The next lines work fine and I can see the whole object in the console log:
Meteor.subscribe('projects')
var oneProject = Projects.findOne(key1);
console.log(oneProject)
In the console, I can see the oneProject's properties, even the name
property.
Now with the following lines, the result is an error:
Meteor.subscribe('projects')
var oneProject = Projects.findOne(key1);
console.log(oneProject.name)
The error is: "Cannot read property 'name' of undefined".
This is the whole code:
import { Meteor } from 'meteor/meteor';
import { withTracker } from 'meteor/react-meteor-data';
import { Projects } from '/imports/api/projects.js';
import ProjectFormUpdate from './ProjectFormUpdate.jsx';
export default ProjectFormUpdateContainer = withTracker(({ key1 }) => {
Meteor.subscribe('projects')
var oneProject = Projects.findOne(key1);
console.log(oneProject.name)
return {
oneProject:oneProject,
};
})(ProjectFormUpdate);
A subscription in Meteor is asynchronous. This means the data is not always immediately available.
Tracker.autorun(() => {
const sub = Meteor.subscribe('projects');
if (sub.ready()){
const oneProject = Projects.findOne(key1);
console.log(oneProject.name);
}
});
will not try to find the project until the subscription is ready.
