[web2py] Ajax and table rows.
Hi all,
I'm trying to have a ajax callback function whenever I click a certain row.
I'd like that row to return the id of the record the row represents.
I'm at loss as to the middle argument for the ajax function. I checked the
function in the controller gets called but the argument is wrong.
I created a simple example so I could try and traceback the problem but I
think I'm doing something wrong.
This is my view:
{{extend 'layout.html'}}
table
tr class=row id=1 onclick=ajax('echo', ['id'], ':eval')
tdHello/tdtdWorld/td
/tr
tr class=row id=2 onclick=ajax('echo', ['id'], ':eval')
tdRow 2/tdtdNew world/td
/tr
/table
div id=target/div
And the following is my controller:
def one():
return dict()
def echo():
return jQuery('#target').html(%s); % request.vars.id
What am I doing wrong?

[web2py] problem with scheduler
Hi, I'm using web2py version 1.99.2 with the new scheduler. I have a scheduled function that is run once a day at the same time with this parameters: Start Time: 2011-11-10 01:30:00 Next Run Time: 2011-11-22 01:30:00 Stop Time:2020-01-01 00:00:00 Repeats:0 Period:86400seconds Timeout:3600seconds Times Run:... Last Run Time:... it happens that when something wrong happens (like crash or application is killed by kernel) when I restart the application the next run time is changed in the time part and the function is not performed at the same hour I planned... so I have to change by hand every time that it happens. Is it a strange behavior? thanks Manuele

Re: [web2py] Ajax and table rows.
The ['id'] middle arg of the ajax function works only with forms, and it
looks for the name attribute in form inputs for check its val().
your code needs to be something like this:

*script
$(document).ready(function () {
$('.row').click(funtion(){*
* ** ajax('echo?id=' + $(this).attr('id'), [], ':eval')** *
* });
});
/script*
table
tr class=row id=1
tdHello/tdtdWorld/td
/tr
tr class=row id=2
tdRow 2/tdtdNew world/td
/tr
/table
div id=target/div

def one():
return dict()
def echo():

What's inside now?
It must be a datetime.datetime() or a %Y-%m-%d %H:%M:%S date, not a
unix timestamp. Usually request.now fits, if you need to store current
date/time.
If you want to convert a timestamp into datetime object::
datetime.datetime.fromtimestamp(1321882700)
If you want to convert a date in a given format into a datetime:
datetime.datetime.strptime(string, format)
(Where format is the same accepted by ``strftime()``).
By the way: why does sqlite tries to parse the date with fixed format
instead of using ``datetime.datetime.strptime()``? Somebody can explain
that?

Re: [web2py] ValueError: need more than 1 value to unpack
Rahul, this is a str.split() error and it happens when there are less
pieces than str.split() expects.
An example:
fullname = 'John Smith'
(first_name, last_name) = fullname.split( )
print 'first:', first_name, '- last:', last_name
John - Smith
fullname = 'John'
(first_name, last_name) = fullname.split( )
Traceback (most recent call last):
File pyshell#6, line 1, in module
(first_name, last_name) = fullname.split( )
ValueError: need more than 1 value to unpack
There weren't 2 parts in fullname. That's why the error occured.
Back to your problem, the same is happening with your updated_on
field. I'd make default=request.now on it.
BTW, try organize the traceback. It helps people helping you.

[web2py] Re: Can web2py do shared IP hosting
Dear Massimo, Thank you for your quick response. I heard your interview on FLOSS Weekly and that's how I discovered web2py. I guess I misread something. I thought I could download web2py and install it with a built-in web server ... Rocket I think was the name. (I haven't researched Rocket yet.) Are you saying that these features are addressed as part of the server environment and not a defined feature of web2py? (I've always had an admin doing this kind of detail work so I've never had to understand it in detail.) I should have been more clear about my computer environment ... my assumption was that I would be running web2py on my own dedicated server ... which is what I do now with my projects. My intention is to replace the server/framework I have now with one based on web2py but I want to be sure it has all the features I will need to grow. For example, I want to design all the new web sites to be mobile compatible using responsive page design, which scales smoothly for desktop, tablet and smart-phone screen sizes. Here's a page with many examples of this in production now: http://designmodo.com/responsive-design-examples/ Warmest regards, Rob:-]
Re: [web2py] field related to auth.user.id problem when user not logged in
But, according to your define_table()'s, these tables can only be managed (insert or update) with a logged user, or default contents will raise an excpetion because there's no logged user. The defaults won't raise an exception (as long as auth is defined prior to the table definitions), because auth.user_id simply returns None when the user is not logged in (i.e., it is not undefined). The same is true for auth.user -- it returns None when there is no logged in user (though auth.user.id will raise an exception because if auth.user is None, obviously it has no 'id' attribute).

