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. #vs-code, #coding

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

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.
```class ChangeTagsToJsonbInTils &lt; ActiveRecord::Migration[7.0]
  def change
    change_column :tils, :tags, 'jsonb USING CAST(tags AS jsonb)'
  end
end```

In a typical Rack middleware setup, the call method handles the initial request and generates a response, but it does not control subsequent redirects initiated by external services. If an external service, such as Slack's OAuth, triggers additional redirects after your application responds, modifying headers for those redirects within the same call method may not be directly achievable. Handling subsequent redirects may require alternative approaches, such as additional middleware or different parts of your application's code. <#CU6U0R822|rails> , #rack , #middleware
