Custom Views

Working with Custom Views

BaseView

To add custom views to the Admin interface where you want to access database and SQLAlchemy models, you can use the BaseView. Here’ an example

from sqlalchemy import Column, Integer, String, select, func
from sqlalchemy.orm import sessionmaker, declarative_base
from fastdaisy_admin import Admin, BaseView, expose
from starlette.applications import Starlette

Base = declarative_base()
engine = create_engine(
    "sqlite:///example.db",
    connect_args={"check_same_thread": False},
)
Session = sessionmaker(bind=engine)

class User(Base):
    __tablename__ = "users"

    id = Column(Integer, primary_key=True)
    name = Column(String(length=16))


Base.metadata.create_all(engine)  # Create tables

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


class ReportView(BaseView):
    name = "Report Page"
    icon = "fa-solid fa-chart-line"

    @expose("/report", methods=["GET"])
    async def report_page(self, request):

        with Session(expire_on_commit=False) as session:
            stmt = select(func.count(User.id))
            result = session.execute(stmt)
            users_count = result.scalar_one()

        return await self.templates.TemplateResponse(
            request,
            "report.html",
            context={"users_count": users_count, 'model_view':self},
        )


admin.add_view(ReportView)

you can create report.html inside templates directory with the following content

{% extends "fastdaisy_admin/layout.html" %}

{% block head %}
    <title>{{ admin.title }} - Report</title>
{% endblock %}

{% block breadcrumbs %}
    <div class="flex items-center max-md:p-3 p-5 pb-0 flex-wrap justify-between">
        <div class="text-sm max-md:hidden breadcrumbs">
        <ul>
            <li><a href="{{ url_for('admin:index') }}" class="link link-hover">Dashboard</a></li>
            <li><a href="{{ url_for('admin:list',identity=model_view.identity) }}"class="link link-hover">{{model_view.name}}</a></li>
        </ul>
        </div>
    </div>
{% endblock %}

{% block container %}

<div class="w-full">
  <div class="card bg-base-100 shadow-md">
    <div class="card-body border-b">
      <h3 class="card-title text-lg font-semibold">User reports</h3>
      <p>Users count: {{ users_count }}</p>
    </div>
  </div>
</div>

{% endblock %}

If you want to use a custom templates directory name, you can change that with:

from fastdaisy_admin import Admin

admin = Admin(templates_dir="my_templates", ...)

Now visiting /admin/report you can render your report.html file.

ModelView

You can also add extra endpoint in modelview with the help of expose decorator. The path is in this case prepended with the view’s identity. i.e /admin/user/profile/{pk}

from markupsafe import Markup
from fastdaisy_admin import ModelView, expose

class UserView(ModelView):
    column_list = [User.id, User.name, "detail"]

    @expose("/profile/{pk}", methods=["GET"])
    async def profile(self, request):
        user: User = await self.get_object_for_edit(request)
        return await self.templates.TemplateResponse(
            request, "user.html", {"user": user, "model_view":self}
        )

    def detail(self,obj):
        url = f'profile/{obj.id}'
        return Markup(f'<a href="{url}">📝</a>')
    
admin.add_view(UserView)

In the above example, By adding detail method in column_list will display link that lead to custom view. Keep in the mind that, method must contain one argument, in our case is user object. user.html inside templates directory contains

{% extends "fastdaisy_admin/layout.html" %}

{% block head %}
    <title>{{ admin.title }} - Profile </title>
{% endblock %}

{% block breadcrumbs %}
    <div class="flex items-center max-md:p-3 p-5 pb-0 flex-wrap justify-between">
        <div class="text-sm max-md:hidden breadcrumbs">
        <ul>
            <li><a href="{{ url_for('admin:index') }}" class="link link-hover">Dashboard</a></li>
            <li><a href="{{ url_for('admin:list',identity=model_view.identity) }}"class="link link-hover">{{model_view.name}}</a></li>
            <li>{{ user | string | truncate(40) }}</li>
        </ul>
        </div>
    </div>
{% endblock %}


{% block container %}
