Integrating vue-resource 113 1 ready: function() { 2 // GET request 3 this.$http({url: '/api/stories', method: 'GET'}).then(function (response) { 4 var storiesReady = response.data.map(function(story){ 5 story.editing = false; 6 return story 7 }) 8 9 this.$set('stories', storiesReady) 10 }) 11 } Info The .map() method calls a defined callback function on each element of an array and returns an array that contains the results. You can find more information about the .map() method and its syntax Here⁴ The function passes the new attribute inside each story object and then returns the updated story. The new variable storiesReady is an array that contains our updated array with the new attribute on. When the story is under edit, we will give the user two options, to update the story with new values, and to cancel the edit. Form inputs for story editing So, lets move on and add two new buttons that should be displayed only when the user is editing a story. Additionally a new method called updateStory will be created, which updates the current editing story, after the ‘Update Story’ button is pressed. ⁴https://msdn.microsoft.com/en-us/library/ff679976(v=vs.94).aspx
Integrating vue-resource 114 1 2 3 4 Update Story 5 6 7 Cancel 8 9 1 Vue.component('story',{ 2 ... 3 methods: { 4 ... 5 updateStory: function(story){ 6 this.$http.patch('/api/stories/'+story.id , story) 7 //Set editing to false to show actions again and hide the inputs 8 story.editing = false; 9 }, 10 } 11 ... 12 }) Updating story actions Here it is up and running. After the PATCH request is finished successfully, we have to set story.editing to false in order to hide the inputs and bring back the action buttons. 10.3.2 Create New Stories Now for a bit trickier task, we are going to give the user the ability to create a new story and save it to our server. First, we must provide inputs so the new story can be typed in. To make this happen, we will create an empty story and we’ll add it to the stories array using the push() javascript method. We will initialize all the story’s attributes to null, except from editing. We want to immediately manipulate the story, so the editing will be set to true.
