Zend Framework 2＆Apigility - 将链接插入集合

Question

I have an Apigility resource with a patchList method. The method returns a collection. I need to set a link to another resource on the returned collection.

So, if a collection looks like this:

{
  _links: {
    self: '//foo.bar',
  },
  _embedded: {
    foo: []
  }    
}

I want it to be like so:

{
  _links: {
    self: '//foo.bar',
    bar: '//foo.bar/456'
  },
  _embedded: {
    foo: []
  }    
}

Now, I have read the docs, and I see how I can add a static link, but I need the link to be set dynamically. I think I might be able to achieve this by listening to the renderCollection event, but I was wondering if there is a simpler solution.

Answer 1

For single resources you can also use the EntityExtractor to add custom links to the LinkCollection, but for rendering a Collection such an extractor is not used so all you can do to add them dyamically is by using the renderCollection event like you already suggested in your question.
