From the code responsible of this witch located in fields.Selection
class
There is no way to do it
without using special tricks:
# frame code
def _setup_attrs(self, model, name):
super(Selection, self)._setup_attrs(model, name)
# determine selection (applying 'selection_add' extensions)
for field in reversed(resolve_mro(model, name, self._can_setup_from)):
# We cannot use field.selection or field.selection_add here
# because those attributes are overridden by ``_setup_attrs``.
if 'selection' in field.args:
self.selection = field.args['selection']
if 'selection_add' in field.args:
# use an OrderedDict to update existing values
selection_add = field.args['selection_add']
self.selection = OrderedDict(self.selection + selection_add).items()
Like for example monkey patching I tried normal inheritance
It didn't work I think It needs a lot of work.
This what I tried and it worked just fine in Odoo 9. I created a new key is selection_add_after
witch is a dictionary
1. key is the value of selection that you want to add item after it
2. value is the list of selection items that you want to add
def _setup_attrs(self, model, name):
super(fields.Selection, self)._setup_attrs(model, name)
# determine selection (applying 'selection_add' extensions)
for field in reversed(fields.resolve_mro(model, name, self._can_setup_from)):
# We cannot use field.selection or field.selection_add here
# because those attributes are overridden by ``_setup_attrs``.
if 'selection' in field.args:
self.selection = field.args['selection']
if 'selection_add' in field.args:
# use an OrderedDict to update existing values
selection_add = field.args['selection_add']
self.selection = OrderedDict(self.selection + selection_add).items()
if 'selection_add_after' in field.args:
selection_add_atfer = field.args['selection_add_after']
new_selection = []
for item in self.selection:
new_selection.append(item) # add the element firs
items_to_add = selection_add_atfer.get(item[0], [])
for item_to_add in items_to_add: # then add the element if there is
new_selection.append(item_to_add)
# I don't know why they used OrderdedDict ???!! do you have any idea why?!!
self.selection = OrderedDict(new_selection).items()
# mucky patch the method in selection field
fields.Selection._setup_attrs = _setup_attrs
Make sure you patch before defining the field
# add element after draft
state = fields.Selection(selection_add_after={'draft': [('hello', 'Hello')]})
# add element after draft and other emelent after confirmed
state = fields.Selection(selection_add_after={'draft': [('hello', 'Hello')], 'confirmed': [('test','Test')]})
You can add new key like removing or anything you want.
But monkey patching Framework method is also a bad idea because if there is any updates in the _setup_attrs
is always
removed by this.
EDIT
For Odoo 11, this is the code:
def _setup_attrs(self, model, name):
super(fields.Selection, self)._setup_attrs(model, name)
# determine selection (applying 'selection_add' extensions)
for field in reversed(fields.resolve_mro(model, name, self._can_setup_from)):
# We cannot use field.selection or field.selection_add here
# because those attributes are overridden by ``_setup_attrs``.
if 'selection' in field.args:
self.selection = field.args['selection']
if 'selection_add' in field.args:
# use an OrderedDict to update existing values
selection_add = field.args['selection_add']
self.selection = list(OrderedDict(self.selection + selection_add).items())
if 'selection_add_after' in field.args:
selection_add_atfer = field.args['selection_add_after']
new_selection = []
for item in self.selection:
new_selection.append(item) # add the element firs
items_to_add = selection_add_atfer.get(item[0], [])
for item_to_add in items_to_add: # then add the element if there is
new_selection.append(item_to_add)
# I don't know why they used OrderdedDict ???!! do you have any idea why?!!
self.selection = list(OrderedDict(new_selection).items())
fields.Selection._setup_attrs = _setup_attrs
