Ruby on rails JSON呈现：如何包含开头括号描述？

我有一些Ruby代码输出JSON，如下所示：

def nearby
  #@bathrooms = Bathroom.geo_scope(:origin =>[params[:lat],[params[:lon]]], :within => 5)
  lat = params[:lat]
  lon = params[:lon]
  #@bathrooms = Bathroom.geo_scope(:within => 5, :origin => [45.580639,-122.677682], :order=>'distance')
  @bathrooms = Bathroom.geo_scope(:within => 3, :origin => [lat,lon], :order=>'distance')
  respond_to do |format|
    format.json  { render :json => @bathrooms }
    format.js   { render :nothing => true } 
  end   
end

 [{"ID":129,"access":"1","avail":"0","bathroomtype":"0","city":"PORTLAND","comment":"","country":"US","created":"0000-00-00 00:00:00","directions":"The two bathrooms are in the long hallway at the back of the restaurant, past the bar.","distance":"2.94986114636676","lat":"45.539217","lon":"-122.661795","modifed":"0000-00-00","name":"Echo","postal":"97212-3727","slug":"echo-portland170","source":"","state":"OR","street":"2225 NE Martin Luther King Jr. Blvd"},

结果是这样的：

def nearby
  #@bathrooms = Bathroom.geo_scope(:origin =>[params[:lat],[params[:lon]]], :within => 5)
  lat = params[:lat]
  lon = params[:lon]
  #@bathrooms = Bathroom.geo_scope(:within => 5, :origin => [45.580639,-122.677682], :order=>'distance')
  @bathrooms = Bathroom.geo_scope(:within => 3, :origin => [lat,lon], :order=>'distance')
  respond_to do |format|
    format.json  { render :json => @bathrooms }
    format.js   { render :nothing => true } 
  end   
end

 [{"ID":129,"access":"1","avail":"0","bathroomtype":"0","city":"PORTLAND","comment":"","country":"US","created":"0000-00-00 00:00:00","directions":"The two bathrooms are in the long hallway at the back of the restaurant, past the bar.","distance":"2.94986114636676","lat":"45.539217","lon":"-122.661795","modifed":"0000-00-00","name":"Echo","postal":"97212-3727","slug":"echo-portland170","source":"","state":"OR","street":"2225 NE Martin Luther King Jr. Blvd"},

我不知道该怎么做的是给这一组命名？例如，在第一个括号之后，我想命名这套浴室。如何在Rails中执行此操作？

请尝试：

render json: { bathrooms: @bathrooms }

尝试：

看起来@bathrooms是一个列表，所以不能为列表中的元素指定键。你需要先做张地图。例如，如果只需要第一个元素：

format.json { render :json => {:bathrooms => @bathrooms[0]} }

要设置所有列表元素，请执行以下操作：

format.json { render :json => {:bathrooms => @bathrooms} }

不行：我尝试了：呈现json:{bathrooms:@bathrooms}，它看起来不像有效的ruby语法。请看我的答案，这是一个完美的Ruby 1.9.2语法。。。如果你更喜欢Ruby 1.9.2，请使用好的hashrockets，直到Ruby 1.9.2变得更像Javascript：）是的，Ruby这样更轻，我喜欢它，除了当它涉及到

foo:：bar

时，它看起来很奇怪，但没有做到这一点：我尝试过：呈现json:{bathrooms:@bathrooms}它看起来不像有效的Ruby语法。请看我的答案，这是一个完美的Ruby 1.9.2语法。。。如果你更喜欢Ruby 1.9.2，请使用旧的hashrockets，直到Ruby 1.9.2变得更像Javascript：）没错，Ruby这样更轻，我喜欢它，除了当它涉及到

时，它看起来很奇怪，看起来更好，因为括号现在把它命名为浴室。但是，如何指定列表中的所有元素？这不仅仅是第一个记录？另一个老派科技的胜利：）这看起来更好，因为括号现在命名为浴室。但是，如何指定列表中的所有元素？这不仅仅是第一个记录？另一个老派科技的胜利：）
