[web2py] Re: st_dwithin

[Pierre]

Great !!

I'd prefer to use Web2py api instead of executesql but I've read the latter 
is faster (speed might be a concern in my case). I'll do the modifications 
you suggest and see if it works. I hope this won't corrupt Web2py magical 
harmony

thanks

[web2py] Re: Does web2py set automatic cookies?

[Leonel Câmara]

Note that if you're talking about European rules you probably don't need to 
inform your users (In my case whenever I thought I needed I didn't) as 
there are exceptions to the rules. What I found is that the cookie warning 
is idiotically overused in many places where it isn't needed. For instance 
the login/remember me you refer is specifically exempt.  
  
In fact if you're not using the cookie for tracking anything in particular 
you can claim the cookie is a strictly necessary one to detect repeated 
login attempts and csrf prevention which is also exempt.  
  
Seriously, check the exceptions, I wish more website owners did because I 
hate those cookie warnings.

[web2py] Re: Problem define model class to model dal table no guide

[Alessio Varalta]

This solution for me is not good. Ok in this case work but virtual field 
allows only simple operation on the single filed of a table. I want class 
with function where i can use cicle and where i can use another dal 
object..This is present for all frameworks java-ruiby!!! for 
exmpale

Class Person extend Model
  string name,
  int age ecc..
  function calculateNationOfPerson(id){
Nation nation=new Nation('all')
return nation.find_nation_of_person(id)
  }
}

Don't analyse the exact syntax is only a exmpale
So if there is any possibility to create a class with function where you 
can use also the other tables? Only solution that I have find is to create 
a file module that have the name of the table and where i put all 
function...This is not a good solution but i see only this!
In Java-Ruby the model class are a rapresentation of the object database so 
you can use the model class for the logic for exmpale 
http://guides.rubyonrails.org/active_record_basics.html, implment function 
and use this in the controller. So I see the class in web2py but don't 
class that represent the model so I think is impossibile!Put all logic in 
controller? Create module with many functions??

A virtual/method field can be as complex as you want it to be, and it does 
not operate on only a single field of a record. Rather, an entire record is 
passed to it. Furthermore, method fields can take additional arguments and 
of course have access to any global objects as well. Perhaps you are 
confused because the functions of virtual/method fields are often defined 
using lambdas, but you could instead define a separate function using "def" 
and then specify that function in the definition of the virtual field.

I don't see how you would *need* a class for anything you want to do. You 
could simply create functions and pass the records to the functions (the 
DAL method fields are just a convenient way to attach such functions as 
pseudo-methods of the record). If you want a way to organize a set of 
related functions, you could still create a class and just define a set of 
static methods.

If you want an ORM, you might try the weppy ORM or SQLAlchemy or another 
framework altogether, but the web2py DAL is simply not an ORM and is not 
going to be. Nevertheless, it is not clear why you would need an ORM or 
classes to do what you want to do.

I don't know exactly what the above is attempting to do, as the data model 
of nation is not clear (i.e., is "id" the id of the Person record, and if 
so, how does the Nation object use that to find the person's nation?), so I 
won't attempt any web2py code. But in principle, I don't see why you 
couldn't define a similar function and just pass a web2py Row object to it 
(and optionally, attach it as a method via a method field).

[web2py] Re: submitting the form when updating .load file

[Jason Solack]

Sorry i'm not clear!  I'm trying to break up a reporting site and my 
initial idea was to use several LOAD components where in the past i was 
using ajax calls.  I like the component framework as it seems i can return 
HTML templates... it just feels cleaner.

I have this component within the form, but i could keep all the components 
outside the form if that is required to have them passed to their 
corresponding controller.

Another quick question on components.  Is there a way to wait for them to 
be loaded until called upon or must they be all loaded on the initial page 
load?

Thank you for your help

I've done this several ways... the actual HTML generation could be via

bootstrap or jquery ui to help out creating tabs... using a library helps 
the process of making tabs pretty trivial...

here's jquery ui's information

Re: [web2py] Re: web2py and python3

[Alex]

I'm still missing a clear strategy from the devs... I could understand if 
you don't have enough resources and ask for help (web2py is open source and 
anybody can contribute after all). But saying that python3 is useless and 
nobody wants it is not a good approach.

