So i have some object with posts, and i'm using v-for to iterate them in the custom ponent, but how to pass data from this object to this ponent, loop is a one thing displaying data i another...

<app-single-post v-for="post in posts" postData="$post"></app-single-post>

This is my ponent declaration. Do i need also some kind of special prop setup? Have the same error, again and again:

Property or method "postData" is not defined

• javascript
• json
• object
• vue.js

• You can pass data into a ponent via 'Props'. See vuejs/v2/guide/ponents.html#Passing-Data-with-Props for more details. Props should also be set as kebab case eg 'post-data' on the html element. – Eilimint Commented May 12, 2017 at 23:09
• what you mean data vie props? can you show some example? – Lukas Commented May 12, 2017 at 23:10

Use the binding syntax.

<app-single-post v-for="post in posts" :post="post" :key="post.id"></app-single-post>

Camel-cased properties need to be converted to kebab-case when they are used as attributes. Also, I added a key. You should always use a key when you use v-for and it is required when you iterate over a custom ponent. Ideally you would want to use a post.id if one is available.

In your ponent, you should have a property defined like this:

export default {
    props:["post"],
    methods: {...},
    etc.
}

To reference the post in your ponent template you can use

 {{post.id}}

and inside methods it would be

this.post
