Re: [web2py] Re: How to use AJAX within a SQLFORM.grid 'add' form
Thanks Anthony. First, take grid out of BEAUTIFY -- not necessary. Thanks, done. Does db.t_dogs happen to have a field called name? If so, change the name of your extra input element to something other than name. No, it doesn't. Also, when typing in your input field, open the browser developer tools and see if (a) you get any JavaScript errors in the console No. and (b) an Ajax request gets sent to the server. Yes - but I knew that because I get a change in the display. It just isn't the change expected. To reiterate, when the Add form is displayed - in other words, while the grid is *not* displayed - typing in the form displays the whole grid in the Ajax target area. -- Blog: http://goo.gl/iOwv1w You can't live a perfect day without doing something for someone who will never be able to repay you. -- Resources: - http://web2py.com - http://web2py.com/book (Documentation) - http://github.com/web2py/web2py (Source code) - https://code.google.com/p/web2py/issues/list (Report Issues) --- You received this message because you are subscribed to the Google Groups web2py-users group.

Re: [web2py] Re: How to use AJAX within a SQLFORM.grid 'add' form
Really helpful, thanks Anthony.
One suggestion: Chapter 11 of the book, heading The ajax function, has
exactly the code I used (that's where I got it from):
form
input name=name onkeyup=ajax('echo', ['name'], 'target') /
/form
May I suggest that your comment about URLs be included in that
documentation?
Appreciate the help, thanks.

[web2py] Advice on building a search form
Hi All I'd like some advice on the best approach to building a search form. I don't think crud.search is right, but I'm not sure whether I should approach this using a SQLFORM or SQLFORM.factory or some other way. The model includes an 'activities' table that has a date column. There's also a 'customers' table, and the standard auth_user table. I want to build a form that has a date selector for 'from date', another for 'to date', a combo for 'user' (populated from auth_user) and a combo for 'customer' (populated from the customer table). The resulting query will be fed into a SQLFORM.grid, if that's important. Any pointers to a good way of doing this?

[web2py] Anyone using flake8 / pyflakes?
I've just started using flake8 from within vim. Flake8 checks code for PEP8 conformance and general errors, including undefined names. That means that running it when editing, say, a web2py controller, lots of warnings are given: /path/to/file.py|16| W802 undefined name 'session' There is an option to suppress reporting of specific errors/warnings, but that only applies to the PEP8 reporting, not the pyflakes reporting. Given the implicit import style of web2py (which I'm not complaining about), this results in lots of spurious errors when checking web2py code, spoiling an otherwise very useful tool. Has anyone hacked around with flake8 to suppress the undefined names warnings?

Re: [web2py] Cookies and Sessions

In other words, what problem are you trying to solve? That said, I'll try to offer some guidance. I suggest you ignore cookies altogether. Web2py uses them, but YOU don't have to. Think of the session as a temporary store to allow you to pass variables from one place to another. Given that HTTP[S] is a stateless protocol, it can only tell you that a user clicked on a link or typed a URL in the browser, not that they have put 25 widgets in their shopping cart (that's simplifying it a little, but hopefully you get the point). In your code, you can use the session to store the contents of the shopping cart (for example). So, when they click on 'buy', you might do something like: if session.cart: session.cart.append(dict(item='widget',q=2)) else: session.cart = [dict(item='widget',q=2)] Later, when they checkout, you can do: for orderline in session.cart: process(orderline['item'],orderline['q']) There are neater ways to do this, particularly if you use Storage() objects rather than dictionaries, but the principle is that you can use the session to give variables persistence between requests. *1. What can you store in them? * In a session: anything than can be pickled (notable NOT user-defined objects). *2. When are they deleted?* When you do session.forget() *3.

[web2py] Stopping a timer from an Ajax call (Clienttools)
I'm using clienttools.py to put a timer on a page; the timer calls a controller function (imaginatively called 'tick') every second, which in turn updates a div on the page via Ajax. So far, so good. I want the 'tick' controller function to be able to stop/disable the timer under certain circumstances. I can do this interactively from a link that results in the whole page being refreshed, but not from the tick function; I think that's because the clienttools page.ready() function is only called on initial page load, not from when an Ajax update completes. Bits of code: to set up the timer: callback = js.call_function(tick) page.ready(js.timer(callback,1000)) ...which works. Calling this from 'tick': page.ready(js.stop_timer(request.var.timer_id)) ...doesn't stop the timer (the request.vars.timer_id is valid). Is there a way of stopping the js timer from an Ajax call? Alternatively, is there a better way of calling 'tick' to update a page every second? -- You can have everything in life you want if you help enough other people get what they want - Zig Ziglar.

