I can run this code just fine in irb, but when I run it in rails
script/console, I get an error:
>> res = agent.submit(search_form, search_form.buttons.first)
ArgumentError: one hash required

Here''s the code:
#!/usr/local/bin/ruby
require ''rubygems''
require ''mechanize''
require ''logger''
require ''uri''
require ''net/http''
agent = WWW::Mechanize.new { |a| a.log = Logger.new("mech.log") }
agent.user_agent_alias = ''Mac Safari''
page =
agent.get(''http://www.fyi.legis.state.tx.us/Address.aspx'')
search_form = page.form_with(:name => "AddressForm")
search_form.field_with(:name => "Address1").value = "501 W
26th St,
Apt 110"
search_form.field_with(:name => "City").value = "Austin"
search_form.field_with(:name => "ZipCode").value =
"78705"
search_form.field_with(:name => "DistrictType").options[0].select
res = agent.submit(search_form, search_form.buttons.first)
It should return a Mechanize page object.
And no, that''s no longer my address.
What is this interpolation core extension? Why is that causing a
problem? Can I disable it for this lib I''m working on?
Thanks so much,
John
