Create Orchard ContentItem programmatically from Command - orchardcms

I've written the following simple command inside my module. The Faq type has one custom part with a single field, and one BodyPart. After _cm.Create(item) is run, the item has an Id assigned but I can't find any trace of it in the database and it doesn't appear in Orchard's content tab. Why does the item get an Id but isn't found in the database? And does it need a driver, view, and placement info before it appears in the content tab?
public class ApiCommands : DefaultOrchardCommandHandler
{
private readonly IContentManager _cm;
public ApiCommands(IContentManager cm)
{
_cm = cm;
}
[CommandName("api seed")]
public void Seed()
{
var item = _cm.New("Faq");
item.As<FaqPart>().Question = "Why is the sky blue?";
item.As<BodyPart>().Text = "Shut up and do your homework.";
_cm.Create(item);
}
}
My custom part has no driver this is the Handler:
public FaqHandler(IRepository<FaqPartRecord> repository)
{
Filters.Add(StorageFilter.For(repository));
}

It turns out my type didn't attach a CommonPart. After I attached one and set the Owner property of the part, I was able to save it.

Orchard Core Cascade Delete

I have created a content item "Company" that has List Part of items "Offer".
When I delete Company all of it's Offers children are NOT being removed and leave no way to do it later (possibly manually in DB, but that's not the way I'd like to achieve it). Those items are still accessible in the customer user interface (Razor Page).
All of the above happens manually in the Orchard admin panel. I'm using decoupled cms mode.
Is there a possibility to get Orchard to do cascade delete on those items?
I’ve just prepared some fragment of code. Maybe it would be appropriate in your context. Firstly, you should create ContentPartHandler with ListPart as a generic type and override the RemoveAsync method. Then you can get all list items and remove them (as in the example below).
public class MyListPartHandler : ContentPartHandler<ListPart>
{
private readonly IOrchardHelper _orchardHelper;
private readonly IServiceProvider _serviceProvider;
public MyListPartHandler(IOrchardHelper orchardHelper, IServiceProvider serviceProvider)
{
_orchardHelper = orchardHelper;
_serviceProvider = serviceProvider;
}
public override async Task RemovedAsync(RemoveContentContext context, ListPart instance)
{
var items = await _orchardHelper.QueryListItemsAsync(instance.ContentItem.ContentItemId);
var contentManager = _serviceProvider.GetService<IContentManager>();
var tasks = items.Select(item => contentManager.RemoveAsync(item));
await Task.WhenAll(tasks);
}
}
Finally, you should register your handler in the ConfigureServices method of the Startup class.
services.AddContentPart<ListPart>().AddHandler<MyListPartHandler>();

