Django: Setting a cookie asynchronously

Create equivalent paths in Django urls.py
I am attempting to create 2 url prefixes that would be equivalent in my app (this is due to some aesthetic user requirements), and am unsure the best way to go about this. The most straightforward option would be to create another set of urlpatterns with the alternate prefix. However, this would be repetitive and make maintenance more difficult. Is there a simpler way to make foo/<str:key>/ equivalent to bar/<str:key> and staff/<str:key>/ equivalent to foo/<str:key>/staff/? Current URLS urlpatterns = [ path('foo/<str:key>/welcome/', views.welcome), path('foo/<str:key>/dashboard/', views.dashboard), path('foo/<str:key>/staff/dashboard/', views.staff_dashboard), ] Desired Patterns urlpatterns = [ # Original paths path('foo/<str:key>/welcome/', views.welcome), path('foo/<str:key>/dashboard/', views.dashboard), path('foo/<str:key>/staff/dashboard/', views.staff_dashboard), # Alternate paths to the same pages path('bar/<str:key>/welcome/', views.welcome), path('bar/<str:key>/dashboard/', views.dashboard), path('staff/<str:key>/dashboard/', views.staff_dashboard), ] -

Django ASGI/Daphne: postgres connection timeout
In my project I am using a PG database. Now that I've deployed the app to the production server, I' ve switched from the test db (PG 10) to the production db (PG 9). When connecting the Django backend to the test db, everything works perfectly fine, but when I connect it to the production db, it works only for a couple minutes and then, after some time of inactivity for example, the whole site stops working properly. This is the data from daphne: log on imgur What pg settings could cause this? I don't really think that it's an issue with the app's config, because with the other db everything is working correctly. This prod_db is placed on an external server btw. -

Uncaught Error: Module build failed (from ./node_modules/babel-loader/lib/index.js): SyntaxError. Something went wrong with react and babel
I have some problems with React using Django. Everything was fine, until i wrote some text using cyrillic letters right into my react component code. Then i get this error in chrome console: Uncaught Error: Module build failed (from ./node_modules/babel-loader/lib/index.js): SyntaxError: C:\Users\Lenovo B590\Documents\DEV\React-DDJ.TWT\music_controller\frontend\src\components\createroompage.js: Unexpected token, expected ";" (43:20) [0m [90m 41 | [39m }[0m [0m [90m 42 | [39m[0m [0m[31m[1m>[22m[39m[90m 43 | [39m [33mОСТАНОВИЛСЯ[39m [33mНА[39m [33mТОМ[39m [33mЧТО[39m [33mПОЛУЧАЮ[39m [33mBAD[39m [33mREQUEST[39m [33mНА[39m [33mМОИ[39m [33mКЛЮЧ[39m [33m-[39m [33mЗНАЧНИЕ[39m[0m [0m [90m | [39m [31m[1m^[22m[39m[0m [0m [90m 44 | [39m[0m [0m [90m 45 | [39m fetch([32m'api/crapiview'[39m[33m,[39m requestOptions)[33m;[39m[0m [0m [90m 46 | [39m }[0m at Object._raise (C:\Users\Lenovo B590\Documents\DEV\React-DDJ.TWT\music_controller\frontend\node_modules\@babel\parser\lib\index.js:748:17) at Object.raiseWithData (C:\Users\Lenovo B590\Documents\DEV\React-DDJ.TWT\music_controller\frontend\node_modules\@babel\parser\lib\index.js:741:17) at Object.raise (C:\Users\Lenovo B590\Documents\DEV\React-DDJ.TWT\music_controller\frontend\node_modules\@babel\parser\lib\index.js:735:17) at Object.unexpected (C:\Users\Lenovo B590\Documents\DEV\React-DDJ.TWT\music_controller\frontend\node_modules\@babel\parser\lib\index.js:9097:16) at Object.semicolon (C:\Users\Lenovo B590\Documents\DEV\React-DDJ.TWT\music_controller\frontend\node_modules\@babel\parser\lib\index.js:9079:40) at Object.parseExpressionStatement (C:\Users\Lenovo B590\Documents\DEV\React-DDJ.TWT\music_controller\frontend\node_modules\@babel\parser\lib\index.js:12190:10) at Object.parseStatementContent (C:\Users\Lenovo B590\Documents\DEV\React-DDJ.TWT\music_controller\frontend\node_modules\@babel\parser\lib\index.js:11786:19) at Object.parseStatement (C:\Users\Lenovo B590\Documents\DEV\React-DDJ.TWT\music_controller\frontend\node_modules\@babel\parser\lib\index.js:11650:17) at Object.parseBlockOrModuleBlockBody (C:\Users\Lenovo B590\Documents\DEV\React-DDJ.TWT\music_controller\frontend\node_modules\@babel\parser\lib\index.js:12232:25) at Object.parseBlockBody (C:\Users\Lenovo B590\Documents\DEV\React-DDJ.TWT\music_controller\frontend\node_modules\@babel\parser\lib\index.js:12218:10) at eval (webpack://frontend/./src/components/createroompage.js?:1:7) at Object../src/components/createroompage.js (http://127.0.0.1:8000/static/frontend/main.js:2:4127) at __webpack_require__ (http://127.0.0.1:8000/static/frontend/main.js:2:251468) at eval (webpack://frontend/./src/components/homepage.js?:6:73) at Object../src/components/homepage.js (http://127.0.0.1:8000/static/frontend/main.js:2:7470) at __webpack_require__ (http://127.0.0.1:8000/static/frontend/main.js:2:251468) at eval (webpack://frontend/./src/components/app.js?:6:67) at Object../src/components/app.js (http://127.0.0.1:8000/static/frontend/main.js:2:2509) at __webpack_require__ (http://127.0.0.1:8000/static/frontend/main.js:2:251468) at eval (webpack://frontend/./src/index.js?:2:76) Obviously its due to cyrillic letters, so i deleted it.

How to ensure Django updates html to reflect changes?
Expected Result: I expect to see <p>B<p/> when I edit my home page from <p>A<p/> to <p>B<p/>, save changes in the editor, and refresh the browser. Actual Results: I'm seeing <p>A<p/> when I edit my home page from <p>A<p/> to <p>B<p/>, save changes in the editor, and refresh the browser. A week ago I was getting the "Expected results" but I noticed a few days ago I'm getting the results explained in "Actual Results". Now Only when I restart the server by running docker-compose up restart I'm getting the expected results. Why simple HTML changes not being updated when I refresh the browser? I'm using Django 3.1 and Python 3.7.
