Ruby On Rails Relationship Between Model, View, And Controller


Ruby On Rails Relationship Between Model, View, And Controller

I wish this helpful for you For a great explanation of MVC, check out Jeff Atwood's post: http://blog.codinghorror.com/understanding-model-view-controller/
Now as for your app, one controller is just fine for displaying User's profile pages. What you should do to ensure security is that for the UsersController#show action (profile page) you should validate that it is the current user, otherwise redirect, or show error message, or show the editable page, etc.
code :
@user = User.find(params[:id])
if current_user != @user
  render :show
else 
  render :self_profile
end
@user = User.find(params[:id])
if current_user != @user
  @authenticated_user = true
end
render :show
<% if @authenticated_user %>
  #Edit button here, takes you to the settings page
<% else %>
  #Follow button here
<% end %>

In MVC frameworks (such as Ruby on Rails), does usually Model spell as singular and controller and view spell as plural?

I wish this help you Generally, Rails has a very specific format for naming models, controllers, and views that is not necessarily the only way to accomplish the task. The Rails tradition is:
Models are in singular form (ie. Story) Controllers are in plural form (ie. Stories) Views are sorted by folder according to the name of the controller (ie. stories/show.html.erb)

wish helps you You can do what you need with the Nested Attributes feature in Rails http://guides.rubyonrails.org/2_3_release_notes.html#nested-attributes
Check out the form helper for it here http://api.rubyonrails.org/classes/ActionView/Helpers/FormHelper.html
code :
class User < ActiveRecord::Base
  has_many :quests
  accepts_nested_attributes_for :quests
  ...
end

class Quest < ActiveRecord::Base
  belongs_to :user
  ...
end
<%= form_for @user do |f| %>
  UserAttrA  : <%= f.text_field :a_user_attribute_a %>
  UserAttrB: <%= f.text_field :a_user_attribute_b %>
  <%= f.fields_for :quests do |qf| %>
    QuestAttrA  : <%= qf.text_field :a_quest_attribute_a %>
    QuestAttrB: <%= qf.text_field :a_quest_attribute_b %>
  <% end %>
  UserAttrC  : <%= f.text_field :a_user_attribute_c %>
  UserAttrD: <%= f.text_field :a_user_attribute_d %>
<% end %>

I wish this help you An addendum to the previous answers : putting a view concern in the model isn't best practice - it violates SRP. Of course you won't be struck by lightning for that little sin, however you should be aware of that.
Also the alternative would be to keep this basic logic in the view like so with a common one-liner :
code :
%p= company.status ? "Active" : "Inactive"
%p= boolean_to_activity( company.status )

# ... in helpers/some_helper.rb

def boolean_to_activity status
  status ? "Active" : "Inactive"
end

will be helpful for those in need It's a complex subject that you can't be simply told how to do, but I'll try to help a little. Zippie's suggestion is a good one, you should go through a tutorial to learn about the different kinds of relationships.
