Prevent duplicates for a certain GraphCool model


Prevent duplicates for a certain GraphCool model

With these it helps The easiest way to do so is by enabling the "Unique" constraint for a certain field (studentNumber in your case for the Student model). You can enable constraints in the structure view when editing a model.
Note: Under the hood, this creates a unique index in the database just like you suggested.

I wish this help you thanks for using Graphcool!
First things first. As you point out Graphcool enforces two-way relations when you want to connect types. In some cases you know up front that you only want to query the data in one direction, so it might seem unintuitive that you have to create a two-way relation.
code :
type User implements Node {
  createdAt: DateTime!
  email: String @isUnique
  id: ID! @isUnique
  password: String
  updatedAt: DateTime!
  createdRecords: [Record!]! @relation(name: "CreatedBy")
  modifiedRecords: [Record!]! @relation(name: "UpdatedBy")
}
Get random element from Graphcool?

may help you . The best way to do this is by using the API Gateway pattern.
The idea of that approach is to put a gateway server on top of Graphcool's CRUD API and thus customize the API. With this approach, you'd write an additional resolver function that retrieves the random element for you:
code :
const extendTypeDefs = `
  extend type Query {
    randomItem: Item
  }
`

const mergedSchemas = mergeSchemas({
  schemas: [graphcoolSchema, extendTypeDefs],
  resolvers: mergeInfo => ({
    Query: {
      randomItem: {
        resolve: () => {
          return request(endpoint, allItemsQuery).then(data => {
            const { count } = data._allItemsMeta
            const randomIndex = Math.floor((Math.random() * (count-1)) + 0)
            const { id } = data.allItems[randomIndex]
            return request(endpoint, singleItemQuery, { id }).then(data => data.Item)
          })
        },
      }
    },
  }),
})

this one helps. I am attempting to implement a GitHub Login with GraphCool. So far: ,
I am not sure where to obtain a github code.
code :
<html>

<body>
  <script>
    // Github client id
    const client_id = '__CLIENT_ID__'
    // Will extract code from current url
    const githubCode = window.location.search.substring(1).split('&')[0].split('code=')[1]
    if (githubCode) {
      // call Graphcool authenticateGithubUser mutation
      console.log(githubCode)
    }
    function getgithubCode() {
      window.location = `https://github.com/login/oauth/authorize?client_id=${client_id}&scope=user`
    }
  </script>
  <button onclick="getgithubCode();">Authenticate with Github</button>
</body>

</html>

help you fix your problem For nested structure you need to define one for type variable like below
code :
type User @model {
   id: ID! @isUnique
   position: Position
}
type Position {
  lat: Int
  lng: Int 
}

will help you You need to go to the settings page on your project, click on the authentication tab and get this console command with your token in it.
code :
graphcool login --token "supersecrettokenheresdfasdfawerfasdfawefaweafewafdsafsdfasd"
