Passing context variable from template to JavaScript file
This thread here discussed using variables in inline JavaScript in templates. If I have a separate .js files containing scripts, sitting in static folder, such as following: utils.js const createButton = (buttonCount) => { containerId = "myContainerId" container = document.getElementById(containerId) for (var i = 0; i < buttonCount; i++) {} newButton = document.createElement("button") newButton.value = "Test" newButton.id = "testButton" + i container.appendChild(newButton) } } createButton(buttonCount) mytemplate.html {% extends "base.html" %} {% load static %} {% block title %}Testpage{% endblock %} {% block content-main %} <link href="{% static "css/mycss.css" %}" rel="stylesheet"> <link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/bulma/0.4.0/css/bulma.css" /> <div id="myContainerId"></div> <script src="{% static 'js/utils.js' %}"> </script> {% endblock %} If I have a variable buttonCount passed into this template via a view function's context, how do I pass it to the utils.js file to be called by function createButton()? views.py def button_view(request): ... buttonCount = 5 return render(request, 'mytemplate.html', {'buttonCount': buttonCount}) -
Catch-all view break URL patterns in Django
def get_urls(self): urls = super().get_urls() url_patterns = [path("admin_profile", self.admin_view(self.profile_view))] return urls + url_patterns The above method cause the catch-all view to break URL patterns which I route after the admin URLs and cause the following error/exception: Page not found (404) Request Method: GET Request URL: http://127.0.0.1:8000/admin/admin_profile/ Raised by: django.contrib.admin.sites.catch_all_view But this only happen when final_catch_all_view = True in django.contrib.admin.sites.catch_all_view When setting final_catch_all_view = False No error or exception is made, everything went fine. Now my question is how can make the function work when final_catch_all_view = True And this is what docs say about catch_all view: > The new admin catch-all view will break URL patterns routed after the > admin URLs and matching the admin URL prefix. You can either adjust > your URL ordering or, if necessary, set AdminSite.final_catch_all_view > to False, disabling the catch-all view. See What’s new in Django 3.2 > for more details. -

Getting a "'str' object has no attribute 'get'" error in Django Python
Some context: I am trying to create an email verification system in Django. I have already made the register/sign-in/log-out views and they work but I have added the verification system to them. I am getting the error after submitting the registration form. I think that the error is happening after the form submission where I am sending the email. The error I am getting is: 'str' object has no attribute 'get' Here is the relevant code: Views: def register(request): if request.method == 'POST': form = CreateUserForm(request.POST) if form.is_valid(): inst = form.save() uidb64 = urlsafe_base64_encode(force_bytes(inst.id)) domain = get_current_site(request).domain link = reverse('verify_email', kwargs={'uidb64': uidb64, 'token': token_generator.make_token(inst)}) activate_url = 'http://' + domain + link print(activate_url) #prints the correct link email_subject = 'Verify Your Email' email_body = 'Hello ' + inst.username + '\nClick the link to verify your email\n' + activate_url email = EmailMessage( email_subject, email_body, settings.EMAIL_HOST_USER, [inst.email], ) return reverse('verify_email_intro', kwargs={'user_id': inst.id}) else: form = CreateUserForm() return render(request, 'users/register.html', {'title_page': 'Register', 'form': form}) @csrf_exempt def verify_email_intro(request, user_id): context = { 'user_id': user_id, } return render(request, 'users/verify_email.html', context) def verify_email(request, uidb64, token): try: pk = force_text(urlsafe_base64_decode(uidb64)) user = User.objects.get(id=pk) if user.is_active: return redirect('login') else: user.is_active = True user.save() except Exception as ex: pass return … -
Django many to many serializers circular dependency work around?
I have two models, publications and articles, that are connected to each other by a ManyToManyField. Models shown below class Article(models.Model): headline = models.CharField(max_length=100) publications = models.ManyToManyField('Publication') class Publication(models.Model): title = models.CharField(max_length=30) I want to reference articles to publication and publications to articles in both model serializers. class PublicationSerializer(serializers.ModelSerializer): title = serializers.CharField() articles = ??? class Meta: model = Publication fields = ['title', 'articles'] class ArticleSerializer(serializers.ModelSerializer): headline = serializers.CharField() publications = PublicationSerializer(many=True) class Meta: model = Article fields = ['headline', 'publications'] I have been looking up various solutions, many refer to using Relational Fields, such as StringRelatedField, and saw a different solution using SerializerMethodField(), but there doesn't appear to be much documentation on them. Any examples or solutions to this issue? -
Adding custom QuerySet to UserModel causes makemigrations exception
I would like to create a custom queryset for my User model. However, I cannot simply use objects = UserQuerySet.as_manager() since the standard Django User model already has a custom UserManager.

Can saving a model fail after pre_save?
I have a pre_save signal set up for my User model that does something before a User is saved. My question is, will a User.save() function ever fail after the pre_save has already been executed? Basically I'm doing something in the pre_save that I wouldn't want to do if the User.save() fails. Should I be worried about this corner case? NOTE: I cannot use post_save because I need the pre_save instance object. -

Django: Call a function in views.py on HTML form submit
I am building a geospatial web app and am currently trying to implement a date form input to display data from different dates. Each data point is an Object stored in the database, and my frontend uses OpenLayers in javascript. Data is passed from views.py to javascript as a geojson file. Since it's a map, I would effectively like everything to stay in the same view and URL (asides from some GET parameters in the URL). The flow that I'm thinking of goes like: 'Submit' button is clicked on GET form Function in views.py (or somewhere else) is called with parameters from the GET form A query is made to the database to filter by date, and creates a geojson file of the points Geojson is given to javascript to display All the posts I've seen about this problem include calling a different view, can I do all this in the same view? Thank you! -

Django form working with bound and unbound form
In django I have the following form for a toy wikipedia website, used when a page is created class WikiSubmitForm(forms.Form): Title = forms.CharField(max_length=200, widget=forms.TextInput(attrs={'placeholder': "Title of wiki page"}), label="") Body = forms.CharField(widget=forms.Textarea(attrs={'placeholder': "Content of wiki page"}), label="") When I allow a user to edit a page, I want to set an input value, so that the initial Body variable in the form is set to the actual content on the page. Confusingly, if I use: form = WikiSubmitForm(initial = {'Title': Title, 'Body': mkdown_file}) The form is created with the preset values, but it looks different to the form as on the create page part of the website, despite them using the same form (see picture at bottom), whereas if I do what I did on the create page but add initial values form = WikiSubmitForm(request.POST, initial = {'Title': Title, 'Body': mkdown_file}) It looks normal, but the initial values don't load. This seems to be because the form is now 'bound'. I found a workaround solution, but out of curiosity was wondering (1) Is there a way to fix the different look of the form when request.POST isn't passed in as an argument (2) Is there a way to pass in … -
