The Django Template Does Not Exist error is a common issue that developers face when working with Django templates. This error occurs when Django is unable to find a template file that is being referenced in your code. In this article, we will explore the causes of this error and provide a step-by-step guide on how to fix it.
Understanding the Error
The Django Template Does Not Exist error is typically raised when Django's template loader is unable to find a template file that is being requested. This error can occur due to a variety of reasons, including:
- Typographical errors in the template name or path
- Incorrect template directory configuration
- Missing template files
- Incorrect template loading settings
Troubleshooting the Error
To fix the Django Template Does Not Exist error, follow these steps:
1. Check the Template Name and Path
The first step is to verify that the template name and path are correct. Check the template name and path in your code and ensure that they match the actual file name and location.
2. Verify Template Directory Configuration
Next, verify that the template directory is configured correctly. Check the TEMPLATES setting in your Django project's settings.py file to ensure that the template directory is included.
TEMPLATES = [
{
'BACKEND': 'django.template.backends.django.DjangoTemplates',
'DIRS': [os.path.join(BASE_DIR, 'templates')],
'APP_DIRS': True,
'OPTIONS': {
'context_processors': [
'django.template.context_processors.debug',
'django.template.context_processors.request',
'django.contrib.auth.context_processors.auth',
'django.contrib.messages.context_processors.messages',
],
},
},
]
3. Check for Missing Template Files
If the template file is missing, create it in the specified directory. Ensure that the file name and extension match the template name and path specified in your code.
4. Verify Template Loading Settings
Finally, verify that the template loading settings are correct. Check the TEMPLATE_LOADERS setting in your Django project's settings.py file to ensure that the correct template loaders are specified.
TEMPLATE_LOADERS = (
'django.template.loaders.filesystem.Loader',
'django.template.loaders.app_directories.Loader',
)
Best Practices to Avoid the Error
To avoid the Django Template Does Not Exist error, follow these best practices:
- Use consistent naming conventions for template files and directories.

Common Pitfalls
- Using incorrect template names or paths.
