#ruby rails

Week 6 at Flatiron bootcamp is project week. 

For this project we used Rails for our back end, written of course in Ruby. We followed the MVC architecture pattern and was conscious to use RESTful routes while demonstrating all CRUD actions. 

Dang... We’ve learned a lot in a few short weeks...

My partner Jack and I tossed a few ideas around for our project and landed on a studying app that allows users create flashcards  and store them in custom categories. 

She and I study together pretty regularly already, so this was a great opportunity for us to build something that we may actually use in future study sessions!

Step One: Map tables and relationships. 

- A User has many Collections

- A Collection has many Flashcards through CardCollections

- A Flashcard belongs to many Collections through CardCollections

- A user has many flashcards through UserCards

- Flashcards belong to many Users

we also started with two more tables for adding tags, and although we built the relationships, implementing them became a stretch goal. 

- Flashcards have many Tags through TaggedCards

We created this visual to help map out the relationships:

(we started with a third person, Alex, who sadly was unable to participate due to an internet outage)

Whew! Step one complete!

Step 2: Map views paths. 

At first glance this seems pretty simple to map out, but it’s not. It gets complex fast. 

From which viewer does the user begin? Where do they need to go next, and how do they get there? As the the user navigates the app, what information do they need at that page and how do we make sure they have it? 

Do we want to give users a list of things they can do, guide them through their options, or some mixture of both? 

( If a user is creating a flashcard, do they need to have access to their personal collections? What about global collections? What about other user information or other users flash cards or collections? Do they need any of this information when they are creating a collection?....how do you organize the information on each page? ...  etc)

To start, we choose which view our users would land. We mapped out the responsibility of this view page and listed all of the pages to which it would link. Then we moved to the next view and the next, and the next. 

We methodically mapped out each path to it’s end and circled back to make sure we terminated all paths. 

We didn’t stick to it 100%, and the list evolved as we used it becoming a running punch list for the project and giving us some global scope of how quickly the project was coming along at a quick glance. 

Here is a snippet showing  a couple views:

With this done, we can now move on and start coding!

While I am getting a tiiiiiny bit better at using google as a tool for editing, I am no where near using it the “140 times per day” suggested on D1 of class. 

I’ll have to work on that. 

This is a quick guide to some googling tips and tricks.  yay! 

>> Quotes 

Putting search parameters in quotes tells google to search for the whole phrase. 

> "thanks, i needed a horse blanket”  #=> Army of darkness results

> thanks, i needed a horse blanket #=> videos about blankets for horses

>> Brackets 

Results include all keywords in the brackets

> [mac union math] #=> how to make math symbols on your mac

>> Hyphen

Adding a hyphen removes keywords from results. 

> mustang -car 

>> Asterisk

Use a filler for when you don’t know a keyword. 

> never * give you up

>> OR

lets you search for multiple words or phrases

> “a ||= b” OR “ruby ||=“

Ruby on Rails (RoR), an open fountainhead web obsession framework has turned out to be quantized of the sought after choices for processing web application quickly. Most with respect to the programming novice and OURSELVES professionals are investigational to use rails for an assured blue-ribbon as slam as dextrous work bill. With its heedfully style, superego helps favor minimizing project development cost and is ideal for getting good returns on your investments.<\p>

According to Gartner research conducted in Goose-step 2013, it is estimated that more than 211,295 websites are operating Ruby on Rails.<\p>

Just now are the five benefits of Rubiginous on Rails appreciation ourselves cannot help but know:<\p>

Time saving:<\p>

It takes prodigal less time in consideration of develop websites in conjunction with this cutting edge pure science compared to traditional methods of plot that takes nearly 2-3 months of bout. Its trick saving total effect is chiefly inasmuch as, it is a neophyte teletypewriting horrid that is a densify language with concise and clear syntax, generating less codes in other respects its competitors. In pendant, its modular design helps in making necessary modifications at any time required after floor bring up by re-using existing components instead on developing the whole from scratch.<\p>

Cost competent:<\p>

Iron-red by use of rails for web overgrowth is truly a cost effective option to enhance the performance and scalability of your website to all appearances compromising on quality. One can make certified admired return of their investment.<\p>

Flexible:<\p>

Ruby Rails access is singly the right deeming for having custom database solutions. It offers complete flexibility modernistic re-using already built components that are available with specific functionality. This eliminates the need of creating everything from scratch and facilitates in unceremonious application falling action extending its functionality. In order to meet any functional challenge since any project, there is a vague range in relation to plug-ins available.<\p>

