Excellent! Thank you both! Before I had [file | (cbox) delete ] requires=IS_IMAGE() got rid of the delete and checkbox, but now I am still left with [file] (a link to download the file) Might have to do server-side DOM parsing to get rid of that ... Thanks!!! Luis.

[web2py] Re: How to implement flags?
IMHO it depends on a number of things. Using groups and memberships is good if the flags are meant to indicate an ability to do something on the system because there are decorators and functions to test for having the attribute. You can then decorate a function or use a has_ test to determine ability in the code. If all you want to do is test something in code and there are a fixed and small number of these flags then an extension to the user table might be the easiest using a binary column per flag type. One problem is a new flag causes a schema change. It would be the most efficient, reading the user table could pull these in at the same time but that would be premature optimization. The relations in the auth_* tables look like this in ascii auth_user - auth_membership -- auth_group auth_permission where indicates a one to many relation. Therefore auth_membership is an intermediate or join table that realizes the many to many between auth_user and auth_group. The auth_permission table can be used to hold capabilities and not be associated with tables at all by means of a settings tweak. Then a permission can be assigned to only one group but a group can have several permissions. Then users can be assigned to multiple groups to collect the capabilities assigned by the admin. By using the group you can lump several flags that belong together. This works for me to define a hierarchy of users for the application I am working on. I am able to customize the permission items to whatever group type the installation needs to allow or disallow a group to have a certain capability without having to change what groups the users belong to, something like a policy editor as in this group can do these things. If all the flags are single purpose and are not grouped then I would think you could collapse this to a flag = group item. I am not certain of lists in columns. It is used with GAE to get around the lack of functionality in their DB but many db admins call it an anti-pattern called jay walking. The main difficulty is searching for a particular attribute in the list from a SQL perspective.

[web2py] orderby first, then limitby
I have a query that includes both orderby and limitby. What seems to happen is that the db returns some set of records as dictated by the limit and then orders the records in that set. So I pretty much get the same set every time even though I know the field being ordered has changed for various records. Is this how SQL works? Is there any way to order the whole set first and then return the sub-set?

[web2py] vars vs. kwargs
hi,
it is cosmetic, but can be a pain for someone no so familiar with
python.
In examples for restful api:
def index():
def GET(*args,**vars):
patterns = [
/persons[person],
/{person.name.startswith},
/{person.name}/:field,
/{person.name}/pets[pet.person],
/{person.name}/pet[pet.person]/{pet.name},
/{person.name}/pet[pet.person]/{pet.name}/:field
]
parser = db.parse_as_rest(patterns,args,vars)
if parser.status == 200:
return dict(content=parser.response)
else:
raise HTTP(parser.status,parser.error)
def POST(table_name,**vars):
if table_name == 'person':
return db.person.validate_and_insert(**vars)
elif table_name == 'pet':
return db.pet.validate_and_insert(**vars)
else:
raise HTTP(400)
return locals()
after copy paste everything is ok, but the problem is waiting to
happen ...
vars hides built-in vars function.
cheers,
pawel

In sql, you can apply first order by and then limitby for example in Oracle: select * from (select * from table order by field) where rownum11//row 1 to 10 after order On 9 jun, 09:52, pbreit pbreitenb...@gmail.com wrote: I have a query that includes both orderby and limitby.

I much prefer all cross-platform issues to be handled with the os and sub modules. Why can't we do that here? It seems we have no developer with Windows where is the problem. I am on Windows, still XP even. Is there a small zipped app that I could test quickly to see the problem? Sure, if you can debug code. Get code from the Mercurial repository. Debug and submit the patch to Massimo. Look for the problem described by Alessandro. You'll find the information you need on the problem on the threads named web2py 1.96.*x* is OUT. It is probably a bug with the code I wrote but I don't have a Windows machine to debug a problem specific to this platform. -- A+ - Pierre My blog and profile (http://pierrethibault.posterous.com)http://pierrethibault.posterous.com YouTube page (http://www.youtube.com/user/tubetib)http://www.youtube.com/user/tubetib Twitter (http://twitter.com/pierreth2) http://twitter.com/pierreth2

