ruby-on-rails - Rails 5 应用程序 NoMethodError（nil:NilClass 的未定义方法 `take'）部署到 Heroku，即使应用程序成功启动并在本地运行
问题描述
请帮忙。我试图部署，但我不断收到此错误：
Ruby 2.5.1、Rails 5.2.1
NoMethodError (undefined method取'为 nil:NilClass)`
这是我在运行 heroku logs --tail 后得到的结果

它似乎是。欢迎控制器的问题。这是控制器
class WelcomeController < ApplicationController
def index
parsed_response = Tv.get_popular_shows
popular_shows = parsed_response['results'].take(8)
pages = parsed_response['total_pages']
render :index, locals: {
parsed_response: parsed_response,
popular_shows: popular_shows,
pages: pages
}
end
end
这是欢迎索引视图文件
<h1 class="w3-center">TVs' Most Popular</h1>
<section class="w3-content">
<% popular_shows.each do |show| %>
<%= link_to image_tag("https://image.tmdb.org/t/p/w200/#{show['poster_path']}", :alt => "#{show['original_name']} image.", class: "poster w3-image w3-padding w3-card"), root_url + 'tvs/show?' + {tvid: show['id']}.to_param, method: :get %>

以下是 get_popular_shows 的定义方式：
class Tv < ApplicationRecord
include HTTParty
base_uri 'https://api.themoviedb.org/3'
default_params api_key: ENV['API_KEY']
format :json
def Tv.get_all_shows(page, sort)
get("/discover/tv", query: {sort_by: sort, page: page})
end
def Tv.get_popular_shows
get("/discover/tv", query: {sort_by: "popularity.desc"})
end
def Tv.get_single_show(tv_id)
get("/tv/#{tv_id}",query: {})
end
end
这根本不符合逻辑。该应用程序在本地运行并在 Heroku 上启动。我阅读并尝试了很多解决方案均无济于事。我不知道从这里去哪里。任何帮助都感激不尽。提前致谢。