Ok, now that this works seems I'm still in trouble.

expenses = db(db.expense.parent_table==request.args(0)).select()

Rocket I think was the name. (I haven't researched Rocket yet.) Are you saying that these features are addressed as part of the server environment and not a defined feature of web2py? (I've always had an admin doing this kind of detail work so I've never had to understand it in detail.) Rocket is primarily intended for development. You can use it in production as well, though for production it is generally recommended you use a more full-featured web server, like Apache. I should have been more clear about my computer environment ... my assumption was that I would be running web2py on my own dedicated server ... which is what I do now with my projects. My intention is to replace the server/framework I have now with one based on web2py but I want to be sure it has all the features I will need to grow. If you've got full control over your server, you might consider using one of web2py's setup scripts to set up Apache or nginx (http://code.google.com/p/web2py/source/browse/scripts/setup-web2py-ubuntu.sh, http://code.google.com/p/web2py/source/browse/scripts/setup-web2py-nginx-uwsgi-ubuntu.sh). For example, I want to design all the new web sites to be mobile compatible using responsive page design, which scales smoothly for desktop, tablet and smart-phone screen sizes. Here's a page with many examples of this in production now: http://designmodo.com/responsive-design-examples/ The responsive design stuff is mostly handled client side via CSS media queries and Javascript, so that will all work fine with web2py. In fact, the next web2py release (due any day now) will include a new responsive 'welcome' scaffolding app based on Skeleton (http://www.getskeleton.com). Here's an initial demo: http://tests.web2py.com/welcome/ (though a few tweaks have been made to the final version). web2py also includes some server-side code to enable detection of mobile clients and delivery of alternative output. request.user_agent() gives you the user agent details, and request.user_agent().is_mobile tells you if it's a mobile client. Also, adding the @mobilize decorator to a function changes its view file from function.html to function.mobile.html when the request is from a mobile client. Anthony
Re: [web2py] Can web2py do shared IP hosting
Hi Rob, what webserver are you running right now? Kenneth Hi Phyo, Thanks for your response. My current environment is a dedicated server machine with a single web server which servers multiple web separate sites on sub-domains and dedicated IP addresses. The configuration at this level has always been handled by an administrator so I know less about it than I should. I'm trying to figure out if web2py can replace my existing system and provide all the features and flexibility that I will need going forward. Thanks again for your help. Peace, Rob:-]

[web2py] Re: gevent helper script integration with web2py
I ended up creating a virtualenv with the needed libraries within the modules folder and using the virtualenv python binary to execute the script within the web2py environment. I feel it's a bit hackish, but I'll clean it up in the future. What I do find interesting is that the script is actually executing in the models folder for things like import lookups and for opening files. The db (the DAL connection to the database) is only available as a global in the main() function of my script, I have to explicitly pass it around otherwise. Is this the way it works (both executing within the models folder, and the scope of the globals)?

[web2py] update_record() for DB's without an auto_increment field

I seem to be having a problem using DAL with legacy databases, namely those
without an existing AUTO_INCREMENT field:
db.define_table('manufactured_by',
Field('product', 'string'),
Field('brand', 'string'),

rset.update(brand=Dior)
Whereas the update_record() function throws an error -- KeyError:

row = rset.select().first()
row.update_record(brand=Fendi)
Same for update_or_insert() which relies on calling update_record(). Tried
with SQLite and MySQL backends. Is there any way to make those work?
Many thanks!

[web2py] import_from_csv_file problem with reference fields with 1.99.2?
In my application which is hosted on GAE I have backup/restore functions which use export_to_csv_file/import_from_csv_file. While this is not a practical backup/restore for GAE (restore would take far too long and timeout, so for this purpose I use GAE bulk loader tool), I have used it in the past to backup from GAE and restore to test environment. This used to work fine. However, with 1.99.2, reference fields in all the tables are left with the GAE values rather than being replaced with the new ID's of the corresponding records. Both export and import were done by 1.99.2 and the import otherwise works - there is no reported failure. Is this related to issues 351 or 513 in code.google.com/p/web2py?

The 'links' argument can be a list of lambdas that take the 'row' object as an argument, or a list of dictionaries with keys 'header' (for the column header) and 'body' for the lambda function (links that are dictionaries get their own column; otherwise, they get added to the last column with the view/edit/delete buttons). Perhaps you could use this to display virtual fields associated with the row.

[web2py] DAL's virtual fields
In the Official web2py Book I read about DAL's Virtual Fields that:
...each method of the class that takes a single argument (self) is a new
virtual field.
It seems however that any function of the class is treated as a new field
and called to calculate its value. As an example I added a support function
to the class:
class MyVirtualFields(object):
def total_price(self):
return self.support_function(self.item.unit_price,
self.item.quantity)
def support_function(self, price, quantity):
return price*quantity
And on row retrieval I receive the following exception:
TypeError: support_function() takes exactly 3 arguments (1 given)
As a workaround I can add default values for arguments and additional
checks in the support function. But I wonder what is the proper way to add
a non-field function to the class?
Thank you!

[web2py] Re: update_record() for DB's without an auto_increment field
That is one the restrictions when working with keyed tables.
Here are the original notes (see #5):
1) primarykey is a list of the field names that make up the primary
key
2) all primarykey fields will have NOT NULL set even if not specified
3) references are to other keyed tables only
4) references must use tablename.fieldname format, as shown above
5) update_record function is not available
6) web2py rev.1354 (or higher) has appadmin support for keyed tables.
It should be in the book but I don't see it...

