我一直在研究 Edx 问题 Homeowrk 2 大约 2 小时。我正式卡住了。你怎么做东西。这个问题与
我要做的是将电影标题链接到排序,以便它按顺序对电影进行排序。
-#  This file is app/views/movies/index.html.haml
%h1 All Movies
%table#movies
  %thead
    %tr
      %th= link_to 'Movie Title', new_movie_path
      %th Rating
      %th Release Date
      %th More Info
  %tbody
    - @movies.each do |movie|
      %tr
        %td= movie.title 
        %td= movie.rating
        %td= movie.release_date
        %td= link_to "More about #{movie.title}", movie_path(movie)
= link_to 'Add new movie', new_movie_path
根据作业,我应该编辑索引,以便将“所有电影”按顺序排列。我查找了 ruby 的排序方法,它是 movie.order()。我不知道在括号里放什么。
class MoviesController < ApplicationController
  def show
    id = params[:id] # retrieve movie ID from URI route
    @movie = Movie.find(id) # look up movie by unique ID
    # will render app/views/movies/show.<extension> by default
  end
  def index
    @movies = Movie.order(id)
  end
  def new
    # default: render 'new' template
  end
  def create
    @movie = Movie.create!(params[:movie])
    flash[:notice] = "#{@movie.title} was successfully created."
    redirect_to movies_path
  end
  def edit
    @movie = Movie.find params[:id]
  end
  def update
    @movie = Movie.find params[:id]
    @movie.update_attributes!(params[:movie])
    flash[:notice] = "#{@movie.title} was successfully updated."
    redirect_to movie_path(@movie)
  end
  def destroy
    @movie = Movie.find(params[:id])
    @movie.destroy
    flash[:notice] = "Movie '#{@movie.title}' deleted."
    redirect_to movies_path
  end
end
所以根本问题,我不知道如何正确编辑方法索引以给出我的“电影”目录顺序,也不知道如何将标题电影标题分配给索引。
