iphone and gis development notes

1. I was trying to get the http headers dump from a mobile phone. So I quickly dump it in a log file to see its contents..

    headers['Content-Type'] = 'text/xml; charset=utf-8'
    for header in request.env.select {|k,v| k.match("^HTTP.*")}
        logger.info(header[0].split('_',2)[1] + ":" + header[1])
    end

2. However, please note that you can actually see everything from the request as parameters.

Parameters: {“MSAG-ADDRESS-PREFIX”=>”aSTARTa”, “format”=>”xml”, “protocol”=>”ussd”, “user-agent”=>”Jakarta Commons-HttpClient/3.0.1″, “WHOISD-ABONENT”=>”8613520747210″, “action”=>”menu”, “controller”=>”ussd”, “subscriberID”=>”8613520747210″, “WHOISD-USR”=>”-1″, “host”=>”wap.watago.mobi”, “WHOISD-USSD-MESSAGE”=>”", “content-length”=>”0″}

This means we can easily do..

@whoisd_abonent = params['WHOISD-ABONENT'] || nil

If you want user_id to be ‘nil’, then omit it from your fixtures. I tried setting user_id: nil before, and it turned out to be ’0′ in the database.

# Read about fixtures at http://ar.rubyonrails.org/classes/Fixtures.html
<% u = UserLogin.create( :password => 'foo') %>
<% u.password=('password') %>
 
user_no_profile:
 email: noprofile@yahoo.com
 admin: false
 user_id: nil
 salt: <%= u.salt %>
 salted_password: <%= u.salted_password %>

# Read about fixtures at http://ar.rubyonrails.org/classes/Fixtures.html
<% u = UserLogin.create( :password => 'foo') %>
<% u.password=('password') %>
 
user_no_profile:
 email: noprofile@yahoo.com
 admin: false
 salt: <%= u.salt %>
 salted_password: <%= u.salted_password %>

Before pulling your hair out on what went wrong with your functional tests, check the test database if you have the correct values in your records. Remember ’0′ is different from ‘nil’.
