So, this shouldn't change, as this is the serialization

n/m I take that back. You're right. I misread that this was the input being changed, not the output. Rails needs this format as the deserialized attributes.

@dpdawson Awesome! Would you mind adding a changelog entry at the top of the fixes section? Also, a test of an ActiveRecord object using this result would be fantastic, if you don't mind the extra effort. |

As I looked into it more, I realized the error only gets thrown when you validate the relationship is present. The fix doesn't cause any of the other tests to fail, so I assume it's ok. I added a test, but I'm sure it's not the best implementation because I don't use Minitest and the organization of the tests is a bit difficult to discern at first glance. |

Singularizing polymorphic association types allows you to use plural or singular type values in your requests as allowed by JSON API. Because ActiveRecord calls #constantize on the polymorphic association type when you use the hash to create a new model if you validate the presence of the related model, you must capitalize the type to avoid a NameError.

we probably want to encapsulate this singular.capitalize logic in a transformer cc @remear

could we camelize instead of capitalize? that would add support for snake cased multi word model names, right?

assoc_data.fetch('type').underscore.classify
Using [] is dangerous.

With a rebase and a brief look at the Transformer with @remear this should be ready to mege |
|
I'd be happy to take a look if pointed in the right direction. |
|
@dpdawson Could you rebase this off master and take a look at adjusting |
|
Any updates on this? Or has the problem been solved in a different way? I'm currently running into this issue. |
|
One note: I don't think the current implementation will work for multi-word classes, given that the standard wordbreak in jsonapi is a '-' "blog-posts".singularize.capitalize |
|
I get this situation here, by now, I solve with hardcoded fix on controller. I made a SO because I had not seen this. Please consider merge it. |

@brunowego @bartiaco I'm reading the comments above and looks like the PR didn't get finished by anyone. Unless @dpdawson wants to pick it up again, it'll need to be reworked against master, and also related #1928 cc @NullVoxPopuli |
