Data is shown before form submission in Django 4.1
community! My goal is to create an app, which takes some user input, does machine-learning stuff and shows the results. I want to know whether the result was correct for each prediction. That's why I'm trying to implement a feedback system, where a user could mark the answer as "correct" or "incorrect" if one wants to do so. To be exact, I have two buttons: "the prediction looks like true" and "the prediction was incorrect". After clicking on one of these buttons I have a pop-up dialog shown with 3 checkboxes, where a user can provide additional information (it is not required). forms.py with these checkboxes looks like this: from django import forms class checkboxForm(forms.Form): is_winner_reason_true = forms.BooleanField(required=False, label="The first place in importance coincides with reality", label_suffix='') is_top5_reason_true = forms.BooleanField(required=False, label="Top 5 includes friends with high importance", label_suffix='') is_other_reason_true = forms.BooleanField(required=False, label="Other", label_suffix='') class checkboxFormFalsePred(forms.Form): is_winner_reason_false = forms.BooleanField(required=False, label="The other person should come first in importance", label_suffix='') is_top5_reason_false = forms.BooleanField(required=False, label="Top 5 includes friends with low importance", label_suffix='') is_other_reason_false = forms.BooleanField(required=False, label="Other", label_suffix='') I want to get data from clicking on one of two buttons (the value will be either True or False) and then, if a user decided to … -

How to reuse properties from table with django?
oke. I have one table. like: class AnimalGroup(models.Model): name = models.CharField(max_length=50, unique=True) description = models.TextField(max_length=1000, blank=True) images = models.ImageField(upload_to="photos/groups") class Meta: verbose_name = "animalgroup" verbose_name_plural = "animalgroups" def __str__(self): return self.group_name And this are animal groups. Like: mammals fish reptils But then I hava a subgroup where a user can enter the same properties as by AnimalGroup. And the AnimalGroup can have multiple subgroups. Like: mammals: cats, dogs, cattles. And then you have the animal it self: cats: siamese cat, ragdoll, etc. My question is: how can I resuse this properties for the three objects? So AnimalGroup subgroup animal So that a user can enter in the admin panel of django: mammals fish reptils and then can enter cats and choose from dropdown mammals. Because all the objects: AnimalGroup subgroup animal have in common the fields: name description images -

How can I make the selection value in the model form Django based on the value selected above?
Good day! I have a model table in order to add data to this model. [Citizen_2] At me in the field the country is selected by the user. The form then records the city based on the selected country value. You need to save them in the [Citizen_2] table model so that the city corresponds to its country in the corresponding fields. I've been thinking about how to do this for a week now. I would be very grateful for any hints. I would like users to enter their country of residence first, it's like a simple one-field form. And then a form of two fields - where it is proposed to select the country of residence from the value already entered in the (name_country) field. For example, I have users added three countries there. Then they add the cities - for those respective countries. In the drop-down form field, select a country and write down your city there. And send the data to the model table. It is necessary that the data be saved in such a way that the city corresponds to the country to which the user wrote it down in the form. This is then used … -
