ActiveStorage::IntegrityError Rspec附加文件

Question

我有一个用于创建虚拟数据的工厂，工厂名称是migration_session。

因此，我通过调用

创建了该工厂的一个实例

@loan_migration = create(:migration_session, :loan, cooperative: @cooperative, management: @manager)

这是我的migration_session工厂代码

FactoryBot.define do
factory :migration_session, class: Migration::Session do
cooperative
management
trait :loan do
excel_file { Rack::Test::UploadedFile.new("#{Rails.root}/public/payment_migration.xlsx", 'application/vnd.openxmlformats-officedocument.spreadsheetml.sheet') }
end

这是我的migration_session模型

class Migration::Session < ApplicationRecord
self.table_name = "migration_sessions"
has_one_attached :excel_file
end

因为我调用trait loan，它将通过excel文件payment_migration.xlsx附加excel_file属性。但是在尝试保存实例

之后出现这样的错误

ActiveStorage::IntegrityError:

如何解决这个问题?我的文件很好，我可以打开并编辑它。

我想你的问题在文件路径

excel_file { Rack::Test::UploadedFile.new("#{Rails.root}/public/payment_migration.xlsx", 'application/vnd.openxmlformats-officedocument.spreadsheetml.sheet') }

根据你的SO， '/'字符可能不允许在path上，所以不要传递路径字符串，让rails为你填充它。

使用Rails.root.join方法，像这样:Rails.root.join('public', 'payment_migration.xlsx')
