Deleting a Lead

This may be the shortest chapter. Deleting in Ember is typically handled by an action.

Add a Delete Link

Open up the lead template and add a delete link immediately above the submit button:

// app/assets/javascripts/templates/lead.js.emblem
p
  a.delete href='#' click="delete" delete
  input type='submit' value='Save Changes' click="saveChanges"
  # etc ...

Create the Controller Action

Template actions are handled in the controller, so open up the LeadController and add a delete action:

# app/assets/javascripts/controllers/lead.js.coffee
actions:

  delete: ->
    @get('model').destroyRecord().then =>
      @transitionToRoute 'leads'

// app/assets/javascripts/controllers/lead.js
actions: {

  delete: function() {
    var self = this;
    this.get('model').destroyRecord().then(function() {
      self.transitionToRoute('leads');
    });
  }

}

We call destroyRecord() on the model, which sends a DELETE request to the server. After we delete the record we need to transition back to the leads route.

And that’s it!

Next I’ll cover adding a new lead.
