Ruby/WordPress

Too long? tl;dr.

Situation: You’re migrating a big site to WordPress. You don’t want to make 1,000+ posts manually, do you?

Meet Ruby/WordPress. I’ve made a quick little Ruby gem that interfaces with your WordPress database, so you can manipulate it within Ruby. This opens up a whole world of possibilites – the most exciting being Nokogiri, of course.

Here’s a quick code sample that will create 100 new posts!

require 'wordpress'

# Configuration
wp = WordPress.new { host: '127.0.0.1',
                     port: 3306,
                     username: 'test',
                     password: 'test',
                     encoding: 'utf8',
                     database: 'wordpress',
                     wordpress_prefix: 'wp_' }

(1..100).each do |i|
  post = wp.new_post { post_name: "post-#{i}",
                       post_status: 'publish',
                       post_title: "Post #{i}" }
  post.post_content = "This is the content for post #{i}"
  post.save!
end

Note that the configuration must point to a valid WordPress database (and make sure you don’t use one with valuable data… I don’t take responsibility for any lost data. You should be backing up anyways.)

It’s at version 0.0.2, a very early beta at this point, but it can do basic tasks such as creating posts (as shown before) and post querying (albeit, very basic at this stage in development):

wp.query( post__in: [ 1, 5, 8] ).each do |post|
  puts "Post: #{ post.post_title }n"
end
wp.query( post_type: 'custom_post_type', post_parent: 10 ).each do |post|
  puts "Post: #{ post.post_title }n"
end

The ultimate goal of WordPress#query is to be fully compatible with the WP_Query API.

Another feature is post meta manipulation. After you get your post object (WordPress::Post), getting or setting post meta is very easy:

post.post_meta['hello'] = 'world'
puts post.post_meta['hello'] + "n"

Initial support for taxonomies is also included:

puts post.get_the_terms('category').join(', ') + "n"
post.set_post_terms ['love', 'WordPress'], 'category'

Note: WordPress::Post#set_post_terms will overwrite all terms of the given taxonomy, unless you supply the “append” flag:

post.set_post_terms ['love', 'WordPress'], 'category', true

As you can probably tell, this is not a very ideal API, and I am planning on changing it soon.
