how to get the model name of an AR instance

I have a polymorphic class Event

class Event < ActiveRecord::Base
  belongs_to :taskable, :polymorphic => true

so an event.instance has  :  event.taskable_type    and
event.taskable_id
i.e.   event[:taskable_type] = "Project"  event[:taskable_id] = 2

Is it possible to localize the  taskable_type  ( "Project")  using
Model.model_name.human ?   taskable_type is a string...

I tried to get it from the instance ,
event.taskable.model_name.human, but model_name is not an AR instance
method
( NoMethodError: undefined method `human_name' for #<Project...>

Will_Paginate

Hi Guys,
In my application I created this method:

  def self.find_paginated_posts_by_post_type(post_type,page=1,query="")
    if query.empty? == false
      query = "%#{query}%"
    else
      query = "%"
    end
    result = includes(:user).
             where(['post_type_id = ? AND title LIKE ?', post_type.id, query]).
             order('created_at DESC').
             page(page)
   return result
  end
 

this method is returning an ActiveRecord::Relation Object. So, when I use
will_paginate method my application throws an exception :

undefined method `total_pages' for #<ActiveRecord::Relation:0x007f94581e7848>
How can I fix it?
Thx

Bruno Meira

Cucumber coverage -- how?

Hello all. I am trying to see how much of my code is covered by Cucumber
features/scenarios. The feature steps are actually using the
browser/views to tests, so they are not directly instantiating
controllers, etc.

My question is, is there a way using SimpleCov or any other coverage
tool to give me a report? Please note that I am NOT directly
instantiating controllers from my steps, rather using the
browser/views/capybara.

I would appreciate any and all replies! Thanks.

S

Differing Schemas (MySQL / RDS)

I'm using AWS RDS / MySQL for my DB layer.


I ran migrations on my sandbox environment, and then on my production environment, and I'm getting slight differences.  I'm fairly new to MySQL.  The differences are these AUTO_INCREMENT fields.  Should I take the difference to indicate that I've messed up my migrations and should start fresh?  Or is it possible for the same migrations to result in different schemas?

Schema's dumped using mysqldump:
mysqldump -u xxx -pxxx dbnamexxx --no-data=true --add-drop-table=false -h dbhostxxx > dbnamexxx.schema

then diffed
50c50
< ) ENGINE=InnoDB AUTO_INCREMENT=10 DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci;
---
> ) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci;

WHERE first_name LIKE ? OR last_name LIKE ? GROUP BY first_name,
last_name, middle_name",  params[:first_name], params[:last_name] ])

Photo Gallery

Hi there,

I need a photo gallery and was thinking to use picasa or flickr to do
it. Is there a gem or pluging that I could use with rails 2.3.8?

Thanks,

Pedro

how to rename a method of a module.

I'm using the gem bootstrap-will_paginate and inside this gem there is
the initializer:

require 'will_paginate/view_helpers/action_view'

module WillPaginate
 module ActionView
   def will_paginate(collection = nil, options = {})
     options, collection = collection, nil if collection.is_a? Hash
     # Taken from original will_paginate code to handle if the helper
is not passed a collection object.
     collection ||= infer_collection_from_controller
     options[:renderer] ||= BootstrapLinkRenderer
     super.try :html_safe
   end

.............

So when I call will_paginate it's rendered using BootstrapLinkRenderer.
I want to rename the method name will_paginate in, for example
bootstrap-will_paginate, so that I can use will_paginate with its own
render and bootstrap-will_paginate with BootstrapLinkRenderer.
How can I do this?
