ruby-on-rails - rails 上的 ruby : form_for doesn't redirect

Question

我的 form_for 没有重定向到我指定的操作。我真的不知道问题出在哪里。

我的查看详情:

<!-- Comments Form -->
    <div class="well">
      <h4>Comment:</h4>
      <form class="comment-form">
        <div class="form-group">
          <%= form_for(:comments, :url => {:action => 'post_comment'}) do |f| %>
              <%= f.text_area(:content, :rows => "3", :class => "form-control new-comment") %>
              <%= f.hidden_field :book_id, :value => @comments[:book_id] %>
              <%= f.hidden_field :user_id, :value => session[:user_id] %>
              <%= submit_tag("Send") %>
          <% end %>
        </div>
      </form>
    </div>

我的 Controller :

def detailedbook
    @book = Book.find(params[:id])
    @comments = Comments.new
    @rating = Rates.new(:book_id => params[:id], :user_id => session[:user_id])
    @previouscomments = Comments.where(:book_id => params[:id] )
  end
def post_comment
    @comments = Comments.new(params.require(:comments).permit(:content, :book_id, :user_id))
    @comments.book_id = params[:id]
    if @comments.save
      redirect_to(:action => 'showbooks')
    else
      redirect_to(:action => 'home')
    end
  end

提交似乎甚至没有发生。我做错了什么？

我认为您指定的 url 无法正常工作。假设 Comments 是您的 Controller 名称:

<%= form_for(:comments, :url => post_comment_comments_url, :method=> "POST" ) do |f| %>

这应该适合你。
