我正在(暂时)进行一个自学项目,创建一个会计软件包来管理客户、发票、估价等数据。
我现在在做客户系统。我知道如何设置应用程序以将不同的数据段存储在不同的列中,但我想学习如何将所有内容存储为JSON字符串。
[Table("Customers")]
public partial class CustomerDb
{
public int Id { get; set; }
public string Obj_Data { get; set; }
}
然后,我为各个数据段创建了一个客户模型:
public partial class Customer
{
public int Company_Id { get; set; }
public string Customer_Name { get; set; }
public string Customer_Company { get; set; }
public Dictionary<string, string> Phones { get; set; }
public List<Dictionary<string, string>> Emails { get; set; }
public string Terms { get; set; }
public Dictionary<string, string> Locations { get; set; }
public Dictionary<string, string> Preferences { get; set; }
public string Exemptions { get; set; }
}
添加新客户视图:
@model BSheets.Models.Custom.CustomerDb
@{
ViewBag.Title = "Add";
}
@using (Html.BeginForm())
{
@Html.AntiForgeryToken()
<div class="form-horizontal">
<h4>Customer</h4>
<hr />
@Html.ValidationSummary(true, "", new { @class = "text-danger" })
<div class="form-group">
@Html.LabelFor(model => model.Obj_Data, htmlAttributes: new { @class = "control-label col-md-2" })
<div class="col-md-10">
@Html.TextAreaFor(model => model.Obj_Data, htmlAttributes: new { @class = "form-control" })
@Html.ValidationMessageFor(model => model.Obj_Data, "", new { @class = "text-danger" })
</div>
</div>
<div class="form-group">
<div class="col-md-offset-2 col-md-10">
<input type="submit" value="Add" class="btn btn-default" />
</div>
</div>
</div>
}
<div>
@Html.ActionLink("Back to List", "Index")
</div>
@section Scripts {
@Scripts.Render("~/bundles/jqueryval")

在某种意义上,我设法做到了这一点:添加/更新客户信息的视图有一个TextArea,我只需在其中添加JSON字符串。然后,在Customer Index视图中,我将JSON字符串反序列化为Customer对象并显示各个Customer值。然后我创建了一个单独的应用程序,其中formfields使用HTML/JavaScript输出一个JSON字符串,我可以复制/粘贴到其中。
如果只是我在使用这个,那么粘贴在JSON字符串中也很好。假设我想为不同的用户设置我的应用程序,编辑一个缩小的JSON字符串是很麻烦的。
我想基于上面定义的客户模型创建一个视图,并从CustomerController向数据库提交一个JSON字符串。有人能给我指出正确的方向吗?谢谢。
