Re: [Model-Glue] MG Error Handling

Mon, 16 Sep 2013 06:38:17 -0700 

So, the process is:
User Initiates some action.
Action results in either FORM or URL parameters sent to /index.cfm
The value of the EVENT parameter determines which Model Glue event runs
The Model Glue event broadcasts messages
Zero or More controller functions are configured to listen to that message and do something 
The Controller functions are passed the entire event object.
The Controller functions may pass all/some/none of the values to any number of Model objects. 
The Controller functions may set all/some/none variables in the Event object
The Event configuration may execute Zero or More views.
The Views receive the entire event object.
So, in a nutshell, the event object is the container where all of the state (Variables) is contained. Individual arguments are not passed to controller functions nor to view pages.
Model Glue does not manage your model objects and does not know what arguments are passed in there.

Thanks, I guess i have a problem grasping getting varibles based on where the error occured.
so the view -> controller -> cfc that runs query in the model folder. so there places if the cfc fails i want to know what variables were pasted into it from the controller. if the controller failed i want to know what variables were passed to it from the view.
I see where the form scope might show me when an error will occur from view to controller. would arguments scope show me the arguments in a cfc if that fails?

you could use event.getAll()
But a fair warning, it will get everything inside ModelGlue. Which could be quite a bit of stuff. 

I usually dump out the CGI, Form, URL, Session

Currently I have Error Handling like below but i was wondering how can i add variables/arguments form post to the below email. So if and error happens on a controller or cfc it would dump out all the agruments that were inputed. Same with something like a page so i can figure out and replicate what happened before i used <cfdump var="#arguments#"> or <cfdump var="#attributes#"> (old fusebox frame work) is there something i can set to get it to dump out variables?
