Not exactly, but assuming 'form' is a web2py FORM or SQLFORM object, you can 
add a class to it by adding a '_class' attribute. You can either do that 
when you first create the form:

form = SQLFORM(..., _class='Dialog-form')

or after it is created:

form['_class']='Dialog-form'

See http://web2py.com/book/default/chapter/05#HTML-Helpers.

The ../ refers to the parent folder of the current folder. So, if the 
current folder is /static/css, then ../ refers to static/. If your css is in 
/static/css and your images are in /static/images, then to refer to an image 
from a css file, you would do ../images/image_file, which is equivalent to 
/full/path/to/static/images/image_file.

[web2py] Re: How do I add JQuery UI to Web2PY

[JavierQQ]

Can I edit =FORM too?

is it difficult?
As a example I'm going to insert this
http://jqueryui.com/demos/dialog/#modal-form

and I have one view called 'regcliente.html'
that has this
{{extend 'layout.html'}}
Registrar cliente


Cliente
{{=form}}



can I do =form(_class="Dialog-form")? (Dialog-form is the id of
the example)

this is how I intend to put it folders
/static
  /css
/start
  jquery-ui-1.8.16.custom.css
  /images
..
  /js
jquery-1.6.2.min.js
jquery-ui-1.8.16-min.js
..

and in Layout.html I put the javascript here
 

and finally in the view I put the divs but it only appears without the
style

Is the something I missed?

[web2py] Re: The web2py grid/crud plugin you've always dreamed about!

[tomt]

Hi,

I have a question about using powertable.

When I try to build a powertable on the following select:
tasks=db(db.task.cpaid==3).select(db.task.cpa,db.task.description,db.task.ls_js)
I get the following error:
  File "/home/xa21/workspace/web2py/applications/cpa4/models/
plugin_powertable.py", line 219, in __init__
_id = record.id
  File "/home/xa21/workspace/web2py/gluon/dal.py", line 3786, in
__getattr__
return self[key]
  File "/home/xa21/workspace/web2py/gluon/dal.py", line 3777, in
__getitem__
return dict.__getitem__(self, key)
KeyError: 'id'

I suspect this means that powertable requires a field named 'id'. Is
this true, or is there a way I can get around this?
(The table I'm interested in displaying is a legacy table that doesn't
contain an .id field)

[web2py] Re: How to redirect user to original url he asked after login

[Massimo Di Pierro]

In the crud case

cud.create(...,next='action/[id]')

automatically fills in the id of the record being created.

Auth allows you to the same when a new user is created.

[web2py] Re: How to redirect user to original url he asked after login

[Massimo Di Pierro]

There are cases when the original "next" got lost. I did not full
track the cause of the problem.
The code in Auth was a quick hack to handle it.

OK, now I'm seeing the book in French rather than English as well (only in 
IE, not Chrome). The HTML source code is in English, so I guess it is being 
translated client-side via plugin_translate. I see the following in the head 
of the HTML:

 
 

I assume fr.js shouldn't be there.

Note, I haven't made any changes to my browser. One minute everything was in 
English, and upon a new page load, suddenly French.

I am using recaptcha using the following code (public and private keys not 
shown):

auth.settings.register_captcha = Recaptcha(request, '', 
'yy', use_ssl=False, error_message='please complete the reCaptcha')

I've registered with recaptcha.net and I not running this from a localhost. 
 Also, the above line is called after auth is instantiated.  The rest of the 
registration page looks right, but the recaptcha box does not show up.  Any 
ideas?

Re: [web2py] My Journey to web2py

[Michele Comitini]

Read first 3 chapters of web2py book  then start right away coding
with web2py do not waste time , look at the examples and search
through the web2py user group messages; most of what you are trying to
do has been already answered.


Don't learn OOP from Java books you would learn the partial OOP
implementation of Java.
Smalltalk, C++ are better, but since you have little time you can
learn python and OOP in one pass.

See some good advice here:

Not about the book itself, but apparently fixed now.

All Google search hits that referenced the book came with
"language=fr" appended as a var.

I notice that the book does not rank high in Google searches.

Very strange.

