Django include template tag include multiple context object
I`m building a blog template page, which will include the Post list context object and the Category list context object. I`m using class-based view in the views.py: class CatListView(ListView): model = Category context_object_name = 'categories' template_name = 'blog/category.html' class PostListView(ListView): model = Post context_object_name = 'post_list' template_name = 'blog/blog.html' urls.py: urlpatterns = [ path('', views.PostListView.as_view(), name='blog'), ... ] using the include tag to include the category template in blog.html: {% extends 'base.html'%} {% block content %} <main class="main-content"> <div class="container mt-8"> <div class="row"> <div class="col-lg-8"> <h2>Post list</h2> {% for post in post_list %} {{ post.title }} {% endfor %} </div> <div class="col-lg-4"> {% include "blog/category.html"%} </div> </div> </div> </main> {% endblock %} category.html: <ul class="mt-8"> {% for cat in categories %} <li>{{ cat.title }}</li> {% endfor %} </ul> I just cant pass the category context in the post.html template. maybe Im can do it with the function-based view, but is it possible to pass multiple contexts into one template using only a class-based view? -
Django ReactJS - Exposing multiple graphql endpoints
I am building a web app using Django backend and ReactJS frontend. This web app will be a culmination of several smaller applications like Todo app, Investments Tracker, Budget Analysis etc. Frontend: This I how I have structured the frontend (ReactJS project): src - apps - Home - index.jsx - Todo - index.jsx - Expenses - index.jsx - Investments - index.jsx - index.js - App.jsx App.jsx function App() { return ( <Routes> {/* COMMON ROUTES */} <Route path="/todos" element={<Register />} /> <Route path="/activate/pending" element={<PendingActivation />} /> <Route path="/activate" element={<Activate />} /> <Route path="/login" element={<Login />} /> {/* APP ROUTES */} <Route path="/todos" element={<Todo />} /> <Route path="/expenses" element={<Expenses />} /> <Route path="/investments" element={<Investments />} /> </Routes> ); } function AppWrapper() { return ( <Provider store={store}> <BrowserRouter> <Alerts /> <App /> </BrowserRouter> </Provider> ); } ReactDOM.render(<AppWrapper />, document.getElementById('root')); Based on the endpoints, I will route the User to one of the sub-apps.

Django - Accessing the same view with complex lengthy algorithm by several users in the same time
I am trying to implement an anonymous chat web application in Django. Right now I am on the stage where I need to connect users with each other based on their preferences, location etc. So I have a view find_room(request), where I am executing lengthy algorithm which runs for a few seconds, trying to find the closest user who is also searching for other users using the same view. So my problem is that when one user is calling the find_room view and then the other user calling the same view, then the second user should wait until first users's call is ended. So basically I need this view to be executed as a separate thread, so that several users can call this view and use this searching algorithm in the same time. Is there any functionality inside django that can help me? Or are there any other technologies I should use? (I heard about celery, but not sure if this is right thing for my purposes). Sorry if the question is confusing, and thanks for the answers! -
My registered accounts in herokuapp is not shown in django admin
I have created a django app and deployed it in Heroku. The web app works fine and the user registration and login works too.

Is it possible to MOVE items in a database in django without deleting them?
I have a simple model in Django for a Library Manager. Inside there are 3 models. One to record all the books, another to issue the books and the last one to return the issued books. I already have the relationships done, but the problem arose when I wanted to issue a book. If a book is issued it should no longer be in the book records but rather be in the issued records. And when it is being returned it should go through the return class and get added to the book record. My question is "is it possible to move books in my case from on class to another?" -

Django Forms: Default Value in get request
I am building a personal finance site that displays monthly transaction information on the homepage. I want the user to be able to switch months via a dropdown. Thankfully I already have the code built to filter on transaction date, what I am having trouble with is displaying a default value in the dropdown. The dropdown is populated by a dictionary (month_year_select) as you can see in forms.py below. I am not getting any error messages, the application just isn't performing the way I need. My question is how do I get the current month (Jan, 2022) to display by default in the dropdown when the user navigates to the homepage? The page already displays the current month's data, but the dropdown just lists the most recent month. I have looked through a ton of posts on this and the one that seems to have the closest explanation to what I need is here django forms: default values for bound forms I realize the views.py code is messy, I apologize in advance.

SQLite seems to ignore db_table parameter when running tests on MacOS but works fine on Ubuntu
So, the problem is when I'm running Django tests on MacOS I'm getting the following errors: Traceback (most recent call last): ... django.db.utils.OperationalError: no such table: main.estimates_estimate The above exception was the direct cause of the following exception: Traceback (most recent call last): ... raise CommandError( django.core.management.base.CommandError: Database file:memorydb_default?mode=memory&cache=shared couldn't be flushed. Possible reasons: * The database isn't running or isn't configured correctly. * At least one of the expected database tables doesn't exist. * The SQL was invalid. Hint: Look at the output of 'django-admin sqlflush'. That's the SQL this command wasn't able to run However, it passes if I change database to MySQL. Also, it passes on Ubuntu 20.04 with SQLite as DB backend. It just seems like db_table option of a model is ignored for some reason. class Estimate(models.Model): class Meta: db_table = "estimates" On Ubuntu db.sqlite3 has estimates table after the tests run is complete but on MacOS there is estimates_estimate. What I've tried I was looking for any possible difference of sqlite on Mac/Linux but couldn't find anything related. Also, I have tried to remove __pycache__ dirs and different Django versions (2.2 and 3.2). I've created a dummy app with the same file structure and … -
What is `*args` in a Django BaseCommand handle function for?

React unable to read property of undefined

Problem recovering django with pipenv after crash
I recently had a catastrophic hard drive failure and I had not pushed all of my recent commits to a remote repository (I have learned my lesson). Fortunately I did have a copy of most of my latest work. I recreated my local environment (I thought correctly but maybe not) and attempted to start the project with the files. When I run "pipenv shell" the env appears to activate and running "git branch" does show the two branches. However when I ran "python manage.py migrate" I received the following error: (sitefolder) user@users-MBP ohive % python manage.py migrate File "manage.py", line 17 ) from exc ^ SyntaxError: invalid syntax When I run "python -V" it returns 2.7.18. The python version should be 3.9.6. When I do start pipenv shell in a folder without the old files, the correct version is returned. Any ideas about how I can get the pipenv to use the correct version of python? -
