I have a set of events that I created from a external data set. When syncing these events I need to see if this content is already exists based on the value of a property.
I have a document type with a properly EventId. Now I want to query through all content in a specific collection. And see if there already is content where the EventId matches my external event id.
private bool ContentExists(string searchString)
{
const int pageSize = 100;
var propertyAlias = MyDetailPage.GetModelPropertyType(i => i.Propety).Alias;
var collectionNode = _contentService.GetById(GetCollectionGuid()); // get Guid of the parent node, create method yourself
var pages = Convert.ToInt32(Math.Ceiling(_contentService.CountChildren(collectionNode.Id, MyDetailPage.ModelTypeAlias) / (float)pageSize)); // count the number of children for the parent node
if (pages <= 0)
{
return false; // if 0 zero it means there are no children
}
// umbraco only allows us to navigate through children paginated
for (var pageIndex = 0; pageIndex < pages; pageIndex++)
{
var children = _contentService.GetPagedChildren(eventCollectionNode.Id, pageIndex, pageSize, out _);
if (children.Any(i => i.GetValue<object>(propertyAlias).Equals(searchString, StringComparison.OrdinalIgnoreCase)))
{
return true;
}
}
return false;
}
