- module Helpers
- # Provides a number of methods for turning different kinds of containers into a set of option tags.
- # == Options
- # The <tt>collection_select</tt>, <tt>select</tt> and <tt>time_zone_select</tt> methods take an <tt>options</tt> parameter, a hash:
- #
- # * <tt>:include_blank</tt> - set to true or a prompt string if the first option element of the select element is a blank. Useful if there is not a default value required for the select element.
- #
- # For example,
- #
- # select("post", "category", Post::CATEGORIES, {:include_blank => true})
- #
- # could become:
- #
- # <select name="post[category]">
- # <option></option>
- # <option>joke</option>
- # <option>poem</option>
- # </select>
- #
- # Another common case is a select tag for an <tt>belongs_to</tt>-associated object.
- #
- # Example with @post.person_id => 2:
- #
- # select("post", "person_id", Person.all.collect {|p| [ p.name, p.id ] }, {:include_blank => 'None'})
- #
- # could become:
- #
- # <select name="post[person_id]">
- # <option value="">None</option>
- # <option value="1">David</option>
- # <option value="2" selected="selected">Sam</option>
- # <option value="3">Tobias</option>
- # </select>
- #
- # * <tt>:prompt</tt> - set to true or a prompt string. When the select element doesn't have a value yet, this prepends an option with a generic prompt -- "Please select" -- or the given prompt string.
- #
- # Example:
- #
- # select("post", "person_id", Person.all.collect {|p| [ p.name, p.id ] }, {:prompt => 'Select Person'})
- #
- # could become:
- #
- # <select name="post[person_id]">
- # <option value="">Select Person</option>
- # <option value="1">David</option>
- # <option value="2">Sam</option>
- # <option value="3">Tobias</option>
- # </select>
- #
- # Like the other form helpers, +select+ can accept an <tt>:index</tt> option to manually set the ID used in the resulting output. Unlike other helpers, +select+ expects this
- # option to be in the +html_options+ parameter.
- #
- # Example:
- #
- # select("album[]", "genre", %w[rap rock country], {}, { :index => nil })
- #
- # becomes:
- #
- # <select name="album[][genre]" id="album__genre">
- # <option value="rap">rap</option>
- # <option value="rock">rock</option>
- # <option value="country">country</option>
- # </select>
- #
- # * <tt>:disabled</tt> - can be a single value or an array of values that will be disabled options in the final output.
- #
- # Example:
- #
- # select("post", "category", Post::CATEGORIES, {:disabled => 'restricted'})
- #
- # could become:
- #
- # <select name="post[category]">
- # <option></option>
- # <option>joke</option>
- # <option>poem</option>
- # <option disabled="disabled">restricted</option>
- # </select>
- #
- # When used with the <tt>collection_select</tt> helper, <tt>:disabled</tt> can also be a Proc that identifies those options that should be disabled.
- #
- # Example:
- #
- # collection_select(:post, :category_id, Category.all, :id, :name, {:disabled => lambda{|category| category.archived? }})
- #
- # If the categories "2008 stuff" and "Christmas" return true when the method <tt>archived?</tt> is called, this would return:
- # <select name="post[category_id]">
- # <option value="1" disabled="disabled">2008 stuff</option>
- # <option value="2" disabled="disabled">Christmas</option>
- # <option value="3">Jokes</option>
- # <option value="4">Poems</option>
- # </select>
- #
- module FormOptionsHelper
- # ERB::Util can mask some helpers like textilize. Make sure to include them.
- include ERB::Util
- include TextHelper
- # Create a select tag and a series of contained option tags for the provided object and method.
- # The option currently held by the object will be selected, provided that the object is available.
- # See options_for_select for the required format of the choices parameter.
- #
- # Example with @post.person_id => 1:
- # select("post", "person_id", Person.all.collect {|p| [ p.name, p.id ] }, { :include_blank => true })
- #
- # could become:
- #
- # <select name="post[person_id]">
- # <option value=""></option>
- # <option value="1" selected="selected">David</option>
- # <option value="2">Sam</option>
- # <option value="3">Tobias</option>
- # </select>
- #
- # This can be used to provide a default set of options in the standard way: before rendering the create form, a
- # new model instance is assigned the default options and bound to @model_name. Usually this model is not saved
- # to the database. Instead, a second model object is created when the create request is received.
- # This allows the user to submit a form page more than once with the expected results of creating multiple records.
- # In addition, this allows a single partial to be used to generate form inputs for both edit and create forms.
- #
- # By default, <tt>post.person_id</tt> is the selected option. Specify <tt>:selected => value</tt> to use a different selection
- # or <tt>:selected => nil</tt> to leave all options unselected. Similarly, you can specify values to be disabled in the option
- # tags by specifying the <tt>:disabled</tt> option. This can either be a single value or an array of values to be disabled.
- def select(object, method, choices, options = {}, html_options = {})
- InstanceTag.new(object, method, self, options.delete(:object)).to_select_tag(choices, options, html_options)
- end
- # Returns <tt><select></tt> and <tt><option></tt> tags for the collection of existing return values of
- # +method+ for +object+'s class. The value returned from calling +method+ on the instance +object+ will
- # be selected. If calling +method+ returns +nil+, no selection is made without including <tt>:prompt</tt>
- # or <tt>:include_blank</tt> in the +options+ hash.
- #
- # The <tt>:value_method</tt> and <tt>:text_method</tt> parameters are methods to be called on each member
- # of +collection+. The return values are used as the +value+ attribute and contents of each
- # <tt><option></tt> tag, respectively.
- #
- # Example object structure for use with this method:
- # class Post < ActiveRecord::Base
- # belongs_to :author
- # end
- # class Author < ActiveRecord::Base
- # has_many :posts
- # def name_with_initial
- # "#{first_name.first}. #{last_name}"
- # end
- # end
- #
- # Sample usage (selecting the associated Author for an instance of Post, <tt>@post</tt>):
- # collection_select(:post, :author_id, Author.all, :id, :name_with_initial, :prompt => true)
- #
- # If <tt>@post.author_id</tt> is already <tt>1</tt>, this would return:
- # <select name="post[author_id]">
- # <option value="">Please select</option>
- # <option value="1" selected="selected">D. Heinemeier Hansson</option>
- # <option value="2">D. Thomas</option>

