How to log user mess attendance and view mess details

[adityabisht02]

1. For the mess details I need to return the menu for the day and the messcodes for the particular user.
2. For the mess attendance I need to log the attendance of the user who enters the code on the admin device.

Possible ways of achieving this:

1. I need to use the user id and not the user name for this so that duplicacy in names can be avoided.
2. I need a way to have access to the id of the current user at all times.

Using shared preferences in my app to store the name and id of the user could be a way to achieve this.

I have stored the userid in local storage of the android device. I am thinking I should design the messcodes according to the id. What I am thinking of doing is I'll not store the mess attendance anywhere, instead I'll just display a positive response on the admin side that the user exists and can have the meal.

In the future I can find a better way of managing mess attendance on the basis of only messcode with separate messcodes for breakfast, lunch , dinner and separate attendance for breakfast , lunch and dinner..
