Rails3 dynamic_form插件无法识别? [英] Rails3 dynamic_form plugin not recognized?
问题描述
使用Ruby 1.9.2和Rails 3-
尝试使用<%= error_messages_for 'story' %>时出现此错误:
DEPRECATION WARNING: error_messages_for was removed from Rails and is now available as a plugin. Please install it with `rails plugin install git://github.com/rails/dynamic_form.git`. (called from _app_views_stories_new_html_erb__1042605186_33967248__100840187 at C:/Ruby192/shovell/app/views/stories/new.html.erb:1)
所以我按照它说的做了，然后运行了插件安装.但是，现在我在vendor/plugins处有一个空的dynamic_form文件夹.我没有运气就尝试使用http而不是git.我还在网址末尾添加了/，该名称可用于其他在线用户，但没有运气.
我将gem dynamic_form添加到Gemfile，将require "dynamic_form"添加到application.rb，然后重新运行bundle install.它表明dynamic_form-1.1.3已安装到`lib/ruby/gems/1.9.1/gems/'，但我仍然遇到相同的错误.
解决方案正如Jeremy指出的那样，只需在github上下载rails/dynamic_form并将其解压缩到vendor/plugins并重命名文件夹"dynamic_form"即可.之前它对我不起作用的原因是，因为我使用的是动态格式的其他人的修改版，当然也没有指定它.
Using Ruby 1.9.2 and Rails 3 -
When attempting to use <%= error_messages_for 'story' %> I get this error:
DEPRECATION WARNING: error_messages_for was removed from Rails and is now available as a plugin. Please install it with `rails plugin install git://github.com/rails/dynamic_form.git`. (called from _app_views_stories_new_html_erb__1042605186_33967248__100840187 at C:/Ruby192/shovell/app/views/stories/new.html.erb:1)
So I did what it said and ran the plugin install. However now I have an empty dynamic_form folder at vendor/plugins. I tried using http instead of git with no luck. I also added a / at the end of the URL which worked for someone else online, but with no luck.
I added gem dynamic_form to the Gemfile and require "dynamic_form" to the application.rb as well as rerun bundle install. It shows that dynamic_form-1.1.3 is installed to `lib/ruby/gems/1.9.1/gems/' but I am still getting the same error.
The solution was as Jeremy pointed out, to simply download rails/dynamic_form on github and extract it to vendor/plugins and rename the folder "dynamic_form". The reason it didn't work for me before was because I was using someone else's modified version of dynamic form and of course not specifying it.
