title: Sending (nested) json object with file using Postman
body: <p>With Postman, I can attach files in requests with form-data, I can also send nested JSON object in raw format, but how can I do both: sending nested-structure data with file, e.g:</p>
  
  <pre><code>"data": {
      "normal_fields": {
          "field1": "value1",
          "field2": "value2"
      },
      "image_file": &lt;file&gt;
  }
  </code></pre>
