- You MUST NOT try and generate a Rails app from scratch on your own by generating each file. For a NEW app you MUST use
rails new
first to generate all of the boilerplate files necessary. - Create an app in the current directory with
rails new .
- Use Tailwind CSS for styling. Use
--css tailwind
as an option on therails new
call to do this automatically. - Use Ruby 3.2+ and Rails 8.0+ practices.
- Use the default Minitest approach for testing, do not use RSpec.
- Default to using SQLite in development.
rails new
will do this automatically but take care if you write any custom SQL that it is SQLite compatible. - An app can be built with a devcontainer such as
rails new myapp --devcontainer
but only do this if requested directly. - Rails apps have a lot of directories to consider, such as app, config, db, etc.
- Adhere to MVC conventions: singular model names (e.g., Product) map to plural tables (products); controllers are plural.
- Guard against incapable browsers accessing controllers with `allo

# Basic key operators to query the JSON objects : | |

...and obviously we're building a workaround. But I'm absolutely flabbergasted that a standard <input type="date">
HTML field, in a standard browser, from a company that bases its reputation good design, could be so dreadful.
I'm the developer for a startup that sells a genetic test to recommend medications for high blood pressure. For medical reasons we need to know our customers' birth date. Most of our customers are in their 60s or older. We've found that many of them use iPads or iPhones. And they're the ones who complain to our customer support that our site is unusable.

By default, simply adding the call 'searchkick' to a model will do an unclever indexing of all fields (but not has_many or belongs_to attributes).
In practice, you'll need to customize what gets indexed. This is done by defining a method on your model called search_data
def search_data
extension_id=jifpbeccnghkjeaalbbjmodiffmgedin # change this ID
curl -L -o "$extension_id.zip" "https://clients2.google.com/service/update2/crx?response=redirect&os=mac&arch=x86-64&nacl_arch=x86-64&prod=chromecrx&prodchannel=stable&prodversion=44.0.2403.130&x=id%3D$extension_id%26uc"
unzip -d "$extension_id-source" "$extension_id.zip"