Doh, you're right. All the datetime api on fields are extracting, not
converting the actual value
Yes, and I've also found that, with Sqlite at least, web2py doesn't
carry out datetime arithmetic correctly within the DAL (not entirely
Web2py's fault).
Rather than have another field in the table for duration, which could
easily get out of sync with start/stop times, I created a view instead:
CREATE VIEW v_durations as select
id,f_date,f_start,f_end,strftime('%s',t_periods.f_end)-strftime('%s',t_periods.f_start)
as f_duration,f_category,f_task,f_user from t_periods;
I use that view, rather than the t_periods table, for reporting. It's
defined in the model as migrate=false, and it works really well. If I move
to another database (probably MySQL for production), I only need to create
one new view. This way, edits to the table are no problem, and the
duration from the view is always correct.

[web2py] Documentation suggestion
If something like this has already been suggested, please point me at the earlier discussion. I've read the Web2py manual (and bought three of them) since v1, and the quality of both web2py and the manual has improved hugely. To my mind, however, the manual tries to fulfil two roles currently: it is a howto manual with lots of developed examples, and it is a reference manual. I think the two functions should be split to two documents. Rationale: the current format requires that the reference material be spread throughout the book. A simple example: look up the 'URL' helper function. The helper functions are listed in Views chapter, and indeed the URL function is included in the list under HTML helpers. However, it is actually defined in the previous chapter (Core). The tutorial nature of the manual requires it be discussed in core, but the reference nature of the manual suggests it should be under HTML helpers. This isn't the only example. It also isn't a criticism: as a single document, the manual is about as good as it could be. My question is simply: is it time to split it up? -- You can have everything in life you want if you help enough other people get what they want - Zig Ziglar. Who did you help today?

for every period, duration is calculated as:
duration = db.periods.end_time.seconds() -
db.periods.start_time.seconds()
This is wrong.
I reworked my data model so that the period start and stop fields were of
type datetime. I then found the flaw in your logic above: the seconds()
method returns the value of the seconds part of the datetime rather than
the number of seconds of the duration.
You can see this below. For one row (id==257), these are the values:
Row {'f_start': datetime.datetime(2012, 3, 25, 18, 18, 54), 'f_end':
datetime.datetime(2012, 3, 25, 18, 19, 1)}
So, start at 18:18:54 today, stop at 18:19:01, so the duration should be 6
seconds. However:
duration = db.t_periods.f_end.seconds() -
db.t_periods.f_start.seconds()
result = db(db.t_periods.id==257).select(db.t_periods.id,duration)
for r in result:
... print r
...
Row {'t_periods': Row {'update_record': function lambda at
0xa15e1b4, 't_periods_archive': gluon.dal.Set object at 0xa0dcf8c,
0xa15e1b4'id': 257, 'delete_record': function lambda at 0xa15e10c},
0xa15e1b4'_extra': Row {(web2py_extract('second',t_periods.f_end) -
0xa15e1b4web2py_extract('second',t_periods.f_start)): -53}}
...giving -53 seconds. In other words, it is the difference in the value
of seconds rather than the duration.

Re: [web2py] Re: DAL or SQL?
Perhaps you could add the seconds as a virtual lazy field.
That sounds worth investigating, thanks.
We shall come to an agreement when you explain plainly what is your real
model... it seems that your start and end columns are time and not
datetime... Time fields don't have a seconds() method, only datetime!
In my original posting, I said: the periods table has id, date,
start_time, end_time (and other fields). I suppose I assumed that the
presence of a 'date' field implied that the *_time fields were indeed of
type time, but I'm sorry if that wasn't clear. For clarity:
db.define_table('t_periods',
Field('f_date', type='date',
label=T('Date')),
Field('f_period_start', type='time',
label=T('Period Start')),
Field('f_period_end', type='time',
label=T('Period End')),

[web2py] Bug(?) using list:string in 1.99.7
My application has broken moving from 1.99.4 to 1.99.7.
I have a field of type list:string (using Sqlite). In 1.99.7, dal.py
breaks at line 1405 (marked with ):

the startswith('list:string') line is never reached.

[web2py] DAL or SQL?
I need to run a reasonably complex query, and I'm wondering whether it would be better to code it in SQL, or should I try to get the DAL to provide the data (or maybe there's another way). There's no right or wrong answer, but I'd welcome opinion on the best approach. Simply put, consider two tables, tasks and periods. As well as an id field, tasks has a 'name' field too. Each task has multiple periods (of work) associated with it, and the periods table has id, date, start_time, end_time (and other fields). What I want to do is produce a summary that lists: task_name total_time ...for each task. That is, for each period, find the duration by subtracting the start_time from the end_time, and total all durations for each task in turn. I can write this in SQL, but then I lose the advantages of the DAL, as well as potentially losing database portability. I'm not even sure if this is doable in the DAL. What would be the best approach? -- You can have everything in life you want if you help enough other people get what they want - Zig Ziglar. Who did you help today?

