MVC3 - How to edit multiple instances of same model in edit view?

Jun 29, 2012 12:16 AM|LINK

My Clock class could have many ClockAction objects related to it. My view edit is using the ManageClocks controller so it can edit both Clock and ClockAction.
The edit view should allow to edit all ClockActions for a particulair Clock. The ClockActions will have a custom field name, ie "Update Firmware". Checking off the checkbox for this should create a ClockActions object with a specified clockType (based on the field).

My edit view will edit all the properties in the Clock model, but how do I create a ClockAction for each input field? Also, how do I specified clockType in the background per field?

public class Clock
	{
		public int ID { get; set; }
		public string SerialNumber { get; set; }
		public string FirmwareVersion { get; set; }
		public DateTime? LastActivityDate { get; set; }

                public virtual ICollection<ClockAction> ClockAction{ get; set; }
	}

    public class ClockAction
    {
        public int ID { get; set; }
        public int ClockID { get; set; }
        [ForeignKey("ClockID")]
        public virtual Clock Clock { get; set; }
        public string ActionCommandString { get; set; }
        public int ActionType { get; set; }
    }

    public class ManageClocks
    {
        public Clock ClockManageModel { get; set; }
        public ClockAction ClockAction { get; set; }

        public void ClockAndClockActionsView(Clock clockManageModel, ClockAction clockAction)
        {
            ClockManageModel = clockManageModel;
            ClockAction = clockAction;
        }

    }


Edit View

@model ClockServer.Models.ManageClocks

@{
    ViewBag.Title = "Edit";
}

<h2>Edit</h2>

<script src="@Url.Content("~/Scripts/jquery.validate.min.js")" type="text/javascript"></script>
<script src="@Url.Content("~/Scripts/jquery.validate.unobtrusive.min.js")" type="text/javascript"></script>

@using (Html.BeginForm())
{
    @Html.ValidationSummary(true)
    <fieldset>
        <legend>Clock</legend>

        @Html.HiddenFor(model => model.ClockManageModel.ID)

        <div class="editor-label">
            @Html.LabelFor(model => model.ClockManageModel.SerialNumber)
        </div>
        <div class="editor-field">
            @Html.EditorFor(model => model.ClockManageModel.SerialNumber)
            @Html.ValidationMessageFor(model => model.ClockManageModel.SerialNumber)
        </div>
        <div class="editor-label">
            @Html.LabelFor(model => model.ClockManageModel.FirmwareVersion)
        </div>
        <div class="editor-field">
            @Html.EditorFor(model => model.ClockManageModel.FirmwareVersion)
            @Html.ValidationMessageFor(model => model.ClockManageModel.FirmwareVersion)
        </div>

        <div class="editor-label">
            @Html.LabelFor(model => model.ClockManageModel.LastActivityDate)
        </div>
        <div class="editor-field">
            @Html.EditorFor(model => model.ClockManageModel.LastActivityDate)
            @Html.ValidationMessageFor(model => model.ClockManageModel.LastActivityDate)
        </div>
        <p>
            <input type="submit" value="Save" />
        </p>
    </fieldset>
}

<div>
    @Html.ActionLink("Back to List", "Index")
</div>

Thanks for the link.

I changed my ManageClocks model to have a property which contains a collection of ClockActions. The only problem with the method described in the link is that when I pass the ManageClocks model to the edit view, it will not recoginize the ClockActions property as a collection. It will recognize model.ClockAction but not model.ClockAction[i].<property name>.

public class ManageClocks
    {
        public Clock ClockManageModel { get; set; }
        public ICollection<ClockAction> ClockAction { get; set; }
    }


  public ActionResult Edit(int id)
        {
            ManageClocks manageClocks = new ManageClocks();
            manageClocks.ClockManageModel = db.Clocks.Find(id);
            return View(manageClocks);
        }

Any way around this?
