Sheetshow.Table.Change (Sheetshow v0.1.0)

Copy Markdown View Source

One thing to do to a table: a value, made by Sheetshow.Table.insert/2, Sheetshow.Table.update/2, Sheetshow.Table.delete/2 or Sheetshow.Table.restore/1.

A change names a row by id, never by where it sits. That is what makes Sheetshow.Table.refresh/2 worth having: when the rows have shifted under you, the changes you are holding are still the right changes, and planning them again against fresh positions costs nothing and asks Google nothing.

iex> alias Sheetshow.Table
iex> Table.update("a", %{cost: "1100.00"}).action
:update
iex> Table.delete("a", hard: true).hard
true

record is only the columns the change names. An update writes those and leaves every other cell on the row alone, which is also what keeps a column somebody else was editing out of harm's way.
