+DynamicForm
+===========
+
+DynamicForm holds a few helpers method to help you deal with your models, they are:
+
+* input(record, method, options = {})
+* form(record, options = {})
+* error_message_on(object, method, options={})
+* error_messages_for(record, options={})
+
+It also adds f.error_messages and f.error_messages_on to your form builders.

+ # The Active Record Helper makes it easier to create forms for records kept in instance variables. The most far-reaching is the +form+
+ # method that creates a complete form for all the basic content types of the record (not associations or aggregations, though). This
+ # is a great way of making the record quickly available for editing, but likely to prove lackluster for a complicated real-world form.
+ # In that case, it's better to use the +input+ method and the specialized +form+ methods in link:classes/ActionView/Helpers/FormHelper.html
+ module DynamicForm
+ # Returns a default input tag for the type of object returned by the method. For example, if <tt>@post</tt>
+ # has an attribute +title+ mapped to a +VARCHAR+ column that holds "Hello World":
+ #
+ # input("post", "title")
+ # # => <input id="post_title" name="post[title]" size="30" type="text" value="Hello World" />
+ def input(record_name, method, options = {})
+ InstanceTag.new(record_name, method, self).to_tag(options)
+ end
+
+ # Returns an entire form with all needed input tags for a specified Active Record object. For example, if <tt>@post</tt>
+ # has attributes named +title+ of type +VARCHAR+ and +body+ of type +TEXT+ then
+ #
+ # form("post")
+ #
+ # would yield a form like the following (modulus formatting):
+ #
+ # <form action='/posts/create' method='post'>
+ # <p>
+ # <label for="post_title">Title</label><br />
+ # <input id="post_title" name="post[title]" size="30" type="text" value="Hello World" />
+ # </p>
+ # <p>
+ # <label for="post_body">Body</label><br />
+ # <textarea cols="40" id="post_body" name="post[body]" rows="20"></textarea>
+ # </p>
+ # <input name="commit" type="submit" value="Create" />
+ # </form>
+ #
+ # It's possible to specialize the form builder by using a different action name and by supplying another
+ # block renderer. For example, if <tt>@entry</tt> has an attribute +message+ of type +VARCHAR+ then
+ #
+ # form("entry",
+ # :action => "sign",
+ # :input_block => Proc.new { |record, column|
+ # "#{column.human_name}: #{input(record, column.name)}<br />"
+ # })
+ #
+ # would yield a form like the following (modulus formatting):
+ #
+ # <form action="/entries/sign" method="post">
+ # Message:
+ # <input id="entry_message" name="entry[message]" size="30" type="text" /><br />
+ # <input name="commit" type="submit" value="Sign" />
+ # </form>
+ #
+ # It's also possible to add additional content to the form by giving it a block, such as:
+ #
+ # form("entry", :action => "sign") do |form|
+ # form << content_tag("b", "Department")
+ # form << collection_select("department", "id", @departments, "id", "name")
+ # end
+ #
+ # The following options are available:
+ #
+ # * <tt>:action</tt> - The action used when submitting the form (default: +create+ if a new record, otherwise +update+).
+ # * <tt>:input_block</tt> - Specialize the output using a different block, see above.
+ # * <tt>:method</tt> - The method used when submitting the form (default: +post+).
+ # * <tt>:multipart</tt> - Whether to change the enctype of the form to "multipart/form-data", used when uploading a file (default: +false+).
+ # * <tt>:submit_value</tt> - The text of the submit button (default: "Create" if a new record, otherwise "Update").

+ # * <tt>:header_tag</tt> - Used for the header of the error div (default: "h2").
+ # * <tt>:id</tt> - The id of the error div (default: "errorExplanation").
+ # * <tt>:class</tt> - The class of the error div (default: "errorExplanation").
+ # * <tt>:object</tt> - The object (or array of objects) for which to display errors,
+ # if you need to escape the instance variable convention.
+ # * <tt>:object_name</tt> - The object name to use in the header, or any text that you prefer.
+ # If <tt>:object_name</tt> is not set, the name of the first object will be used.
+ # * <tt>:header_message</tt> - The message in the header of the error div. Pass +nil+
+ # or an empty string to avoid the header message altogether. (Default: "X errors
+ # prohibited this object from being saved").
+ # * <tt>:message</tt> - The explanation message after the header message and before
+ # the error list. Pass +nil+ or an empty string to avoid the explanation message
+ # altogether. (Default: "There were problems with the following fields:").
+ #
+ # To specify the display for one object, you simply provide its name as a parameter.
+ # For example, for the <tt>@user</tt> model:
+ #
+ # error_messages_for 'user'
+ #
+ # You can also supply an object:
+ #
+ # error_messages_for @user
+ #
+ # This will use the last part of the model name in the presentation. For instance, if
+ # this is a MyKlass::User object, this will use "user" as the name in the String. This
+ # is taken from MyKlass::User.model_name.human, which can be overridden.
+ #
+ # To specify more than one object, you simply list them; optionally, you can add an extra <tt>:object_name</tt> parameter, which
+ # will be the name used in the header message:
+ #
+ # error_messages_for 'user_common', 'user', :object_name => 'user'
+ #
+ # You can also use a number of objects, which will have the same naming semantics
+ # as a single object.
+ #
+ # error_messages_for @user, @post
+ #
+ # If the objects cannot be located as instance variables, you can add an extra <tt>:object</tt> parameter which gives the actual
+ # object (or array of objects to use):
+ #
+ # error_messages_for 'user', :object => @question.user
+ #
+ # NOTE: This is a pre-packaged presentation of the errors with embedded strings and a certain HTML structure. If what
+ # you need is significantly different from the default presentation, it makes plenty of sense to access the <tt>object.errors</tt>
+ # instance yourself and set it up. View the source of this method to see how easy it is.
