How do I include username (<str:username>) in my react native Endpoint
Please im learning react native and I am stuck, my problem is that I need to be about to use something like this in my react native (API): const endpoint = "/users/<username>/"; const getUser = () => client.get(endpoint); So the gist is, I want to dynamically pass the user's username in there, because thats the only way to get the details from the backend (REST API), When i use POSTMAN and get this http://127.0.0.1:8000/api/users/*username* it returns the needed data, but when I try that, even putting the username manually it doesnt work . Secondly, is there a way to get the user's username from jwt token and pass it into the react native endpoint. Id share my code below, Please bear with me: API URL PATH IN DJANGO: path('<str:username>/', profile_detail_api_view), path('<str:username>/follow', profile_detail_api_view), API CALL IN REACT NATIVE: import client from "./client"; const endpoint = "/users/que/"; (FOR INSTANCE HERE IM PASSING THE USERNAME DIRECTLY TO TEST) const getUser = () => client.get(endpoint); export default { getUser, }; PAYLOAD ON JWT SAMPLE: { "token_type": "access", "exp": 1611483456, "jti": "47907077556234bd9b6a9fa330f5ee", "user_id": 2 } I have tried a direct endpoint (blog) and it works, but that user part doesnt even though its the same … -
How to modify the form field types in the django CreateView form
I have a model that has a couple of date fields. I am using the CreateView along with a template. In the template, I am doing fairly standard code {% extends 'instructor_base.html' %} {% load crispy_forms_tags %} {% block title %} New Section {% endblock %} {% block content %} <h1>New Section</h1> <form method="post"> {% csrf_token %} {{ form|crispy }} <button class="btn btn-success ml-2" type="submit">Save</button> </form> {% endblock %} However, when the form displays, the two date fields in the model are displayed as text boxes in the form. I would like them to display as date type. After several hours of going through documentation and tutorial sites, I can not figure out how to accomplish this. Everything I find is on how to override CreateView itself and not the form that goes with it. Any help with this would be greatly appreciated. -
Nginx stopped and failed to restart - open() "/run/nginx.pid" failed
I am running my django apis, deployed on Ubuntu 18, on Nginx and running via Supervisor. I am using Certbot for SSL certs and this is the only web service running on this webserver.

Implement Page/Google-Login Counter with Django and Cookies?
I want to keep track: 1.) How many visitors went on my homepage 2.) How many logged in with the Google button For now I simply created with python a django-model: id url visitor_counter google_login_counter Everytime someone visits a page with the url x, it increases the visitor_counter. Everytime someone logs in with Google on the page x, it increases the google_login_counter. So far, so good, but now I have the problem, that if the user reloads the page, the counter increases again. I want to prevent this and wanted to ask what is the best solution? I was thinking about using cookies to check, if the user was already on the page? Is there a better solution or should I go with cookies? -

How do I play only a portion of a video stored on AWS?
I have videos hosted on AWS S3 and ideally I would access them via something like <video muted autoplay loop><source src="https://mybucket.aws.com/videos/test.mp4#t0,15"></source></video>, causing only a certain part of the video to play and have it on loop. The issue is that the bucket is not public and so involves generating a pre-signed URL. I am using Django and boto3 in order to generate the pre-signed URL, but as soon as I attempt to insert #t0,15, it fails (either the # and , will be decoded, the #t0,15 string will be removed or the URL will return access denied, depending on what was attempted). How might I go about this? -
