gem install has_moderated
And add it to your project's Gemfile
To set up has_moderated in your project, use
rails generate has_moderated:install rake db:migrate
This will generate a Moderation model and a migration for it.
When upgrading, rerun the generator
rails generate has_moderated:install
If there is a new migration file and you have filename conflicts, remove the old one and apply the new one, in case the schema changed.
To moderate one or more attributes, add
has_moderated :attr1, :attr2
to your model.
If you want to moderate the creation of a record (for example, you don't want new blog posts to show up until they are accepted by a moderator), use
You can also specify associations that need to be saved for moderation as well (if moderating the creation of new records) - for example, if a Post has_many :links, and you want to submit these links to moderation as well (note, if you don't, they will be discarded), use
has_moderated_create :with_associations => [:links]
in your Post model (post.rb). This only matters when you use has_moderated_create. You can also use
has_moderated_create :with_associations => :all
to include all associations, but I recommend you explicitly specify them if possible. By default, no associations are included.
To moderate destruction of records, use
To see pending moderations, simply call
You can also see moderations for a specific record. For example, if you have Post model, you can call moderations on it.
post = Post.first post.moderations
Moderation is a normal ActiveRecord model, you can inspect it in rails console to see what it holds. Data (attr_value) is serialized in YAML format and can be deserialized by calling
To accept a moderation, call
to discard (destroy) it, call
I've tested this project using RSpec. You can find the tests in
You can run the tests by running
in the root directory.
You may encounter problems with models that have some sort of non-serializable attributes. This might be something like file attachments, you'll have to try it to see. If you have a problem like that you can extract the problematic attributes into a seperate has_one association. If you moderate create, save that model without the foreign key first, and then use has_moderated_create :with_associations => [:association_name] and add the association (to the existing associated model) before saving the moderated model. If you have questions about this or don't understand what I mean, open an issue here at GitHub and I will explain it further.
