2nd what I want is when someone selects the field it should give another option on selection which is not happening (though it is giving some field but 2nd field throws an error)!

推荐答案

参考字段主要用于显示不同模型的记录，以作为记录中的参考.例如，您已经创建了一个模型，以便每当创建并保存销售订单，采购订单，交货订单，项目等时，都应在模型中创建一条包含用户名，日期和一些注释之类的数据的新记录.因此，您在此处添加一个参考字段，该参考字段链接到创建记录的原始记录(销售订单，采购订单等).您可以在openerp 6的res.request模型中找到它

Reference fields are mainly used for showing different model's records as reference in your record. For example you have created a model such that whenever a sale order, purchase order, delivery order, project etc are created and saved, then a new record with data like user name, date, some notes should be created in your model. So here you add a reference field which link to the original record(sale order, purchase order etc) from which your record is created. You can find this in res.request model in openerp 6

要在您的班级中创建参考字段

To create an reference field in your class

def _get_selection_list(self, cr, uid, context=None):
    #@return a list of tuples. tuples containing model name and name of the record
    model_pool = self.pool.get('ir.model')
    ids = model_pool.search(cr, uid, [('name','not ilike','.')])
    res = model_pool.read(cr, uid, ids, ['model', 'name'])
    return [(r['model'], r['name']) for r in res] +  [('','')]

_columns = {
    'ref': fields.reference(Reference', selection=_get_selection_list, size=128)
}
