Dynamic Data Manager node lets you manage the data that you want to store.
You have the following options:
Model
You can choose the schema from this drop-down.
Action
Choose an action from the drop-down that you want to perform on the schema.
Read
Based on the parameters given in the payload, the Dynamic Data Manager node will fetch the data.
In the previous image, the Dynamic Data Manager node will fetch all the data items from the Project.
“limit” specifies the number of data items to be shown per page in the result object. The maximum value is 999.
“page” is the page number to be shown in the results object.
“sortBy” is used to sort the fetched data based on the criteria.
For example, {"sortBy":{"modifiedAt":-1}} will sort the data items shown in the result array based on the modified date displaying the latest modified data item first.
The following image shows the result payload.
You can identify a data item using the ID or the Item Name. You can use either of them to get the data item in the Dynamic Data Manager node.
The ID is unique for a data item. You will get only one result when you use the correct ID.
Item Name is asked while creating the Data item manually. Multiple data items can have the same item name. You can query the data using the item name.
Create
Lets you create a new data item. If you don’t specify a project ID in the payload, the data is created as Global data.
As shown in the following image, the payload may contain hard-coded values or mustache tags. Data in the mustache tag is converted to a string while saving the data.
To avoid encoded or Unicode characters getting saved, place an ampersand (&) in the mustache tag.
Creating multiple data items
You can create multiple data items at the same time in two ways.
Place multiple objects in an array. In the following image, an array with two data items is given in the payload of the Dynamic Data Manager node.
Create an array in the function node placed before the Dynamic Data Manager node. The following code lets you create a sample array and store it in msg.payload.data.
var _ = global.get('lodash');
var sample = [
{
SampleText : "Google",
SampleURL : "https://www.google.com/"
},
{
SampleText : "Amazon",
SampleURL : 'https://www.amazon.com/'
}
];
_.set(msg,'payload.data',sample);
When using this method to create multiple data items, the payload in the Dynamic Data Manager node should be left empty.
Update
If the field is available in the schema, the content of that field will be updated with the content given in the payload. The _id is used to identify the data item (required). The field that you want to update must be inside the data object. For example, in the following image, hospitalCounty is a field available in the schema that will be updated with the data “county”.
Upsert
If multiple results are found for a query, the oldest data item gets updated.
Queries fields are available
If the queried fields are available, the schema fields are updated with the content given in the payload. In the following example, queried fields are available, but one of the payload properties is not available in the schema. NewField is not available in the schema. Except for NewField, all the other fields will be updated based on the payload.
Alternatively, you can create an array in the function node placed before the Dynamic Data Manager node to send the data to msg.payload.data.

When using this method to create multiple data items, the payload in the Dynamic Data Manager node should be left empty.
Queried fields are not available
If the queried fields are not available, it creates a data item and update the available fields in the schema based on the payload. For example, the following image shows the Newquery is not available as a field in the schema. Therefore, a new data item with a new id will be created with the payload.
Delete
You can Delete the data using a query. If the query matches multiple Data items, each of them is deleted.
Payload
A Function node should be placed prior to the Dynamic Data Manager node to verify the mandatory fields of the schema (model). These schema fields will be saved/queried based on the details given in this payload field of the Dynamic Data Manager node.
The output for the Dynamic Data Manager node will be in the msg.data object.
