I'm having a heck of a time accessing an sqlite3 database file that's in the resource file.
This doesn't throw an error: dbFileName=':/pyqtdeploy_ptest1/testSqlite3.db' qtDbFile=QtCore.QFile(dbFileName)So I know that the file exists and can be sen by the pyqt APIs
But according to the tutorial we can't use the "standard Python file access functions" http://pyqt.sourceforge.net/Docs/pyqtdeploy/tutorial.htmlSo something like this is a no-no: dbFileName=':/pyqtdeploy_ptest1/testSqlite3.db'
Unfortunately the sqlite3.connect() call takes a file name.
I've tried with and without the ':' character. conn = sqlite3.connect(":/pyqtdeploy_ptest1/testSqlite3.db?mode=ro") conn = sqlite3.connect("/pyqtdeploy_ptest1/testSqlite3.db?mode=ro")I've even tried the uri argument approach:
conn = sqlite3.connect("file:/pyqtdeploy_ptest1/testSqlite3.db?mode=ro", uri=True)and with an extra ':' character: conn = sqlite3.connect("file::/pyqtdeploy_ptest1/testSqlite3.db?mode=ro", uri=True)
The error I keep getting is: sqlite3.OperationalError: unable to open database file
I've thought about using QFile, getting the file descriptor and then copying the file to the IPad's /tmp directory but that's my last resort.
What would be the proper way to open the sqlite3 database?
