Custom record view controller for setting entire record to read-only conditionally

Hi Daniel,

I found a solution, this is what works for me now:
Hope this helps,

initialize: function (options) {
    this._super('initialize', [options]);
	this.model.on('sync', _.bind(this._readonlyFields, this)); //make readonly fields when data gets synced
	this._readonlyFields(); 
	this.events["change input[name=contract_signer_c]"] = '_readonlyFields'; //trigger readonly fields when user changes the field
},

_renderHtml: function() {
	var self = this;
	self._super('_renderHtml');
},

_readonlyFields: function() {
	var self = this;  
	var status_oppty_c = self.model.get('status_oppty_c');		
	
	_.each(self.model.fields, function(field) {   
		switch(field.name){
			case "opportunity_number_c": //make these fields readonly
			case "account_name":
				self.noEditFields.push(field.name); 
				$('.record-edit-link-wrapper[data-name=' + field.name + ']').remove();
				break;
			default: //keep all other fields editable
				break; 
		}
	});

	if (status_oppty_c == "Approved"){ 
		_.each(self.model.fields, function(field) {
			switch(field.name){
				case "contract_signer_c":  //keep all these fields editable when status is Approved
				case "order_type_c": 
				case "send_contract_c":
				case "counter_signed_date_c": 
				case "customer_signed_date_c":
				case "previouscontractdate_c":
				case "specialterms_c":
				case "new_term_c":
				case "date_closed": 
				break; 
				default:  //make all other fields NON editable mode
					self.noEditFields.push(field.name);
					$('.record-edit-link-wrapper[data-name=' + field.name + ']').remove();
			}
		});
	}

},

_dispose: function() {
    this._super('_dispose', []);
}
