i am reading Agile Web Development with Rails and i have some noob questions about it. i''ve gone through the depot application with hardly any problems and now i''m reading through the chapters that explain some of the deeper facets of rails. on chapter 14 it starts talking about active record. all the sudden, it''s showing examples of how to connect to the database.

Greetings! I could really use some help understanding what Rails puts into the session store related to the objects it creates. I''ve found documentation on how _I_ can put / get info into it, but can''t find the docs on what _Rails_ puts into it. I''ve got a simple app that collects some data from the user, stores it in a db record, allows the user to edit it, display

Many of you probably know the ''depot'' app from the ''Agile Rails development'' book. I have constructed the ''products'' model, the Store-controller, and the ''Cart'' and ''Line Item'' classes. I have told Application-controller about :cart and :line_item: model :cart model :line_item Here''s part of

does anyone know much about resizing different versions of images with file_column? i tried it and everything works fine, but my question is can you do more than just make sizes with a version of image? i''m working on a photo album and i would like to resize the image to a medium size, but create a thumbnail as well and crop anything left to make the thumbnail a perfect square. --

i''m still pretty new to rails, and while i''ve been able to hack my way into having it do what i want so far, i''m not happy with the way my code looks. on top of that, i''m sure that what i''m doing prlly isn''t the most efficient either. one of my biggest problems is probably to do with using relationships and forms together. i''ve

i used the hivelogic article to install ruby on rails to my mac: http://hivelogic.com/articles/2005/12/01/ruby_rails_lighttpd_mysql_tiger everything works great using the script/server command, but isn''t that still using WEBrick? how do i server my apps with lightTPD? i tried following the instructions given here: http://duncandavidson.com/essay/2005/12/railsonlighty but have had no

I''ve been working with ActionMailer for a few days and finally have a pretty good grasp of it. In the book I''m reading, it shows how to send to multiple users or an array of users. Is there a setting or some configuration I can do to send the email to each person separately, or would I just need to loop through each user and send one email at a time? What is the best way to

Hi I am new to the whole Rails/Ruby world as having come from a MS .NET background, but I have followed the Depot example in the Agile Web Dev. with Rails book with relative ease. However as an exercise to see how much I had understood, I thought I would attempt to modify the example a bit and add a Quantity field to the store index so as to pass that value into the cart. I have extended the

i have a copy of the typo source on my desktop that i am going through just to get a better understanding of the rails framework and ruby itself. i''m fairly new to everything so it has proved to be very helpful and very inspiring. i''m stuck on a part though. i was trying to figure out how everything on the sidebar works. i found the components folder and started looking

Newbie, having good luck with Dave Thomas'' book ''Depot'' application until I discovered that changes to one of my .rb class files are not being recognized until I bounce the webrick server. Any ideas on this? Thanks. -- Posted via http://www.ruby-forum.com/.

could someone explain some of the uses for a web service. i''m reading about how to make them, but i''m still not quite sure what they''re good for. i have multiple rails apps that i would like to pass user information back and forth to. i''m not sure if something like this could help me or not. thanks -- Posted via http://www.ruby-forum.com/.

anyone can explain me why in the Agile Depot Tutorial application they use i.product_id to find if a product already exist in the cart, because the cart contains items, each of them references a product. I tried i.product_id like in the tutorial and i.product.i all of these 2 notation works , but i find the second seems more clean??? isn''t it. Any explanation will be fine Regards

Hi, I''m 8+ hours reading and working through the book "Agile Web Development". My brain is now mush :) I have some php experience but that about the extent of my programming experience. Anyway, I do have a question - for those who know the book or those who don''t - The product table has a column for an image link ..i.e. /images/something.gif As part of the exercise

Hello, Im in the process of working my way through the 2.ed of the agile book. As many of you already know, the book goes through the regular development cycle of the Depot application. I have hit a wall when they started talking about the sessions and the exact mechanics of how an item is added to the session. The code looks like this: depot/app/controllers/store_controller: def add_to_cart

First of all id like to say hi to everyone from Argentina, im yet another Depot first-timer. Going through the example, i got to the point where my cart finally runs Ajax-based. And there is a line where Dave says, after all the job is done "You should see the cart in the sidebar update. And you shouldn''t see your browser show any indication of reloading the page. You''ve

The error occured while evaluating nil.roles i am pretty new to rails and

I want to modify and update the items in the Depot - "display_cart". Since the cart is in a session, its a little hard to get at the data. I just want to create a way to change quantities, prices and recalculate. Has someone done this, and could you point me to the right direction. Thanks Chas -- Posted via http://www.ruby-forum.com/.

I''m doing the depot example in the Agle Web development book. I''m getting this error: "undefined method `product'' for #<BigDecimal:331ce70,''0.21E1'',8(8)> " "Extracted source (around line #9): 8: for item in @items 9: product = item.product 10: -%> 11: <tr> 12: <td><%= item.product%></td>"
