ZODB browser
Project description
The ZODB browser allows you to inspect persistent objects stored in the ZODB, view their attributes and historical changes made to them.
Usage as a standalone project
Install all the dependencies into the source tree with zc.buildout:
python bootstrap.py bin/buildout
Run bin/zodbbrowser specifying either a filename or a ZEO address
bin/zodbbrowser /path/to/Data.fs bin/zodbbrowser --zeo localhost:9080 bin/zodbbrowser --zeo /path/to/zeosock
If you don’t have a spare Data.fs to test with, you can create a new empty one with just the barest Zope 3 scaffolding in it:
bin/zodbbrowser empty.fs --rw
Open http://localhost:8070 in a web browser. Note that there are no access controls; all other users on the local machine will be able to access the database contents.
Or you could try to use easy_install. It may work or it may not, depending on the current state of all the dependencies (buildout.cfg hardcodes dependency version to a known-working-together state, called the “Zope 3.4 Known Good Set”, so buildout-based installs are safer)
easy_install zodbbrowser[app] zodbbrowser /path/to/Data.fs
Command-line options
Run bin/zodbbrowser --help to see a full and up-to-date list of command-line options:
Usage: zodbbrowser [options] [FILENAME | --zeo ADDRESS]
Open a ZODB database and start a web-based browser app.
Options:
-h, --help show this help message and exit
--zeo=ADDRESS connect to ZEO server instead
--listen=ADDRESS specify port (or host:port) to listen on
--rw open the database read-write (allows creation of the
standard Zope local utilities if missing)
Online help
There’s a little ‘help’ link in the bottom-right corner of every page that describes the user interface in greater detail.
Usage as a plugin
Add zodbbrowser to the list of eggs (e.g. in buildout.cfg of your app) and add this to your site.zcml:
<include package="zodbbrowser" />
Rerun bin/buildout, restart Zope and append @@zodbbrowser to the end of the URL to start browsing, e.g. http://localhost:8080/@@zodbbrowser. Or, if you still use ZMI (the Zope Management Interface), look for a new menu item titled “ZODB Browser”.
Alternatives
There’s a package called z3c.zodbbrowser in the Zope svn repository that implements the same idea (but without history browsing) as a GUI desktop application written using wxPython. It doesn’t have a website and was never released to the Python Package Index.
Changes
0.5.1 (2009-11-23)
IMPORTANT BUGFIX: don’t leave old object states lying around in ZODB object cache, which could lead to DATA LOSS (LP#487243).
0.5 (2009-11-23)
Be a bit more tolerant to unpickling errors (show which revision could not be loaded instead of breaking the whole page).
Show full history of OOBTree objects and subobjects (LP#474334).
Change background color of links on hover, to make it clear what object you’ll see when you click, especially when the __repr__ shown contains reprs of subobjects.
Show size of containers next to the “Items” heading (LP#486910).
Show size of containers next to their representation, e.g. “<persistent.dict.PersistentDict object at 0xad0b3ec> (0 items)”.
Pay attention when __name__ is declared as a class attribute (LP#484899).
Show names of directly provided interfaces on objects (i.e. show a better representation of pickled zope.interface.Provides objects).
Pretty-printing of dictionaries (including nested ones).
