Alternative foreign field for link field?

[hi-ko]

When defining a link (belongsTo or hasMany) the name field will be displayed. Is there a way to change the foreign field to show (e.g. the number field)?
In many cases the name field is not unique.

You can add a new field with type "foreign",

For example Case Number field for Task entity

"fields": {
"caseTest": {
"type": "link"
},
"caseNumber": {
"type": "foreign",
"link": "caseTest",
"field": "number",
"readOnly": true,
"view": "views/fields/foreign-int"
}
},
"links": {
"caseTest": {
"type": "belongsTo",
"foreign": "tasksTest",
"entity": "Case"
}
}

Hi tanya,
thanks for your suggestion. This is what we are already using but ends up in a separate field. Sometimes the users don't want to see the name at all but need the functionality from the link field therfore something like

"fields" : {
    "caseTest" : {
        "type" : "link",
        "field" : "number"
    }
},
"links" : {
    "caseTest" : {
        "type" : "belongsTo",
        "foreign" : "tasksTest",
        "entity" : "Case"
    }
}

would be great. I created ticket 262

Thanks
