This chapter covers key concepts such as creating models, adding fields, defining computed methods, building an application, introducing new buttons, configuring smart buttons, and setting up filters and a status bar. Studio makes it easy to add new models (tables) and fields (columns) directly to the database without complexity. In Odoo, buttons are used to trigger specific actions, methods, or workflows, while smart buttons provide quick access to related records by opening linked document views. When working with large volumes of data, filters play an essential role in improving usability by helping users narrow down information efficiently. Users can create custom filters and even set default ones based on their needs. The status bar displays the current stage or state of each record, offering clear visibility into process progress and supporting smoother functional operations.
