[web2py] Update record in session
Is is possible to hold a record in session, something like: id = db.transactions.insert() session.transaction = db.transactions[id] and directly update_record the session.transaction, session.transaction.update_record(x=y)# This throws KeyError: 'update_record' or is it necessary to reselect the record each time the controller is called? if session.transaction: transaction=db.transaction[session.transaction.id] transaction.update_record(x=y)
[web2py] Re: custom.widget manipulation with checkboxes
Got the solution myself.
The right code is:

db((db.mytable.id==id).select(db.mytable.myfield).first() #updated
form.custom.widget['myfield']._postprocessing()

[web2py] Re: Update record in session
session is not the database. you can save the transactionid into the session and update the db in the controller. e.g. id = db.transactions.insert() session.transaction = id db(db.transactions.id == session.transaction).update(x=y) or you can manage transaction record in the session and update the db at the last step e.g. from gluon.storage import Storage id = db.transaction.insert() session.transaction = Storage() session.transaction.id = id session.transaction.otherfield = x . session.transaction.otherfield = y db(db.transaction.id == session.transaction.id).update(otherfield = session.transaction.otherfield) In any case, if you save something to session and you want that change saved into the database, you have to do a specific update using db(...).update()

[web2py] Re: Advice please: best way to count records?
The two methods you described are the only available methods to achieve such a thing. If you have 100 records returned and you want to paginate by 20 (5 pages), then the difference between one method or the other is negligible. If you have 1000 records returned and you want to paginate by 20 (50 pages), then the best method is fire a "count" and a separated limitby for retrieving the records. Remember you can fire a db(query).count() and cache that: the record count will be fetched one time only and from then on from the cache and the db will be hitted only by the limitby query. e.g. total = db(db.pages.active==True).count(cache=(cache.ram,120)) records = db(db.pages.active==True).select(limitby=(0,20))
[web2py] Re: Update legacy table using primarykey failed

[web2py] Folder inside controller dosen't work.
Is that a bug or by design? I am using JSONRPC of web2py , i want to keep JSONRPC services int its own subfolder so not mixed with controllers for html. But web2py is not allowing me to do so. Here is my web2py's conttrolelr path: /home/v3ss/web2py/applications/FastTract/controllers/ i want to put caselist.py (which is to deal with case table part of the project) inside services folder. so it should look like this : /home/v3ss/web2py/applications/FastTract/controllers/services/case.py All jsonRPC related services will go inside that folder. But when i tried to call : http://localhost:8000/FastTract/services/case/call/jsonrpc?nocache=1328793441550 invalid controller (services/case) What can i do? I believe code folder organisation is very important feature for Large complex systems.

The point is just that you need to pass in the db instance, either via an __init__ method of a class, or simply as an argument to your function.

If you set unique=True and notnull=True and then try to insert non-unique
or null values, respectively, it is supposed to throw an exception. If you
want to enter non-unique or null values, then don't set those arguments to
true. On the other hand, if you want to catch those errors more gracefully
during form submission, then you should use field validators. For
unique=True, use the IS_NOT_IN_DB validator, and for notnull=True, use the
IS_NOT_EMPTY validator. Note, if you don't specify any "requires" attribute
for the field, these validators should be added automatically. However, the
validators will only be used for form submissions when using SQLFORM or
when using the validate_and_insert() method for making inserts. If you are
doing manual inserts via the insert() method, the validators won't have any
effect.
Another option is to put your insert in a try...except, and catch the
IntegrityError.

If it is OK for the images to be publicly accessible, you could upload them
to the /static folder instead of /uploads -- in that case, once initially
loaded by the browser, the browser should cache them for subsequent
displays. Otherwise, if you are using the download() function to download
from the /uploads folder, you could add some logic to the download function
to have it set the response headers to tell the browser to cache the images
(i.e., same as static files) -- you could use a URL arg or var as a flag to
tell the download function to do that.
> Problem3:

Use the IS_LENGTH validator:
Field('image', 'upload', requires=IS_LENGTH(524288))
The first argument to IS_LENGTH is the maximum file size in bytes (512KB =
524288 bytes). You can also specify a minimum size as the second argument
if needed (default is 0).

