I am little confused on how these changes fixes that issue. I can see that you have abstracted this inline logic https://github.com/adonisjs/lucid/pull/1037/files#diff-76f631b7273d470789eccc7dbf79045349516bc0178df8de8dfa4425d2be1dd4R233-R234 to its own function. But how does that fixes the issue.

PS: I have not scanned the entire source code yet, so maybe I am missing something :)

@thetutlage The whereIn method uses transformValue that converts Chainable using following logic:

if (value instanceof Chainable) {
      value.applyWhere()
      return value.knexQuery
    }

So there is applyConstraints() missing for relationships. I've added a toKnex method to Chainable which calls applyWhere and returns knexQuery. I override this method in relation query builder (like other methods do), so that toKnex also calls applyConstraints.

Okay, let me give it a run locally to ensure nothing else breaks.
