ruby-on-rails - Rails 4 - 无法在生产中使用动态错误页面呈现 404(故障安全响应期间出错 : Missing template errors/show)

我按照此处的说明创建了动态错误页面: http://wearestac.com/blog/dynamic-error-pages-in-rails

当我通过/404 或/500 直接访问它们时,或者如果我尝试访问路由中未处理的 URL,它们会起作用。但是,当我尝试在 production 中使用 render :status => 404 强制执行 404 操作时,我收到以下错误:

Error during failsafe response: Missing template errors/show, application/show with {:locale=>[:en, :"en-US"], :formats=>[:html, :text, :js, :css, :ics, :csv, :vcf, :png, :jpeg, :gif, :bmp, :tiff, :mpeg, :xml, :rss, :atom, :yaml, :multipart_form, :url_encoded_form, :json, :pdf, :zip], :variants=>[], :handlers=>[:erb, :builder, :raw, :ruby]}. 
Searched in:
* "/Users/Jeremy/Projects/git/rails/app/views"

404 错误页面位于 views/errors/404.html.erb。从堆栈跟踪来看,它甚至看起来不像 Rails 正在访问 ErrorsController。 (代码和跟踪都在下面)

在开发模式下,我得到了标准的 Rails 错误页面,这是意料之中的。

application.rb

...
config.exceptions_app = self.routes
...

routes.rb

...

# Error pages
%w( 404 500 ).each do |code|
get code, :to => "errors#show", :code => code
end

...

errors_controller.rb

class ErrorsController < ApplicationController
def show
render status_code.to_s, :status => status_code
end
protected
def status_code
params[:code] || 500
end
end

堆栈跟踪似乎不是很有帮助:

Error during failsafe response: Missing template errors/show, application/show with {:locale=>[:en, :"en-US"], :formats=>[:html, :text, :js, :css, :ics, :csv, :vcf, :png, :jpeg, :gif, :bmp, :tiff, :mpeg, :xml, :rss, :atom, :yaml, :multipart_form, :url_encoded_form, :json, :pdf, :zip], :variants=>[], :handlers=>[:erb, :builder, :raw, :ruby]}.

最佳答案

尝试指定模板路径


def render_error(状态)
呈现状态:状态,模板:“错误/#{status}”
结尾