Would another option be to cache the entire select and pull out the needed records based on the "page" requested: records = db(db.pages.active==True).select(cache=(cache.ram, 300)) I suppose that wouldn't be a good idea if there are likely to be enough records and/or enough simultaneous users with different cached queries to start pushing the limits on available ram, but may be workable for moderate loads.

[web2py] best way to fetch data from multiple tables?
I have to query 3 tables which contains large number of data I have to come up with report which displays Employee Firstname, Lastname, Manager's FirstName, Manager's Lastname and Organisation name. Table Structure/Details: 1. Employee table: which contains employee information(First name, lastname), Organisation id and manager's id. 2. Manager Table: Which contains firstname, lastname etc. 3. Organisation table: which contains organisation's name. The process i follow is: 1. Fetch all the employees 1.a for each employee get the manager id 1.b For the manager id get the manager's firstname and lastname by querying the Manager table 1.c for each employee get the organisation id 1.d For each organisation id get the Organisation name by querying the Organisation table. When I try to fetch the records from 3 tables following the above approach, I get deadlineexceedederror as my request could not complete in 30 seconds time. Please suggest a better way to do this. Also what should i use which can improve performance and also get me the result in the 30 second timeframe.

I realized that db needs to be instantiated inside a module or passed explicitly as an arg, it is not possible to serialize it in to current. It works in the first request, but not for the subsequents. Another advice is that you never have to assign variables to current outside functions and methods Example. *Module.py* from gluon import current > request = current.request > > def myfunction(db): > if request.args... # HERE BE THE DRAGONS! > To work you need to do *Module.py* from gluon import current def myfunction(db): request = current.request if request.args # IT WORKS It happens because if you assign outside the function, it will be evaluated only at the first request, and for the subsequents, the request object will always be the same. -- Bruno Rocha [http://rochacbruno.com.br]

The main problem is the routing, web2py routes the second arg in url to the function, how would web2py knows if it has to be a function or a subfolder?

Not sure on the subfolder thing, but is it possible for you to put most of your code into modules and just use controllers as the gateway to your modules?

Re: [web2py] Re: How to replace this native query with DAL
To answer your question, happen_time is a column of cash_journal. The point of this call, is we allow people to cancel the site within 72 hours so any money they have made in that time if they cancel they do not get. IE: payback_types = ['s','p'], s = sponsor bonus, p = product bonus We use seconds to be more accurate so if you join at 5pm we count the 72 hours from 5pm now the full day etc..

[web2py] response.google_analytics_id
Dear ALL, How do i use response.google_analytics_id in menu.py : my google analytics id is Tracking ID: UA-29069723-1 ,
[web2py] Re: best way to fetch data from multiple tables?

I'm not sure. I think it's more like join then filter.
Something like below...
query = (db.person.id==db.dog.owner) & (db.person.name.like('Omi%'))
rows = db(query).select()

[web2py] response.google_analytics_id
Dear All, How can i use response.google_analytics_id in menu.py as i understand i need to have a script with my analytics id , but why is the response.google_analytics_id in menu.py and how can i use it ?
[web2py] Re: Script to generate schema (models) from mysql
Hi
I was trying to create model/db.py for RequestTracker mysql schema, and was
fail.
I found quite good plugin_legacymysql and fixed for my needs
- added few types
- remove 'SET' lines same as remarks
- mysql data types without params (like text,)
- import form_factory from sqlhtml
Please find fixed py attached.
Thanks
'''
Create the web2py code needed to access your mysql legacy db.
To make this work all the legacy tables you want to access need to have an "id" field.
This plugin needs:
mysql
mysqldump
installed and globally available.
Under Windows you will probably need to add the mysql executable directory to the PATH variable,
you will also need to modify mysql to mysql.exe and mysqldump to mysqldump.exe below.
Just guessing here :)
Access your tables with:
legacy_db(legacy_db.mytable.id>0).select()
If the script crashes this is might be due to that fact that the data_type_map dictionary below is incomplete.
Please complete it, improve it and continue.

