class Nimbu::Request::Arguments
Request
arguments handler
Constants
- AUTO_PAGINATION
- CONTENT_LOCALE
Attributes
The request api
Optional arguments
Parameters passed to request
Required arguments
Public Class Methods
Takes api, filters and required arguments
Parameters¶ ↑
:required - arguments that must be present before request is fired
# File lib/nimbu-api/request/arguments.rb, line 42 def initialize(api, options={}) normalize! options @api = api @required = options.fetch('required', []).map(&:to_s) @optional = options.fetch('optional', []).map(&:to_s) end
Public Instance Methods
Check if required keys are present inside parameters hash.
# File lib/nimbu-api/request/arguments.rb, line 82 def assert_required(required) assert_required_keys required, params self end
Check if parameters match expected values.
# File lib/nimbu-api/request/arguments.rb, line 89 def assert_values(values, key=nil) assert_valid_values values, (key.nil? ? params : params[key]) self end
Parse arguments to allow for flexible api calls. Arguments
can be part of parameters hash or be simple string arguments.
# File lib/nimbu-api/request/arguments.rb, line 52 def parse(*args, &block) options = args.extract_options! normalize! options if !args.size.zero? parse_arguments *args else # Arguments are inside the parameters hash parse_options options end @params = options @remaining = extract_remaining(args) extract_pagination(options) extract_content_locale(options) yield_or_eval(&block) self end
Private Instance Methods
Check if required arguments have been set on instance.
# File lib/nimbu-api/request/arguments.rb, line 149 def check_assignment!(options) result = required.inject({}) { |hash, arg| if api.respond_to?(:"#{arg}") && (value = api.send(:"#{arg}")) hash[arg] = value end hash } assert_presence_of result result end
Check if required arguments are present.
# File lib/nimbu-api/request/arguments.rb, line 162 def check_requirement!(*args) args_length = args.length required_length = required.length if args_length < required_length ::Kernel.raise ArgumentError, "wrong number of arguments (#{args_length} for #{required_length})" end end
Find content_locale parameter in options hash
# File lib/nimbu-api/request/arguments.rb, line 121 def extract_content_locale(options) if (value = options.delete(CONTENT_LOCALE)) api.content_locale = value end end
Fine auto_pagination parameter in options hash
# File lib/nimbu-api/request/arguments.rb, line 114 def extract_pagination(options) if (value = options.delete(AUTO_PAGINATION)) api.auto_pagination = value end end
Find remaining arguments
# File lib/nimbu-api/request/arguments.rb, line 108 def extract_remaining(args) args[required.size..-1] end
Check and set all requried arguments.
# File lib/nimbu-api/request/arguments.rb, line 98 def parse_arguments(*args) assert_presence_of *args required.each_with_index do |req, indx| api.set req, args[indx] end check_requirement!(*args) end
Remove required arguments from parameters and validate their presence(if not nil or empty string).
# File lib/nimbu-api/request/arguments.rb, line 130 def parse_options(options) options.each { |key, val| remove_required(options, key, val) } provided_args = check_assignment!(options) check_requirement!(*provided_args.keys) end
Remove required argument from parameters
# File lib/nimbu-api/request/arguments.rb, line 138 def remove_required(options, key, val) key = key.to_s if required.include? key assert_presence_of val options.delete key api.set key, val end end
Evaluate block
# File lib/nimbu-api/request/arguments.rb, line 173 def yield_or_eval(&block) return unless block block.arity > 0 ? yield(self) : self.instance_eval(&block) end
