caching - Best practice for cache requests on persisted objects in Play/Scala -

-

I'm trying to exclude caching in my play app, and it looks like it's working, But the code hopes me to get more verbose, and I appreciate some comments on the simplification or something else I remember. This question is a bit of an extension code (the presentation is a bit simplified here): 

  def findById (id: int): option [lerner] = {cache.get [lerner] ("Learner." + Id) match {no case = & gt; DB.withConnection {built-in C = & gt; // - No cache, db sql ("select from learning *, where id = {id}") .on ('id -> id) .as (learner p.oneOpt) match {case something (learner) = > And gt; {// - Detected, set the cache cache .Set ("learner.", + Learner.id, learner) some (learner)} case _ = & gt; None // - no address in DB, no cache set}} Case (= learner) = & gt; Some (learners) // - Value of return in cache}}   
 EDIT: The learners (in this case) are important to set cash values ​​anywhere or have been set. Installing is necessary, otherwise before joining, a query will set the cache to someone, and then no future AAS or Getallus call will return no matter, even if a value is present.   
 
 
 You can use the  getOrElse  method like this:  
  cache.get.org else [option] [learner]] ("learner." + Id, end_time) {DB.withConnection {implicit c => // - No Cache, read DB SQL ("ID = ID =" where learning ID = {ID} ") .on ('id - & gt; id) .as (learner p.oneOpt)}}  < / Pre> 
 If the option is found in [learning]  memory, it is returned immediately, if it is not, then DB is called and its result is terminated. Time is cached with  end_time .

I have a requirement whenever I run my own kettle, dynamically took database connection parameters from an excel source Every run should go. I have an Excel column names: hostname, username, database, password. I want to pass these connection parameters to my table input stage dynamically whenever it runs the job. This is what I was trying to do. You can get it Connection parameters from the DB reading source (for example Excel or a CSV file in my example) < / Li> Store the parameters in the variable Using the variable in your connection's settings. Setting Variables Create another conversion for (you can not do it in the same conversion Uses): set variables element variable: The element that reads / writes your data creates a new connection and sets the connection parameter using $ {variable name_} Note that you will need to type in the field field in the field $ {password} Also keep in mind that this can be a security problem as the

I am trying to implement a screen-scraps application that opens a URL in which a parameter changes as it is for a loop: var data = [ '100', '101', '102', '103', '104']; (Var indexA = 0; indexA & lt; data.length; indexA ++) for {Phantom Generation ({'port': freeport}, function (pH) {ph.create page (function (page) {page.open ("http: //...++ data [index B] +" ...

Data is verified in scrap HTML and from index to array Matches. So in page 101 I scrap '101 and retrieve' and pu
