我正在开发一个应用程序，我必须为路由组合一些自定义rails参数，当我尝试访问与no route found关联的页面时，我不断收到show错误方法。该应用程序允许我到达我的edit页面，所以我知道它在某种程度上工作，但我必须有一个错误，我没有看到某个地方正在弄乱普通视图。自定义参数依赖于为每个对象自定义创建的:identifier。因为应用程序管理多个机构，所有机构都有自己的对象和文件，所以我必须使用几组不同的路由来处理每个不同的事情。机构的路线似乎工作正常，但第二组，:intellectual_objects是不起作用的。
这是我的路线档案（不相关的部分除外）：
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
这是我的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------------------------------------------"

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

#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
当我尝试访问show路由时，我收到以下错误（例如：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"]}}
参数显示：
{"intellectual_object_identifier"=>"columbia.edu/798d6e812041532c"}
当我在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"}
我只是不明白，因为路由在那里，其中一些似乎在应用程序中工作，但每一个都在我的规范测试中失败。任何和所有的帮助表示赞赏。谢谢。
答案 0 :(得分：1)
您前往intellectual_objects#index的路线约束:institution_identifier应与/[\w+\.]+/匹配，但columbia.edu/798d6e812041532c与该正则表达不匹配。即使你向正则表达式添加\/，我也很确定斜杠会混淆Rails路由系统。
也许您想要将路线更改为此类
get "institutions/:institution_identifier/:some_id/objects",
to: 'intellectual_objects#index',
as: :institution_intellectual_objects,
constraints: { institution_identifier: /[\w+\.]+/ }
而不是将columbia.edu（institution_identifier）和798d6e812041532c（some_id）作为单独的值提供。
答案 1 :(得分：0)
根据你的错误：
No route matches {:action=>"index"
您似乎正在尝试访问index操作？
说实话，我无法通过你所有的路线（你可能想要删除无关的东西？）
您如何使用link_to来调用路线？
