How to handle user reports for content e.g. inappropriate posts and profiles?
My Django app will allow users to report inappropriate posts and profiles etc. I want to be able to store these reports so that they can be reviewed by an admin. The ways I'm thinking of doing it is to either create a table in the database and store it there or just store it in a CSV / text file. Is there a better way to handle this feature? -
Passing Javascript variables to python main.views in Django
I am trying to send a variable from javascript to a python function in main.views, and I am using the Django web framework. I am very new to web development and I would really appreciate it if you showed some code for how to do it. Here is my variable (in home.html): <script> var my_var = 10; </script> and I need to send this to a function in main.views. My main.views looks like this so far: from django.shortcuts import render def homepage(request): return render(request, "main/home.html") def get_var(request): my_var = # I WOULD LIKE TO RECEIVE THE VARAIBLE HERE print(my_var) and so far here is my main.urls: from django.urls import path from django.conf.urls import url from . import views urlpatterns = [ path("", views.homepage, name="homepage"), ] Thanks for the help! -

I am giving up slowly, please help! I have three-step form to create two objects Pet and LostPet.

make ugettext/ugettext_lazy to mark messages for translation in a list
I have a lot (a Lot) of lists that should be marked for translation in django. Instead of wrapping each element of a list into _(...) I thought I could pass an entire list to a function that would loop over each element marking it for translation. Apparently something like this does not work due to lazy evaluation of the function (the items are not added to django.po after django-admin makemessages command). from django.utils.translation import ugettext as _ a = ['x','y'] b = [_(i) for i in a] Is there any way to bypass this limitation? -

Convert Django Views to rest services
I have an application created long back, now client want to expose its some of views as APIs without breaking existing functionality, so that they can directly consume APIs using REST Tools to see the reports. Is there any easier way, I can convert my function to a REST View. P.S - I kept code shorter here to keep question simple, but in fact, its much complex in the actual app. eg. URL : - `path('/users', views.show_user_details, name='users'),` VIEW def show_user_details(request, user_id): users = User.objects.all() return render(request, "Users.html", {"users":users}) In REST Views, I want it to convert its input and output so that it can be accessible with same urls(or with little modifications), without much updating the existing views. `path('rest/users', views.show_user_details, name='users'),` #-- I am ok to add new url like this, but without much change in existing view . def show_user_details(request, user_id): users = User.objects.all() return JsonResponse({"users":users}) -

Django update selectize on new foreign key in admin template
Some back story: I have overridden Django admin templates completely. Everything works fine. In the change_form.html, I have initialized the selectize.js through the following script: <script> $('select').selectize({ create: false, sortField: 'text', }); </script> Now, everything looks and works fine but I'm having a little problem when I click the add button on in the related_field_wrapper for that foreign key. I press it, the pop-up opens and the object gets created for that model but it doesn't update selectize for that field. Like it doesn't show it in the selectize options list but if I don't change anything else on that select field, it actually doesn't show that the object is selected but upon saving, it saves the newly created object in that field. This means that the field is being set in the select field but selectize just doesn't update. I understand that this might be a very specific request and that it's less Django related and more JS/Selectize related but I'd really appreciate some help. A starting point, I think would be to know what functions are performed upon creating a new object or updating Selectize when a new object is created. I'm lost guys. Thank you for reading … -

debugging selenium LiveServerTestCase in vscode
I run functional tests in django using the LiveServerTestCase class. When I want to write a new test, I put a breakpoint in vscode, then inspect the page to work out the selenium command which will activate the next step. I run it in the DEBUG CONSOLE, wait for the next page to load and repeat the process: inspect, write command in DEBUG CONSOLE, wait for next page to load. That's worked great for me in the past, but now it no longer works. I'm not sure if I inadvertently changed a setting, or if django or vscode updates have broken the process, but when I run the next selenium command in the debug window, the browser window just sits there with a status message "waiting for localhost..." ; sometimes 5 or 10 minutes later it will advance. Anyone else had experience with writing Selenium scripts this way who has an idea why the server thread in vscode seems no longer to respond when it is stopped at a breakpoint? My vscode's launch.json entry: { "name": "test particular functional test", "type": "python", "request": "launch", "program": "${workspaceFolder}/manage.py", "console": "integratedTerminal", "args": [ "test", "functional_tests.tests.test_selenium.test_coach_with_no_students", ], "django": true }, I'm not supposed to … -
