[web2py] Re: convert field to multiple view values?
This is a three step process:
1) disable JS validation as float for this field
form.element('input[name=height]')['_class']='feet'
2) create a custom validator that filters data in and formats data out
class FEET:
def __init__(self,error_message='invalid'):
self.error_message=error_message
def __call__(self,value):
# converts 3ft 4.5in input into 1.0287 meters for
DB
import re
match=re.compile((?Pfeet\d+)ft\s+(?Pinches\d+(\.\d
+)?)in).match(value)
if not match: return (value, self.error_message)
return 0.30480*(int(match.group('feet'))
+float(match.group('inches'))/12) #meters of course
def formatter(self,value):
# converts 1.0287 meters from DB into 3ft 4.5in output
feet = value/0.30480
feet, inches = int(feet), (feet-int(feet))*12
return '%ift %fin' % (feet, inches)
db.define_table('foo',
...
Field('height', 'double', requires=FEET()),
...
)
3) (optional but nice touch) create a JS validator for CSS class
'feet'
jQuery('input.double').keyup(function()
{this.value=do_something(this.value);});
you have to write the function do_something to parse ft and in and
output the proper formatting.

I'm new to web2py and the I did this previously was with javascript
but I was hoping to avoid that this go around.
In my database table I have a single field something like this below:
db.define_table('foo',
Field('height', 'double'),
In the controller/view I need to be able to translate that so when
viewing a record they see:
Feet, Inches, and Fractions of a Inch.
When adding a record it would need to be a text field for feet and
drop down lists for inches and fractions of a inch.
I know how to do that in javascript, but I don't like relying on
javascript if possible. I'm hoping there is a way to do this in the
controller or model.
Thanks for any suggestions.
[web2py] Re: web2py seems to lose session

[web2py] Re: web2py seems to lose session
Hello again Massimo, and thanks for the feedback.
I've been troubleshooting this all day long and i've tracked this down
to a view that i have that serves 2 images and two tables with
information from those two images.
That view is something like (the syntax is not this, just for
illustration purposes):
div
div id=1
img src=URL(.,f=generate_image,param=1) /
{{python code for the table using information on the
session...}}
/div
div id=2
img src=URL(.,f=generate_image,param=2) /
{{python code for the second table using information on the
session...}}
/div
/div
All the tables are ok, but only the first image appears. If i go call
the URL of the second image directly on the browser url textarea, or
using firebug, the second image appears ok. The only difference
between both images is a parameter that calls inside the default.py
the function generate_image, but one parameter generates one kind of
image, the other parameter other kind of image. The images use
information from the session.
So what i found so far is:
- both images called separately work fine
- one after the other gives problems with session things
- both images are called one after the other, but it seems that at the
second time, the session object isn't defined at the time of function
call, and if i do a kind of if (session.something is not None) and
give something like a alert image, web2py creates a new session file
and leaves the first session file in the session folder..
It seems, that the second time the method generate_image is called,
the session is still not ready. If i don't return nothing, web2py
works fine. If i do a 'if' inside generate_image to return an alert,
web2py creates a new session and leaves the other in the folder.
Is there any way of enforcing the session object to be ready when a
function in default.py is called? Even if that slows down the response
from the server..
I'll keep on exploring, thanks,
João Ventura

[web2py] Re: web2py seems to lose session
Hello again,
well, after an entire day (about 12 hours) around this, i just made a
final test with a controler and view something like:
img alt=1
src={{=URL(r=request,f='get_image',vars={'param':'1'})}} /
img alt=2
src={{=URL(r=request,f='get_image',vars={'param':'2'})}} /
img alt=3
src={{=URL(r=request,f='get_image',vars={'param':'3'})}} /
and sometimes just the first image appears, sometimes the 1st and the
2nd, sometimes the 1st and the 3rd, and very rare all... If i insist
on pressing F5 to reload the images very fast, web2py loses the
session, and creates another file in the session folder.
get_image is a very used controller, and after digging in some
foruns and in the web2py documentation, i've read something like
web2py has the session object locked, and maybe it is what has been
happening here: the first call to get_image locks the session, and
then the second can't access the session (maybe the browser parallels
the calls to the controler), and instead of waiting for the unlock,
web2py fails miserably. To go around this, i've added to function
get_image a session.forget(), so now it is something like this:
def get_image():
---session.forget()
---()
In the web2py book it is written this about session.forget(): It
tells web2py not to save the session. This should be used in those
controllers whose actions are called often and do not need to track
user activity.. If this kind of behavior is the purpose for
forgetting the session, maybe this should be better documented in
that section of the book (4.8 - session). To me, that sentence about

for the users. Or maybe i'm wrong in my conclusions, but the fact is
that now all three images (see code above) appear and the problem

