How to call function from controller?

[can2nac]

Hi,

let's say i have 

-module(sns_main_controller, [Req]) which processes web requests. It also has some additional functions which i would like to call.

i can call sns_main_controller:module_info() and it returns pretty much everything, but all non /0 functions have +1 extra argument. For example, {checkCashe,4} instead of {checkCashe,3} as in description.

I tried to call function with no luck:

(sns@can2nac-laptop)12> sns_main_controller:chec   

chechCache/4  checkCashe/4  

(sns@can2nac-laptop)12> sns_main_controller:checkCashe(a,b,c,d).

** exception error: no function clause matching sns_main_controller:checkCashe(a,b,c,d) (/home/can2nac/projects/sns/src/controller/sns_main_controller.erl, line 6)

(sns@can2nac-laptop)13> sns_main_controller:checkCashe(b,c,d).  

** exception error: undefined function sns_main_controller:checkCashe/3

 How to call function from controller and what is this extra argument?

best,

The best way to call these controller functions is by using API calls found here:

http://chicagoboss.org/doc/api-controller.html

API calls:

{redirect, Location}

or 

{action_other, OtherLocation}

or

{render, OtherLocation}

I would like to call controller function from my code, not from controller

The extra argument is the [Req] as defined in the the module definition.

Here are some slides I made up for a talk a few years back that show how parameter modules *really* work:

Thanks. I may move required functions to another custom module. This would work for me, but I appreciate you help.

Thanks
