Plain Record Build Status

Plaint Record is a data persistence, which use human editable and readable plain text files. It’s ideal for static generated sites, like blog or homepage.

If you want to write another static website generator, you don’t need to write another file parser – you can use Plain Record.

How To

For example we will create simple blog storage with posts and comments.

  1. Add Plain Record to your application Gemfile:

    gem "plain_record"
  2. Set storage root – dir, which will contain all data files:

    PlainRecord.root = 'data/'
  3. Create Post class, include Plain::Resource module, set glob pattern to posts files and define fields:

    class Post
     include Plain::Resource
     entry_in '*/'
     virtual :name,     in_filepath(1)
     virtual :comments, many(Comment)
     field   :title     default("Untitled")
     field   :tags      default([])
     field   :created   type(Time)
     text    :summary
     text    :content
  4. Create new post file data/first/ Fields will be saved as YAML and text will be placed as plain text, which is separated by 3 dashes:

    title: My first post
    tags: test, first
    It is short post summary.
    And this is big big post text.
    In several lines.
  5. Also you can use files with list of entries. For example, comments:

    class Comment
     include Plain::Resource
     list_in '*/comments.yml'
     virtual :post_name, in_filepath(1)
     virtual :post,      one(Post)
     field   :author
     field   :comment

    You can’t use text fields in list files.

  6. List files is a just YAML array. For example, data/first/comments.yml:

    \- author: Anonymous
       comment: I like it!
    \- author: Friend
       comment: You first post it shit.
  7. Get all post:

    Post.all # will return array with our first post
  8. Get specific entries:

    Comment.all(author: 'Anonymous')
    Post.all(title: /first/)
    Post.all { |i| i.tags.length == 2 }
  9. To get one entry use first method, which also can take matchers. You can access for fields and text by methods with same name:

    post = Post.first(title: /first/)
    post.file    #=> "data/first/"    #=> "first"
    post.title   #=> "My first post"
    post.tags    #=> ["test", "first"]
    post.summary #=> "It is short post summary."
  10. You can also change and save entries:

    post.title = 'First post'
  11. And delete it (with empty dirs in it file path):
