Best way to map subrequest without manual add/remove about fasteasymapping HOT 7 CLOSED

@k06a basically all you need is to "replace" old menus by new one with reuse of existing? Am i right?

In this case this code should help you:

FEMManagedObjectMapping *placeMapping = ...;
FEMManagedObjectMapping *menuMapping = ...;

FEMRelationship *menuRelationship = [[FEMRelationship alloc] initWithProperty:@"menuRelationshipPropertyNameForPlace" keyPath:@"keyPathForMenusInJSON" assignmentPolicy:FEMAssignmentPolicyCollectionReplace objectMapping:menuMapping];

[placeMapping addRelationship:menuRelationship];

from fasteasymapping.

@k06a
Also does http://.../api/json/GetPlaceMenu?place_id=%@ contain identifier of place or just nested menus?

from fasteasymapping.

@dimazen, Menu json does not contains parent place_id.

from fasteasymapping.

@k06a ok, in this way you probably need something like that:

EMManagedObjectMapping *placeMapping = empty mapping with entity name. ;
FEMManagedObjectMapping *menuMapping = real mapping of menu;

FEMRelationship *menuRelationship = [[FEMRelationship alloc] initWithProperty:@"menuRelationshipPropertyNameForPlace" keyPath:nil assignmentPolicy:FEMAssignmentPolicyCollectionReplace objectMapping:menuMapping];

[placeMapping addRelationship:menuRelationship];

After you're done with mapping execute this code

[FEMManagedObjectDeserializer fillObject:userPlace fromExternalRepresentation:dictionaryFromNetwork usingMapping:placeMapping];

@dimazen thanks!

@dimazen I am using deserializeCollectionExternalRepresentation and I am falling on NSAssert on FEMCache.m:94:

NSAssert(
    NO,
    @"Expected container classes: NSArray, NSDictionary. Got:%@",
    NSStringFromClass([representation class])
);

I found similar problem and similar solution here: #26 But it is not working for me.

@k06a hm, can you share the JSON & mapping?
