Maximum update depth exceeded on django instance deletion
When trying to delete the model tenantJobCategory I'm seeing a weird error message: RecursionError: maximum recursion depth exceeded The problem only exists whenever the tenantJobCategory has an active FK relationship to a profile instance (if it doesn't have that the deletion works fine). This is the profile: class Profile(models.Model): uuid = models.UUIDField(primary_key=True, editable=False, default=uuid.uuid4) tenant_job_category = models.ForeignKey('job_categories.TenantJobCategory', null=True, blank=True, on_delete=models.SET_NULL) should_auto_promote = models.BooleanField(default=False) should_manual_promote = models.BooleanField(default=False) __original_should_auto_promote = None __original_manual_promote = None def __init__(self, *args, **kwargs): super().__init__(*args, **kwargs) self.__original_should_auto_promote = self.should_auto_promote <-- this seems to be the cause self.__original_manual_promote = self.should_manual_promote <-- this too def save(self, *args, **kwargs): if self.should_auto_promote != self.__original_should_auto_promote: should_auto_promote_change.send(sender=self.__class__, instance=self) if self.should_manual_promote != self.__original_manual_promote: should_manual_promote_change.send(sender=self.__class__, instance=self) super().save(*args, **kwargs) I've marked two lines that I think, are causing the error (when I delete them, it works fine, if I delete only one of them, it also works). Maybe someone ran into this problem before and knows how to fix it? Thanks! -
How to select same object twice in Django ManyToMany Field

Django Model Classes
I have three model classes, identity, record, and times chedule. Identity is related to record using employee_id with length of 20 chars. And times chedule is related to record thru emp_time_sched field. Running migrate, django.db.utils.DataError:value too long for type character varying(3) error. Checked the table attributes, record.emp_type_sched has 20 chars. I include max_length=3 and still same error. -
Django: Call and edit model from template
I'm using Django for a simple web app where tasks have milestones. When clicking a milestone, it should be marked completed. I'm not sure how to change the completed attribute from my template. This is my milestone model, where I define a function Milestone.complete that I'm trying to call from the template (without success). class Milestone(models.Model): name = models.CharField(max_length=200) task = models.ForeignKey(Task, on_delete=models.CASCADE) completed = models.BooleanField(default=False) def complete(self): self.completed = True My template looks like this: ... {% if task.milestone_set.exists %} <div class="card"> <div class="card-header">Milestones</div> <ul class="list-group list-group-flush"> {% for milestone in task.milestone_set.all %} <li class="list-group-item"> {{ milestone.name }} {% if not milestone.completed %} {# <a href="{{ milestone.complete }}" class="btn btn-primary">Completed</a>#} <button type="button" class="btn btn-success" onclick="{{ milestone.complete }}">Completed</button> {% endif %} </li> {% endfor %} </ul> </div> {% else %} <p>task has no milestones</p> {% endif %} ... Calling milestone.complete works neither from the a link element nor from the button. The latter gives me Uncaught ReferenceError: None is not defined in the console and nothing happens. I also thought about how to implement the same function in a view, but didn't know how. -

How can I get the previous URL in Django?
My code looks like this, I hope you will understand my logic. def home(request): if request.method == 'POST': return redirect('first-round') return render(request, 'home.html') def firstRound(request): # checking current url is redirected from home or not if request.META.get('HTTP_REFERER') == '/': if request.method == 'POST': return redirect('second-round') return redirect(request, 'first-round.html') else: return redirect('/') def secondRound(request): # checking current url is redirected from first-round or not if request.META.get('HTTP_REFERER') == '/first-round/': if request.method == 'POST': return redirect('third-round') return render(request, 'second-round.html') else: return redirect('/') def thirdRound(request): # checking current url is redirected from second-round or not if request.META.get('HTTP_REFERER') == '/second-round/': if request.method == 'POST': return redirect('login') return render(request, 'third-round.html') else: return redirect('/') request.META.get('HTTP_REFERER') return full path.

