Using Camera Feature

What is Camera Feature

The web app utilizes the camera function built into the browser, allowing you to select a photo taken by the camera or a saved image on the web app, and upload the image. The uploaded image can be displayed in the CELF app.

Using Camera Feature

To use the camera feature, specify 'Camera' when setting the input/display method of columns during app customization. 'Camera' can only be specified for String type data. Image uploaded using the camera feature will be assigned a 'File ID', and this 'File ID' is set as the data value in the column where 'Camera' is specified for input/display method.

  • In master setup, the master column associated with the original table column cannot have 'Camera' specified as the input/display method. Other columns, including display columns, can be specified with 'Camera'.
  • In 'Related Table Settings', the related table column associated with the original table column cannot have 'Camera' specified as the input/display method. Other columns can be specified with 'Camera'.
