Display all of a Users info on the one page within Admin
My Users have both a ONE-ONE personal_information table, and a ONE-ONE previous_studies table. I know that I could use Inline to display both the personal_information and previous_studies tables on the one page if they had a relationship, but within the admin panel I am instead wanting to click a User, then see both their personal_information and previous_studies (at the moment I need to access the User, personal_information and previous_studies on different pages). Any pointers on how to accomplish this would be greatly appreciated. Thank you. -

Select a specific button in Javascript/AJAX
I have a list where a user can save various items in a Django app. Next to each items I have a button that can be used to delete this item. Items are stored in a database and are displayed with a for loop. The problem is whatever button I press, the first one is selected and deleted. I am new to JavaScript but I do understand that my issue is coming from my var.product selector because .val() returns the first element that matches ('.substitut'). I have tried to tweak a little with $(this) but with no luck... How can I select each product in each button individually? My HTML: {% for saved in saved_list %} <form class="form_id" method='post'>{% csrf_token %}{{ saved.id}} <button class='substitut' value='{{ saved.id}}'><i class='fas fa-trash'></i></button> </form> {% endfor %} My AJAX: $(".form_id").on('submit', function(event) { event.preventDefault(); var product = $('.substitut').val(); console.log(product); var url = '/register/delete/'; $.ajax({ url: url, type: "POST", data:{ 'product': product, 'csrfmiddlewaretoken': $('input[name=csrfmiddlewaretoken]').val() }, datatype:'json', success: function(data) { if (data['success']) console.log(product); $("#fav_list").load(location.href + " #fav_list > *"); } }); }); -

Django Rest Framework using Viewsets with different renderers
does it make sense to use Django Rest Framework also to render my HTML Code with Bootstrap and so on...? If no, what is the best solution to split the API endpoints and HTML view?

Both API and HTML rendered version are supposed to run on the same machine. Thanks in advance -

Why is Django migration not migrating table?
My django migration is not working properly. Out of three models I altered one model(table) in the initial version of my app and ran the makemigrations and then the migration command but the migration for that particular table did not happen properly so I thought there was some problem with the app. I deleted the table from the database and also created a new app and copied all the code from the first app to this one (including the code in the models, views, etc.). But when I use the migration commands, I still do not see the table in the database. The commands I use are python manage.py makemigrations python manage.py migrate Can anyone please help? -
