❔ Viewing List from ViewBag

I'm not sure what to cast to make the result in ViewBag.CardsReturned usable in the view. (Sorry if this was a load of unnecessary information) Method creating the ViewBag:

        public async Task<IActionResult> Search(string searchString)
        {
            ICardService service = serviceProvider.GetCardService();
            var result = await service.Where(x => x.Name, searchString).AllAsync();
            ViewBag.CardsReturned = result;
            return View();
        }

        public async Task<IActionResult> Search(string searchString)
        {
            ICardService service = serviceProvider.GetCardService();
            var result = await service.Where(x => x.Name, searchString).AllAsync();
            ViewBag.CardsReturned = result;
            return View();
        }

What ICardService and AllSync are:

public interface ICardService : IMtgQueryable<ICardService, CardQueryParameter>
    {
        //
        // Summary:
        //     Gets all the MtgApiManager.Lib.Model.Card defined by the query parameters.
        //
        // Returns:
        //     A MtgApiManager.Lib.Core.IOperationResult`1 representing the result containing
        //     all the items.
        Task<IOperationResult<List<ICard>>> AllAsync();

        //
        // Summary:
        //     Find a specific card by its multi verse identifier.
        //
        // Parameters:
        //   multiverseId:
        //     The multi verse identifier to query for.
        //
        // Returns:
        //     A MtgApiManager.Lib.Core.IOperationResult`1 representing the result containing
        //     a MtgApiManager.Lib.Model.Card or an exception.

public interface ICardService : IMtgQueryable<ICardService, CardQueryParameter>
    {
        //
        // Summary:
        //     Gets all the MtgApiManager.Lib.Model.Card defined by the query parameters.
        //
        // Returns:
        //     A MtgApiManager.Lib.Core.IOperationResult`1 representing the result containing
        //     all the items.
        Task<IOperationResult<List<ICard>>> AllAsync();

        //
        // Summary:
        //     Find a specific card by its multi verse identifier.
        //
        // Parameters:
        //   multiverseId:
        //     The multi verse identifier to query for.
        //
        // Returns:
        //     A MtgApiManager.Lib.Core.IOperationResult`1 representing the result containing
        //     a MtgApiManager.Lib.Model.Card or an exception.

Don't Use a viewmodel/DTO

Pobiega•3y ago

The proper solution is to use a viewmodel.

BigggMoustacheOP•3y ago

I glanced at the topic but I didn't understand

Pobiega•3y ago

buuut... (IOperationResult<List<ICard>>)ViewBag.CardsReturned or something should work oh its fairly simple. You make a new class that represents the data you want to send to your view then you just make an instance of that class, fill it with your data, and pass it to the View function

Angius•3y ago

1. Create a class/record 2. Give it the values you want to pass to the view 3. Pass it to the View() method 4. Declare the @model type in the view 5. ??? 6. PROFIT

BigggMoustacheOP•3y ago

lol so @Model EmptyClass like an actual model and not the instance from method

Angius•3y ago

var person = new Person {
    Name = nameService.GetName(),
    Age = ageRepository.GetAge()
};

return View(person);

var person = new Person {
    Name = nameService.GetName(),
    Age = ageRepository.GetAge()
};

return View(person);

@model Person

<h1>Person!</h1>
<h2>Their name is <strong>@Model.Name</strong></h2>
<h3>And they're <blink>@Model.Age</blink> years old!</h3>

@model Person

<h1>Person!</h1>
<h2>Their name is <strong>@Model.Name</strong></h2>
<h3>And they're <blink>@Model.Age</blink> years old!</h3>

BigggMoustacheOP•3y ago

when I tried to reference @model ICard I got a restriction I can't remember now I didn't make that it's a package

Angius•3y ago

Why an interface?

BigggMoustacheOP•3y ago

should I just use DTO with my own class to simplify things?

Pobiega•3y ago

yes

BigggMoustacheOP•3y ago

this is what I meant by making copies earlier I figured if I'm already getting a list, why make another but okay

Pobiega•3y ago

well lists are references you wont be copying the data

BigggMoustacheOP•3y ago

oh true It just felt dumb like I should be able to use what I have

Pobiega•3y ago

just have a public record MyViewDto(List<Whatever> MyList); dont use viewbags. they are dynamic, untyped garbage

BigggMoustacheOP•3y ago

lmao yeah so I've read. Do I have to make like, whole copy of thing, or can I just do that one line in my method?

Pobiega•3y ago

you'll need to declare the record outside your method

BigggMoustacheOP•3y ago

The only time I did DTO was with Automapper tutorial xD okay

Pobiega•3y ago

so it can be "seen" from the view

BigggMoustacheOP•3y ago

Yeah duh

Pobiega•3y ago

look at ZZZZs post above

BigggMoustacheOP•3y ago

well also one more question (I will scroll back up in one second

BigggMoustacheOP•3y ago

They have a Card model in the package, but it has other interface / class dependencies inside of it

BigggMoustacheOP•3y ago

I'm not sure how I would handle these idk, different layers I'm guessing easiest would be to just make my own class, DTO what I need, and forget the rest?

Angius•3y ago

Generally speaking, you have one database model class, and however many DTOs you need The database class never gets exposed through the API

BigggMoustacheOP•3y ago

right

Angius•3y ago

Not sure what's what here, but I can assume that Card is analogous to a database model..? Regardless, you'd still want a DTO for your view

BigggMoustacheOP•3y ago

yes and ICard referenced earlier, that ICardServices gets lists of

Okay I hear you thanks for that so no matter what I need to make another class I'll just do exactly as you've said xD tyvm

Pobiega•3y ago

dont be afraid of making classes 🙂

BigggMoustacheOP•3y ago

Thanks a lot you two. Feel like I'm leveling up lately being able to navigate the litany of questions that pop up and you folks over here deserve lots of credit for it.
