Make sure you installed web2py_src.zip (the source). You have to be in the 
web2py folder to execute that command.

Re: compute not working on update

Anthony — 2012-05-26T04:35:32

Here's the DAL code: 
http://code.google.com/p/web2py/source/browse/gluon/dal.py#7228

try:
    new_fields.append((ofield,ofield.compute(Row(fields))))
except KeyError:
    pass

So, it calls the compute function with whatever fields are submitted in the 
update. If the compute function tries to access a field that's not 
included, it will throw a KeyError, which will silently pass.

Trouble running from source

RKS — 2012-05-26T04:20:00

Docs say run python2.7 web2py.py in the terminal and all I can get is the 
error:

/Library/Frameworks/Python.framework/Versions/2.7/Resources/Python.app/Contents/MacOS/Python: 
can't open file 'web2py.py'

Maybe I put it in the wrong place where it can't find it?

Re: compute not working on update

So if the computation needs two fields and only one is updated, it won't 
execute on update. It makes sense when I rethink the logic, but I wouldn't 
have thought of this right away. I recommend mentioning this explicitly in 
the book.

I see this as one of those little things that can cause a lot of 
troubleshooting and then a grumbling facepalm, an hour or two later :)

I am afraid I was unable capture the stack. 

any clue as to how I can run a python process and keep communicating with 
it during execution of web2py forms. If so I can send and receive the 
commands and data to webpy.

Thank you,
Janath

Thanks Simon and Anthony for the quick replies.    This is a controller and 
I'll try the suggestions.

Re: compute not working on update

Yes, I guess to be more clear, it should indicate that on updates, it tries 
to compute the value using the fields being updated. If one of the fields 
required to compute the value is not included in the update, then the 
compute won't be updated. Note, the compute should happen as long as it 
doesn't require any fields that are not being updated. So, this should only 
be a problem if the compute requires multiple fields, and some of them are 
being updated and some are not. To accommodate that case, though, the DAL 
would have to retrieve the existing record from the db in order to get the 
current values of the fields that aren't being updated. Of course, you 
could always do that explicitly in your code and then include those fields 
in the update as well.

Re: compute not working on update

peter — 2012-05-26T02:13:45

Thanks yet again Anthony. It makes sense that it only recomputes when the 
relevant fields change. I think it would be valuable to change the book as 
it implies (at least it did to me) that the computed value is computed on 
any update of the record, 

"When a new record is modified, including both insertions and updates, if a 
value for the field is not provided, web2py tries to compute from the other 
field values using the compute function. "

Well, in this case, you update the "title" field, but the compute depends 
on the "file" field, so there would be nothing to update.

There are legitimate uses, so I'd say leave it, or at least maybe just 
rename it so the functionality is still available (e.g., update_row).

Re: How to never return html?

Anthony — 2012-05-26T00:26:49

Is "api" a controller or function? Either way, you can prevent html 
requests by (a) making sure there is no .html view file associated with the 
particular function and (b) making sure you don't enable the generic.html 
view for that controller/function. For example, somewhere in the controller 
or function:

response.generic_patterns = ['xml', 'json']

Also, are you hoping to default to an xml response without having to add 
the .xml extension to the urls? In that case, somewhere in the controller 
or function, you could do:

if request.extension not in ['xml', 'json']:
    response.view = '%s/%s.xml' % (request.controller, request.function)
    request.extension = 'xml' # only needed if you have enabled generic.xml

anybody ever try to do modal registration using only web2py and recaptcha?

weheh — 2012-05-25T23:56:52

I'm trying to do modal registration with a custom form, recaptcha, and an 
ajax follow-through after processing. Recaptcha may have sunk this 
approach. Can you suggest a secure alternative that works better with 
jQuery? Or perhaps give your account of how to do modal registration in 
web2py?

Re: recaptcha in LOAD

For completeness, please refer to:

https://groups.google.com/forum/?fromgroups#!searchin/web2py/recaptcha$20load$20ajax/web2py/eeMT2Bb-KYA/7G6WZ-XeIygJ

This is an old issue and I'm late to the game, but with my modular approach 
I'm seeing that pbreit has already explored this 
javascripted-initial-authentication territory and declared it inhospitable.

Basically, if I'm to understand, you can't use Recaptcha with LOAD(..., 
ajax=True). Am I right?

Re: Who are logged in?

Alan Etkin — 2012-05-25T23:38:29

Let's say that the action /default/loggedin.load/user/<id> updates the 
app's logged in list and returns an html list with their names.

Then you could use this in the layout.html view:

{{=LOAD(c="default", "f="loggedin.load", args=["user", auth.user_id], 
timeout=60000, times="infinity")}}

That should update the logged in users for both client and server with 60 
seconds intervals.

LOAD options are documented here<http://www.web2py.com/examples/static/epydoc/web2py.gluon.compileapp-module.html>
