Record Filtering With Nested Fields

Corteza doesn’t natively support filtering using values from referenced values, such as records and users.

Let us use an example where we have two modules: user and package where each user can have a package. We wish to find only the users that have a specific package.

You can use one of the following workarounds.

Clone the child fields into the parent

Extend the user module to add a new field, for example, filter__package_name. You can add additional fields if you wish to use multiple fields.

Define an automation with a before create/update trigger for the user module.

The automation fetches the related package of the user in question and populates the newly created filter__package_name field with the name field from the corresponding package record.

When searching for users, refer to the filter__package_name field.

Perform multiple fetches

This option only applies if you’re searching for records outside of the existing web applications.

Instead of performing one fetch, you can perform multiple fetches.

Firstly fetch the package records based on some query.

The response would look something like this:

[{
  "recordID": "1"
},
{
  "recordID": "2"
}]

Next, fetch the user records where the query limits the users only to the records obtained in the previous query.

To exemplify, the query would look like this:

`package='1' OR package='2'`
