In mpld3 how to make draggable line using mouse pointer?
I am trying to drag red vertical line in vertical direction towards right and left side using mouse pointer and on release I want to print x-axes value.

Setting up React.js with Django failed

I didnt initially use npm run build(used it after im done coding frontend) and i created my react frontend app inside my django project.

Trouble rendering results from searchbar in Django

Thank you. Please help me to understand my disconnect. The bigger aim for this is to then add different models to query from (i.e. not just search in projects, but also search by user). -
Cross-origin API call from a node.js server to a django server, need to edit data on the django side
For a project I am using a really old version of django (1.5.2). An app has been created using this version of django long time ago, and I am making a separate app that needs to make API calls to the django app. My separate app is in node.js/typescript. From my node app, I need to be able to POST some data to the django app. I have created the new API inside the django app, and it works internally. If I try to call the endpoint from my node app, it does not work - the method is called, but the posting part does not work as it looks for authentication and since I sent the request from the node app, the user shows up as AnonymousUser, who is non-authenticated. For APIs that do not require POST (just GET), I can access the django API endpoints from node since I defined CORS MiddleWare in the django app. I was wondering how I might be able to POST information from node app to the django app, and also authenticate user if the user is logged into the django app from another tab. -
Авторизация в андроид приложении
Я недавно начал изучать разработку под андроид на kotlin. Пишу небольшое клиент-серверное приложение. Серверная часть на Django готова и работает. Теперь прикручиваю интерфейс. Есть несколько вопросов: Я уже умею сделать запрос с логином и паролем. В ответ, если всё хорошо, Django присылает куки, в которых есть SCRF токен, id сессии, время жизни токена и сессии. Как мне сохранять эти куки в приложении для последующего использования? При открытии приложения мне надо как-то понимать, авторизован ли пользователь. Как это правильно сделать? Думал просто проверять наличие сохраненных куки, если всё с ними ок, значит авторизован. если их нет или время жизни закончилось, то снова запрашивать логин и пароль. Но может есть более православный способ? Есть данные, которые требуется синхронизировать с удаленной БД (например, список городов). Как это лучше реализовать? SQLLite и при открытии приложения синхронизировать все необходимые данные? Или есть более православный способ? -
