How to Pass Context to Template in Django: Simple Guide

In Django, you pass context to a template by providing a dictionary of data to the render() function in your view. This dictionary's keys become variable names accessible inside the template for dynamic content rendering.

Syntax

Use the render(request, template_name, context) function in your Django view. Here, request is the HTTP request object, template_name is the path to your template file, and context is a dictionary containing data you want to send to the template.

Each key in the context dictionary becomes a variable in the template.

python

from django.shortcuts import render

def my_view(request):
    context = {'key': 'value'}
    return render(request, 'template.html', context)

Example

This example shows a Django view passing a user's name and age to a template. The template then displays these values dynamically.

python

from django.shortcuts import render

def user_profile(request):
    context = {
        'name': 'Alice',
        'age': 30
    }
    return render(request, 'profile.html', context)

# profile.html template content:
# <p>Name: {{ name }}</p>
# <p>Age: {{ age }}</p>

Output

<p>Name: Alice</p>
<p>Age: 30</p>

Common Pitfalls

• Forgetting to pass the context dictionary to render() results in no data available in the template.
• Using a non-dictionary type for context causes errors.
• Misspelling keys in the template or context dictionary leads to empty or missing values.

Always ensure your context is a dictionary and keys match template variable names.

python

from django.shortcuts import render

def wrong_view(request):
    # Missing context argument
    return render(request, 'template.html')

# Correct way:

def correct_view(request):
    context = {'message': 'Hello'}
    return render(request, 'template.html', context)

Quick Reference

Step	Description
1	Create a dictionary with data to pass.
2	Call render(request, 'template.html', context).
3	Use {{ key }} in the template to access data.

Key Takeaways

Pass a dictionary as the context argument in the render() function to send data to templates.

Template variables correspond to the keys in the context dictionary.

Always ensure context is a dictionary and keys match template variable names exactly.

Forgetting the context argument or using wrong types causes errors or missing data.

Use {{ variable_name }} syntax in templates to display context data.
