so how do you present only a subset of values for the select element of a

it
should be in the referencing table, however, it is ok to leave it blank and
the controller will handle it according to design. how do i define that

return "omg dude"
also tried:
def ajaxLectureItems():
return OPTION("omg dude", _value="1")
and other permutations, but i am just not getting any return result with no
errors. so i think it is in the onchange area somewhere. using web2py
1.99.2. lucas

however, how does web2py execute string into code, run it, and return the
"return" variable that has the dictionary keys:values generated from that
executed code?
lucas
--
what using restricted or snapshot? would that be best and is it visible to
us normal web2py users?
--
ok, that is fine for simple code execution, but what of the more complex?
how does web2py execute all of that complex code we can embed within a
view? that is what i want to reproduce in my scheme.
--
field,
allow web2py to execute it, and finally return the dictionary so that it
can be further used in the view or other processes. i know it is a bit
dynamic, and thus difficult to give more details, so i am hoping that that
is more clear. let me know. ok. lucas

ok, i see the source code for restricted but its use eludes me a bit. how
do i grab its executed processed output?

i have been having a problem with users logging in or registering. web2py
seems to crash on some level and returns an internal error after the user
hits submit upon registering or logging in. i was initially getting the
error on my web2py version installed of 1.99.2, so i updated to the latest
in
those areas i will capture exceptions and rollback as suggested. what
exactly is the exception for the db or DAL? like

try:
some code
except DBException on e:
db.rollback()
return 'db exception: %s' % e
just so that i can at least return more tracking information also. lucas

so i am still having trouble finding if it is the postgresql-9.1, the pg8000

yes, i can reinstall the psycopg2 rpm package. how do you specify and
ensure that web2py is using that driver in the DAL?
sycopg.so:
undefined symbol: GSS_C_NT_HOSTBASED_SERVICE
is there a good forum for psycopg2 anywhere? lucas
--
it took a while to figure this out, but with the postgres repository that i
am using for 9.1, the python-psycopg2 rpm that is installed on my system is
from the pgdg91 repository. so i would have to conclude that the psycopg2
driver from that repository is for postgresql-9.1 and not the centos
nions. lucas
thanx in advance and i look forward to your experienced opinions. lucas
wow, really, so did you actually install freebsd on your EC2 harddisk slice
because i don't see freebsd under the amazon EC2 operating systems. i do
see redhat enterprise 6, which is probably very very similar to centos 6.
and with that freebsd install, did you install and use a relational

e not in database". i believe it is not referencing
the id from the pull-down list properly, or so.
please suggest. thank you in advance. lucas

so isn't there a better way then the try|except block. lucas
dy.append(d)
and i have noticed with say two DIV opinion forms that web2py is giving
different values for the _formkey. good. so why is it when a user enters
in their opinion and pushes submit, it does not enter the opinion in the
database? is there a better way to structure this so that the function
accepts the processed form? what is the best method of creating forms via
a loop or on the fly based on database records?
thanx in advance, lucas
? or,
what is the best approach to soft-coding variable names in python to
achieve that? thanx in advance, lucas
sure i can us the id from the table of sections. but how to i attach that
id number to a variable and python recognize that "string" as a variable
name that i can then access again for the form processing? i guess this is
more of a python question now then a web2py. lucas
i did try messing around with
f = SQLFORM(db.opinions)
f.vars.stuff.assignments...
exec 'f%s = %s' % (i.id, f)
if (exec 'f%s' % i.id).process().accepted:
session.flash = 'Thank you for your opinion'
omg, that is so totally working. cool.
i am almost there. i added this at the top of my function
if ((request.vars._formname<>None) and
(request.vars._formname.rfind('opinion_')>-1)):
f = SQLFORM(db.lecture_item_opinions)
f.vars.lecture_id=lecture.id
f.vars.lecture_
yes, thank you so much. i learned some very subtle things here and i love
the way it works. thank you so much. web2py is so powerful and so cool.

even simpler like,

i think this is easy. how do you get the actual record/row total/
count for a particular table in web2py under DAL? thank you in
advance and have a great weekend.
lucas
thank you to both of you. i am learning this stuff and i always have
to start at the base. lucas
ional_title.requires =
IS_IN_SET(('','Ph.D.','M.D.','Ed.D.','M.B.A.','C.P.A.','P.A.','M.S.','M.A.'))
auth.define_tables()
but the bottom two requires to fill the lists are bugging out.
suggestions on this modify? i don't need a custom auth_user so that
is why i am trying to modify the default one.
also, i would like to change to field order. how can i do that also?
thank you in advance and have a great day. lucas
that view?

makes the form look a little funky if you set this classes in the css
file. that could be fixed in the future correct?

l that
means is that user f...@gmail.com should be a Guest with permission
set to true for "News Restricted". ok?
how come when f...@gmail.com is logged in, auth.has_permission('News
Restricted') proves False. Shouldn't it be True?
thanx in advance and have a good day. lucas
y filter out the restricted rows,
compile and display only the unrestricted rows? interesting
suggestion.
but i still can't get a True out of has_permission. that one first.
thanx again. lucas
btw, i am using 1.98.2 and will probably upgrade to 1.99.2 soon.

i guess that does give the most optimum customization and control.
