Copy one2many field SNAFU - odoo

Question

I need to show record from notebook project on notebook sheet , but the showed record is not according to project
My py :
class notebook_project(osv.osv):
_name = "notebook.project"
_description = "Notebook Project ID"
def onchange_project(self, cr, uid, ids, project, arg, context=None):
if project :
proj = self.pool.get('project.project').browse(cr, uid, project, context=context)
return {'value': {'name': proj.name}}
return {}
_columns = {
'name' : fields.char('Name', size=64),
'project' : fields.many2one('project.project', 'Project'),
'notebook_project_lines' : fields.one2many('notebook.project', 'notebook_project_id', 'Members Lines'),
'notebook_project_id': fields.many2one('notebook.project', 'Parent Project', ondelete='cascade', select=True),
'member' : fields.many2one('hr.employee', 'Members'),
}
notebook_project()
class notebook_sheet(osv.osv):
_name = "notebook.sheet"
_description = "Notebook Project Sheet"
def onchange_notebook_project(self, cr, uid, ids, notebook_project, context=None):
res = {}
employee_lines = []
if not notebook_project : return {}
if notebook_project :
notebook_project_obj = self.pool.get('notebook.project').browse(cr, uid, notebook_project)
for p in notebook_project_obj.notebook_project_lines:
employee_lines.append((0,0,{'notebook_sheet_lines':p.id
}))#this dict contain keys which are fields of one2many field
res['notebook_sheet_lines']=employee_lines
return res
def onchange_project(self, cr, uid, ids, project, context=None):
if project :
proj = self.pool.get('project.project').browse(cr, uid, project, context=context)
return {'value': {'name': proj.name}}
return {}
#def create(self, cr, user, vals, context={}):
#first model
# notebook_project_obj = self.pool.get('notebook.project')
#browse and get o2m fields, according to your selected project(id)
# notebook_project_lines = notebook_project_obj.browse(cr, user, ['notebook_project_id'])[0].lines
#copy first o2m model to second o2m model
# for line in notebook_project_lines :
# vals['notebook_sheet_lines'].append([0, False, {'notebook_project_lines':line.employee_id.id,}])
# return super(notebook_sheet, self).create(cr, user, vals, context)
_columns = {
'name' : fields.char('Name', size=64),
'notebook_sheet_lines' : fields.many2many('notebook.project', 'notebook_project_sheet_rel', 'notebook_project', 'notebook_project_id'),
'notebook_project': fields.many2one('notebook.project', 'Project ID',domain=[('notebook_project_id','=',False)]),
'project' : fields.many2one('project.project', 'Project'),
'member' : fields.many2one('hr.employee', 'Members'),
}
notebook_sheet()
Edited my answer , Mr. AnomA . Still not sure about many2many , please kindly check it
Do i need to change the onhange event as well ? thanks again in advance

Answer 1

First of all please create a link between notebook.sheet and notebook.project. Now there is no link between these 2 models. Add a many2one relation to notebook.sheet in notebook.project and then change the relation id in notebook_sheets_lines to this field.
Otherwise change the relation type of notebook_sheet_lines to many2many.
Then change the onchange_notebok_project() which will return {'value':{'notebook_sheet_lines':LIST_OF_EMPOYEEIDS}}
Also No need to add many2many in motebook_project.
