Hello,

I tried to install the [topic voting plugin](https://github.com/discourse/discourse-topic-voting), but got the following exception upon loading a page:

```plaintext
ActiveRecord::StatementInvalid in ListController#latest
PG::UndefinedTable: ERROR: relation "topic_voting_votes" does not exist LINE 10: WHERE a.attrelid = '"topic_voting_votes"'::regclass ^

```

Is there some process that must be done to create the tables? (All I did was clone the plugin into a subfolder of the plugins directory, no other setup steps were taken other than a restart)

**Update - Resolved** : I wasn’t aware of this, but when installing plugins on a development site, you need to manually run:

```plaintext
bin/rails db:migrate

```