Adding the target parameter to the Custom Link MenuItem in Orchard CMS

I have created my navigation menus in Orchard using a mix of Content Item and Custom Link Elements (parts of the website are outside the scope of the CMS). Now there are a couple of links that I need to open in a new window/tab, basically the target="_blank" behaviour.
SInce the original Custom Link does not have any parameters I tried to create an extended version of it. In the admin backend I went to "Content definition" looked up Custom Link and tried to create a copy of it, then add a target field that I could check for and use in my theme's Menu.cshtml file.
However I can't even get the basic carbon copy of the Custom Link item working. It has the same stereotype, same Parts, same Forms (none) as the original Custom Link, and it does appear in the list of items on the admin -> navigation window. However the item does not have a field for the URL/link. It only has the field for Menu Text, nothing else.
So my question is 2-tiered:
How can I get a carbon copy of the Custom Link item type working in my Orchard backend navigation?
When I have my copy of the Custom Link working and add a text field named target, how can I access its value in the Menu.cshtml view?
(I tried simply adding a URL field to my copy, that would then show up in the navigation editor, however the navigation itself would ignore it in the output and create a link to the content item id instead).
Any help is greatly appreciated!
Edit: Here are some screenshots to better illustrate the problem, maybe they can help pin down the problem.
Seems like you've done everything right. Please double check if MenuItemPart is there. This part is responsible for holding the URL information and displaying an editor for it. Not sure if this part is attachable though - if it's not, then make it so in the Content Definition\Parts pane.
Instead of hardwiring things inside Menu.cshtml, you should create a file named MenuItemLink-[YourTypeName].cshtml. This shape file will be used to display your custom menu items. Then you can access any fields via Model.Content object, eg. Model.Content.YourTypeName.FieldWithTargetName.Value.
You need to use the MenuItemPart because it has a few important functions integrated into Orchard.Core.
This works fine:
AdvancedMenuItemPartRecord:
public class AdvancedMenuItemPartRecord : ContentPartRecord
{
public virtual string Target { get; set; }
public virtual string Classes { get; set; }
}
AdvancedMenuItemPart:
public class AdvancedMenuItemPart : ContentPart<AdvancedMenuItemPartRecord>
{
public string Target
{
get { return Retrieve(x => x.Target); }
set { Store(x => x.Target, value); }
}
public string Classes
{
get { return Retrieve(x => x.Classes); }
set { Store(x => x.Classes, value); }
}
}
AdvancedMenuItemPartDriver:
public class AdvancedMenuItemPartDriver : ContentPartDriver<AdvancedMenuItemPart>
{
protected override string Prefix
{
get { return "AdvancedMenuItem"; }
}
protected override DriverResult Editor(AdvancedMenuItemPart part, dynamic shapeHelper)
{
return ContentShape("Parts_AdvancedMenuItem_Edit", () => shapeHelper.EditorTemplate(TemplateName: "Parts/AdvancedMenuItem", Model: part, Prefix: Prefix));
}
protected override DriverResult Editor(AdvancedMenuItemPart part, IUpdateModel updater, dynamic shapeHelper)
{
updater.TryUpdateModel(part, Prefix, null, null);
return Editor(part, shapeHelper);
}
}
AdvancedMenuItemPartHandler (ActivatingFilter add MenuItemPart to your AdvancedMenuItem dynamicaly):
public class AdvancedMenuItemPartHandler : ContentHandler
{
public AdvancedMenuItemPartHandler(IRepository<AdvancedMenuItemPartRecord> repository)
{
Filters.Add(StorageFilter.For(repository));
Filters.Add(new ActivatingFilter<MenuItemPart>("AdvancedMenuItem"));
}
}
Placement.info:
<Place Parts_AdvancedMenuItem_Edit="Content:11"/>
Migrations:
public int UpdateFrom2()
{
SchemaBuilder.CreateTable("AdvancedMenuItemPartRecord",
table => table
.ContentPartRecord()
.Column<string>("Target")
.Column<string>("Classes")
);
ContentDefinitionManager.AlterPartDefinition("AdvancedMenuItemPart", part => part

// We don't want our menu items to be draftable

);
return 3;

