Define a content type

entry template with link

Locomotive allows you to create content types without imposing a specific pre-built structure. No SQL knowledge is required here.

Your content types can then be used directly in your Liquid templates.

Generate it with Wagon

Wagon provides you the generate command to help you to create the YAML file describing your content type.

cd ~/workspace/my_first_site
wagon generate content_type events title:string description:text event_date:date

It will generate 2 files:

• app/content_types/events.yml
• data/events.yml

The first one contains the content_type declaration, the second contains sample data so that you can test your site with fake data. Some random data have been added.

Description of the YAML file

Here are the properties you can use on app/content_types/*.yml files. All the content types should be plural filenames.

Example of an Article content type:

name: Articles
description: Just a simple blog module
order_by: posted_at
order_direction: desc
slug: articles
label_field_name: title
fields:
- title:
    label: Title
    type: string
    hint: The title of the article
- posted_at:
    label: Posted at
    type: date
    hint: The date when the article has been or will be posted.
- body:
    label: Body
    type: text
    text_formatting: html
    hint: The body of the article
