使用findAll，List（）或SQL Query返回列表中的所有域值

Question

我正在尝试检索所有存在的域值并将它们放入列表中。我正在使用模式对话框来显示此列表，但是目前检索的所有值都只是我正在查看的实例中存在的值，而不是检索数据库中存在的所有值。 / p>

因此，对于每个模板，有许多步骤，即我们正在处理的关系。当我打开模型对话框以检索数据库中的所有步骤时，它只显示该模板上存在的步骤。一些截图可能有助于解释。

包含模态对话框的Show.gsp页面。

<div id="basicModal" title="Existing Template Steps">
    <g:include controller="templateStep" action="renderAllStepsList" />
</div>

控制器 - 而不是使用服务我尝试过TemplateStep.findAll（“来自TemplateStep作为ts”）以及TemplateStep.list（），但它们都具有相同的效果。

def renderAllStepsList(){
    def templateStepInstanceList = TemplateStepService.getSuggestedTemplateSteps() 
    render(template:"list", model: [templateStepInstanceList: templateStepInstanceList])
}

服务

def getSuggestedTemplateSteps() {
    def sql = new Sql(dataSource)
    def rows = sql.rows("select distinct * from template_steps")

    def listOfSteps = rows.collect()

    return listOfSteps
   }
 }

这是目前的模态对话框。如您所见，它向我展示了Template实例中存在的所有步骤，但是我想要检索数据库中存在的所有步骤。这可能吗？
