[web2py] Re: Where should I put functions that are useful/common to muliple applications?
I suppose you could use URL(a=??) in order to share those files across apps although I think that's fairly uncommon. I find that I learn SQL even as I use DAL. But if you still do want to use raw SQL you can use the DAL's db.executesql() function. But you lose a ton of DAL functionality. --
[web2py] T function and database records - html entities
Hi all,
I'm using the T function to produce some text in a multilingual
application, but I'm facing a small problem. If i use T('Aller à') I
receive the exact same string but when using T(' blabla') I receive 'gt;
blabla'. In the second case the greater than sign is correctly rendered in
html entity whereas the letter 'à' is not. Am I doing something wrong ?
I have similar problems when putting text in a database table, some
characters are converted to html entities others not.
Any idea / comment welcome.
Thanks for your time.

Re: [web2py] Re: Enforcing - like gmail: first character of your username should be a letter (a-z) or number.
Hi Rob I hope Massimo will consider to incorporate this into Welcome. It is much to the credit of web2py that security is given top priority and it is apt that the default scheme should be a thoughtful implementation. A well thought out Auth configuration is useful to everyone and the fact that it mirrors Gmail makes it a notable feature. For those that don't like it, it is much easier to disable or water-down than it is to reinvent -- as this thread amply illustrates. Otherwise, as this is more of a configuration rather than an app, I would suggest uploading it as a recipe to web2pyslices. Many thanks, David --
[web2py] Best way to insert 200k records?
Hello: What is the prescribed method for doing large bulk inserts? I am using sqllite as my backend. Is it ok to just write a Python script that talks to the db directly or should the DAL be used?

Maybe you can face transaction size problems with this volume. Web2py, by default, just commits after a successful transaction.

[web2py] Re: Best way to insert 200k records?
You can enter either via db(query).insert(name=value, ...) or by a CSV file. Both are convenient. I suppose you could argue that CSV is convenient if your data are dumped from some other db without computing an intermediate value. If your data are less clean, perhaps, or you need to do some complex intermediate logic and computation on the fly to come up with a value to insert into the db, or just for all around flexibility, then db(query).insert(...) works great. Both are equally useful. I use both all the time. Mostly, it depends on the source of data and how ready they are to insert into the db without me having to muck with them. --
Re: [web2py] Best way to insert 200k records?

[web2py] Re: Where should I put functions that are useful/common to muliple applications?
CSS belongs under static. Packages and common routines belong under modules and are imported. You could have a common static and modules and symbolically link. I have never done that, but it makes sense. I suppose you could also put the CSS just about anywhere on the file system. And modules could be put under the python package library and imported from there. I haven't tried that, but seems like it would work.

IS_EXPR is an imported function, and runs in its own namespace. It doesn't see
your globals.
Rather than use IS_EXPR, you'd be better off writing a custom validator. An
added benefit of doing it that way is that you can include the overhead of
BADWORDS in the validator's execution code (not its init), so it only gets
executed when the validator is actually used.
Validators are easy to write. Choose a simple one from gluon/validators.py to
use as a template. I suggest IS_EQUAL_TO.

Big hat tip to: Udi Milo
These steps will enable a Web2py app that currently authenticates users
using username/password (or email.password) to add the option for users to
use their LinkedIn account instead. Once logged in, the app can access the
LinkedIn API to access user LinkedIn data.
*1. Go to LinkedIn.com and get your developer key and secret.*
*2. Create folder called web2py/linkedin*
Place files: linkedin.py, model.py, helper.py from
http://code.google.com/p/python-linkedin/
Also create a new file linkedin_wrapper.py this will glue LI api into
Web2py framework
In this add add:
from gluon.http import HTTP
try:
import linkedin
except ImportError:
raise HTTP(400,linkedin module not found)
class LinkedInAccount(object):
def __init__(self,request,session,key,secret,return_url):
self.request = request
self.session = session
if self.session.linkedin is None:
self.session.verified = False
self.session.linkedin = linkedin.LinkedIn(key,secret,return_url,
gae=request.env.web2py_runtime_gae)
self.session.linkedin.request_token()
def verify(self, verifier):
self.session.verified = verifier and self.session.linkedin.
access_token(verifier = verifier)
return self.session.verified
def login_url(self, next=/):
return self.session.linkedin.get_authorize_url()
def logout_url(self, next=/):
self.session.linkedin = None
return next
def get_user(self):
if self.session.verified:
profile = self.session.linkedin.get_profile(fields=['id',
'first-name', 'last-name','picture-url','industry'])
return dict(first_name = profile.first_name,
last_name = profile.last_name,
picture_url = profile.picture_url,
industry = profile.industry,
username = profile.id)
*3. In dal/db.py*
Just above auth.define_tables() add:
# create custom field 'username' for linkedin profile
# the data will be pulled by get_user() in linkedin_wrapper.py
auth.settings.extra_fields['auth_user']= [
Field('username', writable=False, readable=False),
Field('picture_url', writable=False, readable=False),
Field('industry', writable=False, readable=False),]
at the bottom add:
if request.vars.agent == 'linkedin' or session.linkedin:
from linkedin.linkedAccount import LinkedInAccount
auth.settings.login_form=LinkedInAccount(request,
session,
[[YOUR_LI_KEY]],
[[YOUR_LI_SECRET]],
'http://' + request.env.http_host
+ '/[[YOUR_APP]]/default/user/verify')
auth.settings.actions_disabled=['register','change_password','request_reset_password','retrieve_username']
*4. In your controller (assumed by dal code above to be called default.py)*
def user():
if len(request.args)0 and request.args(0)=='verify':
auth.settings.login_form.verify(request.vars.oauth_verifier)
redirect(URL('user', args='login'))
return dict(form=auth())
In your controller functions you can access LinkedIn API at auth.settings.
login_form.session.linkedin
eg auth.settings.login_form.session.linkedin.get_search()
# this function will enable users to login using their LinkedIn account via
http://.../[YOUR_APP]/default/agent
# and other users to use their username/password via http://.../[YOUR_APP]
/default/user
def agent():
redirect(URL('user', args='login', vars=dict(agent='linkedin')))

[web2py] computed fields are not executed with Table inheritance
Hi all, I've just discovered that the fields defined as computed in the
'upper table' are not executed in the table that inherits the fields.
The following is the definition of the upper table
pictures_fields = db.Table(db, 'picture',
Field(picture, upload,
uploadfolder=request.folder+'uploads/pictures', uploadseparate=True,
autodelete=True, requires=[IS_NOT_EMPTY(), IS_IMAGE(),
IS_UPLOAD_FILENAME(extension='jpg|jpeg|png'),IS_IMAGE(extensions=('jpeg',
'png'))]),
Field(normal, upload,
uploadfolder=request.folder+'uploads/pictures', uploadseparate=True,
autodelete=True, requires=[IS_IMAGE()]),
Field(thumbnail, upload,
uploadfolder=request.folder+'uploads/pictures', uploadseparate=True,
autodelete=True, requires=[IS_IMAGE()]),
Field('picture_desc', 'text', requires=[IS_TRIM(),
IS_LENGTH(140,error_message=T('Warning, description too long'))]),
)
pictures_fields.thumbnail.compute = lambda row: THUMBER(row.picture, 200,
200, name='thumb')
pictures_fields.normal.compute = lambda row: THUMBER(row.picture, 600, 600,
name='normal')
pictures_fields.picture_desc.label = T('Picture description')
What is wrong?

Re: [web2py] Re: Can't import external modules
Indeed I wrote the patch to allow raising a meaningful error if the module is not loaded. The action taken should be the same as before the patch i.e.: return super(_Web2pyImporter, self).__call__(name, globals, locals, fromlist, level) but the error from the call is raised instead of resulting in a stack trace ending in custom_import.py. Even with this exception stack trace can be misleading sometimes. I also experienced invisibility of modules. What I found is that creating an instance by doing: python web2py.py -S my_new_app works. While doing things by copying or hand sometimes make the modules directory content not importable...

Re: [web2py] Re: Enforcing - like gmail: first character of your username should be a letter (a-z) or number.
IS_EXPR executes the expression in an environment that only contains the
value being validated (but not any other globals defined in your model).
For this to work, you would have to include all of the necessary code in
the expression (i.e., the definition of badlist and BADWORDS). A better
option is probably a custom validator.

