Unable to to access Generic Views with JWT authentcation
I'm at a loss - I have a django backend and react frontend. On the frontend, I have a login page that sets a JWT token, and I use that token to query data from the django backend. This all works perfectly. But I also have direct views to these APIs via something simple as http://localhost:8000/tables/data which will just show me a default django view of these tables (ie: a paginated "select * from data" call) ... and hooked in through a genericListAPIView. Now, as I said, everything works fine when feeding it via a curl command (or postman, or whatnot). I get the JWT token, set it the Authorization access in the subsequent call to the API, and get the data back and do something with in in React. What I can't seem to figure out is how to hoo that same JWT token when calling trying to access the generic view. When I browse to it, I get HTTP 401 Unauthorized Allow: GET, HEAD, OPTIONS Content-Type: application/json Vary: Accept WWW-Authenticate: JWT realm="api" { "detail": "Authentication credentials were not provided." } Which I guess make sense since I'm not going through any React authentication. Yet, it's the same server. … -
Button doesn't work upon incorporating bootstrap table
After spending days agonizing over this error and looking for someone who might have had this same problem, I'm finally ready to just ask the question myself. I'm building an app on Django. My post button worked perfectly, but upon incorporating bootstrap-table, it doesn't work anymore. And by doesn't work anymore, it seems to have gone completely dormant -- no error logged in the console or terminal, it just looks like a button, but does absolutely nothing. Has anyone encountered a similar issue to this, and how did you fix it? If I take out data-toggle="table" in the table tag, the button works... but it completely messes up the styling, and I'd like to avoid that. Here is my template html: <table id="table" data-toggle="table" data-search="true" data-height="650" data-show-columns="true"> <thead> <tr> <th data-sortable="true">ID</th> </tr> </thead> <tbody> {% if df %} {% for i in df %} <tr> <form method="POST"> {%csrf_token%} <td value="{{i.ID}}"><input value="{{i.ID}}" name="dataId" type="text" class="form-control" aria-label="Large" aria-describedby="inputGroup-sizing-sm"></td> <td> <form method="POST"> <button type="submit" class="btn btn-secondary" name="updatePlacement">Save</button> </form> </td> </form> </tr> {% endfor %} {% endif %} </tbody> </table> and part of my view: def post(self, request): if "updatePlacement" in request.POST: print('hi') return render(request, "placement/index.html") -

submit select value from template to django form

Determine which DRF auth class authenticated successfully first
Let's say I have the following Django Rest Framework authentication class order: REST_FRAMEWORK = { "DEFAULT_AUTHENTICATION_CLASSES": [ "rest_framework.authentication.TokenAuthentication", "rest_framework.authentication.SessionAuthentication", "MyCustomAuthClass", ], ... } Per the docs: REST framework will attempt to authenticate with each class in the list, and will set request.user and request.auth using the return value of the first class that successfully authenticates. Within my view I want to know which class authenticated successfully. My use case is that I want to handle the third auth class differently for a specific endpoint. I'm currently re-authenticating which seems unnecessary and not performant: def get(self, request): if ( not TokenAuthentication().authenticate() and not SessionAuthentication().authenticate() and MyCustomAuthClass().authenticate(request): # do this else: # do something else Is there anyway to do that or is my approach the best option? -

How to validade traverse attributes in DRF Serializer
So, trying to be as brief as possible and to put my problem into context, I will tell you here my doubt. The problem is that I don't know how to serialize the data in a correct way.

Django: Delete A form with javascript
So for more context, I'm making a biolink website which means the issue is adding and removing links for your profile. As of right now, I have a working add function, heres the code: <div class="links-section"> <div class='linkform-container'> {{ link_form.management_form }} <div id='form_set'> {% for form in link_form %} <div class='linkform'>{{ form }}</div> {% if formset.can_delete %} <li>{{ form.DELETE }}</li> {% endif %} {% endfor %} </div> <div id="empty_form" style="display:none"> <div class='linkform'>{{ link_form.empty_form }}</div> </div> <div class="add-remove-button-container"> <i class="fa-solid fa-plus add-link-button link-button" type="button" value="Add More" id="add_more"></i><i class="fa-solid fa-xmark remove-link-button link-button" type="button" value="Remove More" id="remove_more"></i> </div> <script> $('#add_more').click(function() { var form_idx = $('#id_form-TOTAL_FORMS').val(); $('#form_set').append($('#empty_form').html().replace(/__prefix__/g, form_idx)); $('#id_form-TOTAL_FORMS').val(parseInt(form_idx) + 1); }); </script> But I need a way to delete a formset. Preferably this can be javascript and removable with a click on a button. PS: I'm VERY sorry that this isn't explained well because im not very good at explaining, but i'm hoping its understandable and it means a lot because I can't find the solution anywhere else
