How to get reference of View in Controller - ember.js

Question

I am using Ember 1.0pre and following Ember suggested application structure (Using Router).
For form validation, I want to call $('form').valid() method on Button click.
So I have following method in my view
validate: function(){
return this.$('form').valid()
}
Action in template file:
<button type="submit" class="btn" {{action doSaveSettings this}}>Save Changes</button>
and doSaveSettings method is in Controller.
How can I get instance of view in controller, for calling validate method?
EDIT:
In controller, this.view is null. I have put {{debugger}} in template and this refers to
<App.XyzController:ember1062> and this.view is null.

Answer 1

The default target of actions have been changed from the view to the router in ember 0.9.8.1 (I believe). To set the target to the view you need to override it like this
<button type="submit" class="btn" {{action doSaveSettings target="view"}}>Save Changes</button>
edit: Your controllers should not know about the view.

Answer 2

In ember the purpose of a view is only i repeat is only to handle events or to create reusable components
i would not suggest this since there is always a reason why views are not meant to be accessed from controller and its good to follow it, however if you really do want to use it you could do the below two ways:
I dont know if u r using ember-cli or ember but the logic is same. The answer however is for ember-cli
//Inside appname/controller/your-conroller.js
import reqdView from 'appname/views/your-view';
//Lets assume u want to call a function called validate inside view
//Add this statement inside the controller to run the validate function
reqdView.prototype.validate();
OR
var reqdViewInst = new reqdView();
reqdViewInst.validate();
If you want to validate the view then do the validation inside didInsertElement
export default Ember.View.extend({
didInsertElement:function()
{
this.validate();
},
validate:function()
{
//do your validation
}
});
OR
export default Ember.View.extend({
eventManager: Ember.Object.create({
didInsertElement:function(event, view)
{
view.validate();
}
}),
validate:function()
{
//do your validation
}
});
