PIL: IOError: encoder jpeg not available June 2, 2009
I have got this error while doing this
import tempfile
bg_new=Image.new(‘RGB’,(486,236), GREEN)
tmp = tempfile.mktemp(suffix=’.%s’ % ‘jpg’)
bg_new.save(tmp, “JPEG”, quality=95)
I was looking for solution and got this:
in setup.py in Imaging-1.1.6 that is PIL 1.1.6
set this
JPEG_ROOT = “/usr/lib64″, “/usr/include”
then in terminal
python setup.py build –force
this will include libjpeg in PIL. before you may need to install libjpeg in your linux system. I have tried this with python2.4 in ubuntu 8.10
hope this works
how to add external method while installing product in plone May 6, 2009
in profiles/default create import_steps.xml
Import easysearch settings
in the product create setuphandlers.py file like this
# created by tareq alam
# tareq.mist@gmail.com
# www.commitmentsoft.com
from Products.CMFCore.utils import getToolByName
from Products.CMFPlone.utils import safe_hasattr
from Products.Archetypes.public import listTypes
def importVarious(context):
"""
Final easysearch import steps.
"""
site = context.getSite()
invokeFactory = getToolByName(site, 'invokeFactory')
manage_delObjects = getToolByName(site, 'manage_delObjects')
#getattr = getToolByName(site, 'getattr')
try:
manage_delObjects("reportExternalMethods")
except:
pass
Newfolder = invokeFactory("Folder", id="reportExternalMethods", title="reportExternalMethods",path='/')
Newfolderobj = getattr(site, Newfolder, None)
manage_addProduct = getToolByName(Newfolderobj, 'manage_addProduct')
em = manage_addProduct['ExternalMethod']
manage_addExternalMethod = getToolByName(em, 'manage_addExternalMethod')
manage_addExternalMethod('imageexample', 'imageexample', 'easysearch.imageexample', 'imageexample')
manage_addExternalMethod('createResultPy', 'createResultPy', 'easysearch.createResultPy', 'createResultPy')
#em = context.manage_addProduct['ExternalMethod']
now restart and install product
this will create a folder reportExternalMethods in root .. and also create two external methods in that folder

add contents and publish in plone using python script March 30, 2009
add a external method
in the method’s python file
Newfolder = context.invokeFactory(“Folder”, id=”NEWFOLDERINPLONE”, title=”NEWFOLDERINPLONE”,path=’/’.join(context.getPhysicalPath()))
this will add a new folder in the contexts directory
To publish this folder automatically by code try this magic
Newfolderobj = getattr(context, Newfolder, None)
review_state = Newfolderobj.portal_workflow.getInfoFor(Newfolderobj, ‘review_state’, ”)
if not review_state == ‘published’:
Newfolderobj.portal_workflow.doActionFor(Newfolderobj,”publish”,comment=”publised programmatically”)
it will be published in site on the fly…
to add page template
idict = { ‘id’ : ’step1Page’
, ‘type’: ‘page template’
, ‘body’: page_template_body # variable can be a content of a pt file
, ‘workflow_action’: ‘publish’
, ‘workflow_comment’: ‘This item published programmatically’
}
Newfolderobj.manage_addProduct['PageTemplates'].manage_addPageTemplate(id=idict['id'])
oi = getattr(Newfolderobj,idict['id'])
oi.pt_edit(idict['body'],’text/html’)
this will add a page template in new folder
together
def main(self):
# Example code:
# Import a standard function, and get the HTML request and response objects.
from Products.PythonScripts.standard import html_quote
context = self
try:
Newfolder = context.invokeFactory("Folder", id="NewFolderUnusedId", title="NewFolderUnusedId",path='/'.join(context.getPhysicalPath()))
except:
Newfolder = 'NewFolderUnusedId'
Newfolderobj = getattr(context, Newfolder, None)
review_state = Newfolderobj.portal_workflow.getInfoFor(Newfolderobj, 'review_state', '')
if not review_state == 'published':
Newfolderobj.portal_workflow.doActionFor(Newfolderobj,"publish",comment="publised programmatically")
f=open("somefile.pt","r")
page_template_body = f.read()
f.close()
idict = { 'id' : 'step1Page'
, 'type': 'page template'
, 'body': page_template_body
, 'workflow_action': 'publish'
, 'workflow_comment': 'This item published programmatically'
}
Newfolderobj.manage_addProduct['PageTemplates'].manage_addPageTemplate(id=idict['id'])
oi = getattr(Newfolderobj,idict['id'])
oi.pt_edit(idict['body'],'text/html')
return true
Add new widget in PloneFormGen March 30, 2009
PloneFormGen is a nice tool to add dynamic forms in plone
There are lot of different form fields in PloneFormGen
but I was in need of a new type of widget in my form
this is how i did that
first to learn how it works..
http://plone.org/products/pfgdatagrid
download this product and install it after installing DataGridWidget and PloneFormGen
now you can add datagrid widget directly in plone form folder
to use a new type of widget as like data grid widget you can do the following steps
1. copy the PFGDataGrid and paste with name as you like for example PFGNoneMultiSelectionWidget
2. inside the folder change in the following files
content
__init__.py will contain import nonemultiselectionff
rename the datagridff.py to nonemultiselectionff.py
in every file in every folder
also in nonemultiselectionff.py you have to define the schema and the function
for this you need to study and this is different for different widgets
you have to define functions so that you can take the widget from the products folder
follow example in datagridfield and in ploneFormGen fields.py for ideas
or call me 
change PFGDataGrid to PFGNoneMultiSelectionWidget
and change FormDataGridField to FormNoneMultiSelectionWidget
XLS: DATE() function to convert integer to date and get date difference December 11, 2008
Problem: I have two cell with integer value like this in A1: 20080101 and n C1: 20080116. These are dates but in integer field. I need to put the difference of date between C1 and A1 in B1
Solution: click on B1 in the function bar type this:

Internet explorer loads same image more than once with ajax December 5, 2008
In Internet Explorer when an html is loaded with image inside if the image is same in all img tag internet explorer loads the image each time it foinds in img tag.. this makes the ajax loading slower. AJAX is used to make a web page faster but IE seems having problem with that.
To solve this i have applied an idea .. searching google i came to know that IE loads single time of same image located in style background of an element. so I made img tag to div with style background property to the src of the image … now if i load 100 of that div via ajax it loads only one time. Thus my web page loads faster in IE.. Thanks to FireFox it behaves nice with this problem.
Hope this helps
