Django: BooleanField not displayed with the 'default' CheckBoxInput but with Select?

Question

I've just updated my one field of a model from IntergerField to BooleanField in order to have Checkbox in my admin form but it doesn't...

Instead, It display a select list with 3 option (Unknown, Yes, No)

As mentionned in the Django admin documentation, CheckBoxInput is the default widget so it shloudl works

I try to 'force' CheckBoxInput defining a widget forms.CheckBoxInput but it doesn't works neither...

I need this field to be editable. i verifiy that this not this option that prevent default widget but it isn't.

models.py

class Profile(SafeDeleteModel):
    _safedelete_policy = SOFT_DELETE_CASCADE
    pro_ide = models.AutoField(primary_key = True)
    user = models.OneToOneField(User, on_delete = models.CASCADE)
    site = models.ForeignKey(Site, on_delete = models.CASCADE)
    ...
    pro_mai = models.BooleanField("Send user login/password? (y/n)",default=0, null=True, blank=True)
    ...

admin.py

class ProfileFormAdmin(forms.ModelForm):

    FONCTIONS = Thesaurus.options_list(5,'fr')
    pro_mai = forms.BooleanField(label="Envoyer le mot de passe ? (Oui/Non)",required=False)
    pro_fon = forms.ChoiceField(label="Fonction", widget = forms.Select, choices = FONCTIONS) 

def send_login_password(modeladmin, request, queryset):
    queryset.update(
        pro_mai = 1,
    )
send_login_password.short_description = 'Envoyer login et mot de passe à l\'utilisateur'

class ProfileAdmin(SimpleHistoryAdmin):

    list_display = ('name','contact','pro_mai','fonction',)
    list_editable = ('pro_mai',)
    exclude = ('pro_con','pro_lis_ran', 'pro_lis_rea', 'pro_lis_unb','pro_tel')
    search_fields = ['name']
    actions = [send_login_password]
    form = ProfileFormAdmin

problem come from sqlite field format that was NULL and edited as NullBoleanField instaed as BooleanField... resolved adding Not null constraint in models — SLATER

In your boolean field here:

pro_mai = models.BooleanField("Send user login/password? (y/n)",default=0, null=True, blank=True)

Remove the null value. When you make null=True in your boolean field, it will bring up the select widget instead of the checkbox widget.

You can find more information about it on Django's BooleanField Model field reference.
