Body
I am building a small application in RoR that has a form asking for a URL. Once the URL has been filled in and submit button is pressed I have downloaded a web-scraping plugin scrAPI(which is working fine) which gets the of URL and creates a record in db with title. My issue right now is that I am able to make the whole thing work if the URL is valid and scrAPI is able to process it. If a URL entered does not work it gives this "Scraper::Reader::HTTPInvalidURLError" which is expected, but my knowledge of working in Model is preventing me from handing that error in a correct manner. Controller: <pre><code>#controller class ArticleController < ApplicationController def savearticle @newarticle = params[:newarticle] @link = @newarticle["link"] @id = @newarticle["id"] Article.getlink(@link) success = Article.find(:last).update_attributes( params[:newarticle] ) if success render :partial => 'home/articlesuccess' else render :partial => 'home/articlebad' end end end # model require 'scrapi' class Article < ActiveRecord::Base attr_accessor :getlink def self.getlink(link) scraper = Scraper.define do process "title", :title => :text result :title end uri = URI.parse(link) Article.create(:title => scraper.scrape(uri)) end end </code></pre> How to: 1) Handle the Scraper::Reader::HTTPInvalidURLError properly, so text could be returned to view with proper error. 2) I would also like to know how I can return 'uri' from model and use it in the controller or view. 3) Also, I would like to return the ID of the Article created in Model so I can use that in the controller instead of doing find(:last) which seems like bad practice.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
