Fresher to arangoDB (to any object db)

[Vijay Bhargav]

Hi All,

I just installed ArangoDB. i have worked with relational databases so far where we connect to db from a language using a query and store the data in database. i would like to know how things work here. do we have any queries to execute or where can i get abc of this DB. please help as i am very much interested to learn ArangoDB with Ruby on rails

Many thanks

Vijay

Hi Vijay,

ArangoDB has an HTTP REST API, and all queries from the client-side (be
it a Ruby client or any different client) will send their requests to
the database via HTTP.

For example, if you started ArangoDB on host & port 127.0.0.1:8529, then
you can use your browser to connect to the database (the browser then is
a regular client of the HTTP API, too). Using the browser, you can do
some basic administration things, like creating/collections and
viewing/creating documents in them.

Note that there should also be a separate arangosh (ArangoShell) binary
that can be used for administration.

The entire REST API for ArangoDB 1.3 is described in detail here:
http://www.arangodb.org/manuals/current/ImplementorManual.html

This should clarify a lot in terms of what you can do with the database
in general.


Then there are client drivers for different programming languages, among
them there is a Ruby driver, Ashikawa.

It can be found here:
http://triagens.github.io/ashikawa-core/

I am actually not that much into Ruby myself, but if you should have any
specific questions regarding the Ruby driver or integration into a Rails
app, probably the driver maintainer (@moonbeamlabs) can help.

Best regards
Jan

Hi Vijay,

I'm the maintainer of the Ruby Driver :) So if you have any questions about it, just send me an email :)

Hi All,

I have installed ArangoDB in my PC windows 7 64 bit operating system. However I am not able to run the server. The following is what I am trying to do.

My task is to check if arangodb is properly connected and working file. That is to check db._collections(); for  result

Try1:

In command prompt I navigated to the path where arangoDB is installed.

I have tried

C:\triAgens>arangosh  --server.password “”

I got an error. FATEL module path not known…

I again tried

C:\triAgens> --server.endpoint tcp://127.0.0.1:8529 –server.username root

And password I specified Admin

I go t the same error.

Below is the screen shot.

 

Try2:

In command path, I have navigated to the path  where arangoDb is insalled and typed the following command

C:\triAgens> serverExample.bat

It has said that the server is ready for the business. Have ful! But I could not type any

Other command in the command prompt. I cudn`t see command prompt cursor blinking.

Here is the screen shot. I couldn`t figureout the error myself

Try3:

In the path where I have installed arangoDB, I have typed the following command

C:\triAgens> shellExample.bat

ArangoDB has started. But it said it couldn`t connect to endpoint. So I have tried to  the following command

Arangosh> --server.endpoint tcp://127.0.0.1:8529 –server.username root

I got the error again. Please see the below command prompt screen shot

 

Last try:

I tried to double click on the arangod application from folder where I installed the DB. I got the below error

The below screenshot , I tried different commands after executing shellexample.bat

Hi Vijay,

can you try the following:

cd \triAGENS
serverExample.bat

check the info message in the shell there should be a line

2013-08-24T19:51:43Z [4652] INFO ArangoDB (version 1.3.2 [WIN64-RELEASE]) is ready for business. Have fun!

at the end and a line

2013-08-24T19:51:32Z [4652] INFO using endpoint 'tcp://127.0.0.1:8529' for http non-encrypted requests

This is TRY 2 in your example. This will start the server.

Now either use Firefox (or IE) to open

  http://localhost:8529

or open another window and start

  shellExample.bat

this will a JavaScript shell and connect to the server.

cheers

Any ways can we create different databases if so can you please tell me how.

Many thanks

Hi Lucas,

Can you please give me a sample code to connect to ArangoDB using ruby. I would like to understand how things work in Ruby.

Many Thanks

Vijay

[Lucas Dohmen]

Hi Vijay,

No problem:

https://gist.github.com/anonymous/6351569

Clone it. Run `bundle` and then `bundle exec ruby arango.rb`.

Best Wishes,

Lucas

Thanks Lucas. I have understood the code. However, i was confused when i have created a new project in netbeans. there are lot of folders and i am not sure where i have to start writing

Many thanks 

Vijay

[Lucas Dohmen]

Hey Vijay,

Sorry, I can't help you with NetBeans at all – I never used it! I would suggest asking the question on StackOverflow.com or www.ruby-forum.com :)

Best Wishes,

Lucas
