Django - Adding custom class to label_tag
I am trying to figure out a way to add a class to my tag on my form. I want to accomplish this without something like crispyforms and if possible not having to edit the html. Based on my knowledge and googling I have spent a few hours trying to figure this out but I cannot haha. I basically just want to output a class in the label element like so: <label class='text-muted' for="id_street_address">Street Address:</label> My model is as follows: class CheckoutForm(forms.Form): street_address = forms.CharField(widget=forms.TextInput( attrs={ 'class': 'form-control' } )) apartment = forms.CharField(required=False, widget=forms.TextInput( attrs={ 'class': 'form-control' } )) country = CountryField(blank_label='(select country)') zip_code = forms.CharField(widget=forms.TextInput( attrs={ 'class': 'form-control' } )) same_billing_address = forms.BooleanField(widget=forms.CheckboxInput()) save_info = forms.BooleanField(widget=forms.CheckboxInput()) payment_option = forms.BooleanField(widget=forms.RadioSelect()) def __init__(self, *args, **kwargs): super().__init__(*args, **kwargs) self.fields['street_address'].label = 'Street Address' self.fields['apartment'].label = 'Address 2 (optional)' self.fields['zip_code'].label = 'Zip Code' I render my form in the template like this: <form> {% csrf_token %} {% for field in form %} <div class="form-group px-3 my-3"> {{ field.label_tag }} {{ field }} {{ field.help_text }} {{ field.errors }} </div> {% endfor %} </form> Is it possible to do this? Any help is greatly appreciated -
stop Django admin actions from showing project wide
I've got a project with quite a few admin-actions. Currently I'm registering them like so: @admin.action(description='Some admin action description') def do_something_action(self, request, queryset): pass Some of these are being added to the admin-class of another app so I cannot simply add the function directly on the class where they are needed. The problem is that these actions are shown project-wide, on every admin-screen. How can I stop this behaviour, and manually set them where they are wanted? If it matters, it's Django3.2. -

Is it possible to get the value of a Factory boy Faker object for use in another field while making a DjangoModelFactory
I am trying to use factory boy to create a model instance for events, but I am needing to see if I can access the result of a Faker declaration in another field. In the code below, I want to access the start_time field in the end_time field so I can create a datetime that is 1 hour from the start_time. It complains that start_time is a faker object, and not a datetime object.

Django update_or_create throws an error, but works properly from shell
Say I have two models which are bound by OneToOne relation. class Person(models.Model): ... class Pear(models.Model): consumer = models.OneToOneField( Person, on_delete=models.CASCADE ) color = models.CharField() ... Person ModelSerializer nests Pear ModelSerializer. Person ModelSerializer also has update method which calls update_or_create for Pear. It looks like this. class PearSerializer(serializers.ModelSerializer): class Meta: model = Pear fields = '__all__' class PersonSerializer(serializers.ModelSerializer): pear = PearSerializer(required=False) class Meta: model = Person fields = '__all__' def update(self, instance, validated_data): pear_data = validated_data.pop('pear') ... if pear_data is not None: obj, created = Pear.objects.update_or_create( consumer=pear_data.get('consumer'), defaults={'color': pear_data.get('color')} ) ... So it throws an error saying that the consumer field value should be unique. At the same time update_or_create with the same parameters and absolutely same data works perfectly if called through shell. What am I missing? Thanks. -

MySQL replication for Graphene Django
I'm using Graphene as a GraphQL server in Django. I set up a MySQL replica in Django. My setting is pretty simple. Read requests -> Replica. Write requests -> Source Mutations works in the next way: They modify data and then return modified/new data. Graphene modifies data in Source and immediately selecting them from Replica. The problem is that updated data is not immediately appearing in Replica DB (because of Replication delay). As result, some mutations simply do not work. I have a solution - specifying the Django database in every mutation. Didn't tried it yet. But the project is huge, and this requires a lot of changes in the codebase. I'm looking for simpler solutions. DATABASES = { 'default': { 'ENGINE': 'django.db.backends.mysql', 'NAME': 'db_name', 'USER': 'root', 'HOST': MYSQL_HOST, 'PORT': '3306', }, 'read_replica': { 'ENGINE': 'django.db.backends.mysql', 'NAME': 'db_name_replica', 'USER': 'root', 'HOST': MYSQL_HOST_REPLICA, 'PORT': '3306', } } DATABASE_ROUTERS = ['app.db_router.DatabaseRouter'] class DatabaseRouter: def db_for_read(self, model, **hints): return 'read_replica' def db_for_write(self, model, **hints): return 'default' def allow_relation(self, obj1, obj2, **hints): return True def allow_migrate(self, db, app_label, model_name=None, **hints): return True -
Django Allauth - Facebook Login does not produce email
I have issues with the django-allauth facebook login. I have configured the facebook login successfully and I am able to send a request to facebook and get the user's information back to my console to create the user to login. I have met an unusual issue in this process however. When I print the results I obtain from the facebook API to inspect the results, I manage to get a dictionary with "first_name", "last_name" and "name" populated with the facebook user's information but the field "email" and "username" carry a value of None. This is problematic because instead of being able to move forward with the account creation, the user is shown an allauth default html page with a form to enter the email/username. I would like to skip this page altogether and I could if I had the email in the first place. The dictionary that I get is the "data" coming out of allauth/socialaccount/adapter.py function populate_user(populate_user(self, request, sociallogin, data). Maybe I should have the email at the different step? My settings are set up as such: LOGIN_URL = 'login' LOGIN_REDIRECT_URL = '/' LOGOUT_URL = 'logout' LOGOUT_REDIRECT_URL = 'login' SOCIAL_AUTH_RAISE_EXCEPTIONS = False ACCOUNT_EMAIL_REQUIRED = True ACCOUNT_USERNAME_REQURIED = True ACCOUNT_AUTHENTICATION_METHOD … -

