Django - How to get image field of ForeignKey query elements?
I have the following code at views.py to sort TvShows by there latest released episode (release_date) within 90 days: def tv_show_by_set_just_released(request): latest_episodes = TvShows.objects.filter(episode_show_relation__release_date__gte=now() - datetime.timedelta(days=90)) ... For each element found, I now also want to display a cover. But the cover is located at a different table and I don't really know how to pull it out probably in this query context. In the end I want to display the very first TvShowSeasons.cover for each element of my query from above. Is it somehow possible to marry these two elements, latest_episodes and TvShowSeasons.cover to display them properly at a template? Please also see models.py class TvShows(models.Model): objects = RandomManager() id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False) title = models.TextField(verbose_name=_("Title"), blank=False, null=True, editable=False, max_length=255) genre_relation = models.ManyToManyField(through='GenreTvShow', to='Genre') date_added = models.DateTimeField(auto_now_add=True, blank=True, verbose_name=_("Date Added")) class TvShowSeasons(models.Model): objects = RandomManager() id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False) show = models.ForeignKey(TvShows, on_delete=models.CASCADE, related_name='season_show_relation') season_number = models.IntegerField(verbose_name=_("Season Number"), blank=True, null=True, editable=False) cover = models.ImageField(verbose_name=_("Cover"), blank=True, null=True, upload_to=get_file_path_images) cover_tn = models.ImageField(verbose_name=_("Cover Thumbnail"), blank=True, null=True, upload_to=get_file_path_images) total_tracks = models.IntegerField(verbose_name=_("Total Tracks #"), blank=True, null=True) rating = models.CharField(verbose_name=_("Rating"), blank=True, null=True, editable=False, max_length=255) copyright = models.TextField(verbose_name=_("Copyright"), blank=True, null=True, editable=False, max_length=255) date_added = models.DateTimeField(auto_now_add=True, blank=True, verbose_name=_("Date Added")) Thanks in advance -
Problem with Django Tests and Trigram Similarity
I have a Django application that executes a full-text-search on a database. The view that executes this query is my search_view (I'm ommiting some parts for the sake of simplicity). It just retrieve the results of the search on my Post model and send to the template: def search_view(request): posts = m.Post.objects.all() query = request.GET.get('q') search_query = SearchQuery(query, config='english') qs = Post.objects.annotate( rank=SearchRank(F('vector_column'), search_query) + TrigramSimilarity('post_title', query) ).filter(rank__gte=0.15).order_by('-rank'), 15 ) context = { results = qs } return render(request, 'core/search.html', context) The application is working just fine. The problem is with a test I created. Here is my tests.py: class SearchViewTests(TestCase): def test_search_without_results(self): """ If the user's query did not retrieve anything show him a message informing that """ response = self.client.get(reverse('core:search') + '?q=eksjeispowjskdjies') self.assertEqual(response.status_code, 200) self.assertContains(response.content, "We didn\'t find anything on our database.

How to generate dynamic rows in page based on the response of the js request? (Django Template / HTML)
Is this possible to append the rows with data in an HTML table as a response of the JavaScript request without doing a page postback? Django: 3.1.7 I want to write a seprate HTML file (Like a file we can use with include tag) for the code so I don't have to append the html of entire table in the HTML string.

Final Test: Set up Django app for production
I finalized my first django app and uploaded it to the webhosting service and I'm having trouble with that. However, I am not sure that I did not make any mistake setting it up before the upload. So my question is: Can I run my virenv locally again and should my django app still work locally? I try to locate where my mistake is and want to make sure, that it is set up correctly. If I run my virenv I get this error "This site can’t provide a secure connection". Any help? That would be great! -

Rendering database objects in Django
This is a basic question but I can't figure out what I'm doing wrong... I'm trying to render a detail view in my django site, but my calls to get the object are just failing or else not rendering. Here is what I have: views.py from django.template import loader from django.views.generic.base import TemplateView from django.http import HttpResponse from .models import user_profile def detail(request, content_id): template = loader.get_template('profiles/detail.html') profile = user_profile.objects.get(pk=content_id) context = {'profile': profile} return HttpResponse(template.render(context, request)) Within the template, I have simply been testing the calls using: <h1>{{ profile }}</h1> <h1>{{ profile.name }}</h1> This is my first time rendering this from scratch, I know I'm missing something dumb I just can't sort it. Thank you! edit This current setup receives a 500 error. Without the get(pk) statement it loads, but doesn't show the variables, just the rest of my HTML. -

Configure Nginx with Vue.js, Django Rest Framework as backend and /api/ on same server?
I am in a process of deploying my newly developed e-commerce to a Ubuntu server that I have. I have already set up Nginx for Frontend and for Backend. The whole application is working fine. The only problem is DRF API that doesn't get anything from the backend (it doesn't send emails, users can't register). All of that gets error 500. It seems to me that I still need to add /api/ to my Nginx configuration, but when I do that the whole app goes down. Could someone explain the best way to set this up in "sites-available"? Thank you!

Django Customize PasswordResetView: __init__() missing 1 required positional argument: 'user'
I try to customize Django PasswordResetView in order to validate the length of the password but I get this error: TypeError at /accounts/password_reset/ __init__() missing 1 required positional argument: 'user' views.py from django.contrib.auth import views as auth_views class PasswordResetView(auth_views.PasswordResetView): form_class = PasswordResetForm template_name = "accounts/users/password_reset.html" email_template_name = "accounts/users/password_reset_email.html" subject_template_name = "accounts/users/password_reset_subject.txt" from_email = settings.EMAIL_HOST_USER success_url = reverse_lazy("accounts_password_reset_done") forms.py class PasswordResetForm(SetPasswordForm): def clean_new_password1(self): password = self.cleaned_data.get("new_password1") if len(password) < 12: raise forms.ValidationError("Password must be at least 12 characters.") return password It is obvious that SetPasswordForm class needs to be taken user upon initialization: class SetPasswordForm(forms.Form): . . . def __init__(self, user, *args, **kwargs): self.user = user super().__init__(*args, **kwargs) I do not find a clear solution to how to pass user data to PasswordResetView and PasswordResetForm because user data is used upon PasswordResetForm instance creation. -

Can I use a keyword argument from another app to connect the URLs of two different aps together?
I'm currently developing an application using the Django REST Framework and Vue in which people can monitor a device's signal outputs. For some context, I created a custom user model with a unique UUID4 user ID that would be assigned to each user. This model is in a Django app that I called accounts. Similarly, I have the user's data recording sessions and associated data in separate models in an app that I call studio. My problem is this: I realized I would like to associate the data collected to the user's account and whatever session they wish to tie this data to. However, since these models are in different Django apps, I am getting the error get() got an unexpected keyword argument 'user_id' when I try to tie the URLs of the account and studio apps together. Relevant code snippets are below: models.py (in studio) from django.db import models class Session(models.Model): user_id = models.ForeignKey( 'accounts.CustomUser', on_delete=models.CASCADE) session_id = models.CharField(max_length=100, unique=True, blank=False) def get_associated_user_id(self): return (f'{self.user_id}') def __str__(self): return (f"Session ID: {self.session_id}") class LaserData(models.Model): user_id = models.ForeignKey( 'accounts.CustomUser', on_delete=models.CASCADE) session_id = models.ForeignKey('Session', on_delete=models.CASCADE) timestamp = models.DateTimeField(auto_now_add=True) laser_current = models.DecimalField(max_digits=8, decimal_places=3) laser_temperature = models.DecimalField(max_digits=8, decimal_places=3) laser_temperature_set = models.DecimalField(max_digits=8, decimal_places=3) tec_voltage_positive = … -
