Aliasing field names in validators

Rails
1

suppose i have a model:

class Foo
belongs_to :some_customized_bar
validates_presence_of :some_customized_bar_id
end

if i use ‘error_messages_for :foo’ in a view, i’ll get errors like:
“Some customized bar can’t be blank”

is it possible to tell the validator to use another name for that
field, or do i have to do it myself using the model.errors collection?

thanks,
jeff

validates_presence_of :some_customized_bar_id, :message => “RubyonRails
is Awesome”

Jamal – I’m not sure this answered Jeff’s question, which involved
setting another name for the field, I believe. Adding the :message
parameter only affects what’s after the field name, so when a form is
validated, the <%= error_messages_for ‘widget’ %> results in text like

“Some customized bar RubyonRails is Awesome”

Is there a way to also change the field name (or not have it show up
at all?)

Thanks Jamal, and thanks Jeff for asking the question :slight_smile:
