A few months ago, after I saw that how the new EOModeler saves
EOFetchSpecifications in property list files I posted a message to the list
asking about converting EOFetchSpecifications and other objects to and from
property list files. This would be generally useful for, among other
things, saving objects to the database.
Someone sent me some methods for EOFetchSpecification to do this, but I've
only just gotten around to trying out they sent me and I'm having problems.
Specifically, this code snippet:
EOFetchSpecification *fetchSpecification =
[EOFetchSpecification fetchSpecificationWithEntityName:@"IDUser"
qualifier:qualifier
sortOrderings:nil];
NSLog (@"fetchSpecification: %@", fetchSpecification);
[[fetchSpecification description] propertyList]
Generates this output:
Mar 20 22:34:50 TestFoo[403] fetchSpecification: {
entityName = IDUser;
fetchLimit = 0;
hints = {};
isDeep = YES;
prefetchingRelationshipKeyPaths = nil;
promptsAfterFetchLimit = NO;
qualifier = (username = 'digital');
rawRowKeyPaths = nil;
requiresAllQualifierBindingVariables = NO;
sortOrdering = nil;
usesDistinct = NO;
}
Mar 20 22:34:50 TestFoo[403] *** Uncaught exception: <NSParseErrorException>
*** Separator ')' expected;
Parse error line 8 (position 190) for units: (xObject, Dictionary,
parseDictionary, xObject, Array, parseArray);
Next token is '='
stack: 0x32040b0e 0x320411eb 0x3203b17f 0x4010c8 0x40129c 0x77f1b304
If I grab that string and call propertyList on it, it does the same thing.
However, if I remove the "qualifier = . . . " line from it, it works.
Anyway, what's the right way to do this?
Is there some private API EOF is using to encode and decode the FetchSpecs?
Thanks.
