Single relations

Single relations help you fetch data from the related collections.

To illustrate how it works, let's imagine we have the Transactions table that doesn't contain a customer's email and the Users table that contains the customer information including the email:

And we want to display the email in the Transactions list:

First of all, we identify how our tables are related: for each user, there are several transactions that are related to the users list by the ID and Customer ID fields:

Now, let's create a new custom column in the Transactions table:

Then change the column type to Link to record

Now, we need to select where we'll get the user email from (a related Users table), what field in the Users table is used to set relations with the Transactions table (the ID field), and what field from the Users table we'd like to display (the Email field):

And the final step is to get our custom field value from the Transactions table field that sets relations to the Users table (the Customer ID field):

Now, let's make UI components dynamically visible based on a rule:
