Integrating vue-resource 111 DELETE request 1 deleteStory: function(story){ 2 this.$parent.stories.$remove(story) 3 this.$http.delete('/api/stories/'+story.id ) 4 }, We observe that the delete function works as expected and the story is deleted from the database. 10.3 Enhancing Functionality We should add a couple more features to make our list of stories neat. We can give the user the ability to change the plot and the writer of a story and create new stories. 10.3.1 Edit Stories Let’s start with the first task and give the user some inputs to manipulate the story’s attributes. Two binded inputs should do the job, but we should display them only when the user is editing a story. It seems like the kind of work we did in previous chapters. To define if a story is in edit state we will use a property, editing which will become true when the user hits the ‘Edit’ button. 1 2 3 4 5 6 7 {{story.plot}} 8 9 10 11 12 13 14 15 16 {{story.writer}} 17 18

We use the editStory function to set story.editing to true , so v-if will bring up the inputs to edit the story and hide the ‘Upvote’ and ‘Delete’ buttons. But this approach won’t work. It seems that the DOM isn’t updating after setting story.editing to true. Why this may be happening? It turns out, according to this post from Vue.js blog³ that when you are adding a new property that wasn’t present when the data was observed the DOM won’t update. The best practice is to always declare properties that need to be reactive upfront. In cases where you absolutely need to add or delete properties at runtime, use the global Vue.set or Vue.delete methods. For this reason, we have to initialize the story.editing attribute to false on each story, right after receiving the stories from the server. To do this, we are going to use javascript’s .map() method within the success callback of the GET request. ³http://<strong>vuejs</strong>.org/2016/02/06/common-gotchas/
