Common Save Patterns

Standard background save

Assuming that you don't care which NSManagedObjectContext is used, and you just want to make some changes and save them in the background, use the following method. 90% of the time, this is what you'll want.

NSManagedObjectSubclass *myObject = [NSManagedObjectSubclass MR_findFirst];

[MagicalRecord saveWithBlock:^(NSManagedObjectContext *localContext) {

It appears that Safari does not enforce any kind of access
restrictions for XMLHTTPRequests on FILE: scheme URLs.  As a
result, any HTML file on the local file system that is opened in
Safari can read any file that the user has access to (and, of
course, it can upload those files too).  Here's a little
proof-of-concept.  Copy and paste this into a local HTML file and
open it in Safari.  It will display the contents of /etc/passwd.
