Hi,

I'm a newbie in PlayFramework

I got this error

No instance of play.api.libs.json.Format is available for scala.Option[reactivemongo.bson.BSONObjectID] in the implicit scope (Hint: if declared in the same file, make sure it's declared before)

How to solve it please ?

Hi, I was wondering if there's a way to resolve the collection Future. If in Todo.scala model, this -

def collection: Future[JSONCollection]

could be converted to -

def collection: JSONCollection

Then in every query we could remove the collection.flatMap.

Example -

def addTodo(todo: Todo): Future[WriteResult] = {
   collection.flatMap(_.insert(todo))
}

would become -

def addTodo(todo: Todo): Future[WriteResult] = {
  collection.insert(todo)
}

Howdy,

first many thx for this use case with swagger and play

My question is... do you have maybe a example on how to use storage for images upload within a mongo document ect. maybe even extend your todo with attachments as example.

i can't find any examples for play mongo crud with images/attachments and really like to see some best practice thingy, if possible with swagger as wrapper around it.. that would be awesome.

Best regards,

It will be awesome to have reactive mongo examples of aggregation queries to this application, but a todo application is a bit trival for this. I would suggest aggregation implementation for the mongo bios-example-collection

No Json serializer found for type Seq[models.Todo]. Try to implement an implicit Writes or Format for this type.
