延迟的作业不返回任何方法错误[]

Question

正在尝试使用延迟作业上载文件

def import
  @report = current_user.reports.create!(name: params[:report_name])
  @contact = @report.contacts.delay.import(params[:file], params[:info_type])
  flash[:success]= "Contacts importing, check back in 2-3 minutes"
  redirect_to contacts_url
end

返回：

undefined method `import' for []

当我尝试不使用关联时：

def import
  @report = current_user.reports.create!(name: params[:report_name])
  Contact.delay.import(params[:file], params[:info_type], @report.id)
  flash[:success]= "Contacts importing, check back in 2-3 minutes"
  redirect_to contacts_url
end

我得到了：

undefined method `name' for nil:NilClass

导入：

def self.import(file, info, report_id)
    CSV.foreach(file.path) do |row|
        input = row*""
        # input = hashy["input"]
        case info
        when "email"
            begin
                contact_hash = FullContact.person(email: input)
                if contact_hash.status = 200
                    Contact.create!(input: input, contact_hash: contact_hash.to_json, info_type: info, found: true, pending: false, report_id: report_id) 
                elsif contact_hash.status = 202
                    Contact.create!(input: input, contact_hash: contact_hash.to_json , info_type: info, found: true, pending: true, report_id: report_id) 
                end
            rescue FullContact::NotFound 
                Contact.create!(input: input, contact_hash: nil, info_type: info, found: false, report_id: report_id)
            rescue FullContact::Invalid
            end
        when "telephone"
            begin
            Contact.create!(input: input, contact_hash: FullContact.person(phone: input).to_json, info_type: info, report_id: report) 
            rescue FullContact::NotFound 
                Contact.create!(input: input, contact_hash: "Not Found", info_type: info, report_id: report)
            rescue FullContact::Invalid
            end
        end
    end
end

我也不应该说我使用的是gmaps，它默认将纬度、经度和gmaps4rails列设置为nil，直到联系人被保存到数据库中。这就是原因吗？

使用self.import。它将会工作，而不仅仅是import

def self.import
