Question

I wanted to show multiple choices to admin so that at one time he can select more then one from these choices. I can do this using check boxes fields.I have tried this but instead of showing check boxes it shows me drop down list of choices.

Here is my code.

models.py

class segmentation_Rules(models.Model):
        Segmentation_Rules_CHOICES = (
                        (1, 'At least one order'),
                        (2, 'Have reward points'),
                        )
        Rules       =models.CharField(max_length=100, blank=True,verbose_name="Select rules for customer segmentation",choices=Segmentation_Rules_CHOICES) 

forms.py

class Segmentation_Form(ModelForm):
        Rules = forms.MultipleChoiceField( widget=forms.CheckboxSelectMultiple)

admin.py

class MyAdmin(admin.ModelAdmin):
    form = Segmentation_Form

So please show me some way so that admin can select multiple fields from choices.

EDIT:

And if I remove the choices from models and define them into forms then there is just a text field shown to admin with no choices.

Segmentation_Rules_CHOICES = (
            (1, 'At least one order'),
            (2, 'Have reward points'),
            )

class Segmentation_Form(ModelForm):
        Rules = forms.MultipleChoiceField(choices=Segmentation_Rules_CHOICES, widget=forms.CheckboxSelectMultiple())

        class Meta:
            model=segmentation_Rules

You need to remove the choices argument from the model field definition in models.py and add choices field to the Rules form field in forms.py. Like so:

models.py

class segmentation_Rules(models.Model):
    Segmentation_Rules_CHOICES = (
        (1, 'At least one order'),
        (2, 'Have reward points'),
    )
    Rules = models.CharField(max_length=100, blank=True, verbose_name="Select rules for customer segmentation") 

forms.py

class Segmentation_Form(ModelForm):
    Rules = forms.MultipleChoiceField(widget=forms.CheckboxSelectMultiple(), choices=models.segmentation_Rules.Segmentation_Rules_CHOICES)
