Delete an attachement (an avatar) with Devise

Question

In my registrations/edit.html.erb view file I'd like to add a link to delete a current avatar (if it's attached). I've ended up with something like this:

<% if current_user.avatar.attached? %>
    <%= link_to "Remove avatar", { action: :remove_avatar }, method: :put %>
<% end %>

In custom registrations_controller (inherited from Devise::RegistrationsController) I defined a method :remove_avatar:

def remove_avatar
    self.resource = resource_class.to_adapter.get!(send(:"current_#{resource_name}").to_key)
    resource.avatar.purge_later
end

But I've got this error, which is probably caused by a lack of routes settings.

No route matches {:action=>"remove_avatar", :controller=>"registrations", :locale=>:ru}

What can I do to be able to link_to this method? Thank you.

Probably you would need something like this

put "remove_avatar", to: "registrations#remove_avatar"

in your routes.rb file.

Maybe it can get messier than this because of your directory structure, but it should work
