【问题描述】:
我正在尝试在我的 asp.net mvc 项目中编辑一篇文章。这是我创建项目时所做的:
public ActionResult Create(ArticleViewModel model)
{
if (ModelState.IsValid)
{
try
{
// Get the userID who created the article
User usr = userrepo.FindByUsername(User.Identity.Name);
model.UsernameID = usr.user_id;
repository.AddArticle(model.Title, model.Description, model.ArticleBody);
}
catch (ArgumentException ae)
{
ModelState.AddModelError("", ae.Message);
}
return RedirectToAction("Index");
}
return View(model);
}
在我的存储库中:
public void AddArticle(string Title, string Description, string ArticleBody)
{
item Item = new item()
{
item_title = Title,
item_description = Description,
article_body = ArticleBody,
item_createddate = DateTime.Now,
item_approved = false,
user_id = 1,
district_id = 2,
link = "",
type = GetType("Article")
};
try
{
AddItem(Item);
}
catch (ArgumentException ae)
{
throw ae;
}
catch (Exception)
{
throw new ArgumentException("The authentication provider returned an error. Please verify your entry and try again. " +
"If the problem persists, please contact your system administrator.");
}
Save();
// Immediately persist the User data
}
public void AddItem(item item)
{
entities.items.Add(item);
}
但现在我想编辑一篇文章,这就是我现在所拥有的:
public ActionResult Edit(int id)
{
var model = repository.GetArticleDetails(id);
return View(model.ToList());
}
[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult Edit(ArticleViewModel model)
{
if (ModelState.IsValid)
{
// Attempt to register the User
try
{
item Item = repository.GetArticleDetailsByTitle(model.Title);
Item.item_title = model.Title;
Item.item_description = model.Description;
Item.article_body = model.ArticleBody.
// HERE I NEED TO SAVE THE NEW DATA
return RedirectToAction("Index", "Home");
}
catch (ArgumentException ae)
{
ModelState.AddModelError("", ae.Message);
}
}
// If we got this far, something failed, redisplay form
return View(model);
}
如您所见,我检查了调整后的文本并将其放入“项目”中。但是我怎样才能把它保存在我的数据库中呢? (我存储库中的函数)
【问题讨论】:
-
您使用什么 ORM 将数据保存到数据库中?
-
我建议您使用存储库更新方法。看看这个:[stackoverflow.com/questions/6851147/…
