So it looks like a Rejected-By-UrlScan issue

URLScan is configured to reject certain requests. URLScan.ini

Another email to my providers openhost.co.nz who turned off URLScan for me.

RoR Thoughts so Far

( Ruby on Rails )

The last week of looking at RoR:

Does all the plumbing if you follow the convention
Amazing how little code you need to write
The important stuff for CRUD apps is all there – validators, db relationships, CRUD functionality
The ORM works
Fast to develop!

In summary this look like a wonderful technology for putting together CRUD based business apps fast.

Shared hosting seems to be harder than .NET / PHP, however heroku.com is a great free resource.

Commercially speaking I think it would work very well in an enterprise where there is a need to develop apps fast (when isn’t there!) that do not require huge performance (I would argue that most apps I’ve worked on would be well suited in RoR).

RoR Multiple Tables

( Ruby on Rails )

ruby script/generate scaffold flight departure:datetime arrival:datetime destination:string baggage_allowance:decimal capacity:integer

ruby script/generate scaffold seat flight_id:integer name:string baggage:decimal

rake db:migrate

What we want is a form that has the flight info on it, then the ability to add a new seat booking.

Partials

Coppied seat/new.html.erb into flight/show.html.erb file rendering as a partial

_new_seat.html.erb

Changed:

<% form_for(seat) do |f| %>
<%= f.error_messages %>


 <%= f.label :flight_id %> 
 <%= f.text_field :flight_id %>


 <%= f.label :name %> 
 <%= f.text_field :name %>


 <%= f.label :baggage %> 
 <%= f.text_field :baggage %>


 <%= f.submit 'Create' %>

<% end %>

the form_for(@seat) to (seat) to become a local variable to the partial. This is good practise.

called the partial from flights/show.html.erb as

<%= render :partial=>"new_seat", :locals=>{:seat=>Seat.new(:flight_id=>@flight.id)}%>

<% form_for(seat) do |f| %>
<%= f.error_messages %>
<%= f.hidden_field :flight_id %>

We also need a partial for the seat list

however this is bad as its displaying the seats for all flights

Connect the models together

means we don’t need to use finders.. it works automatically.

class Flight < ActiveRecord::Base
has_many :seats
end

then when rendering out the listing of seats we can pass in the array in show.html.erb

<%= render :partial=>"seat_list", :locals=>{:seats=> @flight.seats}%>

in the model:

belongs_to :flight
    def validate
        if baggage > Flight.find(flight_id).baggage_allowance
            errors.add_to_base("You have too much baggage")
        end
        if flight.seats.size >= flight.capacity
            errors.add_to_base("The flight is fully booked")
        end
    end

another custom validator in the seat model

if flight.seats.size >= flight.capacity
errors.add_to_base("The flight is fully booked")
end

**TO DO put in a validator that checks there is a number for baggage

RoR – Database Finders – Fix The Scaffold

( Ruby on Rails )

ruby script/generate scaffold client_workout client_name:string trainer:string duration_mins:integer date_of_workout:date paid_amount:decimal

rake db:migrate

Problem is that the scaffolding app doesn’t do exactly what we want.

what we want is just the listing for Lenny Goldberg ie a filter.

Creating a Form with no Model

instead of form_for

<% form_for(@ad,:url=>{:action=>'update'}) do |f| %>
Name <%= f.text_field :name %>
Description <%= f.text_area :description %>
Price <%= f.text_field :price %>
Seller <%= f.text_field :seller_id %>
Email <%= f.text_field :email %>
Img url <%= f.text_field :img_url %>
<%= f.submit "Update" %>
<% end %>

we use form_tag

<% form_tag "/client_workouts/find" do%>
 <%= text_field_tag :search_string%>
 <%= submit_tag "Search" %>
 <% end %>

by putting in dave into the search box, we can see it coming through in the controller by using puts to output to the console.

So we only need those records where client_name = the search string.

def find
puts params[:search_string]
@client_workouts = ClientWorkout.find_all_by_client_name(params[:search_string])
end

The framework creates finders for each attribute.. eg find_all_by_client_name.

and I just wired up to a find.html.erb file.

however we want to search on trainer as well ie where client_name=”Lenny Goldbery” or trainer = “Lenny Goldberg”

@client_workouts = ClientWorkout.find(:all, :conditions=>["client_name = ? OR trainer = ?",
params[:search_string], params[:search_string]])

The crowd goes wild! Can filter on client_name or trainer.

