[mdipierro]

Do you have an ajax generated by code inside another ajax request?
I believe SCRIPT(...) is returned but never executed for the same
reason as in your code at the beginning of the thread: ... inside ajax content are ignored by the browser.

I have it working now and it seems that the main thing I have changed to
make it work was to change the name of the field (from 'id' to something
else).  I did not check afterwards in the documentation but I suspect that
SQLFORM.factory uses an 'id' field (hidden).

What I could not understand was that when I the normal crud form in the html
there were two identical fields('id') although I had only one in my
definition.  Changing the name of the field corrected that and the
redirection took place as expected.

I for one am happy with the current release cycle. It is a good balance 
between new features and the ultimate stability of release 1.XX.N  where N 
is the last version before XX+1 for example. The nightly build is a bit of a 
misnomer, many projects (C or C++ mostly) have some automated process that 
takes trunk and compiles it to produce a .tar.gz labelled nightly which 
"might" work. For web2py we should just hg pull; hg update to achieve that 
result. The nightly for web2py is more like a beta because Massimo hand 
picks code from trunk that will or will not be in the nightly which could 
really be a weekly.

I am currently developing the application I am working on and testing is 
easy enough that I test trunk at least daily. The web2py server is quite 
easy to use but the code in some places is complicated and has many possible 
use cases. It is only through exposure out to the user base that a large 
number of use cases of the code get tested. I have even seen problems 
reported where something was fixed but used by maybe one person in a way 
that should not have worked resulting in the dreaded bug that worked and 
became a useful feature for someone.

Once I go to production I will probably move the releases a lot slower 
through the installed base. In fact I have 2 beta production systems up now 
and only push a new web2py when I push a new version of the application to 
the stakeholders to look at.

Massimo provides a fantastic service with the web2py project and I would not 
like to see him stifled by a load of process. Anyone that has time to test 
will definitely help the quality, if you don't have time, that is okay too. 
I personally don't mind doing some release management between where Massimo

[web2py] Re: ajax polling with web2py

[weheh]

Problem with my example above is that the setInterval is not being
executed after the callback.

[web2py] Re: ajax polling with web2py

[weheh]

OK, I think I see what you're doing, but when I apply it to my
ultimate app as opposed to the test case, it doesn't work. Here's an
example that's practically identical to what I'm trying to do (some
names have been changed):

#view
def poll(job_id):
 
filename=db(db.mytable.job==job_id).select(db.mytable.filename).first()
  if filename:
return show_job_results(job_id,filename)
  else:
return show_wait_icon(job_id)

def show_job_results(job_id,filename):
  ... # this displays OK ... no need to discuss here

def show_wait_icon(job_id):
  return DIV(
IMG(_src=URL(...path to wait icon .gif...),_alt='waiting'),
SCRIPT("""
  function update_job_status() {
ajax('refresh/%(id)d',['job-%(id)d'],':eval');
return false;
  }
  setInterval('update_job_status()',5000);
  """%dict(id=job_id)
),
_id='job-%(id)d'%job_id
  )

# controller
def refresh():
  if not len(request.args): return 'false'
  try: id=int(request.args(0))
  except: return 'false'
  return """
jQuery("#job-%(id)d").html("%(poll)s");
setInterval("update_job_status()",5000);
"""%dict(id=id,poll=poll(id))

The idea being, that as long as the job output file is missing, then
keep polling every 5 sec.

[web2py] Re: ajax polling with web2py

[mdipierro]

yes and no. First you missed a return false. Without that the page may
get reloaded.

#view
DIV(A('click me',_href='#',_id='parent',_onclick("ajax('clickback',
['parent'],':eval');return false")))

#controller
def clickback():
  return 'jQuery("#parent").html("%s");' %\
 SCRIPT("alert('hello world');")


now the jQuery returned by clickback will be executed on ajax but the
second the SCRIPT inside the html will never be executed. But you can
do:

#view
DIV(A('click me',_href='#',_id='parent',_onclick("ajax('clickback',
['parent'],':eval');return false")))

#controller
def clickback():
  return 'jQuery("#parent").html("whatever");alert("hello world");'

and now the alert will be executed.

