Soft Delete Ecto Repo

The goal is to support soft delete functionality in Ecto.Repo. With the suggestion by @imranismail, another repo is created and the remaining functionalities are delegate to the original MyApp.Repo.

The new repo get/2 and all/1 functions will exclude the soft deleted record by default. delete/1 and delete_all/1 will update the delete_at column by default instead of deleting.

Example

MyApp.Repo.get(MyApp.User, 1) //will return nil if record is in soft delete state

That’s one of the real strengths of Docker: the ability to go back to a previous commit. The secret is simply to docker tag the image you want.

Here’s an example. In this example, I first installed ping, then committed, then installed curl, and committed that. Then I rolled back the image to contain only ping:

$ docker history imagename
IMAGE               CREATED             CREATED BY                SIZE
f770fc671f11        12 seconds ago      apt-get install -y curl   21.3 MB
