[web2py] How can I check if an application is installed from within routes.py?
In my production environment, new web2py apps are installed every day.
In fact, it is the same app that it is installed several times with a
different name.
Each installed application corresponds to a website that has its own domain.
In the root folder of web2py, I have a file called "domains_apps" where I
store which domain corresponds to which application.
The file looks like this:
domain1.com!app1
domain2.com!app2
domain3.com!app3
Then, in my routes.py file I read the domains_apps file to construct the
"domains" dictionary that is provided for the routers.
My routes.py file looks like this:
# -*- coding: utf-8 -*-
domains = {}
archivo = open('domains_apps', 'r')
lines = archivo.readlines()
archivo.close()
for line in lines:
if line:
domain, app = line.split('!')
if domain and app:
domains[domain] = app
routers = dict(
BASE=dict(
default_controller='default',
default_function='index',
domains=domains,
root_static=['robots.txt', 'ads.txt'],
map_static=True,
exclusive_domain=True,
)
)
This works smoothly.
Now I'm trying to add a checkpoint: before adding an domain/app, I would
like to check that the application is indeed installed in web2py. *How do I
do that?*
I've tried checking if the folder exists inside applications folder, but it
doesn't work (I created an empty dir and it does pass the validation, but
then web2py throws an error saying application doesn't exist).
I've also tried checking if the folder exists and it has an __init__.py
file inside it, but it doesn't work (again, I tried creating a folder with
an __init__.py file inside, it passes validation but web2py throws error
saying application doesn't exist).
You may wonder why do I need to check that in routes.py?
Well, as applications are installed/removed by an external process,
something could break during this process. And if for some reason my
domains_apps file ends up including an application that was removed, my
uWSGI instance will fail loading the application, and all my requests will
fail.
So, considering the routes.py I previously showed, how can I check if an
application exists?
Does this approach make any sense?

[web2py] Re: pyDAL "adapter" for Pandas syntax (phylosophical)
Sorry to dig this thread up, but I had to take a look at this recently. I think the most efficient way is to use pydal to make the sql query and then have pandas do it. As an example say you want a dataframe which has the user's id and their first_name import pandas as pd conn = db._adapter.connection sqlquery = pd.read_sql_query(db(db.auth_user.id > 0)._select(db.auth_user.id , db.auth_user.first_name), conn) df = pd.DataFrame(sqlquery, columns=["id", "first_name"]) This uses the connection to the database already done by pydal, it uses sql produced by pydal, however pydal does not process the result as it goes directly to pandas. -- Resources: - http://web2py.com - http://web2py.com/book (Documentation) - http://github.com/web2py/web2py (Source code) - https://code.google.com/p/web2py/issues/list (Report Issues) --- You received this message because you are subscribed to the Google Groups "web2py-users" group.

[web2py] Re: Web3py
Hi All,
Finally gotten round to playing again on the latest Web3py.
On _scaffold app .. if I add new tables to model file and then reload from
the dashboard .. I get errors as follows:-
File "C:\Users\johhb\py3\lib\site-packages\pydal\base.py", line 581, in
define_table
raise SyntaxError('table already defined: %s' % tablename)
File "", line None
SyntaxError: table already defined: auth_user_tag_groups
Only way around it seems to be to delete contents of database folder and
restart.
Dashboard app hangs on reload sometimes (I think it has to do the with same
issue above) and only way to get round it is to restart the server and
refresh the _dashboard app.
I really want to start using it to create a few new apps I am due to start
working on shortly even though I am well aware that it is not yet
production ready so will keep testing and assist wherever I can. Thanks
again for all the hard work put in so far I am sure its gonna be a really
cool solution.
Best Regards
John

[web2py] ignore_common filters not applied to left join table
Not sure if it is a bug, feature or inconsistancy but ignore_common filters not applied to left join table in query with left join. I would expect that ignore is for all. Not a big issue because you can set the commonfilter on the respected tables to None just before query execution. -- Resources: - http://web2py.com - http://web2py.com/book (Documentation) - http://github.com/web2py/web2py (Source code) - https://code.google.com/p/web2py/issues/list (Report Issues) --- You received this message because you are subscribed to the Google Groups "web2py-users" group.

[web2py] nssm does not work
I am using the latest version of NSSM - the Non-Sucking Service Manager; both 2.24 and the prelease build 2.2.4-101 . Unfortunately for me, NSSM sucked big time and trying to get it working with web2py was an utter waste of time. Tried -K; nothing and tried -X; nothing anyways Env: Python3.7 Windows 10 Can anyone advise what is supposed to happen after issuing -K app1 ? A windows pop-up or the local webserver starts ?
