m_req

• Module: core

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 Webmachine 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:

[{version,{1,1}},
 {peer,"127.0.0.1"},
 {is_ssl,false},
 {host,"127.0.0.1:8000"},
 {raw_path,"/?foo=bar"},
 {path,"/"},
 {qs,[{"foo","bar"}]},
 {headers,[{"accept",
          "application/xml,application/xhtml+xml,text/html;q=0.9,text/plain;q=0.8,image/png,*/*;q=0.5"},
         {"accept-encoding","gzip, deflate"},
         {"accept-language","en-us"},
         {"connection","keep-alive"},
         {"cookie","z_sid=1RrDIvFVsoyLgtSU62mN; z_pid=HRrAaiPI08Il4Nu4wST1"},
         {"host","127.0.0.1:8000"},
         {"referer","http://localhost:8000/"},
         {"user-agent",
          "Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10_6_4; en-us) AppleWebKit/533.16 (KHTML, like Gecko) Version/5.0 Safari/533.16"}]}]

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 filter-escape filter.

The make_list filter is used to force the evaluation of the model; otherwise it would just print {m,req,undefined}.
