- Defined in:
- lib/apipie/dsl_definition.rb
Overview
this describes the params, it’s in separate module because it’s used in Validators as well

Instance Method Details
#_default_param_group_scope ⇒ Object
where the group definition should be looked up when no scope given. This is expected to return a controller.

#param(param_name, validator, desc_or_options = nil, options = {}, &block) ⇒ Object
Describe method’s parameter
Example:
param :greeting, String, :desc => "arbitrary text", :required => true
def hello_world(greeting)
puts greeting
end

#param_group(name, scope_or_options = nil, options = {}) ⇒ Object
Reuses param group for this method. The definition is looked up in scope of this controller. If the group was defined in different controller, the second param can be used to specify it. when using action_aware params, you can specify :as => :create or :update to explicitly say how it should behave

Describe possible responses
Example:
def_param_group :user do
param :user, Hash do
param :name, String
end
end
returns :user, "the speaker"
returns "the speaker" do
param_group: :user
end
returns :param_group => :user, "the speaker"
returns :user, :code => 201, :desc => "the created speaker record"
returns :array_of => :user, "many speakers"
def hello_world
render json: {user: {name: "Alfred"}}
