Hi all
Is it possible to steer where a QML application stores its
OfflineStorage Database?
I have a family of applications that share a common OfflineStorage
Database. This works well on Harmattan, and on the early Sailfish
Alphas without me having had to do anything special at all.
In the early Sailfish Alphas OfflineStorage DBs were stored in a
common location, and thus could be easily shared.
/home/nemo/.local/share/data/QML/OfflineStorage/Databases
Now on the real Jolla, I find that the standard DB storage location
has changed, and DBs are now put in a subdirectory of the
application's installation folder. e.g.
/home/nemo/.local/share/landed25_QT5/QML/OfflineStorage
/home/nemo/.local/share/CreateDBQt5/QML/OfflineStorage
This means without some magic, Sailfish apps can no longer share DBs.
In C++ there is a property offlineStoragePath, and a setter method
setOfflineStoragePath().
http://qt-project.org/doc/qt-5/qqmlengine.html#offlineStoragePath-prop
I might be able to use this to change the location of the DB, e.g to
one of the Qt StandardLocations:
http://qt-project.org/doc/qt-5.0/qtcore/qstandardpaths.html#StandardLocation-enum
But setOfflineStoragePath() appears not to be directly available to QML.
http://stackoverflow.com/questions/14209585/how-to-set-custom-offline-storage-path-from-javascript-in-qtquick
So I guess I could call setOfflineStoragePath in each apps' main cpp file.
Or maybe I could even write a declarative plugin to expose
setOfflineStoragepath to QML, but that is probably overkill as it
would instantiate QQmlEngine - just t o set a path.
Or is there a better way? Are there any Harbour entry considerations
to an app creating / accessing a DB somewhere other than in its own
folder?
Thanks
Chris
