How can I create a Django model for a form in which users can choose to add more fields?

Question

Is this the correct way to write out all the fields in models.py and forms.py ? I am sure there must be a cleaner way to do this rather than individually listing out all fields and differentiating them with a number at the end.

I have looked into Django FormSets but I am not sure how I would use that with Django WizardForms.

Thank you

Answer 1

you have ModelForm in django

class ProfileFour(form.ModelForm)
    class Meta:
       model = Profile
       fields = '__all__'  # you wand all field
       # or 
       fields = ['education_school', 'education_degree' ..] # name the field you want

doc django's really good, read it.

https://docs.djangoproject.com/fr/3.0/topics/forms/modelforms/

edit : for completed the answer of @Countour-Integral

class Profil(models.Model)
   username = models.charField()
   ...

class Education(models.Model)
    profil = models.ForeignKey(Profil)
    school = models.CharField()
    degree = models.IntegerField()
    field = models.CharField()
    start = models.DateField()
    end = models.DateField()
    grade = models.CharField()
    description = models.textField()

Answer 2

You're looking at this the wrong way. Firstly, your model should be updated to reflect your use case. If you don't know the fields ahead of time, you can use a JSONField contained in an ArrayField eg

education = ArrayField(models.JSONField(default=dict), size=10, default=list)

Now that we've got that out of the way, the better way to do what you want is to have Education as a model, and then the Profile model would have a foreign key to Education . ie

class Education(models.Model):
  school = models.CharField(max_length=50)
  degree = models.CharField(max_length=50)
  ...rest of fields

Then your Profile model would have: education = models.ForeignKey(Education, related_name="profile")

To get a varying number of education forms, you should take advantage of modelformset . Create your EducationForm as a normal modelForm instance, then:

EducationFormSet = modelformset_factory(Education, form=EducationForm, max_num=10, extra=1)

Answer 3

Instead of writting the same code 5 times you could just use a ManyToMany field.

class Profile(models.Model):
    education_school            = models.ManyToManyField( blank=True)
    education_degree            = models.ManyToManyField( blank=True)
    education_field             = models.ManyToManyField( blank=True)
    education_start             = models.ManyToManyField( blank=True)
    education_end               = models.ManyToManyField( blank=True)
    education_grade             = models.ManyToManyField( blank=True)
    education_description       = models.ManyToManyField( blank=True)

• and then you could define each field seperately

class education_school(models.Model):
    education_school = models.CharField(max_length=500, null=True, blank=True)

and so on with the other fields
