(NoMethodError) error when including LiquidPlanner gem in Redmine

Added by Diya John over 13 years ago

I am working on developing a Redmine plugin to update tasks / projects in Liquidplanner. I am using the liquidplanner gem. When I include this gem in the redmine plugin, I get the following error

rubygems.rb:223:in `activate': You have a nil object when you didn't expect it! (NoMethodError)
You might have expected an instance of Array.
The error occurred while evaluating nil.map
from rubygems.rb:249:in `activate'
from rubygems/custom_require.rb:35:in `require'
.....
from redmine/config/environment.rb:20
from rubygems/custom_require.rb:31:in `gem_original_require'
from redmine/vendor/rails/railties/lib/commands/server.rb:84
from rubygems/custom_require.rb:31:in `gem_original_require'
from script/server:3

I am using
Ruby -> 1.8.7
Redmine -> 1.0.1
rubygems -> 1.3.7
on windows

Here is what I did.. I added a plugin in Redmine (just one hook file inside lib folder ) modified the init.rb file inside the plugin to include the hook file

In the hook file added the following code

require 'rubygems'
require 'liquidplanner' *--> including this line causes the error*
lp = LiquidPlanner::Base.new(:email=>'my_email', :password=>'my_password')
workspace = lp.workspaces(my_space_id)

The gem works when I execute it independently.
Any idea why this is happening?

Thanks for your time!

Can you post the whole error stack? This looks like a bug of either rubygems not including the gem correctly or the gem not responding correctly to this inclusion though...

This is what I get

The following ruby script works when executed separately
require 'rubygems'
require 'liquidplanner'
lp = LiquidPlanner::Base.new(:email=>'my_email', :password=>'my_password')
workspace = lp.workspaces(my_space_id)
puts workspace

So I guess the gem not responding correctly to this inclusion.....

Mmh, maybe you could drop by the IRC channel and ask edavis10, or maybe even meineerde, I think they have a little more insight in those matters and they might be able to help you.
