How to display blog post description structured correctly for a Django blog?
I am creating a blog where it displays the post description in a blog post. But the post data is displaying odd or continues text. I want post description to display same in a proper format that is given as an input. In Urls.py path('blog_single/<str:title>/', views.blog_single, name = 'blog_single'), In Views.py def blog_single(request, title): posts = Post.objects.get(title = title) recent_posts = Post.objects.all().order_by('-posted_at')[:5] Categories = Category.objects.all() context = {'posts':posts, 'recent_posts':recent_posts , 'Categories': Categories} return render(request, 'blog-single.html', context) In blog-single.html <div class="entry-img"> <img src="{{posts.thumbnail.url}}" alt="" class="img-fluid"> </div> <h2 class="entry-title"> <a href="#">{{posts.title}}</a> </h2> <div class="entry-meta"> <ul> <li class="d-flex align-items-center"><i class="bi bi-person"></i> <a href="blog-single.html">{{posts.user}}</a></li> <li class="d-flex align-items-center"><i class="bi bi-clock"></i> <a href="blog-single.html"><time datetime="2020-01-01">{{posts.posted_at}}</time></a></li> <!-- <li class="d-flex align-items-center"><i class="bi bi-chat-dots"></i> <a href="blog-single.html">12 Comments</a></li> --> <li class="d-flex align-items-center"><i class="bi bi-list"></i> <a href="blog-single.html">{{posts.category}}</a></li> </ul> </div> <div class="entry-content"> <p class="post__description"> {{posts.description|safe}} </p> </div> <div class="entry-footer"> <i class="bi bi-folder"></i> <ul class="cats"> <li><a href="#">Business</a></li> </ul> <i class="bi bi-tags"></i> <ul class="tags"> <li><a href="#">Creative</a></li> <li><a href="#">Tips</a></li> <li><a href="#">Marketing</a></li> </ul> </div> </article><!-- End blog entry --> In Models.py file class Post(models.Model): category = models.ForeignKey(Category, on_delete=models.CASCADE, related_name = 'categories') user = models.ForeignKey(User, on_delete=models.CASCADE, related_name='users') title = models.CharField(max_length =255) thumbnail = models.ImageField(upload_to = 'post/thumbnail') description = models.TextField() tags = models.CharField(max_length=255) posted_at = models.DateField(default = datetime.now) is_published … -
How to put a warped image on top of another using Python PIL?
Here's an example: (you can test it as a site user in the URL below) https://placeit.net/c/mockups/stages/t-shirt-mockup-of-a-cool-man-posing-in-a-dark-alley-2357-el1?iref=apparel-mockups-best-sellers-output User will upload an image and it will be applied as tshirt design on the mockup. I am not expecting to be able to develop a mega website such as Placeit but I would like to learn if similar to this very webpage in the url above. My initial idea is to use PIL lib of Python and then Django. If not, could you give me Python libraries that are more suitable? or other workaround? I understood that it includes atleast 2 images. First image is the tshirt with guy that I can do in photoshop with transparent layer on the shirt part along with shadows to make it look realistic (the folds in the shirt). Second image is the user's uploaded image. And yeah, the combining of two image is what I would like to know, esp the warped part. Tried PIL in combining the 2 images but it is only one on top of another, the warped part is the hard part. I guess its not only PIL but no idea which API or library to use. -

NoReverseMatch at /reset/done/ 'user' is not a registered namespace
I am trying to finalize the password reset process and after the user changes the password and click on save changes I keep getting this error: NoReverseMatch at /reset/done/ 'user' is not a registered namespace Here is the main urls.py urlpatterns = [ path('', include('django.contrib.auth.urls')), path('users/', include('users.urls'), ), path('admin/', admin.site.urls),] Here is the users urls.py app_name = 'users' urlpatterns = [ path('password-reset/', auth_views.PasswordResetView.as_view(template_name='users/password_reset.html', success_url=reverse_lazy('users:password_reset_done')), name='password_reset'), path('password-reset/done/', auth_views.PasswordResetDoneView.as_view(template_name='users/password_reset_done.html'),name='password_reset_done'), path('password-reset-confirm/<uidb64>/<token>/',auth_views.PasswordResetConfirmView.as_view(template_name='users/password_reset_confirm.html',success_url=reverse_lazy('users:password_reset_done'),post_reset_login=True),name='password_reset_confirm',), path('password-reset-complete/', auth_views.PasswordResetCompleteView.as_view(template_name='users/password_reset_complete.html'),name='password_reset_complete'), ] My question I guess the reason for these new errors showing up is due to Django or python version however when the user clicks on forget password and inserts the email they receives an email and when the click on the email link to reset the password it takes them to a Django Admin page (for some reason I am trying to figure out anyways) and when they insert the new password and click on the save changes it shows this error.

