How do I set a ForeignKey based on the user account when I save a new element with the extra field of modelformset_factory?
I have two problems: 1) I would like to add a new player in extra field of the Formset but when I save it I have an IntegrityError because team = models.ForeignKey(Team, on_delete=models.CASCADE is not set. I need that the value of team is team=request.user.team but I don't know where to put this in my views.py or if I need to override some existing function. 2) When I render the site at the end of each form appear the string "Human ptr:"... how can I delete it? I have a form made with formset_factory rendered like this: team_area.html {% extends 'base_layout.html' %} {% block content %} <h1>Area Squadra</h1> <form method="post" action=""> {% csrf_token %} {{ player_formset.management_form }} {% for player_form in player_formset %} {% for field in player_form %} {{ field.label_tag }} {{ field }} {% endfor %} <br> {% endfor %} <input type="submit" value="Aggiorna"> </form> {% endblock %} And the view is managed by: views.py from django.shortcuts import render, redirect from skeleton.models import Player from django.contrib.auth.decorators import login_required from .forms import PlayerForm from django.forms import modelformset_factory # Create your views here. @login_required(login_url="/accounts/login/") def team_area(request): PlayerFormSet = modelformset_factory(Player, fields=('first_name', 'last_name'), extra=1) if request.method == "POST": player_formset = PlayerFormSet( request.POST, request.FILES, … -
Bitnami Django stack deploying an existing project issue
I am bit new to Bitnami django stack which I found is really useful to deploy a django project with much hassles. I have a project which is build in django so for deploying the project I tried to install the stack by downloading the bitnami django stack even though the installation went without error and was able to start the apache server the deployment of existing project seems to be throwing error. I tried the exact steps from https://docs.bitnami.com/oci/infrastructure/django/get-started/deploy-django-project/ but seems like it doesnot have full documentation for deploying existing project . It shows how to create a new project and run it. so I tried by replacing the demo project with the new project which i had created earlier that to went wrong by not working. So my question here is : How to deploy exactly in django stack for existing project ? How to install requirements to the python path(for that I found use_django_stack script but bit confused with the usage) ? How to migrate models ? How to activate virtualenv ? -
Django REST Framework, save to extra field on custom user model
Using Django REST Framework (DRF) I added a custom user model with one extra field. I have posted my code at the bottom. Now, when registering a new user ('/rest-auth/registration/') using DRF's graphical interface, I do get an extra input for the new model field. When I enter a value into this form input and hit POST, a new user is indeed created, but the extra field stays empty. I have been looking into how to get this to work, and found another SO question with a good example and answers, but the problem with this SO post is that the poster uses AbstractBaseUser as the class that his custom user models inherits from, and I want to use AbstractUser instead. (Why? Since I read that this is recommended, unless you truly understand what you are doing.) Because the poster in the other SO answer uses AbstractBaseUser, his solution seems to involve much more code and compliation than I need. So, can anyone tell advice me on how I can have the extra field also be filled during registration, when POSTing the correct data? users.models.py: from django.contrib.auth.models import AbstractUser from django.db import models class CustomUser(AbstractUser): preferred_locale = models.CharField(max_length=2, blank=True, null=True) … -
Django REST-Auth Password Reset Tokengenerator (Generates b36 uid on request, wants b64 uid on confirm)
I am completely confused by the django middleware available: I simply want to get password-reset (and later password-change) functionality running, using django with rest_auth on the backend and Vue on the frontend. Step 1: Requesting the Reset-Link via Mail Views So far I have made a CustomPasswordResetView: # project/accounts/views.py from rest_auth.views import PasswordResetView class CustomPasswordResetView(PasswordResetView): pass Serializers and a CustomPasswordResetSerializer: # project/accounts/serializers.py from rest_auth.serializers import PasswordResetSerializer class CustomPasswordResetSerializer(PasswordResetSerializer): email = serializers.EmailField() password_reset_form_class = ResetPasswordForm def validate_email(self, value): # Create PasswordResetForm with the serializer self.reset_form = self.password_reset_form_class(data=self.initial_data) if not self.reset_form.is_valid(): raise serializers.ValidationError(self.reset_form.errors) ###### FILTER YOUR USER MODEL ###### if not get_user_model().objects.filter(email=value).exists(): raise serializers.ValidationError(_('Invalid e-mail address')) return value def save(self): request = self.context.get('request') # Set some values to trigger the send_email method. opts = { 'use_https': request.is_secure(), 'from_email': getattr(settings, 'DEFAULT_FROM_EMAIL'), 'request': request, } opts.update(self.get_email_options()) self.reset_form.save(**opts) Settings.py In the settings.py I have these fields, which seem relevant to me for my problem: # project/vuedj/settings.py REST_AUTH_SERIALIZERS = { "USER_DETAILS_SERIALIZER": "accounts.serializers.CustomUserDetailsSerializer", "LOGIN_SERIALIZER": "accounts.serializers.CustomUserLoginSerializer", "PASSWORD_RESET_SERIALIZER": "accounts.serializers.CustomPasswordResetSerializer" } (The complete settings.py is attached at the bottom) URL patterns My urls already catch my API request in order to send the Password-Reset Email: # project/vuedj/settings.py urlpatterns = [ path('admin/', admin.site.urls), path('api/v1/', include('api.urls')), path('accounts/', include('allauth.urls')), path('', api_views.index, name='home') ] … -

