Hi @jbescoyez !
You have Cannot reach your data displayed ?
The logs you shared are not error logs, do you have any other log ? What about your browser logs ?

jbescoyez · February 8, 2021, 3:18pm

Yes, I do have Cannot reach your data displayed.

I think the issue is at this line:

No template found for ForestLiana::UserSpace::UserController#index, rendering head :no_content

How comes the template is not found and therefore no content is sent?

Nothing special in my browser logs (just an error with Drift):

Nicolas_Sailly · February 8, 2021, 3:26pm

Can you share the UserController class please ?

jbescoyez · February 8, 2021, 3:44pm

Not sure to get you. Do you mean the ForestLiana::UserSpace::UserController or my UserController?

If it is mine, I am not sure it will help. I have the same behavior for all collections.

Nicolas_Sailly · February 8, 2021, 4:07pm

You are right, I won’t see anything there.
Your issue looks a lot like this one.
Are you using fast_jsonapi ?

jbescoyez · February 8, 2021, 4:11pm

Yes, I do. Does it mean that Forest is not compatible with the most famous jsonapi lib in Rails?

Nicolas_Sailly · February 8, 2021, 4:25pm

Actually it should, can you try changing mount ForestLiana::Engine => '/forest' to mount ForestLiana::Engine => '/forest', defaults: { format: 'json' } in your routes.rb ?

Let me know if it works !

jbescoyez · February 8, 2021, 8:01pm

Thank you. It solved the problem but another one arose.

Now, I get the following error:

Records Index error: undefined local variable or method `object' for #<ForestLiana::UserSpace::DocumentSerializer:0x00007ff83db0cfd8>
Did you mean?  object_id

...

I’ve dug a bit and realized that you use GitHub - fotinakis/jsonapi-serializers: Pure Ruby readonly serializers for the JSON:API spec. and I use GitHub - jsonapi-serializer/jsonapi-serializer: A fast JSON:API serializer for Ruby (fork of Netflix/fast_jsonapi) (the new name of fast_jsonapi). The two libraries define the following constant JSONAPI::Serializer with a different API.

I do not really know what to do. What do you recommend?

Hey @jbescoyez,

Thanks for taking the time to look into it. I created an issue, you can follow its progress here:

jbescoyez · May 6, 2021, 3:26pm

Hey @vince Is it still under your radar? Tnx

arnaud · May 7, 2021, 9:15am

Hi @jbescoyez, sorry we delayed this topic, waiting for a dedicated Rails developer to join the team.
As we didn’t find the right teammate (yet), I think we’ll have to prioritise the investigations about this issue and have a look at it next week.

arnaud · May 14, 2021, 7:09am

Hi @jbescoyez, the team is still looking for the appropriate solution here.
There is no easy win, but we are getting closer to decide how to prevent this conflict.

jbescoyez · May 14, 2021, 8:59am

Indeed, I already thought what I could do and it is surely not easy.

Thanks for investigating. I am sure it will benefit other users since https://github.com/jsonapi-serializer/jsonapi-serializer is now the go to serializer for any JSONAPI Ruby backend.

jbescoyez · May 31, 2021, 8:51am

Hi @arnaud! Any update? Tnx

jeffladiray · May 31, 2021, 9:44am

Hey @jbescoyez,

We are currently working on it. I opened a PR available here that still need some work in order to be fully operational. It might also introduce a breaking change, meaning it’ll be available in the beta release, hopefully this week.

You can definitely try it out though, using the github path or by cloning the forest rails repo and installing the gem via

gem 'forest_liana', path: 'path/to/your/forest/rails/clone/forest-rails'

This is far from a perfect solution, but be sure that we are still working on it.

Let me know if you try it, any feedback will be appreciated

jbescoyez · May 31, 2021, 9:37am

I have just tested it and everything is running smoothly. Tnx!

jeffladiray · June 1, 2021, 9:34am

Good to know it works.

I’ll update the thread once a proper release is done then. Thanks for your feedback

This is released in 7.0.0.beta.1.
Keep in mind that this is a beta, so it might include other breaking changes by the time it is released
