I have done many variations of this code. Essentially I want this to be
true.
assert_equal '', Org.field_for(nil).display
This is a polymorphic relationship.
fieldable.rb
============
def field_for(purpose)
self.fields.find(
:first,
:conditions => ["purpose LIKE ?", "#{purpose}"],
:order => 'position asc')
end # def
field.rb
========
def display
str = ""
field.to_s unless search.blank?
str
end
Can someone help tell me what I'm doing wrong and why I can't produce an
empty string? I had thought that nil.to_s created an empty string, but
just writing the following didn't work either.
def display
field.to_s
end
Thanks!
