How can I filter tags with django-taggit
I'm doing the following to filter the posts by tag. But the problem is when clicking the tag button, I do not see any results. urls.py : urlpatterns =[ ...... path('challengePage/', views.ChallengePage, name ='challengePage'), path('tag/<tag>', views.tag, name='tag_argument'), ] the views.py : def ChallengePage(request): challenges = Challenge_code.objects.prefetch_related('tags').all().order_by('-created_at') tags = Tag.objects.all() context = { 'challenges' : challenges, 'tags':tags, } return render(request,'challengePage.html',context) def tag(request,tag): challenges_tag = Challenge_code.objects.filter(tags__name__in=tag) return render(request, 'tag.html',{'tag':tag, 'challenges':challenges_tag}) the challengePage.html : <div style="text-align: center;"> {% for tag in tags %} <a href="{% url 'tag_argument' tag %}"><button style="text-align: center;" dir="ltr" class="buttonTag buttonTag2" > {{tag.name}}</button></a> {% endfor %} </div> the tag.html : <div class="code_body"> <div class="container_code"> {% for challenge in challenges_tag %} <div class="Box_code"> <p class="title_code"><bdi style=" color: #000;"> {{challenge.title}} <br> {% for tag in challenge.tags.all %} <small>{{tag}}, </small> {% endfor %} </bdi> </p> <a href="{% url 'challenge' challenge.id %}"><button class="button1" style="vertical-align:middle"><span>Join</span></button></a> <p class="name-user"> <bdi> By: {{challenge.auther.username}} </bdi> </p> </div> {% endfor %} -
Django Handling Multiple Image Uploads
I have a simple project that has two different models. One that handles a report and one that stores the images for each report connected by a ForeignKey: class Report(models.Model): report_location = models.ForeignKey(Locations, on_delete=models.CASCADE) timesheet = models.ImageField(upload_to='report_images', default='default.png') text = models.CharField(max_length=999) report_date = models.DateField(auto_now=True) created_by = models.ForeignKey(User, on_delete=models.CASCADE) def __str__(self): return f"{self.report_location, self.report_date, self.created_by}" class TimeSheetAndPics(models.Model): report = models.ForeignKey(Report, on_delete=models.CASCADE) report_images = models.ImageField(upload_to='report_images', default='default.png') date = models.DateField(auto_now=True) def __str__(self): return f"{self.report} on {self.date}" My Goal is to have a user fill out the report and then upload multiple pictures, however i cannot figure out how to handle multiple image uploads. I have two forms for each model: class ReportCreationForm(ModelForm): class Meta: model = Report fields = [ 'report_location', 'text', ] class TimeSheetAndPicForm(ModelForm): report_images = forms.FileField(widget=ClearableFileInput(attrs={'multiple': True})) time_sheets = forms.FileField(widget=ClearableFileInput(attrs={'multiple': True})) class Meta: model = TimeSheetAndPics fields = [ 'time_sheets', 'report_images', ] And this is how i try to handle my views: class NewReport(LoginRequiredMixin, View): def get(self, request): context = { 'create_form': ReportCreationForm(), 'image_form': TimeSheetAndPicForm(), } return render(request, 'rakan/report_form.html', context) def post(self, request): post = request.POST data = request.FILES or None create_form = ReportCreationForm(post) image_form = TimeSheetAndPicForm(post, data) if create_form.is_valid() and image_form.is_valid(): clean_form = create_form.save(commit=False) clean_form.created_by = request.user clean_form.save() clean_image_form = … -

How to connect my HTML file with CSS file inside of a Django Project
I have a simple html page that works and renders properly on my local browser, but when I reference the static css file the page loads without the styling and I get a 200 Success for the url but 404 for the style.css file I used <link rel="stylesheet" type="text/css" href="{% static 'css/style.css' %}"> inside of the HTML file. I have the static folder in the correct spot at the project level and then a css file inside that followed by the style.css file. The Html page: {% load static %} <!DOCTYPE html> <html> <head> <title>My Website</title> <link rel="stylesheet" type="text/css" href="{% static 'css/style.css' %}"> </head> <body> <h1>Home</h1> <header> <nav> <ul> <li><a href="{% url 'home' %}">Home</a></li> <li><a href="{% url 'about' %}">About</a></li> <li><a href="{% url 'info' %}">Info</a></li> </ul> </nav> </header> </body> </html> The CSS page: h1 { background-color: orange; } From the research I've done this should get the backgrounds of all the h1 tags orange but it is not working.

