正如标题所说，在运行我的本地主机应用程序时单击“登录”链接时出现以下错误：没有路由匹配 [GET]“/signin_path”
这是一些相关的文件/信息：
运行 rake 路由时：
users GET /users(.:format) users#index
POST /users(.:format) users#create
new_user GET /users/new(.:format) users#new
edit_user GET /users/:id/edit(.:format) users#edit
user GET /users/:id(.:format) users#show
PUT /users/:id(.:format) users#update
DELETE /users/:id(.:format) users#destroy
sessions POST /sessions(.:format) sessions#create
new_session GET /sessions/new(.:format) sessions#new
session DELETE /sessions/:id(.:format) sessions#destroy
signin /signin(.:format) sessions#new
signout DELETE /signout(.:format) sessions#destroy
root / static_pages#home
signup /signup(.:format) users#new
help /help(.:format) static_pages#help
about /about(.:format) static_pages#about
contact /contact(.:format) static_pages#contact
配置/路由文件：
SampleApp::Application.routes.draw do
resources :users
resources :sessions, only: [:new, :create, :destroy]
match '/signin', to: 'sessions#new'
match '/signout', to: 'sessions#destroy', via: :delete
root to: 'static_pages#home'
match '/signup', to: 'users#new'
match '/help', to: 'static_pages#help'
match '/about', to: 'static_pages#about'
match '/contact', to: 'static_pages#contact'
标题部分：
<header class="navbar navbar-fixed-top navar-inverse">
<div class="navbar-inner">
<div class="container">
<%= link_to "Sample App", root_path, id: "logo" %>
<nav>
<ul class="nav pull-right">
<li><%= link_to "Home", root_path %></li>
<li><%= link_to "Help", help_path %></li>
<% if signed_in? %>
<li><%= link_to "Users", '#' %></li>
<li id="fat-menu" class="dropdown">
<a href="#" class="dropdown-toggle" data-toggle="dropdown">
Account <b class="caret"></b>
</a>
<ul class="dropdown-menu">
<li><%= link_to "Profile", current_user %></li>
<li><%= link_to "Settings", '#' %></li>
<li class="divider"></li>
<li>
<%= link_to "Sign out", signout_path, method: "delete" %>
</li>
</ul>
</li>
<% else %>
<li><%= link_to "Sign In", 'signin_path' %></li>
<% end %>
</ul>
</nav>
</div>
</div>
</header>
最后是 sessesion_controller 文件：
类 SessionsController < ApplicationController
def new
end
def create
user = User.find_by_email(params[:session][:email].downcase)
if user && user.authenticate(params[:session][:password])
sign_in user
redirect_to user
else
flash.now[:error] = 'Invalid email/password combination'
render 'new'
end
end
def destroy
end
end
