How to update AppDBContext in ASP.NET Core Web API - asp.net-core

Question

I am quite new to ASP.NET and I am bit stuck with this.
I am creating an entry in my DB while registering the user:
private async Task<bool> CreateEntryInUserActions(AppUser user)
{
var entity = new UserActionEntity
{
UserId = user.Id,
};
await _context.tbl_UserActions.AddAsync(entity);
await _context.SaveChangesAsync();
return true;
}
I want to change the IsPasswordChanged field in the UserActions table to true when a user changes his/her password.
I am trying something like:
private async Task<bool> UpdateUserAction()
{
var userId = _httpContextAccessor.HttpContext.User.FindFirst(ClaimTypes.NameIdentifier).Value; // gives me current user's id
var user = _context.tbl_UserActions
.Where(x => x.UserId.ToString() == userId).Select(x => x.IsPasswordChanged);
}
but I am not sure how to proceed and update this to "true". How do I update this entry?

You need to fetch the useraction entity from the table and then set the IsPasswordChanged property to true.
Try this:
private async Task<bool> UpdateUserAction()
{
var userId = _httpContextAccessor.HttpContext.User.FindFirst(ClaimTypes.NameIdentifier).Value; // gives me current user's id
var user = _context.tbl_UserActions.FirstOrDefault(x => x.UserId.ToString() == userId);
if(user != null) //check if the record is not null
{
user.IsPasswordChanged = true; // set the column to desired value
_context.tbl_UserActions.Update(user);
await _context.SaveChangesAsync();
}
}
