Hello,
You can create a compute char field [selection_str = fields.Char(compute="comp_str")]

def comp_str (self):        

    self. selection_str = dict(self._fields['select_val']._description_selection(self.env)).get(self.celect_val)

Approach #1:
make a global dictionary for converting like:

SELECTION = {'A': 'Apple', ...}

and use SELECTION[obj.select_var] wherever you need the string.

Approach 2#:

selected_string = fields.Char(compute="_compute_string", store=False)

def _compute_string(self):

    for rec in self:

        rec.selected_string = dict(self._fields.get('select_var').selection).get(rec.select_var)

Hello Vinoth N,

Please find below code it may help you to resolve this issue,


print dict(self._fields['select_val'].selection).get(self.select_val)