Did this answer your problem?

the JS returned by the clickback

Massimo, I appreciate the response, but am finding your answer very

[web2py] Re: ajax polling with web2py

[mdipierro]

It depends on how you do the ajax call:

I suggest you can use the web2py_ajax.html function:

   web2py_ajax_page(method,action,data,target)

For example in view

click
me


and in controller

def callback():
response.js = "jQuery('.flash').html('hello!').fadeIn();"
return "hello world"

[web2py] Re: ajax polling with web2py

[weheh]

Hi Kuba - I believe it is the same or similar issue. I posted a
similar issue a few months ago and never got a response. Anyway, this
is mission critical for my app. I have a background queue that's
generating data for display. While it's running, I have a javascript
that should be polling the queue to see if the job is done. If done,
it should display the job results. Otherwise, it should show a wait
icon. Problem is, the queue is launched via an ajax. After launching
the queue, the controller then writes an ajax script to a target div
for the purpose of polling the queue. However, this newly generated
ajax never gets executed, so the polling doesn't work. I know of no
other way to do this other than to refresh the entire page, which is a
kludge. I know refreshing the whole page would work because the
polling routine runs if it is loaded at the time the page is loaded.

I'm stuck and need some help here. Has anyone ever gotten something
like this to work?

I took a second look. The first problem is indeed fixed. The second

[web2py] Re: The stability of web2py releases

[mdipierro]

I think the issue can be solved by labeling releases and posting older
- more stable - releases.

This is what I do now:
- I always work on trunk - trunk is very unstable
- Once in a while when trunk is stable I post a "nightly build" which
is more like a release candidate. It does not change nightly, but more
likely weekly as more and more features are added.
- When I have no open issues AND I am happy about the nightly built, I
post it as stable.
- The first stable is usually 1.xx.1 - this is when problems usually
starts...
  1) one problem is occasionally build errors that may affect GAE,
Windows or Mac
  2) one problem may be bug in new features that were not very well

[web2py] Re: ajax polling with web2py

Let me try to state this more succinctly:

How do I get a jQuery, which is created by a controller in response to
an ajax call, to execute when loaded into it's target div?

Sorry, I'm sure I wasn't clear. The routine I posted does not work.
The parent div is properly updated, however the alert is not executed.
I want the alert to be executed without further action by the user.

Massimo, good news. Web2py is successfully being adopted by more and
more developers who are using it for very serious purposes. It's going
viral. Therefore, there need to be at most a few major releases a year
and a bunch of incrementals in-between.

I anticipated a challenging release with the latest DAL changes. At
enterprises where I've worked in the past, changes to the db layer
were always considered major releases. That's when the troops were
mustered to test en-mass before pushing the product out the door.

Web2py quality must always be of paramount importance. In the absence
of a delegate, we look to you to lead this issue. It almost goes
without saying that doing it right will ultimately have a larger
impact on web2py's credibility than upgrading the documentation did.
But, doing it wrong will have immediate disastrous consequences.

Re: [web2py] ajax polling with web2py

[Michele Comitini]

I do not know what criteria you would use to understand if #parent is
acceptable or not but you
can pass as many other ids as you need:

DIV(A('click me',_href='#',_id='parent',_onclick("ajax('clickback',
 ['parent', '2nd', '3rd', ... 'nth'],':eval');")))


#controller
def clickback():
 for t in args:
   if kosher(t):
 target = t
 return 'jQuery("#" + target).html("%s");' %\
    SCRIPT("alert('hello world');")

Maybe we should keep a comparison just on web2py.com.  Pay attention
to framework lists around and putting a sane description there.
It is useless and even counterproductive starting flame wars in
threaded discussions.  It is more importante that googlers find web2py
when
they search a good framework to work with.

[web2py] ajax polling with web2py

[weheh]

How would I do this?
#view
DIV(A('click me',_href='#',_id='parent',_onclick("ajax('clickback',
['parent'],':eval');")))

#controller
def clickback():
  return 'jQuery("#parent").html("%s");' %\
 SCRIPT("alert('hello world');")

So that when I click on "click me" it calls the clickback, which
inserts the alert on top of the same parent. If overwriting one's
calling div isn't kosher, then I'm OK targeting a second div.

Flask is nice and I am not complaining about it. Yet, if I needed
something small where web2py was too much overhead (and it can be I
guess), I would go with bottle.py+dal.py. The bottle source code is
beautiful and the routing mechanism seems similar to flask.

[web2py] executing code from db

[mattynoce]

hi all. i know this doesn't sound like a superb idea, but i may have
to do something like it.

i have data coming from the db and being displayed to the user as
instructions. "do this," "go there," etc.

i'd like to have that data executed in the environment, so i could say
"do this, {{=user.first_name}}." but when i say
{{=XML(instruction.step)}} it spits out the raw text but doesn't
execute it.

this only happens for db info that we put in, no user data. is there a
way to run it through the web2py interpreter before displaying it to
the user?

thanks, and happy holidays.

