How to make pre-selected checkbox in django?

Question

My form has CheckboxSelectMultiple widget receiving user's preferences.
I want to show a pre-checked preference to user.
I know there is one way to pre-check widget in the template.
But I want to know a way to pre-check in the view individually. How can I do that?

individually means controll individual checkbox in the CheckboxSelectMultiple widget — crazy_rudy, Mar 09 '13 at 18:32

Just pass the values you want to be checked to initial (see docs) when you instantiate the form:

MyForm(initial={
    'my_multi': ['a', 'b', 'c']
})

What's the meaning of 'my_multi'? – crazy_rudy Mar 09 '13 at 18:39
@user1924839 that's the name of your CheckboxSelectMultiple widget field, and a, b, c are the values you want checked. You didn't provide any sample code so I had to make them up. – mVChr Mar 09 '13 at 18:40

import django
from django import forms

class MyForm(forms.Form):
     option = forms.BooleanField(required=False, initial=True)

It renders so

<tr><th><label for="id_option">Option:</label></th><td><input checked="checked" type="checkbox" name="option" id="id_option" /></td></tr>
