Errors on redirect

[erizocosmico]

Hi,

I've been trying to get the errors of the previous action after a redirect (which I've seen it's possible according to lotus/controller code) but I can't. I've also been searching for examples on how to do this right but I found nothing.

I have this on my controller config:

cookies true
sessions :cookie, secret: "foo"

On my action after the redirect I have this:

def call(params)
  puts errors.inspect
end

The first time I submit my form everything is ok, I get the errors on the action after the redirect. But if I submit the form more times I get the same errors as the first time no matter what the input contents are.

I've also noticed that two cookies "rack.session" are set. One with the path "/" and one with the path "/foo" where /foo is the endpoint of the form action. Maybe it has something to do with that.

Hello @mvader Thanks for opening this ticket. Are you using this framework alone, or with lotusrb?

I'm using it with lotusrb.

@mvader Which kind of error do you get? Is this related to hanami/hanami#196 ? Can you please post the stack trace here? Thank you.

I don't get any error. It just doesn't work as expected. I've been able to reproduce even with the fix you mentioned in #196.

Just setup an application with cookies and the session like that:

cookies true
sessions :cookie, secret: ENV['WEB_SESSIONS_SECRET']

Once you've submitted a form with errors, on every other request the retrieved errors via the errors method are the same, no matter what the input parameters were.

As I said, two cookies are set, maybe that's the problem. I implemented the sessions and cookies myself using Rack::Session and it worked. With Rack::Session only one cookie was set.

New action:

module Web::Controllers::Foo
  class New
    include Web::Action

    def call(params)
      puts errors.inspect?
    end
  end
end

Create action:

module Web::Controllers::Foo
  class Create
    include Web::Action

    params do
      param :title, presence: true, size: 3..255
    end

    def call(params)
      if !params.valid?
          # foo
      else
         # foo
      end
    end
  end
end

Closing because I think it was fixed by #100
