アプリケーションの設定を変更したいアプリケーションを実装しています。そうしている間、私はエラーが発生しています
no routes matches {:action=>"show", :controller=>"settings", format=>"nil"}
開いているnew settingsタブをクリックしている間。
私index.htmlは次のとおりです:-
<h1>Listing settings</h1>
<table class="table table-striped table-bordered">
<tr>
<th>ID</th>
<th>Name</th>
<th>Value</th>
<th>Description</th>
<th>Edit</th>
<th>Delete</th>
</tr>
<% @settings.each do |c| %>
<tr>
<td><%= c.id %> </td>
<td><%= c.name %> </td>
<td><%= c.value %> </td>
<td><%= c.description %> </td>
<td><%= link_to 'Edit', {:action => 'edit', :id => c.id} %> </td>
<td><%= link_to 'Delete', {:action => 'delete', :id => c.id},
:data => { :confirm => "Are you sure you want to delete this value?" } %></td>
</tr>
<% end %>
</table>
<br />
<%= link_to 'New Setting', {:action => 'new'} %>
私settings controllerは次のとおりです： -
class SettingsController < ApplicationController
# GET /setting
# GET /setting.json
def index
@settings = Setting.all
respond_to do |format|
format.html # index.html.erb
format.json { render json: @settings }
end
end
# GET /setting/1
# GET /setting/1.json
def show
@setting = Setting.find(params[:id])
respond_to do |format|
format.html # show.html.erb
format.json { render json: @setting }
end
end
# GET /setting/new
# GET /setting/new.json
def new
@setting = Setting.new
respond_to do |format|
format.html # new.html.erb
format.json { render json: @setting }
end
end
# GET /setting/1/edit
def edit
@setting = Setting.find(params[:id])
end
# POST /setting
# POST /setting.json
def create
@setting = Setting.new(params[:setting])
respond_to do |format|
if @setting.save
format.html { redirect_to @setting, notice: 'Setting was successfully created.' }
format.json { render json: @setting, status: :created, location: @setting }
else
format.html { render action: "new" }
format.json { render json: @setting.errors, status: :unprocessable_entity }
end
end
end
# PUT /setting/1
# PUT /setting/1.json
def update
@setting = Setting.find(params[:id])
respond_to do |format|
if @setting.update_attributes(params[:setting])
format.html { redirect_to @setting, notice: 'Setting was successfully updated.' }
format.json { head :no_content }
else
format.html { render action: "edit" }
format.json { render json: @setting.errors, status: :unprocessable_entity }
end
end
end
# DELETE /setting/1
# DELETE /setting/1.json
def delete
@setting = Setting.find(params[:id])
@setting.deleted = 1
@setting.save
respond_to do |format|
format.html { redirect_to settings_url }
format.json { render :json => { :success => true } }
end
end
end
私new.htmlは次のとおりです： -
<h1>New settings</h1>
<%= form_for @setting do |f| %>
<% if @setting.errors.any? %>
<div id="errorExplanation">
<h2><%= pluralize(@setting.errors.count, "error") %> prohibited this setting from being saved:</h2>
<ul>
<% @setting.errors.full_messages.each do |msg| %>
<li><%= msg %></li>
<% end %>
</ul>
</div>
<% end %>
Id: <%= f.text_field :id %><br>
Name: <%= f.text_field :name %><br>
Values: <%= f.text_field :value %><br>
Description: <%= f.text_field :description %><br>
<% end %>
<%= link_to 'Back', settings_path %>
私のroutes.rbは次のとおりです:-
Lms::Application.routes.draw do
resources :books do
member do
post 'add'
post 'remove'
end
collection do
get 'add'
get 'list' => "books#index"
post 'get_books'
get 'get_books'
end
end
resources :books
resources :book_transactions
resources :book_issues
resources :book_holds
resources :categories
resources :users
resources :admins
resources :library_locations
resources :lov_values
resources :loan_fines
resources :lov_names
resources :loans_fines do
member do
post 'add'
post 'remove'
end
collection do
get 'add'
get 'list'
post 'get_loans_fines'
get 'get_loans_fines'
end
end
resources :settings do
member do
post 'add'
post 'remove'
end
collection do
get 'add'
get 'list'
post 'get_settings'
get 'get_settings'
end
end
root :to => 'books#index'
match ':controller(/:action(/:id))(.:format)'
奇妙な部分は、アクションをクリックすると、newアクションに移動/リダイレクトされるshowことです..なぜこれが起こっているのか少し混乱しています..
誰かがこれで私を助けることができます..
