[web2py] Re: how to find the Manhattan distance of the given question in python
El lunes, 5 de noviembre de 2012 03:01:00 UTC-3, Sanjeet Roy escribió: Assume a Taxicab is located at the origin (0,0) in the below Grid. The hori- zontal and vertical lines in the Grid is the road on which his taxi can move. If the cab wants to move to a place, say (3,4), the distance the cab has to travel is (3 - 0) + (4 - 0) = 7 units. The distance calculated in this way is called Man- hattan distance. In general, Manhattan distance between two points (x1 , y1 ) and (x2 , y2 ) is calculated as |x2 - x1 | + |y2 - y1 |. As you must be aware, the Eucledian distance between the same two points is calculated as (x2 - x1 )2 + (y2 - y1 )2 3 Figure 1: Manhattan distance Given n points to the taxicab driver located at a position (x,y), he/she has to arrange the points in the order of increasing manhattan distance. For example, If (3,4), (5,3) and (2,2) are the points given to the cab driver who is at the postion (1,1), then the driver will output (2,2), (3,4) and (5,3) as these points are in the order of increasing distance from the Taxicab position (1,1). You are required to write a program to help the driver. The input is of the following format: * The first line will contain the position of the Taxicab. For example, the position could be ((3,0)). * Next line will contain the number of points. For your program 2 = n = 100 * Next n lines will contain the points with each point on a new line. After reading the input, your program should calculate Manhattan distance from the Taxicab position and arrange the points in the order of increasing Manhattan distance. Each point should be printed in a new line. If Manhattan distance is equal for two points, first output the point that has the least x co- ordinate. For Example: INPUT (2,0) 4 (3,4) 4 (0,1) (6,7) (2,3) OUTPUT (0,1) (2,3) (3,4) (6,7) NetworkX [1]. Es much more than what you need. [1] http://networkx.lanl.gov/ --

[web2py] Problems with LOAD and redirect(..., type='auto')
Hello everybody, :)
In practice, I have a page (default/calculate.html) which in turn loads
another page (forms/mansioni.load) by means of LOAD.
Here the code of the page* default/calculate.html*:
!--some other HTML code here--
div
{{=LOAD('forms', 'mansioni.load', ajax=True)}}
/div
!--some other HTML code here--
The page *forms/mansioni.load* contains just a form, as the following code
shows.
{{=form}}
When I submit a form (correctly filled), I would like to redirect the
parent page *(default/calculate.html*) to another page.
According to the online book, this seems to be possible by using the
syntaxredirect(url,type='auto'). So I wrote the controller
*forms.py* in this way:
def mansioni():
form = SQLFORM.factory(
Field('something', 'string', requires=(IS_NOT_EMPTY()))
)
if form.accepts(request, session):
redirect(URL('default', 'someOtherPage', extension=False),
type='auto')
return dict(form=form)
Unfortunately, I get the following error:
TypeError: redirect() got an unexpected keyword argument 'type'
It looks like there is no such an argument for the method *redirect*.
The web2py version I am using is: 2.2.1 (2012-10-29 09:31:46) stable.
The application is running on GAE.
Some thoughts? :)
Best,
David

Unless I misunderstand your intention, I don't think that is possible. Pygame is made for desktop applications.

[web2py] How many error tickets does a typical newbie handle?
The other day I read on web2py developers a discussion detailing Massimo's
vision of web3py. Perhaps us newbies can start collecting our tickets to
aide Massimo and the developers in understanding what is particularly
difficult or perhaps could use better documentation. Currently I have *480
tickets since 10/8* on my application before I decide to re-do it from
scratch for the 4th (hopefully last) time. Tickets would provide a wealth
of statistics about what us newbies are going through.
This time I decided to break my app up into 4 smaller applications. Start
over and my 2nd try this morning (after deleting and starting over) I
currently have 19 tickets in 45 minutes. When developing using SQLite I am
now getting the same errors that I had early on in my development
Adding columns is not trivial especial with all the combinations of:
migrate_enabled={True|False}, fake_migrate={True|False},
migrate='web2py_session_APPNAME', migrate.settings={True|False},
migrate={'table_name'|True|False|migrate.settings}. My approach was to use
the wizard to quickly whip out the app then add extra fields later so that
i can develop in small iterations. If just the tickets for what I am going
through this morning could be eliminated that would be huge!
FWIW,
Bill

