[web2py] Returning a controller function with an integer causes Thread issues
Hi I was working on the a controller function where the end result was the row id following a def insert_record() id= db[f].insert(**data) operaton return id As it turns out, this works without a hitch on my mac running python 2.7.10 and Web2py Version 2.9.12-beta+timestamp.2015.01.12.21.00.43, while on a Centos 7 machine with python 2.7.5 and the head web2py Version 2.12.3-stable+timestamp.2015.08.18.19.14.07, I could not for the longest time get the AJAX POST call to return the id of the inserted row from the Centos machine while it worked perfectly fine from my mac. After much frustration, I am happy to share that I have resolved this by casting the return id into a string: def insert_record() id= db[f].insert(**data) operaton return str(id) Sharing this if it helps save some one else some time!

[web2py] IOError(11, 'Resource temporarily unavailable')
Hi We have been experiencing the above error message particularly for calls which require more complex queries.

[web2py] Re: IOError(11, 'Resource temporarily unavailable')
I have an error handler within web2py that provides the error trace. One hypothesis offered was that nginx is closing the socket as uwsgi is taking too long to serve data. I've increased the keepalive_timeout parameter from 60 to 600 but this does not help. Where else could the problem be?

[web2py] db.Table no longer available in recent modularised DAL update
Hi
With the current version of Web2py (Version

standard_fields = db.Table(db, 'standard_fields',
Field('created_on', 'datetime', default=request.now))
results in the following error being thrown:
*** AttributeError: 'DAL' object has no attribute 'Table'
This used to work before (Version
2.9.6-stable+timestamp.2014.09.02.10.10.07)
Would this functionality be removed moving forward or is this an unintended
omission?
Thanks

[web2py] Selects as_trees
Hi
I am looking for a way to expand all referenced fields and have read about
the as_trees() method for selecting rows. I do not quite understand the
parent field requirement, but say we have the following
tables/relationships, was looking for a nested dict output which could be
JSONified as follows:
db.define_table('customers',
Field('name'),
Field('email'),
Field('address')
)
db.define_table('products',
Field('name'),
Field('description')
)
db.define_table('orders',
Field('customer', db.customers),
Field('order_date', 'date'),
Field('discount', 'double')
)
db.define_table('orders_line',
Field('order', db.orders),
Field('product', db.products),
Field('price', 'double'),
Field('qty', 'double')
)
db(db.orders_line.order==123).select().as_trees()
would give
[{'order':{'id':123, 'customer':{'id':1, 'name':'Bob', 'email':
'b...@demo.com', 'address':None}, 'order_date':'2014/01/29', 'discount': 0},
'product':{'id':1, 'name':'desk', 'description':'Wood finish, 4-legs'},
'price':100.0, 'qty': 1.0}]

Yes-you are right. I had meant XML object, but the issue still persists. Even with the XML() function wrapping the cache output, the output rendered on the browser is a string with the tags printed.

[web2py] Slow response
Hi guys, I have a fairly typical web2py application I am trying to deploy with a standard CentOS 6 configuration using Apache and MySQL. What seems to be bugging me right now is that the responses are very slow, around .7 seconds to load the home page. I have a feeling this is because of my apache WSGI setup. It seems that web2py doesn't stay running as a process on the server, so i guess each time it has to reimport and load everything up, seems quite slow. Before when running using the Rocket sever for development the site was snappy, now it's slow. Any tips/tricks to keep web2p in the background for wsgi so that it's not so slow?

[web2py] Re: caching TAG()
Thanks Leonel! That works.
I ended up doing it as follows:
SMALL = lambda x, **kwargs: XML(TAG.small(x, **kwargs).xml())
cache.disk('Hello', lambda: CAT(P('Hello'), SMALL('World')), time_expire=100
)
However, with such an approach, the retrieved cache value is a string
rather than an XML object which means that I get the following output
Hello
smallWorld/small
as the rendered output rather than
Hello

Brando,
Thanks for working this out!
it would be good to make a web2py slice or add it to the documentation/ examples

Re: [web2py] Multiple Uploads using jQuery-File-Upload: Javascript/CSS Conflict?
I just wrote my own way to do it yesterday which worked great. I would
love it to go upstream.
It's just a standard file upload with the multiple attribute.
here's the entire thing: it spits out a form.
my db looks like this:
db.define_table('uploads',
Field('username', 'string'),
Field('filename', represent = lambda x, row: None if x == None else
x[:45]),
Field('up_file', 'upload', uploadseparate=True,
requires=IS_NOT_EMPTY()),
Field('up_date', 'datetime'),
Field('up_size', 'integer', represent= lambda x, row:
quikr_utils.sizeof_fmt(x) ),
Field('notes', 'text'))
my contorller
def submit():
import datetime
form = FORM(LABEL(File(s):), INPUT(_name='up_files', _type='file',
_multiple=''), BR(), LABEL(Notes:), TEXTAREA(_name='notes'),
BR(),INPUT(_type='submit'))
if form.accepts(request.vars, formname=form):
if hasattr(request.vars, 'up_files'):
if len(request.vars.up_files) 0:
files = request.vars['up_files']
if not isinstance(files, list):
files = [files]
for f in files:
print f.filename
up_file = db.uploads.up_file.store(f, f.filename)
i = db.uploads.insert(notes=request.vars.notes,
up_file=up_file,filename=f.filename, username = auth.user.email, up_date=
datetime.datetime.now())

Re: [web2py] Multiple Uploads using jQuery-File-Upload: Javascript/CSS Conflict?
:-) I was having a hell of a time trying to get all the AJAX examples to
work and well, none of it f***ing would. Yesterday I brewed an extra strong
pot of coffee and cranked this out.
Some of the code i would like review on, I am not sure how to properly
check for if there was an uploaded file or not, i have that weird is in
then len() 0 but i don't think it's the best.
Whoever is a maintainer/developer of web2py - could we integrate this
somehow?

