simplon.plone.currency
A package to add currency handling support to a Plone site. Site managers can enable any known currency in a site and manage the currency rates. This product is not very useful by itself but is meant to be used as a component by products that need to deal with different currencies.
Installing
This package is made to be used as a normal python package within Zope 2.10 and needs Plone 3.0 or later.
First you need to install this package in the python path for your Zope instance. This can be done by installing it in either your system path packages or in the lib/python directory in your Zope instance.
After installing the package it needs to be registered in your Zope instance. This can be done by putting a simplon.plone.currency-configure.zcml file in the etc/pakage-includes directory with this content:
<include package="simplon.plone.currency" />
or, alternatively, you can add that line to the configure.zcml in a package or Product that is already registered.
Installing with buildout
If you are using buildout to manage your instance installing simplon.plone.currency is even simpler. You can install it by adding it to the eggs line for your instance:
[instance]
eggs = simplon.plone.currency
zcml = simplon.plone.currency
The last line tells buildout to generate a zcml snippet that tells Zope to configure simplon.plone.currency.
Managing currencies
In order to manage currencies you first need to install the package in your Plone site. You can do this using the standard Add/Remove Products page in the Plone site setup. You need to install the 'Currency support' product.
After installing the package in your site a new Currencies option will be available in the site setup. This is where you can manage your currencies.
Currencies can be added using the 'Add currency' button. You only need to select the currency and the conversion rate: the currency description and symbol will be configured automatically.
You have to select a single currency as the 'main currency'. This is the currency against which all conversion rates are defined. You can not edit or remove the main currency: its rate is fixed to 1.0 as reference value for all rates.