[web2py] Re: How to redirect user to original url he asked after login

[Anthony]

Sounds like this will be completely re-thought, so maybe comments on the 
current (trunk) code aren't necessary, but here are some observations (not 
sure if these are correct because I haven't tested anything, just quickly 
looked at the code):

   - It still looks like _auth_next will be the first URL visited during the 
   session, whether or not it requires login, but then it can't get 
   overwritten. So won't the redirect end up going to the first URL of the 
   session rather than the last URL right before login (we want the latter, 
   no)?
   - _auth_next is reset to None if it starts with the current URL, but 
   don't we want it to be an exact match for the current URL (including args 
   and vars) in order to conclude that the redirect has happened?
   - I'm not sure I'm following properly, but does this involve an 
   additional redirect -- one immediately after login, and then another when 
   that redirect hits Auth.__init__?
   - This is repeated many times:

if is_relative(next):
next = self.url(next.replace('[id]', str(form.vars.id))) 

Instead of the is_relative function, how about a replace_id function that 
checks for a relative URL and does the replace? So, the above would just be:


next = replace_id(next,form)

Re: [web2py] SmartGrid and authentization required for view and edit actions ... why?

[Bruno Rocha]

I guess

SQLFORM.smartgrid(..., user_signature=False)

should not ask for user signature

but I do not recommend as your actions will be exposed for logged out users,
and you will not b able to track the changes or apply crud permissions.

[web2py] Re: problem with updating Form with writable=False Fields

[pbreit]

Just wanted to check if you know that Web2py that comes with a complete 
registration/login capability that works pretty well. You don't have to do 
any coding.

[web2py] Re: problem with updating Form with writable=False Fields

[Alex]

actually it's now working, I don't know exactly what was the reason
(I'm using record = db.auth_user(id))

when I output db._lastsql after form.accepts I see that all fields are
updated, not just the password field. How can I change it that only
the password field is updated in the sql statement?

[web2py] Re: Adding radio buttons to customised form in web2py

[Anthony]

It's not in stable yet, but in trunk, you can now specify ul or divs style 
rather than table style for the radio widget. I think it would be:

db.payment_bpay_step1.selection_type.widget = lambda f, v: 
SQLFORM.widgets.radio.widget(f, v, style='divs')

You can also create a custom widget, as described at the end of this 
section: http://web2py.com/book/default/chapter/07#Widgets.

When you say you want the "innerhtml" to be different from the value of the 
radio button, are you talking about the label next to the radio button? For 
that, the IS_IN_SET validator takes a 'labels' argument, which is a list of 
labels associated with the options in the set.

I have removed the "extend layout.html" directive in all my layout

The reason I'm asking is because I'm looking for a way to modify
SQLFORM.grid in sqlhtml.py to get the icons to show up on the buttons
properly whether or not jquery-ui is loaded or not.  By default
SQLFORM.grid tries to use jquery-ui for the user interface.
 base.css in
web2py has a number of icons in an image map that provide the
images on
the buttons if jquery-ui is not installed.  The jquery-ui has an
image
map with the same icons names (at different locations) that
provide the
images if jquery-ui is availalbe and ui='jquery-ui' (the default) is
provided on creation of SQLFORM.grid.  The image map name differs
in the
two scenarios, but the image names are the same.

So, if I could figure out in SQLFORM.grid if jquery-ui is
available to
the app, then I could provide the proper image map name and get
the icon
names/locations set properly.  In addition, it appears that the
text of
the A element needs to be formatted differently depending on
whether or
not jquery-ui is used (and some other css needs to be applied).

All of this is a long drawn out explanation of why I want to be
able to
figure out, in SQLFORM.grid in sqlhtml.py whether or not jquery-ui is
available for me to use.  I was kinda hoping there would be
something in
the request object that would help me out, but I haven't been able to
find anything.

Sorry if this is confusing, I'm up late again (yes, I'm an old

[web2py] Adding radio buttons to customised form in web2py

[Brent Jacobs]

I'm trying to display a field as a radio button group in a customised
form.  I want to place each radio button on a different row in a
table.  The problem is when I use `{{=form.custom.selection_type[0]}}
`, the widget is wrapped in unwanted `tr` and `td` tags.

