View Full Version : Read multiple lists with Json

25 Jan 2011, 2:30 PM
I have a scenario where I need to read multiple lists for picklist values. I've tried multiple hasMany entries but it doesn't appear I can have more than one hasMany entries in a model. Simple example below...is it possible to create a model and read the structure below? /Greg

"product": [
{ "product": "MTC", "quantity": "5" },
{ "product": "NTC", "quantity": "15" },
{ "product": "OTC", "quantity": "25" },
{ "product": "XTC", "quantity": "35" }
"status": [
{ "sn": "A1", "ln": "Won" },
{ "sn": "A2", "ln": "Close" },
{ "sn": "A3", "ln": "Lost" }

I'm still struggling with the best way to do this. A little more information....I'm reading the details of a CRM Opportunity. The url returns the detail of the opportunity and the valid picklist values for the updateable fields of the opportunity. I was hoping to use multiple hasMany references in my Detail model but it looks like only one is supported. I did find this thread but I'm unable to get the suggested workaround to work (http://www.sencha.com/forum/showthread.php?115383-Can-t-have-more-than-1-hasMany-association). Is there a fix for this or is there a better way to do this verses making multiple server calls.

Thanks in advance!!! /Greg
