Core Data Project?

[rdelmar]

I see a couple of potential problems/errors. In the set modelURL line try “momd” as the extension instead of “mom”, and see if that gives you a non-nil model in the log.

set storeURL to applicationDocumentsDirectory()'s URLByAppendingPathComponent_(“USGPortfolioMetaTaggerData.momd”)

I’m not sure what this line should be. If you’re using sqlite, then the extension should be sqlite. I don’t know what it should be if you’re using NSXMLStoreType – I doubt it should be mom though.

Hello,

From the docs:

Compiling a Data Model

A data model is a deployment resource. In addition to details of the entities and properties in the model, a model you create in Xcode contains information about the diagram”its layout, colors of elements, and so on. This latter information is not needed at runtime. The model file is compiled using the model compiler, momc, to remove the extraneous information and make runtime loading of the resource as efficient as possible. An xcdatamodeld “source” directory is compiled into a momd deployment directory, and an xcdatamodel “source” file is compiled into a mom deployment file.

momc is located in /Developer/usr/bin/. If you want to use it in your own build scripts, its usage is momc source destination, where source is the path of the Core Data model to compile and destination is the path of the output.

Regards,

set storeURL to applicationDocumentsDirectory()'s URLByAppendingPathComponent_("USGPortfolioMetaTaggerData.momd")
            log "-----storeURL-----"
            log storeURL

I got this working but noticed the only difference in mine was I didn’t add the extension to the storeUrl. So maybe try:

set storeURL to applicationDocumentsDirectory()'s URLByAppendingPathComponent_("USGPortfolioMetaTaggerData")
           

and I did use “mom” in the line:

set modelURL to current application's NSBundle's mainBundle()'s URLForResource_withExtension_("USGPortfolioMetaTaggerData", "mom")
