When Qodly.com Meets 4D Server, What Are They Talking About?
Last September, 4D unveiled Qodly Studio for 4D, offering comprehensive benefits that enable you to seamlessly create dynamic, efficient business web applications. If you haven’t yet, check out this blog post to learn how to get started with Qodly Studio for 4D.
Qodly Studio is also accessible on qodly.com, forming a part of 4D’s new SaaS offering.
Excitingly, the synergy between Qodly.com and 4D applications reaches new heights with the introduction of the QodlyScript openDatastore command. This feature enables qodly.com web applications to seamlessly connect with 4D applications deployed on 4D Servers, facilitating the utilization of 4D projects as remote datastores. So, if you’re eager to harness the power of your 4D application data and business logic within a qodly.com environment, you’ll be delighted to learn about the possibilities offered by Qodly Studio’s latest advancements.
Now, picture this scenario: your existing 4D Server-based application serves both desktop and web clients using Qodly forms. If this setup mirrors your current approach, feel free to skip ahead.
But if you want to extend your existing 4D server-based application with a totally new one, only web-based – and this one hosted on Qodly.com then this post is for you and shows how to communicate between both.
ORDA – Restrict Data to Relevant Criteria
In 4D 19 R8, we introduced a robust permission system, granting you granular control over user access to your data. This system protects your data depending on who accesses it and which data is accessed, ensuring data security by restricting unauthorized access.
But what if you wanted to further refine read access based on specific criteria?
That’s where 4D 20 R5 steps in. Restricting read data according to some criteria.
Improved 4D Client Licenses Usage with Qodly Studio for 4D
Those of you who have started using Qodly Studio for 4D already know how powerful this new tool is for developing business web applications. If you haven’t yet, find here more information on getting started.
Apps made with Qodly Studio for 4D rely on the REST APIs. 4D 20 R5 is shipped with a great new feature: “Force Login” mode.
With Force Login mode, a 4D Client license is only consumed when users successfully log in and begin working with your application’s data and logic.

4D keeps your selections of records consistent regarding deletion of records
Deletion of data should be handled with care. To prevent issues, we can use transactions or rely on backups and logs.
Some improvements have been made in 4D 20 R4 to make your selections of records stable and consistent regarding potential deletion of records in this selection.

Qodly Studio in action with a new demo
In this previous blogpost, we provided some demos to help you starting with Qodly Studio.
As promised, we keep providing demos. Here is the latest PIQS (short for Play In Qodly Studio)
Qodly Studio in Action With These 3 Demos
In those previous blog posts, we announced the availability of Qodly Studio (currently in developer preview) to all our silver partners (and higher). We also gave you the first steps to get started with the tool.
Now it’s the perfect time to dive in and experiment with it by running some concrete demos!
We’ve been offering HDIs (How Do I?) guides for years to help you discover new features. But now, as we venture into this new era of web development, we’ve come up with a new term for these demos: PIQS, short for Play In Qodly Studio.
Even better, we’ll continue providing such demos for current and upcoming Qodly features. This means you’ll have daily guidance on mastering Qodly Studio!
So, let’s roll up our sleeves and start exploring right away!
Enhanced Error Management in 4D Code
Throwing errors in your 4D code is now possible starting from v20R2.
Those errors behave as any 4D error: they trigger an error dialog or can be handled in an ON ERR CALL method.
This feature will ease your life because you’ll be able to improve the quality of your code by proactively detecting errors as soon as they occur. You can also handle better error logging.
Before digging into details, It’s important to note that this feature is the first step towards achieving robust error management.
Now, let’s dig into the details!
ORDA – From Beginner to Expert
ORDA, which stands for Object Relational Data Access, is a method of accessing data that combines the advantages of object-oriented programming with those of relational databases, allowing developers to focus on solving business problems rather than managing data access.
Whether you are new to ORDA or already familiar with it and want to expand your knowledge, consider this blog post a road map to guide you through the learning process.
This blog post includes the following:
- ORDA benefits
- ORDA overview
- Main concept
- ORDA APIs
- ORDA abstraction layer
- Working remotely
- Requests optimization
- Permissions system
- Sharing data between process
Without further ado, let’s get down to business!
Filter Access to your Data with a Complete System of Permissions
Filter access to data is a must-have feature to prevent malicious access to your application.
So far, you could expose or not expose as a REST resource a dataclass and some of its attributes. It was already a convenient means to restrict access to your data. Still, we’re thrilled to deliver in the v19R8 a powerful and fully customizable system to protect your data from unauthorized users. A system to protect your data depends on who is accessing it and which data is accessed.
ORDA – REST request optimization step by step (+ A demo)
ORDA/REST performance is a strategic matter; that’s why we shipped many features related to this topic, such as the ORDA/REST request optimization in Client/Server and when working with a remote datastore. Lately, we also gave you complete control over the ORDA/REST request optimization.
This blog post gives you the plan to follow in order to ace your ORDA/REST performance game. It includes other blog posts to read, videos to watch, and a demo to play with to increase performance in your applications quickly and easily.