[web2py] Re: Modules: how to access db
based on advice on the group long ago i am using a pattern like this: in db.py: current.myapp = Storage() current.myapp.db = db #after db is inited then in my module refrencing db as: current.myapp.db i'm using this on GAE and it has been working like a champ. the key is to add the just defined version of the db variable to current on each request, and not cache it as a static variable. remember that db changes on each request (new connection from the pool, different default and requests for table fields etc), so you can't keep db a static module variable or a static global variable and have it work for more then 1 request.

[web2py] Re: how to deploy web2py not in the apache root (help with url rewriting)
If you have just one application all you need to do is set the web2py WSGI
script alias and serve files from the web2py folder excluding admin parts.
WSGIDaemonProcess web2py display-name=%{GROUP}
WSGIProcessGroup web2py
WSGIScriptAlias /prefix /var/www/web2py/wsgihandler.py
Options +FollowSymLinks
AllowOverride None
Order Allow,Deny
Deny from all
Allow from all
AliasMatch ^/prefix/([^/]+)/static/(.*)
/var/www/web2py/applications/$1/static/$2
Order Allow,Deny
Allow from all
Deny from all
Deny from all
Then set path prefix and the default application in your web2py/routes.py
file:
routers = dict(
# base router
BASE = dict(
default_application = "app",
path_prefix = "prefix",
),
)
As a result you will get "domain/prefix" pointing to the default
application "app".

inserted into the page and allows tracking from google analytics, without
any additional code.

[web2py] Re: Update legacy table using primarykey failed
uhm, this is the relevant part for the form I was asking for
for the "session" , just put {{=BEAUTIFY(session)}} into the template and
watch the keys
Here the strange part is that it seems that employee code is not an integer
as defined into the model but a decimal. I don't know if this is the actual
problem, but it is different from the "normal" way.
Waiting for the session data to see if formkey is different or equal, that
is the problem I was addressing in the previous message.
Re: [web2py] Re: Advice please: best way to count records?
I don't think a count can be cached that way, but since it just returns a
number, it can be cached in the usual way instead:
count = cache.ram('count', lambda: db(query).count(), time_expire=60)

I just check gluon/dal.py and if it is the count() code location it's not
have cache argument... Also I notice that there seems to have many

generic function reused everywhere, it would be more DRY...

[web2py] markdown
Markdown display using the imported WIKI function shifts text down by
about 1/2em (one half of a line). This is very annoying in a table
which no longer lines up vertically. The markdown rendered text
column shows up below the other columns across a row. This just looks
bad. Is there any reason for the extra vertical padding before the
text? It is not part of the markdown "specification" from Gruber.
Negative padding on the top doesn't fix this. Even -1px causes most
the the rows to display nothing in the column at all, probably because
of a slight collision with the bottom of the preceding row.
G. All I want is proper line breaks between paragraphs to display
and this appeared to be the easiest way to do it without parsing all
of the text and inserting tags at every hard return.
There is also a minor bug in the __init__ function for markdown where
the WIKI function is defined:
from markdown2 import *
from gluon.html import XML
def WIKI(text, encoding="utf8", safe_mode='escape', html4tags=False,
**attributes):
if not text:
test = ''
if attributes.has_key('extras'):
extras = attributes['extras']
del attributes['extras']
else:
extras=None
text = text.decode(encoding,'replace')
return XML(markdown(text,extras=extras,
safe_mode=safe_mode, html4tags=html4tags)\
.encode(encoding,'xmlcharrefreplace'),**attributes)
It's pretty clear that it should be if not text: text = ''
[web2py] Re: maybe minor bug or just documentation
Then why did web2py fail with a run time error? Or why wasn't the run
time error trapped? Maybe because I had requires on the same table
for a different constraint?
It doesn't look good when visitors to your site see the web2py error
ticket page. Adding the explicit constraint prevented that. Without
the explicit constraint, attempting to add a duplicate category
produced an error because postgresql threw the error (correctly--it
was doing what is was told to do by rejecting a duplicate).
Should be easy to repro.
Thanks, Anthony.

