In many scenarios it would be nice if we can provide some dynamic actions to report (classical) region, which can be handled via Ajax calls, rather then submitting a whole page – these actions could include:
Often it is necessary to print an object to debugging log. This small utility function can help to print all properties:
import inspect, pprint
props=filter(lambda t: not t.startswith('__'),
inspect.getmembers(object, lambda m: not inspect.ismethod(m)))
I ‘ve recently created multiselect plugin for APEX 4.1 – there is still little information about how exactly write APEX plugins, and some aspects – like cascading LOV, I have not found explained anywhere, so I’d like to share my experiences here:
What You Need
To write plugin you will need:
- Oracle Database and APEX running somewhere – the installation manual for APEX is very good and you can go step by step according to it
- Knowledge of PL/SQL – it is good to have PL/SQL Reference at your hand
- Reference documentation for APEX 4.1 API
- Some knowledge of APEX and also some basic knowledge of plugins – try some available tutorials you can find on web – this article will focus on rather specific issues within Item plugin.
- Oracle SQL/Developer (or other development tool)- to write PL/SQL – optional, if you are PL/SQL god and can write correct code by heart – if you struggling with PL/SQL like me this is an invaluable helper.
Visual Python or vpython is python library for simple 3D animation, especially useful for animation of simple physical scenes – like pendulum, ball on a spring, movement in gravitational field etc. It is fairly simple to use and gives quite nice animations, which can demonstrate some laws of physics. I actually spot this package, when I saw an article about physics in popular mobile game “Angry Birds – Space”. In that article they had been arguing about physics laws in the game and also referred to vpython, where they made some experiments. I told myself I have to try it myself, so I’ve created small program using vpython. Continue reading Having 3D fun with Visual Python
Aptana studia is a plugin to Eclipse, which contains many useful modules (like PyDev) and amongst many also GIT module. However this module is different than EGit ( and EGit cannot be installed because it conflicts with Aptana Git)so manual on Github is not applicable. So how does it work? On my recent project I’ve tried to use it and here is quick guide how to create project and push it to Github. Continue reading Aptana Studio And Git/Github
