I want to use form template to render data for show.
My idea is, to readonly/disable formelements. This works fine, except
with selects. The following three variants of render code do not emit
the keyword disabled to the html text:
f.select :attr, @choices, :include_blank => true,
:disabled => !@condition
f.select :attr, @choices, {:include_blank => true},
:disabled => !@condition
f.select :attr, @choices, {:include_blank => true},
{:disabled => !@condition}
Writing readonly instead if disabled (which seems to be undefined for
select) also doesn''t have any effects.
What is going wrong?

Try
f.select :attr, @choices, {:include_blank => true}, { :disabled =>
!@condition }

This worked for me: <%= f.select :attr, @choices, {}, :include_blank => true, :disabled => !@condition %> I believe the problem lies with the empty hash for the options.

> <%= f.select :attr, > @choices, > {}, > :include_blank => true, > :disabled => !@condition %>It just happens that I''m working on the very same thing again and the problem with the above is that when the select is not disabled it actually does not include the empty option.
