    Comment on it

    Creating a module in OpenErp 7.0 is quite different from how it has been in 6.1. Already discussed earlier to create a module in version 6.1, its time to throw some light on a basic module created in OpenErp 7.0.

    To start with the basic structure its same as usual:

    __init__.py

    __openerp__.py

    model.py

    model_view.xml

    I created a module named test.

    The __init__.py loads your model classes as usual.

    import demo
    

    The openerp.py is slightly different. Here the attributes have been changed and to parse the view files the attribute is now data.

    {
        'name' : 'Demo',
        'version' : '1.1',
        'author' : 'OpenERP SA',
        'category' : 'Tools',
        'description' : 'First module in 7.0',
        'website': 'http://www.evontech.com',
        'images' : [],
        'depends' : ['base_setup'],
        'data': ['demo_view.xml'],
        'installable': True,
        'auto_install': False,
    }
    

    In your model.py there is the only difference in importing the packages, rest is the same. Note line

    from openerp.osv import fields, osv, orm

    import time
    from lxml import etree
    import openerp.addons.decimal_precision as dp
    import openerp.exceptions
    
    from openerp import netsvc
    from openerp import pooler
    from openerp.osv import fields, osv, orm
    from openerp.tools.translate import _
    
    class demo(osv.osv):
        _name = 'demo'
        _columns = {
                        'name':fields.char('Name', size=50),
                        'active':fields.boolean('Active'),
                        'age':fields.integer('Age'),
                        'gender':fields.selection([('male','Male'),('female','Female')],'Gender'),
                        'job':fields.many2one('occupation','Occupation'),
                        'note':fields.text('Note',size=300),
    
                    }
    demo()
    
    class occupation(osv.osv):
        _name = 'occupation'
        _columns = {
                        'name':fields.char('Occupation', size=100),
                        'active':fields.boolean('Active'),
                    }
    occupation()
    

    Now time to create a view file. Here the major changes will be:

    a) when defining the form you have to mention the version attribute as version="7.0"

    b) We don't create menus the same way here, you each menu item should have its own action and that too defined in a different manner, note the action_job_tree in the action record.

    c) Providing help on a field is a new thing, note: field help of type="html"

    with class="oe_view_nocontent_create"
