Rails 5 - Preserve :js format while redirecting

I have a situation where:

  1. Browser submits a JS format request to the server.
  2. The server action redirects to another server action.
  3. The second action renders javascript in a .js.erb file.

Despite trying a number of approaches, Rails 5 renders the .js.erb literally, showing me the actual code in the view.

How can one get a Rails redirect_to to happen in JS format so the js.erb file is run properly?

In Rails 4.2, this works:

redirect_to custom_data_path(...), format: 'js'

In Rails 5.2, I've tried:

# 1
redirect_to custom_data_path(...), format: 'js'

# 2
redirect_to custom_data_path(...), format: :js

# 3
respond_to do |format|
  format.js { redirect_to custom_data_path(...) }
end

# 4
request.format = :js
respond_to do |format|
  format.js { redirect_to custom_data_path(...) }
end

I had the same problem where my format (json) was not preserved while redirecting

I solved it with (Rails 5):

redirect_to _path(, params: request.query_parameters.merge(format: params[:format]))

I don't think there's a concept or "redirect" for js requests. You can always render a script that does a request to the "redirected" url you want.

Instead of

format.js { redirect_to custom_data_path(...) }

You could have a view for that action with

//I'm using query just as an example, but it can be done with vanilla javascript o any js framework
$.getScript('<%= custom_data_path -%>');
