OpenERP Inheritance with customized module

Question

I have a created my own module as Test_Module.

further I have inheritated hr_holidays class and view to Test_Module.

For inheritated view , i added new field Employee_Name.As per design this field pulls out all the employee names from my customized module.

however inheritated view also got Employee field which has come as part of inheritation.

Is there any way to remove this field, employee ?.I don't want to use this field employee , instead i want to use field added by me employee_name,

infact I tried by removing the inheritated field employee but no luck. System throws error saying that user_id doesn't exist in test.base. Further I checked user_id is used in hr_holidays class methods. I would like to know the solution from the experts. Thanks

Answer 1

I was able to resolve this .

Here is the solution:

Added one more class inherited with hr.employee

class hr_employee(osv.osv):
    _name='hr.employee'
    _inherit='hr.employee'
    _columns={




  }   
hr_employee() 

Also made the following changes in test.base

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

_columns={
    'name':fields.many2one('hr.employee','employee_id'),
    'email':fields.char('Email'),
    'code':fields.char('code'),
    'sal':fields.float('Salary'),
    'rate':fields.selection([(10,'10'),(20,'20'),(30,'30')],'rate'),
    'ded':fields.float('ded'),
    'ns':fields.float('Net Salary'),
    'skillid':fields.one2many('test.performance','exp','Skill'),
    'emphistory':fields.many2many('best.base','test_best_rel','emphistory','pc','Employee history'),
    'department_id':fields.integer('Department'),

    }


 class hr_holidays(osv.osv):
    _name='hr.holidays'
    _inherit="hr.holidays"

    _columns={




     }       
    hr_holidays()

Answer 2

In your view definition in the XML file where you inherited from the hr_holidays.edit_holiday_new view you put that to add a new field:

<field name="name" position="after">
    <field name="employee_name" />
</field>

The magic word you need here is replace. When you specify where to put the new field (employee_namein your case) you can put it in the place of the old one:

<field name="name" position="replace">
    <field name="employee_name" />
</field>
