Displaying label on first form of Django formset only
This is a super straightforward question but I can't seem to find any concise answer it. I have a Django formset that displays different tags associated with an object. Here is the form: class TagForm(forms.Form): def __init__(self, *args, **kwargs): tags = kwargs.pop('tags') super(TagForm, self).__init__(*args, **kwargs) self.fields['tags'] = forms.ChoiceField(choices=[(tag, tag) for tag in tags], label="Tags") I'm rendering the formset using the following code: <li class="list-group-item"> <ul class="list-inline" id="tag-group"> {{ tag_formset.management_form }} {% for tag_form in tag_formset %} <li class="list-inline-item"> {{ tag_form.tags.label_tag }} {{ tag_form.tags }} </li> {% endfor %} </ul> </li> My problem is that this creates a label for each tag. Since this is an inline list, I'd only like to display the label prior to the first tag (and no others). I can't find any straightforward way to do this (without modifying the for loop with explicit logic checking if it is the first form being rendered). I optimistically tried to modify my rendering code to the following: <li class="list-group-item"> <ul class="list-inline" id="tag-group"> {{ tag_formset.management_form }} {{ tag_form.empty_form.label_tag }} {% for tag_form in tag_formset %} <li class="list-inline-item"> {{ tag_form.tags }} </li> {% endfor %} </ul> </li> but this didn't display any labels at all. Is there an idiomatic way … -
Django unrecognized token: "@" while query

Creating a new virtualenv project and creating a virtualenv for existing project causes error
I've tried to search for a solution or a thread handling this problem but I have a hard time expressing it in the first place since I'm fairly new to django, virtualenv, pip etc. I'm using windows 10 and I do everything below in powershell. When I started my first project, named fadderjobb, I didn't use virtualenv. I installed a couple of packages using pip install. Now when I started my second project, wingqvist, I installed virtualenv, made a virtual environment in a folder envs/wingqvist, installed Django and created a new Django project in another new folder webdev/wingqvist. Looking something like this. webdev |-- fadderjobb | `-- projectfiles for fadderjobb |-- wingqvist | `-- projectfiles for wingqvist `-- envs `-- wingqvist `-- virualenv files for wingqvist When I in my virtualenv (wingqvist) tried to run python manage.py migrate in webdev/wingqvist/ i got the following error: (wingqvist) PS C:\Users\Viktor Wingqvist\documents\webdev\wingqvist> python manage.py migrate Traceback (most recent call last): File "manage.py", line 22, in <module> execute_from_command_line(sys.argv) File "C:\Users\Viktor Wingqvist\documents\webdev\envs\wingqvist\lib\site-packages\django\core\management\__init__.py", line 371, in execute_from_command_line utility.execute() File "C:\Users\Viktor Wingqvist\documents\webdev\envs\wingqvist\lib\site-packages\django\core\management\__init__.py", line 347, in execute django.setup() File "C:\Users\Viktor Wingqvist\documents\webdev\envs\wingqvist\lib\site-packages\django\__init__.py", line 24, in setup apps.populate(settings.INSTALLED_APPS) File "C:\Users\Viktor Wingqvist\documents\webdev\envs\wingqvist\lib\site-packages\django\apps\registry.py", line 89, in populate app_config = AppConfig.create(entry) File "C:\Users\Viktor … -

Django get max field value across filtered group of model instances
I need some help creating a custom Django query in my View. I have two models, Department and Team, each Department can have multiple Teams. A user can manually sort the Teams in any order and once done the order field is updated on each Team instance. So, now when a new Team is created I want to get the largest Team.order value within a specific Department. This part below returns all of the Team instances Team.objects.filter(department=team.department.id), but how do I then get the max value from the order field (other than looping)? VIEW class TeamCreate(LoginRequiredMixin, CreateView): model = Team form_class = TeamForm template_name = 'app/sidebar_team.html' # def get_initial(self): def get_initial(self): pk = self.request.GET.get('id') return { 'department': pk, } def post(self, request, *args, **kwargs): form = TeamForm(request.POST) if form.is_valid(): team = form.save(commit=False) team.author = request.user team.modified_date = timezone.now() # Get max Team.order value, increment by one, and set as new team.order max = Team.objects.filter(department=team.department.id).extra(Max('order')) team.save() return redirect('/dashboard/' + str(team.department.id)) else: return redirect('/dashboard/' + str(form.department.id)) -
Address already in use (Errno 98) django with vscode and docker
I have a python application with django and I'm running it inside a docker container. I need to debug this application and every time I do the docker-compose up it gives this error below.

Other than DB setup and connection, Is there any other differences while using MySQL instead of SQLite3 in Django?
Pardon me if I have structured the question wrongly. I am new to Django and I started learning it yesterday. 😅 By difference I mean, like the DB queries. For example for a login/registration in PHP/MySQL, you need to store them and check the credentials via MySQL queries in PHP right? Similarly is there any MySQL specific codes required here? -

TypeError: quote_from_bytes() expected bytes
I'm following this tutorial. When I run test_views.py I have an error that shouldn't be there according the author: TypeError: quote_from_bytes() expected bytes.

