Getting Started on Elixir and Ecto Part 6

Updating Data

Updating records in Ecto requires us to first get a record from the database then create a changeset from that record and pass the new changes we want to make to that record, and finally, call the Ecto.Repo.update function.

	task = Taskers.Tasks |> Ecto.Query.first |> Taskers.Repo.one
	changeset = Taskers.Tasks.changeset(task, %{title: "Hello Reader"})
	Taskers.Repo.update(changeset)
	///Just like Taskers.Repo.insert, Taskers.Repo.update will return a
	///tuple and we can use the case statement to check for status
	case Taskers.Repo.update(changeset) do
	{:ok, task} ->
	# do something with task
	{:error, changeset} ->
	# do something with changeset
	end
