Django template: src attribute doesn't work
I've been doing some practice with Django and lately I ran into a problem that I can't solve. I'll give you some context. I have this models (I think you can just focus on the fact that the model has a gitUrl function): class AllTemplates(models.Model): categories = [ ('landing-page', 'landing-page') ] id = models.IntegerField(primary_key=True) name = models.CharField(max_length=100) image = models.ImageField(null=True, blank=True) category = models.CharField( max_length=200, choices=categories, default='landing-page') url = models.CharField(max_length=500, null=True) def __str__(self): return self.name @property def templateNumber(self): try: number = self.id except: number = '' return number @property def templateTitle(self): try: title = self.name except: title = '' return title @property def imageURL(self): try: url = self.image.url except: url = '' return url @property def gitUrl(self): try: gitPath = self.url except: gitPath = '' return gitPath The purpose of this model is to keep all the templates I develop in the database. Each template has various fields including 'url', in which I store the github url where the template in question is located. What I can't do is: dynamically make each template have an html file, in which there is an iframe tag whose src attribute points to the github url. Here's what I tried to do. My urls.py … -

Django: How to store data in Form #1 while filling up Forms #2 and #3 and import data from Forms #2 and #3 into Form #1?
I have a Vinyl model form (Form #1) that creates vinyl with the following fields: artist (ManyToManyField), title, record label (ForeignKey), cat.number, release date, cover art, price, genre, style, tracklist, quantity, and condition. Under artist and record label there are buttons that allow the user to create new entities. When pressing the "Add new artist" button, a new form (Form #2) is shown and I would like to have the already added data in Form 1 to be preserved and get the data from Form #2 populated into Form 1. Example: The artist I'm looking for is not on the list of artists in Form 1. I click "Add new artist" and Form #2 appears. I fill in the data and when clicking submit, I get redirected to Form #1. I want this new artist to be autoselected. Then I write the title. Then I see that the record label is not on the list of record labels so I click "Add new label". Form #3 is shown and I fill in the data. When clicking the submit button I'm redirected to Form #1. I would like to have all the previously added data and also the newly generated record … -

Can I use a prevent default at a form that uses GET as a method in the Django HTML template?
I’m looking to create a section about searching for some movies in my database, however, this section is at the bottom of my page. However, when I search and find the movie that I was looking for, the page refreshed. Also, I do not know if “GET” is the ideal method for secure sections, but I read that POST is necessary just for database changes. In this case, I just want to bring the movie corresponding to what was searched at a search bar. This is my view and I am getting the search like this, in the context, to make it easier to render. It is working ok. class MoviesPage(TemplateView): template_name = "tailwind/movies-page.html" def get_context_data(self, **kwargs): context = super(MoviesPage, self).get_context_data(**kwargs) # Top Movies' section movies = Movies.objects.filter( name__in=[ 'Oldboy', 'Parasite', 'Lady Vengeance', ] ) context['movies'] = movies # Movie search's section query = self.request.GET.get('q', default='oldboy') results = Movies/.objects.filter(Q(name__icontains=query)) context['results'] = results This is my form in my HTML template: <form action="" method="GET" id="search-package-form" > <input type="search" name="q" placeholder="oldboy" /> <div> <button type="submit" > <span>Search</span> </button> </div> </form> {% if results %} <div> {% for movie in results %} <ul> <li>{{ movie.name }}</li> </ul> {% endfor %} </div> {% else … -

Django multiple sites using nginx and gunicorn

FileNotFoundError at / [Errno 2] No such file or directory while saving an image
I want to create a qr-code generator for hashed values. However, it works pretty strange, because sometimes everything works good, but sometimes it gives me an error: FileNotFoundError at / [Errno 2] No such file or directory. For example, it can save a few qr-codes and then throw that error. Here is the code: def qr_creator(request): for i in range(50): hash_uuid = uuid.uuid4 hash = Hasher.encode(self=Hasher(), password=hash_uuid, salt=Hasher.salt(self=Hasher())) data = f"{hash}" img = make(data) img_name = f"{hash}.png" img.save(str(settings.MEDIA_ROOT) + '/qr_codes/' + img_name) return HttpResponse("Done!") As I understand, the problem lies in img_name as if I change it for example, like this: img_name = f"{hash}.png", everything works as it should be. But I need my qr-codes to be named strictly as hash values. So my question is how can I fix this so I can save my qr-codes with its values? Thanks in advance
