Hey @Kronos66 I tried this PR and I can actually see the versions dropdown now, but no data are saved in the db table versions when applying changes to the content, so the dropdown remains empty (I see just the entry current).

On a single types (named global in the img below) I got this error, I'm on postgresql:

Hi @vuolter, I added support for single types.
Could you check this again?

Hey @Kronos66, I tested your latest changes and by applying just a few small changes I was able to get the plugin finally working fine on my side. Thanks for your amazing support! ❤️

We need to check if the query returns actually an entry, I changed this block to:

const entry = await model.findOne({});
if (entry) {
  knexQueryBuilder.where({
    content_type: contentType,
    entity_id: entry.id,
  });
}

good catch I will fix this in next commit :) thank you

Looks like el.entity is already an object, I reverted to:

content: el.entity,

[Kronos66]

Strange, because we write data to database as json and here we always get string

Hey @Kronos66 I tried 0d5e94c and I can confirm it fails with JSON.parse(el.entity):

[Kronos66]

I have one question about this problem, what database do you use?

[vuolter]

postgresql

[vuolter]

If i remember correctly this happens also with built-in sqlite @Kronos66

Hi, @vuolter , sorry for delay
I added the saveParse method to handle objects, now everything should works correctly

[vuolter]

Hi @Kronos66, sorry to reply so late.... I tried your latest changes under sqlite and mysql on a fresh installation and everything looks working fine, on both.
I'll try to check on postgresql as well and let you know.

I am getting TypeError: Cannot read property 'listEntityVersions' of undefined when I try to spin it up, but if I remove the first route in the routes.json file, I can spin up my environment, however, it is unable to get the versions of the collection types. Has anyone else gotten this or know how to fix it?

{
      "method": "GET",
      "path": "/explorer/versions/:model/:id",
      "handler": "Versions.listEntityVersions",
      "config": {
        "policies": []
      }
    },

What's the status on this @Kronos66 ? I need versioning in an app, if this works it'd be great :)
