How to insert value to a one2many field in table with create method?

I have created two wizards which are shown below:

from osv import fields, osv
class fee_structure(osv.osv_memory):
_name="fee.structure"
_description="Fee Structure"
_columns={
            'name': fields.char('Title', size=64),
            'area_id': fields.many2one('department.area', 'Area'),
            'grade_id': fields.many2one('department.grade', 'Grade'),
            'fee_template_ids': fields.many2many('department.fee_template', 'fee_structure_template_rel', 'fee_structure_id', 'dept_fee_template_id', 'Templates'),
            'fee_ids': fields.one2many('wizard.fee', 'fee_structure_id','Extra Fee'),
          }

def button_create(self, cr, uid, ids, context={}):
    print '..................button_create................'
    wizard_obj=self.browse(cr, uid, ids, context=context)[0]
    template_ids=[]
    for template_id in wizard_obj.fee_template_ids:
        template_ids.append(template_id.id)
self.pool.get('institution.fee').create(cr, uid, {
                                'name': wizard_obj.name,
                                 'active': True,
                                  'area_id': wizard_obj.area_id.id,
                                   'grade_id': wizard_obj.grade_id.id,
                                   'fee_template_ids': [(6,0,template_ids)],
                                #  needs to add values for field fee_ids here,
                                                      })
fee_structure()

class wizard_fee(osv.osv_memory):
_name="wizard.fee"
_description="Fee Wizard"
_columns={
            'fee_id': fields.many2one('fee.fee', 'Fee'),
            'amount': fields.float('Amount'),
            'fee_structure_id': fields.many2one('fee.structure',  'Fee Structure'),
          }

wizard_fee()

The model institution.fee is

class institution_fee(osv.osv):
_name="institution.fee"
_description="Institution Fee"
_columns={
            'name': fields.char('Fee Name', size=64),
            'active': fields.boolean('Active'),
            'area_id': fields.many2one('department.area', 'Area'),
            'grade_id': fields.many2one('department.grade', 'Grade'),
            'fee_template_ids': fields.many2many('department.fee_template', 'institution_fee_template_rel', 'inst_fee_id', 'dept_fee_template_id', 'Fee Template'),
            'fee_ids': fields.one2many('department.fee_structure', 'inst_fee_id', 'Extra Fee'),
          }
_defaults={
            'active': True
           }
institution_fee()

I have added the values of the many2one field fee_template_ids to model institution.fee , similarly I want to add the values to the one2many field fee_ids using wizard.fee to institution.fee .

The fee.structure wizard is called from a menuitem and its use is to create a fee structure(institution.fee model).

This may help you:

(0, 0,  { values })    link to a new record that needs to be created with the given values dictionary
(1, ID, { values })    update the linked record with id = ID (write *values* on it)
(2, ID)                remove and delete the linked record with id = ID (calls unlink on ID, that will delete the object completely, and the link to it as well)
(3, ID)                cut the link to the linked record with id = ID (delete the relationship between the two objects but does not delete the target object itself)
(4, ID)                link to existing record with id = ID (adds a relationship)
(5)                    unlink all (like using (3,ID) for all linked records)
(6, 0, [IDs])          replace the list of linked IDs (like using (5) then (4,ID) for each ID in the list of IDs)

In your case you need to use (0, 0, { values })

Thanks nazarii..

The only option that takes a list is number 6, right? I cannot do a (4, [id, id, ids]) and have it all been related with my record? Or a (0, 0, [{values}])?

If you want to link new record to existing wizards than yes, you need to use (6, 0, [IDS]). But if you want to create new wizards on the fly and link to this record than use 'fee_ids': [(0, 0, values1), (0, 0, values2) ]

Insert a new record in one2many fields in odoo9.

Code:

@api.multi

def Create_One2many_method(self):

search_var = self.search([('staff_age','=',0)])

search_var.write({

                    'stud_ids': [(0,0, {

                                                'reg_no':4200,

                                                 'stud_email':'anbulove@gmail.com',

                                                   'stud_phone':'9788987689',

 

})]

})

In my case, the wizard should add or relate one or more existing records into the "one2many" field of the new record. Then if I'm not wrong, what I must to do is a (1, ID, { values }) with ID = the id of the fresh new record, right?

but this is what I get :( AttributeError: "'list' object has no attribute 'copy'"
