openErp 6.1 AttributeError: 'NoneType' object has no attribute '_columns' at custom module installation

Question

I'm trying to solve an installation problem on a custom module in openERP 6.1.

I'm getting this error:

    Server Traceback (most recent call last):

I asume that's a problem on my model definition, but I'm not able to found where is the problem.

This is the model code:

 from osv import osv, fields 
from tools.translate import _

from datetime import date

import time


class adventure_sports_sport_type(osv.osv):
    _name = 'adventure_sports.sport_type'
    _columns = {
        'name': fields.char('name', size=64, required=True, translate=True, help='The name of the sport'),
        'level': fields.selection([('aHigh', 'High'), ('aMedium', 'Medium'), ('cLow', 'Low')], 'level',
                                  required=True),
        'activities': fields.one2many('adventure_sports.activity', 'sport_type_id', 'Activities')
    }
    _defaults = {
        'level': lambda *a: 'medium',
    }
    _order = 'name, level'
adventure_sports_sport_type()


class adventure_sports_activity(osv.osv):
    _name = 'adventure_sports.activity'
    _columns = {
        'name': fields.char('Activity name', size=64, required=True, translate=True, help='The name of the activity'),
        'sport_type_id': fields.many2one('adventure_sports.sport_type', 'Sport type', ondelete='cascade',
                                         help='sport_type_id'),
        'current': fields.boolean('Current'),
        'is_available_monday': fields.boolean('Monday'),
        'is_available_tuesday': fields.boolean('Tuesday'),
        'is_available_wednesday': fields.boolean('Wednesday'),
        'is_available_thursday': fields.boolean('Thursday'),
        'is_available_friday': fields.boolean('Friday'),
        'is_available_saturday': fields.boolean('Saturday'),
        'is_available_sunday': fields.boolean('Sunday'),
        'start_time': fields.float('Start time'),
        'end_time': fields.float('End time'),
        'images': fields.one2many('adventure_sports.image', 'activity_id', 'Images'),
    }
    _defaults = {
        'is_active': True,
    }
adventure_sports_activity()


class adventure_sports_activity_image(osv.osv):
    _name = 'adventure_sports.activity_image'
    _columns = {
        'image': fields.binary('Image', filters='*.png,*.jpg,*.gif'),
        'description': fields.char('Description', size=500, required=True, translate=True),
        'activity_id': fields.many2one('adventure_sports.activity', 'Activity', readonly=True)
    }
adventure_sports_activity_image()

And this is my __openerp__.py file:

    'author': 'Unknow',

    'depends': ['base'],
    'init_xml': [],
    'update_xml': ['adventure_sports.xml'],
    'demo_xml': [],
    'installable': True
}

I've checked the module dependencies in the openerp.py file and everything seems to be ok.

Please, can anybody help me?

Thanks a lot.

Answer 1

Solved! it was a spelling problem in the xml:

I changed this:

<record model="ir.actions.act_windows" id="action_activities_catalog">
        <field name="name">action.activities.catalog</field>
        <field name="res_model">adventure_sports.activity</field>
        <field name="view_type">form</field>
        <field name="view_mode">search,tree</field>
 </record>

For this:

<record model="ir.actions.act_window" id="action_activities_catalog">
        <field name="name">action.activities.catalog</field>
        <field name="res_model">adventure_sports.activity</field>
        <field name="view_type">form</field>
        <field name="view_mode">search,tree</field>
 </record>
