Ruby on rails Rails中奇怪的路由行为
我使用的是rails 4.2。我已经创建了一个表单，该表单提交给控制器中的特定操作。以下是表单代码和控制器定义的开头： view.html.erbRuby on rails Rails中奇怪的路由行为,ruby-on-rails,ruby,ruby-on-rails-4,Ruby On Rails,Ruby,Ruby On Rails 4,我使用的是rails 4.2。我已经创建了一个表单，该表单提交给控制器中的特定操作。以下是表单代码和控制器定义的开头： view.html.erb <div id="account-booking" class="tab-pane"> <%= form_for @booking_info, url: { action: 'book' } do |b| %> <fieldset class="group column-1"> &l

这毫无意义。我的观点完全相同。我只是使用了所有这些代码来创建记录，因此路由显然存在（因为它调用/account/book）。现在我想更新，但突然路线不匹配？而且它甚至从不进入代码，因为它不调用控制器操作。这对我来说毫无意义。希望有人能帮忙。我发现了问题。这真是太愚蠢了。我的route.config中有以下行：
match ':controller(/:action(/:id))', :via => [:get, :post]
match ':controller(/:action(/:id))', :via => [:get, :post, :patch, :put, :delete]
现在它处理更新（即修补/放置）我发现了问题。这真是太愚蠢了。我的route.config中有以下行：
match ':controller(/:action(/:id))', :via => [:get, :post]
match ':controller(/:action(/:id))', :via => [:get, :post, :patch, :put, :delete]
现在，它可以处理更新（即修补/放置）当我查看您的代码时，我感到有些畏缩，下面是我应该如何做的：
