AWA_Blogs

Blogs module

Introduction

The blogs plugin is a small blog application which allows users to publish articles. A user may own several blogs, each blog having a name and its own base URI. Within a blog, the user may write articles and publish them. Once published, the articles are visible to anonymous users.

The blogs plugin uses the ] and ] modules to allow to associate tags to a post and allow users to comment on the articles.

Model

Integration

The Blog_Module manages the creation, update, removal of blog posts in an application. It provides operations that are used by the blog beans or other services to create and update posts. An instance of the Blog_Module must be declared and registered in the AWA application. The module instance can be defined as follows:

type Application is new AWA.Applications.Application with record
   Blog_Module : aliased AWA.Blogs.Modules.Blog_Module;
end record;

And registered in the Initialize_Modules procedure by using:

Register (App    => App.Self.all'Access,
          Name   => AWA.Blogs.Modules.NAME,
          URI    => "blogs",
          Module => App.Blog_Module'Access);

Blog Beans

Several bean types are provided to represent and manage the blogs and their posts. The blog module registers the bean constructors when it is initialized. To use them, one must declare a bean definition in the application XML configuration.