- InstanceTag.new(object, method, self, options.delete(:object)).to_collection_select_tag(collection, value_method, text_method, options, html_options)
- end
- # Returns <tt><select></tt>, <tt><optgroup></tt> and <tt><option></tt> tags for the collection of existing return values of

- # be selected. If calling +method+ returns +nil+, no selection is made without including <tt>:prompt</tt>
- # or <tt>:include_blank</tt> in the +options+ hash.
- #
- # Parameters:
- # * +object+ - The instance of the class to be used for the select tag
- # * +method+ - The attribute of +object+ corresponding to the select tag
- # * +collection+ - An array of objects representing the <tt><optgroup></tt> tags.
- # * +group_method+ - The name of a method which, when called on a member of +collection+, returns an
- # array of child objects representing the <tt><option></tt> tags.
- # * +group_label_method+ - The name of a method which, when called on a member of +collection+, returns a
- # string to be used as the +label+ attribute for its <tt><optgroup></tt> tag.
- # * +option_key_method+ - The name of a method which, when called on a child object of a member of
- # +collection+, returns a value to be used as the +value+ attribute for its <tt><option></tt> tag.
- # * +option_value_method+ - The name of a method which, when called on a child object of a member of
- # +collection+, returns a value to be used as the contents of its <tt><option></tt> tag.

- # Example object structure for use with this method:
- # class Continent < ActiveRecord::Base

- # # attribs: id, name
- # end
- # class Country < ActiveRecord::Base
- # belongs_to :continent
- # # attribs: id, name, continent_id
- # end
- # class City < ActiveRecord::Base
- # belongs_to :country
- # # attribs: id, name, country_id
- # end
- #
- # Sample usage:
- # grouped_collection_select(:city, :country_id, @continents, :countries, :name, :id, :name)
- #
- # Possible output:
- # <select name="city[country_id]">
- # <optgroup label="Africa">
- # <option value="1">South Africa</option>
- # <option value="3">Somalia</option>
- # </optgroup>

