"can't convert nil into Hash" when submitting a multipart form about capybara-webkit HOT 21 CLOSED

Are other people seeing this too when posting multipart forms? I'm curious if it's something specific to my setup which I could debug.

from capybara-webkit.

I got this area too today. Seems if the form does not have an attachment, it will bomb.

from capybara-webkit.

Got this as well...

from capybara-webkit.

Had a look at this one myself, we get an error, slightly different though:

Internal Server Error

bad content body
WEBrick/1.3.1 (Ruby/1.8.7/2011-02-18) at 127.0.0.1:56925

Looked through the webkit_server cpp code, and couldn't see where it might be a problem, thought maybe it was linkDelegationPolicy handling but no luck there.

from capybara-webkit.

Got the same error. Turns out that rack is raising:

EOFError: bad content body

right here: https://github.com/rack/rack/blob/master/lib/rack/request.rb#L182

unless @env["rack.request.form_hash"] = parse_multipart(env)

on the next request after submitting multipart form.

I'm having the same issue with same error as fxposter (bad content body). Any workarounds for this?

from capybara-webkit.

I have done this in my forms view code (HAML). A bit hacky, but it works.

:html => { :multipart => !Rails.env.test? }

from capybara-webkit.

Unfortunately that will not test the use of the form to submit attachments.

@metaskills this is definitely not an option.

from capybara-webkit.

Same problem here. Any hints to workarounds appreciated.

from capybara-webkit.

Any progress here? This is really the only thing holding us back on using this great gem.

I'd love to help out myself, but I have no idea how to go about debugging this.

from capybara-webkit.

Same here. The form gets submitted, but the redirect (the next GET request) fails with "Unable to load URL", if I turn off multipart forms, it works.

from capybara-webkit.

Getting the same issue as @excepttheweasel. Looking for a work-around... anyone have progress here?

WEBrick/1.3.1 (Ruby/1.9.2/2011-02-18) at 127.0.0.1:56993

from capybara-webkit.

This worked for me:

# config/environments/test.rb

class CapybaraWebkitFixer
  def initialize(app)
    @app = app
  end

  def call(env)
    if env['REQUEST_METHOD'] == "GET" && env['CONTENT_TYPE'] && env['CONTENT_TYPE'] =~ /^multipart/
      env['CONTENT_TYPE'] = nil
    end
    @app.call(env)
  end
end

+1 I'm getting the same error when submitting a multi-part form w/o any file attachments.

@ebeigarts: that hack fixes the behavior for me too. I have this problem with a Rails 3.1.0 app on ruby 1.9.2p312 (2011-08-11 revision 32926) [x86_64-darwin11.1.0].

A few debugging hints for capybara-webkit..

Show server debug output:
lib/capybara.rb in the gem: set Thin::Logging.silent = false in run_default_server to see this error.

Enable a lot of client debug output:
Use: Capybara.javascript_driver = :webkit_debug
instead of
Capybara.javascript_driver = :webkit

This shows the wire-protocol for the webkit driver, which may come in handy.

This has been fixed in #162

from capybara-webkit.

Works like a charm, thank you @ebeigarts! :)

When will this be available for a general "gem install"?

from capybara-webkit.

A new version of the gem with this fix would indeed be great.

from capybara-webkit.

A gem was released with this fix a while ago.
