Print a Variable

View:

def members(request):
    context = {
        "firstname": "Emil",
        "member": {"lastname": "Refsnes"},
    }
    return render(request, "members/template.html", context)

Template:

<p>Hello {{ firstname }} {{ member.lastname }}!</p>

Output: Hello Emil Refsnes!

Attributes vs Keys

Django tries, in order: dictionary lookup, attribute, list index. So member.lastname works for a dict, a model instance, or an object with that attribute.

Filters

A pipe runs a filter:

{{ firstname|upper }}
{{ joined_date|date:"M d, Y" }}
{{ bio|default:"No bio yet" }}
{{ members|length }}

Filter	Effect
`upper` / `lower`	Case
`date`	Format a date
`default`	Fallback if empty
`length`	Count items
`safe`	Do not escape HTML (use carefully)

Auto-escaping

Django HTML-escapes variables so <script> in user data will not run. Only mark content safe when you generated the HTML yourself.

📘 Real-World Deep Dive

Knowing <strong>Django Variables (Django)</strong> well is what turns Django from a curiosity into a daily tool — you'll reach for it in nearly every real project.

Real-Life Scenario

An end-to-end usage of Django Variables that you'd actually see in a data pipeline or analytics notebook.

Real-Life Example

{# templates/welcome.html #}
<p>Welcome, {{ user.username }}!</p>
<p>You have {{ notifications.count }} notifications.</p>

Expected Output

(no output)

Common mistakes

Forgetting to call .save() on a model instance after mutation silently persists nothing.
Reading every row with Model.objects.all() on a 1 M-row table OOMs the worker — use .iterator() for streaming.
Queries inside loops produce N+1 problems — pull related rows with select_related / prefetch_related.
Treating Django Variables as a black box without reading the docs — the API has subtle defaults that bite when you scale.

🚀 Performance & Best Practices

Add database indexes (db_index=True or Meta.indexes) on columns used in filter.
Use cache_page on read-heavy views and set CONN_MAX_AGE to keep DB connections warm.
Generate migrations with python manage.py makemigrations --dry-run --verbosity 3 and review before committing.
When working with Django, prefer vectorised / batched operations over Python loops.

🧪 Try It Yourself

Reproduce the snippet on a representative slice of your own data.
Profile the snippet with cProfile or timeit and find the single biggest improvement.
Generalise the snippet into a small, reusable function you can drop into future projects.
