module Helpers
# Provides a number of methods for creating form tags that doesn't rely on an Active Record object assigned to the template like
# FormHelper does. Instead, you provide the names and values manually.
#
# NOTE: The HTML options <tt>disabled</tt>, <tt>readonly</tt>, and <tt>multiple</tt> can all be treated as booleans. So specifying
# <tt>:disabled => true</tt> will give <tt>disabled="disabled"</tt>.

mattr_accessor :embed_authenticity_token_in_remote_forms
self.embed_authenticity_token_in_remote_forms = true
# Starts a form tag that points the action to an url configured with <tt>url_for_options</tt> just like
# ActionController::Base#url_for. The method for the form defaults to POST.
#
# ==== Options
# * <tt>:multipart</tt> - If set to true, the enctype is set to "multipart/form-data".
# * <tt>:method</tt> - The method to use when submitting the form, usually either "get" or "post".
# If "put", "delete", or another verb is used, a hidden input with name <tt>_method</tt>
# is added to simulate the verb over post.
# * <tt>:authenticity_token</tt> - Authenticity token to use in the form. Use only if you need to
# pass custom authenticity token string, or to not add authenticity_token field at all
# (by passing <tt>false</tt>). Remote forms may omit the embedded authenticity token
# by setting <tt>config.action_view.embed_authenticity_token_in_remote_forms = false</tt>.
# This is helpful when you're fragment-caching the form. Remote forms get the
# authenticity from the <tt>meta</tt> tag, so embedding is unnecessary unless you
# support browsers without JavaScript.
# * A list of parameters to feed to the URL the form will be posted to.
# * <tt>:remote</tt> - If set to true, will allow the Unobtrusive JavaScript drivers to control the
# submit behavior. By default this behavior is an ajax submit.
#
# ==== Examples
# form_tag('/posts')
# # => <form action="/posts" method="post">
#
# form_tag('/posts/1', :method => :put)
# # => <form action="/posts/1" method="post"> ... <input name="_method" type="hidden" value="put" /> ...
#
# form_tag('/upload', :multipart => true)
# # => <form action="/upload" method="post" enctype="multipart/form-data">
#
# <%= form_tag('/posts') do -%>
# <div><%= submit_tag 'Save' %></div>
# <% end -%>
# # => <form action="/posts" method="post"><div><input type="submit" name="commit" value="Save" /></div></form>
#
# <%= form_tag('/posts', :remote => true) %>
# # => <form action="/posts" method="post" data-remote="true">
#
# form_tag('http://far.away.com/form', :authenticity_token => false)
# # form without authenticity token
#
# form_tag('http://far.away.com/form', :authenticity_token => "cf50faa3fe97702ca1ae")
# # form with custom authenticity token

# Creates a dropdown selection box, or if the <tt>:multiple</tt> option is set to true, a multiple
# choice selection box.
#
# Helpers::FormOptions can be used to create common select boxes such as countries, time zones, or
# associated records. <tt>option_tags</tt> is a string containing the option tags for the select box.
#
# ==== Options
# * <tt>:multiple</tt> - If set to true the selection will allow multiple choices.
# * <tt>:disabled</tt> - If set to true, the user will not be able to use this input.
# * <tt>:include_blank</tt> - If set to true, an empty option will be create
# * <tt>:prompt</tt> - Create a prompt option with blank value and the text asking user to select something
# * Any other key creates standard HTML attributes for the tag.
#
# ==== Examples
# select_tag "people", options_from_collection_for_select(@people, "id", "name")
