Rails / javascript：“参数键太多” – 什么是规范化表单数据的好方法？
我正在使用rails 3.1.3。 我有一个有很多领域的表格。 提交表单时，我收到此错误 ERROR RangeError: exceeded available parameter key space /home/james/.rvm/gems/ruby-1.9.3-p0/gems/rack-1.3.6/lib/rack/utils.rb:99:in `block in parse_nested_query’ /home/james/.rvm/gems/ruby-1.9.3-p0/gems/rack-1.3.6/lib/rack/utils.rb:93:in `each’ /home/james/.rvm/gems/ruby-1.9.3-p0/gems/rack-1.3.6/lib/rack/utils.rb:93:in `parse_nested_query’ /home/james/.rvm/gems/ruby-1.9.3-p0/gems/rack-1.3.6/lib/rack/request.rb:302:in `parse_query’ /home/james/.rvm/gems/ruby-1.9.3-p0/gems/rack-1.3.6/lib/rack/request.rb:190:in `POST’ /home/james/.rvm/gems/ruby-1.9.3-p0/gems/rack-1.3.6/lib/rack/methodoverride.rb:15:in `call’ /home/james/.rvm/gems/ruby-1.9.3-p0/gems/rack-1.3.6/lib/rack/runtime.rb:17:in `call’ /home/james/.rvm/gems/ruby-1.9.3-p0/gems/activesupport-3.1.3/lib/active_support/cache/strategy/local_cache.rb:72:in `call’ /home/james/.rvm/gems/ruby-1.9.3-p0/gems/rack-1.3.6/lib/rack/lock.rb:15:in `call’ /home/james/.rvm/gems/ruby-1.9.3-p0/gems/actionpack-3.1.3/lib/action_dispatch/middleware/static.rb:53:in `call’ /home/james/.rvm/gems/ruby-1.9.3-p0/gems/railties-3.1.3/lib/rails/engine.rb:456:in `call’ /home/james/.rvm/gems/ruby-1.9.3-p0/gems/rack-1.3.6/lib/rack/content_length.rb:14:in `call’ /home/james/.rvm/gems/ruby-1.9.3-p0/gems/railties-3.1.3/lib/rails/rack/debugger.rb:21:in `call’ /home/james/.rvm/gems/ruby-1.9.3-p0/gems/railties-3.1.3/lib/rails/rack/log_tailer.rb:14:in `call’ /home/james/.rvm/gems/ruby-1.9.3-p0/gems/rack-1.3.6/lib/rack/handler/webrick.rb:59:in `service’ /home/james/.rvm/rubies/ruby-1.9.3-p0/lib/ruby/1.9.1/webrick/httpserver.rb:138:in `service’ /home/james/.rvm/rubies/ruby-1.9.3-p0/lib/ruby/1.9.1/webrick/httpserver.rb:94:in `run’ /home/james/.rvm/rubies/ruby-1.9.3-p0/lib/ruby/1.9.1/webrick/server.rb:191:in `block in start_thread’ 显然，提交的k / v对太多了。 什么是解决这个问题的好方法？ […]
