Question

I have been working on implementing the Ancestry gem in my rails app, I have almost got it working the way I want it to.

I am having problems with the following line of code from the Ancestry README docs.

TreeNode.find_by_name('Crunchy').subtree.arrange

The code that I am using in my app is as follows:

Message.find_by_name('FedEx')[e-mail]

With this, I am getting an error message:

syntax error, unexpected tIVAR
...find_by_name('FedEx')[e-mail] );@output_buffer.saf...
...

Can anyone tell me what I am doing wrong, or explain to me what TreeNode and subtree should be replaced with?

Answer 1

I belive what you want is: Message.find_by_name('FedEx').subtree.arrange.
Message class should implement ancestry via has_ancestry according to the README.
