This example shows how you can change bootswatch themes
To run this example:
1. Clone the repository::
git clone https://github.com/flask-admin/flask-admin.git
cd flask-admin
2. Create and activate a virtual environment::
virtualenv env
source env/bin/activate
3. Install requirements::
pip install -r 'examples/forms/requirements.txt'
4. Run the application::
python examples/forms/app.py
The first time you run this example, a sample sqlite database gets populated automatically. To suppress this behaviour,
comment the following lines in app.py:::
if not os.path.exists(database_path):
build_sample_db()
