Learn how Odoo stores its data in the Postgres Database 

Fortunately many of the complexities of SQL queries and direct database operations are hidden from us because of Odoo's powerful ORM and API that we have discussed in other videos. Still, all of Odoo's critical data is stored inside a Postgres database that is the engine behind all the operations. In this video we explore that engine for a very specific business driven requirement.

Learn how to see every query that Odoo generates

The core of this video is to demonstrate how you can monitor the queries that Odoo generates for each operation. You will no longer have to guess what Odoo is doing to your data. In this video we show you how you can see the exact Insert, Update, and Delete statements that Odoo creates in real time.

Critical skills for database recovery and troubleshooting 

Ever get that dreaded "Invalid View Architecture" or other "Internal Server Errors" that prevent your Odoo database for starting up? Well all too often it is a corrupted view in your Odoo database. Rather than having to throw out your database and start over, learn how you can get into ir_ui_view, find the bad records and see the XML architecture directly in Postgres.

How does Odoo CMS store website pages?

If you are working with Odoo's website builder you may have wondered how does Odoo maintain the pages, the content on the pages, and what could i do to perhaps make a copy of an Odoo website. Well unlike many traditional websites, Odoo does not store website pages in files on your server. Instead all of your website content is stored in Postgres tables within that Odoo database.

The importance of ir_ui_view in Odoo applications

When you see a view inside of Odoo that record is store in the table ir_ui_view within that database. It doesn't matter if it is the purchase order form inside Odoo's classic ERP framework or a web page added within the website builder. As you will learn in this video, when the Odoo server starts up the views from the modules are updated in the database if required. 

Why would I care about how Odoo stores data inside Postgres?

For developers and Odoo integrators it is vital that you have a clear understanding of Odoo's database architecture. In this video we look specifically at how Odoo manages the various view and forms and the related tables inside Odoo.  When you go to write an Odoo module it is most likely it will involve creating and updating records of some kind inside Odoo. While the ORM does a great job of hiding complexity, it is valuable to understand exactly the data that is in Odoo and how it relates to the transactions in the application you are working on.

The value of seeing the queries that Odoo creates

In this video we explore the value of logging Postgres queries and analyzing them as Odoo creates and updates records. When developing modules that integrate with Odoo or for our specific purpose, copies web pages from one Odoo database to another Odoo database; it is very helpful to see exactly what data gets created and updated inside of Odoo. While looking through the code is of course quite valuable as well, it is possible to miss something with all the various layers and objects interacting with each other. By looking critically at the queries that are executed inside Postgres you can see EXACTLY what data is updated inside of Odoo. This is perfect for creating data conversion utilities, EDI integration, or collaborating with external web services.

Recovering from 'Invalid XML View Architecture'

If you have worked seriously with OpenERP / Odoo and have done any kind of development it is probably inevitiable you have encountered an Invalid XML View Architecture error or Internal Server Error that can often be traced back to a bad view in ir_ui_view. In this video we take a look at that table and demonstrate how changes in that table can be seen in the source within the website builder. By locating the id from the error you received in your log within ir_ui_view and making the necessary corrections in the XML (or deleting the view entirely) you can often recover Odoo databases that refuse to come up and appear corrrupted. While this video is not specifically on database recovery, we look at the specific table that is most often responsible for many common failures in getting Odoo to startup successfully.
