Hi all.

I recived error when install module to odoo8:

Traceback (most recent call last):

I removed all code from my project and tried install clean module. I received similar error. Now my project is as follows

[controllers.py]

# -*- coding: utf-8 -*-

from openerp import http

import werkzeug

from openerp.http import request

#import os

#from models import SessionVisitor, SessionFirstVisit

class WebCalc(http.Controller):

      @http.route(['/webcalc/remoteaddr/'], type='json', auth='public', website=True)

      def return_map(self):

            '''For JSON you need restart odoo with - u module_name after all modify'''

            remoteAddr = request.httprequest.environ['REMOTE_ADDR']

            return {'remoteAddr': remoteAddr}

      @http.route(['/web_calc/register_session'], type='json', auth='public', website=True)

      def register_session(self, prevouseURL, currentURL):

            '''For JSON you need restart odoo with - u module_name after all modify'''

            return {'remoteAddr': '192.168.1.1', 'sessionID': 23, 'sessionPing': 20, 'sessionTimout': 10}

      @http.route(['/web_calc/check_session'], type='json', auth='public', website=True)

      def check_session(self, sessionID, prevouseURL, currentURL):

            '''For JSON you need restart odoo with - u module_name after all modify'''

            #remoteAddr = request.httprequest.environ['REMOTE_ADDR']

            return {'remoteAddr': '192.12.122.34'}

[models.py]

# -*- coding: utf-8 -*-

from datetime import timedelta

from openerp import models, fields, api

import datetime

# class web_calc(models.Model):

# _name = 'web_calc.web_calc'

# name = fields.Char()

class SessionVisitor(models.Model):

      _name = 'web_calc.session_visitor'

      clientAddr = fields.Char(string="Client_IP", required=True)

      dateVisit = fields.Date(default=fields.Date.today)

      dateLastCheck = fields.Date(default=fields.Date.today)

      def __init__(self, remoteAddr):

            self.clientAddr = remoteAddr

            self.dateVisit = datetime.now

            self.dateLastCheck = datetime.now

            def setDateLastVisit(self, currentDate):

            self.dateLastCheck = currentDate

Every time when I try to install the module, I get the similar error.

What do I wrong?
