Django admin not allowing superuser to log in (Custom User Model)
I have created a custom user class which appears to be working correctly however whenever I try to log in to the admin, I keep getting the following error on the login page: Please enter the correct username and password for a staff account. Note that both fields may be case-sensitive. I have already created several superuser which are all saving to the DB correctly with the is_staff/is_superuser/is_active flags set to True as you can see below: CustomUser.objects.all().values() <QuerySet [{'id': 1, 'password': 'test', 'last_login': None, 'is_superuser': True, 'username': 'test1', 'first_name': '', 'last_name': '', 'email': 'test1@test.com', 'is_staff': True, 'is_active': True, 'date_joined': datetime.datetime(2020, 6, 1, 0, 17, 30, 297149, tzinfo=<UTC>), 'role_id': 1, 'user_type_id': 1, 'created_by_id': None, 'update_date': datetime.datetime(2020, 6, 1, 0, 17, 30, 298524, tzinfo=<UTC>), 'updated_by_id': None}]> I am officially puzzled as to what I have done incorrectly...

How to edit user's profile view with django
I am making a form in which the user can edit their profile, so currentley I have 2 forms, one that edits the User model(first_name, Username and Email) and other one that edits the Profile model(biography). The problem is that everytime I edit, just the User model is the one that gets saved while the Profile model doesnt. I think that the error is on the views.py file. views.py def edit_profile(request): if request.method == 'POST': form = EditProfileForm(request.POST, instance=request.user) form1 = UpdateProfileForm(request.POST, instance=request.user) if form.is_valid: form.save() form1.save() return redirect('profile') else: form = EditProfileForm(instance=request.user) form1 = UpdateProfileForm(instance=request.user) args = { 'form': form, 'form1': form1, } return render(request, 'profile-edit.html', args) forms.py class EditProfileForm(UserChangeForm): class Meta: model = User fields = ( 'first_name', 'username', 'email', ) exclude = ('password',) class UpdateProfileForm(forms.ModelForm): class Meta: model = Profile fields = ( 'bio', 'profile_pic', ) exclude = ('user',) models.py class Profile(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) bio = models.CharField(max_length=400, default=1) def __str__(self): return f'{self.user.username} Profile' profile-edit.html (I replaced the {{form.as_p}} and {{ form1.as_p }} to the following html code) <form method="post" enctype="multipart/form-data"> {% csrf_token %} <div class="edit-profile"> <h3>Name</h3> <input type="text" name="first_name" value="{{ user.first_name }}" maxlength="30" id="id_first_name"> <h3>Username</h3> <input type="text" name="username" value="{{ user.username }}" maxlength="150" required="" id="id_username"> <h3>Bio</h3> … -
How do I get my Django context variables into my JS file?
I'm trying to get data from a Django Backend to display on a map with Google Maps API, but I can't figure out how to pass the variables into the Javascript.

slice requires 2 arguments, 1 provided
I'm trying to add some values from another list synchronously in the for loop of django ’s template. When I use a given number everything works fine, but when I replace it to {{forloop.counter}} it reports an error slice requires 2 arguments, 1 provided I Googled it and the suggestion is that there should be no spaces in the code, but there are no spaces in my code, here the code in question. {% for i in invtypes %} <li> ... <p>{{data|slice:":{{forloop.counter}}"}}</p> </li> {% endfor %} The {{data}} is a list of extra data for invtypes so they have same length and sort。 -
Django: How to use javascript variable in url template tag
I want to use a javascript variable as the pk for my django url template tag. It has been asked before, but none of the solutions work for me. See for example Get javascript variable's value in Django url template tag. I tried the solution suggested by @Mike Lee, i.e.: var url_mask = "{% url 'someview' arg1=12345 %}".replace(/12345/, var.toString()); However, when I try this, it redirects to /12345, in other words the replacement is not made. A bit of context of what I am trying to do: I have flashcards. Studying flashcards is done via javascript. In my js file, there are variables to get the necessary cards, show the current card etc. I have a button in my html that is supposed to redirect to a page where you can edit the flashcard. So for example, I have: <a id="button" class="btn btn-default btn-warning" id='button-study' href="{% url 'flash:edit' card.id %}">Edit</a> card.id is just a placeholder - I need this to refer to whichever card is showing at any given time. When studying, when I look at the console, I can see the details of the current card, including the id, which is what I need to put in the url … -
Show different requests in different endpoints in Swagger (DJANGO)
I have 4 requests A,B,C and D defined in urls.py What I want to accomplish is -> I want A and B to be seen in the swagger form that can be accessed with url mydomain/firstapi and C and D to be seen in the swagger form that can be accessed with mydomain/secondapi. But what ends up happening is that both of these urls show the same swagger form. Requests A and B are listed below firstapi and request C and D are listed below secondapi as expected (but both of these groups can be seen in both urls which is precisely what I wanted to avoid) What I have tried is #urls.py firstapipatterns= ([ path('a', AView.as_view()), path('b', BView.as_view()), ], 'secondapi') secondapipatterns= ([ path('c', CView.as_view()), path('d', DView.as_view()), ], 'secondapi') urlpatterns = [ path('firstapi/', include(firstapipatterns)), path('secondapi/', include(secondapipatterns)), ] -

