Object Nesting in LRestClient

 Published On June 18, 2015

Recently the backend guys I work with in a project decided to change the response format from:

[obj1, obj2... ]


{success=1, result=obj}
{success=1, results=[obj1, obj2... ]}

Which made me realized that althought I’ve added path support for the object based scenario, format like {success=1, results=[obj1, obj2... ]} hadn’t been supported yet. So I added the missing code and both the scenarios are covered now. You can simply add:

client.path = "result"
client.path = "results"

So that LRestClient looks for the path key in the response data, and tries to parse from there instead of the root level. Of course, this is not the ideal solution since information of success will be discarded, and if you’re starting from scratch or you have time to refactor the whole project, what you should start with is something like:

class MyAnotherModel: LFModel {
	var success: Int = 0
	var error: String?
	var object: MyObjectModel?
	var objects: [MyObjectModel] = []
    required init(dict: LTDictStrObj?) {
        super.init(dict: dict)
		reload("object", type: NSStringFromClass(MyObjectModel))	//	reload as object
		reload("objects", type: NSStringFromClass(MyObjectModel))	//	reload as array

However, if you’re already in the middle of something and just want everything to work again, or you don’t care about other parameters anyway, then the path key can be really useful.

PS: as I commented inside LClient.swift, I should add nesting support for path later, which means you can find a nested object inside the response data. I’m not really having a real life case that this feature is actually needed so I’m leaving it there, and it’s not hard to implement anyway.
