How to get selection field value in RML

Question

I have a selection field and I want to print the selected value but I got the key.

Python code:

'transport': fields.selection([('plain','Plain'),
                               ('train','Train'),
                               ('taxi','Taxi'),
                               ('bus','Bus'), 
                               ('sv','Service vehicle')],'Means of transport'),

RML:

[[ o.transport or '']]

When I select Plain the printed value is plain.

How to get Plain in the printed report instead of plain?

We may achieve in two ways.

Direct condition on .rml and
Using function

Direct condition on .rml

For example:

[[ o.transport == 'avion' and 'Avion' or o.transport == 'train' and 'Train' ]]

Using function

We need to add function on report .py file

def _get_value_from_selection_field(self, model, field, value):

    selection = self.pool.get(model)._columns.get(field).selection

    res = ''

    for v in selection:

        if v[0] == value:

            res = v[1]

        break

    return res

Thanks for your answer. I used the RML code but nothing was printed. — Kenly, Mar 13 '16 at 13:37
