ember.js - Ember action : set property of only target of #each -

i have few actions i'm placing on each item in loop. action reveals of book-covers, instead of 1 want target.

http://guides.emberjs.com/v2.0.0/templates/actions

looks can pass parameter, i'm not sure of syntax.

i've done before in earlier version , remember using this or should

{{action 'showcover' book}} ... ?

controller

import ember 'ember';  export default ember.controller.extend( {    actions: {     showcover(book) { // ?       this.set('covervisible', true); // or       this.toggleproperty('covervisible');     },     ...   }  }); 

other thoughts...

  actions: {     showcover(book) {       // setting *route in general* covervisible:true - not want       this.set('covervisible', true);       // can see class - route...       console.log(this);       // can see model of route...       console.log(this.model);       // , can see book object...       console.log(book);        // how set book object???        // expect book.set('property', true) etc.        console.log(book.covervisible);       console.log(this.covervisible);     }   } 

template

{{#each model |book|}}      <li class='book'>         <article>             {{#if book.covervisible}}             <figure class='image-w book-cover'>                 <img src='{{book.cover}}' alt='cover {{book.title}}'>             </figure>             {{/if}}              ...              {{#if book.cover}}             {{#unless book.covervisible}}             <div {{action 'showcover'}} class='switch show-cover'>                 <span>show cover</span>             </div>             {{/unless}}             {{/if}}  {{/each}} 

also - please suggest title if can think of more succinct one.

@sheriffderek, have provided solution in question itself. can pass additional parameters after action name. like:

<button {{action "showcover" book}}>show cover </button>