[web2py] Representing foreign field with image (format/represent)
I have a form based on a table which includes foreign fields. By default,
the foreign fields are displayed as the name from the foreign table
as expected.
I want to have an image displayed rather than the name from the foreign
table.
Not having used 'format' before, I changed the format of the foreign table
to:
format=xyz
As expected, every row now displayed xyz. I then changed to:
format=URL('static','images/red.jpg')
and again, as expected, the URL string appears in every row. Then I did:
format=IMG(_src=URL('static','images/red.jpg'))
and now no foreign key lookup seems to occur at all: I just get the id
value showing in the table.
I have two questions:
Why does that happen and
How can I display an image for a foreign key value?

[web2py] Application logging
What are others doing for application logging? I'm not referring to the
HTTP logs, but program-generated logs.
I've recently been looking at the Python 'logging' module, which I've not
used before. I initiate logging from a file in the 'modules' directory
which does this:
import logging
from logging.handlers import SysLogHandler
logger = logging.getLogger(MyApp)
logger.setLevel(logging.DEBUG)
hdlr = SysLogHandler(address='/dev/log')
formatter = logging.Formatter('tigerpy[%(process)d]: %(levelname)s:
%(filename)s at line %(lineno)d: %(message)s') hdlr.setFormatter(formatter)
logger.addHandler(hdlr)
Then each file that I want to log from does this:
import logging
logger = logging.getLogger(MyApp)
.
.
logger.info(Something interesting happened)
This logs to syslog: the only problem is that each logging message is
written to syslog many (20-40) times(!). This isn't just in one place in
my code, but throughout. I don't think the code is being executed multiple
times, so I'm not sure why I'm getting so many log entries.
So, I'm interested in what others do to log application events.

Thanks for the suggestion, but I don't have any other forms there. I'm using the authentication page that comes with Web2py, unmodified. I've checked the source of the page and there is only one form there. That authentication page has form action= so which URL is the form submitted to? I could then put the debugger on that function and check what is going on. Thanks -- To unsubscribe, reply using remove me as the subject.
Re: [web2py] Authentication: form just refreshes, won't validate login
Problem solved. For the sake of others searching on this: some of the distribution files under applications/my_app were from an earlier version of web2py. -- To unsubscribe, reply using remove me as the subject.
[web2py] Using Ajax to display detail from a list
What I want to do: have a list of items displayed; when one is clicked,
more detail is shown (via an Ajax call) in a defined detail area.
Problem: the web2py ajax call takes three parameters: a controller action,
one or more field ids, and a target DIV. My controller action needs to
identify which row has been clicked on, so I need a hidden field per row
that holds the row number. Because all field ids need to be unique, I
actually have to build a dynamic name for the row id (eg,
id=row_{{=row.number}}, name=row_{{=row.number}}), and - even worse - my
controller action doesn't know the name of the field passed, so it has to
parse response.vars to find it.
Web2py and Python in general are so well architected that I know there
must be a better way. Could someone point it out, please?
Thanks.

[web2py:19408] Re: The official Web2py Book by Massimo....for free?

This is not a complaint - I do not expect the book to be free - but the above point is valid. I too have the printed book, but a lot has changed since it was written. Some projects (the Claws Mail project springs to mind) include a list of new features with each release. Would that be something that web2py could do?

[web2py:18008] Deleted record returning
I'm returning to web2py after a bit of a break, so maybe things have changed in the intervening six months or so (well, I'm sure they have). Version 1.58 (2009-03-10 10:51:30) I have a SQLite database with a number of rows in it. I had been retrieving the rows with: todos_ds = db(db.todos.rt != 0).select(db.todos.ALL) I then edited one of the rows from the dba page. When I now run the above line, the returned dataset has the modified row in it and, right at the end, the original row with a new id. The dba page doesn't show the phantom row. I exited web2py altogether and examined the table with sqlite3: the row isn't there. I start up web2py, run the app to the above line, and the phantom row is in the dataset. I would struggle to believe what I've written above if I read it, but it is definitely true! Happy to make screenshots if you want. Can anyone explain what is going on?

The problem (for me, at least) is NOT the page itself, but the DNS entry for www.wellbehavedsystems.co.uk - I can fix the problem by flushing the local DNS cache here.

[web2py:10760] The Book
Received the web2py book yesterday (I'm in the UK and I had to buy it from Amazon in the US, and it took a while to ship). Good job, Massimo: I'm up to page 66 and it reads very well. Much better than the earlier versions posted on the website, although they were helpful too. I do have a couple of suggestions for the book: are you still interested in feedback (I'll send via PM when I've finished the book if you are).

Whilst I agree with the basic point you make about somehow saving the context of the editing if possible, if you don't trust web editors then why are you using one?? None of my web2py editing is done via the web interface for a number of reasons, not least of which is that there is no recovery journal.
