Obtain absolute path on image ckeditor + django + react
Django There are 2 question about this topic, but both of them (this is one Absolute paths on images uploaded by django-ckeditor) are not updated. For example, in Django 4.X, url was removed. Despite this, I've tried these solutions, but no one worked for me. I've also tried to use: CKEDITOR_MEDIA_PREFIX on my settings.py But it didn't work either. So here is my question, how can I set up my Django-rest-framework app in such way that I get the absolute path when I render the html on my next.js site? This is what I get right now: <img alt=\"\" src=\"/media/uploads/2022/01/19/video.svg\"/> This is what I'd like to get: <img alt=\"\" src=\"http://website.com/media/uploads/2022/01/19/video.svg\" React Is there any way to achieve these from the frontend? For example, updating all img's src -
Why do I get model DoesNotExist but server is able to display it?
I don't understand the Traceback of the error, but Server is running fine (0 problems), and I get all the data I needed from the view.py. Seems it has to be with the get() method... DoesNotExist: matching query does not exist This are the models I used. from django.contrib.auth.models import AbstractUser from django.db import models class User(AbstractUser): id = models.AutoField(primary_key=True) name = models.CharField(max_length=64, blank=True) image = models.ImageField(upload_to="portraits", blank=True, default="default.jpg") def __str__(self): return f"{self.username}" class Category(models.Model): id = models.AutoField(primary_key=True) name = models.CharField(max_length=64) description = models.CharField(max_length=255, blank=True) def __str__(self): return f"{self.name}" class Item(models.Model): id = models.AutoField(primary_key=True) owner = models.ForeignKey(User, on_delete=models.CASCADE, related_name="inventory") name = models.CharField(max_length=64) description = models.CharField(max_length=255) image = models.ImageField(blank=True, default="Megamind.jpg") starting_bid = models.PositiveIntegerField(default=0) category = models.ForeignKey(Category, on_delete=models.CASCADE, default="1", related_name="stuff") active = models.BooleanField(default=True) favorited = models.ManyToManyField(User, blank=True, related_name="favorites") def __str__(self): return f"{self.name} of {self.owner}" and the related view.py file def index(request): auctions = Item.objects.filter(active=True) context = {'auctions':auctions, 'title':'Active Listings'} return render(request, "auctions/index.html", context) def category_view(request, category): category = category.capitalize() category_obj = Category.objects.get(name=category) category_id = category_obj.id items = Item.objects.filter(category=category_id, active=True) context = {'auctions':items, 'title':category} return render(request, "auctions/index.html", context) If it helps: I'm passing from urls.py to view as str path("<str:category>", views.category_view, name="category") -
How to render Django context data (JSON) within external JavaScript file?
The question I have is: How do I get template-ed JSON data to be usable by .js file to see and use JSON data from my Django context? The problem I am trying to solve is: I am working on adding a CSP (Content Security Policy) to my Django website. The catch is that I have some inline JavaScript when templating JSON variables. This wouldn't be a problem, but the templating is inside the JavaScript section of the .html file. Thus, in order to abide by a strict CSP, I need to move the entire JavaScript portion out of the .html file and into a .js file. The code I need to move looks like this: <script> let data = [ { "key" : "Last 10 Days", "values" : {{ last_ten_days }}, }, { "key" : "Daily Score", "bar": true, "values" : {{ daily_scores }}, } ].map(function(series) { series.values = series.values.map(function(d) { return {x: d[0], y: d[1] } }); return series; }); </script> I am passing the values via a Django TemplateView to the context so I can render the data to plot, using NVD3.js, on my webpage. It looks something like this: class TheScores(LoginRequiredMixin, TemplateView): template_name = 'the_scores.html' def … -

I would like to know how to count all the true/false booleans inside a for-loop in my django template, but im not sure how to achieve this inside the loop.

If else statement in django template based on request.session data

It works for blocking it, but once the key is added to the session, that isn't reflected on the webpage/template and the key remains blocked.

Uploading images in django
I have being using django for sometime but recently noticed this. Before now I thought images in django, by default, gets uploaded in the path specified in STATIC_URL but I just saw that the bahaviour is diffrent in my app. I have this set up in settings.py: class BlogPost(models.Model): author = models.ForeignKey(settings.AUTH_USER_MODEL, null=True, on_delete=models.CASCADE) category = models.CharField(max_length=50, choices=Categories.choices, default=Categories.medications) title = models.CharField(max_length=50) slug = models.SlugField() image = ResizedImageField(upload_to='images/blog/', null=True, blank=True) introduction = models.CharField(max_length=255) body = models.TextField() settings.py STATIC_URL = '/static/' STATIC_ROOT = os.path.join(BASE_DIR, 'staticfiles') STATICFILES_DIRS = [ os.path.join(BASE_DIR, 'static',), os.path.join(BASE_DIR, 'frontend/build/static'), ] MEDIA_URL = '/media/' MEDIA_ROOT = os.path.join(BASE_DIR, 'media/') The static, staticfiles, and media are within the root directory.
