Global template variables
These variables are always available for rendering in templates.
zotonic_version
The version of Zotonic, for example "1.0-dev".
zotonic_dispatch
An atom with the name of the dispatch rule that was applied to render the current page.
zotonic_dispatch_path
A list containing the request path used as initial input for the dispatcher.
The path is split on / and after an optional rewrite. This means that the
list doesn’t contain the language prefix. For example, the path
/en/foo/bar?a=b will give the list [<<"foo">>, <<"bar">>].
zotonic_dispatch_path_rewrite
Same as zotonic_dispatch_path, but set to the path after an optional internal
request rewrite inside the dispatcher. For example if a resource has its
page_path set to /foo and the requested path is /en/foo then the
zotonic_dispatch_path will be set to [<<"foo">>] and the
zotonic_dispatch_path_rewrite could be set to something like
[<<"page">>, <<"1234">>, <<"foo-slug">>].
z_language
The currently selected language. This an atom, for example: en.
q
A key/value list containing the current request’s query variables. For GET requests, these are the arguments passed from the query string (e.g. ?foo=bar); for POST requests, these are also the values posted in the POST form. For more access to the raw request data, look at the m_req model.
now
The UTC date and time in Erlang tuple notation, for instance {{2014,4,17},{13,50,2}}.
m
m is not really a value, but it’s an indicator to trigger a lookup in one of Zotonic’s Models. For instance the m_rsc model is always exposed and can be used like this {{ m.rsc[123].title }}.
true, false, and undefined
The values true, false and undefined are predefined.
