> Provides simple, sane and terse shortcuts for Ecto models.
Ecto.Rut is a wrapper around `Ecto.Repo` methods that usually require you to pass
the module as the subject and sometimes even require you do extra work before hand,
(as in the case of `Repo.insert/3`) to perform operations on your database. Ecto.Rut
tries to reduce code repetition by following the "Convention over Configuration"
ideology.
See the [Ecto.Rut Documentation][docs] on HexDocs.
## Basic Usage
You can call normal `Ecto.Repo` methods directly on the Models:
```elixir
Post.all
# instead of YourApp.Repo.all(Post)
Post.get(2)
# instead of YourApp.Repo.get(Post, 2)
Post.insert(title: "Awesome Post", slug: "awesome-post", category_id: 3)
# instead of:
# changeset = Post.changeset(%Post{}, %{title: "Awesome Post", slug: "awesome-post", category_id: 3})
# YourApp.Repo.insert(changeset)
```
See the [Repo Coverage Section][github-coverage] or the [Hex Documentation][docs] for a full list of supported methods.
## Installation
Add `:ecto_rut` as a dependency in your mix.exs file:
```elixir
defp deps do
[{:ecto_rut, "~> 1.2.2"}]
end
```
and run:
```bash
$ mix deps.get
```
### Phoenix Projects
If you have an app built in [Phoenix Framework][phoenix], just add `use Ecto.Rut`
in the `models` method in `web/web.ex` or anywhere else you have defined your
basic Schema structure:
```elixir
# web/web.ex
def model do
quote do
use Ecto.Schema
use Ecto.Rut, repo: YourApp.Repo
# Other stuff...
end
end
```
That's it! `Ecto.Rut` will automatically be loaded in all of your models. If you don't
have a central macro defined for your Schema, take a look at this example:
[**Repo.Schema**][repo-schema-eg].
### Other Ecto Projects
If you're not using Phoenix or you don't want to use Ecto.Rut with all of your models (why wouldn't
you!?), you'll have to manually add `use Ecto.Rut`:
```elixir
defmodule YourApp.Post do
use Ecto.Schema
use Ecto.Rut, repo: YourApp.Repo
# Schema, Changeset and other stuff...
end
```
## Configuration
You do not need to configure Ecto.Rut unless your app is set up differently. All values are
inferred automatically and it should just work, but if you absolutely have to, you can specify
the `repo` and `model` modules:
```elixir
defmodule YourApp.Post do
use Ecto.Schema
use Ecto.Rut, model: YourApp.Other.Post, repo: YourApp.Repo
end
```
See the [Configuration Section][docs-config] in HexDocs for more details.
## Not for Complex Queries
`Ecto.Rut` has been designed for simple use cases. It's not meant for advanced queries and
operations on your Database. Ecto.Rut is supposed to do only simple tasks such as getting,
updating or deleting records. For any complex queries, you should use the original `Ecto.Repo`
methods.
You shouldn't also let Ecto.Rut handicap you; Ideally, you should understand how Ecto.Repo
lets you do advanced queries and how Ecto.Rut places some limits on you (for example, not
being able to specify custom options). José has also [shown his concern][jose-concern]:
> My concern with using something such as shortcuts is that people will forget those
> basic tenets schemas and repositories were built on.
That being said, Ecto.Rut's goal is to save time (and keystrokes) by following the convention
over configuration ideology. You shouldn't need to call `YourApp.Repo` for every little task,
or involve yourself with changesets everytime when you've already defined them in your model.
## Methods
### [All][fun-all]
```elixir
iex> Post.all
[%Post{id: 1, title: "Post 1"},
%Post{id: 2, title: "Post 2"},
%Post{id: 3, title: "Post 3"}]
```
### [Get][fun-get]
```elixir
iex> Post.get(2).title
"Blog Post No. 2"
```
Also see [`get!/1`][fun-get!]
### [Get By][fun-get_by]
```elixir
Post.get_by(published_date: "2014-10-22")
```
Also see [`get_by!/1`][fun-get_by!]
### [Insert][fun-insert]
You can insert Changesets, Structs, Keyword Lists or Maps. When Structs, Keyword Lists or
Maps are given, they'll be first converted into a changeset (as defined by your model) and
validated before inserting.
So you don't need to create a changeset every time before inserting a new record.
```elixir
# Accepts Keyword Lists
Post.insert(title: "Introduction to Elixir")
# Accepts Maps
Post.insert(%{title: "Building your first Phoenix app"})
# Even accepts Structs (these would also be validated by your defined changeset)
Post.insert(%Post{title: "Concurrency in Elixir", categories: ["programming", "elixir"]})
```
Also see [`insert!/1`][fun-insert!]
### [Update][fun-update]
There are two variations of the update method; [`update/1`][fun-update] and
[`update/2`][fun-update2]. For the first, you can either pass a changeset (which would be
inserted immediately) or a modified struct (which would first be converted into a changeset
by comparing it with the existing record):
```elixir
post = Post.get(2)
modified_post = %{ post | title: "New Post Title" }
Post.update(modified_post)
```
The second method is to pass the original record as the subject and a Keyword List (or a Map)
of the new attributes. This method is recommended:
```elixir
post = Post.get(2)
Post.update(post, title: "New Post Title")
```
Also see [`update!/1`][fun-update!] and [`update!/2`][fun-update2!]
### [Delete][fun-delete]
```elixir
post = Post.get_by(id: 9)
Post.delete(post)
```
Also see [`delete!/1`][fun-delete!]
### [Delete All][fun-delete_all]
```elixir
Post.delete_all
```

## Roadmap
- [x] Write Tests
- [x] Write Documentation
- [ ] Cover all main `Ecto.Repo` methods
- [x] Allow explicitly passing Application and Repo modules to the `use Ecto.Rut` statement
- [ ] Add support for preloading with existing methods
- [ ] Introduce new wrapper and helper methods that do not exist in Ecto, such as:
- [ ] `Model.count`
- [ ] `Model.first` and `Model.last`
- [ ] `Model.find_or_create(obj)`
- [ ] Methods that accept direct arguments (E.g. `delete_by_id(3)`)
