When we want to render a view using a template and the template makes use of a model object, the model object needs to be passed to the template using GSP tags. I am writing this because it took me a while to figure this out. Thanks to the wonderful contributors on the mailing list who helped me with this.<\/p>\n

To render the view to a template from a gsp<\/strong> we need to use this tag in your gsp<\/strong><\/span><\/p>\n

<g:render template=”\/templateName”\/><\/p>\n

To send a bean to the template we have to include\u00a0 an attribute to the tag like this<\/span><\/p>\n

<g:render template=”\/templateName” bean=”beanName”\/><\/p>\n

(or) we can also use a named variable in the template.For this we have to send a model<\/span><\/p>\n

<g:render template=\"\/templateName\" model=\"beanName:${someBeanName}\"\/><\/pre>\n
In the template we can use this by calling ‘it’\u00a0 but that’s not my preferred way. The other way is, assign this value to a variable in the template like this.<\/p>\n
<g:set var=\"variableName\" value=\"${beanName}\"\/><\/pre>\n
Now we can use the variableName in the template.<\/p>\n
Example<\/span>:<\/p>\n
<input type=\"text\" id=\"fieldId\" class=\"${hasErrors(bean: variableName, field:\r\n'fieldName', 'errors')}\" name=\"fieldName\" value=\"${fieldValue(bean: variableName,\r\nfield: 'fieldName')}\"\/><\/pre>\n","protected":false},"excerpt":{"rendered":"
