[Rails] noob question

Hi *,

I am writing my first app based on the ''depot'' application but
with some
suttle differences to help me learn.

I am a bit sutck with following and would be grateful for any help:

I have the following controller:

class MainController < ApplicationController

def index
    @objects = Object.certified_items
  end
end

This relates to a field called ''certified'' within a table
called
objects. The certified field contains an ''int'' of either 0 or
1 - these
will become Y/N checkboxes.

Within my model I have the following:

  def self.certified_items
    find(:all,
         :conditions => "certified < 1", 
  end
end

What I am trying to do is use certified as a boolean for yes or no. So
if something is not certified ''0'' don''t display it -
if it is cerified
''Y'' then do display it.


Cheers,
Luke

Hey luke,

Not quite sure what your question is...

You may have your greater/less than the wrong way round? Your
certified_items returns non certified items at the moment. I assume
you know theres a typo with a missing bracket and an extra comma there
too.

def certified?
  self.certified==1
end

will return true or false which will be cleaner to use in your
controller if you need to test their certifiedness after extraction
from the db.

[Rails] noob question

You also can''t use a model named Object, Rails won''t allow it.
( I
don''t know if that was just supposed to be a generic example ...)

And in your model:

 def self.certified_items
   find(:all, :conditions => "certified = 1",
 end

But, like Henry, I''m not exactly sure what the question is...

[Rails] noob question

Hi Jeff & Henry,

Thanks for your help :)

Here is what worked in the end:

class MainController < ApplicationController
  def index
   @handsets = Handset.certified_items
  end


class Handset < ActiveRecord::Base

def self.certified_items
  find(:all,
       :conditions => "certified =1") 
 end
end

Cheers,
Luke
