Re: Drop Down Menu in Django Forms not working.

name is a ForeignKey field? If not, you shouldn't use queryset attribute there. Use choices instead.
If you want to render all available choices from db, you can get it like Model.objects.filter(...).values_list('name', flat=True)

Hi,

I am trying to have a drop down menu for a field in my form but seems like its not working as required.

This is my form: forms.py

eval_states = [
        ('ACTIVE',EvalState.objects.filter(name='ACTIVE')),
        ('INACTIVE',EvalState.objects.filter(name='INACTIVE')),
        ('DELETE',EvalState.objects.filter(name='DELETE')),
        ]

class EvalForm(forms.ModelForm):
    def __init__(self, *args, **kwargs):
        super(EvalForm, self).__init__(*args, **kwargs)
        self.fields['name'].queryset = EvalState.objects.filter(
                Q(name = 'ACTIVE') | Q(name = 'INACTIVE') | Q(name = 'DELETE'))

    class Meta:
        model = EvalState
        fields = ('name',)

my html : abc.html

    <form name="eval_form" method="post" action="#">{% csrf_token %}
        <table class="pairs">
            <tr>
                <th>Eval State:</th>
                <td>
                    {{ eval_form.name }}
                    <input type="submit" value="Save">
                </td>
            </tr>
        </table>
    </form>

view.py
    eval_form = None
    eval_form = atlas_forms.EvalForm(request.POST, EvalState)
    if eval_form.is_valid():
        print eval_form.errors
        eval_form.save()
    else:
        print eval_form.errors


What am i missing?
Basically requirement is that, i would need a drop down in the HTML and whenever the Value is set and saved, I want it to be updated in the DB.
But i am not able to get through the first step of getting the options in the HTML.

Any Help on this would be great.

Thanks
cheers
Arun.
