  1. POScala: parsing an API parameter
    text
    copied!<p>My API currently take an optional parameter named gamedate. It is passed in as a string at which time I later parse it to a Date object using some utility code. The code looks like this:</p> <pre><code> val gdate:Option[String] = params.get("gamedate") val res = gdate match { case Some(s) =&gt; { val date:Option[DateTime] = gdate map { MyDateTime.parseDate _ } val dateOrDefault:DateTime = date.getOrElse((new DateTime).withTime(0, 0, 0, 0)) NBAScoreboard.findByDate(dateOrDefault) } case None =&gt; NBAScoreboard.getToday } </code></pre> <p>This works just fine. Now what I'm trying to solve is I'm allowing multiple gamedates get passed in via a comma delimited list. Originally you can pass a parameter like this:</p> <p><code>gamedate=20131211</code></p> <p>now I want to allow that OR:</p> <p><code>gamedate=20131211,20131212</code></p> <p>That requires modifying the code above to try to split the comma delimited string and parse each value into a Date and change the interface to findByDate to accept a Seq[DateTime] vs just DateTime. I tried running something like this, but apparently it's not the way to go about it:</p> <pre><code>val res = gdates match { case Some(s) =&gt; { val dates:Option[Seq[DateTime]] = gdates map { _.split(",").distinct.map(MyDateTime.parseDate _ )} val datesOrDefault:Seq[DateTime] = dates map { _.getOrElse((new DateTime).withTime(0, 0, 0, 0))} NBAScoreboard.findByDates(datesOrDefault) } case None =&gt; NBAScoreboard.getToday } </code></pre> <p>What's the best way to convert my first set of code to handle this use case? I'm probably fairly close in the second code example I provided, but I'm just not hitting it right.</p>
