Django filter an already prefetched query set
I am using Django Rest Framework to get the data I use for the page. The Json is nested and contains a list of cards and their details. This use to create a table of cards on my page. I am trying to create a filter for this table and have manage to get it working if the user was to filter the data for one filter. However if the user wanted to filter by two fields it doesn't work and just filters by the last filter used. I know this is because when the code goes through the if statements I am using a new queryList of data rather than the already filtered queryList. However I cannot seem to filter the queryList. I would like to filter by card name and card type.

Unable to login to Heroku admin panel after successfully creating superuser
I am trying to create a superuser for a Django website that I have deployed on Heroku via Github. I did this locally by running the console locally for my Heroku app as shown in the image below. I followed the prompts after typing the command 'python manage.py createsuperuser' and got a message stating that the superuser was created successfully. However, when I opened the app again and trying to access the admin panel using a staff account I got a message asking me to type the correct credentials for a staff account. The superuser credentials were not recognized when I tried to login as a regular user either. I ran migrations using the command python manage.py makemigrations; python manage.py migrate before creating the superuser and afterwards but every time I got a message saying that there are no migrations to apply. Can someone please help me fix this issue? Thank you. -

How can I access images in my aws s3 bucket in a django html tag?

Saving API Information Into a Database - Using Django and Fetch API in Javascript
I'm new to APIs with Javascript and Django. I have a project where an API is called in Javascript, and it gets weather information for a specific location (the user types the location into a form first). Currently it does not save the weather info to the database. If the user clicks 'add to favorites' for the location, only then I want to save that info to the database. My question is, would I use a PUT request for this? Also, would I need a totally different fetch request for this, or would I be able to take the one I already have, and just get that data somehow. I'm assuming to save it to the database I would probably need a separate fetch request using PUT, because I only want it to save when the user clicks a button. Here is what I have for the API to get the weather data (this works correctly but this does not save to the database yet). function hi() { function temperature(input) { const myKey = "private"; const api = `https://api.openweathermap.org/data/2.5/weather? q=${input}&lang=en&appid=${myKey}&units=metric`; return fetch(api).then(function(response){ let data = response.json(); console.log(data); return data; }) .catch(error => { console.log('Error:', error); }) } Any guidance is … -
