Passing variables to templates in Django

Question

I have seen similar questions and answers but none that address my problem.

I want my view to perform a User Group check and then pass that via variable to the template. The template will then use that to appear differently to different user groups.

My views.py:

def cans(request):
    is_canner = request.user.groups.filter(name='canner') #check if user group = canner
    can_list = Can.objects.order_by('name')
    context = {'can_list': can_list}
    return render(request, 'cans/cans.html', context) #need to return is_canner variable here

And in my template I would use the variable like so:

{% if is_canner %} canner stuff goes here {% endif %}

I'm unsure how to pass this variable, I thought it used context to send it like so:

return render(request, 'cans/cans.html', context({"is_canner": is_canner}))

But this gives me errors - context is not callable.

Answer 1

context is not a function, its an argument to the render function, e.g.

context = {"is_canner": is_canner}
return render(request, 'cans/cans.html', context)
