Dynamic entry_name based on type of child property

[svenhaack]

Hello Johnannes,

first of all I wanted to thank you personally for the serializer. We are using it successfully in 2 projects and really love it.

Currently I am facing a problem and hope to get help here in the group.

I have a user object in which I have stored favourite dishes of the users as a list.

An example:

<user firstname="John" lastname="Doe">
  <favourites>
	<pizzas>
	  <pizza name="Pizza Hawaii" />
	</pizzas>
	<pastas>
	  <pasta name="Lasagne" /> 
	</pastas>
  </favourites>
</user>

I need the favorite foods in a flat list now though, so in this case:

<favourites>
	<pizza name="Pizza Hawaii" />
	<pasta name="Lasagne" /> 
</favourites>

For this I implemented a getItems() method in my Favourites object instead of getPizzas()and getPastas(), which returns me dishes of type "Pizza" or "Pasta".

Now how can I implement that I can set the entry_name in the list depending on the child object.

My Favourites specification looked like this before:

pizzas:
  expose: true
  accessor:
    getter: getPizzas
  xml_list:
    entry_name: pizza
pastas:
  expose: true
  accessor:
    getter: getPastas
  xml_list:
    entry_name: pasta

The new specification now looks like this:

items:
  expose: true
  accessor:
  getter: getItems
  xml_list:
    entry_name: <pizza or pasta based on the type>

Pizza and Pasta object now has a "type" property storing "pizza" and "pasta", I did already exclude it in the child types because the structure here is given and it cannot be added as a new attribute type.

How can this be achieved?

Thanks for your help!

Best regards,
Sven

Hi @svenhaack !

I think inline option under xml_list will help you to achieve your goal.