Those lines are printed when UWSGI_ROUTING c constant is defined and the
only way to do that is passing -DUWSGI_ROUTING to the makefile. The funny
thing is that uWSGI routing has been only really added in 1.1 (still
unreleased) so i really do not know why you have that flag turned on :)

[web2py] DAL speed - an idea
One of my controllers need to go through a lot of records to provide a
meaningful answer -- as in, 60k records.
Just loading them from the database takes about 100ms
(db.executesql("select * from table order by id;")); Doing the same through
DAL takes over 6 seconds. I realize that the DAL does do a lot of
additional work, which in general is helpful -- but I can do without all
the parsing / Rows() generation for this.
What do people here think about adding a db.rawselect(...), which is a slim
rapper for db.executesql(db._select()) that wraps everything with a
named tuple? It solves most of the speed problem when it is needed, but
still maintains a lot of the features of the SQL DAL processing.
Re: [web2py] DAL speed - an idea
You mean using the generated SQL command to fire execute_sql and returns as
a named tuple?
>>> db(db.query).raw_select()
it is the same as doing
command = db(db.query)._select()
result = db.execute_sql(command)

What I see you are trying to say is that by keeping the code secret one gains a temporary advantage over the competition. That might be true. But this is the way of thinking coming from the proprietary software philosophy. How much will I loose by making the software free? If this is your line of thinking, then maybe writing free software is not what you want to do. Because at the core of the free software movement is a believe, that sharing the code would make the world better. Free software is not here to make us rich. Is not here to make our software easy to (ab)use by business. It is here to preserve out freedoms. It represent an ethical view that sharing knowledge is more important than making money. If you don't agree with that, then the free software is probably not for you. Everyone writing free software should understand that the old business models of proprietary software based on secrecy doesn't apply here. The value is in the collaborative effort to improve the shared code. It shouldn't bother you when somebody else builds on your code and gets ahead of you in terms of features, because this is what you wanted when you decided to write the free software! Instead of complaining that this puts you out of the business you should rather seek for opportunities to collaborate and write more code together which would be good for the business too. And if you want to compete, compete in solving new problems (not the ones that have been already solved, there is no need to duplicate the works of others) and charge your customers for doing that. Now, don't get me wrong. I admit it is not as easy to build a business around the free software as it is in case of proprietary software. But it is not impossible or even especially hard. And is much more fun. This is why we shouldn't give up trying new ways just because they are different to what we know from the proprietary world. On the rise of cloud platforms I see future for the AGPL too.
[web2py] Re: markdown
Here is an easier solution:
{{=XML(joke.joke.joketext.replace('\n',''),
sanitize=True)}}
{{=joke.auth_user.first_name}}
{{=joke.auth_user.last_name}}
All I really wanted. Didn't need the rest of markdown or markmin.
BTW, MARKMIN also pads the top of the text. Curious why this is so
but got what I wanted: just use Python.

Re: [web2py] Re: [w2py-dev] Re: Movuca - Social CMS beta 0.1
I can see your point even though I don't 100% agree with it. I write most of my code opensource, however I also have been writing software for a living for around 14 years so sometimes we don't have the choice between open and closed source. We also can't expect only people interested in free software development to use our software. Considering as you just said the software is there for others to use and if they add more features faster then you and don't give you the features you also can't get upset. Also sharing code and sharing knowledge are not always one and the same. The freedom in software also comes the freedom of choice, to either give back or not, that is why a lot of people prefer the BSD thinking over the GPL thinking. BSD = Doesn't care if someone makes money off their code or not, they just want people using their code. They also have the choice to release their code or not. GPL = Doesn't want anyone making money off their code and forces people to recommit their code. This is good because everyone gets the code, bad because you don't have a choice. I am more of a BSD thinker.

