Issues with Adding User's Weight in Dashboard

[AaronHsiung]

Steps to Reproduce

1. Navigate to the dashboard.
2. Click "+" (add entry) in the weight section.
3. Enter "50" in the weight field.
4. Click anywhere within the module.
5. Observe the weight field turning red.
6. Submit the weight information.
7. Automatically navigate back to the dashboard and observe if the updated weight information is shown.
8. Manually refresh the dashboard and observe if the updated weight information is shown.

Expected results:

• When the user enters an acceptable number, the field should not turn red.
• A confirmation message should appear after submitting the weight information.
• The dashboard should update immediately to display the new weight.

Actual results:

• When entering "50" in the weight field, it turned red, indicating an error. Adding "kg" to the number resulted in an error message stating that only numbers are accepted. This behavior caused confusion as users might not immediately understand the acceptable format.

• No confirmation message appeared after submitting the weight information, leading to uncertainty about whether the input was successfully recorded.
• The dashboard required a manual refresh to display the updated weight information. The changes were only visible after refreshing the page, affecting the user experience.
