Module: Waves::ResponseMixin

Included in:
Controllers::Mixin, Helpers::Basic, Waves::Resources::Paths, Views::Mixin
Defined in:
lib/runtime/response_mixin.rb,
lib/layers/mvc/extensions.rb

Overview

Defines a set of methods that simplify accessing common request and response methods. These include methods not necessarily associated with the Waves::Request and Waves::Response objects, but which may still be useful for constructing a response. This mixin assumes that a @request@ accessor already exists.

Instance Method Details

#app ⇒ Object 



40
 
# File 'lib/runtime/response_mixin.rb', line 40

def app ; eval(  "::#{app_name.to_s.camel_case}" ) ; end

#app_name ⇒ Object

access stuff from an app



39
 
# File 'lib/runtime/response_mixin.rb', line 39

def app_name ; self.class.rootname.snake_case.to_sym ; end

#attributes ⇒ Object

Attributes are just the query elements specific to the model associated with the current resource.

# File 'lib/layers/mvc/extensions.rb', line 46

def attributes
  query[ model_name ]
end

#basename(str = nil) ⇒ Object

these take strings or operate on the path by default



46
 
# File 'lib/runtime/response_mixin.rb', line 46

def basename( str = nil ) ; ( str or path ).sub(/\.([^\.]+)$/,'') ; end

#captured ⇒ Object

Elements captured the path



22
 
# File 'lib/runtime/response_mixin.rb', line 22

def captured ; @captured ||= traits.waves.captured ; end

#extension(str = nil) ⇒ Object

# File 'lib/runtime/response_mixin.rb', line 48

def extension( str = nil )
  ( m = ( str or path ).match(/\.([^\.]+)$/) ) ? m[1] : nil
end

#log ⇒ Object

Access the Waves::Logger.



37
 
# File 'lib/runtime/response_mixin.rb', line 37

def log; Waves::Logger; end

#model ⇒ Object

Returns the model corresponding to this controller by naively assuming that model_name must be correct. This allows you to write generic controller methods such as:

model.find( name )

to find an instance of a given model. Again, the plurality of the controller and model must be the same for this to work.



35
 
# File 'lib/layers/mvc/extensions.rb', line 35

def model; app::Models[ model_name.intern ]; end

#model_name ⇒ Object

Returns the name of the model corresponding to this controller by taking the basename of the module and converting it to snake case. If the model plurality is different than the controller, this will not, in fact, be the model name.



26
 
# File 'lib/layers/mvc/extensions.rb', line 26

def model_name; self.class.basename.snake_case; end

#params ⇒ Object

Both the query and capture merged together

# File 'lib/runtime/response_mixin.rb', line 25

def params 
  query = captured ? request.query.merge( captured.to_h ) : request.query
  @params ||= Waves::Request::Query.new( query ) 
end

#paths(rname = nil) ⇒ Object

# File 'lib/runtime/response_mixin.rb', line 41

def paths( rname = nil )
  ( rname.nil? ? resource.class.paths : app::Resources[ rname ].paths ).new( request )
end

#query ⇒ Object

Access to the query string as a object where the keys are accessors You can still access the original query as request.query

# File 'lib/layers/mvc/extensions.rb', line 39

def query
  @query ||= Waves::Request::Query.new( 
    Waves::Request::Utilities.destructure( request.query ) )
end

#redirect(location, status = '302') ⇒ Object

Issue a redirect for the given location.



35
 
# File 'lib/runtime/response_mixin.rb', line 35

def redirect(location, status = '302'); request.redirect(location, status); end

#render(path, assigns = {}) ⇒ Object

def render( path, assigns = {} )
  Waves::Views::Base.new( request ).render( path, assigns )
end

#resource ⇒ Object

# File 'lib/runtime/response_mixin.rb', line 13

def resource ; traits.waves.resource ; end

#response ⇒ Object

Access the response.

#traits ⇒ Object

def traits ; request.traits ; end
