I got this error in running heroku run rake sunspot:solr:run
rake aborted!
You need a Java Runtime Environment to run the Solr server
is there a way i can install jre in heroku?
You cannot install the JRE on Heroku, and thus you cannot run Solr from a Heroku worker.
If you want Solr in Heroku, you'll have to use the Websolr addon, or start an EC2 server and run your own copy of Solr from there.

Right now I have a docker container running a rails 6 app in Heroku. Now I am wondering if there is a way to run some rake task. I have tried:
heroku run bash
heroku run rake -T
heroku run rails console
But all of these commands execute rails server for some reason. Is it possible to run rake tasks if I am using Docker?
I have deployed a rails application using capistrano on a linux server and it is running without any problems. When I connect to my remote server via ssh, the folder structure of my app is quite different from what I have on my local machine. I would like to go to project root and say rails console so that I can have access to the console of my application. Is there a way to achieve this?
When I go to ~MyApp/ folder and run rails console it says command rails not found. I think that is probably because the app is running in another folder.
bundle exec to the rescue inside of project folded:
$ RAILS_ENV=production bundle exec rails console
If you've installed with rbenv it could be that you are defaulting to the wrong Ruby version. So you can run rbenv exec to get it to run on the right version, along with bundle exec to run the right version of Rails
So try running this:
rbenv exec bundle exec rails console
To sum up for anyone having the same problem in the future,
I went to MyApp/releases/2020331231231231 which is the latest release of my app and there I used this command RAILS_ENV=production bundle exec rails console and I was able to do whatever I wanted to do in the console.
First you need to move inside the folder where the code is.
Check Capistrano config if deploy_to is defined. (If it's not it should be set to /var/www/#{application}/ by default read here)
Since Capistrano keep older versions of your app go to the current folder which is a symlink of the latest deployed version.
And run ENVIRONMENT=production bundle exec rails c or ENVIRONMENT=production bin/rails c. If doesn't work try with rbenv ENVIRONMENT=production rbenv exec bundle exec rails c
I'd like to copy the Postgres database from a production environment to a test environment, but it doesn't seem that the Heroku CLI is available on the Heroku app server (heroku run bash, then try running heroku).
Ideally I could do this using Heroku Scheduler, but for now I'm running this command locally:
heroku pg:copy [myapp]-prod::postgresql-[stack]-[id] postgresql-[stack]-[id] --app [myapp]-test
Any thoughts or suggestions?
so i've successfully installed Harrys Prelauncher on Heroku (https://github.com/harrystech/prelaunchr)
and to export my collected emails into a csv i need to run this command (bundle exec rake prelaunchr:create_winner_csvs)
is there any way to run that command through pgadmin or some other program?
or is the only way for me to download my heroku database and run the command locally? also how and what would i need to do this?
i'm pretty new to rails and postgresql and would really appreciate if someone could help me out!
Because the rake task creates files locally you can't just run it on heroku via heroku run rake. You can however set up your local database.yml to connect to your heroku postgresql instance and run the rake task locally.
Run heroku pg:credentials to get the required database values.
Fill in the production environment of config/database.yml with the values you obtained from step 1 (for the value of 'database' in the yml file, use dbnmae from step 1)
Test your connection with RAILS_ENV=production rails db. This should drop you into a psql console.
Run the rake task. RAILS_ENV=production bundle exec rake prelaunchr:create_winner_csvs
The files will save locally in lib/assets as indicated by the documentation.
From within the directory of the project you can use
heroku run rake prelaunchr:create_winner_csvs
You should probably create a UI form in to your application.
On click on export CSV, it should run background job on heroku (Using delayed jobs).
heroku run rake prelaunchr:create_winner_csvs
Use send_data ruby method. To send your generated and dumped data file on to your browser.
Download the file on to your local system from running heroku instance.
Hope this will resolve your problem.
Cheers!!!
I ran into this problem recently while developing the Prelaunchr campaign for a client. Assuming you have a local version of your app and are using Postgres Copper in Heroku, you can "pull" your Heroku database down to your local machine, set that as your development database in database.yml, and run the rake task from your local app, which should now have the same database as your heroku version. Here is the command to pull the db (subbing out name_for_database & heroku_app_name with your own):
heroku pg:pull HEROKU_POSTGRESQL_COPPER_URL name_for_database --app heroku_app_name
Make sure to restart your local server to see the new database info populated.
I have successfully installed and configured apache with passenger for deploying a rails application. I installed the 'mysql' and 'rails' gems successfully, but when I run any rake commands like
rake db:create
to create the database, I get this error
Illegal instruction
Any idea why?
