我有一个ajax表格:
_form.html.erb:
<%= form_for @innmelding, :remote => true, :html => { :id => 'kurs-form' } do |f| %>
innmeldings_controller.rb:
def create
@innmelding = Innmelding.new( params[:innmelding] )
flash[:notice] = "Lagret" if @innmelding.save
respond_with( @innmelding, :layout => !request.xhr? )
end
innmelding.rb:
class Innmelding < ActiveRecord::Base
belongs_to :laerer, :foreign_key => "ansvarlig"
belongs_to :laerer, :foreign_key => "overordnet"
has_many :kurss
validates_presence_of :dager_fra
end
的Gemfile:
source 'http://rubygems.org'
gem 'rails', '3.1.0.rc4'
gem 'sqlite3'
gem 'mysql2'
gem 'sass'
gem 'coffee-script'
gem 'coffeebeans'
gem 'uglifier'
gem 'jquery-rails'
gem 'devise'
gem 'cancan'
gem 'haml'
gem 'event-calendar', :require => 'event_calendar'
gem 'therubyracer'
当“dager_fra”字段为空时,我收到以下错误:
“错误NoMethodError:未定义的方法`bytesize'代表:dager_fra:符号”
我正在使用rails 3.1-rc4(rc1上的相同错误)和ruby 1.9.2。我怀疑它与ruby 1.9有关。还没有设法让它在ruby 1.8上运行,所以我还没有验证这一点(想想我读了一些字节化方法从某些版本的轨道移出的地方,因为它现在是Ruby 1.9的一部分)。
答案 0 :(得分:0)
这是rails问题,请查看此处https://github.com/rails/rails/issues/1730
尝试使用gemfile
gem'rails','3.1.0.rc4',: git =&gt; “https://github.com/rails/rails.git”,: branch =&gt; “3-1-稳定”
这帮助了我。
