module BootstrapForm
  module ActionViewExtensions
    # This module creates BootstrapForm wrappers around the default form_with
    # and form_for methods
    #
    # Example:
    #
    #   bootstrap_form_for @user do |f|
    #     f.text_field :name
    #   end
    #
    # Example:
    #
    #   bootstrap_form_with model: @user do |f|
    #     f.text_field :name
    #   end
