CareersController#create for rails 4 中的 ActionController::UnknownFormat

Question

我正在尝试在提交表单时为弹出的“成功消息”添加 js 文件。 它说，ActionController::UnknownFormat in CareersController#create

在我的控制器中：

   def create
    @career = Career.new(career_params)

    respond_to do |format|
      if @career.save
        format.js {render :template => 'careers/create', :locals => { :career => @career}  }
      else
        format.html { render :new, :locals => { :career => @career} }
      end
    end
  end

还有我的 create.js.erb 文件：

$(document).ready(function(){

    $("#new_career").submit(function(e){
        var postData = $(this).serializeArray();
        var formURL = $(this).attr("action");
        $.ajax(
                {
                    url : formURL,
                    type: "POST",
                    data : postData,
                    format: 'js',
        success:function(data, textStatus, jqXHR)
        {
            alert("Form has been submitted");
        },
        error: function(jqXHR, textStatus, errorThrown){
            alert("Network connection problem");
        }
    });
    e.preventDefault(); //STOP default action
    e.unbind(); //unbind. to stop multiple form submit.
});

})

这是我的服务器错误日志：

我做错了什么？请帮忙

CareersController#create 中的 ActionController::UnknownFormat

您已将格式定义为 json 而不是 js。改成这样

def create
    @career = Career.new(career_params)

    respond_to do |format|
      if @career.save
        format.js {render :template => 'careers/create', :locals => { :career => @career}  }
      else
        format.html { render :new, :locals => { :career => @career} }
      end
    end
  end

更新

您还应该在 ajax

中定义 format as js

#create.js.erb
$(document).ready(function(){

    $("#new_career").submit(function(e){
        var postData = $(this).serializeArray();
        var formURL = $(this).attr("action");
        $.ajax(
            {
                url : formURL,
                type: "POST",
                data : postData,
                format: 'js', #here
                success:function(data, textStatus, jqXHR)
                {
                    alert("Form has been submitted");
                },
                error: function(jqXHR, textStatus, errorThrown){
                    alert("Network connection problem");
                }
            });
        e.preventDefault(); //STOP default action
        e.unbind(); //unbind. to stop multiple form submit.
    });

})