Customs binding cross views in mvvmcross

I need a custom binding and I know when and where but I don't know how I can do it. This is the relation of the view in my custom binding. Think about the *Views like controls.
I have the connections from ViewModel->ContainerView->FirstView but I can't connect it with the TableView. To connect the ContainerView to FirstView I did a custom binding (in one direction for now). And in the setvalue method I call the firstview's method SetBinding (where I want to do the binding)
I tried a few option but nothing happens, the last one looks like this:
public GolferList CurrentGolferList { get; set; }
public void SetBinding(GolferList golferList){
this.CurrentGolferList = golferList;
TableSource = new TableSourcePlayers(TableViewPlayers);
var bindingDescription = new[]{
new MvxBindingDescription {TargetName = "ItemsSource",SourcePropertyPath = "CurrentGolferList"} ,
};
Binder.Bind(this,TableSource, bindingDescription);
TableViewPlayers.Source = TableSource;
TableViewPlayers.ReloadData();
}
I would be grateful if you could tell me another way to handle it.
Update:
I followed Stuart's link and now it works fine, thanks a lot Stuart!
Actually, in my scheme the TableView is a MvxSimpleBindableTableViewSource and I want to bind the data there. So in order to make it work, I used the code below (SetBinding needs some external refactor):
private List<IMvxUpdateableBinding> bindings;
private string BindingText = "{'ItemsSource':{'Path':'CurrentGolfers'}}";
public object DataContext {
get { return dataContext; }
set { dataContext = value;
if (bindings == null)
bindings = this.GetService<IMvxBinder>().Bind(dataContext, TableSource, BindingText).ToList();
else
bindings.ForEach(b => b.DataContext = dataContext);
}
}
public void SetBinding(GolferList golferList){
this.DataContext = PlayViewModel;
tableView.Source = TableSource;
tableView.ReloadData();
}
Note that BindingText points to the table, not to the view itself.
Update 2
Now in V3 it's a bit different. First, the view must implement IMvxBindable and this members:
public object DataContext
{
get { return BindingContext.DataContext; }
set { BindingContext.DataContext = value; }
}
public IMvxBindingContext BindingContext { get; set; }
(Don't forget dispose calling BindingContext.ClearAllBindings() and also call to CreateBindingContext() in the viewload )
And then you'll be able to bind in your class. In my case:
var set = this.CreateBindingSet<FirstPlayViewController, PlayViewModel>();
set.Bind(source).To(vm => vm.CurrentGolfers).Apply(); //I love the new fluent api :)
I think what you want to do is actual a data-bound View, rather than a custom binding.
This is covered in this question - Custom bindable control in a MvvmCross Touch project
Basically what you need to do is to add a collection of 'Bindings' and the 'DataContext' property to your FirstView.
If you do that then you should be able to databind (to DataContext) within FirstView just like you do within any normal MvvmCross view.
Note - this will be much easier to do in v3 as we've added a 'BindingContext' object to assist with exactly this type of operation

Orchard CMS 1.4.2 - Edit view for my custom content type doesn't show content part data

Setup:
I am creating a module so that my clients can manage their own corporate emails as content.
The idea is to avoid putting people's real email addresses on a public website, so for a website user to send an email, I get Orchard to display a form. No problem with that. My problem (see below) is related to how Orchard displays content items in the dashboard, not the public facing part of the website.
Moving on:
I have created (see migration.cs below) a content type called EmailAddress. It is basically just a content type wrapper around a content part called CorporateEmailPart.
The other relevant bit of my setup is the driver (see CorporateEmailPartDriver.cs below). I have followed Kevin Kuebler's videos on PluralSight.com to write the driver. Debugging shows it working fine.
The shapes are placed using the Placement.info file in my module.
So, everything would be working fine if it wasn't for...
The Problem:
The driver correctly allows me to create the shape for the editor of my content type, which displays fine.
Or rather, displays fine to allow me to create a NEW EmailAddress. I can save the CorporateEmailPart to the database just fine.
However, when I save the new EmailAddress content type, or try to edit an existing one, the fields for the CorporateEmailPart don't display at all on my EmailAddress editor.
Ie, when in my POST DriverResult Editor method I return the GET Editor ContentShape, only the CommonPart of my Content Type is displayed (ie, the owner field of the ContentItem). No CorporateEmailPart data is displayed. Not even empty text boxes.
I must be missing something simple, cos everything else works.
But I just can't see what...!

EmailMessageSummaries = part.EmailMessages.Select(ue => ue.Summary).ToList()
};
}

}
}
Any suggestions much appreciated.
OK, a more careful debugging session with a clear mind and I found the issue:
An error is caused when building the viewmodel in my driver:
private CorporateEmailEditorViewModel BuildEditorViewModel(CorporateEmailPart part)
{
return new CorporateEmailEditorViewModel
{
Alias = part.Alias,
EmailAddress = part.EmailAddress,
DisplayOrder = part.DisplayOrder,
DisplayTitle = part.DisplayTitle,
IsDefault = part.IsDefault,
EmailMessageSummaries = part.EmailMessages.Select(ue => ue.Summary).ToList()
};
}
The offending line is:
EmailMessageSummaries = part.EmailMessages.Select(ue => ue.Summary).ToList()
The reason is that there is some problem with retrieving data from the EmailMessageRecord table using the CorporateEmailPartRecord_Id foreign key. I still haven't figured out what (have never used nHibernate which is what orchard uses), but the existence of this error answers the current question.
A Word of Advice:
Orchard works fine.
In fact, it works really well.
What doesn'twork is the code in your module.
So be more careful with your debugging.
Kevin Kuebler's videos are a great orchard learning resource.
When you refactor the name of something, double check to make sure they have ALL been changed.
Addendum:
I have found what was causing the hHibernate error: shoddy refactoring.
I originally called the project CompanyEmails, but then refactored everything to call it CorporateEmails. The only problem being, I didn't refactor everything, did I? There was still a CompanyEmailPartRecord_Id field on the EmailMessageRecord model class, whereas in the database, I had changed it to CorporateEmailRecordPart_Id. So, just another bug, just a failure to refactor properly.

