Question

I am trying to use Object.find(params[]) to only return objects with :stage_id = integer

Here is my controller code

def show
    @lesson = Lesson.find(params[:id])
    @stage1 = @lesson.units(params[:stage_id] == 1)
    @stage2 = @lesson.units(params[:stage_id] == 2)

Each lesson has many units, each unit has either a stage_id = 1 or stage_id = 2, I want @stage1 to become an array with units that only have a stage_id value of 1. The same goes for stage2.

How can I properly use params to return only units that have the indicated table values?

Answer 1

def show
  @lesson = Lesson.find(params[:id])
  @stage1 = @lesson.units.first(:conditions => { :stage_id => 1 })
  @stage2 = @lesson.units.first(:conditions => { :stage_id => 2 })
end
