Get values from array returned from model

Question

I have an array that is returned from a model that does not correspond to the view/controller. (i.e Data is from Foo, while I'm in '/bar/'). Therefore I cannot access them via the conventional

params[:someItem]

So I am trying to extract values like this

someVariable = @array[0]

However I get a scrambled mess:

#<Promotion:0x3b74140>

Seeing as that the value I want is an int, I tried calling .to_i, which threw a No Such Method error. Calling to_int gave the same result.

Question: How do I get this value out of the array? And as an aside, why do .to_i and .to_int not work??

As per my understanding, You are trying to access Array of model objects. When you write

someVariable = @array[0]

then it will give you the first model object from @array. If you want to access object values then you can use like this

modelObj = @array[0]
someVariable = modelObj.my_attribue_name

Ahh! Its an array of OBJECTS! Thanks, I thought it was an int array. That solves it.
