Anyone know why my Template Haskell generated data constructors aren't being exported in Models.hs for use in Broken.hs?
Works.hs
Works.hs contains the first example listed in the Yeson Book.
Can be tested with
cabal run works
Broken.hs
Broken.hs moves the table declaration for persistent to Models.hs. Everything else should be the same, but it doesn't compile because it can't find missing data constructors.
Output from cabal build broken:
Preprocessing executable 'broken' for persistent-test-0.1.0.0...
