Don't want to write the view if it's all ready in there somewhere.


Check out the `Category` module, which is a subclass of Mezzanine's 
`Page`.


Simplest way is

Product.objects.all()

To get that in a template, you might need to write a template tag, e.g. 
I added something to my Orders Change List template so that I could 
filter orders by a specific product (and export the results to CSV). The 
basics are:


In admin.py (or forms.py):

def get_all_products():
    return [(p.id, p.title) for p in 
Product.objects.all().order_by('title')]


class OrderByProductForm(forms.Form):
    product = forms.ChoiceField(label="Export filtered orders containing",
    choices=[])

    def __init__(self, *args, **kwargs):
    super(OrderByProductForm, self).__init__(*args, **kwargs)
    self.fields["product"].widget = 
forms.Select(choices=get_all_products())


templatetags/myapp_tags.py:

@register.simple_tag
def export_order_by_product_form(request):
    querystring = request.GET.dict()
    return OrderByProductForm(queries=querystring)

And then in templates/admin/order_change_list.html:

{% extends "admin/change_list.html" %}
{% load admin_urls myapp_tags %}

{% block object-tools-items %}


   {% export_order_by_product_form request %}
   

{{ block.super }}
{% endblock %}

Note then i have also defined a view for "order_export" which uses the 
selected Form item to find the right orders and export them to CSV.


Hope this helps.

Seeya. Danny.

I am trying to list all products from cartridge, is that function all ready 
in there and how can i call it from a template?
Don't want to write the view if it's all ready in there somewhere.
