Plug.Assign

A simple plug to allow setting variables in a connection. For example, as a way to set default variables for a controller, view or template to use in a Phoenix app.

Installation

The package can be installed from Hex:

1. Add plug_assign to your list of dependencies in mix.exs:

```elixir
def deps do
  [{:plug_assign, "~> 1.0.0"}]
end
```

1. Fetch and install the dependencies

```sh
$ mix deps.get
```

1. Define assigns as part of your plug stack

```elixir
plug Plug.Assign, foo: "bar", bar: true, baz: 42
```

  Or Set variables for templates to use in a Phoenix Pipeline

```elixir
pipeline :admin do
  plug Plug.Assign, admin: true
end
```

  Or directly in a Phoenix Controller

```elixir
defmodule Blog.Admin.PostController do
  use Blog.Web, :Controller

  plug Plug.Assign, subsection: :posts
  plug Plug.Assign, %{read_request: true} when action in [:index, :show]
  ...
end
```
