Question

我正在尝试使用

在新操作中的会话中为对象分配一个对象

using System;
using System.Collections.Generic;
using System.Collections.ObjectModel;
using System.Linq;
using System.Windows;
using System.Windows.Data;

namespace WpfApplication2
{
    public class ThingConverter : IValueConverter
    {
        public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
        {
            return new List<string>(((NamedThing)value).Name.Split(' '));
        }

        public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
        {
            return ((List<string>)value).Aggregate((s, ss) => s + " " + ss);
        }
    }

    public class NamedThing
    {
        public string Name { get; set; }
    }

    public class MYViewModel
    {
        public ObservableCollection<NamedThing> ThingsList { get; set; }

        public MYViewModel()
        {
            ThingsList = new ObservableCollection<NamedThing>
            {
                new NamedThing {Name = "Short"},
                new NamedThing {Name = "VeryVeryLongWord"},
                new NamedThing {Name = "Several Words in a Row"}
            };
        }
    }

    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();
        }
    }
}

$project = $this->userInput->getProject(); $this->view->assign('project', $project);显示标记为prototype，proxy和persistable的完整对象。所以我认为这有效......

但是表格没有填写项目中的内容。

<f:debug>{project}<f:debug>

这很奇怪，因为在编辑操作中我做的是同样的，它在那里工作..

    <f:form controller="mycontroller" action="create" class="form-horizontal" objectName="project" method="POST" enctype="multipart/form-data" additionalAttributes="{role:'form', novalidate:'true'}">

唯一的区别是，对象来自数据库中的存储库。

有什么想法吗？

好吧，我回答我自己的问题......我必须将对象属性object="{project}"放到这样的表单中：

<f:form action="update" objectName="project" object="{project}" class="form-horizontal" enctype="multipart/form-data" additionalAttributes="{role:'form', novalidate:'true'}">

从会话中获取元素并填写表单
