[web2py] how to restart we2py running as fastcgi process under Apache?
I just launched an app into production that uses the Python Imaging Library
(PIL). PIL was installed on my local development environment, but not on
my production server, and the app started throwing errors.
I installed PIL on the server. If I launch the app in web2py's interactive
command line shell in a console on the server, I can import it without
error, so I know it's installed and web2py can pick it up. But the app is
still throwing errors when viewed in a browser.
I'm assuming that's because the server needs to be restarted. I'm running
it as a fastcgi process under Apache. I respond to each request using this
file I call web2py.fcgi:
#!/home/myaccount/.env/bin/python2.7
# python running in virtual environment named '.env'
import sys, os
# add web2py to the front of the system's executable path
sys.path.insert(0, "/home/myaccount/web2py")
# this assumes flup is already installed on the server
from flup.server.fcgi_fork import WSGIServer
# Switch to the web2py directory so gluon can be imported
os.chdir("/home/myaccount/web2py")
# import the web2py's fcgi gateway
import gluon.main
import gluon.contrib.gateways.fcgi as fcgi
application=gluon.main.wsgibase
# or
# application=gluon.main.wsgibase_with_logging
WSGIServer(application).run()
I have attempted to restart using:
sudo pkill web2py.fcgi
sudo service apache2 restart
That seems to clear out the web2py.fcgi processes and restarting the
server, but, I'm still getting 'No module named PIL' errors.
Any suggestions you could provide would be greatly appreciated!

[web2py] Re: Upgrading from 2.08 to 2.18.5
OK, I installed the current version of web2py on my laptop and copied over
the 'init' application and a 'blog' application. I've launched the test
server and opened the blog app in my browser.
The main problem I'm having now is URL rewriting. Here's routes.py in my
blog app:
default_controller = 'default' # ordinarily set in app-specific routes.py
default_function = 'index' # ordinarily set in app-specific routes.py
#
routes_in = (
('/blog/category/$anything', '/blog/default/tag/$anything'),
('/blog/static/$anything', '/blog/static/$anything'),
('/blog', '/blog/default/index'),
('/blog/$anything', '/blog/default/post/$anything'),
)
routes_out = [(y,x) for (x,y) in routes_in]
And here's the index template of the blog:
{{ response.files.append(URL('static/css/blog.css')) }}
{{extend '../../init/views/layout.html'}}
Latest Blog Posts:
{{ for post in posts: }}
{{ =post.title
}}
{{ if post.thumbnail: }}
{{ pass }}
{{ =post.meta_description }}
More
{{ pass }}
On the old version of my blog, I would get relative URLs
'/blog/', but now I'm getting '/blog/default/'.
SImilar behavior is occurring in the top-level navigation. Has routing
behavior changed?

[web2py] web2py and python3
I know this has come up in the past, but it hasn't been asked in a while. Is there ever going to be a usable and maintained Python3-compatible fork of web2py? The latest edition of Fedora now ships with Python3 by default. It's the default version used in Django's tutorial. I'm not using Python3 now, but I can see the day when I inevitably will.

Re: [web2py] Re: Load content from a text file
I'm not an expert in web2py, but this one approach I think should work
for your application. If others have better ways of doing it, please
share them:
def readfile():
'''
returns the file to be read
'''
response.view = '/path/to/file_to_be_read.txt'
return locals()
def writefile():
'''
writes the values of the form in basic, unescaped CSV format
'''
form = SQLFORM.factory(
Field('name'),
Field('choice', requires=IS_IN_SET(['1','2','3'], zero=None)),
)
if form.validate():
fh = open('path/to/file_to_write_to.txt', 'w')
fh.write(','.join(form.vars.values()))
fh.close()
response.flash = 'Your data has been submitted'
return dict(form=form)
It sounds like in your application, you are reading the serial port at
fixed periodic intervals and writing the data to a file. If you only
need to read or write to it when a user requests a page, this is what I
was suggesting instead:
def readdata():
'''
read data from serial port and return it in a view
see the Python PySerial module documentation for details
'''
import serial
try:
ser = serial.Serial('/dev/ttyS1', 19200, timeout=1)
data = ser.readline() # read a '\n' terminated line
ser.close()
except:
data = 'cannot read serial port'
return dict(data=data)
writing to the serial port would be just as easy:
def writedata():
'''
writes form values in basic, unescaped CSV to the serial port
'''
import serial
form = SQLFORM.factory(
Field('name'),
Field('choice', requires=IS_IN_SET(['1','2','3'], zero=None)),
)
if form.validate():
try:
ser = serial.Serial('/dev/ttyS1', 19200, timeout=1)
ser.write(','.join(form.vars.values()))
ser.close()
response.flash = 'Your data has been written'
except:
response.flash = 'Cannot write to serial port'
return dict(form=form)

