    I think I already asked this, but can't find it (over a week ago!), so I've just come back to it. I've worked through the quickstart tutorial for Vue.js (on my Mac) and all OK (after getting over the package.json license error. So the last two commands are yarn install and yarn start & I get the program running, but when I add a new post and enter some info, it does not save - nothing happens, it just returns to the popup entry dialog - any thoughts ? TIA, Dave

    Hi channel! I've got a problem trying to query a list of events by a range (I want a list of events which are before or after a date, so I can filter passed events or events in the future) My schema is:
    Copy code
    type Event @model {
  id: ID! @isUnique
  title: String!
  description: String!
  type: String
  dateTime: DateTime!
  location: String!
  image: String
  attendants: [Attendant!]! @relation(name: "EventHasAttendant")
  minAttendants: Int!
  maxAttendants: Int!
  updatedAt: DateTime!
  createdAt: DateTime!
}
    My query is something like:
    Copy code
    {
  allEvents(filter: {dateTime: "2017-11-18T23:00:00.000Z"}) {
    id
    title
    description
    type
    dateTime
    location
    image
    attendants {
      id
      email
      name
    }
    minAttendants
    maxAttendants
  }
}
    Could you help me? I don't know if in this case I should use Graphcool Functions.

    I can’t seem to get my 
    graphql subscriptions
    to work. I believe I set it up correctly, but it keep returning null. Here’s my setup
    Copy code
    const Subscription = new GraphQLObjectType({
    name: 'RootSubscription',
    description: 'All FathCircle Subscriptions',
    fields: {
        userCreated: {
            type: UserLoginType,
            subscribe: withFilter(
                () => pubsub.asyncIterator(SUB.USER_CREATED, SUB.USER_LOGGED_IN),
                (payload, args) => {
                    console.log(payload);
                    return payload.userCreated.id === args.id;
                }
            ),
            resolve: st => {
                console.log(st);
                console.log('Nothing shows!!!');
            }
        }})

    Any thought’s appreciated

    So, I edited my permissions for User.* and required authorisation for all CRUD ops. If I use the basic mutation 
    createUser
    without authorisation, I get stopped with an error for insufficient permissions, which is what I expect. However, when using the authorisation template providing the basic email/passwd auth, invoking the mutation 
    signupUser
    doesn’t yield any error, but actually creates the user, even though I can see the source code is (obviously) using the basic 
    createUser
    mutation. Thoughts?

    Hi guys sorry probably I'm becoming annoying but whetever response I receive it doesn't help me to understand when to use functions. At the moment the thing that I did is 1 table: 
    Airline
    on this table I perform CRUD operations. The CRUD operations are defined in my client project (angular with apollo). So my graphcool project atm contain just the schema definition:
  • d
    - in types.graphql:
  • d
    Copy code
    type Airline @model {
  id: ID! @isUnique
  name: String!
  color: String!
}
  • d
    In my client: SELECT, UPDATE, DELETE, ADD
  • d
    Now I'm keep looking all the xamples on the 
    <https://github.com/graphcool/framework/tree/master/examples>
    but I don't find any example to put the CRUD in functions or not
  • d
    can someone point me please in the right direction?
  • v
    Not quite sure I follow what you say there, @daniele — graphcool automatically creates CRUD queries/mutations for you, so your client is supposed to use those for CRUD
  • v
    (maybe I am misunderstanding you)

    If your conversation reaches a point where you need to share a lot of code snippets, it's a good sign that the Forum is a better place to have it: https://graph.cool/forum.
