Subscription Form using Django Allauth
I recently created a Django template using allauth for an Abstract User. I followed William Vincent’s best practices in his book and the settings according to the documentation but I’m currently stuck. I’d like to support multiple signup forms to create a user. The 2 signup forms I’d like to support are: Account creation, which uses the typical convention of: #my_project/setings.py AUTH_USER_MODEL = ‘users.CustomUser’ LOGIN_REDIRECT_URL = ‘home’ LOGOUT_REDIRECT_URL = ‘home’ ACCOUNT_SESSION_REMEMBER = True ACCOUNT_SIGNUP_PASSWORD_ENTER_TWICE = False ACCOUNT_AUTHENTICATION_METHOD = ‘email’ ACCOUNT_EMAIL_REQUIRED = True ACCOUNT_UNIQUE_EMAIL = True ACCOUNT_USERNAME_REQUIRED = False ACCOUNT_USER_MODEL_USERNAME_FIELD = ‘username’ ACCOUNT_USER_MODEL_EMAIL_FIELD = “email” A User Subscription Form (with simply email and no password), which uses what I came up with: #users/forms.py class CustomUserSubscribeForm(forms.ModelForm): class Meta: model = CustomUser fields = (‘email’, ) email = forms.EmailField( label=_(''), widget=forms.TextInput( attrs={ 'placeholder': _('john@email.com') } ) ) def __init__(self, *args, **kwargs): super().__init__(*args, **kwargs) self.helper = FormHelper() self.helper.form_show_labels = False self.helper.form_method = 'POST' self.helper.form_class = 'form-inline justify-content-center' self.helper.layout = Layout( Div( FieldWithButtons('email', Submit('Submit', 'submit', css_class='btn btn-outline primary')), Submit('submit', u'Submit', css_class='btn btn-success'), css_class='form-inline' ) ) #users/views.py class SubscribePageView(CreateView): form_class = CustomUserSubscribeForm success_url = reverse_lazy(‘subscribe’) template_name = ‘subscribe.html’ #users/urls.py from .views import SubscribePageView urlpatterns = [ path(‘subscribe’, SubscribePageView.as_view(), name=‘subscribe’), ] These views/html pages render and the … -
In Django, how can I get a count of records based on a subquery of a subquery?
A baseball player plays in a game if he makes one or more appearances in that game. So, to get a count of the number of games a player played in, you need to count the games that have an inning that have an appearance by that player. Here are my models: class Player(models.Model): ... class Game(models.Model): ... class Inning(models.Model): game = models.ForeignKey(Game, on_delete=models.CASCADE) class Appearance(models.Model): inning = models.ForeignKey(Inning, on_delete=models.CASCADE) player = models.ForeignKey(Player, on_delete=models.CASCADE) The SQL query to achieve what I want is: SELECT COUNT(*) FROM games_game WHERE id IN (SELECT game_id FROM innings_inning WHERE id IN (SELECT inning_id FROM appearances_appearance WHERE player_id = 1)) How could I do this in Django without using Raw SQL? Note that this is for a PlayerDetailView, so I just need it for a single Player object. -
Second app static files not being served in Django
I have two apps in my Django projecto: frontend and backend. The static files from the backend app are being served correctly. The folder hierarchy is backend - static - backend. I am now starting with the frontend app. The hierarchy is frontend - static - frontend. Yet, for this app, files are not being served. When trying to go to the file url I get a 'frontend\assets\vendor\nucleo\css\nucleo.css' could not be found. In my urls.py I have: urlpatterns = [ path('', views.index, name="frontend") ] + static(settings.STATIC_URL, document_root=settings.STATIC_ROOT) And in my settings.py I have: STATIC_ROOT = os.path.join(BASE_DIR, 'static') STATIC_URL = '/static/' -

Possible causes for error: Field cannot be both deferred and traversed using select_related at the same time?
I am trying to use graphene-django-optimizer to remove some of the unnecessary queries. It worked quite well until one certain field where I get this error message Field User.company cannot be both deferred and traversed using select_related at the same time. The only difference with this field is that it is models.OneToOne instead of models.ForeignKey. Why Django make this field deferred? Is it possible to disable field being deferred? -

How do I ensure that certain model instances are always present in django database?
My django-application requires a few model instances to always be present in the database to function properly. I currently create the model instances that I require in the Appconfig.ready(self) method for the corresponding app. This way the instances are always present on boot of the django-application. This works but not as well as I'd like, I have to be careful when deleting objects so that I do not delete the required objects. I would like the required model instances to be undeletable or preferably, be created whenever they are not present in the database. -
Send individual emails to multiple recipients without using BCC with the SparkPost API
Our Django app uses SparkPost as an email provider. A new feature we are implementing should allow users to create their own organizational emails and send them to whoever they wish. Now, these emails should be received as individual ones, not with multiple recipients ("to") so that users can't see each other's address. I have run a few tests with the SparkPost transmissions API. This is how you send an email: sp = SparkPost(API_KEY) response = sp.transmissions.send(recipients=emails, html=body, from_email=sender, subject=self.subject) Where emails is a list of string literals. In all test cases except one I did get individual emails with a single recipient just as I was after. But in one case the email had multiple "to" emails, and you could see each other's email address. I changed absolutely nothing in the code, this just happened. Is there any way I could do that other than sending an individual transmission for each recipient? I'm worried about performance if it comes to that: sp = SparkPost(API_KEY) for email in emails: sp.transmissions.send(recipients=email, html=body, from_email=sender, subject=self.subject) -

How to declare abstract class and methods for model implementation?
I wonder if there is a way in Django to create an abstract class where I can declare a method that should be implemented in a model. Normally, in Python, we declare abstract class like this: import abc class MyABC(metaclass=abc.ABCMeta): @abc.abstractmethod def do_something(self, value): raise NotImplementedError And then implement it like this: class MyClass(MyABC): def do_something(self, value): pass What I did with django is: import abc from django.db import models class MyClass(metaclass=abc.ABCMeta): @abc.abstractmethod def __str__(self): raise NotImplementedError class MyClass2(models.Model, MyClass): def __str__(self): pass But this gives me error: TypeError: metaclass conflict: the metaclass of a derived class must be a (non-strict) subclass of the metaclasses of all its bases I don't understand what I did wrong here. MyClass2 should inherit from MyClass and from models.Model. What I did wrong? Why this is wrong? What is the better way of declaring methods that should be implemented in models? -

How to change the Django-allauth default url patterns?
while using the django-allauth as the registeration system, the following codes work well: urls.py urlpatterns = [ path('accounts/', include('allauth.urls')), path('admin/', admin.site.urls), ... ] so, under this settings: when the user wants to signin, then go to 'example.com/accounts/login' when the user wants to signup, then go to 'example.com/accounts/singup' ... but now I want to change the urls to something like: when the user wants to signin, then go to 'example.com/staff/login' when the user wants to signup, then go to 'example.com/staff/singup' ... I just want to change 'accounts' in the urls to 'staff'. I've just tried to revise the urls.py to: urlpatterns = [ path('staff/', include('allauth.urls')), path('admin/', admin.site.urls), ] most of the registration funcitons worked well, except the email comfirmtion. I reveived the confirmation email and clicked on the comfirmation button, but then the redirect url will always be 'example.com/accounts/login', which raise a 404 error. I want to know how to fix this problem, I will: fix it, if this can be done in a few steps use the default settings, if this is complicated or will bring some risks. Versions: Python: 3.8.1 Django: 3.0.4 Django-allauth:0.41.0 I am a freshman on coding (and English), thank you very very much. -

Django filter by datetime month__gte is not working
