Query inside of ActiveRecord Observer generated incorrect SQL
Reported by cilcoder | May 17th, 2010 @ 11:33 PM
The Problem
For a model class, 'NodeArgument', I am calling NodeArgument.all inside of an observer for the NodeArgument model and instead of returning all NodeArguments, it is only returning a subset of them.
The Setup:
Model Classes:
Node
has_many :node_arguments
Node Arguments
belongs_to :node
An Observer with after_correct.
Triggering the issue
I have a Node object and call
@node.node_arguments.find_or_create_by_name(...)
This successfully creates the Node Argument and triggers the
observer's after_create method.
Result
In the observer I am using NodeArgument.all. From the log, I can see that they query being generated has a where clause of node_id = .
Expected Result
I would expect the NodeArgument.all method to behave like normal. It seems to be a reentrancy problem to me.