True.



I've recently tested Flask briefly. I didn't like it's way of routing.
But then I realized something (and Flask docs confirm that as well).
Flask and web2py are not even in the same league. Flask was developed
to handle small stuff, where having routing stuff dispersed around the
code base is acceptable, because the codebase itself tends to be small
in such projects. But that sucks for larger projects. In contrast,
web2py is geared towards far more organized code, and therefore larger
projects. At least to some extent. I'm not sure about globals, but I
don't develop large projects myself, so it's fine for me.

So I don't even understand how Flask can be compared to web2py at all.
Two different things, with two different design goals.

Good. Now this thread can go into the list of many archived threads about
this topic.

Nothing will happen and things will continue as they have been, which isn't
so bad because nobody is forcing you to upgrade your web2py version each
time a new release comes out.

However, Branko, part of the problem that nobody else can even perform basic
release management. Nobody but Massimo has access to trunk, and therefore
nobody but Massimo can make releases, create branches, maintain stable etc.
This leaves the project in a odd state that the only thing that can be done
is to complain.

Its free software, if you don't like it, fork it and manage it yourself.

My comment is not just about that specific thread of discussion, but
about a general PR strategy of web2py.   My suggestion to Massimo
still stands.   Forget about Flask and Django !!!  Don't talk about
them at all.  None. Nothing.

People who think that Django/Flask are superior to web2py, and/or
web2py is deeply flawed, aren't changing their minds.  There's no
point to debate, justify, etc.

I do not see much benefit for web2py when Massimo discusses Django/
Flask.   On the other hand, the (serious) newbies will get lost in hot
exchanges between the web2py folks and the Django/Flask folks.
Occasionally, this dude Armin will come around the proclaim web2py to

You're welcome. It also helps if you build a virtual environment for
developing your apps. Keeps things clean.

First you get virtualenv package with:

$ easy_install-2.7 virtualenv

Then you just run this:

$ virtualenv --no-site-packages /path/to/my/env
$ cd /path/to/my/env
$ source bin/activate
(env) $ python

You'll notice that the interpreter version is now 2.7.x within the
env, and that '(env)' is printed before your prompt. As far as I know,
you cannot exit the environment other than by exiting the shell
altogether.

The environment is sealed off from your local Python install, so
anything that you install within your environment is available only
within the environment and if you use the ``--no-site-packages`` flag,
no packages installed in your local Python path will not be accessible
within the environment. Now, to develop with web2py within the
virtualenv, you just copy web2py dir into the virtualenv dir, and
that's it. Now you can run ``./web2py.py`` normally and web2py will
use the interpreter installed in the env.

Yes, yes. Sit around and wait. For what reports again? Based on what
bug reports again? Everyone was sitting and waiting for Massimo to
actually label it as stable release. How wonderful. I'm sure that's
the BEST strategy to ensure web2py is bug free in future releases. Oh,
and what happens if Massimo's stable release turns out to be not that
stable after all? Well, this thread happens.

Last I've heard, Massimo was a single person. I don't know if he can
multiply like amoebae, but I'm sure it'd help if we all just dug into
release candidates or even trunk and _at least_ poked around. Even
better, why not deploy your latest awesome project on the new release
and give it a spin?

All in all, some of you guys are just... I dunno. Irrational. (Or
retarded, but I hope not.) You take far too many things for granted.
FAR too many things. And you fight any notion that doesn't match that
vision. So you don't see the beauty of free software, fine. But what's
this?! Even free as in beer isn't enough for you! You want it ALL. And
what IS the 'all'? Even you don't know. I'll tell you what you want.
You want open-source projects to submit to YOUR selfish and
self-centered vision. Instead of talking about contribution (of your
valuable time to the project that SAVES your valuable time), you
demand, and demand, and demand.

You keep babbling about your selfish needs, not even considering that
there are actual people who have THEIR OWN needs and yet make time to
listen to you, and implement shit in record time. And again, it has to
be said, that saves you your valuable time. Is that not enough for
you? Doesn't that make you happy? Is that ENOUGH?

Well, you know what. You should all be ashamed. You have absolutely NO
RIGHT to demand anything from Massimo or any other contributor. And
don't tell me about how you love web2py but you just wanted X or Y.
You OWE web2py X and Y, so if you want it, just do it yourself. YOU
label releases as stable, and YOU implement stuff. If Massimo does
that for you, it's a BIG FAT favor, and you should keep that in mind.

