Rails -如何接受JSON对象数组
Rails -如何接受JSON对象数组
提问于 2011-10-13 18:49:11
如何在我的rails站点上接受JSON对象数组？我发布了类似这样的内容
{'team':{'name':'Titans'}}但是，如果我试图发布一个包含对象数组的JSON。它只保存第一个对象。
{'team':[{'name':'Titans'},{'name':'Dragons'},{'name':'Falcons'}]}我的目标是在一个JSON文件中发送多个‘团队’。在Rails端我应该写些什么？
在rails方面，我有一些类似的东西
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我是否需要参数:并为每个元素创建一个新的团队或其他什么？我刚接触ruby，所以如果有任何帮助，我将不胜感激。

让我假设你发布了
{'team':[{'name':'Titans'},{'name':'Dragons'},{'name':'Falcons'}]}那么你的助手将会是
"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
