我正在学习将 padrino 与 haml 一起使用,并且在使用远程表单时遇到了这种奇怪的行为。用于创建元素的部分就像一个魅力,但更新后使用的部分以明文形式呈现。我确定这是一个菜鸟错误,但我似乎找不到它。
#user.rb
get :show, :with => :id do
@user = User.get(params[:id].to_i) #REWRITE
@posts = @user.posts
session[:user_id] = @user.id
render 'user/show'
end
#post.rb
put :update, :with => :id, :provides => :js do
@post = post.first(:id => params[:post][:id].to_i, :user_id => session[:user_id].to_i)
@post.attributes(:name => params[:post][:name], :up => params[:post][:up],
:down => params[:post][:down])
if @post.save
render 'post/update'
end
end
#show.haml
#show
.user
.title= link_to @user.login, url_for(:user, :show, :id => @user.id)
.date= time_ago_in_words(@user.created || Time.now) + ' ago'
.password= @user.password
#posts= partial 'post/list', :locals => { :posts => @user.posts }
#_post.haml
.post{:id => "post#{post.id}"}
.name= post.name
.date= time_ago_in_words(post.created || Time.now) + ' ago'
- if post.up
.up +
- if post.down
.down -
= link_to "(x)", url(:post, :destroy, :id => post.id, :format => :js, :method => 'delete'), :confirm => "Sure?", :remote => true
= link_to "(e)", url(:post, :edit, :id => post.id, :format => :js), :remote => true
#_edit.haml
- form_for :post, url(:post, :update, :id => @post.id, :format => :js), :remote => true, :method => 'put', :id => 'post_edit_form' do |f|
= partial 'post/form', :locals => {:f => f}
= f.text_field :id, :hidden => true
= f.submit "Edit", :class => 'button'
#update.js.haml
:plain
alert("ok");
单击编辑按钮后,我得到一个白页: alert("ok"); 为什么 update.js.haml 页面没有呈现为远程 js?