Re: [web2py] Re: Enforcing - like gmail: first character of your username should be a letter (a-z) or number.
*Question:* Would it be worth considering an actual validator for username and user-like fields. *IS_LIKE_GOOGLE* IS_LIKE_GOOGLE validator enforces a username policy similar to Google Accounts (as of 2012), min 6 - 30 characters, only letters (a-z) and numbers (0-9), and periods, can't start or end with a period, can't have consecutive periods, and of course can't exist in database. Note: if an optional IS_LIKE_GOOGLE(db, 'table.fieldname') - then any user created user type field would be validated, Not a bad idea, but I would make it more generic and configurable, much like the IS_STRONG validator for passwords. Maybe something like IS_USERNAME, and have it take several arguments to configure the various validation options (including ability to provide a custom bad words list, and custom error messages for each potential problem).

[web2py] Re: Best way to insert 200k records?
10 minutes is all right. Still, if there are two methods and they are qualitatively equal apart from speed, I'd prefer to use the faster one. So posing the question, once again, is there a compelling reason to use the DAL for bulk uploads. More specficially, what extras, if any, are being added by the DAL for inserts that a bulk insert using SQLLite directly won't add?

Is correct if you are not doing this often - e.g., it might take 10 minutes as opposed to 1 minute without DAL (just assuming, not based on any actual measurement). So what? If you do this once an hour, then DAL processing and the individual record insertion (even if you use bulk_insert or csv) might make it too slow for you, and you would be better off looking at your database's native bulk loading facilities. --
Re: [web2py] Re: Back-and-forth between DAL SQLAlchemy
It depends on context. Web2py DAL is closer to SQL than on ORM. Assuming
db.define_table('person',Field('name'),Field('email'))
you have two options:
1)
db.define_table('message',Field('body'),Field('recipients','list:reference
person'))
for row in db(db.message).select(): # one select
for recipient in row.recipents:
print recipient.name # one select per recipient to get name (lazy)
2)
db.define_table('message',Field('body'))
db.define_table('recipient',Field('message',db.message),Field('person',db.person))
for message in db(db.message).select():
for recipient in message.recipient.select() # one select/message
print recipient.person.name # one select/recipient
or with a single select using joins:
for row in
db(db.message.id==db.recipient.message)(db.recipient.person==person.id).select()

Hi,
I found the answer to this question, so if anyone else is looking for an

in your model you need to just add 'id' to the to your primary field here
is an example.
db.define_table(
'product',

your other fields as usual
notice the 'id' which web2py then knows that this should be treated as the

[web2py] Re: Where should I put functions that are useful/common to muliple applications?
I guess it is referring to the packing/installation of *.w2p files via the admin interface. Only files under the app's dir would be packed, therefore site-packages would have to be installed outside that mechanism. By using Dropbox you are not relying on the admin interface for the mentioned portability feature. On Friday, August 17, 2012 9:38:26 PM UTC+1, curiouslearn wrote: Thanks pbreit and weheh. I looked at the link give by pbreit. It says the following: applications requiring site-packages are not portable unless these modules are installed separately. What exactly does it mean they are not portable? For example, as of now my application which lives in a dropbox folder synced with pythonanywhere, works great on pythonanywhere. Would that stop working? Thanks. On Friday, August 17, 2012 8:22:43 AM UTC-4, weheh wrote: CSS belongs under static. Packages and common routines belong under modules and are imported. You could have a common static and modules and symbolically link. I have never done that, but it makes sense. I suppose you could also put the CSS just about anywhere on the file system.

[web2py] Re: Best way to insert 200k records?
if it is a one time data load and i have the proper constraints set in SQLLite, i would use raw SQL. if this was repetitive use and i wanted to use web2py validation i would use the DAL with bulk insert (making sure that i validate the data before adding to the insert queue) On Friday, August 17, 2012 12:38:56 PM UTC-7, Mike Girard wrote: 10 minutes is all right. Still, if there are two methods and they are qualitatively equal apart from speed, I'd prefer to use the faster one. So posing the question, once again, is there a compelling reason to use the DAL for bulk uploads. More specficially, what extras, if any, are being added by the DAL for inserts that a bulk insert using SQLLite directly won't add?

