m_req
This model gives access to the request variables from within a template.
Sometimes you need direct access to request variables in your template. The m_req model is meant for this. It exposes some values from the Cowmachine request record.
Fetching a single value
You can fetch individual values by key, for example:
{{ m.req.host|escape }}
Viewing all request variables
Use the print tag to get a complete overview of all request variables:
{% print m.req|make_list %}
This will show something like:
[{method,<<"GET">>},
{version,{1,1}},
{peer,<<"127.0.0.1">>},
{is_ssl,false},
{host,<<"mysite.test">>},
{raw_path,<<"/en/page/1234?foo=bar">>},
{path,<<"/en/page/1234">>},
{qs,[{<<"foo">>,<<"bar">>}]},
{referrer,<<"http://mysite.test:8000/">>},
{user_agent,<<"Mozilla/5.0 (Macintosh; Intel Mac OS X 10_10_5) AppleWebKit/601.4.4 (KHTML, like Gecko) Version/9.0.3 Safari/601.4.4">>},
{is_crawler,false},
{req_id,525158920},
{headers,[{<<"accept">>,
<<"text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8">>},
{<<"accept-encoding">>,<<"gzip, deflate">>},
{<<"accept-language">>,<<"en-us">>},
{<<"cache-control">>,<<"max-age=0">>},
{<<"connection">>,<<"keep-alive">>},
{<<"cookie">>,
"z_logon=; z_sid=LopWHBmHXCs94virnboZhBHLKV6m1Cga; z_ua=c%3Ddesktop%26u%3D1%26t%3D1%26w%3D1920%26h%3D1200"},
{<<"dnt">>,<<"1">>},
{<<"host">>,<<"mysite.test:8000"},
{<<"referer">>,<<"http://mysite.test:8000/">>},
{<<"user-agent">>,
<<"Mozilla/5.0 (Macintosh; Intel Mac OS X 10_10_5) AppleWebKit/601.4.4 (KHTML, like Gecko) Version/9.0.3 Safari/601.4.4">>}]},
{timezone,<<"UTC">>},
{language,en}]
Please note that all values are raw and not escaped, take care to escape the values before you use them in your templates, using the escape filter.
The make_list filter is used to force the evaluation of the
model; otherwise it would just print {m,req,undefined}.