Is there a way to add only the radio input field without the
additional tags? Also, is it possible to have the innerhtml different
from the value of the radio button?

Thanks.

My view:

{{extend 'layout.html'}}
{{=form.custom.begin}}

  
 {{=form.custom.selection_type[0]}}:
 {{=form.custom.widget.biller_list}}
  
  
 {{=form.custom.widget.selection_type[1]}}:
 {{=form.custom.widget.biller_code}}
  

{{=form.custom.end}}

Example of what's happening in the html source code:


  
 From my biller list:
...
  
...


My model:

db.define_table('payment_bpay_step1',
Field('selection_type', 'list:string'),
Field('biller_list', db.biller, notnull=True),
Field('biller_code'),
Field('biller_name'))
db.payment_bpay_step1.selection_type.requires = IS_IN_SET(('From
my biller list', 'Search by biller code', 'Search by biller name'))
db.payment_bpay_step1.selection_type.widget =

The old logic saves a next link in session in Auth(). What's that for?

[web2py] Re: problem with updating Form with writable=False Fields

[Alex]

I forgot to mention the following: I create the row myself because I
simply want to change the password:
id = auth.user_id
record = Row()
record.id = id
record.password = ''

this row is then passed to SQLForm. If I do this instead:
id = auth.user_id
record = db.auth_user(id)
record.password = ''

the form.accepts tries to update all fields. But I would only like to
update the password field and not modify any other fields.

[web2py] problem with updating Form with writable=False Fields

[Alex]

Hi,

first of all, many thanks to Massimo and all other contributers.
web2py is an amazing framework and exactly what I was looking for.
Keep up the excellent work!

I've got a couple of questions and problems so I'll start with the one
which is bugging me the most:
I've defined the auth_user table, added username, password and some
other fields. So far everything works fine. Now I want to create a
form where the user can change the password. In this form I do not
want to modify any of the other fields. So I'm doing the following
before creating the SQLForm (user_table == db.auth_user):

for field in user_table.fields:
  if field == 'password':
user_table[field].readable = user_table[field].writable = True
  else:
user_table[field].readable = user_table[field].writable =
False

this works fine, the form only contains the password field. But when I
submit the form, I end up with the following error:
File "C:\Tools\web2py_src\gluon\sqlhtml.py", line 1202, in accepts
fields[field.name] = self.record[field.name]
  File "C:\Tools\web2py_src\gluon\dal.py", line 3777, in __getitem__
return dict.__getitem__(self, key)
KeyError: 'registration_key'

so its trying to update a field which is writable==False. When I look
into the code in sqlhtml.py (line 1200) this is confusing me a little
bit:
for field in self.table:
  if not field.name in fields and field.writable==False:
if record_id:
  fields[field.name] = self.record[field.name]
elif self.table[field.name].default!=None:
  fields[field.name] = self.table[field.name].default

why is it checking writable==False? shouldn't it test for
writable==True or do I get something wrong here?

That's great. Thank you.

I agree with that. I think we may have to release 1.99.1 with the

@sagar: FWIW, this is what I usually do:

Also, note that your 'results' dict will only persist for the duration of a

Do you find markmin semantically rich-enough for writing books like web2py one?

I wonder about footnotes, more complex tables, more subsubsections...

It seems to me that there are two issues here. One is cleaning up the logic to 
make it uniform, DRY and understandable. The other is deciding where to put the 
next link (and doing proper validation of the URL).

I understand (I think) the basic use case for @requires_login, I think. 

What's the use case for saving the return link in Auth()? 

Does it make sense to try to save a next link in cases like change-password? 
Profile editing? 

I'm fine with reverting for now, but I really think that this logic is due for 
a review and cleanup. Maybe starting with a spec: what are we really trying to 
do? And how do these dynamic _next links relate to the various next-URL links 
in auth.settings?

Yes. Python uses reference counting. Every variable is a pointer to a
memory location. It keeps tracks of how many pointers point to the
same location.

a = A() # one pointer
b = a # two pointers
c = a # three pointers

when you delete one the counter is decreased

b = 4 # now two variables (a,c) point to A()

when the counter is zero the object is freed.

