Hi! I want to create an app were a student will have to answer different questions which they will be saved in the database. However I want the teacher to know which student answered the questions.
I would like to ask if its possible to have a text input at the beginning of the app that will stay in the database and will show it each time the user answers a question. It will be something like a login page but i dont want to create a login page.
Are there any relevant tutorials?
Dear Emily,
You would need just a service that saves data in Database:

Hi Katya,
I decided to use the login/signup tutorial and create a sign up page.
I managed to connect my data and show which user inputs something in the database. However I cant figure out how to get the actual username to be shown. I can only see the user id numbers which are really long.
These are my mappings
I created a username local storage variable as well but when i connected it nothing was showing.
How do you save username to localstorage variable? Could you show us response mapping tab screenshot?
Hi Igor, thanks for the reply.
Here is the response tab. I didnt reallly do anything on it 
Hi Emily,
There is at least two ways to obtain a user name.
ol type="I"
liGet it by request to the user info(after loged on). Not recomended now cause of second way is easier. See details about this way here: http://docs.appery.io/documentation/b.../li
liStore userName on in the localStorageVariable on success login service event. To do it please follow steps below:/li
/ol
ol
liOpen your login service in data tab. http://prntscr.com/39sqap/direct/li
liCreate JS "success" event handler for your login service(datasource). And fill it with following code: http://prntscr.com/39sr4g/direct
precode
var userName = Appery("input_login").val();
localStorage.setItem("userName", userName);/code/pre/li
liNow you can use following code to get all current userName.
precode
localStorage.getItem("userName");/code/pre/li
/ol
Also you can map you LSV "userName" to the request field directly.
For this way please open mappings for your service.
Create localStorage variable. http://prntscr.com/39ss4y/direct
Mapp appearing LSV into your request parameter. http://prntscr.com/39ssic/direct
That's all.
Regards.
Thank you Illya!!!