I think it's definitely a worthwhile goal to evolve the release schedule 
into stable and feature branches with bugs getting back-ported but suspect 
it will take some time to get there.

Part of the value of a framework is being able to count on its stability. 
For now, we can upgrade more slowly and pay attention to stability reports 
of new releases.

Arch is defaulting to Py3k. Just run into this minutes ago. :D

Try this:

I have a theory. Or at least a conjecture.

Try looking request.env.query_string. My guess is that, in the case where 
you're seeing a list, indx is showing up twice in the query string from your 
form. When that happens, web2py puts the values into a list. That's recent (but 
correct) behavior on web2py's part, though it's not handling the URL() case 
correctly yet.

Because I'm not deploying it (the current version, that is). 

For the same reason we don't tell users that they *must* use Python 2.7.1, and 
re-test their 2.4-based code for compatibility: it works.

Not me personally; I use the latest versions of stuff, pretty much. But I 
understand the reason for not wanting to, or at least not wanting to have to.

Nope,

Problem is still there.
If table is empty, it renders form.
But, as soon as there's items in table, it'll cease to render anymore.

BTW., I'm not using this table as a single form, so it's not effecting me 
now. But I want it resolved. Who knows, someday I've to use this.

Re: [web2py] Url variable's problem

[Arun K.Rajeevan]

It's not a list.
Complete logic is given in the first post, where this index is forming.
Hidden field's value is set when select box changes.
and is retrieved in form.accepts() 
that's all.

Each time, I select an item hidden field's value changes. (I tried with 
firebug console.)
And why this is happening? 
I'm not getting any clue.

Massimo:

Perhaps you can explain why indx is becoming a nested list, but setting that 
aside, if it *is* a list, I think the query string should be something like:

?indx=19&index=10&indx=5

That would require some additional logic in URL() for vars.

[web2py] Url variable's problem

[Arun K.Rajeevan]

See following code, 
I expect it to redirect to a url 
1) if user don't touch dropdown: 
http://127.0.0.1:8000/init/default/search//?indx=0
   but it shows http://127.0.0.1:8000/init/default/search//. *Why 
no vars?*
2) if user altered dropdown: 
http://127.0.0.1:8000/init/default/search//*?indx=5*
 it's ok for first time. But if user select another item from select box 
*?indx=['10'%2C+'5'] 
*
 and if select another one *?indx=['19'%2C+"['10'%2C+'5']"]

Where did I went wrong?
*

In controller, before all functions, I've following,

options = [OPTION(row.full + '  - ' + row.short, _value=row.id) 
for row in db().select(db.languages.ALL, 
cache=(cache.ram,3600)).sort(lambda a: a.full)]
options.insert(0, OPTION('All Langauges', _value=0))
search_form = FORM(LABEL('Search a word: ', _for='word', _id='word_label', 
_name='word_label'),
INPUT(_id='word', _name='word', 
requires=IS_NOT_EMPTY()), 
SELECT(_onblur="var f = document.search_form; 
f.indx.value = this.selectedIndex;", 
_name='languages', _id='languages', 
requires=IS_IN_DB(db,'languages.id'), *options),
INPUT(_type='hidden', _name='indx', _id='indx', 
value='0'),
INPUT(_type="submit",_value="SEARCH"),
 _name='search_form')

# form verficaion logic on submission
if search_form.accepts(request.vars, formname='search_form', 
hideerror=True):
lang = search_form.vars.languages
word = search_form.vars.word
indx = dict(indx = search_form.vars.indx)
redirect(URL(r=request, f='search', args=[lang, word], vars=indx))
elif search_form.errors: #adding an element in option out of the db braked 
prev mechanism. (ie., showing a flash. now that's done by show() itself.
lang = search_form.vars.languages
word = search_form.vars.word

else:
#page loads first time

[web2py] Re: Encountering problem with a computer field

[Magnitus]

I've thought about the dependencies problem a little bit.

Maybe add some kind of hook so that the user can define the
dependencies of the computed field himself.

If he doesn't define them, the current behavior occurs.

If he defines them, the behavior could be as follow:

1) All the dependencies are present in the input

The field is updated from the input

2) Part of the dependencies are present in the input

The current behavior occurs. Alternatively, try to read the missing
dependencies from the DB (for an update) or from the default values
(for an insert), but I'm not sure how complicated that would be.

