newbie question - writing derived view back to db

Hello everyone,

I'm new to Metakit and I use it via the Python interface. What I have
trouble figuring out is how to write the derived view back to the db.

I wrote this script that stores the word with its integer index in the
db (code below). Now supposed I get the view with:

import metakit
db=metakit.storage('small.mk',1)
vw=db.view('words')

..then sort it:

vw2=vw.sort('word')

I checked that it gives me derived view sorted as I expected.


However, then I stumbled on seemingly silly problem: how do I write
the damn thing back to the db? db.commit() doesn't seem to write the
changes back to db.

I can always use storage.save(new_fileobj) and then delete the old db.
However, that's a lot of rigmarole just to write the changed view
back.






# begin of code

import metakit

bwl = list(open('smallist.txt').readlines())

db = metakit.storage('small.mk',1)
vw = db.getas('words[word:S,idx:L]')

for word, idx in zip(bwl, range(0,len(bwl))):
    vw.append(word=word.strip('\n'),idx=idx)

db.commit()

# end of code





  
Regards,
Marcin
