如何设置我的 Rails 表单以提交到创建方法?

How do I set up my Rails form to submit to a create method?

我正在使用 Rails 5,但对如何设置表单以便它提交到我的 "create" 控制器方法感到困惑。这是我设置的路线

  resources :comments

这是我设置的表格

<%= form_for @comments, :html => {:class => "commentsForm"} do |f| %>
  <div class="field">
    <%= f.label :description %><br>
    <%= f.text_field :description %>
  </div>
  <%= recaptcha_tags %>
  <div class="actions">
    <%= f.submit %>
  </div>
<% end %>

但是上面的代码死于错误

undefined method `comments_index_path' for #<#<Class:0x00007fdaaf2b6240>:0x00007fdaaf2ae518>

我不确定我还应该做些什么才能让我的表格正常工作。在我的控制器中,我有一个 "create" 和一个 "new" 方法。

编辑:这是控制器

class CommentsController < ActionController::Base

  before_action :require_current_user, except: [:new]

  def new
    @comments = Comments.new
  end

  def create
    @comments = Comments.new(params[:comments].permit(:description))
    if verify_recaptcha(model: @comments)
      render "Finished"
    end
  end

end

我想,你的申请comments_controller新动作应该是这样的-

# app/controllers/comments_controller.rb 
class CommentsController < ApplicationController
 # Rest of code here

 def new
   @comment = Comment.new # Not the @comments
 end
 # Rest of code here
end

你的部分表格应该是这样的

# app/views/comments/_form.html.erb
<%= form_for @comment, :html => {:class => "commentsForm"} do |f| %>
  <div class="field">
    <%= f.label :description %><br>
    <%= f.text_field :description %>
  </div>
  <%= recaptcha_tags %>
 <div class="actions">
  <%= f.submit %>
  </div>
<% end %>
