mongoid-arraylist includes two methods on your model, that makes it really simple to deal with mongodb arrays. No need for custom form's or controller logic to deal with adding items to a mongodb array.
It defines getters and setters on your model for field_list. Given a comma seperated string, it will split the string and save each item to a mongodb array.
Add this line to your application's Gemfile:
gem 'mongoid-arraylist'
And then execute:
$ bundle
Or install it yourself as:
$ gem install mongoid-arraylist
#app/models/post.rb
require 'arraylist'
class Post
include Mongoid::Document
include Mongoid::ArrayList
field :tags, type: Array, default: []
list_field :tags
end
post = Post.new
post.tags_list = 'tag1, tag2, tag3'
=> "tag1, tag2, tag3"
post.tags
=> ["Tag1", "Tag2", "Tag3"]
post.tags_list
=> "Tag1, Tag2, Tag3"
In your view:
<%= f.label :tags_list %><br />
<%= f.text_field :tags_list %>
