View Inheritance can be defined as the process of modifying an existing view. This may be adding a new field to an existing view, adding button, adding attribute to an existing field etc.

This document discusses working with arrays in PHP. It covers array basics like creating and accessing arrays, looping through arrays with foreach and for loops, modifying arrays by adding/removing elements and sorting arrays. It also discusses multidimensional arrays, how to create them and access elements within them.

Odoo helps you to set constraints to variants which we can perform using python and model constraints. In odoo python constraints are specified along with methods. This Slide will provide an insight on python and model constraints in Odoo 15. In python, constraints are defined along with a method decorated with constraints().

This slide discusses building a custom module in #odoo15 and also detail each component in the module such as models, views, security, and how can we add those files and set up a module.

ORM(Object Relational Mapping) is a concept or technique which acts as a bridge between your programming language and your database. Object Relational Mapping helps to execute SQL queries without writing them explicitly. Once the ORM is configured in an application, the user can use the OOP concepts like classes and objects to interact with the database. ORM methods are one of its strong features which helps in executing SQL queries without writing them down explicitly. With the help of ORM methods, the user can implement the OOPS concepts to interact with the database. Odoo creates and manages tables for us inside the database. Thus reducing our work of creation of tables using the queries.

The document discusses GET and POST methods in PHP. GET retrieves data from forms by sending name-value pairs in the URL, while POST sends data invisibly within the request. GET has limits on data size and is less secure, while POST has no size limits and is more secure. Both populate the $_GET and $_POST superglobals in PHP. The $_REQUEST variable contains data from GET, POST, and cookies to retrieve form data regardless of submission method.

In delegation inheritance provides more flexibility, we use the _inherits attribute. This is used if you want to sink another model in your current model without affecting the views. So the database tables contain fields in your model and also a field representing the inherited objects.

This document provides an overview of software security best practices and common vulnerabilities for Odoo code. It discusses the top 10 risks including injection, broken authentication, sensitive data exposure, XML external entities, broken access control, security misconfiguration, cross-site scripting, insecure deserialization, vulnerable components, and insufficient logging. For each risk, it provides examples of vulnerable code and recommendations for more secure implementations. It emphasizes that the Odoo framework includes mechanisms to prevent many mistakes but knowledge and mindset are also key. The document concludes with recommendations for code reviews to check access control, permissions, templates, evaluations, injections, and cross-site scripting prevention.

In Odoo 16, the sequence number is a field used to assign a unique, incremental number to records in a specific model. It helps in maintaining the order or sequence of records and can be useful in various scenarios.
