60 <p>The <strong>Zope Component Architecture</strong> (aka ZCA) is used by the Pyramid framework “under the hood” to handle interfaces, |
|
61 adapters and utilities. You don’t <strong>have to</strong> use it in your own applications. But you can.</p> |
|
62 <p>The ZCA is mainly adding elements like <strong>interfaces</strong>, <strong>adapters</strong> and <strong>utilities</strong> to the Python language. It |
|
63 allows you to write a framework or an application by using <strong>components</strong> which can be extended easily.</p> |
|
64 <p>You will find several useful resources about ZCA concepts on the internet.</p> |

|
67 <p>In ZCA, a <strong>utility</strong> is a <strong>registered</strong> component which provides an <strong>interface</strong>. This interface is the |
|
68 <strong>contract</strong> which defines features (list of attributes and methods) provided by the component which implements it.</p> |
|
69 <p>When a Pyramid application starts, a <strong>global registry</strong> is created to register a whole set of utilities and |
|
70 adapters; this registration can be done via ZCML directives or via native Python code. |
|
71 In addition, PyAMS allows you to define <strong>local utilities</strong>, which are stored and registered in the ZODB via a <strong>site |
|
72 manager</strong>.</p> |

75 <h2>Defining site root<a class="headerlink" href="#defining-site-root" title="Permalink to this headline">¶</a></h2> |
|
76 <p>One of PyAMS pre-requisites is to use the ZODB, at least to store the site root application, it’s configuration and a |
|
77 set of local utilities. <a class="reference internal" href="site.html#site"><span class="std std-ref">PyAMS site management</span></a> describes application startup and <strong>local site manager</strong> initialization process.</p> |
|
78 <p>This site can be used to store <strong>local utilities</strong> whose configuration, which is easily available to site |
|
79 administrators through management interface, is stored in the ZODB.</p> |

83 <p><strong>Global utilities</strong> are components providing an interface which are registered in the global registry. |

242 <p>An adapter can also be a multi-adapter, when several input objects are requested to provide a given interface. For |
|
243 example, many adapters require a context and a request, eventually a view, to provide another feature. This is how, |
|
244 for example, we define a custom <em>name</em> column in a security manager table displaying a list of plug-ins:</p> |

264 <p>A <strong>vocabulary</strong> is a custom factory which can be used as source for several field types, like <em>choices</em> or <em>lists</em>. |
|
265 Vocabularies have to be registered in a custom registry, so PyAMS_utils provide another annotation to register them. |
|
266 This example is based on the <em>Timezone</em> component which allows you to select a timezone between a list of references:</p> |
