自定义rails参数中未找到路线错误

Question

I'm working on an application where I've had to put together some custom rails parameters for the routes and I keep getting no route found errors when I try to access the page associated with the show method. The application is allowing me to reach my edit pages, so I know it's working on some level but I have to have an error I'm not seeing somewhere that's messing with the normal view. The custom parameters rely on an :identifier that has been custom created for each object. Because the application manages several institutions, all with their objects and files, I've had to right several different sets of routes to handle each different thing. The routes for institutions seem to be working fine, but the second set, for :intellectual_objects are the ones that aren't working.

This is my routes file (irrelevant parts excluded):

Fluctus::Application.routes.draw do

  get "institutions/:institution_identifier/objects", to: 'intellectual_objects#index', as: :institution_intellectual_objects, :constraints => { :institution_identifier => /[\w+\.]+/ }
  post "institutions/:institution_identifier/objects", to: 'intellectual_objects#create', :constraints => { :institution_identifier => /[\w+\.]+/ }

  #Intellectual Object Routes
  #get "objects/:institution_identifier", to: 'intellectual_objects#index', as: :institution_intellectual_objects, :constraints => { :institution_identifier => /[\w+\.]+/ }
  #post "objects/:institution_identifier", to: 'intellectual_objects#create', :constraints => { :institution_identifier => /[\w+\.]+/ }

  patch "objects/:intellectual_object_identifier", to: 'intellectual_objects#update', :constraints => { :intellectual_object_identifier => /[\w+\/\.]+/ }
  put "objects/:intellectual_object_identifier", to: 'intellectual_objects#update', :constraints => { :intellectual_object_identifier => /[\w+\/\.]+/ }
  delete "objects/:intellectual_object_identifier", to: 'intellectual_objects#destroy', :constraints => { :intellectual_object_identifier => /[\w+\/\.]+/ }
  get "objects/:intellectual_object_identifier/edit", to: 'intellectual_objects#edit', as: :edit_intellectual_object, :constraints => { :intellectual_object_identifier => /[\w+\/\.]+/ }
  get "objects/:intellectual_object_identifier/events", to: 'events#index', as: :intellectual_object_events, :constraints => { :intellectual_object_identifier => /[\w+\/\.]+/ }
  post "objects/:intellectual_object_identifier/events", to: 'events#create', :constraints => { :intellectual_object_identifier => /[\w+\/\.]+/ }
  get "objects/:intellectual_object_identifier", to: 'intellectual_objects#show', as: :intellectual_object, :constraints => { :intellectual_object_identifier => /[\w+\/\.]+/ }

  #post "objects/institution_identifier/:intellectual_object_identifier/data", to: 'generic_files#create', as: intellectual_object_generic_files, :constraints => { [:intellectual_object_identifier, :institution_identifier] => /[\w+\.]/ }
  #patch "objects/institution_identifier/:intellectual_object_identifier/data/:filename", to: 'generic_files#update', :constraints => { [:intellectual_object_identifier, :institution_identifier] => /[\w+\.]/ }

  Blacklight.add_routes(self)

  mount Hydra::RoleManagement::Engine => '/'

  root :to => "catalog#index"
end

This is my IntellectualObject Controller:

class IntellectualObjectsController < ApplicationController
  before_filter :authenticate_user!
  #load_and_authorize_resource :institution, only: [:index, :create]
  load_and_authorize_resource :through => :institution, only: :create
  #load_and_authorize_resource except: [:index, :create]
  before_filter :set_object, only: [:show, :edit, :update, :destroy]
  before_filter :set_institution, only: [:index, :create]

  include Aptrust::GatedSearch
  apply_catalog_search_params
  include RecordsControllerBehavior

  self.solr_search_params_logic += [:for_selected_institution]

  def update
    if params[:counter]
      # They are just updating the search counter
      search_session[:counter] = params[:counter]
      redirect_to :action => "show", :status => 303
    else
      # They are updating a record. Use the method defined in RecordsControllerBehavior
      super
    end
  end

  def destroy
    resource.soft_delete
    respond_to do |format|
      format.json { head :no_content }
      format.html {
        flash[:notice] = "Delete job has been queued for object: #{resource.title}"
        redirect_to root_path
      }
    end
  end

  protected 

  # Override Hydra-editor to redirect to an alternate location after create
  def redirect_after_update
    intellectual_object_path(resource)
  end

