Help I just don’t understand what is happening I am getting this error, Uncaught TypeError: Cannot read property ‘map’ of undefined, if I console.log(this.data.probandera) I get an array of objects, {_id: “sdsafsad”, Cuando : “asdafsada”} with that format… but I just dont know how to iterate in them, followed the manual but I always land in the same error… HELP?
C.Testing = React.createClass({
mixins:[ReactMeteorData],
getMeteorData(){
var dato = {} let carajo = Meteor.subscribe("probando");
if (carajo.ready()){ dato.probandera = L.Probando.find({}).fetch(); }
return dato;},
Sub(e){
e.preventDefault();
var nombre = e.target.nombre;
L.Probando.insert({Cuanto : nombre.value}, (err,sub)=>{
if (err){ console.log(err); } else { console.log(sub); nombre.value = ""; } } );},
renderTasks(){
return this.data.probandera.map((proban)=>{
/* THE UPPER LINE GIVES ME ERROR */
});
},
render: function() {
return (
<form onSubmit={ this.Sub }>
Click me
<ul> { this.renderTasks() } </ul> </div> );}
});
