The relation ran after the block ended

A Rails app uses the acts_as_tenant gem, so every request runs with a current tenant and tenant-scoped models filter by it. I was building a super-admin dashboard that shows rows from every tenant. Rows from other tenants came out with a blank organization and no View button.

My first try put the whole request inside ActsAsTenant.without_tenant with an around_action. That broke the layout, which uses the current tenant’s name:

ActionView::Template::Error: undefined method `name' for nil

So I wrapped only the lookups in the controller:

without_tenant do
  @rows = Row.where(id: ids).includes(parent: :organization)
end

The totals on the page were right after that, but the rows were still blank. @rows is a lazy relation. Building it inside the block doesn’t run it. It ran in the view, when the template first called each, and by then the block had ended and the tenant was back. The preload of the tenant-scoped parent records ran with the tenant filter on, so every parent from another tenant came back nil.

Loading the relation inside the block fixed it:

without_tenant do
  @rows = Row.where(id: ids).includes(parent: :organization).to_a
end

.load works too. Any relation that has to run outside the current tenant needs to load before the block ends, so it’s worth checking the other instance variables the view reads.
