    filtering nodes by UrlSegment instead of ID

    I have a 'story category' document type and a 'story' document type. Users can attach story categories to created stories via Contentful Data List property name 'categories'.

    I'm outputting these stories via a Block Grid element. By default, all stories will show up. But if the url has a query parameter (Ex: ?cat=url-segment), then I'd like to output a filtered view where the 'cat' parameter matches stories that have story category with a matching UrlSegment. I'm not receiving any errors, but nothing is outputting however when I using the following code.

    I'm brand new to Umbraco and .net core, so I appreciate what a great resource this community has been so far.

    var currentPage = HttpContextAccessor.HttpContext.Request.Query["cat"];

var stories = 
    Umbraco.ContentAtRoot().DescendantsOrSelfOfType("Story")
        .Where(x => x.IsVisible())
        .Where(x => x.HasValue("categories") && x.Value<IEnumerable<IPublishedContent>>("categories")
        .Select(y => y.UrlSegment)
        .Equals(currentPage))
        .OrderByDescending(x => x.Value<DateTime>("date"))
        .Take(10);

    If I use the story category ID as the cat parameter instead of UrlSegment and change the code to the following, it works. But I would prefer to match by UrlSegment if possible.

    Select(y => y.Id)
        .Contains(currentPage))

    Hi utiilityLA

    When you have the working filtering your code is

    Select(y=>y.Id)

    this would result in an IEnumerable of Ids

    and your contains clause checks if it contains the current Id

    ...

    but in your example for UrlSegment

    you have

    .Select(y => y.UrlSegment)

    wouldn't that result in an IEnumerable of strings for each UrlSegment?

    and so that would never equal a string category?

    also wondering if Any is what you need? I'm typing this on a phone but something like this:

     Umbraco.ContentAtRoot().DescendantsOrSelfOfType("Story")
        .Where(x => x.IsVisible() && x.HasValue("categories") && x.Value<IEnumerable<IPublishedContent>>("categories")
        .Select(y => y.UrlSegment).Any(f=>f.Equals(currentPage))
        .OrderByDescending(x => x.Value<DateTime>("date"))
        .Take(10);

    regards

    marc

    Thanks Mark for your response. It makes sense that an IEnumerable of strings would not match a single string.

    Your suggestion of using "Any" worked great! Thank you for pointing me in the right direction.
