没有与 [GET] "/accounts.json"匹配的路由

Question

我正在尝试为用户提供创建子域的能力。单击"创建帐户"时，系统会从"帐户/新"重定向到"帐户"，并且不会填充任何子域。

路线.rb

class SubdomainPresent
  def self.matches?(request)
    request.subdomain.present?
  end
end
class SubdomainBlank
  def self.matches?(request)
    request.subdomain.blank?
  end
end
Saasapp::Application.routes.draw do
  constraints(SubdomainPresent) do
    root 'projects#index', as: :subdomain_root
    devise_for :users, controllers: { registrations: 'users/registrations' } 
    resources :users, only: :index
    resources :projects, except: [:index, :show, :destroy]
  end
  constraints(SubdomainBlank) do
    root 'visitors#new'
    resources :accounts, only: [:new, :create]
  end
end

accounts_controller.rb

class AccountsController < ApplicationController
  skip_before_action :authenticate_user!, only: [:new, :create]

  def new
    @account = Account.new
  end
  def create
    @account = Account.new(account_params)
    if @account.valid?
      Apartment::Database.create(@account.subdomain)
      Apartment::Database.switch(@account.subdomain)
      @account.save
      redirect_to new_user_session_url(subdomain: @account.subdomain)
    else
      render action: 'new'
    end
  end

新.html.erb

 <%= simple_form_for @account do |f| %>
    <%= f.input :subdomain do %>
      <div class="input-group">
        <%= f.input_field :subdomain, class: 'form-control' %>
        <span class="input-group-addon">.demo.dev</span>
      </div>
    <% end %>
    <%= f.button :submit, class: 'btn-primary' %>
  <% end %>

ActionController::RoutingError (No route matches [GET] "/accounts.json"):

Answer 1

这一行：

resources :accounts, only: [:new, :create]

告诉Rails"只为一个帐户设置new和create路由"。

它基本上说"不要设置索引路由">

如果您想要一个索引路由(即将显示所有帐户的列表(，那么您需要将该行更新为例如：

resources :accounts, only: [:new, :create, :index]

Answer 2

将 ：index 路由添加到行： 资源 ：帐户，仅：[：新建，：创建]在帐户控制器中创建索引操作和句柄 渲染 json：您的对象