Single Input for Multiple Model Formset Instances
I'm trying to figure out how I would go about creating a form that has a single multiplechoicefield with Author's name, exactly 9 empty text fields for Book names, and a single save button. The goal being to select the author once, and add 9 book names to the database. This is relatively straight forward if I use 9 author dropdowns with 9 Book text fields. But how would I go about using a single Author dropdown to populate 9 Book instances? class Author(models.Model): name = models.CharField(max_length=100) def __str__(self): return self.name class Book(models.Model): name = models.CharField(max_length=100) authors = models.ManyToManyField(Author) class BookForm(ModelForm): class Meta: model = Book fields = ['name', 'authors'] def add_two_books(request): BookFormSet = modelformset_factory(Book, form=BookForm, extra=9) formset = BookFormSet(request.POST or None, queryset=Author.objects.none()) -
Periscope plus Django ORM?
I'm working on a Django project that uses Periscope for data visualization. This is all fine and dandy for simple queries but when we get into some of the logic in our ORM, it can get pretty convoluted and brittle to simply hard code a sql query to get what we need visualized. Is there a better way, or at least an automated way to maybe get a succinct QuerySet.query for this purpose? What would be ideal is a way to plug periscope to a higher level like the Model Views. How do you guys solve this problem? -Dash -

Django Social Auth: Google OAuth2 - only display emails from restricted domain list
I have Django Social Auth (pypi package social-auth-app-django) working with Google OAuth2 on a site. When they open a page they get redirected to Google's OAuth2 authentication. This works great, and if they try to log in with an email address that is not in my restricted list they get an AuthForbidden exception. I've added a catch for this and show them a page that they are not allowed to log into this site. All well and good so far. However, I would prefer to not have the invalid email accounts show up at all in the list from Google's authentication page in the first place. I've done this with manual calls to the authentication page before using javascript with a parameter, but I'm not sure how to do so using the canned Django social auth module. Can this be done and if so, how? I have middleware that detects if a user is not logged in and returns a login() view which redirects them to the Google authentication page. views.py # Login using OAuth2. @csrf_protect def login(request): next_page = request.path if next_page is None or next_page == '': next_page = request.POST.get('next', request.GET.get('next', '')) # Check if they are already … -

Integrating existing HTML/CSS/JS with Django project
I'm working on a personal project that involves full-stack development of a Social Networking website. I've build a back-end in Django2.0.5 which supports operations like creating a user, posting content, following other users, etc. While developing this, I tested it by printing information in very minimal HTML pages with no CSS or anything, just data that I can read. Now I'm at a point where I want to start building the front-end. I bought an HTML project from ThemeForest to get started, but now I am completely lost on how to actually integrate the two. The theme is in a GULP project configured to watch for changes, sync with the browser, and recompile the Handlebars templates. So far I've looked into: Converting the Handlebars templates into Django templates, and building the front end in Django. It seems like this method would work, and this is how I started out initially. But, it would take about 10 minutes to convert each of the 100+ pages to a usable Django format before even removing the Lorem Ipsum content Create a new Angular project, add the GULP project into it, and have it communicate with the back-end via REST api This seems like … -

How to retroactively save an extended Django model?
I'm trying to extend a Django model using inheritance. I have a custom model like: from request.models import Request class RequestExtended(Request): start_time = DateTimeField(_('start time'), default=None, db_index=True, blank=True, null=True, editable=False) total_seconds = FloatField(_('total seconds'), default=None, db_index=True, blank=True, null=True, editable=False) def save(self, *args, **kwargs): start_time = get_current_request_start() total_seconds = None if start_time and self.time: total_seconds = (self.time - start_time).total_seconds() self.start_time = start_time self.total_seconds = total_seconds super(RequestExtended, self).save(*args, **kwargs) There's middleware in the request app that automatically saves a new request record for every Django request processed, but this doesn't automatically trigger creation of my extended model. So I tried adding a post_save signal like: def post_request_save(sender, instance, **kwargs): print('request.id:', instance.id, instance.ip) RequestExtended.objects.get_or_create(request_ptr=instance) post_save.connect(post_request_save, sender=Request) However, this throws an error because RequestExtended is ignoring my request_ptr value and trying to instantiate a blank Request instance and not filling in any required fields. How do you create a model extended through inheritance and link it to an existing record that it's supposed to extend? -

In the create exercise I have the next trouble, if I pass the attributes like this: attrs = [ ('objectclass', [b'user', b'top', b'person', b'organizationalPerson']), ('userPassword', [pwd.encode()]), ('displayName', [fullname.encode()]), ('name', fullname.encode()), ('givenName', [names_list[0].encode()]), ('sn', [lastnames_list[0].encode()]),', cn), ('userPrincipalName', userprincipalname),', samaccountname) ] There's no problem and the user is created succesfully but disabled. But, if I pass the parameters like this: attrs = [ ('objectclass', [b'user', b'top', b'person', b'organizationalPerson']), ('userPassword', [pwd.encode()]), ('displayName', [fullname.encode()]), ('name', fullname.encode()), ('givenName', [names_list[0].encode()]), ('sn', [lastnames_list[0].encode()]),', cn), ('userAccountControl', b'512'), ('userPrincipalName', userprincipalname),', samaccountname) ] I get this error on the log: {'info': '0000052D: SvcErr: DSID-031A12D2, problem 5003 (WILL_NOT_PERFORM), data 0\n', 'desc': 'Server is unwilling to perform'} I try with this line too: ('userAccountControl', str(NORMAL_ACCOUNT + DONT_EXPIRE_PASSWORD).encode()), And I get the same error. I try with ldapadd on linux console too and I get the same error. Thanks in advance.
