向回形针gem添加自定义“样式”

Question

Right now I have this

has_attached_file :cover_image,
                   styles: { square: "200x200#", small:"400x400>",medium:"500x600" }

I want to have this:

has_attached_file :cover_image,
                   styles: { thumb: "50x50#", square: "200x200#", small: "400x400>", medium: "500x600" }

When I add the "thumb" key I get a 404 error. Is there a way to create a new "style"?

Answer 1

Seems like there is no issue in your code.

You might be getting error while fetching previous record's thumb, which is not generated yet. Try create previous record thumbnail also and your error will gone.

Run below command in console.

rake paperclip:refresh CLASS=User ## change User with model name.
