@emgee3 How can I get to the data? API is not very clear to me. I hope to give me a look,If you have a small case, I hope you...

@emgee3 I still don't understand, this can only be written in the server?

@emgee3 I'm not quite understand,how should I add code to insert into a collection

@emgee3 I put it in the method, but there is still a mistake, how to change this? very grateful.
