Rails – 如何接受JSON对象数组

如何在rails站点上接受一组JSON对象？ 我发布了类似的东西

{'team':{'name':'Titans'}} 

但是，如果我尝试发布带有对象数组的JSON。 它只保存第一个对象。

 {'team':[{'name':'Titans'},{'name':'Dragons'},{'name':'Falcons'}]} 

我的目标是在1个JSON文件中发送多个“团队”。 我在Rails方面要写什么？

在轨道方面，我有类似的东西

 def create @team = Team.new(params[:team]) @team.user_id = current_user.id respond_to do |format| if @team.save format.html { redirect_to(@team, :notice => 'Team was successfully created.') } format.json { render :json => @team, :status => :created, :location => @team } else format.html { render :action => "new" } format.json { render :json => @team.errors, :status => :unprocessable_entity } end end end 

我是否采取了参数：对于每个元素，创建一个新的团队或什么？ 我是ruby的新手，所以任何帮助都会受到赞赏。

我假设你发帖

 {'team':[{'name':'Titans'},{'name':'Dragons'},{'name':'Falcons'}]} 

然后你的参数将是

 "team" => {"0"=>{"chapter_name"=>"Titans"}, "1"=>{"chapter_name"=>"Dragons"}, "2"=>{"chapter_name"=>"Falcons"}} 

我的想法是

 def create #insert user id in all team params[:team].each_value { |team_attributes| team_attributes.store("user_id",current_user.id) } #create instance for all team teams = params[:team].collect {|key,team_attributes| Team.new(team_attributes) } all_team_valid = true teams.each_with_index do |team,index| unless team.valid? all_team_valid = false invalid_team = teams[index] end end if all_team_valid @teams = [] teams.each do |team| team.save @teams << team end format.html { redirect_to(@teams, :notice => 'Teams was successfully created.') } format.json { render :json => @teams, :status => :created, :location => @teams } else format.html { render :action => "new" } format.json { render :json => invalid_team.errors, :status => :unprocessable_entity } end end
