I built a feature in my app to allow users to search for images

  • 0

I built a feature in my app to allow users to search for images that would search the image description,member who uploaded it, and image tags but I have this weird issue where if I search for the name ‘jason’ it breaks, but a name like ‘jesse’ works just fine.

Here is my controller

  def search_results
    @tattoos = Tattoo.where("description LIKE ?", "%#{params[:search]}%") | Tattoo.tagged_with("#{params[:search]}", :any => true ) | Member.where("membername LIKE ?", "%#{params[:search]}%").order("created_at DESC").page(params[:page]).per(10)
  end

if i search for ‘jason’ my app breaks, giving me an ‘undefined method’ error and the console shows a bunch of stuff not shown if I searched for say, ‘jesse’. Im not entirely sure how to word that but here is what I mean.

    One thing I noticed is that you are using | instead of || in

    @tattoos = Tattoo.where("description LIKE ?", "%#{params[:search]}%") | Tattoo.tagged_with("#{params[:search]}", :any => true ) | Member.where("membername LIKE ?", "%#{params[:search]}%").order("created_at DESC").page(params[:page]).per(10)

    perhaps that might be part of the issue?
