html - 用户中的 NoMethodError#paypal_verification

Question

我收到这个错误加载页面时出现此错误。为什么会这样？这跟用户有关系吗？？我的网址是 http://localhost:3000/users/4/paypal_verification

错误日志:

ActionView::Template::Error (undefined method `verifications' for #<Array:0x007ffc8e78f590>):
    1: <%= form_for([@user, @user.verifications.new]) do |f| %>
    2: 	<%= f.email_field :paypal_email, :class => 'form-control', :placeholder => "Paypal Email", id: 'Pemail' %>
    3: <%= f.text_field :paypal_firstname, :class => 'form-control', :placeholder => "Paypal FirstName", id: 'PfirstName' %>

用户 Controller

def index

        @search = User.ransack(params[:q])
        @user = @search.result.order("created_at DESC").to_a.uniq

        @country = User.uniq.pluck(:country)
        @city = User.uniq.pluck(:city)
        @school = User.uniq.pluck(:school)
        @major = User.uniq.pluck(:major)


        @results = @search.result
        @arrUsers = @results.to_a

        @revisers = Reviser.all

    end

def paypal_verification

    @user.find(params[:user_id])
end



    def show
        @user = User.find(params[:id])
        @users = User.all
        @revisers = Reviser.all


    end

验证 Controller

def create
    @user = User.find(params[:user_id])
    @verification = current_user.verifications.create(verification_params)
    redirect_to @user.edit

    if @verification 

            require 'paypal-sdk-adaptiveaccounts'
@api = PayPal::SDK::AdaptiveAccounts::API.new( :device_ipaddress => "127.0.0.1" )

# Build request object
@get_verified_status = @api.build_get_verified_status({
  :emailAddress => "<%= current_user.paypal_email %>",
  :matchCriteria => "NAME",
  :firstName => "<%= current_user.paypal_firstname %>",
  :lastName => "<%= current_user.paypal_lastname %>" })

# Make API call & get response
@get_verified_status_response = @api.get_verified_status(@get_verified_status)

# Access Response
if @get_verified_status_response.success?
  @get_verified_status_response.accountStatus
  @get_verified_status_response.countryCode
  @get_verified_status_response.userInfo
else
  @get_verified_status_response.error
end

      params.permit!
    status = params[:accountStatus]

verification = Verification.find(params[:paypal_email])

if status == "VERIFIED"
    verification.update_attributes paypal_verified: true
else 
    verification.update_attributes paypal_verified: false
    verification.destroy
end
else
    redirect_to @user.edit
end
    end



    private

我认为你的错误可能来自 UsersController 中的 set_user 方法，即使你没有在上面显示它。

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 views/users/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>

如果可行，请告诉我。