Re: [web2py] DAL speed - an idea
Yes, that is the basis of what I am suggesting.
There is not currently such a thing; there is something called 'select_raw'
implemented in the GoogleDataStore adapter, but not in anything else, and
it isn't exactly what I am proposing.
To elaborate:
Assume the table is defined as follows:
reftable = db.define_table('reftable', Field('a', string))
table = db.define_table('table', Field('b', reftable))
In my case, I need to pull all the records (60,000) from the database to
compute some aggregation which I cannot compute using sql. There are two
alternatives here:
r1 = db().select(table.ALL) # takes > 6 seconds
r2 = db.executesql(db._select(table.ALL)) # takes ~0.1sec
The records returned in the first instance are much richer; they have
record chasing (e.g. I can do r1[0].b.a to select through the foreign key),
they have methods like r1[0].update_record() and r1[0].delete_record(), and
other nice stuff.
However, for this use, I don't need the additional records, and I do need
the speed, so I would rather use r2. However, r2 is not a direct
replacement -- it doesn't have the column names. If I use
r3 = db.executesql(db._select(table.ALL), as_dict=True) # still takes
~0.1sec
I can do r3[0]['b'] but I cannot do r3[0].b; and it takes a lot more memory
than r2.
A suggestion: add another parameter, processor=... which, if available,
will be called with the db.connection.cursor, returning a function, through
which each routine will be passed; example
def named_tuple_process(name, description):
from collections import namedtuple
fields = ' '.join([x[0] for x in description])
return namedtuple(name, fields)
r4 = db.executesql(db._select(table.ALL), process=lambda x:
named_tuple_process('tablerec', x))
r4[0].b # will now work; not a full replacement, but good enough for many
uses.
In fact, you can do that externally -
r4 = db.executesql(db._select(table.ALL))
f = named_tuple_process('tablerec', db._adapter.cursor.description)
r4 = [f(x) for x in r4]
But this requires reaching into the internals of the db adapter.
Finally, I propose to define x.raw_select(*args) to do:
db.executesql(x._select(*args))
which would make this a relatively clean replacement.

Thank you the help.
So far, I found...

So this will fail. If it works for posgres and maybe problem with db2/

'integer' from define_table and always tried with string...

GPL do not forces anyone to recommit their code. It only says that if you make a GPL derivative, you have to offer a way to get the source code with the modification (only to your customers that received the software directly from you). You don't even need to publish it, just give it to your customers (of course, your customers can give the code to others). So, if you just use GPL for a web application, and you don't distribute that application, you don't have to give the code to anyone, you can keep it closed with all your "trade secrets". This will be the use case for most users of Movuca, so they wouldn't have to worry on republishing code. GPL only protect against anyone wishing to take open source code for free, closing it and sell binary only copies. That really hurts free software in this case.

Re: [web2py] DAL speed - an idea
I've been thinking about something like this as well. Instead of a separate
select_raw() method, maybe we can just add a raw=True|False argument to the
existing select() method. I like the namedtuple idea as well (I think some
adapters already provide that as an option -- e.g., psycopg2).

But I cant use Joomla to create a : *Bruno's joomla commercial platform* to compete with Joomla. I think if you are going to keep the code in your server the code is yours, but if you want to redistribute the platform, you have to contribute back to community.

[web2py] Odd hasattr(session, 'blah'). Don't understand it.
In an index function I do something like
session[request.controller].something = 'foo'
This raises a key error exception on the first visit to the controller
after restarting the browser. Session can't find the controller name,
so I can't add an attribute to it. So I need to initialize the
session, but not clobber it if already set.
After several hours this puzzling behavior emerged:
print session # request.controller not there, as expected.
# nothing but auth
print hasattr(session, str(request.controller)) # Prints True.
## Previous result not expected!! Why??
print request.controller in session # Prints False, as expected
session[request.controller] = {}
print hasattr(session, str(request.controller)) # Prints True
## As expected this time.
print request.controller in session # Prints True, as expected
print session[request.controller] # Prints {}, as expected
Can someone tell me why hasattr(session, str(request.controller))
returned true when request.controller was not an attribute of session?
Thanks,

There might be other reasons for the having the buttons on the left, but buttons on the right work fine with android if one can move right.

Re: [web2py] Odd hasattr(session, 'blah'). Don't understand it.
session is an Storage, Storages always return an attribute, defaults to
None.
You do not have to always access session objects by keys, you can do it by
attribute and it will always return an object, even if the object does not
exists.
examples
my_var = getattr(session, request.controller)
Even when you have nothing in session, it will return an object with value
"None"
>>> from gluon.storage import Storage
>>> session = Storage()
>>> my_var = getattr(session, "blablabla")
>>> my_var
>>> print my_var
None
>>> session.anything = "blah"
>>> print getattr(session, "anything")
blah
>>> print session.anything
blah
>>> print session["anything"]
blah
>>> print session.banana
None
>>> print session["ohohohoho"]
None
>>> print getattr(session, "jsdnfgkjsdnfjkds")
None
>>>

