how to use jinja2 in Django 3.1 - django

Question

Now I am using the Django 3.1 template engine but I am not satisfied with it.
But I see that jinja2 template engine is very powerful that it.
Thought Django says it has support for jinja2 template engine and I was following this Django documentation,
but I couldn't use that.
# settings.py
TEMPLATES = [
{
'BACKEND': 'django.template.backends.jinja2.Jinja2',
'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',
],
},
},
{
'BACKEND': 'django.template.backends.django.DjangoTemplates',
'DIRS': [],
'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',
],
},
}
]
Browser Error:
("Encountered unknown tag 'url'. Jinja was looking for the following tags: 'endfor' or 'else'. The innermost block that needs to be closed is 'for'.",)
So, please tell me how do I do it?

Answer 1

You can use multiple engines, but then the directories should be non-overelapping, or you use the engines with a given priority, if you specify with the DIRS setting [Django-doc] what directories belong to which template. But here both are the same, so that means Django will always select the first one.
You thus specify:
# settings.py
TEMPLATES = [
{
'BACKEND': 'django.template.backends.jinja2.Jinja2',
'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',
],
},
},
{
'BACKEND': 'django.template.backends.django.DjangoTemplates',
'DIRS': [],
'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',
],
},
}
]
We thus do not add any items to the DIRS setting for the DjangoTemplates.

here are docs: https://niwinz.github.io/django-jinja/latest/
install jinja2
pip install django-jinja
add into INSTALLED_APPS
INSTALLED_APPS = (
.......
'django_jinja',
.......
)
add into template engines list:
TEMPLATES = [
{
"BACKEND": "django_jinja.backend.Jinja2",
"APP_DIRS": True,
"OPTIONS": {
"match_extension": ".jinja",
}
},
{
"BACKEND": "django.template.backends.django.DjangoTemplates",
"DIRS": [],
"APP_DIRS": True
},
]
