Algolia:initialize not working (rails aborted - don't know how to build task)


first of all, this is a copy of my post into official algolia-discourse. As told by Discourse-Support, I can now post it here, therefore this is a copy-message.

I would like to setup our discourse with algolia, but it is not working like described on GitHub. I have newest version: 3.1.0.beta1.

To make first init, I open my discourse-docker with

./launcher enter app

After that, I tried different commands (bundle exec rails or only rails, also rake), but all results into:

root@rbx-communtity-service-app:/var/www/discourse# LOAD_PLUGINS=1 rails algolia:initialize
rails aborted!
Don’t know how to build task ‘algolia:initialize’ (See the list of available tasks with rails --tasks)
Did you mean? algolia:reindex

When I run just algolia:reindex, i get the following:

root@rbx-communtity-service-app:/var/www/discourse# LOAD_PLUGINS=1 rake algolia:reindex

Any idea whats the issue here?

Thanks in advance!

I have installed this on my test site to give it a run-through and I also see a similar thing. Let me see what I can find out. :+1:


Have you set the algolia_discourse_username site setting by any chances?


It is set to “system”

algolia:initialize does not exist any more. See FEATURE: Update to latest algolia gem (#33) · discourse/discourse-algolia@9a1f08f · GitHub

The needs an update.


README updated :+1:


The issue regarding reindex is still existent. I made a complete upgrade of discourse, including algolia. Also, I could not yet found a code-change inside algolia-plugin. Are there any plans on working on this?

Right now, only readme is changed, but function is still not working like initially written by me.

If needed, I can send you fresh logs from console.


There was a bug fix earlier today for an issue with reindexing and topic counts:

On the off-chance, could this have solved your issue too?

Unfortunately no :frowning: This fix is already inside my discourse-version. Same issue as before.

I was over optimistically hoping for some ‘magically fixed’ :slightly_frowning_face:

I’ve given it another go on my test site and I also hit the same issue again. However, I have managed to find out some more information. :partying_face: Apparently we’re both experiencing an issue where we have at least one orphaned post that lacks a topic id, which is throwing off the rake task. The advice is to track those down and delete them, and then the rake reindex can run smoothly.

I haven’t put this into practice for finding the problem post(s) yet so haven’t got a step-by-step, but thought I’d give you a heads up in case this is something you’d like to explore before I get to it. :+1:


I am debugging it right now.

Did you change default algolia_discourse_username site setting? If yes, please ensure that you are using non-admin user.


I have given this yet another go… :slight_smile: And I can confirm that removing ‘system’ from the algolia discourse username setting and running rake algolia:reindex with a dummy user instead worked without error. :+1:

I shamefully did not spot the bit in the instructions about:

It is recommended that you create a dummy separate user who can only see content you consider to be public, and change this value to their username.

And only matched my settings per this instruction:

Once all of the settings are turned on and populated, the plugin configuration should look like this:

Personally, (and I may be biased :slight_smile:) I think we could maybe make those instructions a little clearer. :slight_smile: I would advocate for a section ‘Create your algolia discourse user’ as part of the configuration flow.


Actually, in latest PR I removed that option as it is possibly dangerous. When a user with admin access is used, it can show restricted posts in search.


That’s an even better idea. :slight_smile:


thanks, now it is working :slight_smile: My three indices are created and sent to algolia!