- end
- # Return select and option tags for the given object and method, using
- # #time_zone_options_for_select to generate the list of option tags.
- #
- # In addition to the <tt>:include_blank</tt> option documented above,
- # this method also supports a <tt>:model</tt> option, which defaults
- # to ActiveSupport::TimeZone. This may be used by users to specify a
- # different time zone model object. (See +time_zone_options_for_select+
- # for more information.)
- #
- # You can also supply an array of ActiveSupport::TimeZone objects
- # as +priority_zones+, so that they will be listed above the rest of the
- # (long) list. (You can use ActiveSupport::TimeZone.us_zones as a convenience
- # for obtaining a list of the US time zones, or a Regexp to select the zones
- # of your choice)
- #
- # Finally, this method supports a <tt>:default</tt> option, which selects
- # a default ActiveSupport::TimeZone if the object's time zone is +nil+.
- #
- # Examples:
- # time_zone_select( "user", "time_zone", nil, :include_blank => true)
- #
- # time_zone_select( "user", "time_zone", nil, :default => "Pacific Time (US & Canada)" )
- #
- # time_zone_select( "user", 'time_zone', ActiveSupport::TimeZone.us_zones, :default => "Pacific Time (US & Canada)")
- #
- # time_zone_select( "user", 'time_zone', [ ActiveSupport::TimeZone['Alaska'], ActiveSupport::TimeZone['Hawaii'] ])
- #
- # time_zone_select( "user", 'time_zone', /Australia/)
- #
- # time_zone_select( "user", "time_zone", ActiveSupport::Timezone.all.sort, :model => ActiveSupport::Timezone)
- def time_zone_select(object, method, priority_zones = nil, options = {}, html_options = {})

- end
- # Accepts a container (hash, array, enumerable, your type) and returns a string of option tags. Given a container
- # where the elements respond to first and last (such as a two-element array), the "lasts" serve as option values and
- # the "firsts" as option text. Hashes are turned into this form automatically, so the keys become "firsts" and values
- # become lasts. If +selected+ is specified, the matching "last" or element will get the selected option-tag. +selected+
- # may also be an array of values to be selected when using a multiple select.
- #
- # Examples (call, result):
- # options_for_select([["Dollar", "$"], ["Kroner", "DKK"]])
- # <option value="$">Dollar</option>\n<option value="DKK">Kroner</option>
- #
- # options_for_select([ "VISA", "MasterCard" ], "MasterCard")
- # <option>VISA</option>\n<option selected="selected">MasterCard</option>
- #
- # options_for_select({ "Basic" => "$20", "Plus" => "$40" }, "$40")
- # <option value="$20">Basic</option>\n<option value="$40" selected="selected">Plus</option>
- #
- # options_for_select([ "VISA", "MasterCard", "Discover" ], ["VISA", "Discover"])
- # <option selected="selected">VISA</option>\n<option>MasterCard</option>\n<option selected="selected">Discover</option>
- #
- # You can optionally provide html attributes as the last element of the array.
- #
- # Examples:
- # options_for_select([ "Denmark", ["USA", {:class=>'bold'}], "Sweden" ], ["USA", "Sweden"])
- # <option value="Denmark">Denmark</option>\n<option value="USA" class="bold" selected="selected">USA</option>\n<option value="Sweden" selected="selected">Sweden</option>
- #
- # options_for_select([["Dollar", "$", {:class=>"bold"}], ["Kroner", "DKK", {:onclick => "alert('HI');"}]])
- # <option value="$" class="bold">Dollar</option>\n<option value="DKK" onclick="alert('HI');">Kroner</option>
- #
- # If you wish to specify disabled option tags, set +selected+ to be a hash, with <tt>:disabled</tt> being either a value
- # or array of values to be disabled. In this case, you can use <tt>:selected</tt> to specify selected option tags.
- #
- # Examples:
- # options_for_select(["Free", "Basic", "Advanced", "Super Platinum"], :disabled => "Super Platinum")
- # <option value="Free">Free</option>\n<option value="Basic">Basic</option>\n<option value="Advanced">Advanced</option>\n<option value="Super Platinum" disabled="disabled">Super Platinum</option>

- # Be sure to specify the same class as the +value_method+ when specifying selected or disabled options.
- # Failure to do this will produce undesired results. Example:
