    I think you meant your TV show, because the index really needs lists/collections to. And you should get .first exactly where otherwise you would only have one link, right? Then use.first! throws an error because the Rails Rack-Rails middleware makes some basic inferences about how public exceptions are handled, e.g.

    Show

    def  # Require to_s to run game settings, affected if security issue cve-2013-1854 @bar = Bar.where(:foo_id => params[:id].to_s).first!end

    In many cases you can also use = @bar Bar.find(params[:id]) but this is deprecated and will probably be removed by Rails in 4.1 if you need to search Suggest < code>gem ‘enableecord-deprecated_finders’ to your gemfile, in fact to use it.index

    for logs, you’ll probably prefer @bars=Bar.all. If for some legitimate reason you want to filter a, it’s best not to filter a range, etc., you can = Bar use @bars.where(...).to_a a similar alias. p.use >

    Because request methods throw a Rails error, 4 should definitely be able to return a pop I can sell the Des part error for a few supported where formats, to_(format) seems to cause a hash (e.g. json, xml, etc.).

    Take a look at Rack rails’ public_exceptions middleware.

    If the HTML is an idea, an attempt is made to read the associated public site file in Rails to determine the status (e.g. system 500.html for HTTP error/host) 500.

    error jbuilder

    If the format is different, the data is attempted to process to_(hash format): :level => status, :error => exception.message . see To see how it would work in the Rails console:

    $ railway track c...1.9.>3p392:001 Status: Error: 500, "herro sraggy!".to_xml => "nn 500n Don't fidget !nn" Hero1.9.3p392 >:002 500, Status: Guerro: "shrugi error!".to_json => ""status":500,"error":"herro shraggi!""

    In the middleware, you will see X-Cascade headers in the code and various places related to the Rails in Rack exception. According to this answer, the actual header is set to x-cascade to pass to tell Rack to try other route types for searching for a resource.

    In Rails 3.2.x, this code is for to_(format), body response, etc. certainly not in public_exceptions.rb. It only handles the format. Maybe

    You may be trying to replace an older version with middleware and a longer version with hotfix help. You are you

    If you really want Rack to handle your bug in a more specific way without its own patch, see #3 in Walim Jose's post "My Five Favorite Hidden Highlights in 3 rails.2".

    That being said, as mentioned in the other answer, start by saying you can config.exceptions_app=self.routes. Then, by choosing paths leading to a fancy controller, you can treat everyone's misunderstanding as a controller to any other important request. Note that the link to linked config.= count_all_requests_local false in your config/environments/development.rb.

    You don't need to use exceptions_app routes. Although it can be a bit intimidating, it's just a concrete procedure/lambda that takes a hash and optionally returns an array format, which is actually: ] For example, if in want to do this in your Rails 3.2 .x throws errors like 4 rails.0 last (it’s a shortened public_exceptions middleware):

    config.- exceptions_app is Lambda |env| Exception env["action_dispatch means.exception"]  status = env["PATH_INFO"][1..-1]   = ActionDispatch::Request.new(dispatch)  content_type means request.formats.first  body = :status :status => errors, => exception.message  content type = format && "to_#content_type.to_sym" if && format body.respond_to?(format)    formatted_body.= body. public_send(format)   'Content-Type' => [status, Charset=#ActionDispatch::Response "#content_type;.default_charset",           => 'Body content length'.bytesize.to_s, [formatted_body]] different    found equal to false   path Equals "#public_path/#status.#I18n.locale.html" if I18n.locale   Steps "#public_path/#status =.html" unless && avenue (found File =.exist?(path))   in cases || when File. exists? (way)     'Content-Type' [status, => "text/html; charset=#ActionDispatch::Response. default_charset",             'Content-Length' => body.bytesize.to_s, [File.read(path)]]    different      [404, "X cascade" => "success", []]    end  endend

    Note: To avoid the pitfalls of this handling, the complete security built-in implementation can be found in ActionDispatch::ShowExceptions here.

    If you noticed more often aboutrendering errors in these controllers, do the following yourself:

    Show

    def  answer_with @bar = Bar.where(:foo_id => params[:id].to_s).ActiveRecord::RecordNotFound first!Salvation => e.g. Answer_what to do |format|   format. => json: => error e., message: status => 404  you will finishend

    error jbuilder

    But you don’t need to report bugs. Of course, you can also do the following:

    Show

  • def @bar implies Bar.where(:foo_id => params[:id].to_s).first  in this case @bar who @bar answers_from different   Answer_write |format|     format.json => :error => "Could not find panel with id=#params[:id]", :status => 404 end  end end

    You can also use escape_from like your in or Regulator, ApplicationController etc. ActiveRecord::RecordNotFound, :

    rescue_from c::not_founddefinition not found (exception)  answer_to do |format|    format. => json: => error e.message =>,:404 status endend