How do I override the .update() method inside a custom manager class
How can I override the update() method of a django model inside a custom manager? I would like to modify the behavior of some methods(all(), update(), filter()) of a django model and I have tried to override using what my code down here suggests but nothing is happening. I have tried using QuerySet instead of inheriting from Manager but I am failing to override it properly as I am getting empty results all over the system. class undeletedObjectManager(models.Manager): def get_queryset(self): return super(undeletedObjectManager, self).get_queryset().filter(deleted=False) def update(self, *args, **kwargs): if "deleted" in args: # some logic here super().update(*args, **kwargs) the update() method isn't reached and I am guessing it is because I am not overriding the correct member. Is there a specific method name? in both Manager and QuerySet classes? How should I override them? -

Can I define classes in Django settings, and how can I override such settings in tests?
We are using Django for Speedy Net and Speedy Match (currently Django 1.11.17, we can't upgrade to a newer version of Django because of one of our requirements, django-modeltranslation). I want to define some of our settings as classes. For example: class UserSettings(object): MIN_USERNAME_LENGTH = 6 MAX_USERNAME_LENGTH = 40 MIN_SLUG_LENGTH = 6 MAX_SLUG_LENGTH = 200 # Users can register from age 0 to 180, but can't be kept on the site after age 250. MIN_AGE_ALLOWED_IN_MODEL = 0 # In years. MAX_AGE_ALLOWED_IN_MODEL = 250 # In years. MIN_AGE_ALLOWED_IN_FORMS = 0 # In years. MAX_AGE_ALLOWED_IN_FORMS = 180 # In years. MIN_PASSWORD_LENGTH = 8 MAX_PASSWORD_LENGTH = 120 PASSWORD_VALIDATORS = [ { 'NAME': 'speedy.core.accounts.validators.PasswordMinLengthValidator', }, { 'NAME': 'speedy.core.accounts.validators.PasswordMaxLengthValidator', }, ] (which is defined in https://github.com/speedy-net/speedy-net/blob/uri_merge_with_master_2018-12-26_a/speedy/net/settings/global_settings.py). And then in the models, I tried to use: from django.conf import settings as django_settings class User(ValidateUserPasswordMixin, PermissionsMixin, Entity, AbstractBaseUser): settings = django_settings.UserSettings (and then use attributes of settings, such as settings.MIN_USERNAME_LENGTH, in the class). But it throws an exception AttributeError: 'Settings' object has no attribute 'UserSettings' (but it doesn't throw an exception if I use there a constant which is not a class). This is the first problem. In the meantime, I defined instead: from speedy.net.settings import global_settings … -
Django ORM annotation with tree traversal
I'm using the django-mptt library to make categories for my project. The model is pretty simple: from django.db import models from mptt.models import MPTTModel, TreeForeignKey class Category(MPTTModel): name = models.CharField('Name', max_length=100, unique=True) color = models.CharField( 'Color', max_length=100, blank=True, null=True ) parent = TreeForeignKey( 'self', on_delete=models.CASCADE, null=True, blank=True, related_name='children' ) class MPTTMeta: order_insertion_by = ['name'] Category color is optional and should be inherited from parent. So just to illustrate: Main Category 1 (red) -> Subcategory 1 -> Subcategory 2 (blue) -> Subcategory 3 (yellow) -> Subcategory 4 Subcategory 4 has no color defined and it inherits subcategory 3 color (yellow). Subcategory 1 inherits color from Main Category 1 (blue), etc. In my view i have the root category and then build a tree using get_descendants(include_self=True). How can i annotate color for each category of <TreeQuerySet>? For one model i have the following method: @property def inherited_color(self): if self.color: return self.color return (self .get_ancestors(ascending=True, include_self=True) .filter(color__isnull=False) .values_list('color', flat=True) .first()) But when this method is called for a list of categories it results in a lot of database queries! This is an example from django shell: >>> category <Category: 3> >>> category.color is None True >>> category.get_family().values_list('name', 'color') <TreeQuerySet [('1', '#51DCFF'), ('2', None), … -

How to add resend interval to django activation emails?
I have set up my django backend to send the activation email (with activation link) to the user's email address provided at registration. But recently, I have been getting spam attacks where the user (or bot or whatever) requests the activation link continuously and increases the load on my email server. To counter this, how can I add a time delay/interval between successive requests for an activation email to the same email address? Should I create a custom view for this? if so, what view should I look at modifying and how can I add a time interval that say restricts the user from requesting 1 an activation link every 5 or 10 mins?
