select', 'placeholder':'Enter name'}), } views.py def show_event(request, event_id): submitted = False form = '' form = 'ReviewForm' if request.method =="POST": form = ReviewForm(request.POST) if form .is_valid(): data = form .save(commit=False) data.product_id = product_id #<-- How do I define product_id? data.user_id = request.user.id data.save() else : print(form .errors) else: form = ReviewForm() event = Event.objects.get(pk=event_id) categories = Product.objects.filter(event=event_id) menu = event.product.filter(event=event_id) return render(request, 'main/show_event.html',{'event':event, 'categories':categories,'menu':menu,'form':form,'submitted':submitted}) … -

Implementing django-recaptcha in Django project with a custom user and django-allauth
I need help implementing django-recapcha in a Django project that has a custom user and also has django-allauth. When I first set up this project I set up a custom user, as it is the recommendation from the official Django site.(https://docs.djangoproject.com/en/4.0/topics/auth/customizing/#using-a-custom-user-model-when-starting-a-project). After that I implemented django-allauth for authentication. Now I want to implement django-recapctha and I haven't found the right way to do it. I don't know how I should configure the forms.py file, because I don't understand well what is happening with this combination of custom user and django-allauth. Which is the form I should edit to configure django-recapcha and from which app? When I configured the custom user I did it as follows: I created an app called accounts. I created accounts/models.py with the following code: from django.contrib.auth.models import AbstractUser from django.db import models class CustomUser(AbstractUser): profile_pic = models.ImageField(default='default.jpg', upload_to='profile_pics') I created accounts/forms.py with the following code: from django.contrib.auth import get_user_model from django.contrib.auth.forms import UserCreationForm, UserChangeForm class CustomUserCreationForm(UserCreationForm): class Meta: model = get_user_model() fields = ( 'email', 'username', ) class CustomUserChangeForm(UserChangeForm): class Meta: model = get_user_model() fields = ( 'email', 'username', ) Then I added the following to settings.py: AUTH_USER_MODEL = 'accounts.CustomUser' The django-recaptcha instructions indicate that I … -

Nextcloud and Django (static) website aside behind nginx-proxy issue
First of all, i'm a beginner in networking and with web services in general. Context : i've a domain name : mydomain.com and a VPS server (with Ubuntu) with a fixed IPV4 adress : MYIPADRESS. In my VPS provider control panel , i've binded mydomain.com to MYVPSIPADRESS with an entry A. Only one domain is binded to MYIPADRESS. Objective : I want to host two webservices on my VPS : a nextcloud instance and my blog that is a Django static website, all set up with HTTPS. I want that my nextcloud instance points to cloud.mydomain.com and my blog Django instance to blog.mydomain.com. To do so, i'm using docker. Basically, i'm using the nginx-proxy server + its letsencrypt companion. Once done, i run my docker container for my django blog with env variables according to nginx-proxy documentation and put my blog container in the same network as nginx-proxy and its letsencrypt companion networks. At each time, without detaching my images , logs do not show me any warnings/"exited with 1"/red-written rows stuffs whether with blog container or nginx-proxy/letsencrypt companion container. I did not try to put my nextcloud instance so far since just my blog container setup does not work. … -

Django 3.0 admin searching for different models fields

I want to save the changes of model's views field but everytime I save it, it sets the new value to updated_at field. It means everytime I refresh the page it shows the current time on updated_at field, which is very bad. I have changed my view's code to: ... def get(self, *args, **kwargs): Announcement.objects.filter(id=kwargs['id']).update(views=F('views') + 1) return super().get(self, *args, **kwargs) Now it works fine but I have several questions. How it saves the new value of views field without calling the save method of """"Django"""""? How far can I go with it. What is the best practices of changing some fields of model without hitting the save method? Thanks in advance for broad explanation!
