Markdown presenter method returning static value of markdown field

(Netzc) #1

Hello aaron,

I still have the code reloading bug happening, although the changes from 0.9.0beta3 are in place. Changes to a node’s field content are only visible in the front end when I restart the server. I tried a lot of cache related stuff, only a server restart seems to do the trick

I’m not sure what I can give you to help. What I found is, that it works when I use @node. in the node’s view, I see the changes to the field’s value I made in the backend, while if I use @., I see a stale version of the field’s value.

I’ll gladly supply logs, etc, if you let me know what you need.


Edit: I’m running 0.9.1 on rails 5, ruby 2.3.0 on xenial.

Version 0.9.1 released

Sounds a bit different to Rails 5.0 Code reloading fails

Can I clarify what’s happening:

  1. Update the content of a node through the admin UI
  2. Reload the node url on the front end
  3. The @node variable returns the correct content
  4. The @whatever_node_name (the presenter class) variable returns the old content before you made any changes

Have I got that right?

Spot on. Can I add that I’m very impressed with the speed of your replies!

:smile: although unfortunately I won’t be able to look in to this quite so hastily. I should be able to take a look tomorrow afternoon/evening though.

In the mean time there may be a workaround. Try explicitly generating the presenter class for the node type you’re working with. Eg:

rails g push_type:presenter whatever_node_name

Then restart the server. Let us know if that makes a difference or not as it narrows the problem down somewhat.

Multi lang support?

Yes, after a restart changes to fields’ values are reflected on the frontend.

I understand there is some serious ruby metaprogramming going on here? I really need to brush up on this :slight_smile:

Thank you for your help, once more.

Yeah, the presenter classes are dynamically defined, unless you explicitly create one to add your own presenter logic… To be honest, it may be a bit too “magic” for some people’s tastes, so it may change in future.

I’ve moved this issue into it’s own thread and will take a look tomorrow.

@netzc I’ve just released a new gem that fixes this issue. Try version 0.9.2.

This bug was introduced a few months ago - the method defined on the presenter class was returning a static value - the markdown wasn’t being recompiled every time. This is the fix:

Thanks for spotting this and reporting this one :slight_smile:

I’ve made a few other minor improvements to the markdown field (most notably, now using codemirror to style/highlight content in the editor). There’s more to come with markdown - in future I want to the markdown field to integrate nicely with the media library, but that may be some months off right now.

What can I say:
fixed! :clap:

Also, I love the changes to the markdown fields. in 0.9.1 I shied away from markdown fields because occasionally the markdown indentation was botched up in the admin’s form field.
This was discouraging because I had just about brought my main content author (my sister) up to speed on markdown.
Boy does she love to nest lists, which is no fun in wysiwyg.

So, @aaron, your fix is a fixer-twofer for me.
