如何更改Active Admin输入按钮的文本

Question

I have a form in my ActiveAdmin model and I need to translate the content of the button that is generated to upload a file.

I have the following form:

  form do |f|
    f.inputs 'Details' do
      f.input :orders_file, as: :file
    end
    actions
  end

Which displays this:

I would like to translate or change that 'Choose file' and 'No file chosen' texts.

I've tried with

input_html: { title: 'this', text: 'will', label: 'work', value: 'please' }

but no luck.

Thank you!

Answer 1

You can not change the file field default labels on buttons and text, they are hard-coded in browsers. Each Browser has its own way to render these things.

Only way to change these labels is, build your own custom file field control.

更改文件上传字段标签涉及迈克尔·麦格雷迪（Michael McGrady）发明的一些特殊技术，在https://www.quirksmode.org/dom/inputfile.html上进行了详细讨论。
