Module Sequel::Plugins::XmlSerializer::InstanceMethods
In: lib/sequel/plugins/xml_serializer.rb

Methods

from_xml   from_xml_node   to_xml  

Public Instance methods

from_xml(xml, opts={})

Update the contents of this instance based on the given XML. Accepts the following options:

:name_proc :Proc or Hash that accepts a string and returns a string, used to convert tag names to column or association names.
:underscore :Sets the :name_proc option to one that calls underscore on the input string. Requires that you load the inflector extension or another library that adds String#underscore.

187:         end
from_xml_node(parent, opts={})

Update the contents of this instance based on the given XML node, which should be a Nokogiri::XML::Node instance.

to_xml(opts={}) {|x1 if block_given?| ...}

Return a string in XML format. If a block is given, yields the XML builder object so you can add additional XML tags. Accepts the following options:

:builder :The builder instance used to build the XML, which should be an instance of Nokogiri::XML::Node. This is necessary if you are serializing entire object graphs, like associated objects.
:builder_opts :Options to pass to the Nokogiri::XML::Builder initializer, if the :builder option is not provided.
:camelize:Sets the :name_proc option to one that calls camelize on the input string. Requires that you load the inflector extension or another library that adds String#camelize.
:dasherize :Sets the :name_proc option to one that calls dasherize on the input string. Requires that you load the inflector extension or another library that adds String#dasherize.
:encoding :The encoding to use for the XML output, passed to the Nokogiri::XML::Builder initializer.
:except :Symbol or Array of Symbols of columns not to include in the XML output.
:include :Symbol, Array of Symbols, or a Hash with Symbol keys and Hash values specifying associations or other non-column attributes to include in the XML output. Using a nested hash, you can pass options to associations to affect the XML used for associated objects.
:name_proc :Proc or Hash that accepts a string and returns a string, used to format tag names.
:only :Symbol or Array of Symbols of columns to only include in the JSON output, ignoring all other columns.
:root_name :The base name to use for the XML tag that contains the data for this instance. This will be the name of the root node if you are only serializing a single object, but not if you are serializing an array of objects using Model.to_xml or Dataset#to_xml.
:types :Set to true to include type information for all of the columns, pulled from the db_schema.
