link a cartridge SKU to a FormField on a product page

Question

Hello my dear programmers,

i am trown into the deep with this project. i need to build a e-commerce website but a little bit different, this person does not want a checkout cart but a contact form underneath every product with a field for:
name
product
textfield

we need to make it so the SKU of the product on that page gets inserted in the product field.

maybe there is a way to do it with a url instead, that it automaticly pastes the products URL in a textField.

i hope someone can give me some directions i need to look in or some documentation to read.

In Django, you can define URLs with regular expressions (as I'm sure you know). So a URL for a product page might look something like this:

url(r'^product/(?P<sku>\d+)$'

When the view is called from this URL, the sku is passed in as a keyword argument to the view. Then, when the template is rendered from the view, you can pass the keyword argument in as a variable:

{{ sku }}

This variable should automatically be included if extending a DetailView (otherwise use get_context_data).

Therefore, with a little Django templating (perhaps even Javascript), it should be a breeze to prepopulate form fields in your front-end templates with the SKU.
