Hi guys
I would like to show in the magritte chapter I'm revisiting a bit more meat. I'm playing with magritte 30 and I would like to know if there is a way to save objects based on their magritte description.
Yes, there is. There is a description in an old blog post of mine [1]. Don't be misled that magritte2 is mentioned there. It works as well with magritte3 (thanks to Nick Ager). You can get it
Gofer new renggli: 'magritte3addons'; package: 'ConfigurationOfMagritte3AddOns'; load
and load the default.
Excellent I will read it. I'm reading magicMagritte right now. BTW the Twitters stuff of nick is gorgeous :)
In a nutshell:
You add to your descriptions "beXmlAttribute" or "beXmlElement". Then you can store an object with
myObject magritteDescription toXml: myObject
Ok cool. I did that by hand in the past importElement: aXMLItem | anElement | anElement := (self class mappingTable at: aXMLItem name) new. self updateBackLinkOf: anElement. anElement magritteDescription do: [ :each | | auth | auth := aXMLItem attributeAt: each accessor readSelector asString. (#(nil 'nil' ) includes: auth) ifFalse: [ auth := each fromString: auth. each accessor write: auth to: anElement ]]. self base add: anElement. ^ anElement
hope that helps,
Do you know how relationships are handled :)
