I’m using to_xml to provide XML export model objects. I’m looking for
a simple solution to implement the reverse, so that I can reconstruct
the model objects from the XML.
Using Hash.from_xml I can parse the XML into a Hash and pass this into
m = Model.new(hash)
Whilst this works fine for simple models it doesn’t (seemingly) work
with relationships. Take the following example:
class Account has_many :users end
The XML produced by to_xml is:
<account> <id>1</id> <users> <user> <id>1</1> </user> </users> </account>
Calling Account.new(hash) results in
“ActiveRecord::AssociationTypeMismatch: User expected, got Array”,
which is to be expected because the initialize method doesn’t
configure relationships in this way (I don’t think).
Does anyone have a proper solution for this problem, perhaps by
extending ActiveRecord, or is it just a matter of manually
reconstructing each of the relationships?
Thanks in advance.
