goooooouwa / render added style on added tenderers for the selected package.js

Created May 19, 2014 06:51

render added style on added tenderers for the selected package. This feature is useless after package selection is replaced by company search bar, since no concept of selected package any more.

+$scope.companiesLoaded = function(){
+  angular.forEach($scope.selectedPackage.tenderers, function(tenderer, key){
+    var matchedCompanies = $.grep($scope.companies, function(company){ return (company.id == tenderer.company_id); });
+    if( matchedCompanies.length > 0){
+      matchedCompanies[0].selected = true;
+      matchedCompanies[0].added = true;
+    }
+  });

goooooouwa / find all companies with no contact.rb

Last active August 29, 2015 14:01

active record query to find all companies with no contact

	# in English: return all companies that have a contact whose id is nil.
	# why this will work is because the "includes" method will join the two tables( companies and contacts) into one table.
	# for those companies who has no contacts, the record's contact is null.
	Company.includes(:contacts).where(contacts: {id: nil})

goooooouwa / Create a new object from prototype.js

Last active August 29, 2015 14:02

Javascript does not have class object, what it has to allow Inheritance is prototype object, which is just another object. The way to create an new object from a prototype object is to define a constructor function for the new object and decorate the prototype property( which is an object) of the constructor function( which is also object in jav…

	// 1. define a constructor function for the new object:
	var objectConstructor = function(){
	this.objAttr = "objAttr";
	this.objMethod = function(){
	alert("obj method");
	}
	}

	// 2. decorate the prototype property of the constructor function
	objectConstructor.prototype.protoAttr = "protoAttr";
