Trying to get property of non-object

[damngoode]

After creating a software license and checking it out I am no longer able to view assets/software checked out be that user. Checking in the software does not correct the problem. Below is the error log that it returned:

Hi there - sorry for the delay, I was out at a conference. Which branch did you grab, dev or master?

When you see "Trying to get property of non-object", does it give you a line number or file number in the error?

[KurzweilTV]

Maybe I can add to this. I'm getting the same error. I get an error anytime I click a user that has assets assigned.

here is my log-apache2handler if that helps

[snipe]

Can you tell me what error you see on screen?

[KurzweilTV]

server error 500

[snipe]

Are you running this as production or local? If you run it as local, you'll see a more useful error message on screen.

[KurzweilTV]

I think production. I'm not the one that did the original setup. If it can be changed to local I'll see about doing that. This is from the 0.32 release

[snipe]

Okay - if you can run it as test or local, that would definitely help me to help you. It should show you a line number with the offending bit, and I can help you debug from there.

[snipe]

(When it's in production mode, it gives more user-facing, generic error messages - dev/test mode gives a full stack trace and more detailed debugging.)

[KurzweilTV]

I hate to ask, but is there an easy way to switch between the two?

[snipe]

No worries :) Easiest way is to adjust the environment settings here:
https://github.com/snipe/snipe-it#2-setup-environment-database-and-mail-settings

[KurzweilTV]

Hmm followed that but I still get generic errors. I'll have to try later. Busy day. :(

[snipe]

It will default to production if the hostname doesn't match, so that may be part of the problem. When you type hostname, does it match what you have as local, and NOT what you have as anything else in that block?

[KurzweilTV]

Yeah it matches exactly, and only the section that says local.

[snipe]

Hmm, okay. A few more questions for both of you if you get a chance:

• does this happen with any user, or just a selection of them?
• does this happen with software and hardware, or just software?
• does this happen with any assets, or just assets you create and assign?

If you remove the following:

@if ((isset($log->assetlog->name)) && ($log->assetlog->deleted_at==''))
    <a href="{{ route('view/hardware', $log->asset_id) }}">{{ $log->assetlog->asset_tag }}</a>
@elseif ((isset($log->assetlog->name)) && ($log->assetlog->deleted_at!=''))
    <del>{{ $log->assetlog->name }}</del> (deleted)
@else
missing asset ({{ $log->assetlog->name }}) ({{ $log->assetlog->deleted_at }})
@endif

from app/views/users/backend/view.blade.php and reload, does it help?

I'm having a hard time reproducing it on my end, so I'm trying to isolate the use cases. :(

[KurzweilTV]

Sorry for the lack of info. I find out what I can.

No problem - sorry you're having trouble. PS - I edited your comments to remove your phone number, for probably obvious reasons. I think it was included because you replied via email, and it's in your sig.

[KurzweilTV]

Thanks for the edit!

Also, it was only happening to users with software assets assigned, users with hardware were okay.
Removing that block made it work perfectly. Thank you, and I hope that helps!

[snipe]

That does help, thank you! I'll get a patch out for you shortly. I appreciate you taking the time to help troubleshoot. Sucks when you can't reproduce an error locally.

[KurzweilTV]

Thank YOU! This project is exactly what I needed.

[snipe]

Can you try adding this bit of code after line 139 on app/views/users/backend/view.blade.php? (It's basically the same line you took out before with the last else changed to an elseif.

@if ((isset($log->assetlog->name)) && ($log->assetlog->deleted_at==''))
    <a href="{{ route('view/hardware', $log->asset_id) }}">{{ $log->assetlog->asset_tag }}</a>
@elseif ((isset($log->assetlog->name)) && ($log->assetlog->deleted_at!=''))
    <del>{{ $log->assetlog->name }}</del> (deleted)
@elseif (!isset($log->assetlog->name))
missing asset ({{ $log->assetlog->name }}) ({{ $log->assetlog->deleted_at }})
@endif

If this works, that's really weird. That statement should only evaluate to true if the asset itself or the entry in the log table is missing, which should never happen, since assets are marked as deleted, but never truly deleted.

Edit: Updated to correct the code. Use this version, not the one you were emailed with the github response.

[KurzweilTV]

Tried the new code.

I get the original error when I use it.

[snipe]

Dammit. :( Thanks. Stay tuned.

[snipe]

Try this?

@if ((isset($log->assetlog->name)) && ($log->assetlog->deleted_at==''))
    <a href="{{ route('view/hardware', $log->asset_id) }}">{{ $log->assetlog->asset_tag }}</a>
@elseif ((isset($log->assetlog->name)) && ($log->assetlog->deleted_at!=''))
    <del>{{ $log->assetlog->name }}</del> (deleted)
@endif

So sorry for all this back and forth. I still can't repro, so I'm still flying blind. :(

[KurzweilTV]

No prob. Happy to help

This one works perfectly.

[snipe]

Excellent! I'll submit this patch into dev and master, so the next time you grab code, the fix will be in there. Really appreciate all of your help!
