This snippet shows how to disable fields in a edit page in the oldforms admin using jquery.

The idea is to add the javascript to the edit page using the js attribute of the model's Admin class. In this case jQuery and a custom javascript file are added.

The javascript sets the disabled attribute of the name field to true as soon as the document is ready.

Model:

class Placeholder(models.Model):
    name=models.CharField()
    description = models.CharField(blank=True, maxlength=200)
 
    class Admin:
        list_display = ('name', 'description')
        js = (
              '/appmedia/js/jquery.js',
              '/appmedia/js/placeholder.js',
              )

$(document).ready(function(){
   $('#id_name').attr("disabled", true);
});
