The template uses Jinja2 template engine and by default looks for a templates directory in your project.

If your templates directory has the default template files like list.html or create.html then they wiill be used. Otherwise you can create custom templates and use them.

Customizing templates

As the first step you should create a templates directory in you project.

Since Jinja2 is modular, you can override your specific template file and do your changes. For example you can create a custom_details.html file which overrides the details.html from SQLAdmin and in the content block it adds custom HTML tags:

Example

```html name="custom_details.html" {% extends "details.html" %} {% block content %} {{ super() }}

Custom HTML

{% endblock %}

```python name="admin.py"
class UserAdmin(ModelView, model=User):
    details_template = "custom_details.html"

Customizing Jinja2 environment

You can add custom environment options to use it on your custom templates. First set up a project:

from sqladmin import Admin
from starlette.applications import Starlette


app = Starlette()
admin = Admin(app, engine)

Then you can add your environment options:

Adding filters

def datetime_format(value, format="%H:%M %d-%m-%y"):
    return value.strftime(format)

admin.templates.env.filters["datetime_format"] = datetime_format

Usage in templates:

{{ article.pub_date|datetimeformat }}
{{ article.pub_date|datetimeformat("%B %Y") }}

Adding tests

import math

def is_prime(n):
    if n == 2:
        return True

    for i in range(2, int(math.ceil(math.sqrt(n))) + 1):
        if n % i == 0:
            return False

    return True

admin.templates.env.tests["prime"] = is_prime

Usage in templates:

{% if value is prime %}
    {{ value }} is a prime number
{% else %}
    {{ value }} is not a prime number
{% endif %}

Adding globals

def value_is_filepath(value: Any) -> bool:
    return isinstance(value, str) and os.path.isfile(value)

admin.templates.env.globals["value_is_filepath"] = value_is_filepath

Usage in templates:

{% if value_is_filepath(value) %}
    {{ value }} is file path
{% else %}
    {{ value }} is not file path
{% endif %}