Validators

A number:

class ClientWorkout < ActiveRecord::Base
validates_numericality_of :paid_amount
end

Mandatory:

class ClientWorkout < ActiveRecord::Base
 validates_numericality_of :paid_amount
 validates_presence_of :trainer
 validates_presence_of :client_name
end

Doing it on custom code:

class Ad < ActiveRecord::Base
validates_presence_of :price
validates_presence_of :name
end

def create
 @ad = Ad.new(params[:ad])
 if @ad.save
 redirect_to "/ads/#{@ad.id}"
 else
 render :template => "ads/new"
 end
end

<% form_for(@ad,:url=>{:action=>'create'}) do |f| %>
 <%=f.error_messages%>

Head First Rails – Creating an App From Scratch

( Ruby on Rails )

here is how we do it from scaffolding:

Symbols and Strings

<%= f.label :seat_id_seq %> This is a symbol. They always start with a colon. Generally used to name things. Mostly interchangeable with strings.

<%= f.label “Seat #” %> This is a string.

Add a column to the DB

to add the database we:

ruby script/generate scaffold ticket name:string seat_id_seq:string address:text price_paid:decimal email_address:string

to add a row:

ruby script/generate migration AddPhoneToTickets phone:string

important bit is Add…To…

then

rake db:migrate

then changed the 4 view to display the new field.

Starting From Scratch

The scaffolding can create too much code! Here is an app just generating 1 page to start with (a show page)

ruby script/generate model ad name:string description:text price:decimal seller_id:integer email:string img_url:string

models have singular names eg ticket, ad

Controller

ruby script/generate controller ads

controllers have plural names

Routes

map.connect '/ads/:id', :controller=>'ads', :action=>'show'

use the ads_controller.rb, and the show template.

View

show.html.erb

Name:<%= @ad.name %>

Index Page

controller:

def index
@ads = Ad.find(:all)
end

index.html.erb

<% for ad in @ads%>
<li><a href="/ads/<%= ad.id%>"><%=ad.name%></a></li>
<% end %>

route

map.connect 'ads/', :controller=>'ads', :action=>'index'

Layouts

images into public/images

stylesheet into public/stylesheets

apps/views/layouts/ads.html.erb

Post New Ads Online

routes

map.connect 'ads/new', :controller=>'ads', :action=>'new'
map.connect 'ads/create', :controller=>'ads', :action=>'create'

viewff

ads/new.html.erb

and the form will be submitted to:

ads/create

RoR Text Editor

Am trying http://www.e-texteditor.com/

ctrl shift p – toggle between project view and editor view

http://www.e-texteditor.com/wiki/index.php/Projects#Keyboard_navigation – keyboard shortcuts

Create Form Helper

Rails can create forms that are associated with model objects. so in new.html.erb

<% form_for(@ad,:url=>{:action=>'create'}) do |f| %>
Name <%= f.text_field :name %>
Description <%= f.text_area :description %>
Price <%= f.text_field :price %>
Seller <%= f.text_field :seller_id %>
Email <%= f.text_field :email %>
Img url <%= f.text_field :img_url %>
<%= f.submit "Create" %>
<% end %>

eg this comes out as:

<b>Name</b><br /><input id="ad_name" name="ad[name]" size="30" type="text" />

so when the submit button is pressed, this routes back to the create action in the AdsController.

Controller

def new
      @ad = Ad.new
end

def create
      @ad = Ad.new(params[:ad])
      @ad.save
      redirect_to "/ads/#{@ad.id}"
end

note: create an empty ad object before passing onto new

and we have an automatic redirect to the listing

otherwise could have commented out and it would go automatically to create.html.erb:

Edit a Record

routes add in

map.connect 'ads/:id/edit', :controller=>'ads', :action=>'edit'
map.connect 'ads/:id/update', :controller=>'ads', :action=>'update'

controller add in

def edit
      @ad = Ad.find(params[:id])
end
def update
      @ad = Ad.find(params[:id])
      @ad.update_attributes(params[:ad])
      redirect_to"/ads/#{@ad.id}"
end

view add in

<% form_for(@ad,:url=>{:action=>'update'}) do |f| %>
Name <%= f.text_field :name %>
Description <%= f.text_area :description %>
Price <%= f.text_field :price %>
Seller <%= f.text_field :seller_id %>
Email <%= f.text_field :email %>
Img url <%= f.text_field :img_url %>
<%= f.submit "Update" %>
<% end %>

Security

in the AdsController

before_filter :check_logged_in, :only => [:edit, :update]

private
    def check_logged_in
        authenticate_or_request_with_http_basic("Ads") do |username, password|
            username == "admin" && password == "secret"
        end
    end

Delete

Just calling a single action on the controller called destory which then redirects back to index.