[web2py] Re: web2py seems to lose session
I am not completely sure what is going on in your case but:
session.forget() only affects the current action and forces web2py to
release the lock on the session file and not save it. This affects
only the current action in the sense that if the session was a created
by a different action that did not call forget, the session is there
and any action passing the session cookie will be able to retrieve it.
There are two locks. One on the session file. One on the sqlite
database (imposed by sqlite itself).

the session is still not ready. If i don't return nothing, web2py
works fine. If i do a 'if' inside generate_image to return an alert,
web2py creates a new session and leaves the other in the folder.
Is there any way of enforcing the session object to be ready when a
function in default.py is called? Even if that slows down the response
from the server..
I'll keep on exploring, thanks,

[web2py] Putting too much logic in a view
I have a table with the following structure.
firstname string
stboolean
I can display the info with a view,
but I'd like to check/uncheck certain names
using the status check box, then delete
the checked names.
I feel I'm going about this the WRONG way
because most of the logic should be in
a controller, and views should mostly
only display the data.
Here's the view.
Thanks in advance!
table
{{ for r in recs : }}
tr
{{=TD(r.id)}} {{=TD(r.firstname)}}

[web2py] Keep the instance of a class during the session
I have a module (in my_app / modules) that defines a class MyClass. This class operates with model data. In the __init__ there is a heavy workload, and data are available for other minor calculations. What I want is to create an instance of MyClass [my_object = MyClass (...)] a function of my controller and can use this instance from other functions, to avoid re-do the calculations again. I analyzed the alternatives are: 1) Save my_object in session. This is discarded because session only supports saving simple objects. 2) Save my_object with pickle and load it to the other functions. 3) Save the state of the object in the database. I do not like. 4) ¿? How do you see this approach? What other alternative can be proposed? Regards Jose

[web2py] Re: Putting too much logic in a view
Perfect!
Thanks so much!
One thing I've been thinking about, is putting together a reference
database that
will help newbies learn from working examples.
As I browse the forum, I see people asking things such as
How do I populate a drop-down list from a table.
Providing a reference database would help give people actual
working examples of code that can be viewed and customized to fit
specific needs.
What does everyone think?
Again thanks for the GREAT example Mr. Freeze

[web2py] Quick fetch modification
I've just made a quick modification to the fetch function from gluon.tools and felt it might be worth posting. http://wklej.to/rLuT - I've pasted the code online since I didn't really have time for sending a proper patch (whatever would that mean for web2py - BTW, some guide about it wouldn't hurt). The main difference is that when not on GAE it uses httplib instead of urllib2, so it can use any HTTP method (including PUT and DELETE). It also lets you send data that is not urlencoded (some web APIs are based on JSON or XML, so I thought such a feature might come in handy. The first new feature is controlled by the method keyword argument. If it's value is not specified it behaves like it did before (POST if it sends data and GET otherwise). The second feature is controlled by the encode_data keyword argument (which defaults to True). PS. I'm affraid I didn't implement redirection handling. I'll get to it asap, but now it's 4 am in my timezone and I need some sleep right now. PPS. Since HTTPConnection.request accepts file-like objects as the requests body I think I should count that as implementing three features. ;)
[web2py] Re: Keep the instance of a class during the session
I depends on whether the data is different for each user of shared
between users.
In the latter case Thadeus is right: cache it. You can store any
object in cache.ram
value=cache.ram('key',lambda:function_that_computes_value(),expiration_time)
If the data is per user you can store it in session but you need to
pickle/unpickle it yourself.