  def self.cancan_resource_class
    CanCan::ControllerResource
  end

  private

  def for_selected_institution(solr_parameters, user_parameters)
    #puts "In for_selected_institution------------------------------------------"
    #puts params[:institution_identifier]
    #puts params[:intellectual_object_identifier]
    if(params[:institution_identifier])
      institution = Institution.where(desc_metadata__institution_identifier_tesim: params[:institution_identifier]).first
    else
      io = IntellectualObject.where(desc_metadata__intellectual_object_identifier_tesim: params[:intellectual_object_identifier]).first
      institution = io.institution
    end
    #puts "INSTITUTION: #{institution.id}"
    solr_parameters[:fq] ||= []
    solr_parameters[:fq] << ActiveFedora::SolrService.construct_query_for_rel(is_part_of: "info:fedora/#{institution.id}")
  end

  # Override Blacklight so that it has the "institution_identifier" set even when we're on a show page (e.g. /objects/foo:123)
   def search_action_url options = {}
    institution_intellectual_objects_path(params[:institution_identifier] || @intellectual_object.institution.institution_identifier)
  end

  def set_institution
    if params[:institution_identifier].nil? || Institution.where(desc_metadata__institution_identifier_tesim: params[:institution_identifier]).empty?
      redirect_to root_url
      flash[:alert] = "Sonething wrong with institution_identifier."
    else
      @institution = Institution.where(desc_metadata__institution_identifier_tesim: params[:institution_identifier]).first
      authorize! [:create, :index], @institution if cannot? :read, @institution
    end
  end

  def set_object
    if params[:intellectual_object_identifier].nil? || IntellectualObject.where(desc_metadata__intellectual_object_identifier_tesim: params[:intellectual_object_identifier]).empty?
      redirect_to root_url
      flash[:alert] = "Something wrong with intellectual_object_identifier."
    else
      io_options = IntellectualObject.where(desc_metadata__intellectual_object_identifier_tesim: params[:intellectual_object_identifier])
      io_options.each do |io|
        if params[:intellectual_object_identifier] == io.intellectual_object_identifier
          @intellectual_object = io
          @institution = @intellectual_object.institution
        end
      end
      if @intellectual_object.nil?
        redirect_to root_url
        flash[:alert] = "The object you requested does not exist."
      end
      #authorize! [:show, :edit, :update, :destroy], @institution if cannot? :read, @institution
    end
  end
end

I'm getting the following error when I try to access the show route (for example: localhost:3000/objects/test.org/126939282):

ActionController::UrlGenerationError in IntellectualObjects#show
Showing /Users/kec6en/HydraApp/fluctus/app/views/intellectual_objects/_facet_limit.html.erb where line #11 raised:

No route matches {:action=>"index", :intellectual_object_identifier=>"columbia.edu/798d6e812041532c", :controller=>"intellectual_objects", :f=>{"institution_name_ssi"=>["Columbia University"]}}

The parameters are showing:

{"intellectual_object_identifier"=>"columbia.edu/798d6e812041532c"}

And I'm getting this error when I run my spec tests on the IntellectualObjectController

Failure/Error: get :show, intellectual_object_identifier: obj1
ActionController::UrlGenerationError:
   No route matches {:intellectual_object_identifier=>"kaulkedurgan.org13/39b1eb47-da8b-4145-b03b-5f1851407012", :controller=>"intellectual_objects", :action=>"show"}

I just don't understand because the routes are there, and some of them appear to be working in the application, but every single one is failing in my spec tests. Any and all help is appreciated. Thank you.

Answer 1

Your route to intellectual_objects#index has the constraint that the :institution_identifier should match /[\\w+\\.]+/ , but columbia.edu/798d6e812041532c does not match that regexp. Even when you add \\/ to your regexp, I am pretty sure that the slash will confuse Rails routing system.

Perhaps you want to change the route to something like this

get "institutions/:institution_identifier/:some_id/objects", 
    to: 'intellectual_objects#index', 
    as: :institution_intellectual_objects, 
    constraints: { institution_identifier: /[\w+\.]+/ }

And than provide columbia.edu (institution_identifier) and 798d6e812041532c (some_id) as separate values.

Answer 2

According to your error:

No route matches {:action=>"index"

It seems you're trying to access the index action?

Being honest, I couldn't bring myself to look through all your routes (you may want to cut out the irrelevant stuff?)

How are you calling the routes with link_to ?
