similar to: MVC design good/bad

Hello folks, I use to think that a relational databases without foreign keys constraints enforced strictly by the RDBMS were no good, piece of crap, data junk. However, I''ve also learned the hard way that FKs constraints imposes serious difficulties when moving data around, specially between different DBs, or for loading test data or for upgrading DBs schemas, or for porting DBs

Should I create a separate controller for each model or should I use 1 controller for all models? Having 1 "admin" controller for all backend stuff seems logic to me, but when I scaffold it rather makes 1 controller per model. I''m fairly new to the MVC pattern, so what''s the prefered way of doing it? I''m also wondering if the API is up to date? When

find_by_sql BREAKS THE OOP BEAUTY and perhaps we can solve that. NAMING CONVENTIONS can perhaps make find_by_sql much more clever. lets imagine that relation: publishers <- books <-> authors_books <-> authors -> universities (can''t find something else than university for that last association :) ) imagine we want to fetch every book and every associated

Hi everyone I''m Maximiliano Guzenski from Brazil and I am programing on ruby on rails only a couple of months. I read a lot of books and articles about it but I could not clarify some doubts about design patterns: 1) Is it really good put some sql command on controller? because all articles that I see use sql into controllers, like: # my controller @categories = Category.find

Hi all, A newbie with Ruby on Rails - and programming in general - I''m working on a few Flash and PHP projects as well. Partly to make my work more efficient, partly to gain a better understanding of system architecture / design patterns, I''ve been trying to use the MVC pattern in database-backed Flash / Actionscript development as well. I think / hope that I''m

Hello I have been using LAMP for the last 6 years and i am now finally making the choice to move over to RoR. This MVC stuff is all very new to me. As i have no trouble understanding ruby code... or any code for that matter.. my challange comes in getting my head around the MVC stuff. Is there any demos articles that you guys have seen that takes a site or a business breif and explains where

Hi, I am starting to learn rails and I went through the guide and a couple of tutorials. Even though I understand controllers or at least I can use them I can''t see yet the whole picture. Why do you need several controllers for a single application? If a controller is just a class whose methods interface with models and views, why not have a single controller for the whole application?

Ok, Here''s my controller: def create trainingplan = Trainingplan.createplan(@params[:startdate], @params[:enddate], @params[:hoursperweek], @params[:programtype]) end My model is: class Trainingplan <ActiveRecord::Base def self.createplan(stardate, enddate, hoursperweek, programtype) stardate = startdate enddate = enddate hoursperweek = hoursperweek programtype

Hello everyone! I have generic views for CRUD operations For example I render(''shared/list'') from controller shared/list.rhtml ... <% for item in @list %> <tr class="<%= cycle ''list-line-odd'', ''list-line-even'' %>"> <%= render :partial => ''item'', :locals => { :item => item } %>

An Account has_many Websites which in turn has_many WebsiteDomains Now I can of course do this: @domains = Account.find(1).websites.find(1).website_domains.find(:all) To get all the domains for Account with id 1 and Website with id 1. I would like to do something like this though: @domains = Account.find(1).websites.find(:all).website_domains.find(:all) IE, get ALL domains for all websites in

Hi, I''m a newbie in both Ruby and Ruby on Rails. I finished the Ruby on Rail Tutorial on Todo list and it was great. But, now I''m trying to understand the logic behind it, that is something that is not obvious on how each one of them ties together. Is there a flowchart that shows how the inner working of Ruby on Rails? In another words, let''s suppose we consider the

I''m going to take another stab at this question (my first one received no replies): I have two models: Author has_many: books Book has_one: author I have two tables: authors id ... books id author_id ... I let the scaffolding fly and it created the CRUD goodness for each model, as expected. However, I want to have only one view/controller "set" for both models; when I

1st: I am a newbie to Rails & to pure OO. Q: I want to use rails for creating a "master-detail" form. page layout will allow users to type in an "expense report header" and as many "expense report lines" as they need to. I understand how to wrap the final submit action using "transaction" to ensure the inserts to the database happen within the same

Just wondering how to best integrate with pagination and still stick to MVC... Say I have a Post model that has a published attribute. I want to show all the recent published posts on a page. My first instinct is to create a method in the Post model called recent that does the find with proper conditions and order, but the problem I have is how do I use that with pagination (which definitely

is a model similiar to a class? and active record is similiar to how Java classes inherit from Object? View is nothing more than an output of a model with HTML? Controller is basically the Main part of the program? -- Posted via http://www.ruby-forum.com/.

Scenario: I''m creating an image file upload service for my web site. As well as saving the actual file I also need to create a database record for the file. I would like to name the file after the record id, but I also need to save some attributes of the image (width/height/mime_type etc) which I can''t discover until after the file is created. The Problem: 1) The id is not

I''m wondering if this is a typical thing. What I''m doing is getting about 5000+ records from a database and displaying all of it on a page. I''ve used the benchmark helper to benchmark the views for that page and that takes about 25 seconds to render that view. Is this pretty typical? What I''m doing is using find_by_sql to get all the values that I need from
