[web2py] How to insert only new items in db as fast as possible?
Hi I have the following table: db.define_table(products, Field(categoryID, db.productCategory, writable=False, readable=False, requires=IS_IN_DB(db, productCategory.id, productCategory.name) ), # reference field Field(productName, 'string',length=512, default=None), Field(description, 'text',default=None) ) - I have a list of (2) rows that might contain products and I would like to update my table. However some products might already be in the db while others are completely new. - I want to insert a row if it does not exist in the db (productName could play the role of the identifier here) is already there AND update a row in the case the product already exists in the DB I can do it pretty easily if I go item by item and check if it already exits in the db and then take the appropriate action (insert or update). What I am looking for is the most efficient way to do this (especially on GAE). thanks Miguel
[web2py] Re: custom validation, was: Re: IS_IN_DB referencing linked tables
Something like this in the controller:

select(db.event.eventtype,db.eventtype.eventtype,\
distinct=True,orderby=db.eventtype.eventtype)
a=[e.event.eventtype for e in eventtyperows]
b=[e.eventtype.eventtype for e in eventtyperows]

[web2py] split rows object in view.
I have the following code in a view:
ul
{{for row in rows:}}
li{{=row.facility}}/li
{{pass}}
/ul
The length of rows varies. I would like to split the list in two list
and display it in two columns instead of one. Is it possible to do
this in the view, or should the function return rows_1 and rows_2?
Kind regards,
Annet.
Re: [web2py] split rows object in view.
One way of solving this would be like this:
table
{{counter = 1}}
{{for row in rows:}}
{{if counter == 1:}}
trtd{{=row.facility}}/td
{{counter = 2}}
{{else:}}
td{{=row.facility}}/td/tr
{{counter = 1}}
{{pass}}
{{pass}}

Sorry for the lat reply. This is not a bug. This is a design issue and
tradeoff.
In fact there is a single virtualfields instance, the one you create
in:
db.test.virtualfields.append(TestLazy())
and not one instance per record. There are two reasons for this:
1) allows cumulative virtualfields (values that depends on previous
records)
2) save memory
You can replace your code
class TestLazy:
def lazy_test_field(self):
def lazy(self=self):
return self.test.name
return lazy
with
class TestLazy:
def lazy_test_field(self):
from copy import copy
def lazy(self=copy(self)):
return self.test.name
return lazy
and this would work as you expect. It is just that DAL leaves to you
the responsibility of making the copy and using the extra memory and
does not do it automatically because most of the cases it would be a
waste.

[web2py] cherokee problem with fastcgi and uWSGI
Hello, I'm trying to deploy web2py with cherokee on a fedora core 13 distro but I have several problems on it. I have read the slice web2py with Cherokee via uWSGI: a simple, easy guide that it could be found in web2pyslices but this guide is outdated because it seems to be done for an older cherokee version than 1.X.X. Current cherokee version is 1.0.8 Some things are not clear to me: 1.- For example where should be web2py: on /var/web2py or /var/www/ web2py. After reading the slice it seems that it should be on /var/ web2py. 2.- www-data user does not exist on fedora distro so where it says sudo chown -hR www-data\: /var/web2py I did sudo chown -hR root\: / var/web2py 3.- Its impossible to follow steps E throught G because options described there does not exists anymore in cherokee admin interface and I could not find other places where they could be. After trying to setup following more or less these steps when I point to http://localhost I always get the cherokee test page. The same problem with the steps that are on the online book to setup cherokee with fastcgi interface. The steps described there should be now a bit different to setup web2py with cherokee. I need some help, please. Thanks in advance!
[web2py] Making asynchronous request in web2py
Hi, I have this test case: 1. User registers in app. 2. App sends him greeting email (Welcome to so-and-so app). 3. App adds his email/name etc to mailing application (like Mailchimp) for auto-subscribing to newsletter. Now user expects steps 1 completion to take him to the next 'default/ index' page, and we don't want steps 2 and 3 to prevent completion of step 1. Is there a way to make step 2 and 3 complete independently, in a way that user's experience is not slowed down? Think of it as being equivalent of asynchronous ajax request, which doesn't wait for response before moving to the next piece of javascript. Any help on this? I know we should not create threads because web2py handles that for us (read in some older post long long ago). -- Adi

web frameworks design comparison
draft - please help me improve it focus on Model-View-Controller
frameworks
Controllers
In Rails class MyTestController ApplicationController def index
render_text Hello World end end
The name of the class has to match the name of the controller file.
Controllers
In Django from django.http import HttpResponse def index(request):
return HttpResponse(Hello World)
Django is explicit, you need to import all functions you use.
Controllers
In Cherrypy and TurboGears 1.0 import cherrypy class MyRoot:
@cherrypy.expose() def index(self): return Hello World
Cherrypy, Turbogears, and Pylons are also explicit. You need to import
all functions you want to use.
Controllers
In web2py def index(): return Hello World
web2py is similar to Rails. It imports for you all the web2py keyword.
Often, like in this case, you do not need any.
Get/Post requests
In Rails class MyTestController ApplicationController def index
render_text Hello +params[:who] end end
GET and POST variables are passed via params but other request
parameters (client ip for example) are passed via a different
mechanism.
Get/Post requests
In Django from django.http import HttpResponse def index(request):
return HttpResponse(Hello World %s % request.REQUEST[`who’])
Nice, simple. The request contains all the info. You can use .GET
or .POST instead of .REQUEST to be more specific.
Get/Post requests
In Cherrypy and TurboGears 1.0 import cherrypy class MyRoot:
@cherrypy.expose() def index(self,who): return Hello %s % who
GET and POST variables are passed via arguments of the action, but
other request parameters (client ip for example) are passed via a
different mechanism.
Get/Post requests
In web2py def index(): return Hello %s % request.vars.who
Similar to Django. All request data is in one place. You can
use .get_vars and .post_vars instead of .vars to be more specific.
Dispatching
In Rails URLhttp://hostname/MyTest/indexgetsmappedinto class
MyTestController ApplicationController def index render_text Hello
World end end
By default Rails does not allow running multiple apps without running
multiple copies of Rails, since the name of the app is not in the URL,
only the controller name (MyTest) and the action name (index) appear.
This can be changed by configuring routes.
Dispatching
In Django you need to edit url.py to map URLs into actions from
django.conf.urls.defaults import * urlpatterns = patterns(’’, (r’^index
$’, myapp.mycontroller.index), )
This is the equivalent of Rails’ routes and it requires using regular
expressions. There is no default. You need one entry in url.py for
every action.
Dispatching
In Cherrypy and TurboGears 1.0 import cherrypy class MyRoot:
@cherrypy.expose() def index(self,who): return Hello %s % who
Works very much like Rails and default mapping between URL and action
can be overwritten.
Dispatching
In web2py a URL likehttp://hostname/myapp/mycontroller/indexcalls
def index(): return Hello %s % request.vars.who
Similar to Rails and Charrypy but, by default the URL requires that
you specify the name of the app. This allows web2py to run multiple
apps without using routes. Web2py has its own version of routes that
supports two different syntaxes (with and without regular expression)
to overwrite the mapping and reverse mapping as well.
Calling Views
In Rails class MyTestController ApplicationController def index
@message=Hello World end end
It calls the default view (MyTest/index) which renders the page. The
variables marked by @ are global vars and are passed to the view.
Notice that if the view is not defined, this results in an error
message.
Calling Views
In Django from django.shortcuts import render_to_response def
index(request): return render_to_response(index.html,
{`message’:’Hello World’})
This is the short way of doing it in Django. You have to specify the
view name index.html since there is no default. Parameters are
passed via a dictionary. You get an error message if the view is not
defined. Notice that in Django a view is called a template and a
controller is called a

That's a strange error. Also, the syntax error on routes.py is on line 3,

My advice is to resolve the first error (Rocket) before worrying about the
routes error.

...which leaves the mystery of the routes syntax error.
I'd try it with the first three lines (two comments and blank line) removed,
and see what happens.
I'd also carefully check routes.py for invisible garbage characters, perhaps
from some word processor. Word's idea of a non-breaking space, for example.
If possible, zip the routes.py that you're uploading to GAE, and send me a copy.

Thinking about this I can't picture it. So do you render the parent- child form on the server? If so do you just render inputs for one child?

[web2py] Problem with crud.create and duplicate _formname
Hi, I think I found a problem (bug?) with crud.create and
form.custom.end:
I have the following model:
db.define_table('contents',
Field('name', 'string', required=True, notnull=True,
requires=IS_NOT_EMPTY()),
Field('ordering', 'integer', required=True,
requires=IS_NOT_EMPTY()),
Field('duration', 'integer', required=True,
requires=IS_NOT_EMPTY()),
Field('enabled', 'boolean', required=True),
Field('file', 'upload', required=True, requires=IS_NOT_EMPTY(),
autodelete=True)
)
The following controller:
def index():
form = crud.create(db.contents)
if form.accepts(request.vars):
response.flash='Inserted'
return dict(form=form)
and the serialization of form.custom.end is:
div class=hiddeninput name=_next type=hidden /input
name=_formkey type=hidden
value=b1b19180-5226-48da-8d26-da29ed904177 /input name=_formname
type=hidden value=contents_create //divdiv
class=hiddeninput name=_next type=hidden /input

value=b1b19180-5226-48da-8d26-da29ed904177 /input name=_formname
type=hidden value=contents/None //div/form
Notice the output is duplicated, specially _formname is repeated
with a value of contents/None, which makes the form not working.
Am I doing something wrong, or is this a bug?
Thanks very much.

Hi Massimo,

d[k] = v.isoformat().replace('T',' ')[:19]
elif not isinstance(v,(str,unicode,int,long,float,bool)):

if I understand correctly this code swallows NULL datetimes (and
probably other nulls), wouldn't be better to
have the following?

Now user expects steps 1 completion to take him to the next 'default/ index' page, and we don't want steps 2 and 3 to prevent completion of step 1.

Hello,
This works fine:
uwsgi --pythonpath /var/web2py --module wsgihandler -s /tmp/
we2py.sock --http :9090
If I point to localhost:9090 works ok and I see the welcome
application.
After that:
If I make a config.xml file as is described on
http://projects.unbit.it/uwsgi/wiki/Example
and I try with the virtualserver wizard to creat a uWSGI server I get
the following error:
/var/web2py/config.xml seems not to be a valid uWSGI xml configuration
file.
To get these step ok my config.xml file has to be the same as this:
uwsgi
pythonpath/var/web2py//pythonpath
app mountpoint=/
scriptwsgihandler/script
/app
/uwsgi
I fear that Cherokee has an outdated wizard, you should be able
to load every valid uWSGI xml file in it.
I will try to send a patch to the Cherokee team ASAP.
In the mean time do not use its wizard but simply add a remote source
specifying the address of the uWSGI server

[web2py] Re: Why Django Sucks (slides)
Where do you see the reference to web2py in the document. I did not see it. web2py allows for keyed tables (not on all supported database) and a key can be uuid. yes forms will not work well with it (at least I never tried) and web2py was designed with an integer ID in mind. This is not a fundamental design issue but more of a constraint that is imposed in various parts of the code. For example db.table[x] if x is integer assumes you want a record with id==x and if x is a string, it assumes you want the field object with that name. In retrospect assuming id was integer was a mistake (we copied Django and we should not have) and this is the main obstacle to port web2py DAL API on top of NoSQL databases. Eventually this constraint will be relaxed. Massimo On Sep 9, 4:07 pm, johntynan jgty...@gmail.com wrote: Nice mention of web2py about the application object.
