我无法在嵌套脚手架表单中上传图像。
除图像外，所有其他字段都将进入数据库。请帮忙！
我在轨道 5.2 上，使用回形针上传图像，图像需要上传到 AWS。
我没有收到任何错误，只是图像没有进入数据库。
谢谢！

在您的模型中，您有：
has_attached_file :image
所以我假设，每个内容都只附加了一个图像，但是在视图中的表单中，您将多个图像作为一个数组上传。
<%= f.file_field "images[]", type: :file, multiple: true %>
将其更改为：
<%= f.file_field :image %>
此外，在 ContentController 中，在content_params操作中，将 ：images 参数更改为 ：image
params.require(:content).permit(:post_copy, :is_facebook, :is_instagram, :is_twitter, :is_youtube, :price, :image)
但是，如果要附加多个图像，则必须完全更改方法。
要支持回形针上传到 s3，您需要将 gem "aws-sdk-s3" 添加到 Gemfile 文件中？并在模型中设置s3_credentials
class Content < ApplicationRecord
#
# rest of codes
###
has_attached_file :image, styles: { medium: "300x300>", thumb: "100x100>" } ,
