Hi,

http://web2py.com/books/default/chapter/29/13/deployment-recipes

this page offers different deployment  recipes for hosting like
PythonAnywhere. If your host (i am unfamiliar with go-daddy) provides you
root/shell access to a linux box, you shouldn't have any trouble. I am
Running my web2py instance from a VPS service.

you can do it from the shell. Look up your relevant distro information
on init scripts.

usually it's something like

sudo service apache2 restart

Re: [web2py] Using "Homemade task queues"

[Calvin Morrison]

Look at the scheduler documentation. I have mine called this way from
my db.py. This calls a few different tasks, adding file size and also
calling a task called unzip / untar which are functions i have written
to handle zipping and unzipping. Hopefully this explains it somewhat


def upload_post_hook(row_id):

row = db(db.uploads.id == row_id).select('up_file', 'username',
'filename')[0]

add_size(row_id)

if row.filename.endswith('.zip'):
scheduler.queue_task(unzip,pvars=dict(filename=row.up_file,
username=row.username, folder=request.folder,
real_filename=row.filename, id=row_id))
if any(row.filename.endswith(ext) for ext in ['.tar', 'tgz',
'.tar.gz', '.tar.bz', '.tar.xz', '.tar.bz2']):
  scheduler.queue_task(untar,pvars=dict(filename=row.up_file,
username=row.username, folder=request.folder,
real_filename=row.filename, id=row_id))

return None


db.uploads._after_insert.append(lambda id, i: upload_post_hook(i))

[web2py] Slow response

[Calvin Morrison]

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?

that'd be a Jquery thing.

Yes I am getting that same problem here.

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

Re: [web2py] Multiple Uploads using jQuery-File-Upload: Javascript/CSS Conflict?

[Calvin Morrison]

:-) 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?

Calvin

Re: [web2py] Multiple Uploads using jQuery-File-Upload: Javascript/CSS Conflict?

[Calvin Morrison]

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())
  db.commit()

redirect(URL('data', 'index'))
  else:
form.errors.up_files = "No files selected"

  return dict(form=form)

[web2py] require based on another field.

[Calvin Morrison]

Hi!

I have a field called "Job Type", and another field "database" that
depends on the type. If the user selects "Train" for Job Type, they
don't need to enter a database (a integer id), but i don't know how to
make validators do this for me.

Right now I have this:

db.jobs.db.requires =
IS_NULL_OR(IS_IN_DB(db((db.quikr_database.username == auth.user.email)
| (db.quikr_database.share_with_others == True)),
db.quikr_database.id, '%(name)s'))

Either it can be null (in the case of Train) or otherwise it needs to
be in the list of shared quikr_databases.

Any ideas?

Re: [web2py] Re: save upload filename in database

[Calvin Morrison]

Here is my solution!


  if hasattr(request.vars['up_file'],"filename"):
form.vars.filename = request.vars['up_file'].filename

  if form.process().accepted:
redirect(URL('data', 'index'))
  elif form.errors:
response.flash = "form has errors"

More specifically this only happens if I put in the if up_name != None 
check to set the filename in the database, otherwise it works well

[web2py] save upload filename in database

[Calvin Morrison]

I'm following the documentation trying to figure out how to correctly save 
a filename to my uploads database.

Basically i have the same code as the website shows in it's examples


def submit():


 import datetime


 form = SQLFORM(db.uploads, fields=['up_file', notes], deletable=True)


 form.vars.up_date = datetime.datetime.now()
 form.vars.username = auth.user.email


 if request.vars.up_file != None:
 form.vars.filename = request.vars.up_file.filename


 if form.process().accepted:
 redirect(URL('data', 'index'))
 elif form.errors:
 response.flash = "form has errors"


But my form doesn't appear to be validating correctly. It allows me to hit 
submit even if a file is not supplied. This leads to a error being logged, 
so I want to avoid things getting submitted.  My only thought is that it 
could be my requires not working correctly

ext_regex = '|'.join(quikr_utils.all_ext)

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
(), IS_UPLOAD_FILENAME(extension=ext_regex)]),
Field('up_date', 'datetime'), 
Field('up_size', 'integer', represent= lambda x, row: quikr_utils.
sizeof_fmt(x) ), 
Field('notes', 'text'))

>>> print quikr_utils.all_ext
['fasta','fa','fna','fasta.gz','fa.gz','fna.gz']

Any ideas?
Thanks!