3) None of the dependencies are present in the input

The computed field is not updated.

>From the above, you'd get the best of all worlds.

1) User friendliness: The user doesn't have to define dependencies if
he doesn't want to and he'd get the current behavior.

2) Flexibility: The user can define dependencies in which case the
computed field doesn't restrict updates that don't include the
dependencies on the field.

3) Correctness: Exceptions due to mistyping variables are not caught
and properly raised.

Yes; that's an error, per RFC 3986.

  URI = scheme ":" hier-part [ "?" query ] [ "#" fragment ]


Not only that, but '?' is legal in a fragment identifier, as is '=', so in your 
first example, "end?v=yes" is itself the entire (legal) anchor.

I wouldn't be terribly surprised if some browsers treated this inconsistently, 
but we should be adhering to the RFC here.

The fix looks easy; change:

if anchor:
other += '#' + urllib.quote(str(anchor))
if vars:
other += '?%s' % m_vars

to:

if vars:
other += '?%s' % m_vars
if anchor:
other += '#' + urllib.quote(str(anchor))

...and fix the doctest. Though I'm not sure that urllib.quote is right for an 
anchor.

Seriously: no.

That is, if I'm using a release from six months ago, and all I need is a point 
fix, there's no reason for me to spend any time testing new release candidates. 
The bulk of web2py users, presumably, are not focused on web2py development; 
they're simply using web2py as a (very effective) tool to get their real work 
done. And there's nothing wrong with that.

[web2py] Possible bug in URL

[mr.freeze]

Given this url:
URL(args=1,vars=dict(v='yes'),anchor='end')
It produces:
http://server/app/default/index/1#end?v=yes
Problem:
request.vars is empty

This url:
http://server/app/default/index/1?v=yes#end
request.vars is populated and the anchor works

Shouldn't the anchor be at the end of the query string? I'm running
the latest trunk.

That's another reason why you want to help test the 'release

[web2py] web2py_utils bug

[Francisco Feijoo]

Hello everybody,

this is my first post in the group. THANKS for this great web
framework.

I want to include tests in my project. Searching I found web2py_utils
(web2py_utils-0.0.13dev) and test_runner as the best tool for web2py
and unit test.

Running the tests I have this error:

File "/usr/lib/python2.4/site-packages/web2py_utils-0.0.13dev-
py2.4.egg/web2py_utils/test_runner.py", line 193
test_db.define_table(tablename, *table_copy, migrate=True)
   ^
SyntaxError: invalid syntax


I have replaced the line with:
 test_db.define_table(tablename, migrate=True, *table_copy)


Is web2py_utils a good tool for testing web2py applications? Is
someone resposible for utils project to update the code?

Cheers

The problem is that if you *do* need a bugfix, you ordinarily can't get it 
without adopting all the changes since the version you're currently using 
(unless you do your own patching).

Also, if the submit results in a database insert, and the insert fails. I think.

And if there's a formname mismatch.

It seems to me that if accepts() fails, there always ought to be a reason 
reported. Would it break compatibility to report these errors in form.errors? 
If so, how about creating form.formerrors and guaranteeing that if accepts 
returns False, formerrors will say why.

...but that's not really true. There are several reasons for failure that are 
not reported in form.errors.

(One of them is that the form has not been submitted yet. I find that logic 
really confusing: what's the path, exactly?)

Re: [web2py] Re: translation dict name

[Richard Vézina]

Find it!

My only remaning problem is the # coding: utf8 at the top of translation
file... I don't see how dal.py manage it... I could made a readline and
remove it in a other instance of the open file or something like that, but
should have a simpler way to manage it.

Re: [web2py] Re: translation dict name

[ron_m]

web2py uses portalocker.py look under gluon. There are many examples of use 
such as locking the session file in globals.py

Re: [web2py] Re: translation dict name

[Richard Vézina]

Ok, I think I found what you do :

>From the DAL.py

Version 1.88.2

tfile = open(self._dbt, 'w')
portalocker.lock(tfile, portalocker.LOCK_EX)
cPickle.dump(sql_fields, tfile)
portalocker.unlock(tfile)
tfile.close()
if self._dbt:
if fake_migrate:
logfile.write('faked!\n')
else:
logfile.write('success!\n')
else:
tfile = open(self._dbt, 'r')
portalocker.lock(tfile, portalocker.LOCK_SH)
sql_fields_old = cPickle.load(tfile)
portalocker.unlock(tfile)
tfile.close()

[web2py] Re: couchdb support again

[ron_m]

ii  python-couchdb  
0.6-1   
from Ubuntu 10.04.1 dpkg -l
I have to go visit a customer site today so will look again tonight. I think 
it is probably time for me to update direct from Apache. This may be a 
problem since the rest of the release actually uses CouchDb. I am very 
interested in getting this going so will do what I can - this I am thinking 
would be a good database for me to store configuration data in since it has 
a multi-master disconnect model that still resolves replication issues. I 
would have to go into it a lot deeper to explain why but will skip it for 
now.

