Is there a way to submit ajax/json requests with simple_form for Rails

Question

With the standard Rails form_for, I was able to pass ajax requests though select and collection_select helpers as such:

<%= address.collection_select :cou         


        

Answer 1

It is better to write it like this:

= simple_form_for sample_result, url: reject_sample_result_path(sample_result), method: :post, remote: true, input_html: {multipart: true} do |f|

When you explicitly declare data-url it will still first do the default route calculation, which in my case failed because the default routes did not exist (and should not exist --since I am overruling the url). When you declare just url it will just take the given url instead.
