Django contrib.auth.forms Bug? - get_invalid_login_error never reached
I was just about to subclass the login form of django.contrib.auth.forms: "class AuthenticationForm(forms.Form)" after dealing a bit with the code I was about to customize the user_is.active check in order to display a customized message at my login. I was wondering as I was not able to figure out at what point exactly the user_is.active really gets validated. The clean method does a call to another function called confirm_login_allowed but from my perspective this never gets reached?! I test against this with a user that is not active but I always get back self.get_invalid_login_error instead of confirm_login_allowed error message. Can smb. confirm that this is a bug or at least at what point confirm_login_allowed gets triggered ? def clean(self): username = self.cleaned_data.get('username') password = self.cleaned_data.get('password') if username is not None and password: self.user_cache = authenticate(self.request, username=username, password=password) if self.user_cache is None: raise self.get_invalid_login_error() else: self.confirm_login_allowed(self.user_cache) return self.cleaned_data def confirm_login_allowed(self, user): if not user.is_active: raise forms.ValidationError( self.error_messages['inactive'], code='inactive', ) def get_user(self): return self.user_cache def get_invalid_login_error(self): return forms.ValidationError( self.error_messages['invalid_login'], code='invalid_login', params={'username': self.username_field.verbose_name}, ) -

DRF filter of lookups in the HTML Forms
I am using Django 3.05, Django Rest Framework 3.11.0, Python 3.7 Background I have setup a an object level security model to ensure a User can only read/write data to an Organisation or Venue to which they have access. This is controlled through an OrganisationMembership mapping User to Organisation. To create or update an Venue a user must be assigned to the Organisation. This all works via the Django Rest Framework's API when used the way my application will access. It's taken a little setup but gives the desired permissions. However, I am also using the DRF's HTML Forms to test and I cannot find any mechanism to change the QuerySet to restrict access to the Organisation names in the drop down list The drop down list therefore incorrectly shows Top Secret Organisation data to which I am not permitted on the OrganisationMember +-----------+--------------+ | Raw Data | HTML Form | +----------------------------------------------+ + | | | Organisation: v☑︎ Org 2 - I have access (McDonalds) v | | v Org 1 - I have access (Burger King) v | | v Org 3 - I should not see (Top Secret) v | +-------------------------------------------------------------+ Screen grab here 1 Note attributes in … -

Uploading images to amazon cloudfront / S3 via python/django
I am uploading images on amazon S3 bucket, via django/python backend and I am using django-storages Image uploading was all working okay, with some minor delay, but now when I am trying to upload, it takes a few seconds, and then process breaks, saying, image didn't upload. I could see images on S3 bucket, however, ( I think because of this delay ) django doesn't update the uploaded file information on DB (Postgres), and frontend says, image didn't upload. So this is kind of break, and I am not sure how to fix this. Please help if anyone has faced similar issues. I have referred to other questions and articles, for example, but don't know if I should go for any optimization or if there is a simple way to fix this problem. -

Send ajax request to django and update html
I am writing a Web Application with Django that through ajax POST request executes on the server some code written in python, and should retrieve on the client side the output as a JSON and update the html partially with javascript. I can send the request to the server and execute the subprocess, also do i retrieve the JSON Data but not updated in the html but shown as a dictionary to the website without the html content. So the last part is not working, and i figured out that for the ajax request when i test it in the view function it returns false. Another Problem is that the subprocess has a File as output so I can not catch the stdout from the subprocess view.py: def call(request): call_form = Call(request.POST) print(request.is_ajax())->returns false? if call_form.is_valid(): purity_arg = call_form.cleaned_data['purity'] chr_sex = call_form.cleaned_data['chromosomal_sex'] command = "cnvkit.py call -m clonal --purity %s --drop-low-coverage %s" % ( purity_arg, chr_sex) process_call = subprocess.Popen(command.split(), stdout=subprocess.PIPE, stderr=subprocess.PIPE,cwd=sfs.path('cnv_app/call_CNS/'), universal_newlines=True) stdout, stderr = process_call.communicate() if process_call.returncode and stderr: output_call += stdout + '\n' output_err_call += stderr + '\n' else: output_call += stdout + '\n' process_call.poll() response = {'output_call': output_call, 'output_err_call': output_err_call} return JsonResponse(response) .html: <h2>Call</h2> <p>Given segmented log2 … -

How to translate only custom error messages in DRF?
In DRF all default error messages are already translated. But I need to translate my own error messages. What did I do: Put all my error messages into _(), where _ is gettext In settings set LOCALE_PATHS to locale folder Ran python manage.py makemessages -l ru That created .po file and here goes the first trouble. In the .po file are my messages and besides that there are a lot of default django messages which I don't want to translate. (I do not want to override the translation, I want to extend it) I translated my messages in the .po file, then I ran python manage.py compilemessages which created .mo file. And here is the second trouble. All my messages are now translated, but default DRF messages (they were not in the .po file, there were Django messages, not DRF) are not already translated, they are only in english (e.g. Authentication credentials were not provided, This field is required, etc.) -
