Relations

Link forms together using relation fields to reference data across structures.

Relation field

The relationship field is a concept specific to Daxium-Air. It allows the user to select another form (then called sub-form) and link it to the one they are filling out. Once your relationship field is added to the form, choose the forms that will be linked from the Forms drop-down list.

Relationship field options:

Selection: attach an existing child submissions (broadcasted, assigned, searched, created on mobile)
- Manual: choose from a list of submissions
- Camera: Allows you to scan barcodes with your camera to select a child submission (Mobile only)
- External scan: Allows you to scan barcodes with an external scanner to select a child submission (Mobile only)
- NFC: See the section below
Creation: Create a sub-submission of the form
- Send child submission upon creation: If unticked, the child submissions will only be sent to the back office when you send the main submission. If ticked, the child submissions are sent as soon as they are created (Mobile only)
Edition for child submissions: Allows to edit an existing linked or created child submission
Allow multiple child submissions: add several child submissions to the main submission
Countable relation: allow a count for each child submission: Allows you to link a quantity for each of your child submission
Plan view: add a PDF or image file to edit it and attach child submissions to it
Visualisation: Allows you to choose different options to visualise the submissions in the relation field. You can configure distinct options for the web & mobile platforms to match your needs

NFC: Selecting a relation via NFC

Daxium-Air's NFC relation selection allows you to associate an NFC tag with a related submission (use cases: personnel, materials, equipment, etc.) in order to instantly select it in another form. This method replaces or complements manual search and QR codes, offering a faster, more reliable, and more secure approach.

Setting up NFC selection requires four steps:

Enable NFC tag search on the subform: allow the child form to be looked up by NFC.
Enable NFC selection on the relation field: activate the NFC option in the parent form's relation field.
Write a submission to an NFC tag: link a specific submission to a physical tag via the Admin NFC menu.
Use the tag in the field: scan the tag while filling in a submission to instantly select the linked record.

Step 1: Enable NFC search on the subform

Go to the relevant form (the one that will be called by another, e.g., Internal Signatory Form).

Open the form configuration.
Check "Allow NFC tag search from a parent relationship". Customize the NFC tag naming: select the fields used to clearly identify the submission (e.g., Status, First Name, Last Name).

Choose unique and easily readable fields (e.g., "Technician – First Name Last Name").

Enabling this option makes the form's submissions available for selection in the Admin NFC menu (step 3), each one listed under the name defined by the NFC tag naming fields above.

Step 2: Enable NFC selection in the parent form

From the parent form (the one that calls the relationship, e.g., Work Order or Service Request):

Access the Relation type field.
In the field options, check "NFC" in the Selection section.

This option allows you to select a submission via an NFC tag, without manual searching.

Step 3: Write a submission to an NFC tag

Once the forms are configured, you can associate your submissions with NFC tags.

In the Daxium-Air application, open the Admin NFC menu. If the menu is not present, add it from the custom app builder: Action = NFC Configuration.

The writable submissions appear in the list: these are the submissions of the form for which you enabled NFC tag search in step 1. Select the desired submission.

Tap Write on tag then bring a compatible NFC tag close to the smartphone.

The confirmation message appears: the tag is now linked to the submission.

You can filter submissions not yet written to a tag, and view the number of linked submissions per entry.

Step 4: Using the NFC tag in the field

When entering a parent submission, the relationship field (e.g., Authorized Person or Equipment concerned) can now be filled in by a simple NFC scan.