[web2py] How to add a column?
Can't beleive this question does not come up in the search box. How do i add a column to a table using SQLlite? Simply adding hte field to the define table statement throws an error. Using SQLlite I cannot add a Field. I get an error message: OperationalError: no such column: source_via.substrate No Joke Really? When I set migrate_enabled=True then the message changes to something like the table sourc_via does not exist Of course it does since I just added the column that I'm being told does not exist either to it. On top of all that I am back to the Rocket server locking up. It likes to do that so I have to use Task manager to close it. Could be that session.connect +SQLlite is not a good combinnation. --
Re: [web2py] Re: Looking for a way to combine auto-complete with adding a non-existing item.
Now that is impressive. I did get it to work but not with SQLFORM or SQLFORM.smartgrid so that was a large part of my problem. When renderred in the view created by SQLGRID (clicking the ADD+ button) I would get the SQLFORM and the person fields were displayed with it's own submit button. This looked like it could be a bonus however the Add New link did not work (doesn't really need to if the form is already rendered) and information was not saved to the database. Confirmed this by visiting the grid again. I could see all of the users you added before. Looks like I'll drop use of SQLFORM in favor of this widget.Thank you for the sample app. It made a big difference. Regards, Bill --

Whether or not it is the source of appadmin not storing values is yet to be determined. After my columns were successfully added, values were set to null automatically of course. When I tried using appadmin to change the values (note this has nothing to do with the widget except the widget happens to be rendered on the edit or create page) the values do not update. Not saying it's the widget, I just don't know. Regards, Bill --
[web2py] Re: How to add a column?
in the normal way (i.e. a new Field(), with of course nothing set to
prevent migrations, such as migrate=False in the table def, migrate=False,
fake_migrate=False, migrate_enabled=False, fake_migrate_all=True in the
DAL, etc).
There absolutely no problem on doing that.
With the first error it seems that you added a Field but you didn't let the
table to migrate (i.e. web2py expected a column to be there already, and it
didn't find that)
The second instead seems to point to a table that existed in the db and was
dropped manually (assuming that you defined the table 'source_via' and
you're trying to access it as 'source_via', your error seems like a typo
'sourc_via' without the 'e').
PS: let me explain for others stumbling on this post on how migrations
work. database/*.table files are there to hold the situation on the
current database status.
With default settings (i.e., migrations turned on):
- the database/ folder holds all the table definitions as they are on the
database (the *.table files)
- whenever a request comes in and your db.py is executed, web2py spots
the differences between your .table files and the db.define_table()
statements (table files holds a photography on what was the model the
last time you executed db.py): if there are differencies (like a new
column, or a new table) the table is created on the db (check sql.log for
the statements used), and the .table file is updated to reflect what there
is in the db
What happens if you set migrate=False in the table definition ? the check
between the model in db.py and the .table file is skipped, and web2py
assumes that on the db the table reflect exactly what there is in the model
What happens if you set fake_migrate=True in the table definition ? web2py
assumes that on the db the table reflect exactly what there is in the
model, the .table files are recreated
What happens if you set fake_migrate_all=True in the DAL ? all .table files
are recreated, and web2py assumes that on the db the db tables are
reflecting the model.
What happens if you set migrate=False in the DAL? whatever table has no a
specific migrate parameter, the migrate=False is applied to every table
This kind of errors can happen only if you messed with this logic, e.g.
db.define_table('test', Field('test1'), migrate=True) #web2py create the
test table with the columns id and test1
then
db.define_table('test', Field('test1'), Field('test2'),
migrate=False,fake_migrate
=True) # web2py assumes that you created manually on the db the column
test2, and updates the .table file
then
db.define_table('test', Field('test1'), Field('test2')) # web2py sees no
change between the .table file and the model, but if there's not the column
on the db, when you try to use it you'll get the no such column error
then you delete the 'test' .table file manually, then
db.define_table('test', Field('test1'), Field('test2'), migrate=True) #web2py
assumes that the 'test' table is not on the db, because the corresponding
.table file is not there, so it tries to create it, and you get the error
table 'test' already exists on the db
or, you delete the 'test' .table file manually, and drop the table manually
on the db then
db.define_table('test', Field('test1'), migrate=False) #web2py assumes that
the table is already there, and when you try to use it you get the error
table 'test' does not exist
PS: session.connect(db) where db is SQLite is bad on every possible level.
Everytime a session changes you won't be able to write to the database
(SQLite by default doesn't allow simultaneous writes). session.connect(db)
is there to allow several web2py instances on different machines to NOT
have the sessions/ folder shared among them (or when you don't have write
access to the disk), and to be used with professional db (postgres,
mssql, mysql, oracle, etc)
Even better is to use memcached or redis for sessions, if you have those
available, or stick to cookie based sessions if your session data is little.
PS2: what's wrong with default file-based sessions anyway? Unless you have
100 concurrent requests AND ~40K separate sessions there is absolutely no
performance gain observable using other methods (db, redis, memcache,
cookies). The only added feature is being able to have separate web2py
instances on different servers without configuring a load balancer with
sticky sessions in front of those.

