RethinkDB: Get last N from an object

RethinkDB: Get last N from an object

fixed the issue. Will look into that further If you want the last n, I would write obj.coerceTo('array').slice(-n).coerceTo('object'). (Objects in RethinkDB implicitly sort their fields by the key.) If you want the first n, I'd write .slice(0, n) instead of .slice(-n).

I wish did fix the issue. You can combine two queries by writing something like r.expr([query1, query2]) and it should work.

it should still fix some issue I'm new to rethinkdb and I wanted to filter something like... get all with Kiwi or Strawberry as preferred fruit , This is what you're looking for:
code :
  .filter((row) => { 
    r.or( // Returns true if any of the following are true
  .filter((row) => {
    return row('fruits')('preferred').setIntersection(['Kiwi', 'Strawberry']).count().gt(0)

rethinkdb changesfeed in express with socket.io displaying [object object]

To fix this issue I'm using express.js, rethinkdb, thinky, socket.io. Trying to notify the index page of any changes that happens in the db. So I use rethinkdb changesfeed (and I can see the updates in console.log) but the cursor/feed is showing object object instead of the data. , From your code:
code :
//if (item && item.new_val)
socket.emit("message-from-server", { greeting: item });
Why can't I append an object to an array in rethinkdb?

hope this fix your issue You need to update document with a document not an array. Your reql should look like this
code :
    milestones: rethink.row('milestones').append({
      dateAchieved: "2017-01-01",
      phaseType: "TEST"
