django forms queryset doudt

when were i fetch a data from model it displays the all data from table.

support : i have table xyz

class xyzform(forms.Form):
   test=xyz.objects.filter(m='name').vlaues('doj')

in html

{{form}}

it won't output nothing,only submit button is displayed

if i remove vlaues('doj'),it displays all the data .

1.My question is ,how to display only specific filed in the form ?

2.Another question how to fetch remote.meta.get('remote_user') in to query set filter in the form ?

for example :

 开发者_运维百科 name =remote.meta.get('remote_user')

You need to read the django forms docs from the beginning to understand how to use the forms framework.
http://docs.djangoproject.com/en/dev/topics/forms/

Following the examples will illustrate "how it works" (5 minutes).

Forms look more like this:

class XYZForm(forms.Form):
    field = forms.CharField() 
    # forms only know how to display themselves with relevant 
    # forms.FOOField definitions.

As for passing request variables into the form, you'd have to override __init__ so you can pass extra arguments into the form constructor from your view.

class XYZForm(forms.Form):
    field = forms.CharField()

    def __init__(self, remote_user, *args, **kwargs):
        super(XYZForm, self).__init__(*args, **kwargs)
        # do something with remote_user

# view
form = XYZForm(remote_user = remote.meta.get('remote_user'))