ContentManager.Create does nothing

I am trying to build a service in Orchard that allows me to create content through a custom form on a page. The service and the content type definitions look fine to me, but somehow, eventhough I don't get any errors or other signs in the Orchard log files, creating new content using the IContentManager does nothing for me.
Parts involved
The controller accepting the form values
[HttpPost]
public ActionResult Create(CreateSopViewModel viewModel)
{
if(!ModelState.IsValid)
{
var shape = _shape.CreateContent();
shape.Header = _shape.Parts_Title(Title: "New item");
// Add the original fields to the shape.
shape.Title = viewModel.Title;
shape.Description = viewModel.Description;
shape.InitialComments = viewModel.InitialComments;
return new ShapeResult(this, shape);
}
// Store the new procedure in the database
_service.CreateContentItem(
viewModel.Title,viewModel.Description,viewModel.InitialComments);
// Redirect the user back to the homepage.
return Redirect("~/");
}
The service that contains the CreateContentItem method:
public void CreateContentItem(string title, string description, string initialComments)
{
// Initialize a new content item based on the SOP type
var customPart = _services.ContentManager.New<MyCustomPart>("CustomContentType");
customPart.Description = description;
customPart.Identifier = BuildIdentifier(title);
customPart.ContentItem.As<TitlePart>().Title = title;
_services.ContentManager.Create(customPart.ContentItem);
}
The content part + record
public class MyCustomPart: ContentPart<MyCustomPartRecord>
{
[Required]
public string Identifier
{
get { return Record.Identifier; }
set { Record.Identifier = value; }
}
[Required]
public string Description
{
get { return Record.Description; }
set { Record.Description = value; }
}
}
public class MyCustomPartRecord: ContentPartRecord
{
public virtual string Identifier { get; set; }
public virtual string Description { get; set; }
}
The migration
SchemaBuilder.CreateTable(typeof(MyCustomPartRecord).Name, table => table
.ContentPartRecord()
.Column<string>("Description")
.Column<string>("Identifier"));
ContentDefinitionManager.AlterPartDefinition("StandardOperationalProcedurePart", builder => builder
.Attachable(true));
ContentDefinitionManager.AlterTypeDefinition("CustomContentType", builder => builder
.DisplayedAs("Custom Content Type")
.WithPart("TitlePart")
.WithPart("MyCustomPart")
.Creatable(true));
Question
Again, I don't get any errors, not in the log and not in Visual Studio. However, my new content item doesn't get created or at least, I can't see it in the admin section of the site under Content.
What is going on and how can I debug this behavior?
I had a similar problem, which was solved when I used the overloaded Create method taking a VersionOptions enum value:
content.Create(customPart.ContentItem, VersionOptions.Published);
This should work even if the content item is not creatable, as mine isn't.
I had a similar issue. In my case the item did appear eventually, but not right away.
The solution for me was to do:
_contentManager.Flush();
I was having this issue, in my case it was that I actually had an error in the database (trying to put 100+ characters into a field that would only hold 100!).
I found the error I was getting (null id in Orchard.Indexing.Models.IndexingTaskRecord entry (don't flush the Session after an exception occurs) ), actually masked the issue. I had to go hunt in the logs to find the real problem.
So anyway, my advice is if you see that contentmanager.create seems to be doing nothing, and any errors don't seem to help, check the logs carefully. They can be found in the logs sub-folder of the appdata folder in the main Orchard.Web project. Because as I've found in the last 48 hours, often the answer is there.
