Flask-LazyViews 0.5.1

For application

project/app.py

from flask import Flask
from flask.ext.lazyviews import LazyViews


app = Flask(__name__)
views = LazyViews(app)

views.add('/', 'views.home')
views.add('/page/<int:page>', 'views.page')

project/views.py

from flask import render_template


def home():
    return render_template('home.html')


def page(page_id):
    page = get_page(page_id)
    return render_template('page.html', page=page)

For blueprint

project/app.py

...

from project.test import blueprint as test_blueprint

...

app.register_blueprint(test_blueprint, url_prefix='/test')

project/test/__init__.py

from flask import Blueprint
from flask.ext.lazyviews import LazyViews


blueprint = Blueprint('test', __name__)
views = LazyViews(blueprint, '.views')

views.add('/', 'test')
views.add('/advanced', 'advanced_test', methods=('GET', 'POST'))

project/test/views.py

from flask import render_template, request


def advanced_test():
    context = generate_context(request.form)
    return render_template('test/advanced.html', **context)


def test():
    return render_template('test/test.html')

Important

Be careful with import_prefix value if you used __name__ as Flask application name or blueprint import_name. Setting relative path could cause server errors.

add_admin

Add admin view if Flask-Admin extension is added to Flask application.

admin = Admin(app)
views = LazyViews(app, 'views')
views.add_admin('PageAdmin', name='Page Admin')

add_error

Add error handler to Flask application or blueprint, e.g.:

views = LazyViews(app, 'views')
views.add_error(404, 'error')
views.add_error(500, server_error_view)

add_static

Add custom URLs for serving static files. It useful when you want handle some static files outside static_url, e.g.:

views = LazyViews(app)
views.add_static('/favicon.ico', defaults={'filename': 'img/favicon.ico'})
