QUESTION
I have a relatively new Rails 6 app (Rails 6.1.3.1), so there's not a whole lot of customization yet. However, I cannot get session variables to persist.
For example, if I put something like the following in a controller action:
...ANSWER
Answered 2021-Jul-15 at 06:00Ok, found the problem. Turns out that I had copied the setting config.session_store :cache_store in development.rb from a different project I had been working on. However, this setting was added as part of the StimulusReflex setup for that other project.
From the StimulusReflex docs:
Cookie-based session storage is not currently supported by StimulusReflex.
Instead, we enable caching in the development environment so that we can assign our user session data to be managed by the cache store.
The default setting for this option is cookie_store. By changing it to :cache_store without specifying a cache repo, it implements ActionDispatch::Session::CacheStore and defaults to storing it in Rails.cache, which uses the :file_store option, which dumps it in tmp/cache.
However, further down in development.rb, there is some conditional logic that assigns config.cache_store to :null_store if there is no caching-dev.txt file. This implements ActiveSupport::Cache::NullStore, which is "a cache store implementation which doesn't actually store anything."
So because I had not enabled caching with rails dev:cache for this project, the session cache was getting toasted with every request.
LESSON LEARNED: Be very careful when copying config settings from an old project to a new one!

I have set enum task_status as:
...ANSWER
Answered 2021-Apr-29 at 16:27If you want to use enum here, then u need to store your enum values as strings in database. Currently your column task_status has integer type. Therefore u can't search with LIKE operator. To resolve it make this change.

I have a project I'm trying to use ruby 3 (previously running with 2.7.2), but couldn't accomplish it.
After updated my gemfile with the ruby version and ran bundle, I'm receiving this error when trying to access rails c:
ANSWER
Answered 2021-Jan-08 at 00:14You have spring in your gemfile, usually hanging consoles and servers are related to that. The webrick gem was removed from the standard library in Ruby 3, so that's why it needs to be included in your Gemfile.
Re-add webrick to your Gemfile, do a bundle install, and then stop the background spring server with bin/spring stop. Then re-run the server.
Your best bet on solving issues with spring would be to head over and read about the gem on the GitHub project page, or opening a new question here on SO.
QUESTION
I'm trying to install the pg_search gem. In the first attempt I did not pay attention to the necessary version of ruby (we are using 2.3.1 and 2.4 was required), in the error message that appeared I was asked to run bundle update, but it updated pg_search to 2.3.5 which require ruby >= 2.5. Even though I specified an older version of the gem, it still shows the same message:
ANSWER
Answered 2020-Dec-21 at 13:28Even though I specified an older version of the gem
No, you didn't.
You specified '~> 2.1', '>= 2.1.4', which means anything 2.1.4 <= version < 3.0.0.
By running bundle update, this installed the latest available version that met your requirements, which was apparently 2.3.5, not 2.1.4.
If you need to also specify a constraint to ruby version 2.3.1, you can also put this in the Gemfile:

I am using rails (5.0.7.2) for a small project. For tags I choose the acts-as-taggable-on and for search pg_search gems. As I want the tags to be searchable, I first created a folder in the app directory called "utilities". Then I crated a file called "search_tags.rb" in that folder.
The content:
...ANSWER
Answered 2020-Jun-17 at 08:56By default everything in app/ is autoloaded, but in config/application.rb you could add:
config.autoload_paths += %W(#{config.root}/utilities/)
to include utilities as well. Or you could do it in config/environments/... to do it on a per environment basis

I'm trying to use pg_search in my Rails application to sort a list of parts based on a query from a user. I've run into some trouble, though -- I can't seem to get correct results from an ascending order search.
Here's my model:

Answered 2020-Apr-02 at 23:58Try using reorder instead of order. reorder will remove any other ordering defined elsewhere in case that's throwing things off.
QUESTION
I'm currently implementing search functionality in my rails app using pg_search for PostgreSQL full text search. Unfortunately, I'm having a problem with getting the migration to add the tsvector column, GIN INDEX and the TRIGGER in the listings table. The migration runs successfully but doesn't create the things specified in the migration file.
Error when trying to access the tsv column:

QUESTION
I'm using the pg_search_scope feature of the Ruby pg_search gem, and I have a Listing model with the following scope:
ANSWER
Answered 2020-Jan-28 at 22:18Cradle => c, cr, cra, rad, adl, dle, le, e
pg_trgm does not ever generate the double-space padded tigram at the end of the word, so the last trigram here is le, not e. This weights the beginning of words more than the ending, which is generally a reasonable thing to do.
Cras => c, cr, cra, ras, as, s
Similarly, there is no s trigram. Also, word_similarity, counter-intuitively, does not force the substring of the right hand argument to align on word boundaries. So it treats 'cras' as if it were 'cra', since that is the higher-scoring substring, so there is no ras or as. And since 'cra' is not aligned to a word boundary on the right hand side, it apparently does not make an ra either.
Maybe you want strict_word_similarity instead.
QUESTION
I am working on a Rails web app. I have records in a model, called AcademicPaper that I deleted using the batch action destroy functionality that comes with activeadmin. Right after I did that, I noticed that there was an error of not found ActiveRecord for the AcademicPaper model in the controller method that utilized pg_search gem.
I realized that the pg_search was not synched with ActiveRecords. Therefore, the solution was for me to run PgSearch::Multisearch.rebuild(AcademicPaper) in the rails console, which I did, which worked.
My question is: how can I avoid this error in a production environment and maybe rebuild the pg_search index every time an active_admin batch action occurs?
ANSWER
Answered 2020-Jan-19 at 03:24Straight from Active Admin Documentation -
If you want, you can override the default batch action to do whatever you want:
