[web2py] Re: Consuming a web2py web service in C#?
If you go to the web2py server admin app e.g. http://127.0.0.1:8000/admin and login you should see the name of the app containing the service and an errors link after the name. Click that and you will see the errors page and be able to see the stack trace. When running as a Python process you can put print statements in your controller to get an idea of what the parameters look like coming into the request. The output should go out on the terminal you ran python web2py.py from. Be sure to comment out the print statements before embedding in a web server such as apache with WSGI or you will get tickets from the print statement.
[web2py] How to make a constant for list of fields in select()?
To optimize a query I wanted to create a constant that represented the list of fields to select(). I ended up doing a join like I saw in the web2py source for SQLALL. Is this the best way? I tried a bunch of different other ways but none worked. item_summary_fields = ', '.join([str(field) for field in [db.item.id, db.item.title, db.item.image_thumb, db.item.currency, db.item.shipping_method, db.item.start_price, db.item.drops, db.item.duration, db.item.price_change, db.item.created_on]]) rows = db(db.item.id0).select(item_summary_fields)

[web2py] Strange autocomplete behaviour
Truncated model:
db.define_table('akb_doccenter',
Field('doc_nr', type='string', length=50,
requires=IS_NOT_IN_DB(db, 'doccenter.doc_nr')),
Field('location'))
db.akb_doccenter.doc_nr.widget =SQLFORM.widgets.autocomplete(
request, db.akb_doccenter.doc_nr, limitby=(0,20),min_length=2)
I use an autocomplete-widget to help the user to enter a unique doc_nr.
It works to a certain extend in the sense that it shows the doc_nr's in the
database except for those recently added. The database was prepopulated
with data from an older version. All the records entered after that will
not show up in the list shown by autocomplete. But if you search for it
they are there amongst the other data.
At first I thought creating an index on doc_nr would change this behaviour
but it didn't.
I have appended the screenshot. Compare that with the result of the query:
select doc_nr from akb_doccenter where doc_nr like 'wood5%'
wood591
wood5224
wood5225
Any idea how to fix this?

Johann

[web2py] Re: Subdomain Duplicates Content
Sorry if I didn't explain this well...
Imagine a scenario of a web company..
The company website is in the main app
The clients sites are in different apps like client1, client2, etc
In routes.py you redirect the domain to the respective app (ex.
client1.com - client1)
The problem is that from client1.com you still able to access other
clients through the link http://client1.com/client2/default/index
This is bad because client1 just want his website on his domain.
Did I make myself clear this time?

web2py (URL) isn't generating a domain *at all* in the URL unless you

[web2py] Re: How to implement background processes elegantly..
Here's an abstraction from my code. There may be better ways to do it,
but it works.
Let's say you wanted to start a miner to watch the system log...
from subprocess import *
from multiprocessing import Process, Queue
def doSomething(self, q):
p1 = Popen([ 'tail', '-f', '/var/log/messages'), stdout=PIPE)
p2 = Popen(['grep', '-i', 'foo'], stdin=p1.stdout, stdout=PIPE)
q.put(dict(pid=p1.pid))
def startDoSomething(self):
q = Queue()
p = Process(target=doSomething, args=(q,))
p.start()
db.settings.insert(pid=q.get()['pid'],
timestamp=datetime.datetime.now())
db.commit()
The reason I did it this way is that I need to control the start/stop
of this secondary process. There will only be one instance of it
running at any given time and special permissions are needed to access
the control functions.
--Nite
(Note, this example doesn't really make sense since we aren't doing
anything with the stdout from the grep command, but illustrates the
point of how to start a secondary process which was the purpose)

Hi,
For anyone else that might be wondering this issue,

And it did not work properly (it did feel a bit hack anyway).
One pretty bad solution to this issue is to use threading.Lock() in
every single db query / commit etc.
I will however look into multiprocessing and on the advice from

[web2py] Re: How to make a constant for list of fields in select()?
Use the python * operator to unpack the list, like this:
item_summary_fields = [db.item.id, db.item.title, db.item.image_thumb,
db.item.currency, db.item.shipping_method, db.item.start_price,
db.item.drops, db.item.duration, db.item.price_change, db.item.created_on]
rows = db(db.item.id0).select(*item_summary_fields)
In Python, if my_list is a list, *my_list unpacks the list. Similarly, if
my_dict is a dict, **my_dict unpacks it.
so, if we want to use orderby or groupby, we can use the dict unpacking like
this:
kw ={'orderby':'db.item.title'}
rows = db().select(*item_summary_fields,**kw)

The --pidfile option prevents start-stop-daemon from behaving like killall as mentioned in the Description section of the start-stop-daemon man page. This will allow start-stop-daemon to run python if it finds another copy of python on the system doing some other task. The --pid_filename option to web2py is needed to actually get the /var/run/web2py/web2py.pid file written otherwise the service web2py stop command or the init state change will fail to find the copy of python running web2py and kill it. Please use only the line 65 patch from above. I sent Massimo the correct patch file so he is looking at it. Ron

Re: [web2py] get last visited page
a href=javascript:void(history.go(-1))img src={{URL('static',

puts an image link that simulates the back button on the page. You could
convert it to button and use the jQuery alternative
Too much of a hack? The web2py framework is very good with history
integration.

Hi List, I was wondering why I see the css 'hidden' elements flash quickly on the page when the page is reloaded; then do the animation? For example when I submit an invalid form I see the hidden form error fields flash quickly then disappear then do the normal animation. I was wondering if maybe I did something to the default css that is causing this problem. Thanks. David.

Some elements are set to display: none, like the .flash and .hidden CSS classs. The reason for this is to prevent exactly what you are describing. You don't want those elements to be displayed before JavaScript has a chance to load. Once the page is fully loaded, then JavaScript makes these elements visible.
Re: [web2py] Re: Strange Flashing of Elements
Thanks Ross; So I suspect because I changed it to 'block' its flashing quickly; But I made the element a block so perhaps I have to write another div around the element to make it display correctly.

[web2py] Trouble updating with SQLFORM.factory and two tables
I am trying to make a user editor and running into trouble. I have the

stores a bunch of other information, using auth_user as the reference
between the two tables. I set my controller up like this:
def update():
id = request.vars.id or request.args(0) or error()
row = db((db.auth_user.id==db.auth_user_extended.id)
(db.auth_user.id==id)).select().first()
if row is None:
error()
form = SQLFORM.factory(db.auth_user, db.auth_user_extended
hidden: {'id': id}
)
form.vars.id = id
form.vars.auth_user = id
form.vars.username = row.auth_user.username
form.vars.first_name = row.auth_user.first_name
... etc ...
if form.accepts(request.vars, session, keepvalues=True):
# do the database update manually
However, my problem is that when submitting the form for an update, it fails
validation on username because value already in database. Am I doing
something wrong or does SQLFORM.factory not support updates? Thanks.

Re: [web2py] Trouble updating with SQLFORM.factory and two tables
This is the code I have: form = SQLFORM(db.auth_user, row.auth_user) form.append(SQLFORM(db.auth_user_extended, row.auth_user_extended)) My view requires that I manually build the form, and for some reason, when I look at the resulting form object via PDB, the form object has two items: gluon.html.TABLE object at 0 gluon.sqlhtml.SQLFORM object at 0 So when I call form.fields, it only returns the auth_user fields. I actually have to call form[1].fields to get auth_user_extended fields. Is this right?
Re: [web2py] Trouble updating with SQLFORM.factory and two tables
I've gotten much closer with this, however, I am still hitting a snag: One of the fields in my auth_user_extended is set to requires=IS_NOT_IN_DB(). And when form.accepts is called, I'm still getting a value already in database error.
[web2py] Re: Trouble updating with SQLFORM.factory and two tables
Is this the right comparison?
db.auth_user.id==db.auth_user_extended.id
In another post you have:
db.define_table('auth_user_extended',
Field('auth_user', db.auth_user),
Which means the relation is db.auth_user.id==db.auth_user_extended.auth_user

Yes, in http://web2py.com/book/default/chapter/09#Custom-Formats, the book says: Not all objects are pickleable, and not all pickled objects can be un- pickled. It is safe to stick to primitive Python objects and combinations of them. Objects that do not contain references to file streams or database connections are usually pickleable, but they can only be un-pickled in an environment where the classes of all pickled objects are already defined.

[web2py] Re: Dynamic Table Generation
The problem is that you are not saving your model (the table
definitions) and web2py starts from scratch on every request, so your
table is being created in the DB but web2py does not know about it.
That is what models do, they define the tables that are visible in
web2py.
Save that db.define_table... code in a file under the models folder,
then web2py will pick it up on all subsequent requests.

I was wondering how I can update 2 targets with reponse.js? I tried this response.js = 'web2py_component(url,target);web2py_component(other_url,other_target);' Seems only the first updated. Any ideas?

Hi everyone, I'm trying to make an app where a user can create its own

Project Name:
input name=projname /

input name=numfields /
br /Name of Fields:

Controller:
def config():
if request.vars:
proj_name = session.projname = request.vars.projname
num_fields= session.numfields= request.vars.numfields
nam_fields= session.namfields= request.vars.namfields
tblname = proj_name + _custom
response.flash = tblname
createtable(tblname)
return dict()
And in utils.py (inside models folder)
def createtable(tablename):
tbl = db.define_table(tablename,Field('a'))
But it doesn't work :(
The form works, I can get the variables by request.vars, but the table
is not created, how could I create dynamic tables??
If an user needs a table called project1 with 2 fields F1 and F2
and another user needs more different fields and table name, how could
I make this??
Thanks!
[web2py] db.table.insert() doesn't always validate data types? (Bug?)
I just found what might be a bug, when using db.table.insert(field = value)
it appears that the type of value isn't checked against the declared type of
field. So for example you can declare a field to be of the date type, but
then insert a record with a non-date value (at least in sqlite). I would
have expected the DAL to give an error when attempting to do something like
this, but it does not. However, when you then attempt to retrieve the
inserted record, an error does occur. If you separate the db insert from
the retrieval query and check in the database, you can see that invalid
data has been stored in the database.
Granted, if you're using forms validators then the data type conflict is
caught before the insert, but I thought it may be something that should be
pointed out - it isn't enough just to define data types in your model
expect web2py to always automatically enforce them.
Sample Code:
model.py
---
db.define_table('mytable',
Field('a_date_field', 'date')
)
controllers/default.py
def date_insert():
my_date = '05/24/2011' #note, this is a string not a date type. Should
have done datetime.strptime('05/24/2011','%m/%d/%Y) or date(2011,5,24)
record = db.mytable.insert(a_date_field = my_date)
results = db(db.mytable.id0).select()
return dict(results = results, record = record)

[web2py] Re: db.table.insert() doesn't always validate data types? (Bug?)
insert NEVER validates data types. FORMs and SQLFORMs validate input.
That is for speed.
You can call
r = db.table.validate_and_insert(**fields)
which returns r.id and r.errors

Re: [web2py] Re: Problem storing Storage objects in sessions
On May 24, 2011, at 5:58 PM, Anthony wrote: Yes, in http://web2py.com/book/default/chapter/09#Custom-Formats, the book says: Not all objects are pickleable, and not all pickled objects can be un-pickled. It is safe to stick to primitive Python objects and combinations of them. Objects that do not contain references to file streams or database connections are usually pickleable, but they can only be un-pickled in an environment where the classes of all pickled objects are already defined. The session Storage object itself is copied to a dictionary before pickling; it'd be reasonable to do that (and the equivalent for List) for Storage objects stored in the session.

Re: [web2py] Re: teaching email links to respect https
It might not be 100%. For example, on Nginx, you have to include this config: uwsgi_param UWSGI_SCHEME $scheme; But I still don't really understand why you need this.

Ah C, pointers and pointers to pointers for ** I used to like pointers in C but then I used to work on operating systems written in assembler during my early years in computers (70s, early 80s). Results in a different mindset.
