MishkaBlog.Plugins.Installer (Mishka Blog v0.0.1)

Copy Markdown View Source

Installs the blog onto one site, when asked.

Subscribing to installer:extension:install is the whole declaration: the installer's own registry now knows this extension exists, under :mishka_blog, at priority 50, and :extra below is what the picker draws. Nothing is registered anywhere else, and there is no list of extensions to keep in step with this file.

A SITE IS NEVER SET UP BEHIND SOMEBODY'S BACK. This answers a request naming a site; it does not listen for a site being created. A site added to a running CMS gets its own core content and nothing else until an admin asks for the blog from the Blog menu — which is the only honest default, because a site may be a landing page that will never have a blog.

The request's :actor is whoever pressed the button and must hold what MishkaCmsCore.Runtime.ExtensionProvision.required/1 names. A request with no actor is the install wizard's own run and is answered only until the CMS is installed (MishkaCmsCore.Install.installed?/0); after that it is refused like an actor holding nothing.

Types

error_return()

@type error_return() ::
  {:error, [%{action: atom(), field: atom(), message: String.t()}]}

okey_return()

@type okey_return() :: {:ok, struct() | map() | module() | [any()]}

Functions

call(payload)

Installs the blog when the payload names it, and hands the payload on untouched when it does not.

The report goes back in :reports rather than as the reply itself, because every plugin on this event sees every call: replying with the report would make the next plugin's payload a report.

child_spec(init_arg)

Returns a specification to start this module under a supervisor.

See Supervisor.
