# SearchObject::Plugin::GraphQL
[SearchObject](https://github.com/RStankov/SearchObject) plugin for [GraphQL Ruby](https://rmosolgo.github.io/graphql-ruby/).
## Installation
Add this line to your application's Gemfile:
```ruby
gem 'search_object_graphql'
```
And then execute:
$ bundle
Or install it yourself as:
$ gem install search_object_graphql
**Require manually in your project**
```ruby
require 'search_object'
require 'search_object/plugin/graphql'
```
## Dependencies
- `SearchObject` >= 1.2
- `Graphql` >= 1.5
## Changelog
Changes are available in [CHANGELOG.md](https://github.com/RStankov/SearchObjectGraphQL/blob/master/CHANGELOG.md)
## Usage
Just include the ```SearchObject.module``` and define your search options and their types:
```ruby
class PostResolver < GraphQL::Schema::Resolver
include SearchObject.module(:graphql)
type [PostType], null: false
scope { Post.all }
option(:name, type: String) { |scope, value| scope.where name: value }
option(:published, type: Boolean) { |scope, value| value ? scope.published : scope.unpublished }
end
```
Then you can just use `PostResolver` as [GraphQL::Schema::Resolver](https://graphql-ruby.org/fields/resolvers.html):
```ruby
field :posts, resolver: PostResolver
```
Options are exposed as arguments in the GraphQL query:
```
posts(name: 'Example') { ... }
posts(published: true) { ... }
posts(published: true, name: 'Example') { ... }
```
### Example
You can find example of most important features and plugins - [here](https://github.com/RStankov/SearchObjectGraphQL/tree/master/example).
## Features
### Documentation
Search object itself can be documented, as well as its options:
```ruby
class PostResolver < GraphQL::Schema::Resolver
include SearchObject.module(:graphql)
description 'Lists all posts'
option(:name, type: String, description: 'Fuzzy name matching') { ... }
option(:published, type: Boolean, description: 'Find published/unpublished') { ... }
end
```
### Default Values
```ruby
class PostResolver < GraphQL::Schema::Resolver
include SearchObject.module(:graphql)
scope { Post.all }
option(:published, type: Boolean, default: true) { |scope, value| value ? scope.published : scope.unpublished }
end
```
### Additional Argument Options
Sometimes you need to pass additional options to the graphql argument method.
```ruby
class PostResolver < GraphQL::Schema::Resolver
include SearchObject.module(:graphql)
scope { Post.all }
option(:published, type: Boolean, argument_options: { pundit_role: :read }) { |scope, value| value ? scope.published : scope.unpublished }
end
```
### Accessing Parent Object
Sometimes you want to scope posts based on parent object, it is accessible as `object` property:
```ruby
class PostResolver < GraphQL::Schema::Resolver
include SearchObject.module(:graphql)
# lists only posts from certain category
scope { object.posts }
# ...
end
```
If you need GraphQL context, it is accessible as `context`.
### Enums Support
```ruby
class PostSearch
include SearchObject.module(:graphql)
OrderEnum = GraphQL::EnumType.define do
name 'PostOrder'
value 'RECENT'
value 'VIEWS'
value 'COMMENTS'
end
option :order, type: OrderEnum, default: 'RECENT'
def apply_order_with_recent(scope)
scope.order 'created_at DESC'
end
def apply_order_with_views(scope)
scope.order 'views_count DESC'
end
def apply_order_with_comments(scope)
scope.order 'comments_count DESC'
end
end
```
### Relay Support
Search objects can be used as [Relay Connections](https://graphql-ruby.org/relay/connections.html):
```ruby
class PostResolver < GraphQL::Schema::Resolver
include SearchObject.module(:graphql)
type PostType.connection_type, null: false
# ...
end
```
```ruby
field :posts, resolver: PostResolver
```
