There are whole sections based on assumption that sqlite has no built-in DictCursor behavior

Besides verbosity, by wrapping result in dict() we block transparent data passing to INSERT which waits for "tupled" format

Here is solution:
db = sqlite3.connect(app.config['DATABASE_NAME'])
db.row_factory = sqlite3.Row # trick!

While "print cur.fetchall()" still looks like tuples are here... don't worry, it supports key access:

for item in cur.fetchall():
print item['title'] # works!

So you can easily remove those custom wrappers which i saw copied here and there...


Sounds like a good idea. Do you want to update the docs and send me a pull request?

points out the "Easy Querying" section on how to convert to a
