no connection pool with primary found

Asked 2019-Mar-22 at 15:41

I am using Rails and am experiencing a connection pool error very randomly and it does not target any single endpoint specifically. I can hit endpoints about 70% of the time without getting this error. The database is PostgreSQL running on Google Cloud. Here's the main stuff of the error I'm getting:

gem 'sqlite3', '~> 1.3.6' bundle install

rake db:migrate and restart server

Should works :)

QUESTION

Pushing to Heroku fails due to unsupported Ruby version even after Gemfile was changed

Asked 2019-Mar-22 at 11:35

I'm trying to push a forked repo to Heroku but Heroku won't accept the push because Ruby 2.3.1 wasn't accepted. I changed the version to 2.3.3 in the Gemfile and running bundle install --without production, but oddly enough it was still considered to be 2.3.1. The same things happened even after trying other Ruby versions, such as 2.4.0.

QUESTION

All tests throwing TypeError: no implicit conversion of nil into String

Asked 2018-Feb-12 at 20:13

UPDATE 20180209: I created a new dummy app with what comes with the initial Rails 5.1.4 install (which includes minitest 5.11.3) and tests completed without issue. Going to continue to experiment with the gemfile to see if I can't narrow down what in the world may be causing this problem...

If you have any ideas or pointers, please let me know!

I recently started testing a new portion of my codebase and I've discovered a very critical issue. For whatever reason, every test is now throwing the titled error. Looking into the trace, it looks like for some reason the quoted name/title of my tests is causing a problem. Going back and running tests that I know were passing (though admittedly on earlier gem versions) unfortunately yields the same results, as shown below with the User model.

I've tried everything I know to do, including completely removing and reinstalling RVM, Rails, and Ruby. I've even tried versioning Minitest to an earlier build, like 10.5.3, but still no luck. I've spent most of the day trying to fix this; I'm at my wits end and desperately need help! Though I've learned the hard way that I now need to explicitly version protect ALL of my gems ;)

Thank you in advance! Please let me know if you need me to include any more files/snippets. I'll do my best to reply to any questions as my schedule allows, hopefully within 24 hours.

Got this sorted out by reverting to an earlier commit when things were working as expected, and pulled in needed updates through a $ git checkout approach.

If I had to guess I think the problem I was having may have had something to do with my intervening update to 2.5.0 through RVM, which introduced more headaches than it was worth (not Rails's fault, or even RVM's since 2.5.0 isn't yet officially supported by RVM).

can't run rspec in RoR

Asked 2017-Jan-19 at 06:54

I'm beginner in RoR, I have an error When I run rspec in rails I'm getting this error message:

You have already activated json 2.0.2, but your Gemfile requires json 1.8.6. Prepending bundle exec to your command may solve this. (Gem::LoadError)

I have tried to update json gem by "bundle update json", but still getting the same error message.

Could someone helps me on this. I'm using:- Ruby 2.3.0 - Rails 4.2.7.1 - gem version 2.5.1 Thank you!
