|

build_runner: ^2.0.0

```
|

`package:angel3_orm_generator` exports a class that you can include in a `package:build` flow:

# 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:
|
||||
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

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:

## 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.