Limitby should be executed after olderby. Are you sure that is not the case? What DB? On Jun 9, 2:52 am, pbreit pbreitenb...@gmail.com wrote: I have a query that includes both orderby and limitby. What seems to happen is that the db returns some set of records as dictated by the limit and then orders the records in that set. So I pretty much get the same set every time even though I know the field being ordered has changed for various records. Is this how SQL works? Is there any way to order the whole set first and then return the sub-set?
[web2py] Web2Py RoR performances
Hi, I learned Web2Py and I'm learning Ruby on Rails. Is Ruby on Rails faster than Web2py ? It seems web2py open/read/close each files (db.py, controller...) to render a page (including all partials, layout...). Ruby Rails seems to cache all this files into memory, so it's faster.

Re: Re: [web2py] Re: web2py 1.96.4 is OUT
So you suggest removing the case insensitive flag that was added in 1.96.4?
Re: Re: [web2py] Re: web2py 1.96.4 is OUT
But in a web2py app, you would have something like /applications/Cast/modules/cast.py, and in your code you would just do 'import cast'. My understanding of the problem is that in that case, the new web2py importer tries to import applications.cast.modules.cast instead of applications.Cast.modules.cast, which results in an import error. In fact, I cannot actually reproduce that problem (Windows 7, Python 2.7, web2py 1.96.3) -- if I capitalize the name of the application folder, the web2py importer still appears to work. So, as far as I can tell, the importer works, even without the fix in trunk, though maybe I have misunderstood the problem. Anthony On Thursday, June 9, 2011 10:03:01 AM UTC-4, cjrh wrote: Ok, so here is the thing: it appears that on Windows, everything works if the capitalization of the import statement matches the capitalization of the folder structure. Consider this folder structure (and there is an __init__.py in each folder hierarchy): /app/Cast/inner/cast.py In my file /test_imp.py, these contents WORK: try: import app.Cast.inner.cast print 'Pass' except: print 'Fail' pass These contents FAIL: try: import app.cast.inner.cast print 'Pass' except: print 'Fail' pass If, however, I change the folder structure to this: /app/cast/inner/cast.py Then I get *exactly opposite results*. In other words, the capitalization of the import path in the python file and on the file system must exactly match. This is on Windows XP x64 SP2. I have attached my test. In my opinion, we should just document that the cast must match. Note that this issue has *nothing to do with web2py*, and as a Windows user, I am not too surprised by this behaviour anyway.

The issue seems to appear only when there is a repeated name in the chain. Could you test that too? My attachment has such a test-case ready to run. It seems that when a name is not repeated, the case-insensitive name matching works. This smells like a bug in Python, and probably needs to be fixed there.

Have custom form - using inpval, dspval, etc. and would like to know
if there is specific formatting that allows me to set form field
properties?
this part I get: {{=dspval.my_field_name}}
My question is using the custom.form, is there a notation that allows
me to do something like:
1. set the width e.g., style=width:200px;
2. set a form text field to be hidden instead of visible
3. assign a field validator e.g., IS_EMAIL

GAE prefers many fields to joins as you can't do joins there. lists for flags just seems unwieldy in either environment. bitwise operations seem super-slick and cool, but do they make the code harder to maintain? cfh

