使用link_to传递对象以在表单中创建操作

我想换掉:

   <%= button_tag "Create" , :class => "round" %>

  <%= link_to trips_path(@trip),  :class => "round", :method => :post do %>
    <div id="createtrip_button_newtrip">
      Create
    </div>
  <% end %>

形式

<%= form_for @trip, :html =>{ :multipart => true} do |f| %>


  <div class="field">
    <%= f.label :name %><br/>
    <%= f.text_field :name  %>
  </div>
  <div id="description_container_newtrip">
    <%= f.label :description %><br/>
    <%= f.text_area :description %>
  </div>
  <div class="field">
    <%= f.label :location %><br/>
    <%= f.text_field :location %>
  </div>

  <div class="field">
    <%= f.label :start_date, "Start Date:" %><br/>
    <%= f.date_select :start_date, :order => [:month, :day, :year]   %>
  </div>
  <div class="field">
    <%= f.label :end_date, "End Date:" %><br/>
    <%= f.date_select :end_date, :order => [:month, :day, :year] %>
  </div>
  <div class="field">
    <%= f.hidden_field :user_id %>
  </div>
  <div class="field">
    <%= f.hidden_field :traveldeal_id %>
  </div>

  <%= #button_tag "Create", :class => "round" %>


  <%= link_to trips_path(@trip),  :class => "round", :method => :post do %>
    <div id="createtrip_button_newtrip">
      Create
    </div>
  <% end %>

<% end %>

link_to在正确的控制器中调用正确的操作,但我的表单没有保存。这是方法:

  def create
    @trip = Trip.new(params[:trip])
    if @trip.save
      redirect_to root_path
    else
      redirect_to login_path
    end
  end

我一直被重定向到login_path。我认为我的问题是我没有将@trip的参数发送给控制器。

任何提示?

以下是我的开发日志中的params哈希:

我认为问题是您的link_to不会影响表单。您可以使用一些javascript解决此问题:

$(".submit_link").click(function(){
  var link = $(this);
  var form = link.closest("form");
  form.submit();
  return false;
});

然后将课程submit_link添加到您的链接中。

如果您不想使用javascript,请使用submit_tag,并使用CSS设置样式。有关走这条路线的一些提示,请参见此处:http://cssbutton.com/forms/