#/Applications/GoogleAppEngineLauncher.app/Contents/Resources/GoogleAppEngine-default.bundle/Contents/Resources/google_appengine/google/appengine/tools/dev_appserver_login.py
#
#line 260 in LoginCGI(), add:
#
# #hack for bulk loader
# redirect_url = continue_url
# output_headers.append(SetUserInfoCookie('t...@example.com', True))
note that the line number about is at least one GAE version out of date
because i am behind by at least 1 GAE version due to other bugs with GAE
SDK/web2py in the latest.
[web2py] setting db table for SQLFORM from an argument
I'm trying to abstract several content creation controllers into one controller. I want to use request.args[0] to set the db table in which the new row will be created. So far I've got this: def add(): the_table = request.args[0] tb = db.%s % the_table form = SQLFORM(tb) but I'm getting an error that str object does not have the attribute 'writeable'. It seems like SQLFORM is treating 'tb' as a string object rather than taking the string's content as an argument. Am I missing something? Is there a better way to do this? Thanks, Ian

[web2py] Re: Problem with using .as_list()
What do you mean does not work properly? What do you see, what do you get? On Nov 21, 6:12 pm, villas villa...@gmail.com wrote: Why doesn't the as_list() seem to work when fields have been specified? Try this: db(db.table.id == 1).select().as_list() #works fine Now this:db(db.table.id == 1).select(db.table.id,db.table.x).as_list() #doesn't work properly with fields Am i missing something? I think as_dict() is the same.

As Bruno suggested: def add(): tablename = request.args[0] if not tablename in db.tables(): error() # or other set of allowed tables. form = SQLFORM(db[tablename]) On Nov 21, 8:49 pm, monotasker scotti...@gmail.com wrote: I'm trying to abstract several content creation controllers into one controller.

[web2py] Re: SQLForm.grid - How do I use it properly?
I am bit lost in this thread. Can you summarize the issue? On Nov 21, 7:55 pm, villas villa...@gmail.com wrote: Yes, that's a good idea and it does seem to work. On the downside, I have a huge number of fields and I think the query will still fetch them all. Also I have to make a very long list of field.readable = False. So, if a better solution appears, I would be very grateful. However, in any case, I really do appreciate your assistance. Thank you and best regards, David
Re: [web2py] setting db table for SQLFORM from an argument
db[the_table] works! Thanks Bruno.

Thanks Massimo. I hadn't included the error handling bit.
[web2py] Insert references in a record
Hello,
I'm having difficulty getting inserts to work with tables that have
references and I'm sure its something stupid I'm doing wrong.
Hopefully you guys can point me in the right direction.
I have the following 2 tables.
db.define_table('event_users',
Field('event', 'reference events'),
Field('user_name', 'reference auth_user'),
Field('goal', 'double'),
Field('last_entry', 'date'),
format = lambda row: %s - %s % (row.event.name,
row.user_name.first_name))
db.define_table('entries',
Field('user', 'reference event_users'),
Field('date_entered', 'date'),
Field('value', 'double'),
format='%(user)s %(date_entered)s')
I'm trying to insert a record into the entries table. I have the
following SQLFORM to generate the view and then try to pre-populate
date_entered and user. User is calculated and is equal to Reference
form = SQLFORM(db.entries)
form.date_entered = date.today()
form.user = user
if form.process().accepted:
But the form won't submit. When I debug it through Eclipse it says
lazyT: value not in database
Any suggestions?
thanks
Adrian
[web2py] Re: Insert references in a record
I am pretty sure the error is not the code you showed us. You are
somwhere assigning something to =T(...) where it expects a string.

Re: [web2py] SQLForm.grid - How do I use it properly?
try this :
,links = [lambda row:
A(
SPAN(_class='icon magnifier')
,'View Post'
,_class='button',_title='View Post'
,_href=URL(args=[view, db.person, row.id])
)
]

Hi Johann,
That is correct but I just wanted to know if I can change the
existing functionality for SQLForm.grid View button. To be precise -
here is an example of what I am trying to do.
Example:
The default builtin View button on SQLForm.grid has label View,
now how can I change its label to say View Post. Note, here I do not
intend to over-ride the existing controller(function) that
SQLForm.grid's View provides but just change its label. How can we
achieve this? I hope you get what I am doing here :)
Again - If someone could post the complete syntax for SQLForm.grid(All
possible parameters ). It would be really helpful. Thanks
Thanks and Regards, Rahul

Hi Johan, All,
Sorry but I am not able to get it. With your code above I get
an invalid controller
You are not supposed to use that code exactly as it is. You must adapt
it
for your circumstances:
links = [lambda row:
A('Edit',_href=URL(controller,edit,args=[update, tablename, a.id
]))
Replace controller with your controller e.g. 'default'
Replace 'edit' with your function in the controller referred to.
