Rails開發過程中碰到過的問題

1. DEPRECATION WARNING: config.action_view.debug_rjs will be removed in 3.1, from 3.1 onwards you will need to install prototype-rails to continue to use RJS templates . (called from <top (required)> at /Users/me/projects/my_app/config/environment.rb:5)

解決方案:

The warning is being caused by your config file. Look for a line like config.action_view.debug_rjs = true in {app_root}/config/environments/development.rb or production.rb and [color=red]comment it out[/color]. If you're not using rjs views anyway then you won't miss the debugging in development mode anyway (and it's off by default in production)

2. DEPRECATION WARNING: <% %> style block helpers are deprecated. Please use <%= %>.

解決:

Rails 3.0.9 prints warning in log for spree_static_content/app/views/admin/pages/edit.html.erb.

I think problem in following code:

It should change the line

<% semantic_form_for([:admin, @page]) do |f| -%> 
           

to

<%= semantic_form_for([:admin, @page]) do |f| -%>
