TGPriFlash 0.1.2

A TurboGears flash implementation that supports multiple priority levels.

TGPriFlash is a TurboGears flash implementation that supports multiple priority levels.

Install

Install with setuptools:

$ easy_install TGPriFlash

or download from http://pypi.python.org/pypi/TGPriFlash

Usage

Out of the box, 3 levels are defined (FLASH_INFO, FLASH_WARNING, FLASH_ALERT) but you can ignore these and use any integer values you like as the flash priority levels.

To “magically” replace (aka monkey patch) turbogears.flash() with this one, just add this import to your start-project.py:

import tg_pri_flash.flash

Within your project you can import turbogears.flash as normal:

from turbogears import flash

You’ll want to replace the tg_flash line in your master template:

<div py:if="tg_flash" class="flash" py:content="tg_flash"></div>

with something like this:

<div py:if="tg_flash and tg_flash[1]==0" class="flash_ok" py:content="tg_flash[0]"></div>
<div py:if="tg_flash and tg_flash[1]==1" class="flash_warning" py:content="tg_flash[0]"></div>
<div py:if="tg_flash and tg_flash[1]==2" class="flash_alert" py:content="tg_flash[0]"></div>

You would then define CSS definitions for each of the classes.

In your controller you can call flash() with a second argument, a positive integer:

flash( _(u"There was an error"), 2 )

or, using the built-in constants:

from tg_pri_flash.flash import FLASH_ALERT
flash( _(u"There was an error"), FLASH_ALERT )
