Rails渲染页面为json

Question

How to render page as json correctly

my chunk of code

respond_to :html, :xml, :json


  def getOffersByURL
   @my_model= Mymodel.where(attr1: params[:url], :validFrom => {:$lte => Time.now}).all
   respond_with @my_model
  end

When in trying to do like this nothing happens

http://0.0.0.0:3000/getOffersByURL?url=some_data.xml 

or

http://0.0.0.0:3000/getOffersByURL?url=some_data.json

concretely it comes like this

Processing by MyController#getOffersByURL as HTML
  Parameters: {"url"=>"some_data.xml"}

Try to change your function:

def getOffersByURL
  @my_model= Mymodel.where(attr1: params[:url], :validFrom => {:$lte => Time.now}).all
  respond_to do |format|
    format.json {
        render json: @my_model
    }
    format.html {
        @my_model
    }
    end
end

What happens if you try to show your json like this in your view:

<%= @my_model.to_json %>

Do you have any data checking the page in the browser? Open the developers tool and try to find if the object brings any data...
