Ruby不正确的链接生成redirect_to products_path(@products)生成/products.1而不是/products/1

Question

我正试图在我的单一产品页面上添加一个评论。但是，当我单击Submit -它带我到/products.1页面，而不是/products/1

class CommentsController < ApplicationController
def create
    @product = Product.find(params[:product_id])
    @comment = @product.comments.new(comment_params)
    @comment.user = current_user
    @comment.save

    redirect_to products_path(@product)
end

def destroy

end

private
def comment_params
    params.require(:comment).permit(:user_id, :body, :rating)
end
end

和comment.html.erb

 <div class="row">
  <div class="col-sm-6">
    <% if signed_in? %>
      <h4>Add a review:</h4>
      <%= form_for([@product, @product.comments.build]) do |f| %>
        <p>
          <%= f.label :body, "Comment" %><br>
          <%= f.text_area :body, class: "form-control"  %>
        </p>
        <p>
          <%= f.label :rating %><br>
          <%= f.text_field :rating, class: "rating form-control" %>
        </p>  
        <p>
          <%= f.submit "Submit", class: "btn" %>
        </p>
      <% end %>
    <% end %>
  </div>
  </div>

Answer 1

尝试redirect_to @product而不是redirect_to products_path(@product)。

Answer 2

您检查了配置下的routes.rb吗？尝试在终端中运行rake路由，您可以从那里进行调试。
