# Create a slug system
|
|
|
|
This guide will explain how to create a slug system for a Post, Article or any Content Type you want.
|
|
|
|
## Create attributes
|
|
|
|
To start building your slug system you need a `string` field as a **base** for your slug, in this example we will use `title`.
|
|
|
|
You will also need another `string` field that contains the slugified value of your `title`, in this case we will use `slug`.
|
|
|
|
|
|
|
|
## Configure the layout for the content editor
|
|
|
|
Let's configure the layout of the **edit page** to make it more user friendly for the content editor.
|
|
|
|
- Click on the **Article** link in the left menu.
|
|
- Then on the `+ Add New Article` button.
|
|
- And finally on the `Configure the layout` button.
|
|
|
|
Here we will be able to setup the `slug` field.
|
|
|
|
- Click on the `slug` field.
|
|
- At the bottom of the page, edit the **placeholder** value to `Generated automatically based on the title`.
|
|
- And click **OFF** for **Editable field** option.
|
|
- Don't forget to save your updates.

## Auto create/update the `slug` attribute
|
|
|
|
For that you will have to install `slugify` node module in your application.
|
|
|
|
When it's done, you have to update the life cycle of the **Article** Content Type to auto complete the `slug` field.
|
|
|
|
**Path —** `./api/article/models/Article.js`

```js
|
|
const slugify = require('slugify');
|
|
|
|
module.exports = {
|
|
beforeSave: async model => {
|
|
if (model.title) {
|
|
model.slug = slugify(model.title);
|
|
}
|
|
},
|
|
beforeUpdate: async model => {
|
|
if (model.getUpdate() && model.getUpdate().title) {
|
|
model.update({
|
|
slug: slugify(model.getUpdate().title),
|
|
});
|
|
}
|
|
},
|
|
};
|
|
```

```js
|
|
const slugify = require('slugify');
|
|
|
|
module.exports = {
|
|
beforeSave: async (model, attrs, options) => {
|
|
if (options.method === 'insert' && attrs.title) {
|
|
model.set('slug', slugify(attrs.title));
|
|
} else if (options.method === 'update' && attrs.title) {
|
|
attrs.slug = slugify(attrs.title);
|
|
}
|
|
},
|
|
};
|
|
```

## Fetch article by `slug`
|
|
|
|
Then you will be able to fetch your **Articles** by this slug.
|
|
|
|
You will be able to find your articles by slug with this request `GET /articles?slug=my-article-slug`
