Formtastic / rails表单未提交

Question

我正在尝试使用 formtastic 制作一个表格，在该表格中我可以输入一个 :opposition 选择一个 :venue 和一个 :team ，然后显示一个玩家列表，我可以勾选这些列表来为

我已经设置了表单，因此它可以正确呈现，但是在提交时它不会保存任何信息，只是重新加载页面。

我的代码在我的 github 上：https://github.com/jpknegtel/st_francis

型号

这涉及以下模型：

玩家

 has_many :player_fixtures
 has_many :fixtures, :through => :player_fixtures

夹具

 has_many :player_fixtures
 has_many :players, :through => :player_fixtures

PlayerFixture

belongs_to :player
belongs_to :fixture

控制器

def create
@fixture = Fixture.new(params[:fixture])
if @fixture.save
  flash[:notice] = "Fixture Created"
  redirect_to(:action =>'list')
else
  flash.now[:error] = "Could not save fixture. Please re-enter information"
  render('new')
end
end

def new
 @fixture = Fixture.new
end

表格

<%= semantic_form_for :fixture do |f| %>
 <%= f.inputs do %>
  <%= f.input :opposition  %>
  <%= f.input :team, :as => :select, :collection => Team.all %>
  <%= f.input :venue, :as => :check_boxes, :collection => Hash[Venue.all.map{|b| [b.name, b.id]}]%>
  <%= f.input :players, :as => :check_boxes, :collection => Hash[Player.all.map{|b| [b.full_name, b.id]}], :required => true  %>
<% end %>
<%= f.actions do %>
 <%=  f.action :submit, :as => :button %>
 <%=  f.action :cancel, :as => :link %>
<% end %>
<% end %>

因此，现在提交表单时，什么都没有传递。当查看网络砖服务器时，没有任何内容被提交，但页面只是被重新加载。

可以使用 rails 控制台插入记录。

编辑：我现在可以在提交时看到这个。

Answer 1

我的猜测是质量分配。您需要允许 rails 通过 massassignment 更新某些属性。

将此行添加到您的灯具模型中：

attr_accessible :players_attributes, :opposition, :team_id, :venue_id, :date

这允许 rails 通过new 和update_attributes 方法设置这些属性。