Filtering on a Window function in Django
I have the following model: class Foobar(models.Model): foo = models.IntegerField() And I figured out how to calculate the delta of consecutive foo fields by using window functions: qs = Foobar.objects \ .annotate( delta=F('foo') - Window(Lag('foo'), partition_by=F('variant'), order_by=F('timestamp').asc()) ) Now I only want the records from this where delta is negative: qs.filter(delta__lte=0) But as you might expect, this gives an error: django.db.utils.NotSupportedError: Window is disallowed in the filter clause.

Why do errors differ when I interchange the order of the members of url patterns
Note: I'm not requesting for a help to fix the errors, but to ask the reason why they differ by interchanging the order of url patterns.

Accessing submitted form data in separate Django view
I have looked around on SO for a solution to what seems to be a very simple question, but I've not been able to find anything matching. I'm making a simple recipe app in Django. I have made 3 models, one for recipe information like title etc, one foreignkey model for ingredients, and one foreignkey model for methods. From these I have made a model form for the recipe information and two formsets for the ingredients and methods. Everything is working fine on the form page and data is submitting and viewable in Django admin. Please see below my Django view. def make_recipe(request): if request.method == "GET": form = RecipeForm() iformset = IngredientFormSet() mformset = MethodFormSet() return render(request, 'recipes/create_recipe.html', { 'form':form, 'iformset':iformset, 'mformset':mformset,}) elif request.method == "POST": form = RecipeForm(request.POST) if form.is_valid(): recipe_card = form.save() iformset = IngredientFormSet(request.POST, instance = recipe_card) if iformset.is_valid(): ingredients = iformset.save() mformset = MethodFormSet(request.POST, instance = recipe_card) if mformset.is_valid(): methods = mformset.save() if form.is_valid() and iformset.is_valid() and mformset.is_valid(): return redirect('recipe_submitted') And my template: {% extends 'recipes/base.html' %} {% block content %} <form action="." method="post"> {% csrf_token %} <h1>Recipe Information</h1> {% if error_message %} <p><strong>{{ error_message }}</strong></p> {% endif %} {{ form.as_p }} <hr> <h2>Ingredients</h2> {{ … -
Django expects wrong format when validating modelform datefield
I have a page where the user inputs some dates in the dd/mm/yyyy format. In my settings file I have this: DATE_INPUT_FORMATS = ('%d/%m/%Y','%Y/%m/%d', '%Y-%m-%d',) I use the django bootstrap4 datetime picker plus The field renders as such: (i apologize about the screenshot, i couldnt copy the html without it being escaped and it looked extra-messy) The problem The problem is that when i input dates in dd/mm/yyyy format, it uses the american format (mm/dd/yyyy) to validate them. So if i enter 27/12/2021 it will try to save [day 12, month 27, year 2021] and fail the validation. Preventing the formset from being saved. What i don't understand is where in hell does django get the idea that it should use the american format to validate dates when I have set three separate DATE_INPUT_FORMATS and none of them are in the american format? Here an image showing that on the page the date is collected in the right format And the response : [{'start_date': ['Enter a valid date.'], 'end_date': ['Enter a valid date.']}] Forms this is where i am now: class EducationForm(forms.ModelForm): # def clean_start_date(self): # print(self.cleaned_data['start_date']) # return datetime.strptime((self.cleaned_data['start_date']), '%Y-%m-%d') # def clean_end_date(self): # return datetime.strptime((self.cleaned_data['end_date']), '%Y-%m-%d') class Meta: … -

Django Send Mail in IIS 10
My company requires production/development in IIS. I've developed an app that sends email notifications on form submittal. Emails are sent with a google mail account. It works great when I run the app on the django development server (manage.py runserver). When I run the app on IIS server, I am unable to send emails. I get the SMTPSenderRefused 530, b'5.7.0 Authentication Required error. I have searched hi and low for documentation that would address this problem, with no luck. Since django is sending the email through its django.core.mail.backends.smtp.EmailBackend, I wouldn't think I need to do any settings in IIS (i.e. web.config file etc)? Any suggestions of where to read up would be great. Thank you. -
