I'm trying to use mvcmailer in my mvc web app. When I used it in a dummy project and continued the steps stated in the wiki, it worked fine and I was able to send an email.
But when I tried to integrate it in my web app, its giving an error at "PopulateBody(mailMessage, viewName: "Welcome");" stating that it is unable to find _Layout.text. _Layout.text.cshtml and _Layout.cshtml exists in Usermailer folder along with Welcome.cshtml.
Usermailer code
public class UserMailer : MailerBase, IUserMailer
{
public UserMailer():
base()
{
MasterName="_Layout";
}
public virtual MailMessage Welcome(string email, string validationUrl)
{
var mailMessage = new MailMessage{Subject = "Welcome to GiftSocial"};
mailMessage.To.Add(email);
ViewBag.Validationkey = validationUrl;
PopulateBody(mailMessage, viewName: "Welcome");
return mailMessage;
}
}
Controller code
UserMailer.Welcome(email: model.Email, validationUrl: validationUrl).Send();
Copied exception Details:
System.Web.HttpException was unhandled by user code

The error is pretty much self-explanatory. The required views were not found.
It seems that you were trying to send text/plain mail message. Therefor MvcMailer was looking for such views.

I am new to Sitecore,SoleNet. I have installed and configured Solr to work with Sitecore and I am able to see results.
I am now using code.
I added the connection string to UnityMVCActivator.cs in the Start()
Startup.Init("http://localhost:8983/solr/sitecore_web_index");
In my controller - Actionresults Index()
var solr = ServiceLocator.Current.GetInstance>();
I get this error

Any help is greatly appreciated.
Thank you!
Edit: this thread was also raised in GitHub in SolrNet and the project maintainer provided the right answer.
The problem is that for registering he is using the built in IoC but then resolving via Unity.
Original response
I may be reading your code wrong or something might be missing from the post but you are not passing the type:
In my controller - Actionresults Index()
var solr = ServiceLocator.Current.GetInstance<[you are missing this part]>();
When using generics you need to specify the type. I thinks this part would not even compile because of the .GetInstance>() being incomplete.
I'm using Postal library for sending emails in an ASP.NET MVC5 Web project. It works fine when called from a controller. However, I planned a number of jobs to send emails using fluentScheduler. And I am calling a method that sends emails using the instructions here http://aboutcode.net/postal/outside-aspnet.html.
But I still get the same exception everytime I run the background task.

I have no such errors locally. Here is where I invoke MvcSiteMap().SiteMapPath() method:
May be somebody had the same problem before. If so please share your solution.
Thanks in advance.
This won't answer your question directly, but may help you on your path to debugging the issue, seeing as it happens only in production and not in dev/debug.
Consider replacing your line:
#Html.MvcSiteMap().SiteMapPath()
With something like:
#SafeBreadCrumb()
#helper SafeBreadCrumb() {
MvcHtmlString output;
try
{
output = Html.MvcSiteMap().SiteMapPath();
}
catch (Exception e)
{
output = new MvcHtmlString(e.Message);
}
<text>#output</text>
}
Feels a little dirty, but it's easier than grabbing the source of MvcSiteMapProvider and sticking in some logging! If it happened in debug, you wouldn't need to try this. Plus it's just a view change, so won't need a recompile.
Based on the great answer at multi-step registration process issues in asp.net mvc (splitted viewmodels, single model), I used the example Darin Dimitrov provided to test out an ASP.net MVC3 wizard. It works standalone, but not inside Orchard CMS v1.3.
I am getting the following error:

I am venturing a guess that it's the controller that's causing a fuss. Here is the code:
[Themed]
public class WizardController : Controller
{
public ActionResult Index()
{
var wizard = new WizardViewModel();
wizard.Initialize();
return View(wizard);
}
[HttpPost]
public ActionResult Index([Deserialize] WizardViewModel wizard, IStepViewModel step)
{
wizard.Steps[wizard.CurrentStepIndex] = step;
if (ModelState.IsValid)
{
if (!string.IsNullOrEmpty(Request["next"]))
{
wizard.CurrentStepIndex++;
}
else if (!string.IsNullOrEmpty(Request["prev"]))
{
wizard.CurrentStepIndex--;
}
else
{
// TODO: we have finished: all the step partial
// view models have passed validation => map them
// back to the domain model and do some processing with
// the results
return Content("thanks for filling this form", "text/plain");
}
}
else if (!string.IsNullOrEmpty(Request["prev"]))
{
// Even if validation failed we allow the user to
// navigate to previous steps
wizard.CurrentStepIndex--;
}
return View(wizard);
}
}
But I am not 100% sure, and the other culprit could be the WizardViewModel:
[Serializable]
public class WizardViewModel
{
public int CurrentStepIndex { get; set; }
public IList<IStepViewModel> Steps { get; set; }
public void Initialize()
{
Steps = new IStepViewModel[]
{
new Step1ViewModel(),
new Step2ViewModel(),
new Step3ViewModel()
};
}
}
That last part is a manual insertion of the steps and alters the code originally posted (direct from author). Any help is greatly appreciated.
Apparently, the Model Binder you are using can't find the model it needs to instantiate from the supplied interface (IStepViewModel)
I am quite sure that the default ASP.NET MVC ModelBinder can't do such thing, as it would require some custom logic to choose the concrete interface implementation that should be instantiated.
Therefore, you have two solutions:
Check your sample, I think it provides a custom ModelBinder, and register it in Orchard by implementing an IModelBinderProvider
Don't ask for a IStepViewModel in the Index action:
public ActionResult Index([Deserialize] WizardViewModel wizard, IStepViewModel step)
And replace it with a concrete class.
I am intermittently getting an System.InvalidCastException: Specified cast is not valid. error in my repository layer when performing an abstracted SELECT query mapped with LINQ.
The error can't be caused by a mismatched database schema since it works intermittently and it's on my local dev machine.
Could it be because StructureMap is caching the data context between page requests? If so, how do I tell StructureMap v2.6.1 to inject a new data context argument into my repository for each request?
Update: I found this question which correlates my hunch that something was being re-used. Looks like I need to call Dispose on my injected data context. Not sure how I'm going to do this to all my repositories without copypasting a lot of code.
Edit: These errors are popping up all over the place whenever I refresh my local machine too quickly. Doesn't look like it's happening on my remote deployment box, but I can't be sure.
I changed all my repositories' StructureMap life cycles to HttpContextScoped() and the error persists.
Code:
public ActionResult Index()
{
// error happens here, which queries my page repository
var page = _branchService.GetPage("welcome");
if (page != null)
ViewData["Welcome"] = page.Body;
...
}
Repository:
GetPage boils down to a filtered query mapping in my page repository.
public IQueryable<Page> GetPages()
{
var pages = from p in _db.Pages
let categories = GetPageCategories(p.PageId)
let revisions = GetRevisions(p.PageId)
select new Page
{
ID = p.PageId,
UserID = p.UserId,
Slug = p.Slug,
Title = p.Title,
Description = p.Description,
Body = p.Text,
Date = p.Date,
IsPublished = p.IsPublished,
Categories = new LazyList<Category>(categories),
Revisions = new LazyList<PageRevision>(revisions)
};
return pages;
}
where _db is an injected data context as an argument, stored in a private variable which I reuse for SELECT queries.
Calling code:
public Page GetPage(string slug)
{
return _pageRepository.GetPages()
.WithSlug(slug).FirstOrDefault();
}
WithSlug is just a pipeline filter that adds a where clause to the query.
