Django 3: Customizing Textfield in admin
I am trying to customise the admin textfield in admin class PostAdmin(admin.ModelAdmin): formfield_overrides = { models.TextField: {'widget': AdminMarkdownxWidget (attrs={'rows': 5, 'cols': 100, 'style': ' font-size: 1.5em; font-family: HelveticaNeue;'})}, } admin.site.register( Post, PostAdmin) In this example both rows and style is applied correctly but cols: parameter is ignored. I suspect this is bug in Django 3 but I am not sure. How would I customise the standard textfield in admin (no AdminMarkdownxWidget as in the above example) ? -
Attribute to override generic class based form and use a custom form?
I have the following form in forms.py: class JobForm(ModelForm): class Meta: model = Job fields = ['title', 'description'] widgets = {'title': TextInput(attrs={'class':'form-control'}), 'description': Textarea(attrs={'class':'form-control'}) } is there a way I can tell this view (and the CreateView) to use the form above: class JobUpdateView(UpdateView): model = Job fields = ['title', 'description'] template_name = 'job/edit_job.html' I'm just getting into using class-cased views and feel like this should have been easy to find with a quick search. Am I missing the point here, are you supposed to not have to define a custom for in forms.py if you are using class-based views? -

How to validate field with django autocomplete light
I'm using django autocomplete light to let the user either search for an existing badge_id or create a new badge with the specified badge_id. My models: class User(models.Model): badge = models.ForeignKey(Badge, on_delete=models.CASCADE) first_name = models.CharField(max_length=20, blank=True, null=True, verbose_name=_('first name')) last_name = models.CharField(max_length=20, blank=True, null=True, verbose_name=_('last name')) class Badge(models.Model): badge_id = models.CharField( primary_key=True, max_length=6, validators=[ RegexValidator( regex='^[0-9]{6}$', message="Badge id must be 6 digits.", code='nomatch' ) ], ) My UserForm: class UserForm(forms.ModelForm): class Meta: model = User fields = ( 'badge', 'first_name', 'last_name', ) widgets = { 'badge': autocomplete.ModelSelect2( url='badge-autocomplete', forward=["badge"], ) } My view for dal: class BadgeAutocomplete(autocomplete.Select2QuerySetView): def get_queryset(self): if not self.request.user.is_authenticated: return Badge.objects.none() qs = Badge.objects.all() badge = self.forwarded.get('badge_id', None) if badge: qs = qs.filter(badge_id=badge) if self.q: qs = qs.filter(badge_id__istartswith=self.q) return qs With this in place, validation is not working and this leads to two problems: I can create a badges with less than 6 digits (despite my model validator) Entering more than 6 digits raises a DataError server side but nothing shows on the frontend Any idea how to fix that? -
Rename django custom permissions
I'm working with django 2.0 app and going to update django version to 3.0. But in my project there are few custom permissions named like view_modelname. class MyConcreteModel(models.Model): model_field_1 = models.CharField(max_length=100, blank=False) # other fields class Meta: permissions = ( ("view_myconcretemodel", "Can see available device interfaces"), ) In django 3 (since v 2.1) such kind of permissions are default. So I got conflict with permission names. Now I'm trying to rename custom permissions before updating django version. class MyConcreteModel(models.Model): model_field_1 = models.CharField(max_length=100, blank=False) # other fields class Meta: permissions = ( ("user_view_myconcretemodel", "User can see available device interfaces"), ) After migration 'new' (with new names) permissions were created in DB. But old permissions still there and all users have old permissions (with old names like view_myconcretemodel). Obviously I need 'new' permissions for all users. Is there possibility simple to rename permissions or give 'new' permissions to relevant users (according to 'old' permissions), and do it automatically? -

How to render django formset in a grid layout
I have the following forms that will display several forms from a formset. <form method="POST" enctype="multipart/form-data" style="margin-left: 40px; margin-right: 40px"> {% csrf_token %} {{ formset.management_form }} {{ formset.non_form_errors }} {% for forma in formset.forms %} {{ forma }} {% endfor %} <input class="btn bg-success" type="submit" value="Update" /> When I use this layout all the forms in the formset are displayed vertically: Form 1 Form 2 Form 3 Form 4 ... ... ...

FileHandler doesn't write into the file
I need a logger in Django which writes to logs/realestates/realestate.pk/info.log. To be able to do this I'm creating logger dynamically. def get_realestate_logger(realestate): logger = logging.getLogger(f'engine.realestate.{realestate.pk}') logpath = realestate.get_log_path() # checked, it's ok logdir = os.path.dirname(logpath) if not os.path.exists(logdir): os.makedirs(logdir) handler = RotatingFileHandler(filename=logpath, backupCount=0, maxBytes=1024 * 1024) handler.setLevel(logging.INFO) handler.setFormatter(logging.Formatter(fmt=settings.LOGGING_VERBOSE_FORMAT, style='{')) logger.addHandler(handler) return logger And in realestate def save(self, refresh_status=True, **kwargs): super().save(**kwargs) logger = self.get_logger() logger.info('Created') def get_logger(self): return get_realestate_logger(self) The problem is that it doesn't write anything into the info.log file. Since propagation=True, it writes Created into the main log file. Just info.log doesn't contain anything. Where is the problem? -

How should I be implementing user SSO with AAD in a Django application (using the Django Microsoft Authentication Backend module)?
I'm developing a Django (2.2.3) application with Django Microsoft Auth installed to handle SSO with Azure AD. I've been able to follow the quickstart documentation to allow me to log into the Django Admin panel by either using my Microsoft identity, or a standard username and password I've added to the Django user table. This all works out of the box and is fine. My question put (really) simply is "What do I do next?". From a user's perspective, I'd like them to: Navigate to my application (example.com/ or example.com/content) - Django will realise they aren't authenticated, and either automatically redirect them to the SSO portal in the same window, or redirect them to example.com/login, which requires them to click a button that will open the SSO portal in a window (which is what happens in the default admin case) Allow them to sign in and use MFA with their Microsoft Account Once successful redirect them to my @login_required pages (example.com/content) Currently, at the root of my navigation (example.com/), I have this: def index(request): if request.user.is_authenticated: return redirect("/content") else: return redirect("/login") My original idea was to simply change the redirect("/login") to redirect(authorization_url) - and this is where my problems start.. … -

Capture the NTLM username and pass as a parameter to a Stored Procedure

Django csrf follow up ajax requests not working
