ActiveStorage::InvariableError 使用 Mini Magick

Question

<%= image_tag @supply.supply_photo.variant(resize: "400x400") %>

这是我的看法。 @supply.supply_photo 适用于未调整大小的原始图像。我的图像是一个 webp...我把它变成了一个具有相同结果的 jpg。我觉得我错过了一些简单的东西，但可以弄清楚我错过了什么。

我得到的错误是ActiveStorage::InvariableError

Answer 1

这解决了我的问题

<%= image_tag @supply.supply_photo.variant(resize_to_limit: [400, 400]) %>

Answer 2

在你的配置文件中 config/environments/production.rb 添加这一行

config.active_storage.variable_content_types = %w(image/png image/gif image/jpg image/jpeg image/webp)

并在 ubuntu 安装 webp 应用程序

sudo apt-get install webp

这对我有用
