敏捷项目开源管理软件ScrumBasic（2）- 多项目支持

1.加入Project对象模型

public class Project
{
[Key]
[MaxLength(32)]
public string ID { get; set; }
public string Name { get; set; }
public int Order { get; set; }
public ICollection<UserStory> Stories { get; set; }
public ApplicationUser Creator { get; set; }
public DateTime CreateTime { get; set; }
public ApplicationUser Modifier { get; set; }
public DateTime UpdateTime { get; set; }
}

2.将Project关联到Story

public ICollection<UserStory> Stories { get; set; }

3.添加projectcontroller

遇到个bug：

warning CS0169: The field 'UserStoryController.mystr' is never used
System.Data.SqlClient.SqlException: Column 'Project.ID' is not the same length or scale as referencing column 'UserStories.ProjectID' in foreign key 'FK_UserStories_Project_ProjectID'. Columns participating in a foreign key relationship must be defined wit h the same length and scale.
Could not create constraint or index. See previous errors.
at System.Data.SqlClient.SqlConnection.OnError(SqlException exception, Boolean breakConnection, Action`1 wrapCloseInAction)
at System.Data.SqlClient.TdsParser.ThrowExceptionAndWarning(TdsParserStateObject stateObj, Boolean callerHasConnectionLock, Boolean asyncClose)
at System.Data.SqlClient.TdsParser.TryRun(RunBehavior runBehavior, SqlCommand cmdHandler, SqlDataReader dataStream, BulkCopySimpleResultSet bulkCopyHandler, TdsParserStateObject stateObj, Boolean& dataReady)

这是由于系统生成的代码不能识别外键字段长度导致。

fix it

migrationBuilder.AddColumn<string>(
name: "ProjectID",
table: "UserStories",
maxLength:32,
nullable: true);

启动。一切正常



　4. 下面来修改 Create New



删除 创建时间和更新时间，改由服务器赋值。

public async Task<IActionResult> Create(UserStoryViewModel userStoryViewModel)
{
if (ModelState.IsValid)
{
//mapping
UserStory usNew = map.Map<UserStory>(userStoryViewModel);
usNew.ID = Guid.NewGuid().ToString("N");
usNew.StatusCode = "Unstarted";
usNew.Creator = _userManager.FindByNameAsync(User.Identity.Name).Result;
usNew.CreateTime = DateTime.Now;
usNew.Order = _context.UserStories.Max(t => t.Order)+1;
_context.UserStories.Add(usNew);
await _context.SaveChangesAsync();
return RedirectToAction("Index");
}
return View("OK");
}

　　details 和index删除 createtime

5.menu加入project

6.加入ViewStrories Action

<a asp-action="ViewStories" asp-route-id="@item.ID">View Stories</a>

7.修改StoryController加入解析id　　



完成。
