Situation
I am using the very common gem simple_form for my forms in my german rails app. I want to localize my file uploads on all of my models.

My problem:
Now it shows in english “Choose File” on the button and “No file chosen” based on the lack of I18n input (see below).

I have no clue on how to change this behaviour. What exactly to chanege in the YML file? Which key? What to insert in below YML file?

From the docs I created a simple_form.de.yml file which reads:

de:
  simple_form:
    ...standard stuff...
