How to run django tests in a pre-commit hook
I'm stuck on how to simply run my django tests in a pre-commit hook. I will eventually put them in the push stage, but I'm just trying to get them to run first. It's trying to loop over my tests, but the tests object is a NoneType object. Works fine outside of this hook. I'm sure this is obvious to someone. Thanks. This is my test hook. repo: local hooks: - id: tests name: run tests always_run: true entry: python manage.py test language: system types: [python] -
User Authentication With Django Restframework and google
so i'm new to django and django rest api and i'm struggling with drf authentication. I'm trying to build an api with DRF that enables my users sign up with google. I've spent the last few days doing research but i've found more information on how to implement this in django as an app(which i have successfully done) but i need helping with implementing it in DRF. So far i have tried to use django oauth tool kit and socialoauth but i keep failing because most of the tutorials are not beginner friendly and make a lot of assumptions. I then spend hours trying to find out what they meant. This api will be used by an ios app and a webapp I would really appreciate any help. -
How to map the two heroku connect columns _hc_err and _hc_lastop in django ORM?
I've been trying to map the two columns which automatically gets created by heroku connect i.e. "_hc_err" and "_hc_lastop". These contain the value of the status of syncing to salesforce. Now, when I try to map them in django ORM, considering it to be a text field, it throws an error- (models.E008) Field '{variable_in_model_class}' has column name '_hc_err' that is used by another field. HINT: Specify a 'db_column' for the field. If it means that it is a foreign key rather than a text field, then which table should I relate it to? And what should I specify for Lookup i.e. "sf_field_name", "to" and "to_field" which we use for hc_models? I want these fields to check if the record has been successfully synced to salesforce or not. I know that we can use TriggerLogs but they are there for 30 days max in the archive. I want to check the status later as well. -
Access django rest framework CreateApiView response object with jQuery
I want to create an instance of User with ajax call. My view is a heir of CreateApiView and looks like this: class ManagerSignUp(CreateAPIView): serializer_class = ManagerSignUpSerializer permission_classes = [permissions.AllowAny] def perform_create(self, serializer): property_id = check_identifier(uuid.uuid4()) Hotel.objects.create( name=serializer.validated_data.get('works_for'), property_id=property_id ) serializer.save( title=TitleChoice.manager, property_id=property_id ) The jQuery function looks like following: $('#submitform').click(function () { var form = $(this) $.ajax({ url: form.attr('action'), data: form.serialize(), type: 'post', dataType: 'json', success: function (data) { console.log(data) } }) }) It creates User but as you could've guessed it doesn't log anything to the console, but renders standard DRF page. How can I access the data from serializer and prevent rendering the common DRF HTML? -

ModelMultipleChoiceField initial values
I'm struggling to include the right initial values for a ModelMultipleChoiceField (as checkbox widget). I generate the required initial selection in the view and pass it to the form as 'data' via **kwargs. Using print(...)

How can I link an input to an object's attribute and update that attribute as you click on it?
Given these model, view, and template files: models.py class Item(models.Model): class Included(models.IntegerChoices): YES = 1 NO = 0 included = models.IntegerField(choices=Included.choices, default=Included.YES) name = models.CharField() views.py def index(request): items = Item.objects.all() context = { 'items':item } return render(request, template.html, context( template.html {% for item in items %} {{ item.name }} <input type="checkbox"> {% endfor %} How can I do it such that the checkbox reflects if the Item it's with is included or not? How can I change if it's included or not by just ticking the checkbox? In general, how can I link an input to an object's attribute and update that attribute as you click on it? I don't think it would be feasible to use forms here, as it only changes a field. Plus if it's possible, do it realtime. Forms won't update a page unless you refresh it afaik, any ideas?
