    <p>Let's suppose I have a Core Data model using <code>AFIncrementalStore</code>, and I have multiple REST API endpoints for retrieving a list of objects of that model. I can override <code>-requestForFetchRequest:withContext:</code> in <code>AFHTTPClient</code> like so:</p> <pre><code>- (NSURLRequest *)requestForFetchRequest:(NSFetchRequest *)fetchRequest withContext:(NSManagedObjectContext *)context { NSMutableURLRequest *mutableURLRequest = nil; if ([fetchRequest.entityName isEqualToString:@"Post"]) { mutableURLRequest = [self requestWithMethod:@"GET" path:@"/posts/foo" parameters:nil]; } return mutableURLRequest; } </code></pre> <p>In this snippet, I retrieve <code>Post</code> objects at <code>/posts/foo</code>, but I also need to retrieve another set from <code>/posts/bar</code>. </p> <p>How can I do this? The only solution I see is to make two models: one for <code>foo</code> and one for <code>bar</code>, but repeating yourself is lame, and there may be many more API endpoints that get <code>Post</code> objects for me that I'll need to support. Is there some other approach that I'm missing?</p>

    1. COHow do you decide if you want `/posts/foo` or `/posts/bar`? For example, are those Post objects by different users? Can you inspect `fetchRequest` to determine whether you're currently looking for `foo` or `bar` posts?

    2. COIn my case, the API I'm talking to has a screen where I need to request both Foo and Bar Posts to list in a single table view. My post model does have a property indicating which type it is, so perhaps I could look at `fetchRequest.predicate.predicateFormat` and determine that way?

    3. COYeah, it sounds like in your case, you need to inspect `fetchRequest` more closely than just looking at `entityName`. You can also look at `fetchRequest.propertiesToFetch` or possibly other things depending on your data model. You'll still need to send two requests, so just make sure it can tell the difference.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
