Hi. Recently I started rebuilding my old Mechanize script, which I
used to automatically log in to a certain site and retrieve files from
it. Old version worked great, however, when I did the update it
started complaining. Here''s the log of the error:
/Users/lukastolyarov/.gem/ruby/1.8/gems/mechanize-1.0.0/lib/mechanize/form/field.rb:30:in
`<=>'': undefined method `<=>'' for <input
type="hidden" name="next"
value="/blog/">:Nokogiri::XML::Element (NoMethodError)
from
/Users/lukastolyarov/.gem/ruby/1.8/gems/mechanize-1.0.0/lib/mechanize/form.rb:171:in
`sort''
from
/Users/lukastolyarov/.gem/ruby/1.8/gems/mechanize-1.0.0/lib/mechanize/form.rb:171:in
`build_query''
from
/Users/lukastolyarov/.gem/ruby/1.8/gems/mechanize-1.0.0/lib/mechanize/form.rb:221:in
`request_data''
from
/Users/lukastolyarov/.gem/ruby/1.8/gems/mechanize-1.0.0/lib/mechanize.rb:452:in
`post_form''
from
/Users/lukastolyarov/.gem/ruby/1.8/gems/mechanize-1.0.0/lib/mechanize.rb:370:in
`submit''
from downloader.rb:16:in `downloader''
from downloader.rb:38
Basically, what I''m doing is this:
require ''rubygems''
require ''mechanize''
agent = Mechanize.new
# create agent bject
page = agent.get(''www.mysite.com";)
#authenticate
form = page.forms.first
form.username = ''username''
form.password = ''password''
#submit form
page = agent.submit form
I think what''s causing the error is a hidden field that the form has
which looks like this:
<input type="hidden" name="next"
value="/blog/">
do you guys know how I can circumvent this issue?
Thanks!
Luka
I think you have to update nokogiri, too. On Thu, Jun 3, 2010 at 10:20 AM, Luka Stolyarov <lukich at gmail.com> wrote:> Hi.
