rails_create_differences

Testing differences in rails create methods.

The model unit tests fail on the appropriate code. The following code snippet can be run from the rails console to show the problem.

# Creating a root node
root = Category.create(full_name: 'root')

# Creating first child node, should have root first root as the parent
# This works as expected
foo = Category.create(full_name: 'root/foo')

# Creating another child node, should have root first root as the parent
# This doesn't work as expected, it seems to "inherit" the ActiveRecord::Relation
bar = Category.where(full_name: 'root/bar').create

When running the above from the console it shows the SQL output. The problematic line seems to be inheriting the ActiveReocrd::Relation and running something like:

# Runs this (basically)
Category.where(first_name: 'root/bar').where(first_name: 'root').first_or_create

# Instead of this
Category.where(first_name: 'root').first_or_create

This prior where clause is what was originally passed in to create bar.
