Razor - how to list descendants from multiple lists and multiple doc types

Razor

HI there,

Currently we use the following script to make lists of events document types no matter where they appear in the content tree. We have a new event doc type (alias RecruitmentEvent) and so we now need this list to pick up both doc types - Eventspage and RecruitmentEvent.

I've tried changinging this line

var newsEvents = root.DescendantsOrSelf("Eventspage").ToList();

to:

var newsEvents = root.DescendantsOrSelf("Eventspage||RecruitmentEvent").ToList();

but that didn't work so I must be missing something! This is the full script we currently have:

@using umbraco.MacroEngines
@inherits DynamicNodeContext
@{
    string tagToFind = Parameter.EventType;
    var root = Model.AncestorOrSelf(1);
 var newsEvents = root.DescendantsOrSelf("Eventspage").ToList();
        
       
        @foreach (var item in newsEvents.Where("startDateAndTime >= @0", DateTime.Now.Date).OrderBy("startDateAndTime"))
        {
            string[] tags = item.tags.ToString().Split(',');
          
           if (tags.Contains(tagToFind))
                {
                    
                   
      
          
           @if(@item.eventName.ToString() != string.Empty){
    @item.eventName

}else{
    @item.Name

}
           
           @item.startDateAndTime.ToString("dd MMM yyyy")

          @item.Summary

                 ›› Read more

      

 
   
                  }
         
                        }
 

         
}

Hi Clare,

What if you try to change:

var newsEvents = root.DescendantsOrSelf("Eventspage").ToList();

To this:

var newsEvents = root.DescendantsOrSelf().Where("NodeTypeAlias == @0 || NodeTypeAlias == @1", "Eventspage", "RecruitmentEvent").ToList();

So your full script would look like this.

@using umbraco.MacroEngines
@inherits DynamicNodeContext
@{
    string tagToFind = Parameter.EventType;
    var root = Model.AncestorOrSelf(1);
    var newsEvents = root.DescendantsOrSelf().Where("NodeTypeAlias == @0 || NodeTypeAlias == @1", "Eventspage", "RecruitmentEvent").ToList();
    
        
       <div>
        @foreach (var item in newsEvents.Where("startDateAndTime >= @0", DateTime.Now.Date).OrderBy("startDateAndTime"))
        {
          string[] tags = item.tags.ToString().Split(',');
          
           if (tags.Contains(tagToFind))
                {
                    
                   <div class="row">
        <div class="span8 @item.IsLast("no-border")">
            
           @if(@item.eventName.ToString() != string.Empty){
    <h3><a style="text-decoration:none" href="@item.Url">@item.eventName</a></h3>
}else{
    <h3><a style="text-decoration:none" href="@item.Url">@item.Name</a></h3>
}
           
           <p>@item.startDateAndTime.ToString("dd MMM yyyy")</p>
          <p>@item.Summary<br/>
                  ›› <a href="@item.Url" title="@item.HeaderText">Read more</a></p>
      </div>
   </div> 
                  }
         
                        }
 </div>
           
}

Hope this helps,

/Dennis
