UnboundLocalError: local variable referenced before assignment

I am trying to create a simple form where user can insert information. If user click send button, information will be displayed.

Here is the code in views.py.

from kay.utils import render_to_response
from myapp.form import ContactForm
from myapp.models import NhanThu
# Create your views here.
@login_required
def index(request):
    form_test = ContactForm()
    if request.method =="POST" and form_test.validate(request.form):
        NhanthuModelbien = NhanThu(subject=ContactForm['subject'])
        NhanthuModelbien.put()
        return redirect(url_for('myapp/index'))


    query = NhanthuModelbien.all().order('-created')
    inthuwhat = query.fetch(20)    
    return render_to_response('myapp/index.html',
                              {'form2': form_test.as_widget(),'inthura': inthuwhat})

I always receive this errorr "UnboundLocalError: local variable 'NhanthuModelbien' referenced before assignment". Can anybody point out what is wrong here?

If the condition request.method =="POST" and form_test.validate(request.form) is false then the variable doesn't get initialized. Then you try to use it when initializing query query = NhanthuModelbien.all().order('-created').

Just declare it and initialize it to a default value before the if.