Jim, not quite sure how to do what you suggest. The serial
communication is using an special protocol that the app reads and
creates an text file from.
The app stores also everything in the database but I thought it
would be more efficient for this page to get the info from an text
file. There will be many other pages that will be using mobile
jquery with an normal menu that reads data from the database, but
this one special page will be just a blank page showing the content
of the file if I can't find out how to reload just the part of the
page that shows the text file. Was thinking using PHP to show that
page.
Kenneth
Now many clients need to access this at one time? The issue is the
workload on the pi.

[web2py] Re: Load content from a text file
Do you need to use a text file as an intermediary? I created a similar app for my pedal-powered laptop (described at www.pedalpc.com) where a function is called in the controller that reads/writes the serial port and returns the data as JSON which just updates the necessary data in the page in the browser. This method assumes the client has the processing power to handle updating the page via JSON...

[web2py] Re: DAL does not return correct id when inserting a record where the id is specified
Thanks for your answer, Anthony. Its not necessary to change the code for
this since the id is already known if its being inserted anyway :) . I
just didn't expect that behavior.
On Tuesday, August 6, 2013 11:34:07 PM UTC-5, Anthony wrote:
The DAL does this to get the id for MySQL inserts:
self.execute('select last_insert_id();')
Unfortunately, the value of last_insert_id() is only updated when the id
is auto-generated, so it stores the last auto-generated id (which you
observed), not the last id.
In order to get the last id (whether auto-generated or not), you need to
use the MySQL
mysql_insert_id()http://dev.mysql.com/doc/refman/5.0/en/mysql-insert-id.htmlC
API function. I'm not sure if this is available via the pymysql driver,
but the MySQLdb driver connection object does include a conn.insert_id()
method to access this function (see
http://mysql-python.sourceforge.net/MySQLdb.html#mysql-c-api-function-mapping).
Perhaps the DAL code can be changed to use that method when the MySQLdb
driver is being used. If you'd like, you can open a Google Code
issuehttps://code.google.com/p/web2py/issues/listabout this (and reference
this thread).

[web2py] DAL does not return correct id when inserting a record where the id is specified
I noticed an odd behavior when inserting a record in a MySQL table. Given
a table:
db.define_table('person', Field('name'))
inserting some records without specifying the id returns the correct id:
db.person.insert(name='John')
1
db.person.insert(name='Bill')
2
But specifying the id when the record is inserted does not:
db.person.insert(id=3, name='Fred')
2
db.person.insert(id=10, name='George')
2
even though the records are inserted correctly:
print db().select(db.person.ALL)
1 John
2 Bill
3 Fred
10 George
Is this unique to MySQL? Is this a bug or is there a logical reason for
this?

Don't know if this applies in your situation, but one problem I've encountered is I always assumed that simply adding a response.files. append (page.css) to the top of a view before extending the default layout.html template would put the page.css file last in the hierarchy. If you look at the code, it doesn't. It puts it first. In fact, I have yet to find a method of appending a custom css file to the hierarchy without changing the layout template explicitly to change the default loading order.

