我尝试在Rails 4的应用程序中使用Ajax。要将我的js发送到客户端,请使用:
respond_to do |format| format.js end
在我的控制器中。但这是我的控制器生成的错误“ ActionController :: UnknownFormat”。有人可以帮我吗?
main_controller.rb:
class Oweb::MainController < ApplicationController def index ..... end def setmagasinstatus begin @mag = Magasin.find(params[:id]) if @mag.etatmagasin.lib == 'Ouvert' @mag.etatmagasin = Etatmagasin.where(lib: 'Fermé').first else @mag.etatmagasin = Etatmagasin.where(lib: 'Ouvert').first end rescue ActiveRecord::RecordNotFound logger.error("Attempt to access invalid Magasin #{params[:id]}") redirect_to_index("Invalid Magasin") else @mag.save @mags = Magasin.where(user_id: current_user.id) respond_to do |format| format.js end end end end
setmagasinstatus.js.erb:
page.replace_html("bloc_magasin", :partial => "listmagasins", :object => @mags)
layouts / application.html.slim:

抓住:
您的控制台日志显示:
由Oweb :: MainController#setmagasinstatus处理 为HTML
在您的控制器操作中,您不支持HTML响应。因此,您将面临的错误UnknownFormat。
UnknownFormat
解:
添加format: "js"您的ajax调用。例如:
format: "js"
$.ajax url: "/oweb/main/setmagasinstatus", data: 'id=' + id, format: 'js'
