Question

I’m looking for a way to get a random database entry (Video) that has a category_id equal to one I provide.

The code I’m currently using to get random Videos,

def self.random()
  @count = self.count()
  self.find(:first, :offset => rand(count))
end

This code works perfectly for finding a random video, however I need to constrain it to a video that has the :category_id that I provide.

Any help would be appreciated.

Answer 1

It might be something like this

@category = Category.find(params[:id])
@category.videos[rand(count)]

I’m a rails noob, so I don’t know, maybe there is a more efficient way to do this
