Multiple MySQL Versions for Development

Options included below:

• Using Docker docker-compose
• Using Homebrew brew

Using Docker (recommended)

This gist was originally created for Homebrew before the rise of Docker, yet it may be best to avoid installing mysql via brew any longer. Instead consider adding a barebones docker-compose.yml for each project and run docker-compose up to start each project's mysql service.

Some CoffeeScript (verbosely commented for clarity)

# Override Rails handling of confirmation

$.rails.allowAction = (element) ->
  # The message is something like "Are you sure?"
  message = element.data('confirm')

When hiring Ruby on Rails programmers, knowing the right questions to ask during an interview was a real challenge for me at first. In 30 minutes or less, it's difficult to get a solid read on a candidate's skill set without looking at code they've previously written. And in the corporate/enterprise world, I often don't have access to their previous work.

To ensure we hired competent ruby developers at my last job, I created a list of 15 ruby questions -- a ruby measuring stick if you will -- to select the cream of the crop that walked through our doors.

What to expect

Candidates will typically give you a range of responses based on their experience and personality. So it's up to you to decide the correctness of their answer.

Friendly URLs

By default, Rails applications build URLs based on the primary key -- the id column from the database. Imagine we have a Person model and associated controller. We have a person record for Bob Martin that has id number 6. The URL for his show page would be:

/people/6

But, for aesthetic or SEO purposes, we want Bob's name in the URL. The last segment, the 6 here, is called the "slug". Let's look at a few ways to implement better slugs.

querendo progredir às custas dos outros. Não pense q pq vc sentou 4
anos numa faculdade ouvindo um professor falar sobre software q vc
