## Usage
# Usage
You'll need these dependencies in your `pubspec.yaml`:
```yaml
dependencies:
angel3_orm: ^4.0.0-beta.1
angel3_orm: ^4.0.0
dev_dependencies:
angel3_orm_generator: ^4.0.0-beta.1
angel3_orm_generator: ^4.0.0
build_runner: ^2.0.0
```
`package:angel3_orm_generator` exports a class that you can include in a `package:build` flow:
* `PostgresOrmGenerator` - Fueled by `package:source_gen`; include this within a `SharedPartBuilder`.
- `PostgresOrmGenerator` - Fueled by `package:source_gen`; include this within a `SharedPartBuilder`.
However, it also includes a `build.yaml` that builds ORM files automatically, so you shouldn't
have to do any configuration at all.

simply just not extend `Model`:

String get username;

# Relations
## Relations
`angel3_orm` supports the following relationships:
* `@HasOne()` (one-to-one)
* `@HasMany()` (one-to-many)
* `@BelongsTo()` (one-to-one)
* `@ManyToMany()` (many-to-many, using a "pivot" table)
- `@HasOne()` (one-to-one)
- `@HasMany()` (one-to-many)
- `@BelongsTo()` (one-to-one)
- `@ManyToMany()` (many-to-many, using a "pivot" table)
The annotations can be abbreviated with the default options (ex. `@hasOne`), or supplied
with custom parameters (ex. `@HasOne(foreignKey: 'foreign_id')`).

```
The relationships will "just work" out-of-the-box, following any operation. For example,
after fetching an `Author` from the database in the above example, the `books` field would
be populated with a set of deserialized `Book` objects, also fetched from the database.

Relationships use joins when possible, but in the case of `@HasMany()`, two queries are used:
* One to fetch the object itself
* One to fetch a list of related objects
## Many to Many Relations
A many-to-many relationship can now be modeled like so.
`RoleUser` in this case is a pivot table joining `User` and `Role`.
- One to fetch the object itself
- One to fetch a list of related objects
### Many to Many Relations
A many-to-many relationship can now be modeled like so. `RoleUser` in this case is a pivot table joining `User` and `Role`.
Note that in this case, the models must reference the private classes (`_User`, etc.), because the canonical versions (`User`, etc.) are not-yet-generated:

```
TLDR:
1. Make a pivot table, C, between two tables, table A and B
2. C should `@belongsTo` both A and B. C *should not* extend `Model`.
3. A should have a field: `@ManyToMany(_C) List<_B> get b;`
4. B should have a field: `@ManyToMany(_C) List<_A> get a;`

## Columns
# Columns
Use a `@Column()` annotation to change how a given field is handled within the ORM.
## Column Types
### Column Types
Using the `@Column()` annotation, it is possible to explicitly declare the data type of any given field:

## Indices
### Indices
Columns can also have an `index`:

```
## Default Values
### Default Values
It is also possible to specify the default value of a field.
**Note that this only works with primitive objects.**
If a default value is supplied, the `SqlMigrationBuilder` will include
it in the generated schema. The `PostgresOrmGenerator` ignores default values;
it does not need them to function properly.
