## Installation
The package can be installed as:
1. Add `triplex` to your list of dependencies in `mix.exs`:
```elixir
def deps do
[{:triplex, "~> 1.1.3"}]
end
```
2. Run in your shell:
```bash
mix deps.get
```
## Configuration
All you need to do in your project to start using it is to configure the Repo
you will use to execute the database commands with:
config :triplex, repo: ExampleApp.Repo
## Usage
Here is a quick overview of what you can do with triplex!
### Creating, renaming and droping tenants
To create a new tenant:
```elixir
Triplex.create("your_tenant")
```
PS.: this will run the migrations, so it's a function that takes a while to
complete depending on how much migrations you have.
If you change your mind and want to rename te tenant:
```elixir
Triplex.rename("your_tenant", "my_tenant")
```
PS.: we encourage you to use an unchangable thing as your tenant name, that
way you will not need to rename your tenant when changing the field.
And if you're sick of it and want to drop:
```elixir
Triplex.drop("my_tenant")
```
More information on `Triplex` module documentation.
### Creating tables inside tenant
To create a table inside your tenant you can use:
```bash
mix triplex.gen.migration your_migration_name
```
Also, you can move a normally generated migrations from inside
`priv/YOUR_REPO/migrations` to the `priv/YOUR_REPO/tenant_migrations`
folder.
The schemas look the same way, nothing to change.
To run the tenant migrations, just run:
```bash
mix triplex.migrate
```
This task will migrate all your existent tenants, one by one. If it
fail in any tenant, the next time you run it will continue from where
it stoped.
If you need more information, check the `Mix.Triplex` documentation, where
you can find the list of tasks and their descriptions.
### Querying, updating and inserting data inside tenants
To make queries, updates and inserts inside your tenant is quite easy.
Just send a `prefix` opt on your repo call with your current tenant name.
Like this:
```elixir
Repo.all(User, prefix: Triplex.to_prefix("my_tenant"))
```
It's a good idea to call `Triplex.to_prefix/1` on your tenant name, altough is
not required. Because, if you configured a `tenant_prefix`, this function will
return the prefixed one.
### Loading the current tenant to your `Plug.Conn`
We have some basic and configurable plugs you can use to load the current
tenant on your web app. Here is an example loading it from the subdomain:
```elixir
plug Triplex.SubdomainPlug, endpoint: MyApp.Endpoint
```
For more information, check the `Triplex.Plug` documentation for an overview of
our plugs.
