Re: [Pharo-users] NeoJSON Mappings

by Esteban A. Maringolo

Additionally... it is really easy to f*ck up the image if you have circular references... :) As fast as NeoJSON is, it also fills the memory really fast. From a regular 50MB to 512MB in 2 seconds :).

NeoJSON Mappings

by Esteban A. Maringolo

Hi, I'm happily mapping my objects to JSON. But in order to reduce the payload I'm looking for a way to map my objects differently depending on whether it is the root object of the mapping or not. Let's say I have two classes with the following instvars between parenthesis: * ClassA(id, name) * ClassB(id, classA) I'm using #neoJsonMapping: to define the mappings and (NeoJsonWriter toString: classB) to get the JSON string. If in the Class B mappings I reference classA (by instVar or accessor) I get the whole ClassA instance serialized as JSON. Which is not what I want. I'd like to have only the id of classA. I know I can define a custom mapping using for:customDo: , but I'd like to know if there is another way to do that. And this relates to another point, that is how to define a schema for a whole hierarchy of objects. All my objects are descendant of a common superclass. There is no way I can do the following on different levels: super neoJsonMapping: mapper. mapper for: self do: [:mapping | mapping mapInstVars: #(foo) ] Because on every call it overwrites the mapping for the schema of the current call, ending up mapping only the instVar 'foo'. I can work my way around this by writing more, refactoring and so on. But I would like to know if Sven or somebody else who uses NeoJSON have some practice patterns that would like to share with the rest of us, mere mortals. Best regards! Esteban. -- View this message in context: http://forum.world.st/NeoJSON-Mappings-tp4677077.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Glorp + Postgres array type

by Chris

Hi, does anyone know if Glorp supports the array type in Postgres? I did a basicExecuteSQLString: and it came back with '{1,2,3}' so as if it might not be too complicated to make work for my scenario at least. I really want to do a toManyMapping using these integers in the array as a join to another table and have it resolve their objects, but wouldn't know where to start! Thanks Chris
