# ButterCMS API Ruby Client

## Documentation

For a comprehensive list of examples, check out the [API documentation](https://buttercms.com/docs/api/).

## Setup

To setup your project, follow these steps:

1. Install using `gem install buttercms-ruby` or by adding to your `Gemfile`:

  ```ruby
  gem 'buttercms-ruby'
  ```

2. Set your API token.

  ```ruby
  require 'buttercms-ruby'

  ButterCMS::api_token = "YourToken"

  # Fetch content from test mode (eg. for your staging website)
  # ButterCMS::test_mode = true

  # Set read timeout (Default is 5.0)
  # ButterCMS::read_timeout = 5.0

  # Set open timeout (Default is 2.0)
  # ButterCMS::open_timeout = 2.0
  ```

## Pages

https://buttercms.com/docs/api/?ruby#pages


```ruby
params = {page: 1, page_size: 10, locale: 'en', preview: 1, 'fields.headline': 'foo bar', levels: 2} # optional
pages = ButterCMS::Page.list('news', params)

page = ButterCMS::Page.get('news', 'hello-world', params)

pages = ButterCMS::Page.search('query', params)
```

## Collections

https://buttercms.com/docs/api/?ruby#retrieve-a-collection

```ruby
# list each instance of a given collection with meta data for fetching the next page.
params = { page: 1, page_size: 10, locale: 'en', preview: 1, 'fields.headline': 'foo bar', levels: 2 } # optional
ButterCMS::Content.list('collection1', params)

# list instances for multiple collections, this will not return meta data for pagination control.
ButterCMS::Content.fetch(['collection1', 'collection2'], params)

# Test mode can be used to setup a staging website for previewing Collections or for testing content during local development. To fetch content from test mode add the following configuration:
ButterCMS::test_mode = true
```

## Blog Engine

https://buttercms.com/docs/api/?ruby#blog-engine

```ruby
posts = ButterCMS::Post.all({:page => 1, :page_size => 10})
puts posts.first.title
puts posts.meta.next_page

posts = ButterCMS::Post.search("my favorite post", {page: 1, page_size: 10})
puts posts.first.title

post = ButterCMS::Post.find("post-slug")
puts post.title

# Create a Post.
ButterCMS::write_api_token = "YourWriteToken"
ButterCMS::Post.create({
  slug: 'blog-slug',
  title: 'blog-title'
})

# Update a Post
ButterCMS::Post.update('blog-slug', {
  title: 'blog-title-v2'
})

# Create a page
ButterCMS::Page.create({
  slug: 'page-slug',
  title: 'page-title',
  status: 'published',
  "page-type": 'page_type',
  fields: {
    meta_title: 'test meta title'
  }
})

# update a Page
ButterCMS::Page.update('page-slug-2', {
  status: 'published',
  fields: {
    meta_title: 'test meta title'
  }
})



author = ButterCMS::Author.find("author-slug")
puts author.first_name

category = ButterCMS::Category.find("category-slug")
puts category.name

tags = ButterCMS::Tag.all
p tags

rss_feed = ButterCMS::Feed.find(:rss)
puts rss_feed.data
```


## Fallback Data Store

This client supports automatic fallback to a data store when API requests fail. When a data store is set, on every successful API request the response is written to the data store. When a subsequent API request fails, the client attempts to fallback to the value in the data store. Currently, Redis and YAML Store are supported.

```ruby
# Use YAMLstore
ButterCMS::data_store = :yaml, "/File/Path/For/buttercms.store"

# Use Redis
ButterCMS::data_store = :redis, ENV['REDIS_URL']

# Set logger (optional)
ButterCMS::logger = MyLogger.new
```
