Rails simple_form: passing params on submit

Question

I'd like to pass custom params when user submits a form. I found this question but I still didn't get it to work.

These are my params on the form page: {"email"=>"[email protected]", "controller"=>"devise/passwords", "action"=>"new"}

Here's my form :

%h2 Forgot your password?
= simple_form_for(resource, as: resource_name, url: password_path(resource_name), html: { method: :post }) do |f|   =
f.error_notification   
.form-inputs
  = f.input :email, required: true, autofocus: true, input_html: { value: params[:email] }   
.form-actions
  = f.button :button, 'Submit', type: 'submit', name: 'email', value: params[:email]

Was this behaviour depreciated at some point or am I doing something wrong? I'm using ruby 2.5.1 and rails 5.2.

Just declare your after password reset path so that you can pass a param :

def after_sending_reset_password_instructions_path_for(resource_name) 
  my_path(email: resource.email)
end

This should work if your route to your successful password reset page is a collection path. If it is a member path, then just add resource like :

 def after_sending_reset_password_instructions_path_for(resource_name) 
   my_path(resource, email: resource.email)
 end

But I dont recommend using a member because it could leak data.
