We have recently upgraded to Litium 7 from version 6.x. And we havn’t created definition classes for the existing page templates. Now we have a requirement to add some fields to one of the page templates(through code). I was able to create field definition for the fields, but i don’t know how to add them to the template through code.

All the samples i saw expects me to create definition classes for the  
existing page templates.

Is there a way to add fields to a page template through code without creating page template classes?

Something like

`var sampleTemplate = IoC.Resolve<FieldTemplateService>().Get<PageFieldTemplate>(TemplateNameConstants.SampleTemplateName);`

`sampleTemplate.FieldGroups.FirstOrDefault(fg=>fg.Id=="General").Fields.Add(FieldNameConstants.SampleFieldName);`

Litium version: 7.2.3

Take a look in the files in folder:

> Litium.Accelerator.Definitions.Pages

You will then get some hints.

is a good try and you was only missing a small parts.

Try with the following instead.

```auto
var templateService = IoC.Resolve<FieldTemplateService>(); // Inject the FieldTemplateService in the class instead of using IoC.Resolve.
var sampleTemplate = templateService.Get<PageFieldTemplate>(TemplateNameConstants.SampleTemplateName)?.MakeWritableClone();` // Make writable clone of the template, otherwise the template is read only.

sampleTemplate.FieldGroups.FirstOrDefault(fg=>fg.Id=="General").Fields.Add(FieldNameConstants.SampleFieldName);

templateService.Update(sampleTemplate); // Don't forget to persist the changes.

```
