Learning the design flow to add documents to Firestore in FBP
To add documents to Firestore using the FBP Firebase Plugin,
(1) First, create the document using a series of nodes provided by the plugin
(2) Add the document by using the “Add Document” node
Below is a sample workflow of adding a document.
Creating the Document
To add a document using the FBP Plugin, you will need to create the document first. To create the document, start with the "Begin Write Document" node.
To create the document, start with the "Begin Write Document" node.
Then, you can add data to it by calling these available nodes:
(1) Add String
(2) Add Number
(3) Add Boolean
(4) Add String Array
(5) Add Number Array
(6) Add Boolean Array
(7) Add Map
Adding the document
Once the document is created, use the Add Document node and connect the Document object returned by the last add node to the Document pin.
Then set the location of where to add it using the Document Path pin. Left click on the pin, hold, and drag to an empty space in the blueprint.
Type "Make" in the Search box and select "Make Array."
Every even element represents a collection, and every odd element represents a document. If no document id is specified, it will generate a unique id.
If we want to use a specific id, just add another element and provide the id.
Add the Callbacks
The Add Document function has 2 callback pins used to handle events after the operation is completed.
When the Document is added successfully, it will call the On Document Added callback and when it fails, it will call the On Fail to Add Document callback.
To create these callbacks, click and hold on the callback pin from the node. Then drag and let go on an empty spot on the blueprint.
Select “Add Event” then “Add Custom Event.” That will create the event node fit for the callback.
