Ruby on rails 从单选按钮向模型中输入信息并返回值

以下是视图的代码：

  <h3>Reviews:</h3>
<% @restaurant.reviews.reverse.each do |review| %>
posted by: <%= review.poster %><br />
written: <%= time_ago_in_words(review.created_at) %> ago<br />
Review: <%= review.rating %><br />
<%= review.article %><br /><br />
<% end %>

<hr />
<h3>Submit new review:</h3>
<%= form_tag :action => 'review', :id => @restaurant do %>
<h4>Poster: </h4>
<%= text_field "review", "poster" %>
<h4>Rating:</h4>
<%= radio_button_tag(:rating, "1") %>
<%= label_tag(:rating_1, "1") %>
<%= radio_button_tag(:rating, "2") %>
<%= label_tag(:rating_2, "2") %>
<%= radio_button_tag(:rating, "3") %>
<%= label_tag(:rating_3, "3") %>
<%= radio_button_tag(:rating, "4") %>
<%= label_tag(:rating_4, "4") %>
<%= radio_button_tag(:rating, "5") %>
<%= label_tag(:rating_5, "5") %>

<!--<strong>Date: </strong><%= datetime_select "review", "date" %><br /><br />-->
<h4>Review:</h4><br />
<%= text_area "review", "article", :rows => 5 %><br />
<%= submit_tag "Review" %>
<% end %>

因此，我将单选按钮更改为

除了

之外，您可以发布

提交表单时生成的
日志吗？我想如果我可以将评分添加到审核哈希中，那么应该可以让它工作了。但我不太清楚该怎么做。
  def review
    @restaurant.reviews << Review.create!(review_params)
    redirect_to :action => "show", :id => params[:id]
  end

  def review_params
    params.require(:review).permit(:poster, :rating, :article)
  end