Re: [web2py] Multiple Uploads using jQuery-File-Upload: Javascript/CSS Conflict?
instead of inserting it, you could write the file stream out to whereever
you want.
It's really just a python cgi module object. so you can use all
corresponding documentation to help
look at this SO answer

Are you saying that even if you have this:

You can submit a form that does not upload a file into up_file?

[web2py] Re: how to hide the [wiki] menu option in auth.wiki
I'm using web2py 2.7.4-stable+timestamp.2013.11.25.15.21.21 but it doesn't
appear that the patch for this is in yet.
However, instead of doing the removal of the Wiki link with jQuery on the
client, which is susceptible to being hacked by a savvy user, the following
may be more secure:
To the layout.html or equivalent,
add the following line
{{if auth.user and (not auth.has_membership('wiki_editor', auth.user.id)
andresponse
.menu[-1][0].m=='[Wiki]'): response.menu.pop()}}
before
{{=MENU(response.menu, _class='mobile-menu nav' if is_mobile else 'nav',
mobile=is_mobile,li_class='dropdown',ul_class='dropdown-menu')}}

[web2py] generic WHERE clause in DAL
I would like to suggest a generic query which could allow queries within the DAL framework for functions supported by the database but not web2py's DAL by feeding in the raw query as would be expected in SQL native to a particular database. While DAL hides alot of subtle differences in different database engines, most projects would be using a particular instance and hence, I think the code would be very straightforward and along the lines of: In dal.py def raw_where(self, value, op): db = self.db returnQuery(db, op, self,value) and so in a controller somewhere... def OPERATOR(self, first, second): return '(%s %s)' % (self.expand(first), self.expand(second)) db(db.table.field.raw_where(parameter, OPERATOR)).select() would be possible. -- --- You received this message because you are subscribed to the Google Groups web2py-users group.

[web2py] distinct keyword for SQLFORM.grid
Hi I have been struggling with how one could get just distinct records to show with SQLFORM.grid if the query passed to it involved more than one table? Doing an inner join tends to generate a lot of non-unique rows and hence it would be important to just filter out the unique ones. With select, there is support for the distinct keyword but this is not the case with SQLFORM.grid. Using the groupby keyword is one approach but this can get somewhat tedious having to specify the fields to group by in advance and hence, I would like to understand if the omission of support for distinct in SQLFORM.grid is by design?

[web2py] Override _autocomplete function
I have been using the autocomplete widget which makes is really convenient.
However, there are times where I would like to customise what is shown in
the SELECT say with a custom expression rather than being limited to each
OPTION being the value of the field in the row.
It appears that the autocomplete widget does not accept a lambda in place
of a field. However, I guess one approach would be to define a virtual
field which could then be listed on the option. However, in my usage
scenario, I am looking for a way to display full addresses in the SELECT
when the user starts to enter a fragment of the postcode. Given that
postcodes are expected at the end of the address rather than at the start,
the autocomplete will not match that. Also, I am not sure if it would be a
good idea to do this with a virtual field over a large addresses dataset.
So, as an alternative, I have been toying with a workaround in which I try
to override the autocomplete AJAX call. Say given a function/url /address,
I have the following in my controller:
def address():
if request.vars._autocomplete_address_postcode: return SELECT([OPTION(%s
%s % (r.addr, r.postcode) for r in db(db.address.postcode.like('%s%%' %request
.vars._autocomplete_address_postcode)).select()])
This however does not appear to run and I still get the default
autocomplete behaviour.
Any ideas?

Re: [web2py] How to restrict choices in an OPTIONS widget based on values in that row or the default value
Thanks Vinicius. I adopted your suggestion, although I really like the idea
of defining all the widgets at the model level and this approach does not
conform to it.
If say the constraint on continent was made on another table and selected
prior to this form, i.e. we know what it is before the countries form is
shown, I am wondering if there is a way to add a filter to the options
widget?

[web2py] SQLFORM widget support for wider range of input types
WHATWG (*Web Hypertext Application Technology Working Grouphttp://www.whatwg.org/ ) list a wide range of input types in * http://www.whatwg.org/specs/web-apps/current-work/multipage/states-of-the-type-attribute.html#states-of-the-type-attribute Could we update SQLFORM.widgets so that a whole range is implemented as currently only a subset of types are available? I believe this would allow developers to provide a better user experience for their applications. It may also be useful to enable a number of specific features such as pattern=[0-9] in iOS devices to enable different keyboards. I had a look at sqlhtml.py and believe this to be straightforward to do. --

as long as I have tested you can:
1) define your table with geometry:
db.define_table('mytab'
Field('geometry_name'),
Field('the_geom', 'geometry()')
)
2) than you can insert geometries in this way:
info = dict(
geometry_name = 'test',
the_geom = 'POINT(0 0)'
)
db.mytab.insert(**info)
I suggest you to manage your geometries using the power of python-gdal
useful for wkt/b conversion and not only
hope it could help
