[web2py] embedding web2py forms in static websites
I want to embed web2py forms in a static website (same domain) and keep the
static part as simple as possible.
Currently I have this in the static website:
div id=form/div
script
type=text/javascript$(#form).load(path/to/web2py/app);/script
And this in the web2py app:
def email():
script =
$(#contact_form).submit(function(event) {
$.post(this.action, $(this).serialize(), function(response) {
$(#contact_form).replaceWith(response);
});
return false;
});
form = FORM(
SCRIPT(script),
TABLE(
TR('Message:', TEXTAREA(_name='message',
requires=IS_NOT_EMPTY())),
TR('', INPUT(_type='submit')),
),
_action=URL(),
_id='contact_form'
)
if form.accepts(request):
# process result ...
return 'Message received'
else:
return form.xml()
The key part is: $(#contact_form).replaceWith(response);
Each AJAX request the form is replaced with the latest response, which is
either a form with errors or the success message.
This works as expected, but is there a better way to do this?

Hi All,
I am using the below statement to serialize images in my view
-
{{=TAG.img(_width=25, _height=30, _src=URL(r=request, c='default',
f='download', args=[adminupdate.profile_pic]))}}
What could I do to make the browser keep the images in cache?

[web2py] redirect doesn't redirect.
I am working on a network app, in which I use the same controllers and
views for all hubs. To keep them separated all hubs have an id and
every hub function start with test_hub_vars:
def test_hub_vars():
if not len(request.args):
redirect(URL('default','error'))
elif request.args(0)==1:
redirect(URL('default','index'))
else:
if not (session.hubnetworkID and session.hubword and
session.hubcontroller_menu):
init_hubvars(request.args(0))
elif session.hubnetworkID != request.args(0):
init_hubvars(request.args(0))
def init_hubvars(networkID):
session.hubnetworkID=networkID
row=db(db.NetworkKeyword.networkID==request.args(0)).select(db.NetworkKeyword.word).first()
if row:
session.hubkeyword=row.word
else:
redirect(URL('default','error'))
session.hub_header_top=URL('static','init/images/hub/
hub_header_top.jpg')
This almost works. The exception is the redirect to the default index
function in this case:
http://127.0.0.1:8000/init/hubaddressbook/index/1
the test_hub_vars function should redirect to
http://127.0.0.1:8000/init/default/index
which it doesn't do. I cannot figure out why this doesn't work.
Kind regards,

Thanks, i will test by the end of the week.

I have created another plugin for the MarkItUp widget. I know that
plugin_wiki has this currently, but I wanted a dedicated plugin for this
for an upcoming project I'm working on.
You can get the plugin from Bitbucket:
https://bitbucket.org/PhreeStyle/web2py_markitup
There is no documentation yet, as I just pushed the code. But I wanted to
announce in case anyone wants to play with this. It has not been thoroughly
tested and is only an alpha at this point. It can be used with several
different markup languages:
- BBCode
- HTML
- Markdown
- Markmin
- reStructuredText
- Textile
- Wiki
The plugin can be used standalone, or as a form field widget. It currently
supports live previews for 4 markup languages: html, markmin, markdown,
textile, and bbcode. Code blocks for markmin and markdown markup are
highlighted by pygments, which is included as part of the plugin. No
external dependencies. Using pygments for code highlighting allows over 100
languages to be highlighted.
Code highlighting in markmin:
``
def testing():
print 'Testing'
``:python
Code highlighting in markdown:
:::python
def testing():
print 'Testing'
Markdown requires four spaces at the beginning of each line for code
blocks.
Example for basic usage:
from plugin_markitup.markitup import MarkItUp
def test():
widget = MarkItUp(set_name='markmin').markitup()
return dict(widget=widget)
Example model for form fields:
from plugin_markitup.markitup import MarkItUp
db.define_table('content',
Field('name', length=20),
Field('description', 'text')
)
db.content.description.widget = MarkItUp().widget
Example controller:
def test():
form = SQLFORM(db.content)
if form.accepts(request, session):
redirect(URL())
return dict(form=form)
This plugin is more of an alpha preview, so I expect there to be problems
and inconsistencies. Please try it out and let me know if you have any
questions, comments, or problems!
[web2py] Re: One time action for user
This isn't foolproof, but upon voting, you can send a cookie to the user's browser. Before allowing a user to vote, check for the cookie, and if it exists, don't allow the vote. Note, this will only prevent someone from voting twice from the same machine and browser, assuming they don't delete the cookie. If someone attempts to vote multiple times, you might not want to notify them that the subsequent votes don't count -- in that case, they may catch on and figure out how to vote multiple times by deleting the cookie or switching browsers. See http://web2py.com/books/default/chapter/29/4#Cookies.

Re: [web2py] Problem with update
You should replace IS_NULL_OR by IS_EMPTY_OR, IS_NULL_OR is depricated if I
remember.
I don't see what could be wrong... But I read recently about test that
could be conflicting with web2py some how...
But I guest that you try to implement a home made solution to follow logged
on and logged off user... I think you should have a look to comet server a
contrib to web2py that is supposed to allow tracking connection to app.