Re: [web2py] Re: [w2py-dev] Re: Movuca - Social CMS beta 0.1
For this case, LGPL3 or GPL3 are almost indistinguishable in this context (web app) AFAIK, LGPL3 is better if you want that subparts of Movuca being used/distributed in other contexts (i.e., with other closed source CMS, or with other open source software MIT/BSD licensed) With web2py it is more complicated to say if you can take it's source and create "Bruno's commercial framework". I guess neither with GPL nor with LGPL3 you could do that. What you can do is use web2py gluon libraries to build third-party closed-source apps, or use web2py to server closed source web-apps, but not a web2py propietary derivative.

I guess that still doesn't answer the "why" question. If it's OK to use open source code to create a commercial website (perhaps even a SaaS model that is essentially a "platform") without contributing code back to the community, then why is it not OK to use open source code to create a commercial "platform"? Why should one warrant code contribution back to the community but not the other? Neither the AGPL folks nor the BSD/MIT folks seem to think there should be a distinction (AGPL allows neither use case, and BSD/MIT allow both). Only GPL really makes the distinction, and the FSF folks seem to think that was simply an unfortunate oversight rather than a principled position (hence the AGPL). For what it's worth, most of the Django and Rails based CMSes are BSD/MIT licensed (as are Django and Rails themselves). I'm not sure what their experience has been getting contributions, or if they have in any way been hampered by commercial forks (or if there are even any commercial forks). Anthony
Re: [web2py] Re: [w2py-dev] Re: Movuca - Social CMS beta 0.1
I bet you'll get better luck in courts if you use a well-known licence. GPL has been written by lawyers and it has some enforcement jurisprudence right now.

You can generate friendly error pages -- see http://web2py.com/books/default/chapter/29/4#Routes-on-error. The error page can be a static file, or a dynamically generated page. In the latter case, it might be safer to have the error handler in a separate error handling application -- that way if the error happens to be in a model file of your main app, it won't prevent the error handler from being reached.

[web2py] Customize SQLFORM.grid
Hi,
In the old framework I would just query the database and loop through the
values manually creating the HTML table etc...
Which allows me to do something like this:
types = {
'bp': 'Product Bonus',
'sb': 'Sponsor Bonus',
}
for row in rows:
Type
types[row.type]
Is there a way to use SQLFORM.grid and tell it to display a dictionary
value based on the key stored in the database?

I think it's good for people to advocate for their license preferences.

I don't know what is meant by "a lot of people." But there are some statistics that seem to indicate a lot more people prefer the GPL. As of June 2009, the GPL licenses accounted for ~ 65% usage.

No. If this were anywhere close to true there would be mobs of angry kernel developers protesting the activities of companies like Red Hat and IBM, both companies making tons of money off GPL code.

Re: [web2py] Re: [w2py-dev] Re: Movuca - Social CMS beta 0.1
Making money off the code, meaning you can't go sell the code. With BSD code you can. I said a lot of people, I didn't say MORE people. With BSD there is also a lot of people using it that don't announce they are using the BSD based software.

[web2py] restricting the options in drop-down menu based on another drop-down menu value
Let's say the model has three tables, called country, cities and
customers that are defined like:
db.define_table('continents',
Field('name'),
)
db.define_table('countries',
Field('name'),
Field('continent', db.continents),
)
db.define_table('customers',
Field('name'),
Field('country', db.countries),
Field('continent', db.continents),
)
Now if I check the "Database Administration", how can I set up the
customers table such that when I am inserting a record in the
customers table, if I select a country, the continent the country is
in is automatically selected?
Under another scenario, imagine we first select the continent, then
the country and then enter the name of the customer, how can I set up
the model such that when the continent is selected, only the countries
in that particular continent are available to be selected?
I am imagining that the counties and continents in the customers table
and the countries table are drop-down menus.
Any help would be appreciated. Thanks! =)
Re: [web2py] restricting the options in drop-down menu based on another drop-down menu value
You have to do this with Javascript
http://176.34.12.39/welcome/en/static/js/location.js
That is how I am handling the situation where select a continent only the
countries for that continent show in the select box.
