如何转换此response_to选项以使用Rails 3版本? [英] How to convert this respond_to options to use Rails 3 version?

问题描述

respond_to do |format|
  if @user.save
    format.js { render :nothing => true, :status => :ok, :location => @user }
  else
    format.js { render :json => @user.errors, :status => :unprocessable_entity }
  end
end

我尝试过的所有选项(例如将respond_to :js放在控制器的顶部等)都无法像这种方式那样起作用.

All options I've tried (like putting respond_to :js at the top of controller, etc) don't quite work the way as in this.

推荐答案

Rails 3格式:

Rails 3 Format:

使用 respond_to :json和 respond_with (@ user)

Use respond_to :json and respond_with(@user)

  respond_to :json  # You can also add  , :html, :xml  etc.

  def create
    @user= User.new(params[:user])
      #---For html flash
      #if @user.save
      #  flash[:notice] = "Successfully created user."
      #end
    respond_with(@user)
  end

# Also, add :remote => :true, :format => :json to the form.
