Solved: no exception message supplied django template

This is my view: def add_item(request): if request.method == 'POST': form = ItemForm(request.POST) if form.is_valid(): item = Item() item.name = request.POST['name'] item.save() return HttpResponseRedirect('/items/') else: return render_to_response('items/add_item...

Exception Message

When an exception occurs in Django, it prints out a message to the console. This message usually contains information about the exception, such as the Python code that caused it.

Modify templates

There are a few ways to modify templates in Django. The simplest way is to use the template tag. For example, to add a header to a template:

{% load header %} {% set header = “My Header” %} {% if not is_page %} {% set header = “My Header” %} {% endif %}

You can also use the context processor to change the context of a template variable:

{% load context %} {% set context = “my_context” %} {% if not is_page %} {% set context = “my_context” %} {% endif %}