[web2py] how to validate forms using extra data?
I have a form with five text input boxes:
form = FORM(*[INPUT('amount-%s' % i, _type='number') for i in range(5)],
INPUT(_type='submit'))
The sum of these input boxes must equal the value of a field in a database
record.
I would like to pass the database record as a parameter to the onvalidation
callback of the form, but as I understand it, this is not possible--the
onvalidation function can only be passed one argument, the function itself.
So, instead, I have written a second function to check validation after the
form passes its initial validation:
def _validate_form(form, record):
total = 0.0
for f in request.vars:
if request.vars[f].startswith('amount-') and request.vars[f] != '':
total += float(request.vars[f])
if total != record.total:
for f in request.vars:
if request.vars[f].startswith('amount-') and request.vars[f] != '':
form.errors[f] = 'total of amounts must equal record total'
return form.errors
def test():
record = db.table[request.args(0)]
form = FORM(*[INPUT('amount-%s' % i, _type='number') for i in
range(5)],INPUT(_type='submit'))
if form.validate():
form.errors = _validate_form(form, record)
if not form.errors:
redirect('next_page')
return form
The trouble I am having is the test--'form.errors' returns True (and hence
'not form.errors' returns False) even when _validate_form returns an empty
form.errors Storage object.
I don't understand why it does. How should I test for this condition
instead?
Is there another way I could do this using the onvalidation function, other
than passing the record id as a hidden form field and doing the record
selection in the validation function? (In my actual application, the
record must be selected before the form is created.)

You're right, either method would work. But is it possible without having
to look up the record twice (once when creating the form, the other to
validate it)?
Another option would be to pass the amount (record.total) as a hidden field
rather than retrieve it using the record_id

[web2py] Re: getting the name/value of a submit button
Thanks for that useful information, Anthony. I ended up creating a hidden variable in the form and setting the value of the variable when the button is clicked, i.e., FORM( INPUT(_type='submit', _value='button1', _onclick='document.form1.hiddenvar='button1';), INPUT(_type='submit', _value='button2', _onclick='document.form1.hiddenvar='button2';), _name='form1', hidden=dict(hiddenvar='') ) That works OK, but I'm not sure how you could generalize it for any web2py.js form submission :). On Monday, July 1, 2013 9:58:56 AM UTC-5, Anthony wrote: Ajax form submissions use the jQuery .serialize() method, triggered by the form submit event. The .serialize() method doesn't know how the form was submitted, so it does not have information about any button clicks (and therefore the name of the button that was clicked). You can search online for some workarounds to this problem. If you come up with something generalizable, maybe we can add it to web2py.js.

[web2py] Possible to turn off server logging in local environment?
I run web2py in the background on my PC to monitor my power output when I'm working on my pedal-powered computer. (see http://www.bikesatwork.com/blog/our-pedal-powered-office) The script I'm running does sends a JSON request to my local server every second, which means the log file grows quickly over time. Is there any way to turn off server logging to prevent this? Or should I just schedule a task to delete the file every day or so? If I rewrote this app as a web socket, would it still log every second? Thanks, -Jim -- --- You received this message because you are subscribed to the Google Groups web2py-users group.

Sounds like your CSS file is missing. View the source of the page and see if it is referencing the CSS file. If so, try accessing the CSS file directly by copying and pasting the URL of the file from the page source into the location bar of your web browser. If you get a 404 error, then either the fille is missing or you're referencing the wrong URL in your layout.html template. -- --- You received this message because you are subscribed to the Google Groups web2py-users group.

I am storing the files in the uploads folder. I've tried creating an index based on the filename and it doesn't appear to markedly improve the situation. Upon further investigation, it seems to be more a problem with our server--or just internet routing--than anything else.

These attributes have to be callables, so you can't call them yourself. To
pass additional custom arguments to a callable, just turn it into a lambda
that takes the standard arguments and pass the additional arguments to your
function within the lambda:
Field('file', 'upload',
custom_store=lambda file, filename, path: store_file(file, filename,path
, db.table.new_filename),
...)
When web2py calls the custom_store callable, it will pass three arguments
(file, filename, and path), so your lambda must take three arguments.
Within the lambda, you can then do whatever you want. You can pass any or
all of the standard three arguments to your custom function, and you can
pass additional arguments. In the example above, I passed the three
standard arguments followed by a fourth custom argument, though it doesn't
have to look like that (presumably you will at least want to pass the file
as an argument).
custom_retrieve takes two standard arguments, name and path.

[web2py] how to remove duplicate tables in smartgrid?

Field('description', 'text'),

db.define_table('related_product',

)
If I create a smartgrid on the 'product' table using:
def product():
return dict(grid=SQLFORM.smartgrid(
db.product,
linked_tables=['related_product'],
))
the related_product table appears twice because it references the
product table twice. Any way to prevent this?
