Ember Date get Month, Year, and Day

Question

I've searched around but I couldn't find any help.

I want to know if I can get the Day, Month, and Year, and maybe other attributes, from Ember's Date attribute.

For example, in one of my models, I have something like this:

createdAt: DS.attr('string', {
    defaultValue() {
        return new Date();
    }
})

which returns me this format: Tue Feb 23 2016 10:27:10 GMT-0800 (PST)

Is there a way which I can get the "Feb" portion from the whole Date?

I know in pure JS, you can do something like var today = new Date.getMonth(), but that doesn't work, of course, for Ember's date.

Thank you.

Just split the `Date()` as a string and return the second item in the array. — Ellis, Feb 26 '16 at 19:42
var values = this.get('createdAt').split(' '); var mm = values[1]; return mm; this code returns me a blank in ember. — sallyp, Feb 26 '16 at 19:56

Actually Your can make it work using new Date.getMonth() as You said in your question. See the following code:

import DS from 'ember-data';
import Ember from 'ember';

export default DS.Model.extend({
   createdAt: DS.attr('string', {
        defaultValue() {
            return new Date();
        }
    }),
    createdMonth: Ember.computed('createdAt', function(){ 
        return this.get('createdAt').getMonth() + 1 // returns 2 for the current month (February)
    })
});

The next thing You might do is choose a way of converting the number to a month name. Please check this: Get month name from Date

Cheers.

Thanks so much! One question is, did Ember Docs list functions like that ('getMonth, getYear..., getDate) on their website? Or do we just use whatever Javascript has? – sallyp Feb 26 '16 at 20:12
I think we just use whatever Javascript has, because `Date` is comming from JS, not ember. – Dan Cantir Feb 26 '16 at 20:13
Ah okay, have you ever gotten this error: "Uncaught TypeError: this.get(...).getMonth is not a function"? On my website, the data displays once but if I go to another page and go back to it, it disappears. – sallyp Feb 26 '16 at 20:53
