Client Side Validation In Openerp

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. both fi

Solution 1:

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

<fieldname="start_time"on_change="check_hour_format(start_time)"/><fieldname="end_time"on_change="check_hour_format(end_time)"/>

Python

the result should be something like

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

This code should work for this issue

import time
    defcheck_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}

In on_change method, you can change field value

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