UPDATE 1: Code that gets me done with 1) (don’t forget tot pass CHOICES to the BooleanField in the model)

from main.models import TagCat
from django.contrib import admin
from django import forms

class MyTagCatAdminForm(forms.ModelForm):
    class Meta:
        model = TagCat
        widgets = {
            'by_admin': forms.RadioSelect
        }
        fields = '__all__' # required for Django 3.x
    
class TagCatAdmin(admin.ModelAdmin):
    form = MyTagCatAdminForm


admin.site.register(TagCat, TagCatAdmin)

The radio buttons appear ugly and displaced, but at least, they work

  1. I solved with following info in MyModel.py:
BYADMIN_CHOICES = (
    (1, "Yes"),
    (0, "No"),
)

class TagCat(models.Model):
    by_admin = models.BooleanField(choices=BYADMIN_CHOICES,default=1)

There is another way to do this that is, IMO much easier if you want every field of the same type to have the same widget. This is done by specifying a formfield_overrides to the ModelAdmin. For example:

from django.forms.widgets import Textarea

class MyModelAdmin(admin.ModelAdmin):
    formfield_overrides = {
        models.TextField: {'widget': Textarea},
    }

More in the docs: https://docs.djangoproject.com/en/dev/ref/contrib/admin/#django.contrib.admin.ModelAdmin.formfield_overrides

Here is a more dynamic extension of mgPePe’s response:

class MyAdminForm(forms.ModelForm):
    def __init__(self, *args, **kwargs):
        super(MyAdminForm, self).__init__(*args, **kwargs)

        self.fields['by_admin'].label = 'My new label'
        self.fields['by_admin'].widget = forms.RadioSelect()


    class Meta:
        model = TagCat

class MyAdmin(admin.ModelAdmin):
    fields = ['name', 'by_admin']
    form = MyAdminForm

This way you get full control over the fields.

You can also override this in the Admin class via the get_form() method.


class MyAdmin(admin.ModelAdmin):
    fields = ['name', 'by_admin']
    form = MyAdminForm

    def get_form(self, request, obj=None, change=False, **kwargs):
         form = super().get_form(request, obj, change, **kwargs)
         form.base_fields["by_admin"].label = 'My new label'
         form.base_fields["by_admin"].widget = forms.RadioSelect()
         return form
