[web2py] Re: Issue with defaultdict(list)
After taking a break and working on another section, I finally found what
was causing the issue. There was, indeed, an error elsewhere within that
controller, which was causing me all the headache. I appreciate your guys'
help! Thanks.

[web2py] Re: Issue with defaultdict(list)
I think I've narrowed it down to having an error somewhere in my 'students' controller. 1. If I remove all other functions within that controller, it works. 2. If I create a new controller and only have that function, it works. 3. If I put the same exact code in another existing controller, it works. I will have do some more testing to figure out where my actual problem lies.Will report back with any results. -- 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.

I am running from source, but still seem to have the issue.

I was doing some testing and it seems to work perfectly fine when I run it
from default.py. However, any time I try to run it from the controller I
need it in, it doesn't work. I even created the "test" function that worked
for you, and I still get the "AttributeError: 'dict' object has no
attribute 'append'". This one has really got me scratching my head.

[web2py] Issue with defaultdict(list)
I seem to be having issues getting defaultdict to work within Web2Py. I am
using Web2Py version 2.16.1 (Python 2.7.11).
Here is the code in my controller:
from collections import defaultdict
g = defaultdict(list)
g['someKey'].append('someValue')
Here is the error I'm getting:
File "D:/web2py/applications/fpr/controllers/students.py"
, line
14, in view
g['someKey'].append('someValue')
AttributeError: 'dict' object has no attribute 'append'
If I do the same thing in the Python Interpreter, I don't seem to get the issue.
>>> from collections import defaultdict
>>> g = defaultdict(list)
>>> g['k'].append('v')
>>> print g['k']
['v']
Am I implementing this wrong or is there some sort of issue with using
defaultdict(list) in Web2Py?

[web2py] Re: Trouble Creating Update Form
I seem to have a problem there. It returns None.
However, I think I may have figured out a solution. I've managed to update
the current day 'rating' & 'complete' fields and also the 'complete' field
of the next day (making it current). Let me know if you see any problems
with the way I ended up doing this... Here is the code:
*Controller:*
def workouts():
r = db(db.workouts.complete == 1).select().first() #select
current day
form = SQLFORM(db.workouts, r, showid=False).process() #create
form to update 'rating'
if form.accepted:
r2 = db(db.workouts.complete == 2).select().first() #select
next day
r.update_record(complete=0) #update
current day
r2.update_record(complete=1) #update
next day
response.flash = 'record updated'
elif form.errors:
response.flash = 'form has errors'
rows = db(db.workouts).select()
return locals()
As far as I can tell it seems to work how I want it to. You've been more
than helpful, Massimo. Thanks, again!

It's still creating a new record rather than updating. So I've still got
something wrong. I need to look over the code and see if I can find
anything that sticks out.

[web2py] Re: Trouble Creating Update Form
The purpose of the app/page is to track progress of a workout routine. It
is a 5 week / 35 day schedule. I have all the "static" information stored
in the table (Day, Week, Workout Name), but there are 2 other fields in the
table that would need to be updated: "rating" which is where you rate your
performance (1-4) entered via radio buttons, and "completed" which can be
either 0, 1, or 2 (0=complete, 1=current, 2=locked) and is automatically
changed to 0 when the form is submitted.
I am generating the page by iterating through the records in the table and
displaying them (see here for example
<https://drewhowell.pythonanywhere.com/TwoFiveTracker/default/workouts.html>).
I realize now that I really only need 1 form, which is for the current day.
The user will select a radio button and click submit. It should then update
the "rating" field as well as the "completed" field. After the form is
submitted the page is generated again, but the next day will be the
"current" day with the form. I apologize if that's confusing, but the best
way to understand it is looking at the example
<https://drewhowell.pythonanywhere.com/TwoFiveTracker/default/workouts.html>
.
This is what I'm doing in my workouts.html View:
{{for row in rows:}}
{{if row.complete == 0:}}
// completed day layout
{{elif row.complete == 1:}}
// current day layout
{{=form}}
{{else:}}
///locked day layout
{{pass}}
{{pass}}

I made the changes and switched to using {{=form}}, but It's still creating

[web2py] Trouble Creating Update Form
I'm new to Web2Py, so I am creating a (what I thought was a) simple app
that tracks progress of a workout routine. I have a database (db.workouts)
that has information such as Workout Name, Rating, Completed, etc. I have 2
fields(rating, completed) I would like to update via a form. I have tried a
couple different methods, but can't seem to get anything to work correctly.
The other fields are already entered in the table and should not be changed.
"Rating" should be updated by a set of radio buttons and "Completed" should
be set to 0 when the form is submitted (0=complete, 1=current, 2=locked). I
have created the form, but have done something wrong because, when it is
submitted, a new record is created rather than updating the existing one.
*Here is my code:*
*Model:*
db.define_table('workouts',
Field('stage'),
Field('w', type="integer"),
Field('workout'),
Field('complete', type="integer"),
Field('d', type="integer"),
Field('rating', requires=IS_IN_SET([1, 2, 3, 4 ]),
widget=SQLFORM.widgets.radio.widget),
auth.signature
)
*Controller:*
def workouts():
rows = db(db.workouts).select()
r = db.workouts(request.args(0))
form = SQLFORM(db.workouts, r)
if form.process().accepted:
response.flash = 'form accepted'
elif form.errors:
response.flash = 'form has errors'
return locals()
*View:*
...
{{=form.custom.begin}}
{{=form.custom.widget.rating}}
{{=form.custom.submit}}
{{=form.custom.end}}
...
As I mentioned earlier, I am new and I may be going about this completely
the wrong way. So any help would be greatly appreciated. I can provide more
information if needed. Thanks.