How to use safe filter on custom Django tag?
I'm trying to implement a custom Django tag that will formulate an import statement in Javascript to load my vue3 app as well as its components template html files using a get request in axios. The custom tag in my templatetags directory looks like this: templatetags/vuecomponents.py from django import template from django.templatetags.static import static register = template.Library() @register.simple_tag def v_load_app_component(app_name, script_name, components): components = components.strip("[]").split(", ") app_script = static(f"js/{script_name}.js") comps = [static(f"components/{name}.html") for name in components] return f"import {{{ app_name }}} from \"{app_script}?{components[0]}={comps[0]}\"" Right now it only loads the first component as I just want a prototype. The only issue is when I drop this into a template like so: createpost.html <script type="module"> {% v_load_app_component "creator" "internalpostform" "[internalpostform]" %} // OUTPUTS: // import { creator } from &quot;static/js/internalpostform.js?internalpostform=internalpostform.html&quot; creator.mount("#app") </script> It outputs the relevant import statement as: import { creator } from &quot;static/js/internalpostform.js?internalpostform=internalpostform.html&quot; With the double quotes escaped. Even when I tried to apply the safe filter ({% v_load_app_component "creator" "internalpostform" "[internalpostform]"|safe %}) it still escaped the output of my custom tag function. How can I make it to where the output of my custom tag doesn't automatically have symbols converted to html entities? -

CSRF fails on Route 53 redirect
I have two EC2 instances, which one has main Django-based backend app and another one has separate React-based frontend app using some of backend data. The backend app has its own views and endpoints and some frontend separate from the app in another EC2 instance. I got a new domain in AWS Route 53 which redirects to the frontend app and its location is configured on nginx. The missing thing are session cookies and csrftoken from the backend to make use of database. What may be useful is the frontend app is already reachable from the redirect set up in Django view but from the base server. In the example code below I don't paste the whole config but just the concept what I want to reach. Is there a way to redirect domain traffic to frontend app but through the backend to retrieve the cookies required to reach the backend data? Or should I think about other solution to make use of the domain? server { ... some server data ... $backend = "aws-backend-dns"; $frontend = "aws-frontend-dns"; location @backend { proxy_pass http://$backend; return @frontend; # but with some magic to keep the cookies! } location @frontend { proxy_pass http://$frontend; … -

Best practices for storing encrypted data that needs to be decrypted
I have a use case where I need to store userIDs and passwords to access other systems in my DRF App with a PostgreSQL DB. I must be able to retrieve this information, but I don't want to store it in plain text in the data base. The credentials will be used to login to other systems to collect data. Hashing is not an option as I need to be able to decrypt the encrypted passwords as they will be used to log into other systems. I was thinking using a vault (hashicorp), but then I need to store the keys to access the vault. That seems just shifting the problem, but not a solution. I am looking for a encryption/decryption that has not more than 2 secrets (key and vector) that could be the same for all credentials and provides a single string per password that can be stored in the DB. No fancy PostgreSQL features that are not supported by Django/DRF. I am not looking for long explanations about that you should not store a userID/Password information in a DB! -

Django Authentication to use both email and username in exiting app
I am struggling with adding custom AUTHENTICATION_BACKENDS for my exiting app. I have all done with my app but now want to login with username or EmailID. I am successfully able to login with username and password. now just want to add EmailID as well.

JAVASCRIPT: After sending Item to Database (POST) the window.location.reload() does not work. How to refresh the Data in HTML-Template?
I recode a Tutorial on Youtube. Django, Python, HTML an Javascript. Everthing works fine exept the window.location.reload() function. I try some workarounds with windows.reload(true), window.href = window.href location = self.location and some more. I have a hunch that the reload is executed before or during the code before the reload. But I do not know. The goal is to send the data from the input to the database and only then refresh the page. This ist the Code from the tutorial: index.html (shortened) <body> <header> <h1>Shoppinglist</h1> <div id="input-field"> <label for="item-input">Was möchtest du einkaufen?</label> <input type="text" name="item" id="item-input"> </div> <button id="btn" onclick="addItem()">+</button> </header> <div id="item-table"> {% for row in all_items %} <div class="list-item"> <input type="checkbox"> {{row.name}} </div> {% endfor %} </div> <script> function addItem(){ let itemName = document.getElementById("item-input").value; let formData = new FormData(); let token = '{{csrf_token}}'; formData.append('itemName', itemName); formData.append('csrfmiddlewaretoken', token); fetch('/mylist/', { method: 'POST', body: formData }); window.location.reload(); }; </script> </body> </html> views.py from django.shortcuts import render from .models import ShoppingItem # Create your views here. def mylist(request): if request.method == 'POST': print('Received date: ', request.POST['itemName']) ShoppingItem.objects.create(name = request.POST['itemName']) all_items = ShoppingItem.objects.filter(done = 0) return render(request, 'index.html', {'all_items':all_items}) models.py from django.db import models from datetime import date #Create your models … -

Django Rest Framework get filtered queryset in custom get function
So I have an APIView like this: from rest_framework.views import APIView class MyAPIView(APIView): queryset = MyObject.objects.all() filter_backends = [MyCustomFilterBackend, DjangoFilterBackend] filterset_fields = ["field1", "field2"] def get(self, request): s = StatManager(self.queryset) return Response(s.dashboard()) where I filter bunch of stuff using MyCustomFilterBackend and DjangoFilterBackend. My goal is to give the filtered queryset to StatManager so it generates stats for the dashboard. Currently, s = StatManager(self.queryset) does not take filters into account. How can I provide the filtered queryset in my get function? I read the DRF documentation. I was expecting for APIView to have some function like get_filtered_queryset(). I read Filters of Django REST Framework inside GET function? and DJango filter_queryset but they have no adequate answers.
