db.getSortedSetRange is not a function

[fidelix]

Sorry to bother you again, this is probably something small, and likely my fault.

Here's the simple file I created:

var async = require('async');
var Data = require('../nodebb-plugin-import/server/data.js');
Data.eachPost(console.log,
  function (err) {
    if (err) {
      throw err;
    }
    console.log("DONE!!");
  }
);

When I run it I get this error:

/home/fidelix/www/anbient/forum/node_modules/nodebb-plugin-import/server/data.js:476
                db.getSortedSetRange(setKey, start, end, function(err, ids) {
                   ^

Process finished with exit code 1

Any ideas why it's not defined? Looking at the db object it seems to have the proper configs (mongodb, localhost, etc)...

i think I know why, i will fix it tomorrow

hey, I found the issue, but it's NOT** (edit) an easy fix, the thing is that you're trying to use the database before it had some time to load - there is a callback to db.init() but the issue with this one is if you're already running NodeBB at the same-time, the callback would never execute. I have a fix in mind, but it's Easter! so I am give you a very stupid workaround till i fix this the right way, hopefully next week.

timeout way

var async = require('async');
var Data = require('../nodebb-plugin-import/server/data.js');

// just wrap it in a timeout till it's ready.
setTimeout(function() {

  Data.eachPost(console.log,
    function (err) {
      if (err) {
        throw err;
      }
      console.log("DONE!!");
    }
  );

}, 3000); // 3 seconds worked for me, you might need more depending on how large your db-index is.

interval way

var async = require('async');
var Data = require('../nodebb-plugin-import/server/data.js');

var go = function () {
  Data.eachPost(console.log,
    function (err) {
      if (err) {
        throw err;
      }
      console.log("DONE!!");
    }
  );
};
// you can test it every 500ms 
var interval = setInterval(function() {
  if (Data.db.client) {
    clearInterval(interval);
    go();
  }
}, 500);

Both solutions are very stupid, but if you're writing a one-off script, they should work

Thank you so much @akhoury. This worked!

Ops... let me leave it open...
