The preview feature serves both accounts and stock vouchers (SI/PI/PE + DN/PR/SE) and its show_*_preview entry points live in controllers/stock_controller, so the cohesive GL+SLE preview module belongs in controllers/, not stock/services/. Pure move + import-path update; GL and stock previews stay together (shared get_columns/ get_data formatters; read-side, kept out of the write-path services). Verified: ledger snapshots green; module resolves at new path.

"""Read-side GL / Stock Ledger preview helpers.
|
|
|
|
A dry-run consumer of the posting path, shared across accounts and stock vouchers
|
|
(Sales/Purchase Invoice, Payment Entry, Delivery Note, Purchase Receipt, Stock
|
|
Entry): it submits-in-memory, reads the resulting GL/SLE entries and formats them
|
|
for the datatable preview, then rolls back. Lives separately from the posting
|
|
services it orchestrates. The whitelisted ``show_*_preview`` entry points stay on
|
|
``stock_controller`` (their dotted path is referenced from client JS).
