keypath: to allow array index targeting "AnArray.0.ObjectOfArrayItem"
Closed this issue · 3 comments
Greets,
Can we make keypath respect array indexes to target a specific array before parsing. I'm trying to access "AnArray.0.ObjectOfArrayItem", i.e.
.responseArray(queue: nil, keyPath:"Galleries.0.Images") {
To parse the first Gallery from an array's Images tag as the starting point
{
"Galleries":[
{
"GalleryField":"First gallery has Images of interest",
"Images":[
{
"URL":"http://example.com",
"Caption":"First Image"
},
{
"URL":"http://example.com",
"Caption":"Second Image"
}
]
},
{
"GalleryField":"Subsequent galleries are not of interest",
"Images":[
{
"URL":"http://example.com",
"Caption":"inb4404"
},
{
"URL":"http://example.com",
"Caption":"MOAR IMG!!!"
}
]
}
]
}
This prevents having to create redundant classes for top-level items
I have been considering adding this as well. I've marked this as an enhancement to keep track of it until I have time to work on it.
Feel free to make a Pull request if you would like to add the functionality
Bump, I think this is pretty useful as well... I am using ObjectMapper
with AlamoFire
through AlamofireObjectMapper
and some of the API results include an array containing a single object (which is not that great API design, but that's what I need to work with.)
Example:
// get the first element in the array
let keyPath = "result.0"
Alamofire.request(...).responseObject(queue: dispatchQueue, keyPath: keyPath) { ... }
Example JSON response:
{
"result":[
{
"someObject": { ... }
}
]
}
As a workaround I am now using responseArray
and getting the first object which works but responseObject
would be more appropriate in this case...
+1, this would be useful.