django.urls.exceptions.NoReverseMatch: Reverse for 'foo-list' not found. 'foo-list' is not a valid view function or pattern name
I've got the message Reverse for 'receptionop-list' not found. 'receptionop-list' is not a valid view function or pattern name. in one of my test cases when trying to do the following: reverse('receptionop-list') Note: I have also tried reverse('receptionops-list') I've got it set in my urls like this: router.register(r'receptionops', views.ReceptionOperationViewSet) What's weird for me, is the fact I've got also a router.register(r'reception', views.ReceptionViewSet) registered in the same app, and using reverse('reception-list') works perfectly. Does anyone know what's going on here? (If needed, I can provide some further information) Thanks! -
Configuring httpd.conf with python Django and mod_wsgi : how to configure so I can access to my url like www.example.com?
I'm working on new personal project that consist on developing a website with python Django framework. I'm using macOS High Sierra system and I'm trying to follow python tutorial for that. First we need to configure environment with apache httpd server and mod_wsgi module. I could display "Hello world" script with mod_wsgi application script but I get it with http://localhost url instead of http://www.example.com url... Also, I'm trying to configure it with virtual environment. The question is how do I need to do into httpd.conf file for that ? Thank you in advance for your help Tony Here is the main configuration for my virtual host : <VirtualHost *:80> ServerName www.example.com ServerAlias example.com example # Chemin a partir duquel le serveur va servir les fichiers, racine a partir de laquelle nous pourrons consulter depuis internet DocumentRoot /Users/username/Desktop/example/Site # Etapes de configuration du module mod_wsgi. # Définie le point d'entrée via le wsgi WSGIScriptAlias / /Users/username/Desktop/example/Site/wsgi-scripts/wsgi.py # Configuration du monde Daemon WSGIDaemonProcess example.com python-home=/Users/username/.local/share/virtualenvs/example-P5vj6Ml3 python-path=/Users/username/Desktop/example WSGIProcessGroup example.com <Directory /Users/username/Desktop/example/Site/wsgi-scripts> <IfVersion < 2.4> Order allow,deny Allow from all </IfVersion> <IfVersion >= 2.4> Require all granted </IfVersion> </Directory> <Directory /Users/username/Desktop/example/Site/wsgi-scripts> <Files wsgi.py> Require all granted </Files> </Directory> </VirtualHost> -
How to use the email field from a django-allauth table as username for authentication?
I'm using Django 3.1.1 with Django-allauth to handle user authentication. Creating a user makes entries in these 3 tables: auth_user account_emailaddress account_emailconfirmation Since usernames are not needed in my application I inherited from the User model to accept an email address instead: from django.contrib.auth.models import AbstractUser class User(AbstractUser): """User model.""" username = None email = models.EmailField(_('email address'), unique=True) USERNAME_FIELD = 'email' REQUIRED_FIELDS = [] objects = UserManager() This worked like a charm. However I noticed it makes absolutely no sense to have email addresses stored in auth_user at this point, because allauth already stores them in account_emailaddress. I noticed a foreign key already exists from the field user in account_emailaddress to auth_user: class EmailAddress(models.Model): user = models.ForeignKey(allauth_app_settings.USER_MODEL, verbose_name=_('user'), on_delete=models.CASCADE) email = models.EmailField(unique=app_settings.UNIQUE_EMAIL, max_length=app_settings.EMAIL_MAX_LENGTH, verbose_name=_('e-mail address')) Is it possible to make the USERNAME_FIELD variable afield from the account_emailaddress table instead or are there different/better practices? Also, it would be nice if this change would work with the manage.py createsuperuser script, so I can still create an admin account from the console. Thanks in advance! -
Deploying React + Django on Digital Ocean or another Cloud Service
I'm planning to develop a Django web application that extended with the DRF as well as Frontend will be powered by React js. Right now my selection for the deployment of the project is the Digital Ocean platform. I'm ok with Django deployments with the Digital Ocean, but I'm confused when it comes to django+React because both the technologies have two different servers running. So I need to know how to run Django and React in the same server. Please if anyone is aware of this or if there is clear documentation mention it out Thanks. -

