# Preparing the database
|
|
|
|
The next step is to create and prepare the database. Because DEV is a Rails
|
|
application, we have built-in tools to help us.
|
|
|
|
We can use Rails to create our database, load the schema, and add some seed
|
|
data:
|
|
|
|
```shell
|
|
rails db:setup
|
|
```
|
|
|
|
Note: If you've already run `bin/setup`, this will have already been done for
|
|
you.
|
|
|
|
`db:setup` actually runs the following rake commands in order so alternatively,
|
|
you could run each of these to produce the same result:
|
|
|
|
```shell
|
|
rails db:create
|
|
rails db:schema:load
|
|
rails db:seed
|
|
```
|
|
|
|
## Seed Data
|
|
|
|
By default, the amount of articles and users generated is quite tiny so that
|
|
contributors experience a quick installation. If you require more data for your
|
|
local installation, you can tune amount of data generated with the environment
|
|
variable `SEEDS_MULTIPLIER`.
|
|
|
|
This variable, which defaults to `1`, allows the developer to increase the size
|
|
of their local DB. For example:
|
|
|
|
```shell
|
|
SEEDS_MULTIPLIER=2 rails db:setup
|
|
```
|
|
|
|
will result in creating double the default amount of items in the database.
|
|
|
|
It's currently used only for `articles` and `users`.
|
|
|
|
It can also be used for `rails db:seed` and `rails db:reset`.
