NameError: name '_' is not defined

[Simon Davies]

Hi

I am getting the above error after installing appengine admin. I am
running appengine patch with appengine and django on Windows Vista.

My model code looks like this:

from google.appengine.ext import db
from django import forms
from django.forms import ModelForm
from django.forms import fields
import appengine_admin

class Contract(db.Model):
forenames = db.StringProperty(verbose_name="forenames")
surname = db.StringProperty(verbose_name="surname")
title = db.StringProperty(verbose_name="title")

class AdminContract(appengine_admin.ModelAdmin):
model = Contract
listFields = ('forenames', 'surname')
editFields = ('forenames', 'surname')
#readonlyFields = (,)

appengine_admin.register(AdminContract)

The full traceback is below:

Any help would be greatly appreciated as frankly I'm rather mystified
as to whats causing this.

Hi,

There was one import statement missing in admin_forms.py

Take the latest appengine_admin version (revision 111) from SVN (How to: http://code.google.com/p/appengine-admin/source/checkout).

Please let us know if the problem was fixed for you.

Hi Valts

Thanks for the reply, but now I'm getting something else with this
error:

__init__() takes exactly 1 argument (2 given)

This is the traceback:

Thanks

Simon

Hi, Simon,

This traceback is not really helpful. It might be appengine patch related issue or something specific to your setup.

Maybe I could help you if you zipped your project folder and either sent it to me personally or put it somewhere temporarily online.
