Rails：为什么在用户提交表单之前发送电子邮件？答案

【问题标题】：Rails: why emails are sent before Users submit the form?Rails：为什么在用户提交表单之前发送电子邮件？

【问题描述】：

我有一个向客户发送价目表的“静态表单”，我需要发送一封电子邮件，但表单中的 params[:pricelist_name] 为 nil。

我注意到电子邮件是在视图之前发送的，所以我想知道如何仅在用户提交表单之后发送电子邮件？

干杯，

控制器

  def sendpricelist
    @pricelist = params[:pricelist_name] || []
    @request_id = params["pricelist_name"] || []
    @test = "test"
    SaasMailer.pricelist_request_email(@pricelist, @test, @request_id).deliver_now
    #redirect_to :requests
end

查看

    <%= form_tag(:controller => "requests", :action => "sendpricelist") do %>
  <%= text_field(:post, :title, size: 69, class: 'form-control form-group-lg') %>


<%= select_tag 'pricelist_name', 
  options_from_collection_for_select(Pricelist.all, :id, :name) %>


    <%= submit_tag("Send pricelist")%>



<% end %>

路线

 devise_for :users
 resources :users
 resources :requests do
 resources :updates
match '/sendpricelist',      to: 'requests#sendpricelist',           via: 'get'

end

输出：

正如您在“主题：[] - [] - 测试”中看到的那样，参数为零。

【问题讨论】：

在你的视图中试试这个：<%= form_tag sendpricelist_path do %> (source)
@NoamHacker 在我提交表单之前仍会发送电子邮件。干杯。
ActionController::RoutingError (没有路由匹配 [GET] "/requests/12/sendpricelist"):

标签： ruby-on-rails forms email controller routes

【解决方案1】：

我将路线更改为match '/sendpricelist', to: 'requests#sendpricelist', :via => [:get, :post]`
