Django rest framework pagination asking for authentication each time?
i have created an ListApiView with django rest framework. i have allotted isAuthenticated permissions for the users and it is processing well. i want to allow paginations in to ApiView. ok i have set paginations permission globally. when i want to render data in to html template using JavaScript the rest framework asking me for the user authentication which i have already authenticate. if i disable the paginations permission the data is rendering well but when i enable the paginations the system asking me again authentications. can anybody know where i make the mistake? api_viwes.py class ApprovedArticleList(ListAPIView): queryset = Article.objects.all() serializer_class = NewsSerializer filter_backends = (SearchFilter,) search_fields = ('title', 'author__username', 'content', 'category__name') settings.py REST_FRAMEWORK = { 'DEFAULT_PERMISSION_CLASSES': ( 'rest_framework.permissions.IsAuthenticated', ), 'DEFAULT_AUTHENTICATION_CLASSES': ( 'rest_framework.authentication.BasicAuthentication', ), 'DEFAULT_PAGINATION_CLASS': 'rest_framework.pagination.PageNumberPagination', 'PAGE_SIZE': 2, } -

Django - Catching UNIQUE costraint failed
I have a class method for creating a slug from title for url, which must be unique. In case the title is taken I would like to add id at the start of the slug, but my exception block is completely ignored and I have tried already with quite a few options. class Book(models.Model): title = models.CharField(max_length=200) slug = models.SlugField(max_length=255, unique=True, null=True, blank=True) def save(self, *args, **kwargs): try: self.slug = slugify(self.title) except IntegrityError as e: if 'UNIQUE constraint failed' in e.args[0]: self.slug = slugify(str(self.id) + "-" + self.title) super(Book, self).save(*args, **kwargs) -
Django Ajax Call and response with Render
I am new to Python and Django and I would like to do a task where the user have 2 drop downs. Item drop down and Machine drop down. The Machine drop down is filled depending on the selection of the Item drop down and at the same time a table is refreshed depending on the selection of the 2 drop downs. I was thinking to do so, from JavaScript, onChange of Item drop down, I use an AJAX function which calls a function in view.py by providing Item selection as show in the Javascript part. On return of the Django function I use render return. Both the JavaScript and def load_machines seems to work fine but the return render(request, 'home.html', {'machines': machines}) is calling home.html but machines is empty. How shall I tackle such problem, any hint what to look at? JavaScript part <script> $("#exampleFormControlSelect1").change(function () { const url = $("#mainForm").attr("data-machines-url"); const itemId = $(this).val(); $.ajax({ // initialize an AJAX request url: url, data: { 'itemId': itemId // add the item id to the GET parameters }, success: function (data) { // `data` is the return of the `load_cities` view function } }); }); </script> Django Part view.py def … -
How to use something like a logout required in django views?
I have a login and sign_up view like this: def sign_up(request): form = UserCreationForm() registered = False if request.method == 'POST': form = UserCreationForm(data=request.POST) if form.is_valid(): form.save() registered = True context = { 'form':form, 'registered':registered, } return render(request, 'users/sign_up.html',context) def login_page(request): form = AuthenticationForm() if request.method == 'POST': form = AuthenticationForm(data=request.POST) if form.is_valid(): username = form.cleaned_data.get('username') password = form.cleaned_data.get('password') user = authenticate(username=username,password=password) if user is not None: login(request,user) return HttpResponseRedirect(reverse('index')) context = { 'form':form, } return render(request, 'users/login.html',context) What I actually want is that if the user is not logged out first and tries to access the sign up or login page, they are redirected to the logout page to first logout. So, they can't access these 2 pages unless they are logged out. How can I do this? -

How to connect React to Django?
I am using reactJS as the frontend while Django at the backend. When I make a request from react to Django(react is running at http://127.0.0.1:3000 while Django is running at http://127.0.0.1:8000), Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at http://127.0.0.1:8000/api/categories. (Reason: CORS header 'Access-Control-Allow-Origin' missing). Most likely, it's occurring due to CORS issue. So I installed django-cors-headers and make following changes in my settings.py:- INSTALLED_APPS = [ 'django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', 'django.contrib.staticfiles', 'django_cleanup.apps.CleanupConfig', 'myapp', 'corsheaders' ] MIDDLEWARE = [ 'corsheaders.middleware.CorsMiddleware', 'django.middleware.security.SecurityMiddleware', 'django.contrib.sessions.middleware.SessionMiddleware', 'django.middleware.common.CommonMiddleware', 'django.middleware.csrf.CsrfViewMiddleware', 'django.contrib.auth.middleware.AuthenticationMiddleware', 'django.contrib.messages.middleware.MessageMiddleware', 'django.middleware.clickjacking.XFrameOptionsMiddleware', ] CORS_ALLOWED_ORIGINS = [ "http://127.0.0.1:3000" ] But the error still persists. How can I make it work? -
Where to put Django permissions logic?
I have a 'View' which is mostly contain a 'Form', I need one User-Group with edit-permission to see it and edit form, And another User-Group with just view-permission to only can view information, And they can't edit information. What is the best way to achieve this behavior? I'm aware of 'permission_required' decorator and 'PermissionRequiredMixin' mixin but they are effect on entire view which is not my goal. I guess i should use user.has_perm() but I'm not sure where to put the logic, in views or forms or somewhere else... -
Inlineformset_factory: validation failed (this field is required)

modelformset_factory duplicate queries issue
I want to know if there's a way to cache queryset when rendering each form of formset, like similar way as select_related. My formset made by modelformset_factory causes db hits for every form generated. If I have 100 instances, queries are dupliacated 100 times plus. I used select_related when I made queryset as an argument to formset, but it doesn't seem to cache it. views.py .... queryset=Allocate.objects.select_related('license').filter( date=date, license__number__range=(2101, 2105) ) # formset 설정 AllocateFormSet = modelformset_factory( Allocate, form=AllocateModelForm, extra=0 ) if request.method == 'GET': formset = AllocateFormSet(queryset=queryset) .... models.py class Allocate(models.Model): license = models.ForeignKey( 'license.License', verbose_name='차번', on_delete=models.CASCADE, ) morning_driver = models.ForeignKey( 'employee.Employee', verbose_name='오전기사', on_delete=models.CASCADE, related_name='morning_drivers', blank=True, null=True ) afternoon_driver = models.ForeignKey( 'employee.Employee', verbose_name='오후기사', on_delete=models.CASCADE, related_name='afternoon_drivers', blank=True, null=True ) forms.py class AllocateModelForm(forms.ModelForm): def __init__(self, *args, **kwargs): super().__init__(*args, **kwargs) self.label_suffix='' for key in self.fields.keys(): self.fields[key].required = False self.fields['license'].disabled = True license_qs = License.objects.filter(id=self.instance.license_id) self.fields['license'].queryset = license_qs self.fields['morning_driver'].queryset = Employee.objects.none() self.fields['afternoon_driver'].queryset = Employee.objects.none() When I see SQL section from django-debug-toolbar, it says I have quite many duplicate queries.

Django python regex to include dollar symbol in URL

Hiding some of the fields in django forms
I am using modelformse_factory, where I can set extra value, which corresponds to the number of file inputs, that are in my form. ImageFormSet = modelformset_factory(PostImage,form=ImageForm, extra=3) Can I somehow limit the fields to some number, lets say 1 and then show 2 other by clicking some button? So basically the form renders all 3 fields, but two of them are hidden until I press a button?
