# AutoDbSet

Automagically add `DbSet`s to your `DbContext`

## Usage

Place `[AutoDbSet]` attribute on the database models you want to register...

```cs

using AutoDbSetGenerators;

namespace AutoDbSet.Demo;

[AutoDbSet]

public class Person

{

    public required string Name { get; set; }

    public required DateOnly Birthday { get; set; }

    public required float Height { get; set; }

}

```

Place `[AutoDbContext]` attribute on your `DbContext` and make it `partial`...

```cs

using AutoDbSetGenerators;

using Microsoft.EntityFrameworkCore;

namespace AutoDbSet.Demo;

[AutoDbContext]

public partial class MyCoolDbContext : DbContext

{

}

```

And watch the magic happen!

```cs

namespace AutoDbSet.Demo;

[global::System.Runtime.CompilerServices.CompilerGeneratedAttribute]

[global::System.Diagnostics.CodeAnalysis.ExcludeFromCodeCoverage]

[global::System.CodeDom.Compiler.GeneratedCode("AutoDbSet", "1.0.0.0")]

public partial class MyCoolDbContext

{

    public required Microsoft.EntityFrameworkCore.DbSet Persons { get; init; }

}

```

## DbSet naming

By default `AutoDbSet` will try to naively pluralize the names ([here's how](./AutoDbSet/NameHelpers.cs)). It does not,

therefore, work with verbs that have irregular plural form, nor does it work with non-English languages.

You can, however, give the sets your own, custom name:

```cs

[AutoDbSetGenerators.AutoDbSet(Name = "People")]

public class Person

{

    public required string Name { get; set; }

    public required DateOnly Birthday { get; set; }

    public required float Height { get; set; }

}

```

will generate

```cs

namespace AutoDbSet.Demo;

[global::System.Runtime.CompilerServices.CompilerGeneratedAttribute]

[global::System.Diagnostics.CodeAnalysis.ExcludeFromCodeCoverage]

[global::System.CodeDom.Compiler.GeneratedCode("AutoDbSet", "1.0.0.0")]

public partial class MyCoolDbContext

{

    public required Microsoft.EntityFrameworkCore.DbSet People { get; init; }

}

```

## Caveats

The generator only works when there's a single `DbContext` with the attribute in the project.

I plan to add support for multiple contexts in a future update.
