I need to forrward this data as python list to django, not as string. How to create list, just to input data separated with commas?

class CreateForm(forms.Form):
    list = forms.CharField(label='Input names (separate with commas): ')

You can define your own field to make it a comma separated field. This then looks like:

# app_name/fields.py

class CommaSeparatedField(forms.CharField):

    def to_python(self, value):
        if value in self.empty_values:
            return self.empty_value
        value = str(value).split(',')
        if self.strip:
            value = [s.strip() for s in value]
        return value

    def prepare_value(self, value):
        if value is None:
            return None
        return ', '.join([str(s) for s in value])

and then use it in the form with:

# app_name/forms.py

from app_name.fields import CommaSeparatedField

class CreateForm(forms.Form):
    list = CommaSeparatedField(label='Input names (separate with commas): ')

Django will then return a list of strings in the form.cleaned_data in case the form is valid.
