Using Reportlab inside Zope (Python Scripts)

Created by . Last modified on 2003/08/05.

Reportlab (www.reportlab.com) is a tool for generating dynamic PDF documents.

There is a sample using a External Method in
ReportLab distribution.

Here, you will find how to use reportlab using
python scripts inside zope.

Steps:

I - Installing ReportLab and Pithon Imaging Lybrary
---------------------------------------------------

1.Download Reportlab (http://www.reportlab.com/download.html)
-- Reportlab Toolkit
-- http://www.reportlab.com/ftp/ReportLab_1_17.zip

-- Reportlab dlls for Python 2.1 (Zope 2.6.1)
-- http://www.reportlab.com/cgi-bin/zipper.sh?win32-dlls/2.1+rl_win32_2_1.zip

2. Download Pithon Imaging Library (PIL) for python 2.1 (Zope 2.6.1)
-- http://www.pythonware.com/downloads/py21-pil-1.1.2-20010910.exe

3. Install reportlab
3.1. Under Zope_Directory/bin/DLLs
- all dll files
3.2. Under Zope_Directory/lib/python
- folder: reportlab

4. Install PIL (note case)
4.1. Under Zope_Directory/bin/DLLs
files: _imaging.pyd and _imagingtk.pyd
4.2. Under Zope_Directory/lib/python
folder: PIL

7. Create a folder under Zope_Directory/lib/python/Products named "GlobalModules"
7.1. Create a file __init__.py
7.2. For each module and class that you need,
you must add "allow_modules" and "allow_classes",
as you see below:

File __init__.py
