is RestKit has default mapping if omit some field

Question

my json and object both contain some fields with same name, and my mapping like this:

[mapping addAttributeMappingsFromArray :@[ @"postId", @"fieldname1", @"fieldname2", @"fieldname3", @"fieldname4", @"fieldname5"]];

if json was returned without fieldname4, it is fine, the mapping just ignore it.

but on the contrary, if I forget some field in mapping, for example.

[mapping addAttributeMappingsFromArray :@[ @"postId"]];

then the object will got nothing except postId even if json contains every field.

is there someway I can tell the mapping to do some "default mapping" if json and object contained same field name. So I need not list all the field names to the mapping even if their field names are all same.

No. You explicitly list the keys which should be processed.

You could create a dynamic mapping which introspects on the response and the destination object and creates a mapping including all keys. RestKit doesn't do that because it's slow...
