Django load wrong template
I am new to Django. I am trying to configure an app called 'faq', and an index page to display the different "apps", including the previous one. I was following the Learn Django site guide to decide what was best for the template structure. So, I configured myproject/settings.py to let load the template from templates folder: 'DIRS': ['templates'],. In the app folder myproject/apps/faq I have created a templates folder. In the app views myproject/apps/faq/views.py I defined the views to load the data from database and send it back to the template: from django.shortcuts import render from .models import * def faqs_view(request): faqs = FrequentAskedQuestion.objects.all() context = { 'faqs': faqs } return render(request, 'index.html', context) def faq_view(request, id): faq = FrequentAskedQuestion.objects.get(id=id) print(faq) context = { 'faq': faq } return render(request, 'detail.html', context) In the app folder I have created a URLconf configuration in myproject/apps/faq/urls.py: from django.urls import path from .views import faqs_view, faq_view urlpatterns = [ path('', faqs_view, name='faq-list'), path('<int:id>', faq_view, name='faq-detail'), ] A parenthesis here, since the first attempt I have tried to create a project templates folder and use the project views.py and urls.pyand it didn't work I decided to create another app called main.

celery task scheduled differently?
I have a scheduled Celery task that fetches some data via an API, every 30 min. However, if it crashes or there's no new data, I want the task to retry 5 more times and then stop completely, i.e.(it shouldn't execute after every 30 min anymore). My code is as follows: @app.task(autoretry_for=(Exception,), retry_kwargs={'max_retries': 5}, retry_backoff=True) def my_func(): print('retrying') try: # do something print('i update') except Exception as exc: print("i don't update") celery conf: app.conf.beat_schedule = { 'my_func': { 'task': 'app.tasks.my_func', 'schedule': 1800.0 }, } I notice that the task does not stop execution after 30 min.

Manually set model fields in ModelForm
I have a model with a foreign key and a unique constraint as follows: class Menu(models.Model): tournament = models.ForeignKey(Tournament, on_delete=models.CASCADE) name = models.CharField(max_length=128) date_menu = models.DateField() class Meta: constraints = [ models.UniqueConstraint(fields=['tournament', 'name', 'date_menu'], name="unique_name_menu") ] I would like to create a form to add instance of Menu. However the value of tournament is set by the URL of the page. I do not want the user to be able to set it. For this I use a modelForm, excluding the tournament field : class MenuForm(forms.ModelForm): date_menu = forms.DateField(initial=datetime.datetime.now()) class Meta: model = Menu exclude = ['tournament'] Here is my view : def add_menu(request, tournament_slug): tournament = get_object_or_404(Tournament, slug=tournament_slug) form = MenuForm(request.POST or None) if form.is_valid() and formset.is_valid(): menu_id = form.save(commit=False) menu_id.tournament = Tournament.objects.get(pk=1) menu_id.save() # I get the integrity error only here return HttpResponseRedirect(reverse('admin')) return render(request, "view.html", {'form': form, 'formset': formset, "tournament": tournament}) My problem is that when I call the .is_valid() function on this form the uniqueness condition cannot be checked as the tournament field is not set. As a result I get an integrity error when calling the save function in the view. The question is : how can link the Menu instance created by the form … -

When a new model object is create, populate one of the values
I have tried this a few ways but am stuck and unsure where to go. My model (ExampleModStack) has a toadd_fk which is a foreign key obtained from a API. I want to use this to create a forign key refernce to the Toadd model when the ExampleModStack is created. I create ExampleModStack model by reading the API values so I need a funciton to do this for me. I was thinking of using signals pre_save function so that I can set the toadd relationship there. Here is my code: class ExampleModStack(models.Model): toadd_fk = models.IntegerField() toadd = models.ForeignKey( Toadd, null=True, on_delete=models.CASCADE, related_name='%(class)s_toadd' ) class Meta: verbose_name = 'example_mod_stack' verbose_name_plural = 'example_mods_stack' def __str__(self): return str(self.id) @receiver(pre_save) def referenc_product(cls, instance, **kwargs): cls.toadd = Product.objects.get(id=cls.toadd_fk) I can not get this to work though.

ImageField uploads with Django Admin but not with template
I have the following form hooked to my Django Admin: # forms.py class ProfileForm(ModelForm): class Meta: model = UserProfile fields = ('name', 'profile_pic') # admin.py class ProfileAdmin(ModelAdmin): form = ProfileForm admin.site.register(UserProfile, ProfileAdmin) # models.py class UserProfile(models.Model): user = models.OneToOneField(CustomUser, null=True, on_delete=models.CASCADE) name = models.CharField(max_length=200, null=True) profile_pic = models.ImageField(upload_to='profile_image', null=True, blank=True) def __str__(self): return str(self.user) Now if I upload the profile_pic with Django Admin, everything works fine. However, if I submit the image through my template, it doesn't work. Here's my template: {% extends '_base.html' %} {% block content %} <form action="." enctype="multipart/form-data" id="userprofile_form" method="post" novalidate=""> <h1> Update your profile </h1> {% csrf_token %} <div> {{ form }} <button class="border-2">Update Profile</button> </form> {% endblock %} The corresponding view is this: @login_required def get_profile(request): profile = request.user.userprofile form = ProfileForm(instance=profile) if request.method == 'POST': form = ProfileForm(request.POST, request.FILES) if form.is_valid(): form.save() return render(request, 'profile-edit.html', {'form':form}) In the view (inside if form.is_valid()), form.cleaned_data has value None for profile_pic. request.FILES is <MultiValueDict: {'profile_pic': [<InMemoryUploadedFile: dave_pic.png (image/png)>]}> What's wrong with my upload logic. As I said, the same works just fine with Django Admin. MEDIA_ROOT and MEDIA_URL are all set. -

How to deploy a Vue.js App + Django Database to Heroku?
I created a Vue.js App with a Django Database. The Vue.js App is running with router and webpack-bundle. I want to deploy that App to Heroku, so I can access it from there. When I separately deploy them to Heroku it works, but not together in one combined app. My folder structure looks like that: core/ ├─ views.py ├─ __init__.py frontend/ ├─ node_modules/ ├─ public/ │ ├─ favicon.ico │ ├─ index.html ├─ src/ │ ├─ views/ │ ├─ App.vue │ ├─ main.js │ ├─ router.js ├─ .gitignore ├─ package.json ├─ README.md ├─ vue.config.js ├─ webpack-stats.json my-app-products/ ├─ api/ ├─ admin.py ├─ apps.py ├─ models.py ├─ views.py my-app-shop/ ├─ asgi.py ├─ settings.py ├─ urls.py ├─ wsgi.py ├─ __init__.py The main problem I encounter is, that the vue app is in a subdirectory and I don't know how to deploy two apps in Heroku. If that is even possible, to deploy two apps in one project. I have knowledge on using git and on changing the heroku buildpack. Thanks in advance -
How dowload image from url to this custom ImageField(JsonField) Django
I have custom model_field in Project.