Build versioning for django
I would like to build versioning for my django models. I have already tried django-reversion but i think that is not good for my use case and i have problems with many-to-many through models and multi table inheritance. My use case: I have a multi tenant web app. Every tenant have their own pool of resources. The tenants can create documents and reference to the resources. Here is a simple diagram: Now on every update from the document or a resource that is referenced in the document i would create a version of the document. So the version should show all changes of the document and the referenced resources. But on revert to a version only the direct values of the document should reverted and not the resources. For example a document: Now i edit the document and delete the resource_1 with the id 1. Also i change the name from the resource_1 with the id 2. When i revert this document to the first version, it should look like this: But how can i achieve this? I think i can use MongoDB to store complete version of a document as serialized json data on every update. And can create … -

category id is stored as null for the user in django
I have started a django project where users have to select category while creating an account including other credentials. I have given .py file of Category, Post and CustomUser model below. The forms.py file is for the researcher-profile.html file. So when a user will login, the user will be redirected to this researcher-profile. I have set the cid in the CustomUser model as null so that I can create superuser. But for normal user, it is mandatory to select category which is why I gave specialization which is cid as required field in forms.py. But the problem is when a normal user registers an account from the registration page, then in the database it stores null in the cid field even though the user selected a category while registering.

How to upload multiple images with flags to Django
I am building a web page where a blog author can write content and upload images. Using an image field, I am allowing the author to upload multiple images and with some Javascript logic, I am displaying the images before upload. Under each image, I have a checkbox that indicates if that is the main image of the post (e.g. the first to show in the slideshow and used as thumbnail of the post itself). On this page I am showing two forms with a shared submit button and it works fine. My problems begin when I try to save the image and also indicate if it is the main one. My images model has multiple helpful methods, thumbnail property for Django admin and a save method that will set all images for a post to false, before editing/adding a new main_image. I had to include a commit argument logic because of my experiments. Please ignore it. The model includes 3 fields: the image, the main flag and a foreign key to the post as follows: class PostImages(models.Model): """ Post images for the blog app. """ image = models.ImageField( verbose_name=_("Изображение"), upload_to='blog/images/', blank=False, null=False, default='blog/images/default.jpg' ) post = models.ForeignKey( to=Post, on_delete=models.CASCADE, … -

OSError: No wkhtmltopdf executable found: "b'' in heroku
I am trying to download a pdf file using pdfkit on a website deployed on heroku. However, it is showing the error whenever I try to download. I have it running on the local server but it does not run on the heroku server. I tried using heroku-18 but it didn't work. -
Django - Ask users to confirm change of PDF file
I got a question regarding Fileupload. I got a form where users can upload PDFs and change the uploaded PDFs. When they change the PDF, I want to add a warning, asking them to confirm the PDF change. Any idea what's the best way of doing it? Right now, I'm trying to solve it with JS in my HTML, like so: <form enctype="multipart/form-data" method="post"> {% csrf_token %} <table> {{ form.as_table }} </table> <input type="submit" value="Submit"> <input class="deleter" type="submit" value="Delete"> {% include "some_html.html" %} </form> <script> // Add event listener to change button function confirmFileChange() { var fileInput = document.getElementById('id_file'); fileInput.addEventListener('change', function() { if (fileInput.value) { if (!confirm('Are you sure you want to change the uploaded PDF?')) { fileInput.value = ''; } } }); } if (document.body.innerHTML.indexOf('Change: ') !== -1) { confirmFileChange(); } </script> But this also displays the warning upon first upload, when the user isn't changing anything. -