It seems like most of you only deal with ascii characters. Only if you 
constantly deal with non-ascii characters you really feel the pain of 
python2. e.g. ajax request with user input, use string for mail.send or 
T(..).format(..) -> unicode error. Basically I have to test all user string 
input if it is unicode and convert to str

Still not quite clear what you are trying to do with the form (as it has no 
action nor submit button). Anyway, you can always manually load and/or 
reload a component as follows:

First, create a div:



Then load a component into the div via:

$.web2py.component('{{=URL('controller', 'function.load')}}', 'mycomponent'
);

Re: [web2py] problem while adding a radio button in login form

[Richard Vézina]

login form are part of web2py auth.form or something I haven touch that
since a wild... But you have to custom the form and login form is par of
controllers/default/user function... You then need to have a look at the
book to how customize login form...

You may also just try to set readable=True and writable=True on your field
definition it may works... But I am not sure...

[web2py] Re: submitting the form when updating .load file

[Jason Solack]

So in this case i was just wanting to see if the form was submitted when 
reloading the component via:

jQuery('#test_div').get(0).reload()


and by printing the request.vars to the terminal i saw that it wasn't.  I 
will try your method $.web2py.component and see what results

[web2py] custom download function

[Joseph Faulkner]

I'm developing a simple webapp in web2py and I want to create a link that 
let's the user download a file. Like this:



However, I want to do this without having to pass the FILE to the user in 
the page handler. I want to retrieve an ID from the server asynchronously 
that will correspond to the file I want to download an then pass it to a 
custom download function like this:

 

This way, I will be able to upload files to the server asynchronously, (I 
already figured out how to do that) and the download link on the page for 
that file will work right away without having to reload the page.

So, on the server side, I would do something like this:

def custom_download(): 
download_row = db(db.computers.FILEID == request.args(0)).select()
download_file = download_row.filefieldreturn download_file

However, I'm not entirely sure what I need to write in order for this to 
work.

[web2py] Pre-populated Forms

[Anthony Smith]

Hi All, 

I have a products table:
 db.define_table('product',
Field('product_name'),
Field('active_ingredient'),
Field('batch_no'),
Field('expiry_date','date'),
Field('product_type', 
requires=IS_IN_SET(PRODUCTTYPES),default= PRODUCTTYPES[0]),
Field('withholding_period','integer'),
Field('ESI_withholding','integer'),
Field('qty','integer'),
Field('date_purchased','date', default = request.now),
Field('purchased_from', 
requires=IS_IN_DB(db,'company.company_name','%(company_name)s')),
(auth.signature),
format='%(product_name)s %(batch_no)s')

I can edit the product with the following controller:
def edit_product():
product_id = request.args(0,cast=int)
product = db.product(product_id) or error()
if not product.created_by==me:
product.created_by.writable = True
else:
product.created_by.writable = False
form = SQLFORM(db.product,product,
   showid=False,
   
deletable=(product.created_by==me)).process(onsuccess=auth.archive)
if form.accepted:
session.flash="Edit Successful"
redirect(URL('products'))
return locals()

At times I need to add new products but only some of the fields change E.G. 
batch_no, expiry_date, and supplier. 
In short if need to add similar item that I already have in the products 
table 


thanks 

Anthony

Re: [web2py] Re: web2py and python3

[Pablo Angulo]

I also have to work with unicode all the time. While it's true that
python3 deals better with this issue, there is no way that web2py can
move to python3 and our current code keeps working, precisely because of
this issue. Our code has lots of .encode('utf8'), .decode('utf8'),
unicode(...), etc. We would have to migrate our apps to python3.

So a new framework that is based on the same ideas and part of the
existing code, as Massimo have said explicitely, is the only possible
strategy. But while we do the necessary porting of our code to python3,
we will also get other benefits in the deal. python3 being non-backwards
compatible forces a non-backwards compatible version of web2py.

you constantly deal with non-ascii characters you really feel the pain
of python2. e.g. ajax request with user input, use string for mail.send
or T(..).format(..) -> unicode error. Basically I have to test all user
