Problems with Django Avatars
I have a problem in my django app and when I edit a user my avatar photo is deleted and returns to the default one, I think the problem is in the views because it works correctly if I load the values from the django admin, If you could help me, I would appreciate it very much. This is the code: Views: @login_required def editar_user(request): mensaje = "" if request.method == "POST": extension_logued_user, _ = Avatar.objects.get_or_create(user=request.user) FormularioUser = NuestraEdicionUser(request.POST, request.FILES) if FormularioUser.is_valid(): logued_user = request.user #intancia del Usuario logued_user.email = FormularioUser.cleaned_data['email'] logued_user.first_name = FormularioUser.cleaned_data['first_name'] logued_user.last_name = FormularioUser.cleaned_data['last_name'] extension_logued_user.imagen = FormularioUser.cleaned_data['imagen'] extension_logued_user.link = FormularioUser.cleaned_data['link'] extension_logued_user.more_info = FormularioUser.cleaned_data['more_info'] if FormularioUser.cleaned_data['password1'] != '' and `FormularioUser.cleaned_data['password1'] == FormularioUser.cleaned_data['password2']:` logued_user.set_password(FormularioUser.cleaned_data.get("password1")) else: mensaje = "" if extension_logued_user.imagen is None: pass logued_user.save() extension_logued_user.save() return render(request, "index/index.html", {"mensaje":mensaje}) else: extension_logued_user, _ = Avatar.objects.get_or_create(user=request.user) return render(request, "EditUser.html", {"FormularioUser":FormularioUser,"mensaje":mensaje}) extension_logued_user, _ = Avatar.objects.get_or_create(user=request.user) FormularioUser = NuestraEdicionUser( initial={ 'first_name': request.user.first_name, 'last_name': request.user.last_name, 'email': request.user.email, 'imagen': extension_logued_user.imagen, 'link': extension_logued_user.link, 'more_info': extension_logued_user.more_info, } ) return render(request, "EditUser.html", {"FormularioUser": FormularioUser, "mensaje":mensaje}) Template: {% extends 'index/index.html' %} {% load static %} {% block Encabezado %} <h1>Tu cuenta</h1> {% endblock Encabezado %} {% block PruebaTemplate %} {% if msj %} {{msj}} {% endif %} {% if … -

Django-rest-framework api permission AllowAny authentication failed
I have someViews like below: class SomeView(generics.ListAPIView): serializer_class = SomeSerializer permission_classes = [AllowAny] settings.py: REST_FRAMEWORK = { 'DEFAULT_PERMISSION_CLASSES': ( 'rest_framework.permissions.AllowAny', ), ... 'DEFAULT_AUTHENTICATION_CLASSES': ( 'rest_framework_simplejwt.authentication.JWTAuthentication', ), ... } And When I request without any Authorization header it works fine. But When I add Bearer Authorization header it response "detail": "Given token not valid for any token type", "code": "token_not_valid", I gave permission_classes=[AllowAny]. Why? I thought there is no difference between sending or not sending tokens. Because I set permission_class=[AllowAny]. In ASP.NET there is no like this problems. In ASP.NET If I set AllowAny permission this endpoint open for everyone regardless of whether you send a Token or not. -

(DRF) How to make axios post request on nested object with reverse lookup for foreignkey as primary key

How to modify url in a django get request
I have a web page which displays some data (with get parameters to filter in the view) and I use a pagination. To go through the data i use a link to change the page in the paginator : <li class="paginator-data"><a href="{{ request.get_full_path }}?page={{ page_obj.next_page_number }}">Next</a></li> Here is the problem : url looks like that after browsing a few pages : http://127.0.0.1:8000/?page=2&page=3&page=4&page=5&page=6 The view is working well (It displays me the last page) but I got this ugly link. I tried something like that : request.GET.get = querydict (with querydict a QueryDict object with only one page data) But It didn't work. I also thought of parsing data in the template but maybe there is a better way. -

Send messages from Django to Ajax while processing the request
I'm making an AJAX call to a Django POST view. It's reading X files locally, and then sending back to the front-end (thanks to ajax), so the user can download them. Everything is working fine on this part, but i'd like to have some sort of "intermediate response", which would tell Ajax that the server has read one file. That way, i could create a loading bar on the front end while the server is processing the request. Is there any way to do it, using only Ajax and Django ? Here is my code, quite simplified, so you can understand better what I'd like it to do: Django: def downloadFiles_API(request): if request.is_ajax and request.method == "POST": requested_files = json.loads(request.body)['files'] for file in requested_files: # Handle file reading (this part works) # Here i'd like to tell the front end "File X has been loaded..." # Zip-ing all files, and send it as response return FileResponse(myZipFile) AJAX: $.ajax({ url: "/api/downloadFiles/", type: 'POST', contentType: "application/json; charset=utf-8", data: JSON.stringify({ "files" : filesThatTheUserWants, }), xhrFields:{ responseType: 'blob' }, success: function (response){ // Download the file in response (this works) }, // And what i'd like to add (it's NOT in my code): onProgress: … -
