Hello, I am using ActiveResource to integrate with a 3rd party service. when calling MyModel.save a POST with xml is sent. I need to make sure that xml is created with defined order of elements. How can I do that? Some have suggested using rxml or builder, but I am not sure how. Has anyone done this before? thank you
I''m not sure what you mean by order, but if you are working with a
list of items you can order the array and the to_xml will reflect
that. Otherwise if by order you mean having different xml blocks in a
post request then use a hash. The order in which the items are
contained within the xml won''t matter as long as they are all there
and in the proper structure. For example, say we are using a person a
payment and a product, and the payment is in the person block.
h = Hash.new
h[''person''] = Person.first.attributes
h[''person''][''payment''] = "$100.00"
h[''product''] = Product.first
h.to_xml(:root => ''notification'')
would result
<notification>
<person>
<attr></attr>
<payment>$100</payment>
<maybe_another_attr></maybe_another_attr>
</person>
<product>
<attr></attr>
<attr2></attr2>
</product>
</notification>

I need to make sure that when I call
SalesDocument.save
the order of elements in the xml is predetermined and consistent,
which currently not the case.
POST http://<myurl>/sales_documents.xml
body: <?xml version="1.0" encoding="UTF-8"?>
<sales-document>
<items type="array">
<item>
<quantity type="float">3.0</quantity>
<product>AD_DASHERBOARD-200</product>
</item>
</items>
<sales-group>110</sales-group>
<division>10</division>
<sales-office>110</sales-office>
<ref-inquiry>Sales Lett</ref-inquiry>
<distr-channel>10</distr-channel>
<document-type>AG</document-type>
<customer>0000100007</customer>
<sales-org>1100</sales-org>

Hello,
I am using ActiveResource to integrate with a 3rd party service.
when calling MyModel.save a POST with xml is sent.
I need to make sure that xml is created with defined order of
elements (the service requires it) How can I do that?
Some have suggested using rxml or builder, but I am not sure how. Has
anyone done this before?

thanks, I am not sure how to make my model convert to xml for POST according to builder rules... currently it uses a hash to represent all fields and calls hash.to_xml but hash is unordered so no predictability. this is my specific problem :) Hassan Schroeder wrote:> On Mon, Aug 3, 2009 at 10:56 PM, Slava > Mikerin<rails-mailing-list-ARtvInVfO7ksV2N9l4h3zg@public.gmane.org> wrote: > >> I am using ActiveResource to integrate with a 3rd party service. >> when calling MyModel.save a POST with xml is sent. >> I need to make sure that xml is created with defined order of >> elements (the service requires it) �How can I do that? >> Some have suggested using rxml or builder, but I am not sure how.

I am stuck.. here is what i tried
class SalesDocument < ActiveResource::Base
def encode
SalesDocumentsController.new.render_to_string :template,
''rxml-file''
end
end
But that does not work. I get:
NoMethodError: protected method `render_to_string'' called for
#<SalesDocumentsController:0xb6fd111c>

I don''t think that''s what you want. -- Posted via http://www.ruby-forum.com/.
ok. I found solution :)
Here is what I did
class SalesDocument < ActiveResource::Base
def encode
builder = Builder::XmlMarkup.new(:indent=>2)
builder.instruct!
builder.tag!(''sales-document''){
builder.items(''type'' => ''array''){
self.items.each do |item|
builder.item{
builder.quantity(item.quantity, "type" =>
"float")
builder.product(item.product)
builder.id(item.id) if item.id
}
end
}
builder.tag!(''sales-group'', self.sales_group)
builder.tag!(''sales-office'', self.sales_office)
builder.tag!(''ref-inquiry'', self.ref_inquiry)
builder.tag!(''distr-channel'', self.distr_channel)
builder.division(self.division)
builder.tag!(''document-type'', self.document_type)
builder.customer(self.customer)
builder.tag!(''sales-org'', self.sales_org)
builder.id(self.id) if self.id
}
builder.target!
end
end

BTW, it''s more idiomatic Ruby to use do/end for multiline blocks and save { } for one-liners.
