import Validation from '../../../components/formValidations';

export default Ember.Route.extend(Validation, {
  model: function(params) {

    if(this.store.hasRecordForId('card-list', params.id)){
        return this.store.peekRecord('card-list', params.id );
    }
  },
  actions:{
    formValidateBeforeNext:function(){

      var model = this.controllerFor(this.routeName).get('model');

      var modelId = model.get("id");

      var payToAmout = model.get('requestedAmount');

      console.log('validation outside ')

      this.validate().then(({model,validations})=>{
        console.log('validation inside ')
        if(validations.get('isValid')){
