This exercise is intended to help you assess your progress with the concepts and techniques we've covered during the week.
For these questions, write a short snippet of code that meets
the requirement. Fill in your answers on a second sheet of paper or in your
notebook. In cases where the question mentions a "given"
data value, use the variable given
to refer to it (instead of re-writing
the information).
Fork this gist. Answer the questions to your best ability and with limited research. No need to post your gist in the comments.
What is the purpose of the router in a Rails project?
It is like a doorman of the application that knows where to go and what action to take once HTTP request has been received.
What routes would be provided to you with the line resources :items
?
:items routes, I assume, which is probably some controller class
Because I couldn't find these with a quick Google search on 28 April 2015: | |
Usage: | |
rails new APP_PATH [options] | |

[--skip-gemfile], [--no-skip-gemfile] # Don't create a Gemfile |
To use Bcrypt: | |
uncomment "gem 'bcrypt', '~> 3.1.7'" in Gemfile | |
User model should have password_digest attribute | |
add "has_secure_password" to User | |

To display flash messages: | |
add the following to views/layouts/application.html.erb right before yield line: | |

Rails comes equipped with three environments: test, development, and production. The default environment for the Rails console is development: | |
$ rails console | |
Loading development environment | |

=> "development" | |
>> Rails.env.development? | |
=> true | |
>> Rails.env.test? | |
=> false |
AltFuelFinder | |
Alisher Sadikov | |
Pitch | |
People would use alternative fuel consuming vehicles more it was easier to navigate accross the country. Finding fuel stations along the route is one of the diffuclties they face. | |
Problem | |
It is really hard to plan your driving trip across the country if your vehicle uses alternative fuels. You have to spend a lot of time trying to figure out the fuel stops. |
I had to change div1 display to inline-block, put the other two divs into a container and floated the whole container to the right.
Set div2 margin to auto in order to center and gave absolute position to div3 with a right margin of 0.
