我需要一些帮助,我一直在到处寻找为什么这种情况不断发生。我基本上有 2 张桌子,公司和地址。一家公司可以有多个地址。我的类和表如下所示
表格:
create table Company (
companyid int PRIMARY KEY IDENTITY not null,
name varchar(100),
agencyref varchar(20),
website varchar(100),
phoneno varchar(20),
faxno varchar(20),
modified datetime DEFAULT (GETDATE())
);
create table Address (
addressid int PRIMARY KEY IDENTITY not null,
companyid int null, //Does the same if set to not null
addressLine1 varchar(100),
addressLine2 varchar(100),
city varchar(50),
county varchar(100),
postcode varchar(10),
modified datetime DEFAULT (GETDATE()),
foreign key ( companyid ) references Company (companyid)
);
课程
public class Company
{
[Key]
[HiddenInput(DisplayValue = false)]
public int companyid { get; set; }
[DisplayName("Company Name:")]
public string name { get; set; }
[DisplayName("Client Reference:")]
public string agencyref { get; set; }
[DisplayName("Website Address:")]
public string website { get; set; }
[DisplayName("Phone No:")]
public string phoneno { get; set; }
[DisplayName("Fax No:")]
public string faxno { get; set; }
private DateTime _modified = DateTime.Now;
[DataType(DataType.DateTime)]
public DateTime modified
{
get { return _modified; }
set { _modified = value; }
}
public virtual ICollection<Address> Address { get; set; }
}
public class Address
{
[Key]
[HiddenInput(DisplayValue = false)]
public int addressid { get; set; }
[DisplayName("Address Line 1:")]
public string addressline1 { get; set; }
[DisplayName("Address Line 2:")]
public string addressline2 { get; set; }
[DisplayName("City:")]
public string city { get; set; }
[DisplayName("County:")]
public string county { get; set; }
[DisplayName("Postcode:")]
public string postcode { get; set; }
private DateTime _modified = DateTime.Now;
[DataType(DataType.DateTime)]
public DateTime modified
{
get { return _modified; }
set { _modified = value; }
}
public virtual Company Company { get; set; }
}
我的模型构建器
modelBuilder.Entity<Company>().HasMany(c => c.Address).WithOptional(p => p.Company).Map(c => c.MapKey("companyid"));
我一直在使用 Code First,并且数据库已经存在。我从数据库中得到的结果是:
公司表:
companyid name agencyref website phoneno faxno modified
4 erg NULL NULL NULL NULL 2012-12-20 13:20:56.430
地址表:
addressid companyid addressLine1 addressLine2 city county postcode modified
2 NULL hkjh NULL NULL NULL NULL 2012-12-20 13:50:37.977
如您所见,我希望地址表中的 companyid 填充为 4,但由于某种原因,这不是这样做的。
想知道是否有人可以帮助我解决这个令人沮丧的问题。我认为使用附加到视图模型的视图很简单,它返回两个填充有数据的类,然后将其插入数据库:
我的 clientModel 类既好又简单:
public class ClientModel
{
public Company Company { get; set; }
public Address Address { get; set; }
}
我对控制器的看法是:
[HttpPost]
public ActionResult Edit(ClientModel client)
{
// CompanyAddress ca = new CompanyAddress();
Domain.Data.EFDbContext context = new Domain.Data.EFDbContext();
if (ModelState.IsValid)
{
context.Companies.Add(client.Company);
context.Addresses.Add(client.Address);
context.SaveChanges();
return RedirectToAction("Index");
}
else
{
return View(client);
}
}
这就是我的编辑页面包含
@model TimesheetMVC.WebUI.Models.ClientModel
(包含在 FormMethod.Post 中)
<fieldset>
<legend>Company Details</legend>
<div class="editor-label">
@Html.LabelFor(model => model.Company.name)
</div>
<div class="editor-field">
@Html.EditorFor(model => model.Company.name)
@Html.ValidationMessageFor(model => model.Company.name)
</div>
<div class="editor-label">
@Html.LabelFor(model => model.Company.agencyref)
</div>
<div class="editor-field">
@Html.EditorFor(model => model.Company.agencyref)
@Html.ValidationMessageFor(model => model.Company.agencyref)
</div>
</fieldset>
<fieldset>
<legend>Address Details</legend>
<div class="editor-label">
@Html.LabelFor(model => model.Address.addressline1)
</div>
<div class="editor-field">
@Html.EditorFor(model => model.Address.addressline1)
@Html.ValidationMessageFor(model => model.Address.addressline1)
</div>
<div class="editor-label">
@Html.LabelFor(model => model.Address.addressline2)
</div>
<div class="editor-field">
@Html.EditorFor(model => model.Address.addressline2)
@Html.ValidationMessageFor(model => model.Address.addressline2)
</div>
<div class="editor-label">
@Html.LabelFor(model => model.Address.city)
</div>
<div class="editor-field">
@Html.EditorFor(model => model.Address.city)
@Html.ValidationMessageFor(model => model.Address.city)
</div>
<div class="editor-label">
@Html.LabelFor(model => model.Address.county)
</div>
<div class="editor-field">
@Html.EditorFor(model => model.Address.county)
@Html.ValidationMessageFor(model => model.Address.county)
</div>
<div class="editor-label">
@Html.LabelFor(model => model.Address.postcode)
</div>
<div class="editor-field">
@Html.EditorFor(model => model.Address.postcode)
@Html.ValidationMessageFor(model => model.Address.postcode)
</div>
