Need some starter help with CouchPotato

ruby-talk

Hi All,

I am trying to use CouchPotato with a CouchDB instance on CloudAnt.

Following the very little documentation I could find, I am trying to do
this:

require "rubygems"
gem "couch_potato"
require "couch_potato"
CouchPotato::Config.database_name = "hangman"
CouchPotato::Config.database_server =
"https://user:password@orenshani.cloudant.com:5984"
CouchPotato.database

But I get an error

NoMethodError: undefined method `database_server=' for
#<#<Class:0xb73db280>:0xb73db0c8>
  from ./couch.rb:5
  from (irb):1:in `require'
  from (irb):1
  from /usr/lib/ruby/1.8/rubygems.rb:123

I checked with CouchPotato::Config.methods and database_server is really
not there

I am using CouchDB version 0.5.4

I'd appreciate it if anyone could tell me how to correctly connect to
the server. I can also be talked into other ways for using CouchDB as a
persistence layer...

Many thanks

Oren Shani

According to the README.md file here:

...you are supposed to use the database_name=() method to set the url:

CouchPotato::Config.database_name =
"http://username:password@example.com:5984/name_of_the_db&quot;

One trap which might catch you out - if the library itself has a file
called "couch.rb" then calling your own program "couch.rb" will prevent
'require' from loading it.

To eliminate that as a possible problem, just rename your couch.rb to
something else.

Oh well, then calling it isn't going to work :slight_smile: You'll need to dig
through the docs or find some sample apps which use CouchPotato.

Incidentally, I made a completely separate CouchDB API called
"couchtiny", although I'm not using or developing it at the moment. It's
on github, and you're more than welcome to try it out. It has some usage
examples in the README and in the doc/ subdir.

Thank you both for your answeres. Specifying the database URL to
database_name seem to work.

Candierb, I will look at your couchtiny and try to use it instead of
Couch Potato. Quite frankly, I'm just looking for a simple way to save
and load ruby objects with CouchDB, so whatever works...

Best,

Oren
