Retrieve related objects in DetailView

In my DetailView, I want to get the object as per the kwargs in my url, plus also retrieve all the related (foreignkey) values of it.

I use:

queryset = Category.objects.select_related()

in the views, however, trying to access the related data using 

{% for i in category.all %}

However, nothing shows in template when rendered.

I tried this in template

{% for i in category.toolkit_set %}

and it said the related object isn't iterable

I have in a jiffy, this my models.py:

class Category(models.Model):
    ....
    title = models.CharField(max_length=250)
    ....

class Toolkit(models.Model);
    ....
    category = models.ForeignKey('Category')

I want to get the object of Category per the slug, plus retrieve all the associated related data in one db hit.

Firstly, you have to use the same variable name to access the Category object as you have elsewhere in the template. Usually in a DetailView, unless you've explicitly changed it, the object name is just object.

Secondly, you have the two separate parts of accessing the related objects - _set and all - but you don't seem to have put them together.

So, it should be:

{% for toolkit in object.toolkit_set.all %}
