How can i set include_root_in_json to false for all my RoR models?

How can i set include_root_in_json to false for all my RoR models?

I've tried to set ActiveModel::Base.include_root_in_json = false inside application.rb, but it has no effect.

At Rails 4 in "config/initializers/wrap_elements.rb" you can uncomment the following:

ActiveSupport.on_load(:active_record) do
 self.include_root_in_json = true
end

On Rails 3.2.2, this is already set in the initializers:

---config/initializers/wrap_parameters.rb ---

# Disable root element in JSON by default.
ActiveSupport.on_load(:active_record) do
  self.include_root_in_json = false
end

I think you should set ActiveRecord::Base.include_root_in_json = false in config/application.rb

not ActiveModel::Base

Model.to_json method is used to returns a JSON string representing the model and i have used self.include_root_in_json = false in a model itself.

But for the whole application you can try setting ActiveModel::Base.include_root_in_json = false in an initializer.[edit This does not work.]

[edit] ActiveRecord::Base.include_root_in_json = true try adding this line to config/environment.rb file.

I'm not sure if this is true for the later versions of rails but for me (running 2.3.5 atm) there was already a declaration for this setting in /config/initializers/new_rails_defaults.rb where it was set to:

ActiveRecord::Base.include_root_in_json = true

So if you try to set this setting in another place then it might be overridden.

For default system wide config is alway good idea to set variable in initializers, like config/initializers/defaults.rb