[web2py] Re: Question about superfish menu and roles
Yes, you can create whatever menus you want. The welcome app provides menus
that are described in a models file but you can describe a a different menu
or describe a menu in a controller or module. Just follow the patterns you
see in the welcome code:
response.my_menu=[(T('Resources'), False, None,
[
(T('Documentation'), False, 'http://www.web2py.com/book',
[
(T('Preface'), False,
'http://www.web2py.com/book/default/chapter/00'),
(T('Introduction'), False,
'http://www.web2py.com/book/default/chapter/01'),
]),
]
)]
And then in your view:
{{=MENU(response.my_menu, _class='sf-menu')}}
[web2py] Re: Web2Py RoR performances
This is probably not a discussion we want to start. While Python may have a small performance edge, it's nothing to get excited about. Likewise, the OP makes performance assumptions that may not be realistic. As I thought everyone knew, there are quite a few variables that go in to overall system performance. Database, caching and coding optimizations are as important or more than how the framework works. That said, Massimo and the group have demonstrated a commitment to performance so if you have any specific recommendations or, better, code, I'm sure they'd be happy to consider.
[web2py] Re: database access
We might more detail about what you are trying to do including some code samples.
[web2py] db.define_tables
Hi !
Below given is a table ---
code
db.define_table('ac',
Field('acnm','string', IS_LENGTH(100), length=100, required=True),
Field('acgrpid', db.acgrp, notnull=True, required=True),
Field('active', 'string', IS_LENGTH(1), length=1,
requires=IS_LENGHT(1), default='Y', required=True, notnull=True),
Field('homeunit', db.unit, notnull=True, required=True),
Field('showall', 'string',IS_LENGTH(1), length=1,
requires=IS_LENGHT(1), default='Y', required=True,
notnull=True),
migrate=False
)
/code
--- In the Field 'active', I have written --- required=True,
notnull=True.
From the documentation, the purpose of required is understood.
1) But where does notnull come in action? (whether in AJAX
validation or while DAL inserts or somewhere else).
2) For the Field 'active', I want to have a set of 2 values ('Y'
'N').
In FORM, the user would be able to select a value from these 2 values
ONLY. (default is 'Y').
How do I do it?
Thanks,
Vineet

'required' is enforced by the DAL, and notnull is enforced by the database
itself (it is equivalent to the NOT NULL SQL statement). Note, because
notnull affects the actual database table, I think changing it requires
migrations to be on.
2) For the Field 'active', I want to have a set of 2 values ('Y'

Use requires=IS_IN_SET(['Y','N']). In that case, you won't have to bother
with IS_LENGTH.

[web2py] Re: Web2Py RoR performances
Good point. The last thing we want is another Python vs RoR vs whatever war. I know that I helped test performance and ran my own benchmarks when Massimo was working performance improvements with regards to session files back in March, since sessions can slow down response times. My own testing found that my app, which is becoming quite large now, had an average response time of 30 ms (without database interaction, of course). I don't care what language or framework you use. If you can get a complex application (with db turned off and no performance tweaks) to give average response times of less than 50 ms, then it doesn't matter how the framework is rendering the files behind the scenes. I've never used RoR so I don't know if it truly is faster or slower, but even if it manages to shave a couple of milliseconds off the average response time compared to web2py by caching everything in memory, does it really matter? Your average response time is still well below 50 ms which is FAST! You will never see a difference between 30 ms and 28 ms. I doubt even Google or Facebook would care about a 2 ms difference. At that point, just use whatever you are most comfortable with.
Re: [web2py] Re: vars vs. kwargs
web2py makes extensive use of these. Take the A, DIV, or TABLE as examples, you can pass HTML attributes (e.g. _class, _id, _style) to these, but if you look at the code, you will notice that these things are not in the signature of these methods. They allow you to provide an unknown number of parameters to a method. For example: def my_method(text, _class='', _style='', _id='', _onclick='') Could easily be rewritten to: def my_method(text, **kwargs) Then kwargs is a dictionary with any extra parameters passed: if '_class' in kwargs: output += 'class = %s' % kwargs['_class'] Using *args on the other hand would be if you didn't expect named parameters to be used, just an unknown number of unnamed paramters. Hope that helps to clarify.

However when I try another application it gives me an error that it cannot find .../cache/ cache.shelve. This other application works okay with 'python web2py.py' on the same server. If I create a dummy file called .../cache/cache.shelve, it deletes this file, and then complains it cannot find it! I have given full permissions to both the directory and the file. The VPS uses Centos 5.5, and I am running things on python2.6.1, web2py version 1.96.3 any ideas? Thanks Peter

Yes, I checked that project, but these way would require not adding anything at the headers, and it also parses the models file. It requires no modification in web2py, just in Pydev.
