ruby-on-rails - 如何使用 link_to 将固定参数数据传递给现有表单而不是提交表单？

Question

现在我有一个像这样的表单视图

<%=form_for(([@community, @comment]), :remote => true, :class => 'form' ) do |f| %>
    <%= f.text_field :body, :id => "body", :class => "chat" %> 
    <button type="submit" class="btn">submit</button>
<% end %>

<% @comments.each do |comment| %>
    Request to <%= request(@community, comment.user) %> <br />
<% end %>

然后rake routes显示这个

POST   /communities/:community_id/comments(.:format)     comments#create

application_helper是这样编码的。我不知道在create_community_comment_path(????????)正确的道路上放什么。

def request(community, user)
    if user
        nickname = user.profile.try(:nickname) 
        body = "You've got a request from " + nickname
        link_to "<span class='btn'>request</span>".html_safe , create_community_comment_path(community, body),{:method => :post}
    end
end

谁能告诉我如何link_to将固定参数传递给表单？

Answer 1

尝试这个

link_to "<span class='btn'>request</span>".html_safe , create_community_comment_path(community, body, :parm1=>"Valu1", :parm2=>"Valu2"),{:method => :post}
