// Updates the document
- (BOOL) updateWorkout:(NSDictionary *) workout {
NSError *error;
// retrieve the document from the database
CBLDocument *getDocument = [database documentWithID: [[workout
objectForKey:@"workout"] objectForKey:@"workout_id"];
// make a mutable copy of the properties from the
document we just
retrieved
NSMutableDictionary *docContent = [getDocument.properties
mutableCopy];
// modify the document properties
docContent[@"exercises"] = [[workout objectForKey:@"workout"]
objectForKey:@"exercises"];
// save the Document revision to the database
CBLSavedRevision *newRev = [getDocument putProperties:docContent
error:&error];
if (!newRev) {
NSLog(@"Cannot update document. Error message: %@",
error.localizedDescription);
}
// display the new revision of the document
NSLog(@"The new revision of the document contains: %@",
newRev.properties);
return YES;
}
The given workout is a wrapper dictionary with a key @"workout" and the value
is a dictionary that contains some keys-values.
This method is pretty the same as the tutorial's one.
Have I to put manually a _rev property in document at the moment of insertion?
