Question

在我的rails应用程序中，我有两个步骤的客户表单。在第一步中，客户输入他的详细信息和徽标以及pdf，然后在下一步中选择他喜欢的主题。

my customers_controller

  def new
  if current_user.admin?
  @customer = Customer.new
  @customer.additional_fields.build
  else
  redirect_to root_path, notice: 'You dont have admin permissions'
  end
 end

 def edit
if current_user.admin?
  @customer = Customer.find(params[:id])
else
  redirect_to root_path, notice: 'You dont have admin permissions'
end
end

  def theme_selector
 @customer_id = params[:customer_id]
 puts @customer_id
 end

 def create
 Rails.logger.debug "PARAMS:"
  params.each do |k,v|
  Rails.logger.debug "#{k}: #{v}"
end

if current_user.admin?
  @customer = Customer.new(customer_params)

  respond_to do |format|
    if @customer.save
      format.html do
        redirect_to @customer, notice: 'Customer was successfully created.'
      end
      format.json { render :show, status: :created, location: @customer }
    else
      format.html { render :new }
      format.json do
        render json: @customer.errors, status: :unprocessable_entity
      end
    end
  end
else
  redirect_to root_path, notice: 'You dont have admin permissions'
end
end

_form.html.erb

   <%= form_for @customer, url: theme_selector_path,:method => :post,html: { multipart: true } do |f| %>

  <input type="hidden" name="customer_id" value="<%= @customer.id %>">
 <% if @customer.errors.any? %>
 <div id="error_explanation">
   <h2>
    <%= "#{pluralize(@customer.errors.count, "error")} prohibited this customer from being saved:" %>
  </h2>
  <ul>
    <% @customer.errors.full_messages.each do |msg| %>
      <li>
        <%= msg %>
      </li>
    <% end %>
  </ul>
  </div>
 <% end %>
 <div class="form-group">
 <%= f.label :name %>
<%= f.text_field :name, class:"form-control" %>
</div>
<div class="form-group">
<%= f.label :address %>
<%= f.text_field :address, class:"form-control" %>
</div>
<div class="form-group">
<%= f.label :affiliate_id %>
<%= f.text_field :affiliate_id, class:"form-control" %>
</div>
<div class="control-group">
<%= f.label :logo, :class => 'control-label' %>
<div class="controls">
  <%= f.file_field :logo,accept: 'image/png,image/gif,image/jpeg, image/jpg' %>
 </div>
</div>
<div class="form-group">
<label>Upload File</label>
<%= f.file_field :file,accept: 'application/pdf' %>
</div>
<div class="form-group">
<% f.fields_for :additional_fields do | ing | %>
  <%= ing.text_field :key, :size => 50 %>
  <%= ing.text_field :value, :size => 50 %>
<% end %>
  </div>
  <div class="actions">
  <div class="row">
  <div class="col-md-5">

    <span><%= f.submit 'Save', class: "btn-addmore" %></span>
 <span><!--%= link_to 'Back', customers_path, class: "btn btn-danger" %-->    </span>
  </div>
  <div class="col-md-2 col-md-offset-4">
    <%= link_to "next", theme_selector_path, class: "btn-update" %>

  </div>
  </div>
 </div>
<% end %>

我在theme_selector.html.erb上有一个提交按钮来创建客户。但是我收到了一个错误＆＃34; Paperclip :: AdapterRegistry :: NoHandlerError（找不到＆＃34的处理程序;＃＆＃34; ）＆＃34;在客户控制器中创建行动。

提前致谢！

客户表单的第1步包含客户详细信息，第2步包含主题选择。但是，我能够在步骤1中上传和保存数据，但是在保存步骤1中的数据时遇到错误第2步一起在theme_selector页面。

customer.rb

    class Customer < ApplicationRecord


   has_attached_file  :logo
   validates_attachment_content_type :logo, :content_type => /\Aimage\/.*\Z/

   has_attached_file  :file
    validates_attachment_content_type :file, :content_type => "application/pdf" 

  end

无法使用paperclip gem上传图像
