Question

hello for my app I need to save a record that the user type, for example if an user type in:

<p><%= f.label :fruit %><br />
<%= f.file_field :fruit%></p>

"apple"

in the show page I need that record appears like

"bag of "+ :fuit

, but I don’t want to save “bag of”, how can I put that text when the user is in the show page??
I have read something about the filters but I don’t understand so much I’m pretty new in rails

if you need more info (like code) just tell me, thanks

EDIT
for now in my model I have this

before_save: add_bag

def add_bag
  self.fruit = ("bag of" + self.fruit)
end

but that save all this “bag of apple”

Answer 1

I recommend you do something like this (assuming your model is Foo)

class Foo < ActiveRecord::Base
  def bag
    "bag of #{fruit}"
  end
end

foo = Foo.new
foo.fruit = "apple"
puts foo.fruit # => "apple"
puts foo.bag   # => "bag of apple"

Is this what you want?
