ORDA – Say Goodbye to Empty Spaces in Your Entity Selections

We’ve all been there. You build a beautiful interface that displays an entity selection for users. They can drop entities to refine their choices, but then… those empty spaces appear where the dropped entities used to be.

Rebuilding the entity selection after drops? No more! 4D 20 R6 introduces a handy feature that eliminates this pain point with just one line of code.

Keep reading to discover how this feature can keep your interface clean and your users happy.

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.

ORDA: Assigning a path to a blob or picture attribute

Non-ORDA database commands allowed you to put images and blobs outside your data file thanks to the SET EXTERNAL DATA PATH command. This command is not adapted for ORDA, so we have decided to add similar functionality in v20 R3: The ability to assign to a blob or picture attribute a path pointing to a file. Let me tell you more about it.

Logging ORDA Calls on the Server

Since its release, ORDA has grown in popularity and is now widely used on your production servers.

With 4D v20, we provide two improvements on how ORDA requests are logged server-side:

  1. The first is an improvement of the request log that will now give more information about ORDA calls.
  2. The second is the addition of a server-side ORDA log similar to the client-side ORDA log. Let me introduce you to these new features.

Data Explorer Embedded in 4D

Data Explorer allows you to view the data in your database. You can choose which fields to display, organize, filter, and sort the data.

With 4D v20, the Data Explorer can be opened in 4D instead of an external browser. Users can access the Data Explorer directly from the toolbar with just one click, saving time and improving productivity.

Meet the Improved Distinct Function

Retrieving the list of unique data elements is always helpful when manipulating data. In some cases, retrieving the number of occurrences of each value is essential. The distinct function of the Collection and Entity selection classes allows retrieving a list of unique values. With 4D v20, you can also retrieve the number of occurrences of each distinct value.

And that’s not all!

An object in the database can be used to save custom data entered by the user. So on the code side, you need to know all the possible paths to the object. The distinctPaths function has been added to the Entity selection class.

Here is everything you need to know.

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.
