Cant access MongoLab Instances

[SeriousM]

Hi,

I try to access my MongoDB Instances with Genghis but without success :(

Used Versions:

• Genghis 2.1.6
• Mongo 1.7.1
• Ruby 1.9.3
• Rails 3.2.11

Used Connection Info (modified):

• test:test@ds045xx7.mongolab.com:45007
• test:test@ds045xx7.mongolab.com:45007/database_name

but everything works fine with my local instance.

Thanks for this cool gem :)!

I think this might be another instance of the same issue as #69 ... it looks like Genghis doesn't always deal well with non-admin user accounts, which most of the hosted services use.

I believe there are some fixes for it in develop. At the very least, it now surfaces more server error messages, so it'll be easier to debug. Do you mind installing v2.2.0-beta.1 and trying it out?

gem install genghisapp --pre

Thanks!

Thanks for the reply, here are my results:

• test:test@ds045xx7.mongolab.com:45007
• * Connection error: Failed to connect to a master node at ds045xx7.mongolab.com:45007
• test:test@ds045xx7.mongolab.com:45007/database_name
• * Connection error: Failed to connect to a master node at ds045xx7.mongolab.com:45007

And thats the log output during the session:

 /c$ ruby /c/Ruby193/lib/ruby/gems/1.9.1/gems/genghisapp-2.2.0.beta.1/genghis.rb

Does that helps you in any way?

That helps a ton. And wasn't what I was thinking at all.

I'll take a look :)

You're definitely running Genghis with v1.8 (or a dev release) of the mongo gem, since MongoClient didn't exist until then. You can verify this by dropping require 'mongo'; puts Mongo::VERSION in the first line of genghis.rb.

This, of course, raises two issues: (1) 10gen has a tendency to ship backwards compatibility breaks on point releases, and (2) I need to update Genghis to support v1.8 drivers :)

Do you mind checking out a local copy of the repo so you can use bundle exec to get the supported version of the gem? I get the feeling that this is not the error you were running into when you tried to connect to MongoLab before.

I was using your code (branch develop) locally but only got the same errors as before. .... because the port was blocked....

but ok, that was my fault. i switched to an independent machine and did the same. this time i was able to add the server to the list but only with the database name in the connection string like test:test@ds045xx7.mongolab.com:45007/database_name.
after switching into the server i get the error Database command 'listDatabases' failed: (errmsg: 'need to login'; ok: '0.0').

does that help you?

Check the just-released v2.3.0… It should fix all problems when authenticating against a single db.
