Installation
npm i adonis-lucid-when --save
Registering provider
Make sure to register the provider inside start/app.js
const providers = [
'adonis-lucid-when/providers/WhenProvider'
]
Usage
First add the trait to the model.
const Model = use('Model')
class User extends Model {
static boot() {
super.boot()
this.addTrait('@provider:Lucid/When')
}
}
Finally use the method as in the example above.
Apply default value
const User = use('App/Models/User')
User.query()
.where('active', true)
.when(request.input('status'), (q, value) => q.where('status', value), 1)
.when(request.input('is_deleted'), (q, value) => q.where('is_deleted', value), false)
.fetch()
The third parameter deals as a default value in case the first variable is falsy.
0 and '0' are not considered falsy
empty array / object is considered falsy
