在OpenErp中创建一个功能字段

Question

如何在OpenERP中创建功能字段？

看来我需要在python中创建函数,然后用XML调用它.我看到需要编辑的XML,但python代码进入的文件是什么？

Answer 1

py文件的代码..

class some_model(osv.osv):

    _name = 'some.model'

    def Method_of_Function(self, cr, uid, ids, fld_name, arg, context=None):
        #Logic
        return value 

    _columns = {
        "functional_filed":fields.function(Method_of_Function, 
                   method=True,type='int',string='Label', store=True),

    }
some_model()

并在xml文件中记录标签看起来像......

<record model="ir.ui.view" id="object_name_form_view">
        <field name="name">objectname.form</field>
        <field name="model">some.model</field>
        <field name="type">form</field>
        <field name="arch" type="xml">
            <form string="form_string">
                <field name="functional_filed" />
            </form>
        </field>
    </record>
