I''m having trouble using Hash.from_xml, so I dropped into script/
console to see what was happening.>> t = Trackable.find(1)
=> #<Activity:0xb707e5b0
@attributes={"visibility"=>"0",
"code"=>"K",
"type"=>"Activity",
"disposition"=>"2", "id"=>"1",
"description"=>"Kahu",
"owner_id"=>"3",
"projected_completed_at"=>nil,
"parent_id"=>nil, "created_at"=>"2007-08-17
19:19:27"}>>> a = t.attributes
=> {"visibility"=>0, "code"=>"K",
"type"=>"Activity", "id"=>1,
"disposition"=>2, "description"=>"Kahu",
"projected_completed_at"=>nil, "owner_id"=>3,
"parent_id"=>nil,
"created_at"=>Fri Aug 17 19:19:27 UTC 2007}>> a.to_xml
=> "<?xml version=\"1.0\"
encoding=\"UTF-8\"?>\n<hash>\n <visibility
type=\"integer\">0</visibility>\n
<code>K</code>\n <type>Activity</
type>\n <id type=\"integer\">1</id>\n <disposition
type=\"integer
\">2</disposition>\n
<description>Kahu</description>\n <projected-
completed-at nil=\"true\"></projected-completed-at>\n
<owner-id type\"integer\">3</owner-id>\n <parent-id
nil=\"true\"></parent-id>\n
<created-at
type=\"datetime\">2007-08-17T19:19:27Z</created-at>\n</
hash>\n">> puts a.to_xml
<?xml version="1.0" encoding="UTF-8"?>
<hash>
<visibility type="integer">0</visibility>
<code>K</code>
<type>Activity</type>
<id type="integer">1</id>
<disposition type="integer">2</disposition>
<description>Kahu</description>
<projected-completed-at
nil="true"></projected-completed-at>
<owner-id type="integer">3</owner-id>
<parent-id nil="true"></parent-id>
<created-at
type="datetime">2007-08-17T19:19:27Z</created-at>
</hash>
=> nil>> Hash.from_xml(a.to_xml)
=> {"hash"=>nil}
That doesn''t work, but this does:
>> h = {''a'' => ''1'',
''b'' => ''2''}
=> {"a"=>"1",
"b"=>"2"}>> h.to_xml
=> "<?xml version=\"1.0\"
encoding=\"UTF-8\"?>\n<hash>\n <a>1</a>\n
<b>2</b>\n</hash>\n">> puts h.to_xml
<?xml version="1.0" encoding="UTF-8"?>
<hash>
<a>1</a>
<b>2</b>
</hash>
=> nil>> Hash.from_xml(h.to_xml)
=> {"hash"=>{"a"=>"1",
"b"=>"2"}}
I''m using Rails 1.2.3.
Am I doing anything wrong, or is from_xml not working properly?
