Question: I've got a model with field `datetime = models.DateTimeField(auto_now_add=True)`. In form created from this model I don't need to edit this field but I need to show it. The fields with `auto_now_add=True` automatically isn't shown. What is the best way to show this field?

Answer: 
Assuming you pass an `instance` when creating form object, you can access it in your template using:

```
{{ form.instance.datetime|date:"Y/m/d H:i:s" }}

```

If you don't have an instance, though, the smartest thing to do would be to use current time:

```
{% now "Y/m/d H:i:s" %}

```
You can display the instance value when editing form like this:

```
{{ form.instance.datetime }}

```
