Rails model constants with hash

I have added some constants to a model say MyModel.rb as shown below.

MY_CONST = {
  :foo =>"Some Name for Foo",
  :bar =>"Some Na开发者_StackOverflow社区me for Bar"
  }

Also I have saved string foo as the column value in a table record.

@m = MyModel.find(1)
@m.column_name #=> foo

Now in my view I need to show "Some Name for Foo" as the output for @m.column_name instead of foo

I tried MyModel::MY_CONST[:foo] and it prints "Some Name for Foo" as the output. But I don't know how to pass @m.column_name to MyModel::MY_CONST[....] dynamically.

Try

MyModel::MY_CONST[@m.column_name]

or

MyModel::MY_CONST[@m.column_name.to_sym]
