[2.2-Scala] CSV template

[Deenar Toraskar]

Hi

I am trying to create a CSV template in a play 2.2 application, but cannot find any documentation or samples using a CSV template. I figured out that creating a file xxx.scala.txt generates a xxx.template.scala class in the views/txt package, but any more documentation of samples would be appreciated.

Any template will be processed and output plain text. What this "text" means is up to you. It can be a HTML page, a XML, a properties file or even a CSV.

You could write a scala template as simple as

@(items: Seq[MyItemModel])

My Field A; My Field B; My Field C; My Field D

@for(item <- items) {@item.fieldA;@item.fieldB;@item.fieldC;@item.fieldD

}

That would output, for instance,

My Field A; My Field B; My Field C; My Field D

ValueA1;ValueB1;ValueC1;ValueD1

ValueA2;ValueB2;ValueC2;ValueD2

ValueA3;ValueB3;ValueC3;ValueD3

ValueA4;ValueB4;ValueC4;ValueD4

I would strongly recommend against generating CSV in a template. What happens when they want it to generate comma separated values, or quote everything except numbers, or, or, or...

I've used OpenCsv in the past, as have several of my friends, and we have found it very nice to use, it also works in the other direction, converting CSV into Map and so forth.

Many thanks for both the responses. I had overlooked the quoting part. I already use opencsv for parsing incoming CSV files, so will go down that route for returning results as well.

I'll give opencsv a try too, if I ever need to handle CSV files. Thanks for the suggestion, Bryan.
