"Relation does not exist" after delete migration files
Can you please explain, why I get some issue after deleting migration files from database and in local? If the relation does not exist, how can I create this relation? I have active ForeignKey, but uncommented and commented the field and trying makemigrations, migrate, migrate --fake didn't work for me anyway. -

Showing data on frontend from sql databases using django
For fetching data from databases, I usually see people create a class in models.py and they migrate it, and then they fetch data from databases and show it on the front-end. my question is, i already have a database which has student_info table and has lots of data. I don't want to define student_info class in models.py and do migration. Instead, since i already have student_info data in sql database. so I want to fetch it directly. can i do so? one method i know of doing the same, is directly connecting sql server in views.py as; mydb=mysql.connector.connect(host="localhost",user="root",password="******",database=database_name) and fetching the data and passing it as variable in index.html. But the problem is, it fetches data only once, and if i refresh the page where local server is running, all the content will disappear, and server will report Broken pipe from ('127.0.0.1', 59579) and to see the data, again i need to restart the sever. Kindly looking for a better approach to show data on front-end from the existing databases -

Django/Vue -> Heroku: Static files not loading at production server
Static files load when DEBUG=True (locally and at the dev server), but not when DEBUG=False (production). STATICFILES_DIRS is set to my dist dir created by Vue, and dist is not in the .gitignore. Heroku runs collectstatic on every deploy by default (I have not changed this). The actual error is a 404 when trying to load any static file. The whitenoise package is being used. I've updated the middleware settings, and wsgi.py according to the docs, and have the settings variable which enables compression via whitenoise set (also according to the whitenoise docs). whitenoise usually works fine with other apps. I'm not sure what's wrong with this. The difference is that I'm using Vue for the first time. I'd never used a js framework before. Can anyone help? -

How to make AlpineJS "re-render" component after HTMX swap
I'm trying to integrate Django + AlpineJS + HTMX. All is going well, except when I try to swap some HTML that is already a part of a AlpineJS component. If I swap the html the component renders correctly only after the second swap. template <div id="cart-row" x-data="{selectedOrderItem: {{item_id|default:'null'}} }"> <div id="cart-holder"> <table id="cart"> <thead> <tr> <th style="width: 10%">CANT</th> <th>Product</th> <th style="width: 15%">TOTAL</th> </tr> </thead> <tbody> {% for item in items %} <tr id="product{{item.product.id}}" :class="{ selectedOrderItem: selectedOrderItem == {{item.id}} }" @click="selectedOrderItem = {{item.id}};" > <td>{{item.quantity}}</td> <td>{{item.product.name}}</td> <td>{{item.get_price}}</td> </tr> {% endfor %} </tbody> </table> </div> <div id="right-menu"> <div id="table-buttons" hx-swap-obb="true"> {% for item in items %} <div class="" x-cloak x-show="selectedOrderItem == {{item.id}}"> <button class="addButton" hx-trigger="click" hx-target="#cart-row" hx-swap="outerHTML" hx-post="{% url 'add_to_cart' idOrder=order.id idProduct=item.product.id %}?cartAction=1" > + {{item.id}} </button> </div> {% endfor %} </div> </div> For example, if I hit the add to cart button, the #cart-row div is swapped, but the :class="{ selectedOrderItem: selectedOrderItem == {{item.id}} }" binding only works the second time. It's like AlpineJS doesn't realize that the content has been swapped. Is there any way that I can make the whole component "re-render / re-initialize"? Or what is the right way to do that swap? -
Django file uploads not working; Getting 404 error when trying to retrieve them. Page not found (404) does not exist
I made a custom user model that users can get to upload their profile pics and documents. I made the view to update these details and insert them into the database. However, when I try to retrieve the file I get a 404. They were never uploaded in the first place, even though the file field has been populated with the name and path.

How to serve media files correctly in django subdomains (using django-hosts) in development?
I have this model Blog and using it in 'blog' subdomain created with 'django-hosts'. My subdomains in 'hosts.py': from django.conf import settings from django_hosts import patterns, host host_patterns = patterns('', host(r'blog', 'blog.urls', name='blog'), host(r'(|www)', settings.ROOT_URLCONF, name='www'), ) And Blog model - Note that 'title_image' field powered by 'sorl.thumbnail' and 'content' field is a 'django-ckeditor' uploadable field: class Blog(models.Model): author = models.ForeignKey(settings.AUTH_USER_MODEL, verbose_name=_('author'), on_delete=models.CASCADE, related_name='blog_author') title = models.CharField(verbose_name=_('title'), max_length=200) title_image = ImageField(verbose_name=_('title image'), blank=True) content = RichTextUploadingField(verbose_name=_('content')) I've' created a simple ListView for blog that show every blog title, content and title_image to viewer: class BlogListView(ListView): """Everyone can see all blogs""" template_name = 'blog/templates/blog/blog_list_view.html' model = Blog context_object_name = 'blogs' And my blog.urls: from django.urls import path from . import views app_name = 'blog' urlpatterns = [ path('', views.BlogListView.as_view(), name='blog_list_view'), ] When I'm using my blog subdomain (eg: blog.localhost:8000/) it doesn't show any image to me whether it's the title_image or any image in django-ckeditor powered 'content' field. But when I'm not using subdomain and instead use 'blog' app as other 'URLCONF' path (eg: localhost:8000/blog/) I can see every images without any problem. Anyone knows why using subdomains, media files does not shown and how to fix it? -