Custom font on simple html website will not load
I have been following code and examples online to try and use a custom font on my very basic html website. If it matters, I am using django. Files of note: aurebesh_translator.html <!DOCTYPE html> <html> <link rel="stylesheet" type="text/css" href="main.css"> <p>This should be in aurebesh</p> </html> main.css @font-face { font-family: "aurebesh"; src: url(aurebesh.ttf); font-style: normal; font-weight: 100; } p { font-family: aurebesh; font-weight: 100; } These are arranged as follows: | templates | - ... | - main.css | - aurebesh_translator.html | - fonts | -- aurebesh.ttf ... where the aurebesh.ttf file is the associated font file for the font I want to use. From what I can tell online, this seems to be the way it is supposed to be formatted to use my custom font. The weird thing is, if I just copy the above files to my desktop (so that only main.css, aurebesh_translator.html, and fonts/aurebesh.ttf are present) and run the aurebesh_translator.html in a browser, it loads and uses the font successfully! This is super weird to me, because when I include these files in the context of the rest of my website's files, it somehow stops working! I have tried opening it in chrome as well as firefox … -

Edit saved embedded youtube video height and width using django ckeditor
I have been successful in embedding Youtube video in Django admin using django ckeditor. The problem is, if I have saved a Youtube video and set a certain height and width of the embedded video, I can't seem to be able to edit the width and height. The only way I can do it is by deleting the old embedded video and add a new one which is not ideal. Is there a way to do this without re-embedding this video? My ckeditor configs in settings.py: CKEDITOR_CONFIGS = { 'default': { 'height': 800, 'width': 1200, 'toolbar_Full': [ ['Styles', 'Format', 'Bold', 'Italic', 'Underline', 'Strike', 'SpellChecker', 'Undo', 'Redo'], ['Link', 'Unlink', 'Anchor'], ['Image', 'Flash', 'Table', 'HorizontalRule'], ['TextColor', 'BGColor'], ['Smiley', 'SpecialChar'], ['Source'], ['CodeSnippet'], ['Youtube'], ['JustifyLeft', 'JustifyCenter', 'JustifyRight', 'JustifyBlock'], ['NumberedList', 'BulletedList'], ['Indent', 'Outdent'], ['Maximize'], ], 'extraPlugins': 'justify, liststyle, indent, codesnippet, youtube', # this setting is needed so that you can see the embedded ytv # once saved in the editor 'allowedContent': True, 'removePlugins': 'iframe', } } -

Django send data to Javascript File

How to use TextField from Django in JavaScript?
I have a Django model: class MyModel(models.Model): charField = models.CharField(maxLength=200) textField = models.TextField() and an HTML template with a JS function that displays charField and textField like this: document.getElementById("someElement").innerHTML = "{{ myObject.charField }}"; document.getElementById("someOtherElement").innerHTML = "{{ myObject.textField }}"; The former works fine, but the latter doesn't. I assume the problem is the fact that it is a TextField because there is no other difference between the two. How can I fix this? -
Django: how to generate activate_url that Django allauth generates for email confirmation
Django allauth sends an account confirmation email with activate url which is {{activate_url}}. One example for this url is http://127.0.0.1:8000/accounts/confirm-email/NTM:1jfPhE:KyDCaadIYlHM23UbccSVcDnzdJU/. But I can't use allauth to handle for sending confirmation emails as I am using Gmail account for sending emails and Gmail is not allowing to send email with allauth because it was not secure enough. So I used Gmail API to send emails and using @receiver(user_signed_up) to send confirmation emails. But I want to allauth to handle the activation process and I see that allauth uses {{activate_url}} link for verifying the email for the account. How do I generate this {{activate_url}} so that I send the email with this link and allauth handles confirming email from there? -
