Pass Factories in Pytest parametrize
I'm trying to pass Factories in my pytest tests but I'm having some difficulty with it. A bit of context -- based on a string, I have some logic which attempts to set a Django model AudioAsset as a foreign key on some models, e.g. a Story or a Song. What I want to test is this logic class AudioAsset(models.Model): ... class Story(models.Model): background_music = ForeignKey(AudioAsset) ... class Song(models.Model): vocals = ForeignKey(AudioAsset) ... I've created a StoryFactory and SongFactory to help me with testing, but I'm having some trouble using pytest.mark.parametrize together with factories @pytest.mark.parametrize( "factory,attribute_name,string", ( (StoryFactory, "background_music", "story-1-background"), (SongFactory, "vocals", "song-2-sound"), ) ) def test_attach_audio_asset(): audio_asset = AudioAssetFactory() model_instance = factory() # Errors here when I try to use a Factory # Trigger the relation update # ... assert getattr(model, attribute_name) == audio_asset I get an error function uses no argument 'factory'. How can I use both factory-boy and pytest together? -

How to pass an argument in django templatetag or call form valid like in the views?
Hi Guys I want to add CreateView to be accessible all my web pages, so I opted for template tags, which bring out the form quite nicely but it can't save. I believe because of the user field which I want to be automatically added before saving the form. in Views.py is quite simple. class BusinessCreate(LoginRequiredMixin, CreateView): model = Business form_class = BusinessAddForm template_name = 'business/form.html' def form_valid(self, form): form.instance.user = self.request.user # this is what i want to add in templatetags messages.success(self.request, 'successfully created your biashara') return super().form_valid(form) this is my form.py class BusinessAddForm(ModelForm): logo = forms.ImageField(label='', required=False, widget=forms.FileInput(attrs={'placeholder': 'your logo'})) description = forms.Field(label='', widget=forms.Textarea(attrs={'placeholder': 'Describe your biashara'})) name = forms.CharField(label='', widget=forms.TextInput(attrs={'placeholder': 'Your biashara name'})) email = forms.EmailField(label='', required=True, widget=forms.TextInput(attrs={'placeholder': 'Email'})) class Meta: model = Business fields = ( 'name', 'logo', 'email', 'description') Now I have a template tag templatetags/business.py from django.template import Library from business.forms import BusinessAddForm register = Library() @register.inclusion_tag('includes/business_form.html', takes_context=True) def get_business_form(): form = BusinessAddForm() return { 'form': form, } which renders the form quite well but doesn't save.

How to add new Foreign Key objects in a Form in Django?
I have a blog that uses Django and currently I am building a page for creating new posts. In my Post model I have a Foreign Key field that is linked to a ImageField. When rendering the page using a generic class view, the field is displayed as a drop-down as expected, but I would like to add new thumbnails, not only selecting the existing ones, similar to the behavior of the admin page when there is a Foreign Key field, where: There is a plus sign next to the drop-down When clicked, shows a pop up where I can upload the image After uploading the image, return to the main page, where the new option is created in the drop-down How can I have a behavior similar to the admin's in my page? I tried to implement it as a widget, but the end result is very messy, as it just redirects to the admin page and I have to go back to my post creation page and reload to show the new option. Alternatively I could just replace the the Foreign Key drop-down with a field to upload a file, but I don't know how, as the foreign … -

Django-filter field not showing after adding lookup expressions - django-filter lib
I'm trying to implement a search field for my website, I decide to use django-filter I was able to create a search field and search the records by typing the exact record name in the search field. (default it provides exact field lookup) And it worked fine. Then I decide to add more field lookup so the search experience improves. But after adding some field lookups the search form field stopped appearing in the template. I go through the documentation couple of times and also tried to google the issue but unable to solve it. Test: By the way, hard cording the field lookups(icontains) to the queryset worked. And also the query set works fine.

Django: use model_formfactory with @property model field

I have installed MongoDB in my Django project. Because is the first time I use Mongo, I decided to try how it works and I created a simple program in order to store data ( price and quantity in my case). The project is called "exchange" and it has 2 folders: exchange and app. This is the file models.py from 'app' folder: from django.db import models from djongo.models.fields import ObjectIdField, Field from django.contrib.auth.models import User class Profile(models.Model): _id = ObjectIdField() user = models.ForeignKey(User, on_delete=models.CASCADE) class Order(models.Model): _id = ObjectIdField() profile = models.ForeignKey(Profile, on_delete=models.CASCADE) datetime = models.DateTimeField(auto_now_add=True) price = models.FloatField() quantity = models.FloatField() #ips = models.Field(default=[]) #subprofiles = models.Field(default={}) This is the file admin.py from django.contrib import admin from .models import * admin.site.register(Profile) admin.site.register(Order) This is how I set the database in the file settings.py of exchange folder DATABASES = { 'default': { 'ENGINE': 'djongo', 'NAME': 'engine', } } So after made the migrations and create the superuser, I run the server, I went in the section Admin, than in Profile, and I created a profile choosing the only option available (my superuser). At this point I created an order in the Orders section: so I chose in the "profile" field … -
Custom fields in user model Django
I am using normal User model in Django to save my users. I would like to add first_name and last_name field, but I don't know how to extend my model and make it work. First and last name should be added in in register form (I use crispy forms). register view if request.method == "POST": form = UserRegisterForm(request.POST) if form.is_valid(): form.save() # save user to database username = form.cleaned_data.get('username') messages.success(request, f"User {username} succesfully created! You can login now!") return redirect('login') else: form = UserRegisterForm() return render(request, 'users/register.html', {'form': form}) register form def __init__(self, *args, **kwargs): super(UserRegisterForm, self).__init__(*args, **kwargs) self.fields['password1'].label = "Hasło" self.fields['password2'].label = "Powtórz hasło" email = forms.EmailField() name = forms.CharField( label="Imię", required=True, max_length=30, ) surname = forms.CharField( label="Nazwisko", required=True, max_length=30, ) class Meta: model = User fields = ['username', 'email', 'password1', 'password2', 'name', 'surname'] labels = { 'username': 'Nazwa użytkownika', } -
How to pass full data as it is without getting converted via GET?
I'm trying to manipulate my form's action via js with the following code: form.action = "{% url 'search.html' phrase='developer' %}" The problem is, it converts my data to weird signs instead of passing it as it is. http://localhost:8000/%7B%%20url%20'search.html'%20phrase='developer'%20%%7D? How can I avoid this convertion ? -
