firstOrNew
method onHasManyThrough
relations. The other implementations of thefirstOrNew
method all take the unique attributes plus an array of values to be merged on the new instance. This wasn't the case with theHasManyThrough
relation. I noticed this as I was trying to identify the root cause on a bug in theupdateOrCreate
method. I've shared more context here.
