How to customize the admin form for a custom image model in Wagtail CMS?
I need to add a string based unique ID to Wagtail’s image model. These IDs are a relatively short combination of letters, numbers and punctuation, e.g. "AS.M-1.001". So I am using a custom image model with Django’s standard CharField for that with the argument unique=True. But the editing form unfortunately does not check if the ID is unique. So I can use the same ID for multiple images. This check for uniqueness does work in any other standard form in Wagtail, e.g. the Page model. But not for the image model. from django.db import models from wagtail.images.models import Image, AbstractImage class CustomImage(AbstractImage): custom_id = models.CharField(max_length=32, unique=True, null=True, blank=True) admin_form_fields = ( 'custom_id', ) + Image.admin_form_fields My approach would be to override the editing form with a custom one to display more warnings and errors, like you can do with base_form_class for Wagtail’s Page model etc., as documented here. I tried both wagtail.admin.forms.WagtailAdminModelForm as well as wagtail.images.forms.BaseImageForm. from wagtail.images.forms import BaseImageForm from wagtail.admin.forms import WagtailAdminModelForm class CustomImageForm(WagtailAdminModelForm): # add more logic here pass class CustomImage(ArtButlerIDMixin, AbstractImage): ... base_form_class = CustomImageForm Both lead to the same exception: raise AppRegistryNotReady("Models aren't loaded yet.") So a tried to resort the apps in my settings … -

Using a GIN index in Django which was created in postgreSQL
I have created a model in Django. class MyModel(models.Model): features = TextField(blank=True, default='') There are several possible ways to store the data in the feature field. Some examples below. feature1;feature2 feature1, feature2 feature1,feature2 And so on. I created a GIN index for that field. That's postgreSQL code I used inside migrations.RunSQL. CREATE INDEX features_search_idx ON "mymodel" USING gin (regexp_split_to_array("mymodel"."features", E'[,;\\s]+')); The migration worked and I managed to find that index using, for example, \di+ mymodel_features_search_idx. Now I would like to use that created index to filter my queryset. I thought something like the code below would work MyModel.objects.annotate(F('features_search_idx')).filter(features_search_idx__in=['Feature1', 'Feature2', 'Feature3'].count() Unfortunately an error occurred django.core.exceptions.FieldError: Cannot resolve keyword 'feature_search_idx' into field.. How can I use my created index? -

Django OTP TOTP - how to display QR code in template
I have successfully implemented two-factor-auth package to my web app however I would like to display QR code to a template when a user is logged in but am unable to do so as it stands. This package uses wizard forms and when a user is prompted to setup two factor the QR code is displayed during setup for them to scan on their chosen device but not sure how to use the QR code for later use in another template. I found the follwing piece of code from the wizard template which I tried to use but says page not found: <div class="d-flex justify-content-center"> <p><img src="{{ QR_URL }}" alt="QR Code" /></p> </div> Page not found error Using the URLconf defined in wfi_workflow.urls, Django tried these URL patterns, in this order: admin/ account/login/ [name='login'] account/two_factor/setup/ [name='setup'] account/two_factor/qrcode/ [name='qr'] The current path, account/two_factor/qrcode/, matched the last one. But I can view the QR code for users via Admin panel under: Otp_Totp TOTP devices Click on user and QRCode link is at the bottom of page Anyone know how to go about displaying the QR code only in another template? If more info is required do let me know. Thanks -
Django User Manager Not Checking Model Validators
I'm using a custom django user model. I have created everything and all seems perfect until I try to call the create_user from a registration page on the template. It is creating the user without taking the validators I have placed in the models into consideration. The validators are working just fine until I try to use the create_user action. def validate_reg(value): try: x = SignUpAccess.objects.get(reg_key=value) if x.is_used == True: raise ValidationError( message='Your validation number is used already', ) except SignUpAccess.DoesNotExist: raise ValidationError( message='Your validation number does not exist', ) class User(AbstractUser): username = None email = models.EmailField( unique=True, max_length=75, # db_index=True, primary_key=True, verbose_name='email address' ) reg_number = models.CharField( max_length=12, unique=True, null=True, validators=[validate_reg] ) first_name = models.CharField(max_length=20) last_name = models.CharField(max_length=20) is_active = models.BooleanField(default=True) is_staff = models.BooleanField(default=False) is_superuser = models.BooleanField(default=False) date_joined = models.DateTimeField(default=timezone.now) REQUIRED_FIELDS = [] USERNAME_FIELD = 'email' objects = UserManager() As seen above I have added a validator in the registration number to make sure only those with a valid registration number can create an account on the site. This works perfectly when I try to create a user from admin (which is really pointless). As with custom user models, I have a user manager class UserManager(BaseUserManager): def create_user(self, … -

