Openerp中的客户端验证 [英] Client side validation in openerp

问题描述

我仍在学习Openerp，如果我问的很简单，请忍受. 我的问题是我需要验证两个代表start_time和end_time的字段.

I am still learning Openerp and please bear it if I asked something very simple. My issue is that I need to get validate two fields which represent start_time and end_time.

两个字段均位于char

both fields are in char

'start_time': fields.char('Start Time'),
'end_time': fields.char('End Time'),

我需要做的是，一旦用户输入了此开始时间和结束时间，我就需要检查该输入是否在24小时内以 hh:mm 模式进行.

What I need to do is , once the user input this start_time and end_time I need to check if that input is in 24hrs and in hh:mm pattern.

请足够友好地帮助我

推荐答案

您应该在Python代码中添加on_change函数，以检查start_time和end_time的格式是否正确.并且在您的xml中，您必须告诉您在字段更改时应调用该方法.

You should add an on_change function to your python code where you check if start_time and end_time is in the correct format. And in your xml you'll have to tell that the method should be called when the field changes.

XML

<field name="start_time" on_change="check_hour_format(start_time)"/>
<field name="end_time" on_change="check_hour_format(end_time)"/>

Python

结果应该类似于

def check_hour_format(self,cr,uid,ids,time_field,context=None):
    if correct format  
       return {}
    else:
        warning = {'title'  : _("Warning for this value!"),
                   'message': _("Field not in correct format!"),
                  }
        return {'warning': warning}

此代码应可解决此问题

import time
    def check_hour_format(self,cr,uid,ids,time_field,context=None):
        try:
            time.strptime(char_input, "%H:%M")
            return {}
        except ValueError:
            warning = {'title'  : _("Warning for this value!"),
                       'message': _("Field not in correct format!"),
                      }
            return {'warning': warning}

在on_change方法中，您可以更改字段值

def on_change(self, cr, uid, ids, context=None):
    # do something
    return {'value': { 'field_name': newValue},
            'warning': {'title': _("Warning"),
                        'message': _("warning message")
                       }
           }
