[web2py] Is there a way to use an Alias for a COUNT() field
Having the following
def by_country():
count = db.procesados.idpublicacion.count()
rows = db().select(db.procesados.pais, count,
groupby=db.procesados.pais)
return rows.json()
It generates the JSON:
[{"pais": "", "COUNT(procesados.idpublicacion)": 236}, {"pais": "AE",
"COUNT(procesados.idpublicacion)": 3}]
Is there a way to assign an Alias to the COUNT field so I won't have that long
name "COUNT(procesados.idpublicacion)" in the JSON output
Thanks

[web2py] Re: Numbers Format
Hi Vinicius,
You mean I can use str.format() to format numbers with thousand
separators instead of my function ?, that would be great Could you
give me an example ??

[web2py] Numbers Format
In order to format numbers with thousands separator and custom number
of decimals, I created the following function and included it in my
"db.py" model so it could be accessed through the entire application.
def number_format(num, places=0):
return locale.format("%.*f", (places, num), True)
I use it my views like:
{{=number_format(x.vebamt,2)}}
It works great in my development environment, but after migrating it
to production (I am using a linode vps) the function doesn't work, I
doesn't give me an error, it just doesn't format the numbers.
Any ideas what could be wrong ? I searched the group for a solution
for formatting numbers and didn't find a previous post on this matter
Thanks for your help

[web2py] Re: Ajax sample function does not work on Update form
I solved the issue:
if I enter the function on the 'onkeyup' event on the input text like
this:
onkeyup="ajax('my_function', ['argument'], 'target');"
I get the error
But if I used the full path ('/application_name/default/function') it
works fine:
onkeyup="ajax('/palitan/default/my_function', ['lastname'],
'target');"
Thanks for your help, this got me for a few days

[web2py] Ajax sample function does not work on Update form
I am using a form very similar to the Ajax sample on chapter 3 to search for customers and once you see the results, you click on the record you want so customer id and name are added to the form fields on my main processing form. This works fine on my "add new" records form. I have another page to "update records", similar to the "add new records" page. On this form the Ajax doesn't work, when I call the Ajax function I get in the target div the content of the index page. After trying to see why it would only work in one page and the add and update records pages are similar I found the reason. On the update page there is an id on the url (to be read using request.args(0)) this causes the error, for some reason when there is an argument in that position the Ajax get confused and doesn't return the right results. I tried adding a "/21" at the end of my "add new" page url and the Ajax also fails, this confirms that this is the cause of the error. I guess somehow the Ajax gets confused with this Has anyone else experience this error ? Thanks for your help

Hi, the thing is that MySQLdb is not even working outside the Web2py environment. I haven't been able to make it work in the regular Python interpreter.

[web2py] Need help installing MySQLdb in Mac OSX
Has anyone been able to install MySQLdb in Mac OSX ??? I want to use it with Web2py but haven't been able to make it work. I've read a whole bunch of forums saying how hard it is, I've done everything I've reead about it without any results. I even used macports as recommended by my Web2py teacher but it didn't work either. If anyone knows a sure way on how to achieve this I would appreciate it. Thanks for your time
