Vue.js: can't orderBy in v-for

Question

I've upgraded to Vue.js 2.0.5 and orderBy in a v-for seems to not be working anymore

<li v-for="c in rooms | orderBy 'last_iteraction'"> 

outputs

• invalid expression: v-for="c in rooms | orderBy 'last_iteraction'"

anyone knows how to solve?

Answer 1

orderBy Filter is removed in vue.js v-2.

Quoted from vue.js docs

Instead of:

<p v-for="user in users | orderBy 'name'">{{ user.name }}</p>

Use lodash’s orderBy (or possibly sortBy) in a computed property:

<p v-for="user in orderedUsers">{{ user.name }}</p>

computed: {   orderedUsers: function () {     return _.orderBy(this.users, 'name')   } }

Answer 2

You can also use vue2 filters package.

1. First install it using npm.

npm install vue2-filters

2. Then, add it in your component or globally.

import Vue from 'vue' import Vue2Filters from 'vue2-filters'    Vue.use(Vue2Filters) 

3. To use one of the predefined methods (such as limitBy, filterBy, find, or orderBy) in your component, you also need to add Vue2Filters.mixin to mixin list:

import Vue2Filters from 'vue2-filters'  export default {   ...   mixins: [Vue2Filters.mixin],   ... } 

4. After that use it in the template

 <li v-for="c in orderBy(rooms,'last_iteraction')"> 

There is a list of predefined filters.check it out.
