Passing information between main Controller & Prep

S3REST

 There is also a '''post-processing hook''' (response.s3.postp) that allows you to execute something directly after the REST request has been executed, but before the shn_rest_controller returns. The post-hook function will be called with the current S3RESTRequest and the output dict of its execution as arguments.
 
+==== Passing information between main Controller & Prep ====
+Scope normally means that these 2 sections can only talk to each other via globals or the Request object.
+
+If you need to pass data between them, you can use this trick:
+{{{
+vars = {} # the surrounding dict
+def prep(r, vars):
+    vars.update(x=y) # the actual variable to pass is x
+    return True
+
+response.s3.prep = lambda r, vars=vars: prep(r, vars)
+
+output = shn_rest_controller(module, resource)
+
+x = vars.get(x, None)
+}}}
+
+An example usage is in {{{controllers/gis.py}}} for location()
