py4web
Try me (from pip)
python3 -m pip install -U py4web --no-cache-dir --user
py4web setup apps
py4web set-password
py4web run apps
open http://localhost:8000/todo/index
(The apps folder will be created with some apps inside)
Try me (from source)
git clone https://github.com/web2py/py4web.git
cd py4web
python3 -m pip install -r requirements.txt
./py4web.py setup apps
./py4web.py set-password
./py4web.py run apps
open http://localhost:8000/todo/index
Try me (install from source)
git clone https://github.com/web2py/py4web.git
cd py4web
make assets
make test
make install
py4web run apps
open http://localhost:8000/todo/index
Notice "py4web" uses the pip installed py4web, "./py4web.py" uses the local one. Do not get confused. Also notice when installing from source the content of py4web/assets is missing and it is created by make assets.
Tell me more
- this is a work in progress and not stable yet but close to being stable
- python3 only
- uses https://github.com/web2py/pydal (same DAL as web2py)
- uses https://github.com/web2py/yatl (same as web2py but defaults to [[...]] instead of {{...}} delimiters)
- uses the same validators as web2py (they are in pyDAL)
- uses the very similar helpers to web2py (A, DIV, SPAN, etc.)
- uses https://github.com/web2py/pluralize for i18n and pluralization
- request, response, abort are from https://bottlepy.org
- HTTP and redirect are our own objects
- like web2py, it supports static asset management /{appname}/static/_0.0.0/{path}
- implements sessions in cookies (jwt encrypted), db, memcache, redis and custom
- implements a cache.memoize (Ram cache with O(1) access) Memoize
- supports multiple apps under apps folder (same as web2py)
- unlike web2py does not use a custom importer or eval
- admin has been replaced by a _dashboard (90% done)
- appadmin has been replaced by dbadmin (within dashboard) (90% done)
- auth logic is implemented via a "auth" vue.js custom component (90% done)
- SQLFORM has been replaced by py4web/utils/form.py
- SQLFORM.grid was been replaced by a "mtable" vue.js custom component (90% done)
- there are not enough tests
- it is not as stable as web2py yet
- it is 10-20x faster than web2py

Storing _dashboard password
When py4web starts it asks for a _dashboard password and stores its pdkdf2 hash
in password.txt, in the working folder. It will not ask again unless the file is deleted.
If the --dashboard_mode
is demo
or none
it will not ask.
If you want to store it somewhere else, you can specify a name with --password_file
.
You can create the file yourself with:
$ python3 -c "from pydal.validators import CRYPT; open('password.txt','w').write(str(CRYPT()(input('password:'))[0]))"
password: *****
Launch Arguments
Usage: py4web.py run [OPTIONS] [APPS_FOLDER]
Options:
-Y, --yes No prompt, assume yes to questions
-H, --host TEXT Host name (default 127.0.0.1)
-P, --port INTEGER Port number (default 8000)
-p, --password_file TEXT File for the encrypted password
-w, --number_workers INTEGER Number of workers
-d, --dashboard_mode TEXT Dashboard mode: demo, readonly, full
(default), none
--watch [off|sync|lazy] Watch python changes and reload apps
automatically, modes: off (default), sync,
lazy
--ssl_cert TEXT SSL certificate file for HTTPS
--ssl_key TEXT SSL key file for HTTPS
--help Show this message and exit.
Example:
py4web run -H 127.0.0.1 -P 8000 -d demo apps
Note that since the default (as specified above) for the host and port are 127.0.0.1 and 8000 respectively, the above command can be shortened to:
py4web run -d demo apps
WSGI
py4web is a WSGI application. To obtain the WSGI app simply do:
from py4web.core import wsgi
application = wsgi()
The wsgi function takes arguments with the same name as the command line arguments.
