Ruby on Rails 4 with Guacamole not find/load the adapter

[Aurélien Léger]

Hi,

I just started to watch and test ArangoDB and I wanted to start to use it with Ruby on Rails.

For that I make a new project on Rails 4 and see to use Guacamole.

But if I try to load the default page of Rails or use Rake, I have an error that the application not find or could not load the adapter.

I have the Guacamole gem and set my configuration in database.yml (with the same way on the Guacamole README).

Am I missing something? Have you an idea of what is the problem?

Thanks for reading.

Hey,

Sorry for the inconvenience, we will work on our documentation very soon. It really needs some work! :)

I think you gave the file the wrong name. It should be named ‘guacamole.yml’, not ‘database.yml’ :) Could you check that?

Best Wishes

Lucas

Hi,

yes, it should be `guacamole.yml`. While we're at it, would you prefer `database.yml`? For convenience reasons? The drawback would be, that you could not mix ArangoDB with a RDBMS. What do you think about this?

And thanks for getting started with Guacamole :-)

Best regards

Hi, thanks for your answers,

guacamole.yml is what I read and try but it didn't work too (but maybe because I rename database.yml?).

I will try one more time.

And actually I never had to work with multiple databases - type, so I don't really know for guacamole.yml or database.yml in this case.

So I test and it works.

It was - probably - because I rename my database.yml when I make my guacamole.yml and Rails could not find database.yml and it's normal.

When I test, I had an error with my configuration on guacamole.yml because I use dotenv.

I use the ENV['VAR'] to configure globale variables but it not work in guacamole:

`split': bad URI(is not URI?): <%= ENV['PROTOCOL'] %>://<%= ENV['HOST'] %>:<%= ENV['PORT'] %>/_db/<%= ENV['DATABASE'] %>/_api (URI::InvalidURIError)

I think Guacamole don't replace the variables by their values.

Thanks for your effort on this issue.

Yes, you need to deactivate ActiveRecord for this.

Currently you're right: We just take what was defined in `guacamole.yml`. We could of course add an ERB step before parsing the YAML. And it Rails seems to do the very same thing.

I created an issue for that: https://github.com/triAGENS/guacamole/issues/47

Unfortunately I don't have the time to deal with it right away. You have too options: don't use dotenv for now (it will not take longer than 2 weeks) or fix it by yourself ;-)

Anyway, thanks for the feedback, really helps us.

Regards
Dirk

Thanks for your answer and glad I could help.

For now I will test without dotenv to play a little with Guacamole and ArangoDB. :)
