Asp Forum - Simple problem w/ WWW::Mechanize

Hi all, I'm fairly new to Ruby, and, as an exercise, I'm writing some
code for webforms. However, I can't seem to get the following code to
work - instead, I get the following error:
wikitesting.rb:8:in `get': undefined method `myform' for
#<WWW::Mechanize::Page:0xb7996738> (NoMethodError)
from wikitesting.rb:10

Probably pretty simple, and I can see it's something wrong with the
way I called the function, however, I've spent some time on it and
can't figure it out. Here's the code:
require 'rubygems'
require 'mechanize'
def get(pagename)
agent = WWW::Mechanize.new
agent.user_agent = 'Mozilla/4.0 (compatible; MSIE 6.0; Windows NT
5.1)'
page = agent.get('http://en.wikipedia.org/w/index.php?t... +
pagename + '&action=edit')
myform = page.form('editform')
return page.myform.fields.form('wpTextbox1')
end
text = get('Computer')
pp text

Thanks,

Tim

Try replacing this line:

> return page.myform.fields.form('wpTextbox1')

With this:

return myform.wpTextbox1

You've already found the form and stored it in the 'myform' variable.

Thanks for replying. I still get a similar error, though:
wikitesting.rb:8:in `get': undefined method `wpTextbox1' for
nil:NilClass (NoMethodError)
from wikitesting.rb:10

Any ideas? By the way, I've joined the mailing list, and any future
questions I might have will probably be directed there.

Thanks,

Tim

It looks like Wikipidia may not like that parameter in the URL. When I
change 'Computer' to 'Main', it seems to work:

require 'rubygems'
require 'mechanize'

def get(pagename)
agent = WWW::Mechanize.new
agent.user_agent = 'Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1)'
page = agent.get('http://en.wikipedia.org/w/index.php?t... +
pagename + '&action=edit')

myform = page.form('editform')
return myform.wpTextbox1
end
text = get('Main')
pp text

Actually this is about bad loans to liars. People lying, saying they
earn more than they do, mortgage loan companies not caring whether
they told the truth or not because they're going to flip that mortgage
to some other firm that will turn it into an investment fund.

I've also heard a lot of these people with bad loans are the imbeciles
who watched a show on Discovery channel about flipping properties so
they figured they'd lie about their income to get the loan, then they
got in over their head and couldn't sell the property at the price
needed and couldn't keep up the payments.

I say let 'em go south, those that are going and let the dust settle.
This isn't spreading to other industries and not all those that
they're talking about being at risk will turn out to be dead beats.
Not all 7 million.
