Simple question: I know how to access a data field in a hash by doing hash_name[datafield_name]. But what if the datafield itself is a hash? I tried a couple of variations but nothing seems to be working and tutorials do not go into such details. Is there a simple way or should I create separate instances? -Chris -- Posted via http://www.ruby-forum.com/.

Originally posted on github, reported to the right place. I would like to open a discussion about how `to_json` and `as_json` operates in Rails from a performance standpoint.

Our use case presents the challenge in sending out potentially large JSON (or XML, but we''ll focus on JSON rendering here)

Hi, I am looking for a way in which I can check if rows in 1 dataframe are present in another data frame in a unique way. A row in dataframe should be super set of any row in another dataframe. I can write a for loop for it, however, that will be inefficient. So, I am looking for an efficient way to do this in R. I have explained it with an example below: I want to check if a row in dataframe
