[web2py] web2py delimiters conflict with vue.jsz
I am currently running web2py Version
2.14.6-stable+timestamp.2016.05.10.00.21.47.
Even though that is old, it is meeting my needs.
I am currently learning vue.js and hoping to include it in my offerings.
The obvious problem is that both web2py and vue.js use "{{" and "}}" as
delimiters in their templates.
Is there a single place in web2py that I can change this to something else?
In web2py\gluon\globals.py there is:
class Response(Storage):
and within the __init__ there is:
self.delimiters = ('{{', '}}')
Could this be the place?

[web2py] Re: Field set the default value +1 on insert
The following is something that I have used in MySQL.
MySQL statement:
CREATE TABLE IF NOT EXISTS autonumbering
( Year char(4) not null default '',
Type varchar(10) not null default '',
IDint(11) not null auto_increment,
Notes varchar(64) not null default '',
CreatedOn timestamp not null default current_timestamp,
PRIMARY KEY (Year, Type, ID)
) ENGINE=MyISAM AUTO_INCREMENT=1;
Code in a model:
autoNumbering.define_table('autonumbering',
Field('Year', 'string', length=4, notnull=True,
default='', required=True, label='Year',
readable=True, writable=True),
Field('Type', 'string', length=10, notnull=True,
default='', required=True, label='Type',
readable=True, writable=True),
Field('id','id'),
Field('Notes', 'string', length=64, notnull=True,
default='', required=False,label='Notes',
readable=True, writable=True),
Field('CreatedOn', 'datetime',notnull=True,
default=datetime.datetime.now(), required=False,label='Created On',
readable=True, writable=True),
migrate=False
)
Code in a module:
def getWorkOrderNumber(Year): # Year is 4-digits, as in 2015
r = autoNumbering.autonumbering.insert(Year=Year, Type='WorkOrder')
autoNumbering((autoNumbering.autonumbering.Year == Year) &
(autoNumbering.autonumbering.Type == 'WorkOrder') &
(autoNumbering.autonumbering.id == str(r - 1))).delete()
return Year[2:] + session.CurrentYearPOLetter + str(r).rjust(5, '0')
This returns a unique, sequential 5-digit number prefixed by the last two
digits of the provided year.

[web2py] ajax issue/question
I am encountering what I think is a weird problem with an ajax call. My web page contains an iframe, which is loaded with a normal controller/view web2py request. When a button is clicked that should cause the javascript in the iframe to send an ajax request to web2py, I am seeing only a request header in the FireBug console but not a response header. In debug code in the web2py controller, I display when the ajax request is received, and it is never executed. This is the same procedure I use for ajax all the time, but the only difference here is that it is executing within an iframe. What mistake did I make? -- 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: ajax issue/question
I am looking to reduce the amount of data transferred by making this page of my application behave like an SPA (single-page application). I have searching built into the master page, and then individual records are loaded into the iframe, one at a time. When a user wants another record, they can recall the search results in a pop-up, and select the next record into the iframe. The ajax call is from javascript running in the iframe to get the results in the iframe. The call is acting like it can't find the controller. FireBug shows the code being executed, but the debug code in the web2py controller is not showing the request being received. The code works if not run in an iframe. -- 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: how about setting a standard fadeout to response.flash?
How about including jQuery jNotify? http://www.myjqueryplugins.com/

I prefer to keep web2py.js stock, to ease updates, so I add a similar
fadeout js to layout.html when I need it.
I'm not sure I'd alter the default though. App user can miss a message
that fades out quickly, so I prefer to leave such decisions to the UI
designer. We have apps that have flash messages with a fixed timeout (4-8
sec if I remember correctly), apps that have flash messages with no time
out at all and apps entirely without flash messages. All this is a valid
design approach and I see no benefit to changing the default, since one
solution will never fit all usage cases. Perhaps it would benefit web2py
users if fadeout was pre-set in code as a variable (ie. off or value in
seconds)? It would be easier to hack the setting. But then again, web2py is
a programming framework. web2py users are expected to know how to alter
such things or at least search trough the docs and google groups.
I like the idea of having flash messages with different categories (ie.
error, warning, info), which could be treated differently (sticky, fadeout,
different graphical design etc.). But isn't this pushing it too far..? I
mean, isn't it getting too complex? It does sound like a nice idea,
though...

Ales

Hi
Had a user pointing out how irritating it was that the response.flash
never goes away automatically. Found this fix thou in the group, how about
making a standard 4 second fadeout on it?
in web2py.js:
var flashBox = jQuery(.flash), flashTimer;
flashBox.click(function(){
if (flashTimer) clearTimeout(flashTimer);
flashBox.fadeOut(400, function(){jQuery(.flash).html('')});
});
flashTimer = setTimeout(function(){flashBox.fadeOut(400, function(){

[web2py] Re: Dynamic MySQL Database selection
When a user logs on, there is a field in the profile that contains the designation of the database for the institution associated with that user.

[web2py] Re: Dynamic MySQL Database selection
Yes, there is a master database that has the database designation for the
institutions.
I guess one of the things I am unclear on is how granular the Web2Py
framework is. Is there one db.py running for all sessions or is there a
db.py running for each user session?
If a db.py runs for for each user session independent of the other users,
then customizing the DAL setup in the db.py should work.
I wish there were more thorough documentation of the DAL.

Does that mean there's a master database that stores the user records so
you can access it to log in the user (i.e., before you know the user's
institution and therefore database)? In that case, maybe something like
this in the db.py model file:
auth_db = DAL('[auth db URI]')
from gluon.tools import Auth
auth = Auth(auth_db, hmac_key=Auth.get_or_create_key())
if not auth.user and not request.function == 'user':
redirect(URL('default', 'user'))
auth.define_tables()
db = DAL(auth.user.db_uri if auth.user else None)
If the user isn't logged in, that will redirect to the /default/user URL
for login. Note, the URI for the call to DAL() that defines the db
connection is either auth.user.db_uri (when the user is logged in) or None.
The reason for the None is so you still have a db instance when the user is
going to the /default/user URL for login (otherwise, any subsequent
db.define_table calls would generate errors). I think None will work, but
if not, you could also use a dummy 'sqlite:memory' URI, or even a regular
SQLite URI.

[web2py] Re: Dynamic MySQL Database selection
Thank you very much Anthony. That is exactly what I was looking for. When I started this project, I read the first few chapters, but then dived in. I must have missed the thread part.

I think the DAL is fairly well documented. This isn't really a question about the DAL, though, but about the workflow of requests coming into a web2py application. It might help if you review http://web2py.com/books/default/chapter/29/1#Model-View-Controller and http://web2py.com/books/default/chapter/29/4#Workflow. Note, the db.py file is freshly executed (in a separate thread) for each request that comes into the application. So, you can dynamically determine the database URI for a given request, and it will only apply to that particular request. Anthony