Should I always use super().clean() when overriding clean() method on a modelform in Django
I have some custom validation in my model, as well as in the modelform in Django project. As I understood this explanation form official Django docs I always have to call super().clean() on modelform clean method, if I want to preserve the validation in the model, like this: class BookForm(forms.ModelForm): has_sequel = forms.BooleanField(initial=True) class Meta: model = Book fields = ['author', 'length', 'has_sequel', 'sequel'] def clean(self): super().clean() if self.cleaned_data['has_sequel'] and self.cleaned_data['sequel'] is None: raise ValidationError('You should indicate the sequel if the book has one.') However, if I don't use super().clean() it works perfectly. Now I am confused, do I need to use super().clean() or not? Note: I used code from this answer for simplicity. -
How to do i validate a password in a login form in Django
I have a login form in which i want to validate if the password is correct. And I try to do it using the clean method. In my form class i am using the clean method like so def clean(self): cd = self.cleaned_data print(self.username) # to debug actual_password = Person.objects.get(username=self.username).password if cd.get('password') != actual_password: self.add_error('password', 'That is not the correct password!') return cd This is the view for the login page: def user_login(request): if request.method == 'POST': form = PersonLoginForm(request.POST) if form.is_valid(): username = form.cleaned_data['username'] password = form.cleaned_data['password'] user = Person.objects.get(username=username) if user.password == password: return redirect('all-users/') print(form.errors) form = PersonLoginForm() context = { 'form': form, 'title': 'Login' } return render(request, 'index/login.html', context) Currently i am using this if statement to check if the password is correct: if user.password == password:.

I'm trying to figure out a way to have different CORS rules based on the backend endpoint frontend would hit. So I can have /api endpoint with a CORS domain whitelist and /public-api without a CORS domain whitelist.

I've looked at django-cors-headers library, but it's regex configuration CORS_ORIGIN_REGEX_WHITELIST = [] works to let requests FROM a list of domains through. I'm looking for a way to have a regex to let requests TO my endpoints through or not. -

view: class ChartAPIView(RetrieveAPIView): serializer_class = ChartSerializer queryset = Chart.objects.prefetch_related('attendees__person').all() def get_object(self): user = self.request.user last_updated = user.profile.data_last_updated user_events = self.queryset.filter(user=user).order_by('-created') data = { 'total': user_events.count(), 'last_updated': last_updated, "chart_data": user_events } return type('DashboardData', (), data)() Serializer: class DashboardSerializer(serializers.Serializer): total = serializers.IntegerField(read_only=True) last_updated = serializers.DateTimeField(read_only=True) chart_data = EventSerializer(read_only=True, many=True) Result: { "total": 2, "last_updated": "2020-09-22 04:49:25", "chart_data": [ { "title": "Daily Stand-up", "organizer": "mailbox@phanig.com", "duration": "0:30", "attendees": "soubhagyakumar666@gmail.com, mailbox@phanig.com", "created": "2020-08-25 06:11:54", "updated": "2020-09-17 04:50:25" }, { "title": "Daily Stand-up", "organizer": "mailbox@phanig.com", "duration": "0:30", "attendees": "soubhagyakumar666@gmail.com, mailbox@phanig.com", "created": "2020-08-25 06:11:54", "updated": "2020-09-17 04:50:25" }, { "title": "Daily Stand-up", "organizer": "mailbox@phanig.com", "duration": "0:30", "attendees": "soubhagyakumar666@gmail.com, mailbox@phanig.com", "created": "2020-08-25 06:11:54", "updated": "2020-09-17 04:50:25" } ] Here is my code and results i am getting . But, before sending result to browser i wants to do some modification Is there any way we can achive that. Basically i wants to modify user_events data by passing it to a utils function. Please have a look. Expected result: [{'created': '2020-08-24', 'duration': 510}, {'created': '2020-08-25', 'duration': 1260}] I have already the function which is converting to it but, as the user_events is a query set i amgetting error while getting the key.
