I am fairly new to full stack development and I am trying to get a simple search form to work. The webpage is supposed to redirect the user to a page with a list of all videos containing the keyword. Whenever I type in a title that exists, I get :NoMethodError at /posts/:title/search

I've tried using a query but have failed.

This is my app.rb. I query all videos that contain :title.

get "/posts/:title/search" do # authenticate! @results = Video.all(title: params[:title]) if @results erb :search_success else flash[:error] = "Video not found." erb :search_success end end

This is search_success.erb where I want to have a list of the videos that contains the keyword in the title.

This is navigation.erb where the search form lives.

Try changing

@results = Video.all(title: params[:title])

@results = Video.all(:title.like => "%#{params[:title])}%")

Also in your search form, you have two type attributes. You should change one of them to