Is correct if you are not doing this often - e.g., it might take 10 minutes as opposed to 1 minute without DAL (just assuming, not based on any actual measurement). So what? If you do this once an hour, then DAL processing and the individual record insertion (even if you use bulk_insert or csv) might make it too slow for you, and you would be better off looking at your database's native bulk loading facilities. --
[web2py] Re: Where should I put functions that are useful/common to muliple applications?
curiouslearn I agree it's a good idea to learn as much as you can about the underlying database. That said, you need to learn about sql injection and perhaps other MySQL attack vectors before making your application public. See, for example xkcd.com/327/ On Friday, August 17, 2012 12:17:48 AM UTC-4, curiouslearn wrote: Hello pbreit, Thanks, I will look into that. After posting I realized, I have the same question for css style files and js files. Where can I store those? Can I just store them in one application, and call them using URL() function? Is that the best way, or is there something better? I am new to tools and technologies related to web-development (MySQL) being one of them. For some reason I have this feeling that it is important to have some basic knowledge of SQL and to learn how to handle some database (in this case MySQL) using the standard commands it provides. Hence, for practice I decided to make my apps using raw SQL. Thanks again for your response. Hope you or someone can suggest something for css/js files. Thank you.

[web2py] Re: Web2py GAE strange error type 'exceptions.IOError' [Errno 13] file not accessible: (jQuery.js)
response.include_file() outputs the files that were added to response.files
(js, css). when you remove that you loose the auto output of files that
were added to response.files along the way.
response.include_mete() works much the same for HTML meta properties.
can we see the resulting HTML in both cases? in the first case (when it
fails completely) you get HTML right? but jquery.js fails to load so other
things on your site might break. in the second case it sounds like jquery
does load, but you are missing other files so your site breaks? or do you
get no HTML to the browesr in either case?
as an aside - how is threadsafe working for you on GAE? i had some
problems with it myselfperhaps i have bad code. :)

in your model you need to just add 'id' to the to your primary field here

db.define_table(

your other fields as usual
notice the 'id' which web2py then knows that this should be treated as

It would be nice If someone can tell me what is going wrong or if I can
get information on what files are included in the following statements
response.include_meta()
response.include_files()
My application runs (with limited layout features probably because of not
including the meta and add on files) if I edit the web2py_ajax.html file to
:
script type=text/javascript!--
// These variables are used by the web2py_ajax_init function in
web2py_ajax.js (which is loaded below).
var w2p_ajax_confirm_message = {{=T('Are you sure you want to
delete this object?')}};
var w2p_ajax_date_format = {{=T('%Y-%m-%d')}};
var w2p_ajax_datetime_format = {{=T('%Y-%m-%d %H:%M:%S')}};
//--/script

[web2py] Re: IS_IN_DB cannot pull the data from the table
Please open a ticket pointing to this thread. Will look at it asap.

I finally figured this should be a bug on the current in trunk version
(Version 2.0.0 (2012-08-15 17:30:38) dev)
I can pull the data when the data in primarykey field begin with numeric
numbers for example 12345 or 1ABCDE (See NG-1,2.jpg)
but cannot pull the data begin with alphabet like A1234. (See OK-1,2.jpg)

Try what the book says, 'name' is simply the name of the field you wish

[web2py] Major speed improvement need testers
There are two major speed improvements in trunk and I am not sure whether
they should go in web2py 2.0 next week.
1) Lazy table (based on ideas from Bruno).
db = DAL(, lazy_tables=True)
db.define_table('person',Field('name'))
the table is instantiated only when db.person is accessed.
So with some care:
Field(, requires=) # LAZY (good)
db.table.field.requires = ... # NOT LAZY (bad)
Field('other','reference table') # LAZY (good)
Field('other',db.table) # NOT LAZY (bad)
this may be a big speedup.
2) There is a new implementation of class Storage. This is a most accessed
object within web2py and now it is 10x faster.
Yet I am not sure if this breaks something.
It would be great if you could try the nightly build (or trunk) and report
if you experienced any problem.
It would be even better if you could run some benchmarks of your code
before and after the changes suggested at 1).
