def button_dummy(self, cr, uid, ids, context=None):
          res = []
          valiue = {}
          print "employee",context,ids
          ename = context.get('employee_id');         
          emp_obj = self.pool.get('hr.employee')
          emp_name = emp_obj.search(cr, uid, [('name','=',ename)], context=context)
          print "emp_name",emp_name
          location_lines = []
          location_ids = self.pool.get('employee.location').search(cr, uid, [('employee_id','=',emp_name)],limit=5)
          for p in self.pool.get('employee.location').browse(cr, uid, location_ids):
            ## First i used this return to update the one2many field, but no output
          return res

         ## Second i used this return to update the one2many field, but no output

          return {'value': {'location_line_ids': location_lines}}

How can i return values into one2many field using button click?


Updated question:

First i created employee.location model. Then i call employee.location(one2many) model in hr.employee. In employee.location there is a many2one employee_id field to connect both the models.

Already i added datas in employee.location using different form view. Now i just want to see the history of the employee location in the employee profile. For that

<button name="button_dummy" string="Refresh" type="object" context="{'employee_id':name,'location_line_ids':location_line_ids}"/>                      
                         <field name="location_line_ids" options="{'reload_on_button': true}">


When i click the button above function will call and just display the employee location data for only displaying. I dont want to write the datas again, only want to display the datas in each employee profile using employee_id.



I have edited my ans, check it. Let me know if that works or not. You don't need any button click. Just put the field in as shown in my ans.

Thanks for your reply. I have two different menu: HR-Employee and another is Employee location. In Employee location i will add the locations against each employees. Then i need an extra addons- ie, i want to see the history of these employee locations in each employee profile. So i added employee location as one2many in my employee profile. And added a button click. For an example, i added 3 records of employee sam in Employee location. Next i select HR-employee and select sam, there is a one2many field in sam's(employee profile). Above to the one2many field there is button. when i click the button it will select 3 records from the employee.location table, and will just display the records in the one2many field. I need this requirement. Do you understand my requirement?

You will directly update the values using the 'write' method, returning 'value' will not work. This is not 'onchange' method.

1./ Also, here you tried to find the location based on the 'employee_id' which could be a many2one field and you have tried searching as 'employee_id' ,'=',emp_name, that is an integer value and you are trying to search by 'string' value. I am wondering whether this is working for you or not.

2./ Where does 'project_ids' came from in the loop? I think it should be 'location_ids'.

Anyways, try following:

for p in self.pool.get('employee.location').browse(cr, uid, project_ids):

Once everything is stored in location_lines then you have to update that value using 'write' method



I don't think you need any button click, just to display the employee location. System will autmatically display all those values based on the relation.
Just put your field as shown below in your view, wherever you need it.

<field name="location_line_ids">
<tree string="Employee Locations">
    <<Your Fields From The Model 'employee.location'>>


Hope this helps !!.
