Ruby on rails 找不到LeadsController#创建、呈现头部的模板：无内容

因此，我试图将一个联系我们表单发送到dropbox，目标是让用户创建一个带有上传文件字段（附件）的lead（联系我们表单），然后我会询问该用户是否希望成为客户irl，因此如果他成为客户，我希望他的lead中的附件（与他相关的联系我们表单）进入我的dropbox

这是我的联系我们控制器：

class LeadsController < ApplicationController
    require 'dropbox_api'
    skip_before_action :verify_authenticity_token
    def create
        @lead = Lead.new

        fullname = params['Name']
        company = params['Company']
        email = params['Email']
        phone = params['Phone']
        projectName = params['ProjectName']
        projectDescription = params['ProjectDescription']
        department_incharge = params['DepartmentInCharge']
        message = params['Message']
        attachment = params['attachment']


        @lead.full_name = fullname
        @lead.company_name = company
        @lead.email = email
        @lead.phone = phone
        @lead.project_name = projectName
        @lead.project_description = projectDescription
        @lead.department_in_charge = department_incharge
        @lead.message = message
        params_attach = attachment

        if params_attach
            @lead.attachment = params_attach.read
            @lead.original_filename = params_attach.original_filename


        client = DropboxApi::Client.new(ENV['DROPBOX_OAUTH_BEARER'])

        @lead.save!
        redirect_to root_path
        end
    end
 end

class LeadsController

这是我的客户模型：

class Customer < ApplicationRecord
    has_many :lead
    has_many :buildings
    belongs_to :address
    belongs_to :user

    after_update :dropbox

   self.all.each do |lead|
    def dropbox
       self.lead.all.each do |lead|
         if lead.attachment != nil
           client = DropboxApi::Client.new(ENV['DROPBOX_OAUTH_BEARER'])
           client.create_folder("/#{lead.full_name}")
           client.upload("/#{lead.full_name}/#{File.basename(lead.original_filename)}", lead.attachment)
             # lead.file_attachment = nil
             # lead.original_filename = nil
             # lead.save!
             end
           end
       end
   end
end

class客户

问题是，当我点击发送按钮确认我的报价时，它只是刷新页面（应该转到确认页面），在ubuntu控制台中，会出现以下情况：

找不到LeadsController#创建、呈现头部的模板：无内容 795ms内完成204无内容（ActiveRecord:0.0ms）

如果您需要更多信息，请告诉我，我真的被困在这一点上了

试试这个，将

重定向到
移出
如果
，添加flash消息以使其更清楚，我怀疑
参数附加
在这种情况下是
假
/
零

if params_attach
   @lead.attachment = params_attach.read
   @lead.original_filename = params_attach.original_filename


   client = DropboxApi::Client.new(ENV['DROPBOX_OAUTH_BEARER'])

   @lead.save!

end
redirect_to root_path

希望有帮助
 如果你没有附件怎么办？您应该将else块附加到if块。这可能是param_Attacht失踪的情况这很有效谢谢！
