Groovy server page, creating a table

I have a situation where my domain has two fields such as

Class test{
   static constraints {
     testno(nullable:true)
     opt(nullable:false, blank:false)
   }

   Double testno
   String opt
}

The opt has option values such as 'test', 'try', and 'final'.

Now I need to create a table in .gsp file using the above info such that

----------------------------------
         Test        Try       Final
-------------------------------------
TestNo   
-------------------------------------

The value for each opt is display as testNo in the row below.

I am not sure how to start here. I tried creating a table such that:

```<%
def column=[
['field':'Test'],
['field': 'Try'],
['field':'Final']
]
%>```

However, how do I add row in the table? In addition, how can I use the table in a different gsp table given that

class Result(){ test(nullable:true) hasMany=[test:Test]}

I would like it to render the table.gsp in result.gsp

Solution

You need to send all your tests to the view in your controller:

def showTests() {
    // your controller code
    [tests: Test.findAll()]
}

Then, render the data using gsp tags in your view file (e.g. showTests.gsp):

<html>
   <body>
     <table>
     <tr>
       <th></th>
       <th>Test</th>
       <th>Try</th>
       <th>Final</th>
     </tr>
    
     <g:each in="${tests}" var="t">
      <tr>
        <td>${t.testno}</td>
        <td>${t.opt == "test" ? "x" : ""}</td>
        <td>${t.opt == "try" ? "x" : ""}</td>
        <td>${t.opt == "final" ? "x" : ""}</td>
      </tr>
     </g:each>
    </table>

   </body>
</html>

This is just a very simple solution to your problem.

Using it as a subresource

If your Tests are contained in another resource like Result, you can access them in two ways.

If you send your entire report to your view you can use:

// controller
def showResult() {
    // your controller code
    [result: Result.get(/*id...*/)]
}

// showResult.gsp view, just change this line
<g:each in="${result.tests}" var="t">

Otherwise, if you want to send only tests to your existing view from the main example above:

// controller
def showTests() {
    // your controller code
    def result = Result.get(/*your id*/)
    [tests: result.tests]
}
