Question

我正在尝试提交表单并收到此错误：Couldn't find Event without an ID

这是控制器：

def create
@event = Event.find(params[:event_id])
@event_sponsorship = EventSponsorship.new(params[:event_sponsorship])
@event_sponsorship.sponsor_id = current_user.id
@event_sponsorship.event_id = @event

respond_to do |format|
  if @event_sponsorship.save
    format.html { redirect_to @event_sponsorship, notice: 'Event sponsorship was successfully created.' }
    format.json { render json: @event_sponsorship, status: :created, location: @event_sponsorship }
  else
    format.html { render action: "new" }
    format.json { render json: @event_sponsorship.errors, status: :unprocessable_entity }
  end
end
end

以下是表格：

<%= simple_form_for(@event_sponsorship) do |f| %>
<%= f.error_notification %>

<div class="signin">
<%= f.hidden_field :event_id, value: @event %>

 <%= f.hidden_field :sponsor_id, value: current_user.id %>

<%= f.button :submit, :class => "btn btn-success btn-block", value: "Yes" %>
</div>
<% end %>

在create方法中，应从网址中找到event_id。我哪里错了？

Answer 1

发布您在服务器控制台中看到的错误，您会看到您的参数'event_id'是（我猜）'event_sponsorship'的子键

试试这个：

@event = Event.find(params[:event_sponsorship][:event_id])

甚至可能需要使用此代码：

@event = Event.find(params[:event_sponsorship].delete(:event_id))

这会从你的参数中移除'event_id'，并允许EventSponsorship.new无误地工作
