基于Ajax POST请求的Rails 404，尽管定义了路由
基于Ajax POST请求的Rails 404，尽管定义了路由
提问于 2019-09-30 02:16:04
我正在运行：
Rails 6 Ruby 2.5 Postgres 11.5 Mac OSX
我定义了以下路由：
Rails.application.routes.draw do
get 'welcome/index'
# For details on the DSL available within this file, see https://guides.rubyonrails.org/routing.html
root 'welcome#index'
post 'search_controller/search'
end我的视图中有以下代码：
<%= form_for :search, :url => url_for(:controller => 'search_controller', :action => 'search'), remote: true do |f| %>
<%= f.text_field :search_term %>
<%= f.submit %>生成的表单代码为：
<form action="/search_controller/search" accept-charset="UTF-8" data-remote="true" method="post">
<input type="text" name="search[search_term]" id="search_search_term">
<input type="submit" name="commit" value="Save Search" data-disable-with="Save Search">
</form>在我看来，这是我所期望的。我还尝试了一个rails 6样式的表单，如下所示：
<%= form_with(url: "/search_controller/search", method: "post") do %>
<%= label_tag(:q, "Search for:") %>
<%= text_field_tag(:term) %>
<%= submit_tag("Search") %>这也导致了同样的问题。
当我单击该按钮时，我得到一个HTTP 404响应：
rails-ujs.js:215 POST http://localhost:40250/search_controller/search 404 (Not Found)当我运行rails routes时，我得到：

update_rails_disk_service PUT /rails/active_storage/disk/:encoded_token(.:format) 请注意，您可以在search_controller_search上查看路由。
考虑到这些细节，为什么我会得到404？

问题出在路由定义中。
解决方案是改变：
post 'search_controller/search'至：
post 'search_controller/search', to:"search#search"页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