JavaScript POST non-API request with repeated keys in payload
Javascript. POST request. It is not an API request (axios or fetch), but the old classical request. I need a payload like ...&_selected_action=5&_selected_action=10. So I think I cannot use a form submitting technique here. With a single occurence ...&_selected_action=5 I am able to do it, everything works well. For the repeated value I can create the string by hand or by URLSearchParams().toString() but I am not able to send it. Any idea? More details. I need create this request in Django+Vue application which partially replaces the old school Django Admin. The ListView is replaced using Vue and now I want to reuse the actions where Django Admin uses Post request formatted as above. So with single selected row in list I am able to do it, but with 2+ selected rows I cannot find a good way how to do it. -

Django rest framework - serializer for dictionary structured payload
I'm trying to create a Serializer for a payload that looks something like this - { "2fd08845-9b21-4972-87ed-2e7fd03448c5": { "operation": "Create", "operationId": "356f6501-a117-4c8d-98ce-dcb4344d481b", "user": "superuser", "immediate": "true" }, "fe6d0c85-0021-431e-9955-e8e1b1ebc414": { "operation": "Create", "operationId": "adcedb2f-c751-441f-8108-2c29667ea9cf", "user": "employee", "immediate": "false" } } I thought of using DictField, but my problem is that there isn't a field name. it's only a dictionary of keys and values. I tried something like: class UserOperationSerializer(serializers.Serializer): operation = serializers.ChoiceField(choices=["Create", "Delete"]) operationId = serializers.UUIDField() user = serializers.CharField() immediate = serializers.BooleanField() class UserOperationsSerializer(serializers.Serializer): test = serializers.DictField(child=RelationshipAuthorizeObjectSerializer()) But again, there isn't a 'test' field. -

Django: Renaming Models, M2M Table not renamed
TLDR: Models moved to a new app. After migrating M2M relation refers to table that does not exist. Previous M2M table was not renamed. Django Version: 3.2.3 Scenario: I am refactoring a Django application. In this process I have moved some models to a new app. To do so, I renamed the tables as described by Haki Benita, using SeparateDatabaseAndState. One of the models Studentsin the new app has a field with Many2Many relationship to another model Teachers (which I also moved to the new app). oldapp/migrations/000X_auto_XXX.py operations = [ ... migrations.SeparateDatabaseAndState( state_operations=[ migrations.DeleteModel( name='Students', ) ], database_operations=[ migrations.AlterModelTable( name='Students', table='newapp_students' ) ] ), migrations.SeparateDatabaseAndState( state_operations=[ migrations.DeleteModel( name='Teachers', ) ], database_operations=[ migrations.AlterModelTable( name='Teachers', table='newapp_Teachers' ) ] ), ... ] newapp/migrations/0001_initial.py operations = [ ... migrations.SeparateDatabaseAndState( state_operations=[ migrations.CreateModel( name='Teacher', fields=[...], options={...}, ) ], database_operations=[] ), migrations.SeparateDatabaseAndState( state_operations=[ migrations.CreateModel( name='Students', fields=[ ...

However, the model in the new app refers to a table in the new app (newapp_students_teachers) that does not exist. I did some … -
