Can model views in Flask-Admin hyperlink to other model views?

Flask-Admin is a powerful extension for Flask that helps you create administrative interfaces for your web applications. When working with Flask-Admin, you can indeed create hyperlink relationships between model views, allowing you to navigate from one model view to another.

To create hyperlinks from one model view to another in Flask-Admin, you typically use the column_editable_list attribute in your model view classes. Here's an example of how to set up hyperlink relationships between model views:

Suppose you have two models, Author and Book, and you want to create a hyperlink from the Author model view to the Book model view to show all the books by that author.

  • Define your models:
from flask_sqlalchemy import SQLAlchemy db = SQLAlchemy() class Author(db.Model): id = db.Column(db.Integer, primary_key=True) name = db.Column(db.String(255)) class Book(db.Model): id = db.Column(db.Integer, primary_key=True) title = db.Column(db.String(255)) author_id = db.Column(db.Integer, db.ForeignKey('author.id')) author = db.relationship('Author', backref='books')
  • Create model views for both Author and Book using Flask-Admin:
from flask_admin.contrib.sqla import ModelView from flask_admin import Admin admin = Admin(app, name='My Admin', template_mode='bootstrap3') class AuthorView(ModelView): column_editable_list = ('name', 'books') # Add 'books' column as editable # Other view customization options class BookView(ModelView): column_editable_list = ('title', 'author') # Add 'author' column as editable # Other view customization options admin.add_view(AuthorView(Author, db.session)) admin.add_view(BookView(Book, db.session))

In this example:

  • We define two models, Author and Book, with a one-to-many relationship between them. An Author can have multiple books.

  • We create two model views, AuthorView and BookView, using Flask-Admin's ModelView. We specify the column_editable_list attribute to make certain columns editable in the list view. Here, we make the books column in the AuthorView and the author column in the BookView editable.

  • By making the books column editable in the AuthorView, Flask-Admin will render it as a hyperlink. Clicking on the hyperlink will take you to the list of books for that author in the BookView.

This way, you create a hyperlink relationship from the Author model view to the Book model view in Flask-Admin. You can customize the views further based on your specific requirements.
