|
|
Create the storage for the given repository.
|
|
|
|
The repositories to create are the ones specified under the
|
|
`:ecto_repos` option in the current app configuration. However,
|
|
if the `-r` option is given, it replaces the `:ecto_repos` config.
|
|
|
|
Since Ecto tasks can only be executed once, if you need to create
|
|
multiple repositories, set `:ecto_repos` accordingly or pass the `-r`
|
|
flag multiple times.
|
|
|
|
## Examples
|
|
|
|
$ mix ecto.create
|
|
$ mix ecto.create -r Custom.Repo
|
|
|
|
## Command line options
|
|
|
|
* `-r`, `--repo` - the repo to create
|
|
* `--quiet` - do not log output
|
|
* `--no-compile` - do not compile before creating
|
|
* `--no-deps-check` - do not compile before creating
