Dynamic model count devices by type

Hello Frederic,

I had tried the following code before:

interface Site:ICIM_Collection
"Site where a group of devices is located."
{

     computed attribute unsigned short NumberOfRouters

     "Total number of routers in the site."

     = | Router(ConsistsOf) | ;

}

And got the following errors;

dynmodel: "Site.mdl", line 119: Count can only be used for tables and relationship sets
dynmodel: "Site.mdl", line 119: error in lookup of symbol: Router
dynmodel: Site.mdl: found 2 errors
Compilation aborted due to errors.

I thought I might have done something wrong, but according to your answer the logic is correct. Do you have any idea what might be wrong (maybe a #pragma missing, or a different way of compiling)?

And what do you mean by "you can do this, by intention, not extension (not dynamic) from what I know" ?

Thank you very much for your time.

Cordially,

Isabelle.

Hum ... right, this is because Router is not defined in your model. The syntax actually works, at least with new classes. I do use it.

What version are you running on ?

extension / intention :

http://www.britannica.com/EBchecked/topic/289860/intension

extension : you will need to add an attribute (total number) per class (not dynamic, a new class need a new attribute)

intention : you can get the class dynamicaly and associate a value with it (no need to change anything)

for your information : what you want to achieve here can be done, in "intention", using APG. Dynamically. Every new class in the relationship will appear with the right count.

HTH,

Simply include

refine Router {}

at the start and it will pass the syntax validation of dynamic model.
