openerp - How to update one2many in customers from accounting invoice -

-

i have created one2many customer form. so, when validating (button validate) invoice trying pass values in one2many. have tried many ways , followed odoo forums, having trouble that. using following code: one2many field 'customer_status' in 'res.partner' :

@api.multi  @api.model  def invoice_validate(self):  customer_obj=self.env['res.partner']  customer_id=customer_obj.search([('id','=',self.partner_id.id)])  customer_line=customer_obj.browse(customer_id)  dd = {'policy_number': self.policy_no,}  customer_stat_add = customer_obj.write([customer_line.id],{  'customer_status': [(0, 0, dd)]  })  state_change = self.write({'state': 'open'})  return state_change, customer_stat_add

it gives me error:

valueerror: "invoice_validate() takes 2 arguments (1 given)" while evaluating u'invoice_validate()'

thanks.

buttons w/ new api need @api.multi , if want work on single object can use self.ensure_one();

@api.multi def foo(self):     self.ensure_one()     print self.my_field

also, don't need browse object browse objects w/ new api.

bear in mind if feature odoo base feature must call super().method_name not break ;)

java - Copying object fields -

what best way of copying classes when need have 2 independent variables? have simple class: public class myclass { boolean = false; string b= "not empty"; } do need make method : assign(myclass data ) { a= data.a; b= data.b; } is there automatic method copy (duplicate) objects in java? do need make method : pretty close. instead of making method, should make constructor. such constructors called copy constructor , , create them this: myclass(myclass data) { = data.a; b = data.b; } and create copy of instance, use constructor this: myclass obj1 = new myclass(); myclass obj2 = new myclass(obj1); copy constructor can tedious : using copy constructor create deep-copy can tedious, when class has mutable fields. in case, assignment create copy of reference, , not object itself. have create copy of fields (if want deep copy). can go recursive. a better way create deep copy serialize , deserialize object. why not use clone()? ...

c++ - Clear the memory after returning a vector in a function -

-
i have function processes , stores lot of data in , returns results vector of class. amount of data stored in function tremendous , want clear storage memory of function after finished job. necessary (does function automatically clear memory) or should clear memory function? update: vector<customers> process(char* const *filename, vector<int> id) { vector<customers> list_of_customers; (perform actions) return list_of_customers; } variables defined locally within function automatically released @ end of function scope. destructors objects called, should free memory allocated objects (if objects coded correctly). example of such object std::vector . anything you've allocated new must have corresponding delete release storage. try avoid doing own allocation , use raii instead, i.e. containers or smart pointers.
