It's important to stay connected with what's going on in the world (even if that means spending hours scouring reddit rather than accomplishing anything productive). Let's build a news aggregator so we can share some pointless articles and help others waste time effectively.

Learning Objectives

  • Build an application that receives user input via HTTP POST requests.
  • Persist user data on the server so it can be used to generate pages dynamically.

Instructions

Build a web application using Sinatra that displays a list of articles that users have submitted. The application should satisfy the following user stories:

As a slacker
I want to be able to submit an incredibly interesting article
So that other slackers may benefit

Acceptance Criteria:

  • When I visit /articles/new it has a form to submit a new article.
  • The form accepts an article title, URL, and description.
  • When I successfully post an article, it should be saved to a CSV file.
As a slacker
I want to be able to visit a page that shows me all the submitted articles
So that I can slack off

Acceptance Criteria:

  • When I visit /articles I should be able to see all the articles that have been submitted.
  • Each article should show the description, title, and URL.
  • If I click on the URL it should take me to the relevant page inside of a new tab.

For an extra optional challenge, implement the following additional user stores:

As an errant slacker
I want to receive an error message
When I submit an invalid article

Acceptance Criteria:

  • If I do not specify a title, URL, and description, I receive an error message, and the submission form is re-rendered with the details I have previously submitted.
  • If I specify an invalid URL, I receive an error message, and the submission form is re-rendered with the details I have previously submitted.
  • If I specify a description that doesn't have 20 or more characters, I receive an error message, and the submission form is re-rendered with the details I have previously submitted.
  • The submitted article is not saved in any of the above cases.
As a plagarizing slacker
I want to receive an error message
When I submit an article that has already been submitted

Acceptance Criteria:

  • If I specify a URL that has already been submitted, I receive an error message, and the submission form is re-rendered with the details I have previously submitted.
  • The submitted article is not saved in the above case.
