How to copy() or create a One2many field?

Question

I am duplicating projects and tasks, in that process, the one2many fields should also be duplicated.
I am using the create function instead of copy() function for duplicating the projects and tasks
This is the One2many field that i want to duplicate:
predecessor_ids = fields.One2many('project.task.predecessor', 'task_id', 'Links' ,copy=True)

Hi,
Using the self you can iterate over the one2many lines and create a record in the one2many line model calling its create function and in the dictionary pass task_id as the id of the newly created task.

Thanks

In the dictionary you use to create, add the key for predecessor_ids as
' predecessor_ids ': [(0,0,{
' project.task.predecessor field1 ': line.  field1,
' project.task.predecessor field2 ': line.  field2,
})for line in self. predecessor_ids ]
