Question

I’m parsing some JSON which comes to me in this format:

{
dataId = "823o7tr23d387g";
category = "link";
details = {
    text = "Some text associated with the link";
    url = "http://www.url.com";
    thumbnail_url = "http://www.url.com/picture.jpeg";
};
source = "CNN";
},
{
...
},

MagicalRecord has a great importing method: + (id) importFromObject:(id)data; but does it support dictionaries inside the JSON dictionary so that it can automatically map the details {} to the appropriate properties?

Is there a naming convention or something I will need to use?

Check out this article about using MagicalRecord to automatically import JSON, specifically the data keypath support section

Data Keypath Support

Key Value Coding is a common and effective tool in Objective C.
MagicalImport gives you access to some of this power by allowing you
to specify keyPaths as part of a mappedKeyName. If you’re familiar
with KVC, this should be a fairly straightforward feature as
Magicalmport passed these specified keys to the KVC methods under the
covers. Keypath support allows you to map data to an entity that may
not have exactly the same hierarchy as the data model. For example, a
data entity may store latitude and longitude, but the source data
looks more like this:

{
  "name": "Point Of Origin",
  "location":
  {
    "latitude": 0.00,
    "longitude": 0.00
  }
}

In this case, we can specify as our data import key paths,
location.latitude and location.longitude in our mappedKeyName
configuration to dig into the nested data structure and import those
values specifically into our core data entity.
