4. Plone = Python based CMS
CMS = Contents in Database
Added/Edited by User/Group
Managed via Workflow
Searchable with Index/Catalog
or simply…
Forms in Database

5. Installation Options
1. Unified Installer
2. /usr/bin/python
3. VirtualEnv

8. Undo, Transaction, Versioning
How Plone Database Interacts with Applications
Python’s dynamic nature allows
developers to quickly develop applications,
avoiding the compile cycle and static
typing declarations required by other
languages. The ZODB offers a similar
benefit: developers who use the ZODB can
store their objects transparently without
any cumbersome mapping of objets to
relational database tables.

With a Little Help from My Friends

18. Python Building Blocks
Python Packages are distributed as Eggs
Python Package Index
http://pypi.python.org/
Example:
easy_install docutils
pip docutils

19. How Plone Add-ons Work
zc.buildout helps to install addons

20. Extend Plone with Add-ons
Plone Addon (Product) =~ Python Package (Egg)

21. Forms are Common in CMS
Form = Content Type

22. Form = CMS Core
Content Type = Schema
= Fields + Widgets

23. ArcheTypes Content Framework
ATNewsItemSchema =
ATCTSchema.copy() + Schema((
TextField('text‘, required = False,
widget = RichWidget(label=‘Body Text’)
),
ImageField(‘image‘, required = False,
widget = ImageWidget(label=‘Lead Image’)
),

24. From Archetypes To Dexterity
Improved Content Type Building Framework

25. Fields and Widgets

26. Dexterity Behaviors
Reusable components that can be
enabled on a per-type basis
through enumeration in the FTI.

27. Dexterity Behaviors Example

28. Deco is Coming

29. Diazo : Theming Engine

30. Diazo Concept

32. Plone API
1. Portal 3. Users
2. Content 4. Groups
from plone import api
portal = api.portal.get()
catalog =
api.portal.get_tool(name="portal_catalog")
user = api.user.create(email='alice@plone.org')

33. SQL Integration
1. Database Adapter + Z SQL Method
• mysqldbda / psycopg
2. ORM (SQLAlchemy)
• ContentMirror
3. Pickle
• RelStorage

34. Considerations
1. Product vs Framework
2. ZODB: a Double-edged Knife
3. Positioned as Enterprise Grade
4. Resource Availability
5. Integration Issues
