如何播种图像路径? [英] How to seed the path to an image?

问题描述

Organization和Image具有1-to-1 relationship. Image有一个称为filename的列，该列存储文件的路径.我在资产管道中包含这样的文件:app/assets/other/image.jpg.播种时如何包含此文件的路径?

Organization and Image have a 1-to-1 relationship. Image has a column called filename, which stores the path to a file. I have such a file included in the asset pipeling: app/assets/other/image.jpg. How can I include the path to this file when seeding?

我在种子文件中尝试过

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

两者都会产生错误:

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

我检查了debugger并可以确认不是 @organization是零.
如何进行这项工作并将文件的路径添加到Image模型?

I checked with the debugger and can confirm that it's not @organization that is nil.
How can I make this work and add the path to the file to the Image model?

更新:我尝试了以下操作:

Update: I tried the following:

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

我也尝试过:

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

播种后两次尝试均产生错误:

Upon seeding both attempts produce the error:

CarrierWave::FormNotMultipart: You tried to assign a String or a Pathname to an uploader, for security reasons, this is not allowed.

推荐答案

由于您的错误清楚地说明了问题所在.事实证明@organization还没有任何图像.所以尝试

As your error is clearly telling what the issue is. It turns out that @organization doesn't have any image yet. So try

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