This works great UNLESS the objects have circular references (a.x=a)
AND the object has a destructor (A.__del__). As long a you do not use
destructors (who needs them?) everything works great.

Good question.

Our goals were:
- simpler then reST, similar to Markdown but more powerful
- support for HTML 5
- extensible
- avoid conflits with natural language as much as possible

In reST:
.. image:: images/biohazard.png
In Markmin
[[description  images/biohazard.png center 200px]]

In reST you cannot specify resize and location, works only for images,
there are weird .. :: all over the place. The Markmin syntax works
also for embedded videos.

I guess it go both ways.

Re: [web2py] Data stored in memory

I had read a little about that already, but found myself a little confused
as to when an object does or does not continue to refer to another object as
described in reference counts. At least you've confirmed I'm on the right
track. I'll go back to the books.

[web2py] Data stored in memory

[Chris Rowson]

Hi folks,

I'm trying to get my head around what happens to data stored in memory when
it isn't needed anymore.

Let me give you an example. Let's say I create a function which returns a
dict called 'results' populated with data from an external source each time
a user registers (for instance let's say it has data returned from geocoding
the users postcode and providing info about the area).

So the 'results' dict holds that data, it is used, and then what? Is the
memory automatically freed up again when we finish with the data or does it
hang around in memory?

I'm pretty new to python and web2py, can anyone help me understand?

Thank you!

Chris

[web2py] My Journey to web2py

[binaryghost]

Before anything else, I would like to introduce myself.

I am a passionate computer programmer.  I started to learn programming
thru Turbo Pascal and learned the essential concepts in C.

I learned C++ and Java in school but sad to say, I haven’t got a firm
grip on those languages even thinking in object-oriented Manner.

I have basic knowledge in RPG, VB.NET and SAP ABAP.

I’ve decided to be more serious in my craft and upgrade my skills and
learn most of technologies used to day.

I decided to focus on learning python before learning Java and C++/
directive C.

So I am here to seek your help and assistance in learning web2py.  I
will be working on a mini-project to create a simple project
management tool for our team.

To give you a basic idea of our requirement, our metrics database (in
excel format) is coming from a website.  We download the excel file
and extract data to it to come up with a meaningful information.  Our
team also update excel files which are stored in a shared network
drive to put updates on the development assigned to each one of and
submit it to our clients.  So my basic requirements can be summarized
into two:

1.  Download excel file from a website and extract and move the records
in a RDBMS database (for easy report generation ).  I’m planning to
solve this using irobotsoft and let python do the data extraction and
database updates.  Is there a better idea?
2.  A website that will let users meaningful information from this
database such as charts and excel grids.
3.  A website that will allow each use enter data in forms (like
creating an inventory system)

I only put the basic requirements since if I made these 3, the other
features will not a problem.

I made a research and decided to put my trust in web2py.  However,
this is my first time to create a useful website and I have no
knowledge in Python as well.  I’ve tried to skim the web2py book but
can’t think how to put things together to create a full working
website.

I’m here to ask for you help how can I get started building this
website.  I have basic knowledge in HTML only and know C.  Starting
today, I will be learning python by reading Wesley Chun’s Core python
book and will try to read some books related to OOP (most of them are
Java books).  I’m giving myself 2 weeks to learn python and will start
to work on this website and October and planning to finish it in a
month.
Any help and suggestions is highly appreciated.  In this thread, I’ll
be sending updates on the progress and ask questions in case I get
stuck.

Thank you in advance for all your support! 

[web2py] markmin vs. reST

[Gour-Gadadhara Dasa]

Hello!

I see that markmin is kind of 'standard' markup supported in web2py, but I use
reST markup and lot (even submitted feature request to Instant Press to support
it), but I wonder how does markmin, in general, compare with reST?

I noticed that there is no support for footnotes, tables look pretty simple...

Otoh, the web2py book is written in markmin...

I read 'Why?' (http://web2py.com/examples/static/markmin.html), but wonder what
was e.g. wrong with reST which is quite strongly tied with Python community?

Gour
