I see in Play there are 3 ways to specify routes, as shown above, which way is considered the recommended one? Which folder structure is better?

...

ANSWER

Answered 2020-Apr-20 at 11:18

Your first code example uses a SIRD router, whereas the second example uses a generated router from a routes file.

The third example just uses a routes file which generates a router that passes control to another router for a specific prefix -- no matter whether this was generated or hand-coded. So, this is no different than the second example.

There is no clear advantage of one over the other. Using a routes files is usually more succinct and "easier", but you have more control when using the DSL to bind your routes to some actions.

The folder structure is also merely a matter of taste; go with the default layout and you should be fine.

ANSWER

Answered 2018-Apr-12 at 10:04

Spark 2.2.0 is built and distributed to work with Scala 2.11 by default. To write applications in Scala, you will need to use a compatible Scala version (e.g. 2.11.X). And your scala version is 2.12.X. That's why it is throwing exception.

ANSWER

Answered 2018-Feb-18 at 13:37

The filename which you get by picture.filename describes the actual path of the uploaded file on the user's computer.

In this case it looks like the user was using a windows machine, and the actual path of file was C:\Users\jungj\Downloads\play-scala-starter-example.zip.

So, the value of /tmp/$filename will be /tmp/C:\Users\jungj\Downloads\play-scala-starter-example.zip which will be a totally invalid path.

So, what you actually need is a way to reliably extract actual filename from the foreign path in user's computer.

You can use org.apache.commons.io.FilenameUtils for this,

Add commons.io as dependency (in your build.sbt),

Scala/Play: how to write JSON result from async db call to http Ok

Asked 2018-Feb-02 at 13:39

Q: Where is the correct place to be calling Ok() to send http response from an async database call?

I have taken the very basic Scala Play framework tutorial play-scala-starter-example as a starting point and adding some additional basic Controller / Service classes that make use of ReactiveCouchbase for database access.

The application successfully:

Connects to Couchbase
Stores a JSON document in Couchbase
Retrieves the stored JSON document from Couchbase
Logs the contents of the JSON to the console

I am new to Scala/Play and can't work out the correct way to succesfully write the JSON back to the http response using Ok(), when the async db call completes.

Inside the Controller class is the following function:

non-Play Sbt Scala sub-project not found in root folder of Play 2.6.3 project

I used the Gitter Play Scala Seed template to create a starter project. I later decided to add another one of my projects as a sub-project to this one by following these and these instructions. However, even though I added the sub-project folder and referred to it from my build.sbt file, whenever I run update (or any of its dependencies) I am getting an error saying that the sub-project cannot be found.

ANSWER

Answered 2017-Mar-16 at 17:24

@Singleton usually refers to a managed singleton in an IOC (Inversion of Control) framework, like Guice (see Scopes) or Spring.

That's a difference to object, which is a singleton managed by the ClassLoader.

In theory, you can have multiple applications running at the same time, using different @Singleton objects of the same class. But they will all use the same object as long as they share a ClassLoader.
