[web2py] Re: Getting wrong Results with my grading system
What i want is to reflect an a 'A' if a student gets anything between 100% and 80%, hence the line if perc>=100: grade='A' and get grade 'B' if a student gets anything between79% and 70% hence the line elif perc>=79: grade='B' elif perc>=69: grade='C' When i coded it i thought it's straight forward it'd reflect correctly but instead 70% gives me 'C' and 80% to 90% give me a 'B' I Cant figure out what I'm doing wrong where!

[web2py] Re: list:string field length
Issue may be with SQLFORM rather than Pydal - if I have a list string field in my case its called answers and put it in a SQLFORM then in form.validate if you do print type(form.vars.answers) I get str when there is 1 item in my list and list when multiple answers and so my validation includes a line like this: if isinstance(form.vars.answers, list) and len(form.vars.answers) > 1 and len(form.vars.answers[1]) > 0: I just thought I'd mention it as something to be aware of if you start using length with list string fields as I always expected it to be a list.

[web2py] Re: threading Lock
Do you want to lock between processes or just threads? If it's just between threads you can just put the lock in a module instead of a model file. Models are executed again on every request so you're creating a new Lock each time so threads will be locking different lock instances. Between processes you can use Dave's suggestion or you can use portalocker which web2py includes. -- 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.

If you are starting the scheduler worker as above, the scheduler and scheduler task must be defined in the context of a web2py app, not a standalone script. From your script code, the function defining the task should either go in a model file in the app or go in a module and be imported into a model file. The code defining the scheduler should go in a model file in the app. And the code queuing the task should be executed elsewhere -- you can run the queuing code from a web2py shell, define a controller action that queues the task, or even directly add a record to the scheduler_task table (possibly via appadmin) to queue a task.

Browsers retain and keep sending back the session cookie (throughout the course of a browser session), so web2py can continue to identify the browser with a particular session. Be default, curl does not retain cookies and send them back to the remote server on subsequent requests, so web2py has no way of associating each curl request with the same session. JWT auth does not work via cookies. Rather, the JWT goes in the HTTP request headers. So, with curl, you are sending the JWT to web2py on every request, and web2py is able to validate the JWT on each request (the JWT can be validated based only on its own data -- nothing from a server-side session is needed to validate it). web2py, therefore, is not "keeping you logged in" -- you are really re-authenticating on every single request by sending the JWT in the request headers. By the way, you can use curl to store and return cookies using the --cookie and --cookie-jar options.

The use of {{pass}} is explained
here: http://web2py.com/books/default/chapter/29/05/the-views#The-views.
Python usually defines code blocks based on indentation, but since the
views do not require proper Python indentation, we need an alternate way to
define code blocks when the boundaries are not otherwise obvious -- so you
use {{pass}} to indicate the end of a code block. For example:
{{if some_condition:}}
This
{{else:}}
That
{{pass}}
Now we are outside the "else" block, so this line will always be displayed.
Without the {{pass}}, that last line would be part of the "else" block and
therefore only display conditionally. Typically, you would need a {{pass}}
to indicate the end of an if, else, elif, or for block in a view.

Re: [web2py] Getting wrong Results with my grading system
so if `perc >=90%, it is grade `A`? The code should reflect the same
then. Right now, it is `A`, if `perc >= 100`, which is not a valid value
for `perc`.
Am guessing the same is applicable for the `average` check too.
