ruby-on-rails - 如何播种图像的路径？

Question

Organization 和 Image 具有一对一的关系。 Image 有一个名为 filename 的列，它存储文件的路径。我在 Assets 管道中包含这样一个文件:app/assets/other/image.jpg。播种时如何包含此文件的路径？

我已经在我的种子文件中尝试过:

@organization = ...
@organization.image.create!(filename: File.open('app/assets/other/image.jpg'))
# I also tried:
# @organization.image.create!(filename: 'app/assets/other/image.jpg')

两者都产生错误:

NoMethodError: undefined method `create!' for nil:NilClass

我检查了调试器，可以确认不是 @organization 是 nil。
我怎样才能让它工作并将文件的路径添加到 Image 模型？

更新:我尝试了以下操作:

@image = Image.create!(organization_id: @organization.id,
                       filename: 'app/assets/other/image.jpg')

我也试过:

image = @organization.build_image(filename: 'app/assets/other/image.jpg')
image.save

播种后，两次尝试都会产生错误:

因为您的错误清楚地说明了问题所在。原来 @organization 还没有任何图像。所以试试

file  = File.open(File.join(Rails.root,'app/assets/other/image.jpg'))
image = @organization.build_image(filename: file)
image.save
