Re: Have userID in view, need userName posted

19-Dec-12 0:41

in my Get/Index view I am posting to my Post/Index method in the holidayController. So i am posting over the UserID, how can I use this to access the userName?

Iv tried

 public ViewResult Index(int userID, string userName)
        {
            Person person = new Person();
            //this assigns person.Id to the user Id
            person.Id = userID;
            //i want to assign name of person to the string userName
             userName = person.name;
}

This is flashing up cant be null for person.name?

Where is the user ID coming from? Do you have a database and a model (LINQ To SQL or EF)? If so, I believe you would just use a query to retrieve the Person entity where the ID matches the userID parameter. Then you could assign person.Name to the userName variable.

Hi,

try this:
public ViewResult Index(int userID, string userName)
{
Person person = new Person(userID);
//this assigns person.Id to the user Id
//person.Id = userID;
//i want to assign name of person to the string userName
userName = person.name;
}

and you should define the class Person with id:

public Person(int id)
{
//get the person from DB or ...
_name = "data from DB";
}

How to access 'name' given when user registers

Re: How to access 'name' given when user registers

18-Dec-12 22:52

So I only want the logged in user to be allowed to book holidays for them selves. I think the easiest way to do this is to compare 'name' of logged in user againast 'name' in person table. So....

public ActionResult Create()
        {           
            string xx = (string)Session["usernameID"];
            int? currentPersonID = Convert.ToInt32(xx);

            string userNameComparedAgainstLoginName = // here is where i want to say 'name' of logged in user

            CreateModel model = new CreateModel();
            model.currentPersonID = currentPersonID.Value;
            model.PList4DD = db.People.ToList();   
           

            if (userNameComparedAgainstLoginName == model.userName)
            {
                ViewBag.Id = new SelectList(db.People, "Id", "Name");
                return View(model);
            }
            else
            {
                TempData["canOnlyBookHolidaysForYourself"] = "I'm afraid you can only book holidays for yourself";
                return RedirectToAction("Index");
            }
        }

---------------------------------------

the name given when the user registers will be the same names used in the db.

So could someone tell me how I can access the logged in 'name'?

Thanks

sequence contains no elements

18-Dec-12 22:58

forgot to mention Its just the automatic login that comes with mvc3 razor

xnaLearner18-Dec-12 2:44

Re: sequence contains no elements

18-Dec-12 2:44

So a drop down is used to select the users name, then click 'view' and it will display all the holidays this user has previously booked.

From here the user can click 'create new' which will bring them to a create new page. Instead of having to re-select their name from another drop down i carried across the currentuserID and replaced the second drop down with the users ID.

Everything was working fine with 2 separate drop downs, the user could book holidays etc... However now (after I changed the second drop down to hold the ID value) I am getting an error from my listHoliday Method in my controller:

Error: InvalidOperationException was unhandled by the user code Sequence contains no elements

var dbPerson1 = (from p in db.People
where p.Id == PersonId
select p).Single();
Could anyone advise what to do? Im lost thanks for any replies.

First, make sure the proper set of ID values is actually being bound to the drop-down. Secondly, the "Single()" method will throw that exception if the query does not return any results. If it's possible that the "p.Id == PersonId" condition could yield ZERO results, use "SingleOrDefault()" instead, which will assign a null value to dbPerson1 if nothing is found with the query.

I'd say debug with a breakpoint and verify that, for one, the drop-down has the correct ID's assigned to it, and also that "PersonId" is capturing the correct value. Also, make sure that the "PersonId" does in fact exist in the "People" table.

hey matt...thanks for teh reply man that sorted it

What was the issue? Was the list not getting the correct values or did a "SingleOrDefault()" call take care of it?

[session] returns null

xnaLearner17-Dec-12 23:20

Im using a session variable to pass the user ID from the Index to the Create in the HomeController. ATM the user can use a drop down to select their name from the list of users and click 'View' to list the holidays they have previously booked. From there the user can click 'create' which will bring the user to a page which enables them to create a new holiday. From here they have to select their name again from the drop down list.

I want to store the users ID from the previous drop down so it will update automatically if they try to create another holiday (to replace the second drop down)

Im using a session variable to do this, iv put

Session["userameID"] = currentID;

in my view. Iv break pointed it just after and if I hold my mouse over 'currentID' it displays the correct ID of the user.

So iv tried to pass this down to the create method using

string xx = (string)Session["usernameID"];

However string 'xx' is returning NULL,., (tested with breakpoint)

I then placed the entire session in the view

Session["userameID"] = HolidayDate;

string xx = (string)Session["usernameID"];

and string 'xx' is still returning null.

Is it not meant to return the userID???

Thanks for any replys

I dont know whether this a typo in your question or is it bug in your code but

Session["userameID"] = currentID;

and this

string xx = (string)Session["usernameID"];

definitely dont match.

The spelling of the session key is different. one place it is userameID and another it is usernameID.

Twenty years from now you will be more disappointed by the things that you didn't do than by the ones you did do. So throw off the bowlines. Sail away from the safe harbor. Catch the trade winds in your sails. Explore, Dream. Discover.

I want to store the users ID from the previous drop down so it will update automatically if they try to create another holiday (to replace the second drop down)

Im using a session variable to do this, My View:

//this coverts the user ID to a string and stores it in

session["usernameID"]
string userID = currentPersonID.ToString();
Session["usernameID"] = userID;

-------------------------------------------------

//My Create:
//catches the session["UsernameID"], stores it in string 'xx'
//converts it to an int and stores it in currentPersonID
//then store the value of currentpersonID in the model

public ActionResult Create()
        {
        string xx = (string)Session["usernameID"];

        int? currentPersonID = Convert.ToInt32(xx);

        HolidayList model = new HolidayList();
        model.currentPersonID = currentPersonID.Value;

-------------------------------------------------
This all works fine, howeve how do I display the value properly in the view?
Where I was using :

HTML

@Html.DropDownListFor(model => model.PersonId, new SelectList(ViewBag.Id, "Value", "Text"),"---Select---") 
i've tried:

HTML

@Html.TextBoxFor(model =>model.currentPersonID, "currentPersonID")

//and

HTML

@Html.LabelFor(model =>model.currentPersonID)

hoping the correct ID would display, but only the text 'currentPersonID is displayed

please advise, thanks again

You try to get sessiondata in data format which you have stored like
if userid is integer then try to get data in integer only use type casting

Hi All,
I want to support multiple languages in my web application, here are few queries that I have
1) Do I need to install the fonts for those languages?
2) Using resource file will help me to change the images and text on the page for that language.
3) Is the Operating system involved anywhere in this process, e.g. if my application is being accessed by a person in China with a Chinese OS installed on his machine, will it affect?

Expecting your expert comments on the above.

Thanks & Regards,
Pramod

Thanks for your reply Rahul,
I tried the resource file approach but somehow the label text is not changing...
Is there something that I am missing?

I don't consider an expert myself, but I have some comments Smile | :)

1. Install WHERE? If you use web fonts or similar technique to display text on your site then yes, you need to have the fonts that support your languages. If you use one of standard fonts, then users have to have it installed on their machines.

2. Yes, resource files will help you but it is nowhere near the out-of-the box feature. Plan ahead and don't hardcode anything that can be different in other languages.

3. It depends. Not strictly the OS, but regional settings on user machine. Keep in mind that many elements may display differently especially if you what to parse user input. For example decimal separator may be '.'(dot) or ','(comma), currency symbol may be before or after amount and date formats are pure wild Smile | :)
