to_param with ".html" fails to edit

[Olli]

Hi,
in my models I have a to_param which builds me something like "#{urlalias}.html" (for legacy reasons). If I want to edit this resource I got an error that the route can't be found.
Is there any way to handle this problem?

Hi @Olli

Unfortunately we didn't found a solution for this issue yet

There is a opened issue around this, let's continue the discussion there #3368

Well maybe "get "/avo/resources/:resource/:id.html/edit", to: redirect("/avo/resources/%{resource}/%{id}/edit")" should resolve this issue at least on my side. Unfortunately it took some hours for me to find this solution thou it's so easy.

Hmm interesting, can you share a snippet with an example please?

[Olli]

Im not entirely sure what snippet you like but here is my routes.rb configuration

  authenticate :user do
    get "/avo/resources/:resource/:id.html/edit", to: redirect("/avo/resources/%{resource}/%{id}/edit")
    mount Avo::Engine, at: Avo.configuration.root_path
  end

in my model I have

to_param
  "#{urlalias}.html"
end

I should mention, that the redirect doesn't work if the urlalias contains a German "ß". I'm not sure why but tbh I don't understand the Rails routing code. In theory "ß" shouldn't be a problem.
If the "ß" is in the url alias the ":id" can't be recognized and the route can't be found.

so /avo/resources/my-resource/resourcealias.html/edit is redirected to /avo/resources/my-resource/resourcealias/edit

Thanks for sharing this @Olli!!
