def get_column_names(self, table_name):

query = """
       SELECT column_name
       FROM information_schema.columns
       WHERE table_name = %s
   """
self.env.cr.execute(query, [table_name])
result = self.env.cr.fetchall()
return [(row[0], row[0]) for row in result]


@api.onchange('table_name')
def onchange_table_name(self):
if self.table_name:
    column_names = self.get_column_names(self.table_name)
    columnlist = [(name[0], name[1]) for name in column_names]

self.column_name.selection = [] AttributeError: 'bool' object has no attribute 'selection'

Hi,

You can try using Reference Field in Odoo, which helps you to show data from the records based on model selection.

Sample:

action = fields.Reference(selection=[('ir.actions.report', 'ir.actions.report'),
('ir.actions.act_window', 'ir.actions.act_window'),
('ir.actions.act_url', 'ir.actions.act_url'),
('ir.actions.server', 'ir.actions.server'),
('ir.actions.client', 'ir.actions.client')])


See: Working of reference field in Odoo


Thanks
