【问题讨论】：

该错误表明您在数组上调用verifications。我会说你应该检查你的@user 的值。如果您无法弄清楚，您应该发布您的 routes.rb 和完整的 users_controller，尤其是 paypal_verification 操作。

我编辑了我的帖子，我也在使用设计！！不确定这是否会改变事情？

【参考方案1】：

我认为您的错误可能来自您的 UsersController 中的 set_user 方法，即使您没有在上面显示。

你能不能把它改成：

class UsersController < ApplicationController
  before_action :set_user, except: [:index]

  ... your other actions here

  def paypal_verification
   @verification = @user.verifications.new
  end

  private
    def set_user
      @user = User.find(params[:id])
    end
end

在您的意见/用户/paypal_verification.html.erb 中，您可以：

<div>
    <h>Hello</h>
<%= form_for([@user, @verification]) do |f| %>
    <%= f.email_field :paypal_email, :class => 'form-control', :placeholder => "Paypal Email", id: 'Pemail' %>
<%= f.text_field :paypal_firstname, :class => 'form-control', :placeholder => "Paypal FirstName", id: 'PfirstName' %>
<%= f.text_field :paypal_lastname, :class => 'form-control', :placeholder => "Paypal LastName", id: 'PlastName' %>
<%= f.text_field :paypal_verified, :class => 'form-control', id: 'Pverified'%>

<%= f.submit "verify", class: "btn btn-primary" %>
<% end %>
</div>

让我知道这是否有效。