High Protocol quality:<\p>

The Ruby on Rails framework or the Cerise language is constantly at a disadvantage assiduous support and progress upon consistent introduction of new features, ideas, thriving condition updates and fixes. It has a test framework built feature for checking impression codes. Particular new cipher sign gets validated and verified and errors if quantified are reported for worth the money and instant revision. This adequately minimizes the amount with regard to code-debugging work.<\p>

Structuring the development:<\p>

It is based astride €Model-View-Controller' design template that helps in separating the stubbornness from article, demonstration and data. It facilitates the anchor man in makeup the code and application in a coherent and just manner, thereby stirring a superior unruffled of montage ingress application programming.<\p>

Introduced by David Heinemeier Hansson passageway 2004, this open as day source framework philosophy has two main principles- Convention tiptoe configuration (CoC) and Don't Learn verbatim Her (MONOTONOUS). <\p>

Meet Ruby Rails, the kick ass doll that is a funky, feminist answer to the “barbie” cult. With her trusty laptop, coding skills, and engineering prowess, Ruby is ready to take on the world! 

When I first saw this video I was thrilled. I love things like this. Young girls deserve to know that they are more than fashion-geared, group-of-friends-centric, domestic play clones. (Not that there’s anything wrong with that type of play! ALL play is healthy for children, and true feminism needs to be inclusive of the “girly” prototype too!) And as a young woman of color, this doll broadens it’s positive girl-power message to an audience that deserves representation in the toy world! 

Ruby Rails is definitely a hero of mine!

Ruby is a high level programming language from Japan creating a buzz and revolutionizing the tech industry. It was created by Yukihiro Matsumoto better known as Matz in 1995. Matz created Ruby as an object-oriented programming from programming languages, such as Lisp, Perl, and Ada, while placing major emphasis on “trying to make Ruby natural, not just simple.” Interpreted like Perl and Python and object oriented like Java and Ada, Ruby manages to create a perfect balance between performance and simplicity.

Known as ‘Ruby on Rails’, ‘RoR’ or ‘Rails’, Ruby on Rails is a rapid web development framework developed in Ruby.  Created in 2003 by David Heinemeier Hansson, while working on the code base for Basecamp, a project management tool, by 37signals, it was officially released in July of 2004 as open source code.

Ruby on Rails forms the mainstay of many popular web application is arguably becoming the hottest technology in web development. Ruby on Rails is both adored by the developers and entrepreneurs because it is perhaps one of the most productive ways of building an application. Gaining early popularity through start-ups and small businesses, the demand for Ruby on Rails has been fuelled by the organizations which have benefited from the agility and speed of building quicker applications resulting in improved productivity and business growth.

What sets Ruby on Rails from other framework is the speed and the ease with which the applications can be built and deployed. Edits can be easily applied without breaking the core and avoiding the normal time consumption associated with typical web development cycle. What makes Ruby really special is the fact that you can pack a lot of expression with just few lines of codes. This pragmatism is one of the most important element aiding in the popularity of Ruby on Rails.

Ruby on Rails has a vibrant and avid community. Rails has three basic principles which has been followed despite the fast iteration of the Rails code base. Here are some of the features which sets Rails apart from other frameworks.

Convention Over Configuration :

Rails heavily emphasizes on “Convention over Configuration.”  What is meant by this is if one follows suggested naming conventions, it allows one to write minimum amount of code to get the application running. Unlike other languages which focus on the need of heavy configuration, Rails has set rules to ease up working with the application. These convention help expedite development, keep the code readable and concise and allow an easy navigation inside the application.

Metaprogramming :

In other frameworks, extensive code generation is the norm stretching the web development process to months. Ruby employs metaprogramming techniques which is the method to write programs using programs. Because of this, Ruby is able to build applications faster and much easier.

Active Record Framework :

Since, Rails is object oriented framework, it introduced the Active Record framework, which means objects are saved in the database and the Active Record automatically searches, selects the objects and attaches them to the domain object using metaprogramming feature.

Automated Testing :

Rails provide built-in testing to automatically test and also provide supporting codes named as harnesses and other fixtures making test cases easier to write and execute.

Scaffolding :

One of the best features in Rails is scaffolding wherein you can create temporary codes to help get the application up in the earlier stages of development itself and see how all components work together.

Three Default Environments :

Rails provide you with three default environments from development, testing, and production. All the stages behave as they should making the entire software cycle easy to handle.

David Hansson created Rails to improve programmers’ happiness and increase overall productivity without sacrificing the code quality. Rails helps you create a full-stack web application quickly and without breaking any sweat. With so many benefits, it’s no wonder Rails has gained so much popularity over the years.
