如何獲得字段值，並賦值給變量在python

Question

我使用OpenERP的6。我form包含一個text box，我需要得到該值，並將其賦值給一個變量，從而進行計算並返回一個結果存儲在一個新的textbox ...

Answer 1

我給這裏.py文件。這將計算數量的平方

from osv import osv 
from osv import fields 
class test_base(osv.osv): 
_name='test.base' 

_columns={ 
    'first':fields.integer('Enter Number here'), 
    'result':fields.integer('Display calclation result'), 


    } 
def first_change(self, cr, uid, ids,first,context=None): 

    r=first*first 
    return {'value':{'result':r}} 

test_base() 

XML文件在這裏給出

<?xml version="1.0" encoding="utf-8"?> 
<openerp> 
<data> 

    <record model="ir.ui.view" id="test_base_form"> 
     <field name="name">test.base.form</field> 
      <field name="model">test.base</field> 
      <field name="type">form</field> 
      <field name="arch" type="xml"> 
      <form string="best Base"> 
      <field name="first" on_change="first_change(first)"/> 
      <field name="result"/> 

       </form> 
      </field> 
    </record> 
    <record model="ir.ui.view" id="test_base_tree"> 
     <field name="name">test.base.tree</field> 
      <field name="model">test.base</field> 
      <field name="type">tree</field> 
      <field name="arch" type="xml"> 
      <tree string="Test Base"> 
      <field name="first"/> 
      <field name="result"/> 

       </tree> 
      </field> 
    </record> 

    <record model="ir.actions.act_window" id="action_test_seq"> 
     <field name="name">Test Base</field> 
     <field name="res_model">test.base</field> 
     <field name="view_type">form</field> 
     <field name="view_mode">form,tree</field> 
    </record> 

<menuitem id="menu_test_base_main" name="Test Base">
