3 DEPRECATION WARNING: ActionView::SafeBuffer is deprecated! Use ActiveSupport::SafeBuffer instead. (called from local_constants at /home/mencio/.gem/ruby/1.8/gems/activesupport-2.3.8/lib/active_support/core_ext/module/introspection.rb:74)

代码发生地方是在 lib/fckeditor.rb:

  #  <%= javascript_include_tag :defaults, :fckeditor %>
  def javascript_include_tag(*sources)
    main_sources, application_source = [], []
    if sources.include?(:fckeditor)
      sources.delete(:fckeditor)
      sources.push('fckeditor/fckeditor')
    end
    unless sources.empty?
      main_sources = rails_javascript_include_tag(*sources).split("\n")
      application_source = main_sources.pop if main_sources.last.include?('application.js')
    end
    [main_sources.join("\n"), application_source].join("\n")
  end
end

需要把上面的代码都要注释掉 然后 页面的调用 fckeditor的方法也要修改

1
javascript_include_tag "fckeditor/fckeditor"

4 DEPRECATION WARNING: Giving :session_http_only to SessionStore is deprecated, please use :httponly instead.

错误发生的地方是： config/initializers/session_store.rb 代码如下：

ActionController::Base.session = {
:key         => '_src_session',
:session_http_only => true,
:secret      => '0f118033ca9bae289e520c98bbb1f68ef100bec29c7caf25baa7d9e7236876448a1d5c8d7ee384114125b2ae047fefb0d33729ae7476cc3b6b59b5f795d6908a'
}

修改为如下的代码：

ActionController::Base.session = {
:key         => '_src_session',
:httponly => true,
:secret      => '0f118033ca9bae289e520c98bbb1f68ef100bec29c7caf25baa7d9e7236876448a1d5c8d7ee384114125b2ae047fefb0d33729ae7476cc3b6b59b5f795d6908a'
