我有三个模型,Subscription
,Show
和Episode
。 Subscription
的作用是解析其:url
列中的Feed并实例化Show
和Episode
,并使用Feedjira属性填充其列。
我只能在访问shows/1/episodes/1
时才能访问剧集,在<%= render @show.episodes %>
节目视图中使用Shows
无法正常工作且无法使用Comment
给出任何错误。
在Rails入门指南中,他们使用此作为@article = Article.find(params[:article_id])
@comment = @article.comments.create(comment_params)
redirect_to article_path(@article)
创建方法,允许这样做。
def create
@subscription = Subscription.new(subscription_params)
if @subscription.save
@show = Show.new
@episodes = []
# Feed
@feed = Feedjira::Feed.fetch_and_parse @subscription.url
# Show
@show.title = @feed.title
@show.description = @feed.description
@show.genre = @feed.itunes_categories
@show.url = @feed.url
@show.logo = @feed.itunes_image
@show.save
# Episode
@feed.entries.each do |item|
@episodes.push(item)
end
@episodes.each do |item|
@episode = @show.episodes.create
@episode.title = item.title
@episode.description = item.summary
@episode.release_date = item.published
@episode.show_id = @show
@episode.save
end
redirect_to @subscription
end
end
是否缺少引起这种情况的障碍?如果是这样,我将如何在此方法中使用params?
episodes/_episode.hmtl.erb
<ul>
<li>
<%= episode.title %>
</li>
<li>
<%= episode.description %>
</li>
<li>
<%= episode.url %>
</li>
<li>
<%= episode.release_date %>
</li>
<li>
<%= episode.show_id %>
</li>
</ul>
shows/show.html.erb
<h1>Showing Show</h1>
<h2><%= @show.title %></h2>
<%= render @show.episodes %>
routes.rb
添加我的路线和模型,以防出现问题:
Rails.application.routes.draw do
resources :shows do
resources :episodes
end
resources :subscriptions
root 'subscriptions#index'
end
show.rb
class Show < ActiveRecord::Base
has_many :episodes, dependent: :destroy
end
episode.rb
class Episode < ActiveRecord::Base
belongs_to :show
end
subscription.rb
class Subscription < ActiveRecord::Base
validates :url, uniqueness: true
end
.into_iter()
答案 0 :(得分:0)
似乎你需要改变
<%= render @show.episodes %>
到
<%= render partial: "episodes/episode", collection: @show.episodes %>

小建议:不要把你的逻辑放在控制器里。
