Passing database querying tests using spec?

Question

I am learning rspec and databases and have one movie database with the following schema. I'd like to know how to get this test to pass since my efforts seem to be futile. If you need any additional info please let me know in case I'm leaving something vital out that would be helpful:

Schema

 create_table "movies", force: true do |t|
   t.string   "title",      null: false
   t.integer  "year",       null: false
   t.text     "synopsis"
   t.integer  "rating"
   t.datetime "created_at"
   t.datetime "updated_at"
   t.integer  "genre_id",   null: false
   t.in
end

create_table "genres", force: true do |t|
    t.string   "name",       null: false
    t.datetime "created_at"
    t.datetime "updated_at"
  end

Model setup:

class Movie < ActiveRecord::Base
  validates_presence_of :title
  validates_presence_of :year
  validates_presence_of :genre

  has_many :cast_members
  has_many :actors, through: :cast_members

  belongs_to :genre
  belongs_to :studio

Rspec test:

it "partially matches movie titles" do
  results = Movie.search('Manhat')

  expect(results.count).to eq(2)
  expect(results.include?(manhattan)).to be_true
  expect(results.include?(mystery)).to be_true
end

Rspec test argument input:

.create(:movie, title: "Manhattan Murder Mystery"

Code I've tried several variations of so far:

class Movie < ActiveRecord::Base

etc, above..

def self.search(query)  
  select('title').where('title ilike ? OR synopsis ilike ?','%query%', '%query%')
end

Answer 1

You are not passing the parameter to the query. You are always searching for results containing "query". What you should do is:

select('title').where('title ilike ? OR synopsis ilike ?',"%#{query}%", "%#{query}%")

This will substitute the "#{query}" with the parameter passed to the search method.
