In case anyone else in the future is reading this, I had the exact same problem when I was deploying NodeBB to AWS using the Ubuntu 14.04 LTS AMI.

I had installed the latest version Redis by compiling from source (see tutorial here: https://www.digitalocean.com/community/tutorials/how-to-install-and-use-redis) but I had forgotten to uninstall the default redis-server package that came along with Ubuntu. After uninstalling the default redis-server package, the error message went away.

sudo apt-get --purge autoremove redis-server

Thanks @julian.

I was able to set the picture by extending the OAuth.login method (https://github.com/julianlam/nodebb-plugin-sso-oauth/blob/master/library.js#L160-L213).

function _getAvatar(data) {
  ...
}

...
var success = function (uid) {
  // Save provider-specific information to the user
  User.setUserField(uid, constants.name + 'Id', payload.oAuthid);
  db.setObjectField(constants.name + 'Id:uid', payload.oAuthid, uid);

  var avatar = _getAvatar(payload.data);
  if (avatar) {
    User.setUserField(uid, 'picture', avatar);
    User.setUserField(uid, 'uploadedpicture', avatar);
  }
  ...

I'm not sure why but just updating the picture didn't seem to work. I had to update uploadedpicture as well.

The other thing I needed to do was change the settings. Turns out that user:*:settings isn't fully populated until I visit the settings page and click on "save settings". So what I ended up having to do was:

var mySettings = {};   // Custom settings.
User.saveSettings(uid, mySettings, function (err) {});

and that seemed to work.

I'm trying to write a Python API wrapper over the NodeBB REST API but I'm a little confused by the interface. I understand that you can add /api to most if not all urls and be able to get json response.

"https://community.nodebb.org/user/truetuna"
"https://community.nodebb.org/api/user/truetuna"

However, I'd prefer to reference a resource by their id rather than the associated username, topic name, category name etc.

For example,

# My username vs my uid.
"https://community.nodebb.org/api/user/truetuna"
"https://community.nodebb.org/api/user/6166"

I ask because it seems like there's quite a split between the read-api and the write-api provided by the nodebb-plugin-write-api plugin. For example, if I wanted to PUT to a user, I have to reference the resource via the uid, but when I want to GET a user, I need to use their username.

It's not too bad when it's the user resource but it gets pretty weird when it comes to say, topics. With topics, I need the tid AND the topic title. In addition, the topic title needs to be formatted in a specific way (removing commas, lowercase, replacing spaces with hyphens etc.).

# The original title was "Deleted topics, comments"
"https://community.nodebb.org/api/topic/6438/deleted-topics-comments"
"https://community.nodebb.org/api/topic/6438/"

It's very confusing and it makes it quite difficult to use the API.

Am I missing something? Is it possible to reference resources just by their id? Is there a switch I need to turn on in the ACP for this to work? Is there a piece of documentation I'm missing?

Because ideally, I'd prefer to only have to use the id as the resource reference, e.g.

PUT, DELETE "https://community.nodebb.org/api/topic/6438/"
PUT, DELETE "https://community.nodebb.org/api/user/6438/"
PUT, DELETE "https://community.nodebb.org/api/category/6438/"
...

Thanks

PS. I'm using NodeBB v0.7.3

I might be missing something but does NodeBB do something extra to timestamps? I'm trying to convert the "lastonline" timestamp to a datetime:

~/w/nodebb ❯❯❯ redis-cli
127.0.0.1:6379> HGETALL user:1
...
13) "lastonline"
14) "1447135877476"
...

but I end up getting something like the above.

If I remove the last 3 digits, I get something a bit closer to the real time.

Time is hard . Can anyone explain what's going on?
