In this API the filestore ID will be the ID the geoJson file which will be:

      "type":"name",
      "properties":{
         "name":"urn:ogc:def:crs:EPSG::3857"
      }
   },

}

Flow

1. Client Initiates Request:

   • The client initiates a dataGenerate request to the Project Factory Service.

2. Validation of Request:

   • Schema Validation: Validate against generateRequestSchema.

   • Tenant ID Validation: Ensure tenantId matches in query and RequestInfo.userInfo.

   • Force Update: Default to "false" if missing.

   • Hierarchy Type Validation: Validate hierarchyType for the tenantId.

3. Processing of Generate Request:

   • Fetch Data from DB:

     • Retrieve data using getResponseFromDb(request).

   • Modify Response Data:

     • Modify the fetched data with getModifiedResponse(responseData).

   • Generate New Entry:

     • Create a new entry with getNewEntryResponse(request).

   • Expire Old Data:

     • Update the status of old data to expired using getOldEntryResponse(modifiedResponse, request).

   • Persist Data Changes:

     • Call updateAndPersistGenerateRequest(newEntryResponse, oldEntryResponse, responseData, request).

       • Purpose:

         • If forceUpdate is true and data exists: Mark existing data as expired and create new data.

         • No data exists or force update is true: Generate new data.

         • If forceUpdate is false and data exists: Return the old data.

4. Boundary Data Processing:

   • Generate new Boundary Data:

     • Fetch Boundary Relationships.

     • If no boundary is found, generate an empty boundary sheet.

     • Fetch Filters from CampaignId and generate Boundary Data based on those filters.

       • If the filter is null, it will generate the whole Boundary Data.

   • After the Boundary Sheet has been generated, append the ReadMeSheet.

   • Generate different tabs based on any boundary level configured (here District).

5. Generating Different Boundary Templates based on Campaign Type

• Fetch configurable columns from mdms present for each campaign type from schema - (HCM-ADMIN-CONSOLE.adminSchema).

• Here is a sample data from the given schema having configurable columns for the SMC campaign:

```postman_json
 "Mdms": {
        "tenantId": "mz",
        "schemaCode": "HCM-ADMIN-CONSOLE.adminSchema",
        "uniqueIdentifier": "boundaryGeometryManagement.all",
        "data":{
                "title": "boundaryGeometryManagement",
                "$schema": "http://json-schema.org/draft-07/schema#",
                "properties": {
                    "numberProperties": [
                        {
                            "name": "HCM_ADMIN_CONSOLE_LAT",
                            "type": "number",
                            "isRequired": true,
                            "description": "Latitude",
                            "orderNumber": 2
                        },
                        {
                            "name": "HCM_ADMIN_CONSOLE_LONG",
                            "type": "number",
                            "isRequired": true,
                            "description": "Longitude",
                            "orderNumber": 3
                        }
                    ],
                    "stringProperties": [
                        {
                            "name": "HCM_ADMIN_CONSOLE_BOUNDARY_CODE",
                            "type": "string",
                            "isRequired": true,
                            "description": "Boundary Code",
                            "orderNumber": 1,
                            "freezeColumn": true
                        }
                    ]
                },
                "campaignType": "all"
            },
        "isActive": true
    }
```

1. Handle Error:

   • Update status to failed, add error details, log the error, and produce a message to the update topic.

2. Downloading the generated boundary template through /data/_generate API:

   • One can get the filestoreId through the /data/_download API which will fetch from db using the id from the response of /data/_generate API.

After successful generation, the sheet you will get from filestoreId will be:

147KB

BoundaryGenerationData.xlsx

Open

Boundary Generation Data

Note: The downloaded template will have one ReadMe sheet, one Boundary Data tab, and all other tabs on a number of unique districts (or whichever level is configured).
