python - Separate SQLAlchemy models by file in Flask -

this question has reply here:

flask-sqlalchemy import/context issue 2 answers

many examples flask apps have seen have models stored straight in main app file (http://pythonhosted.org/flask-sqlalchemy/quickstart.html, http://maximebf.com/blog/2012/10/building-websites-in-python-with-flask/). other ones (http://flask.pocoo.org/docs/patterns/sqlalchemy/) have "models.py" file in models placed.

how can have flask app import models separate files, e.x. "user.py"? when seek creating user.py file these contents:

from app import db class user(db.model): [...]

i next error:

file "/users/stackoverflow/myapp/models/user.py", line 1, in <module> app import db importerror: no module named app

when insert from models import user in module file.

this reply extremely helpful: http://stackoverflow.com/a/9695045/353878.

i needed not initialize db right away.

Accessing MATLAB's unicode strings from C -

Accessing MATLAB's unicode strings from C - how can access underlying unicode info of matlab strings through matlab engine or mex c interfaces? here's example. let's set unicode characters in utf-8 encoded file test.txt, read as fid=fopen('test.txt','r','l','utf-8'); s=fscanf(fid, '%s') in matlab. now if first feature('defaultcharacterset', 'utf-8') , c engevalstring(ep, "s") , output text file utf-8. proves matlab stores unicode internally. if mxarraytostring(enggetvariable(ep, "s")) , unicode2native(s, 'latin-1') give me in matlab: non-latin-1 characters replaced character code 26. need getting access underlying unicode info c string in unicode format (utf-8, utf-16, etc.), , preserving non-latin-1 characters. is possible? my platform os x, matlab r2012b. addendum: documentation explicitly states "[mxarraytostring()] supports multibyte encoded characters...
