@InputType and @Table

[kailey16]

Hello! I am trying to use a class decorated with @ ObjectType and @ Table also as an input type. When I add all three decorators to class I get an error of

{ Error: Model not initialized: File cannot be instantiated. "File" needs to be added to a Sequelize instance.

  message:
   'Model not initialized: File cannot be instantiated. "File" needs to be added to a Sequelize instance.' }

My code looks like

@ObjectType()
@InputType('FileInput')
@Table({
  timestamps: false,
  tableName: 'file'
})
export class File extends Model<File> {
  @Field(() => ID)
  @AutoIncrement
  @PrimaryKey
  @Column({ field: 'file_id' })
  public id!: string;
...
}

Is it not possible to use all three decorators together? I am using sequelize(5.21.12) and sequelize-typescript(1.1.0).

"File" needs to be added to a Sequelize instance.

Is it a TypeGraphQL issue?

[kailey16]

So error only happens when @ Table and @ InputType are together, it does not happen when only @ ObjectType and @ InputType are together. Just curious if there is any rule using @ Table and @ InputType together!

[MichalLytek]

You should always keep input type separated because it's describing completely different aspect of the app.
There's a reason why there's no unified @Type.

Thank you very much!
