Disable input conditionally (Vue.js)

I have an input:

<input 
  type="text" 
  id="name" 
  class="form-control" 
  name="name"  
  v-model="form.name" 
  :disabled="validated ? '' : disabled"
/>

and in my Vue.js component, I have:

..
..
ready() {
  this.form.name = this.store.name;
  this.form.validated = this.store.validated;
},
..

validated being a boolean, it can be either 0 or 1, but no matter what value is stored in the database, my input is always disabled.

I need the input to be disabled if false, otherwise it should be enabled and editable.

Update:

Doing this always enables the input (no matter I have 0 or 1 in the database):

<input 
  type="text" 
  id="name" 
  class="form-control" 
  name="name" 
  v-model="form.name" 
  :disabled="validated ? '' : disabled"
/>

Doing this always disabled the input (no matter I have 0 or 1 in the database):

<input 
  type="text" 
  id="name" 
  class="form-control" 
  name="name" 
  v-model="form.name" 
  :disabled="validated ? disabled : ''"
/>
