# Full Speed Ahead 
I am rolling after submitting my most recent Ruby on Rails project for Flatiron Bootcamp. I was tasked with building an app with complex relationships such as a many-to-many relationship with several other project specifications. This project management app was just the challenge I needed to solidify my knowledge in Ruby after finishing a full web application in the Ruby Sinatra framework a month ago. 

# Off The Rails 
Having just finished up with Sinatra, I really had to put in much more work to wrap my head around Rails. Sinatra was very lightweight and the barebones design is all you need for a simple app. Rails however is a very opinionated and useful framework to get large prototypes up and running fast. Learning was not as fast. I spent plenty of time discovering the Rails way and came to appreciate Convention over Configuration. 

```
# devhub/app/views/projects/new.html.erb

<%= form_for [@user, @project] do |form| %>
    <%= render partial: "form", locals: {f: form} %>
<% end %>

# devhub/app/views/projects/_form.html.erb

<div class = "container">
    <%= f.hidden_field :user_id, :value => @user.id %>
    <%= f.hidden_field :project_id, :value => @project.id %>
    <strong><%= f.label :name %></strong>
    <%= f.text_field :name, class:"form-control" %><br>
    <strong><%= f.label :description %></strong>
    <%= f.text_area :description, class:"form-control" %><br>
    <strong><%= f.label :due_date %></strong>
    <%= f.date_field :due_date, class:"form-control" %><br>
    
    <%= f.submit 'Submit', class: "btn btn-primary" %>
</div>

```

# Now we're moving?

Whoa! that's a lot of magic. The Rails documentation was my go-to for understanding all the built-in helpers that make Rails go. Rails' follows the MVC architecture and this view was implicitly rendered from my Controller action: 

```
# devhub/app/controllers/projects_controller.rb

def new
   @project = Project.new
   @user = current_user
end 

# => Rails follows RESTful convention and assumes I need a view for this action based on the name **def new** and renders new.html.erb for me.

```

# Well-Oiled Machine

Next, my new view template file takes advantage of more Rails magic, ERB(Embedded Ruby), and Rails Partials to dynamically render to totally different forms to submit. 

``` 
# devhub/app/views/projects/new.html.erb

<%= form_for [@user, @project] do |form| %>
    <%= render partial: "form", locals: {f: form} %>
<% end %>

# => This code renders a form to create a new project!

# devhub/app/views/projects/edit.html.erb

<%= form_for [@user, @project] do |form| %>
    <%= render partial: "form", locals: {f: form} %>
<% end %>

# => This code renders a form to edit a project!

```

# Nuts & Bolts 

These two identical snippets of code conditional will render a separate form based on conventional controller actions. Rails will do this for us: It recognizes **def new** to return the new project form and **def edit** to return the edit project form. These forms are glued together by this piece of code called a partial `<%= render partial: "form", locals: {f: form} %>` that will provide a two fully function forms for us. 


# This is my stop