[web2py] Re: How many error tickets does a typical newbie handle?
while developing you should NOT use any of the migrate, fake_migrate, migrate_enabled, etc. Zero tickets in regards of db migrations (unless you do something weird like trying to change a column type from string to integer). The minute you go on production, deploy the app, hit the appadmin page (so all tables are created on your fresh production db), return to the db.py file and set migrate=False on the DAL. Next iteration, you develop another piece of app, freeze it, update your production, set migrate=True on the DAL, re-hit the appadmin page, return to db.py and set migrate=False. Next iteration, you screw some table (like converting a string column to an integer), the previous working method will NOT work (mostly because only you can know how to migrate that column (others call it fixturese.g. attempt a conversion and NULL all fields that doesn't cast to integers vs drop the column and readd and fill with default values, etc, etc, etc)). It's time to: - manually alter the database (optionally applying your fixtures) so that the db reflects your model - update your app - optional step: set fake_migrate_all=True in the DAL, hit the appadmin page (so .table files are recreated) and reset fake_migrate_all to False - set migrate=False on the DAL - use you app Didn't have ANY problems with this line of work in 2 years of deployment. --

please open a ticket about this. I will take care of it asap. On Thursday, 1 November 2012 15:54:53 UTC-5, Joe Barnhart wrote: This proposal solves a problem I have when formatting Field values. I created a custom Validator class which maps the value None into a string (such as N/A or NT), but the mapping was ignored because the current Field processing provides an early exit if the value of the Field is None, i.e. it never reaches the Validator object for formatting. Proposal: I propose creating a new keyword variable for Field objects, called map_none which is initialized to None for backwards compatibility: map_none = None, . . . self.map_none = map_none Next, we use the value of map_none as the return value for None from the formatter function: def formatter(self, value): requires = self.requires if value is None or not self.requires: return value or self.map_none Last, for symmetry, we alter the validator to replace any occurrence of map_none with None when processing items to go back into the database. In my case it will accept any entered value of NT and map it back into None when storing row data in the database. I would also use it to replace empty strings with None (which I prefer over empty strings in the database when values are not entered). def validate(self, value): if not self.requires: return ((value if value!=self.map_none else None), None) requires = self.requires if not isinstance(requires, (list, tuple)): requires = [requires] for validator in requires: (value, error) = validator(value) if error: return (value, error) return ((value if value!=self.map_none else None), None) This approach allows any mapping of None into an object of the user's choosing, and provides the mapping in a consistent and bi-directional manner. It preserves all existing behavior of Validators. The only cost is an additional variable carried in Field objects and the time expended on the trivial if tests to map the value. Any thoughts? -- Joe B. --

from DB too. In next versions I think need to add possibility to change
asterisk conf files using Asterisk AMI.
Asterisk qery sql db for check sip peers configuration, and save sip peers
state in sql table.
more information about realtime technology
http://www.voip-info.org/wiki/view/Asterisk+RealTime
in Asterisk need to add supporting res_config_mysql.so (MySQL RealTime
Configuration Driver)
(MySQL RealTime Configuration Driver)
-/etc/asterisk/extconfig.conf
sipusers = mysql,realtimesip, sip_conf_db
sippeers = mysql,realtimesip, sip_conf_db
extensions= mysql,realtimesip, realtime_ext3
add in file /etc/asterisk/extensions.conf
switch = Realtime/@extensions

[realtimesip]
dbhost = 127.0.0.1
dbname = webtopy
dbuser = testuser

in web2py models/db.py
db = DAL('mysql://testuser:topsecret@localhost:3306/webtopy')

I like asterisk.
How do you connect to asterisk from web2py?

Re: [web2py] Re: SQLFORM.smartgrid oncreate,ondelete not firing
Hi , So in this case how do I make sure it fires only when a new record is created for the child table in this case quotelines . Suppose if I have 2 different functions to be fired for the parent - oncreate and child - oncreate?

[web2py] Re: Import error with 2.2.1
It seems to be there, as I can import it from a normal python shell.
