Hi,

You can create records in any Odoo model using the JSON-RPC API. This method allows you to call any function on any model programmatically.

Basic Structure

The general structure for creating records is:

json

{

  "jsonrpc": "2.0",

  "method": "call",

  "id": 3,

  "params": {

    "service": "object",

    "method": "execute_kw",

    "args": [

      "database_name",    // Your Odoo database name

      user_id,            // User ID (integer)

      "password",         // User password or API key

      "model.name",       // Technical name of the model

      "create",           // Method to execute

      [

        [

          {

            "field1": "value1",

            "field2": "value2",

            // ... more fields

          },

          // ... more records

        ]

      ]

    ]

  }

}

Example: Creating Timesheet Records

Here's a practical example showing how to create multiple timesheet entries:

json

{

  "jsonrpc": "2.0",

  "method": "call",

  "id": 3,

  "params": {

    "service": "object",

    "method": "execute_kw",

    "args": [

      "fresh_test",             // Database name

      2,                        // User ID

      "1",                      // Password

      "account.analytic.line",  // Timesheet model

      "create",                 // Create method

      [

        [

          {

            "name": "Development Task",

            "project_id": 1,

            "task_id": 1,

            "employee_id": 1,

            "unit_amount": 8.0,

            "date": "2024-05-27"

          },

          {

            "name": "Testing and QA",

            "project_id": 1,

            "task_id": 2,

            "employee_id": 1,

            "unit_amount": 4.0,

            "date": "2024-05-27"

          },

          {

            "name": "Code Review",

            "project_id": 2,

            "task_id": 3,

            "employee_id": 2,

            "unit_amount": 2.0,

            "date": "2024-05-27"

          },

          {

            "name": "Documentation",

            "project_id": 2,

            "task_id": 4,

            "employee_id": 2,

            "unit_amount": 3.0,

            "date": "2024-05-27"

          },

          {

            "name": "Client Meeting",

            "project_id": 1,

            "employee_id": 1,

            "unit_amount": 1.5,

            "date": "2024-05-27"

          }

        ]

      ]

    ]

  }

}

Hope it helps
