Question

I’m trying to make query in RoR, but my conditions are coming from params and changing dynamically.

I’ve tried this:

@userlist = User.find(:all, conditions:{(name:params[:name] if params[:name] != nil), (lastname:params[:lastname] if params[:lastname] != nil)})

It’s just my imagination, but shows what I mean.

thanx

Answer 1

If you’re on Rails 3:

@userlist = User.scoped
@userlist = @userlist.where(name: params[:name]) if params[:name].present?
@userlist = @userlist.where(lastname: params[:lastname]) if params[:lastname].present?

etc..
