module Helpers
# Provides a number of methods for turning different kinds of containers into a set of option tags.
#
# The collection_select, select and time_zone_select methods take an options parameter, a hash:
#
# * :include_blank - 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.
#
# select("post", "category", Post::CATEGORIES, {include_blank: true})
#
# could become:
#
#
#
# Another common case is a select tag for a belongs_to-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:
#
#
#
# * :prompt - 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.
#
# select("post", "person_id", Person.all.collect {|p| [ p.name, p.id ] }, {prompt: 'Select Person'})
#
# could become:
#
#
#
# Like the other form helpers, +select+ can accept an :index 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.
#
# select("album[]", "genre", %w[rap rock country], {}, { index: nil })
#
# becomes:
#
#
#
# * :disabled - can be a single value or an array of values that will be disabled options in the final output.
#
# select("post", "category", Post::CATEGORIES, {disabled: 'restricted'})
#
# could become:
#
#
#
# When used with the collection_select helper, :disabled can also be a Proc that identifies those options that should be disabled.
#
# 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 archived? is called, this would return:
#
#
module FormOptionsHelper
# ERB::Util can mask some helpers like textilize. Make sure to include them.
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.
#
# There are two possible formats for the +choices+ parameter, corresponding to other helpers' output:
#
# * A flat collection (see +options_for_select+).
#
# * A nested collection (see +grouped_options_for_select+).
#
# For example:
#
# select("post", "person_id", Person.all.collect {|p| [ p.name, p.id ] }, { include_blank: true })
#
# would become:
#
#
#
# assuming the associated person has ID 1.
#
# 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, post.person_id is the selected option. Specify selected: value to use a different selection
# or selected: nil to leave all options unselected. Similarly, you can specify values to be disabled in the option
# tags by specifying the :disabled option. This can either be a single value or an array of values to be disabled.
#
# A block can be passed to +select+ to customize how the options tags will be rendered. This
# is useful when the options tag has complex attributes.
#
# select(report, "campaign_ids") do
# available_campaigns.each do |c|
# content_tag(:option, c.name, value: c.id, data: { tags: c.tags.to_json })
# end
# end
#
# ==== Gotcha
#
# The HTML specification says when +multiple+ parameter passed to select and all options got deselected
# web browsers do not send any value to server. Unfortunately this introduces a gotcha:
# if an +User+ model has many +roles+ and have +role_ids+ accessor, and in the form that edits roles of the user
# the user deselects all roles from +role_ids+ multiple select box, no +role_ids+ parameter is sent. So,
# any mass-assignment idiom like
#
# @user.update(params[:user])
#
# wouldn't update roles.
#
# To prevent this the helper generates an auxiliary hidden field before
# every multiple select. The hidden field has the same name as multiple select and blank value.
#
# This way, the client either sends only the hidden field (representing
# the deselected multiple select box), or both fields. Since the HTML specification
# says key/value pairs have to be sent in the same order they appear in the
# form, and parameters extraction gets the last occurrence of any repeated
# key in the query string, that works for ordinary forms.
#
# In case if you don't want the helper to generate this hidden field you can specify
# include_hidden: false option.
#

# Returns and tags for the collection of existing return values of

# be selected. If calling +method+ returns +nil+, no selection is made without including :prompt
# or :include_blank in the +options+ hash.
#
# The :value_method and :text_method parameters are methods to be called on each member
# of +collection+. The return values are used as the +value+ attribute and contents of each
# tag, respectively. They can also be any object that responds to +call+, such
# as a +proc+, that will be called for each member of the +collection+ to
# retrieve the value/text.

# Example object structure for use with this method:

# belongs_to :author
# end
#
# class Author < ActiveRecord::Base
# has_many :posts

# Sample usage (selecting the associated Author for an instance of Post, @post):

# If @post.author_id is already 1, this would return:

#
# 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 tags.
# * +group_method+ - The name of a method which, when called on a member of +collection+, returns an

# * +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 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 tag.
# * +option_value_method+ - The name of a method which, when called on a child object of a member of

# for more information.)
#