I think list comprehensins are reasonable way to populate drop-downs. You don't need to specify he select fields if you dont want to. Then you'll just gt back ALL fields. Naming the db db is much easier to read for us.

that caches something into web2py, not into browser. To cache into browser, probably the most rapid way is to send out expire headers in the future. something like this would cache the file into browser for 30 days You are using the default download function, so if you need this functionality you must add these lines to that function def download(): allows downloading of uploaded files http:///[app]/default/download/[filename] import datetime response.headers['Cache-Control'] = 'public' response.headers['Expires'] = datetime.datetime.strftime(request.utcnow + datetime.timedelta(days=30), '%a, %d %b %Y %H:%M:%S GMT') return response.download(request,db)
[web2py] Current status of adapting OrientDB for web2py
I'm researching the nosql and graph database landscape for a web2py application that will require the schema to evolve over time and provide network/graph analysis metrics. I started by looking at the Tinkerpop (http://tinkerpop.com/) stack and the Bulbflow (http://bulbflow.com/) python library for interacting with Tinkerpop graph databases like Neo4j and OrientDB. It looks like there was interest a few months back in adapting OrientDB's sql interface for web2py, and there is an open issue: - http://code.google.com/p/web2py/issues/detail?id=407 A few questions: What is the current status of an OrientDB/web2py adapter?

[web2py] Re: Dedicated IDE
Happily using Komodo Edit 6. If web2py is in the pythonpath, you get autocomplete for it as well as the rest of python. I find it handier than using any of the dedicated python ide's because you also must work on html views and css files. It has autocomplete, syntax checking, and brace matching for all 3 languages (and many more). It has built-in sftp support so editing web2py files on my site is almost local. I haven't figured out projects yet. I haven't seen the need for Komodo IDE, which must do a lot of additional magic for its price ($299 I think ??).

Re: [web2py] Re: [w2py-dev] Re: Movuca - Social CMS beta 0.1
LGPL is designed for libraries. Static or dynamic linking to LGPL code is allowed without enforcing copy-left. That means that the derivative work can even be a proprietary software. However, if you change the library code itself, you modification has to be released under LGPL. Since version 3 LGPL is compatible with GPL, which means that the modifications could be released under GPLv3 too. In case of CMS, all these doesn't matter in practice. CMS is not a self-contained isolated library and except of very simple projects, a web application build on top of it will require changes in the CMS code. So commonly, there would be the same copy-left enforcement in place as in case of the GPL. There is also no difference between GPL and LGPL with respect to the server deployment. Both licenses do not see that as distribution, so the deployed code, whatever type of changes it contains, can remain secret. That's why my recommendation was GPLv3, as in this case there is no way to get anything extra from LGPL anyway. I guess the key difference is in the licenses compatibility. Under LGPLv3 you can include all non copy-left free software (BSD, MIT, MPL 2.0, Apache 2.0) but not the code under the GPL (you would have to release the combination under GPLv3, for details see the compatibility matrix [1]). With GPLv3 it's simpler as more licenses are compatible (see the full list [2]), including GPLv2 as long as the phrase either version 2 of the License, or (at your option) any later version is present in the copyright notice. For more arguments in the GPL vs LGPL case see [3].

[web2py] How to keep plugins up-to-date across apps
I'm using a lot of custom plugins to allow re-use of code across several of my web2py apps. But since the plugins are in a state of constant updating, it's getting to be a pain to keep them all in sync. I use git for version control (one repo for each app) and for deployment (on Fluxflex). I've considered trying to use git submodules, but have found them a bit confusing (in the little time I've spent looking at them). The overall problem seems to be exacerbated by the fact that a plugin's files are spread out across the app's file structure. Any suggestions? Thanks, Ian
Re: [web2py] How to keep plugins up-to-date across apps
I never try it... But since web2py like linux and unix everything is in a file somewhere, you maybe could try to make use of symbolic links... So you could have a app (plugin app) that is linked as a plugin in others app (main app that rely on some plugins). Really not sure how well it could work. If you try something, I would be interested if you report the problems you face and how you walk around.

Thanks to everyone for answering my questions so far. At the deployment section of the book now. Earlier I've been running web2py with python 2.7 but to run from source I need to install 2.5. The python web site has an msi installer for 2.5 but only source code for 2.5.6. http://www.python.org/getit/releases/2.5.6/NEWS.txt describing the differences. the text file is a bit too long to paste here.

[web2py] CSV Import performance improvement idea
I have a problem with the performance of CSV import and I assume it generate INSERT statement for every record so it will be 8000 statement if you have 8000 records in csv file. Can we use bulk_insert method instead so there will be always only one INSERT statement which should reduce the performance significantly ?

At the deployment section of the book now. Earlier I've been running web2py with python 2.7 but to run from source I need to install 2.5. Actually, if you've been running web2py with Python 2.7, then you have been running the source version of web2py. The version of web2py that comes with its own Python 2.5 interpreter is the binary version (for Windows or Mac), not the source version. The python web site has an msi installer for 2.5 but only source code for 2.5.6. http://www.python.org/getit/releases/2.5.6/NEWS.txt describing the differences. the text file is a bit too long to paste here. If you want to run from source, then you do not need Python 2.5 at all -- Python 2.7 is fine. If you want to run the binary version of web2py, you don't have to install Python (in fact, even if you do install your own Python, it will be ignored and web2py will use its own Python 2.5 interpreter).

[web2py] Re: how to pass db object to component?
Is this an ajax component? In that case, all the LOAD helper is doing is
setting up the JS code to make an ajax GET request to the component's URL,
so you can't easily pass large amounts of data to the component function.
If you only need the results of the query within the component, you might
be better off doing the query in the component function (i.e., f1() in your
example). Otherwise, maybe cache the results of the query and have the
component function pull it out of the cache (or put it in the session if
the results are unique per user).

In other words:

{{=LOAD('c1','f1')}}
So where in the LOAD statement can I pass in data as a db Storage or

[web2py] Join operations on google app engine
I have an online application deployed on google cloud. I have used web2py framework to develop the application. I have 2 tables the auth_user table and tasks table.Both of them have more than 1000 records each.The tasks table contains person_id field which stores the id's in auth_user table I need to fetch the data from 2 tables and display it. Since I am having large data it results in request time out(Deadline Exceeded Error). When I fetch from a single table it works fine. Since Google App Engine does not support JOIN operations I was fetching the entire data from both tables and then peforming operations, it would result to request time out. So I thought of adding the necessary fields that are in auth_user to tasks table but since there are more than 1000 records updating each record manually is cumbersome. Does web2py provide any bultin methods(like database validations) to update the fields based on person_id present or I should update it manually?

About fnInitComplete it is just needed in case you want to initialise

[web2py] Re: dataTables with serverside json
Yes.
As a side note, DABO is written fully in Python itself.
It is a full fledged framework using wxPython for GUI.
But I am using its database-interaction tier business-logic tier
(dabo.biz dabo.db).
Since we, web2py followers, are using web2py as a footing, you may
ignore the code regarding ui in the below-referred links.

Hi Vineet,
Thanks for sharing. So, if I understand correctly, you use DABO code as an
equivalent of the php code in the example from the DTs to allow grid to
interact with database...
I will have a look at PowerTable this week to see if it actually implement
server processing and if not to try to figure out how we could add the
feature...

[web2py] * DATE FIELDS REPRESENT *
Hi there!
Please help me deal with date representation.
For example, I have a date field:
Field('date_start', 'date', default = datetime.date.today())
db.contracts.date_start.represent = lambda v:v.strftime('%d.%m.
%Y')
It works perfectly if I use SQLFORM.
But if I use just selection from db and do something like this in a
view:
{{for row in contracts:}}
td{{=row.date_start}}/td
{{pass}}
it turns to the defaul value representation: %Y-%m-%d.
So in this case I should use strftime for correct all date values:
{{=row.date_start.strftime(%d.%m.%Y)}}
But maybe there is a better way to go!?!
And another question about datetime picker in forms.
By default input value looks like that 2012-02-14.
I need to change it to 14.02.2012.
How can I change it? Where should I look for?
I'll appreciate for any help. Thanks!
[web2py] Re: Multiple different problems - Dealing with Integrity Error for nutnull=True and unique=True database fields
All,
Pondering over with Anthony's solution, I just uploaded images to
static folder and that works wonders for image caching.
Below is the code that I changed in db.py for my model -
Field('profile_pic', 'upload', uploadfolder=request.folder
+'static/user_pics', requires=IS_LENGTH(262144)),
Just a minor hiccup that it sometimes or initially loads the images
partially (esp png files, not tried with gif's) . Still, I am happy
with the way images are being rendered now. I will still consider the
below solution from Anthony for more further analysis..
Thanks for getting back so quickly .. .web2py community is superb!

[web2py] request.args returns each arg as string
I posted a question asking why this doesn't work: if request.args(0)==1 the answer: request.args returns each arg as string However, in my application I use this multiple times: rows=db(db.node.id==request.args(0)).select(db.node.ALL) where id is of type integer and not string. What is the difference between the first use request.args(0) and the second use? Kind regards, Annet.

Re: [web2py] request.args returns each arg as string
in the second example the DAL query operator == is taking care of trying to convert your data to the right type. http://zerp.ly/rochacbruno Em 14/02/2012 05:14, Annet anneve...@googlemail.com escreveu: I posted a question asking why this doesn't work: if request.args(0)==1 the answer: request.args returns each arg as string However, in my application I use this multiple times: rows=db(db.node.id==request.args(0)).select(db.node.ALL) where id is of type integer and not string.

Can we use bulk_insert method instead so there will be always only one INSERT statement which should reduce the performance significantly ? As I understand it the database (at least Postgresql) uses the COPY statement to import csv-files. That is much quicker than a series of individual inserts.
