If using Podman (instead of Docker for Mac) and trivy for image scanning, trivy expects DOCKER_HOST env variable to be setup for scanning local images and fails unless DOCKER_HOST is pointing to the podman socket.

Fix:

Code

$ export DOCKER_HOST="unix://$(podman machine inspect --format '{{.ConnectionInfo.PodmanSocket.Path}}')"
$ trivy image image_name

• ActiveSupport::TimeZone.all which likely fetches a list of available time zones supported by the ActiveSupport library in rails.
• Date::ABBR_DAYNAMES, which is an array containing abbreviated names of the days of the week (e.g., ["Sun", "Mon", "Tue", "Wed", "Thu", "Fri", "Sat"]). This array is provided by Ruby's Date class, making it convenient for developers to access the names of the days without manually typing them out.

While exploring a lengthy code file, we often need to see the available properties and methods without diving into their implementation. In VS Code, this is quite easy with "Fold Level 1" functionality. This feature collapses the code to display only the top-level structures, which makes it easier to understand the file's architecture without getting into the details.

To Use Fold Level 1:

1. Open Command Palette: Ctrl+Shift+P (Windows) or Cmd+Shift+P (macOS).
2. Select Fold Level 1: Now, only the main parts of our code will be visible.

Resolving blocked host:


The Blocked Host is a new feature of Rails 6. To resolve the Blocked Host error in rails, add config.hosts.clear to config/environments/development.rb in your Rails project. This disables the functionality in the development environment, allowing requests from ngrok.

While changing a column type from one type to another and running rails db:migrate , it will throw the below error

Code

PG::DatatypeMismatch: ERROR:  column "tags" cannot be cast automatically to type jsonb
HINT:  You might need to specify "USING tags::jsonb".


above error ^ because i was converting tags field from type string to jsonb
so in order to fix this we have to mention the USING tags::jsonb and cast the type.

Code

class ChangeTagsToJsonbInTils < ActiveRecord::Migration[7.0]
  def change
    change_column :tils, :tags, 'jsonb USING CAST(tags AS jsonb)'
  end
end
