how to correctly render controller output to GSP

in my grails application, I have a controller that reads a directory and returns a list of files in it.

My issue is that in my GSP (view) it is not matching the out put from the controller.

Here is my controller:

package frametest

import groovy.io.FileType

class Read_dirController {

    def index() { 

        def list = []

        def dir = new File("D:\\TestRepoLocal\\APIAutomation\\src\\test\\cucumber\\features")
        dir.eachFileRecurse (FileType.FILES) { file ->
          list << file
        }

        list.each {
            println it.name
          }

        def found = []
        dir.eachFileMatch(FileType.ANY, ~/.feature/) {
            found << it.name
        }

        render(view: "index",  model: [name:name])      
    }

}

here is my GSP (view):

<%@ page contentType="text/html;charset=UTF-8" %>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1"/>
<meta name="layout" content="main"/>
<title>Welcome to The Marriot test Page</title>
</head>
<body>
  <div class="body">
    <h2>Marriott Automation Test Page</h2>
    <br>
    <p></p>
    <h3>This is where we can launch our tests and get reports</h3>
    <br>
    <br>
    <p></p>

    ${name}

  </div>
</body>
</html>

The output should just list the file names. It does in the controller output (shown in console), but in the view it shows this:

[D:\TestRepoLocal\APIAutomation\src\test\cucumber\features\APIWAL_525_Account_Security_otp.feature, D:\TestRepoLocal\APIAutomation\src\test\cucumber\features\AssignRoomToReservation.feature, D:\TestRepoLocal\APIAutomation\src\test\cucumber\features\DeleteAccount.feature, D:\TestRepoLocal\APIAutomation\src\test\cucumber\features\DeleteConsumersPaymentMethods.feature, D:\TestRepoLocal\APIAutomation\src\test\cucumber\features\GetActivitiesByID.feature, D:\TestRepoLocal\APIAutomation\src\test\cucumber\features\GetAddressType.feature, D:\TestRepoLocal\APIAutomation\src\test\cucumber\features\GetAddrMiscType.feature, D:\TestRepo

Local\APIAutomation\src\test\cucumber\features\GetAlerts.feature,

the console output for the controller shows this:

APIWAL_525_Account_Security_otp.feature
AssignRoomToReservation.feature
DeleteAccount.feature
DeleteConsumersPaymentMethods.feature
GetActivitiesByID.feature
GetAddressType.feature
GetAddrMiscType.feature
GetAlerts.feature
GetAttractionsByID.feature

What do i need to do to make the view match the controller output from console??

thanks!

UPDATE!!!!!

to solve my listing issue I did this: I changed the controller file to do this little trick:

render(view: "index",  model: [name:list.name])

then to make the gsp list the file names on a new line, I did this:

<ul>
        <g:each in="${name}" var="fileName">
               ${fileName}<br>
        </g:each>
    </ul>

And presto!!

This is where we can launch our tests and get reports



APIWAL_525_Account_Security_otp.feature




 AssignRoomToReservation.feature
 DeleteAccount.feature
 DeleteConsumersPaymentMethods.feature
 GetActivitiesByID.feature
 GetAddressType.feature
 GetAddrMiscType.feature

.....

Thanks guys for encouraging me to struggle to learn it and helping me along the way!

Solution

Your gsp is rendering the list but your list of names is in the variable found, not name. Anyway, your last action line should be:

render(view: "index",  model: [name: found])

In other hand, your gsp is rendering the list, but should give it some style. An example:

<ul>
    <g:each in="${name}" var="fileName">
           <li>${fileName}</li>
    </g:each>
</ul>