[web2py] Re: Cache stored at request, does not sync with other threads until new request

[Dragonfyre13]

So I've gone back and forth on this again and again. It looks like
cache.ram being process bound (so even though I only have one web2py
instance, it's running across multiple wsgi processes?) was the
problem. The issue is, I'm having similar issues (in a very different
location) using cache.disk. I though maybe it might be better to use
memcache instead, but I get a keyerror when trying to use memcache to
cache the DAL, since my key regularly exceeds 250 chars (relatively
small query, but lists every field it looks like)

Re: [web2py] Re: translation dict name

[Richard Vézina]

Hello Massimo,

I have one more question about the process of pickle the translation
file...
Do you lock file with "flock"? Or just open the file and close it after the
pickling and applying transformation to the dict is enough to lock the file
during the process?

Is this code correct to not having concurent access problem?? :

f = open("file.dat","wb")
pickle.dump(x,f)
f.close()

f = open("file.dat","rb")
y = pickle.load(f)
f.close()


Thank you

Richard

Re: [web2py] customizing size of form fields created using field.custom.widget

[Martín Mulone]

Add to your css definition or in /static/CSS/base.css this rule and
tell if this is working:

#task_estimated_time_unit {width: 80px;}

Re: [web2py] Re: Merry Christmas

[Bruno Rocha]

I wish a happy new year to all of the group. and that 2011 will be a year of
achievements and more good developments for our dear web framework.

This year I were actively connected with the web2py development. I put aside
other technologies (kicked the ass of my bosses) and founded my own
small-company and we had a great year working with 100% of the projects
developed with free software and Python (almost all in web2py)

I thank Massimo and all group for everything that I learned here in 2010.

We hope 2011 to be a great year to everyone. (Let's kick asses creating
great open source systems with web2py in 2011)

(we are going to take a break, no internets or code until next year)

Happy new year to you all!.

[web2py] Re: form.accepts = False. How to find out why

[DenesL]

Two things to check:
1) you might have session.forget() in the controller, maybe outside
the action.
2) you might be using a custom form and it is missing the hidden
fields,
   if you don't have the _formkey then the form will not be accepted.

[web2py] Re: App admin error

[mdipierro]

At some point in time you changed

Field('word', 'reference words', ...)

to

Field('word', 'list:reference words', ...)

and you had data in the database. SQLite let you do that (because
SQLite does not check field type and does not support alter table), so
now you have corrupted data in the table and you cannot select it any
more.

You need do delete your database

   rm applications/app/databases/*

and start clean.

[web2py] New to web2py

[Monte Milanuk]

Hello all,

New guy here... I've been looking all over the web for something that
meets all the needs of a couple projects I want to do, and it looks like
web2py will just about cover them!

I'm getting my feet wet with the examples, and got sidetracked ;) by the
gae sql designer - holy cow that thing is sweet, not too complicated,
just right!  I was noticing that it seems to use the old DAL language of
'SQLField' instead of 'Field' for the table definitions... is there an
update or change in the works for that?

Also... maybe my understanding of foreign keys as used in web2py (or at 
least the gae sql designer) is not up to snuff... it seems like this:


dbOBJECT.tbl_phone_numbers.id_tbl_members.requires=IS_IN_DB(dbOBJECT,
'tbl_members.id','tbl_members.title','tbl_members.first_name',
'tbl_members.mid_init','tbl_members.last_name','tbl_members.suffix',
'tbl_members.street1','tbl_members.street2','tbl_members.city','tbl_members.state',
'tbl_members.post_code','tbl_members.country','tbl_members.gender','tbl_members.nra_id')

should be just:

dbOBJECT.tbl_phone_numbers.id_tbl_members.requires=IS_IN_DB(dbOBJECT,'tbl_members.id')

since I'm just wanting to tie those two fields together, not the one 
field to the whole other table... yes/no/maybe?


TIA,

Monte
