[web2py] Re: DB Insert Variable Names
I've fixed the issue with the variable names by prefixing a letter to the variable. However, the insert still does not function. Here's the error: 127.0.0.1.2013-03-04.11-38-23.96eaf75d-0524-4eb8-8848-6000d1993dcd class 'gluon.contrib.pymysql.err.InternalError' (1048, uColumn 'Q4_3A' cannot be null) Traceback (most recent call last): File gluon/restricted.py, line 212, in restricted File C:/Users/abond2/Desktop/web2py/web2py/web2py/applications/Teacher_Evaluation_System/controllers/evaluation.py http://127.0.0.1:8000/admin/default/edit/Teacher_Evaluation_System/controllers/evaluation.py, line 84, in module File gluon/globals.py, line 193, in lambda File gluon/tools.py, line 2929, in f File C:/Users/abond2/Desktop/web2py/web2py/web2py/applications/Teacher_Evaluation_System/controllers/evaluation.py http://127.0.0.1:8000/admin/default/edit/Teacher_Evaluation_System/controllers/evaluation.py, line 28, in Take_Eval File gluon/dal.py, line 7918, in insert File gluon/dal.py, line 1176, in insert InternalError: (1048, uColumn 'Q4_3A' cannot be null) line 28, in Take_Eval refers to the insert method.

[web2py] Re: Creating a form using a for loop
I figured this out later on - I've adjusted all the variables and field
names to start with a Q. Thanks.

I think your compilation error comes from the fact that in Python you
cannot have a variable name starting with a number. Try changing the field
names of Evaluation table to letter_1_1A...
Then remember that only one form can be submitted in HTML, so your
controler will be called only for one submitted form, not all.

I've been working with web2py for about two months now. I've figured
out how to do a lot of awesome things with it; however, the problem I'm
having now has me stumped.
I'm working on an application that allows a user to submit a
self-evaluation, based on criteria that the user will find on a page. I
have a table with 33 rows of of criteria. The table contains a column
which hosts the criteria, pre-formatted in HTML. Each HTML section
contains a table the gives the users the criteria for each of six levels -
these individual tables are almost large enough to take up the entire
content section of the webpage, so I've placed them all in a jQuery
accordion. Below each table, I've placed a drop down list, where the user
can select what criteria they feel as though they've met. I've added a
small screenshot to show the look and feel I'm trying to achieve (and
currently have).
The problem I'm having is getting the values of those drop down lists
back from the database. Currently, I iterate through the table containing
the HTML using a for loop, tacking a drop down list at the end of each.
Right now, I'm unable to get the data back from the page. Here is my
code:
def Take_Eval():
user = db(db.Person.auth_userUserId ==
auth.user.id).select().first().PersonId
table = db(db.PageContent.ContentId 0).select()
submit = INPUT(_name='submit', _type='submit')
formlist = []
for row in table:
newForm = FORM(H2(row['ContentDescription'],
_style=padding-left: 10px;),
DIV(XML(row.ContentHTML), BR(), P(SELECT(OPTGROUP(OPTION('Does
not Attempt', _value=0), OPTION('Developing', _value=1),
OPTION('Progressing', _value=2), OPTION('Established', _value=3),
OPTION('Advanced', _value=4), OPTION('Master', _value=5)),
_id=row['QuestionNumber']), _style='text-align: center;')))
formlist.append(newForm)

The values shouldn't be null - it should be a int value from between 0 and 5. Even if the user didn't select any items, the default value will still be 0 from the drop down list.

[web2py] Creating a form using a for loop
I've been working with web2py for about two months now. I've figured out
how to do a lot of awesome things with it; however, the problem I'm having
