Allow job/token name to be different than component name?

[imricardoramos]

Should the lib be able to send a batch request for the same component, but with different props?
Eg, I was trying to do the following request:

{
  "Job1": {
    "name": "MyComponent",
    "data": {
      "title": "Foo",
      "content": "foo"
    }
  },
  "Job2": {
    "name": "MyComponent",
    "data": {
      "title": "Bar",
      "content": "bar"
    }
  }
}

However, I can only do this:

html = renderer.render({
    'MyComponent': {
        'title': 'Foo',
        'content': 'foo'
    },
    'MyComponent': {
        'title': 'Bar',
        'content': 'bar'
    }
})

which makes the first job be overridden by the second job because they have same component name (https://github.com/ornj/hypernova-python/blob/master/hypernova/__init__.py#L53).

I've taken a quick look at the nodejs and the ruby clients, and it seems they do it differently:

In Ruby (https://github.com/airbnb/hypernova-ruby/blob/master/lib/hypernova/batch.rb#L45), they make an array of jobs, and then make a hash with the keys being the index of the job in the array.

In Node(https://github.com/airbnb/hypernova-node/blob/master/src/index.js#L89), they use the component name as the job name (as in this lib)

Hi @imricardoramos and thanks for the bug report (and additional research)! I will try to find the time the next couple of days to recreate the issue, will get back to you after that. Stay tuned :)

Thanks for your patience @imricardoramos. To first answer your question: No, it is currently not supported to retrieve more then one component per type in a batch request.

To add support for this we most likely need to change the internal data representation of the job queue to a list and introduce a feature for generating job ids.

Currently you have two choices:

• Cleaner api but not effective: Create your own abstraction on top of hypernova and implement the logic yourself (much like Guidance needed: how to call multiple versions of the same component? airbnb/hypernova-node#14).
• Kind of a hack but effective: You can also add metadata to the component name passed to hypernova, then while in hypernova you just remove it and continue as usual. Example: Pass the name “MyComponent.js#my-id”, then in your getComponent function in hypernova, drop the remaining #... part.

Going forward, I think taking a hard look at how the internal data representation are organized and how we can enable this functionality without breaking any api while keeping a similar api with the other client libraries out there are the way to go. This will not be solved now, but I will keep this ticket open and add proper tags to this issue and hopefully revisit in the future. If you have any ides, PR:s are very welcome.
