Can I override default CharField to ChoiceFoeld in a ModelForm?
I have a (horrible) database table that will be imported from a huge spreadsheet. The data in the fields is for human consumption and is full of "special cases" so its all stored as text. Going forwards, I'd like to impose a bit of discipline on what users are allowed to put into some of the fields. It's easy enough with custom form validators in most cases. However, there are a couple of fields for which the human interface ought to be a ChoiceField. Can I override the default form field type (CharField)? (To clarify, the model field is not and cannot be constrained by choices, because the historical data must be stored. I only want to constrain future additions to the table through the create view). class HorribleTable( models.Model): ... foo = models.CharField( max_length=16, blank=True, ... ) ... class AddHorribleTableEntryForm( models.Model) class Meta: model = HorribleTable fields = '__all__' # or a list if it helps FOO_CHOICES = (('square', 'Square'), ('rect', 'Rectangular'), ('circle', 'Circular') ) ...? -

Conditional query in django [closed]
Am worried that it may cause any problem, as am using conditional querying paramters. Here is my query: data = Project.objects.filter(user=user if user.role == 1 else user.staff_to_id) In this, staff_to_idis just a self reference to a user to represents that this is a staff. So if Role == 1 then Projects will be fetched using "user" and when Role == 2 or something else it will Project will be fetched using "user.staff_to_id" Is this a bad practice ? -

Disabling and reassigning a new django token
I am planning to use "RestFrame TokenAuthentication" for django API requests. I want to give the Bearer Token to my client for accessing the API. The token needs to be disabled based on payment module. On a succesful payment, i needs to create a new token programatically and give it to the client. Is it possible to deactivate and renew with a new token when necessary ? Is it the best practice to use "RestFrame TokenAuthentication" for such a scenario ? -
Django: Create a Model from parsing a different model's field
I have a model A with several fields. One of the fields ("results") is a a dict-like string in my database (which is hardly readable for a human being). Can I create a separate Model that would basically parse that "results" field into its own fields, so I can have a separate table with fields corresponding to the keys and values from my "results" field from model A? Final goal is to make a Results table that shows all the information in a pretty and easy-to-read manner. class ModelA(models.Model): language = models.CharField(max_length=30) date = models.DateTimeField() results = models.CharField(max_length=255) This is how "results" field looks in my database (I cannot change this format): OrderedDict([('Name', 'Bob'), ('Phone', '1234567890'), ('born', '01.01.1990')]) I want to create something like this: class Results(models.Model): name = model.Charfield(max_length=100) phone= model.IntegerField() born = model.DateTimeField() What is the best way to do this? How do I take the info from the "results" field from ModelA and "put" it into the Results model? -

Django-admin: show multi select field for JSONField
I have a model with a field channel (JSONField). I'm strong an array of string in db with channel. By default, a JSONField is shown as a textarea in django-admin. My goal is to somehow make channel a multi-select field that later converts to like this ["APP", "WEB"]. models.py @dataclass class ChannelTypes: WEB: str = 'WEB' APP: str = 'APP' class DiscountRule(models.Model): ... channel = models.JSONField(null=False, blank=False, default=list(astuple(ChannelTypes()))) My Approach: In forms.py, add custom fields (boolean) that only show up in admin form and are not stored in db. Something like this: class RuleAdminForm(forms.ModelForm): WEB = forms.BooleanField(required=False) APP = forms.BooleanField(required=False) Similarly, admin.py will populate the custom fields like this: def get_form(self, request, obj=None, *args, **kwargs): form = super(BaseDiscountRuleAdmin, self).get_form(request, *args, **kwargs) for i in obj.channel: form.base_fields[i].initial = True return form But this causes a problem that the custom field value persists after updating 1-2 times due to using base_fields[field_name].initial.
