Hi, I''m creating a list of ingredients on a page. When the user clicks the ''Add Ingredient'' button a record gets added to the db and the ingredient gets added to the page. On the page, each record is represented by a <div> with three <span>s inside. One of the <span>s has a link_to_remote to ''delete'' the ingredient. When the link

I''m trying to replicate the "green-bar" effect used in the Depot app using Ajax. And I''m almost there ;-) I''m about to set off on the last stage and would appreciate any advice that would set me off in the right direction. On the page, each record is represented by a <div>. Each <div> has id = "item#{record.id}" with class = either

Hey guys, Does anyone have any wisdom to share on the subject of speccing Rails layouts? Most of it''s plain old view specs stuff, but are there sensible ways to verify things like the yield call?

For instance: //Returns all the posts into a collection called posts @posts = Post.find(:all) //Returns a specific post based on an id @post = Post.find(params[:id]) //How can i return the next

Hi, This seems simple but I cant get it to work... I have a table with 4 or 5 columns and 20-30 rows. I''d like to have the ability to click anywhere in a particular row to fire an action, such as bringing up a "Details" page for the clicked row. This would eliminate the need to generate a "Details" link at the end of every row, which is what I have now and looks

Hi guru''s out there, Im happilly coding my first rails app, and all goes well. I find myself manually coding in a particular field all the time (company_id), that relates the contact to a company.

This seems like it must have been asked before - I really _did_ try to find it in the archives, so my apologies if it''s already out there. Utilizing ActiveRecord, I would like to specify a prefix for the column names in my table. For example, in ''Recipe 16 Integrating with Legacy Databases'' (Rails Recipes, from PragProg, by Fowler) they deal with integration with a

Greetings! I''m new to Ajax and am trying to get a basic app working as a vehicle for learning it. The app is an extension of the cookbook tutorial. My intent is to be able to add a list of ingredients for a recipe. The page to add ingredients uses Ajax. As ingredients are added to the page they''re displayed in a "green-bar" format like that used in the Depot

I was looking over some of my specs. I was thinking that the following: @game.should_receive(:name).and_return(''The Battle for Blaze'') @game.should_receive(:people).and_return(5000000) @game.should_receive(:activated).and_return(true) Would it look cleaner if I could do this instead? @game.should_recieve_and_return( :name => ''The Battle for Blaze''

I''m trying to use the select helper but do not need to pass the values back to an object because this is just used as a param value. Everywhere I''ve looked I see that the form field helpers require an object name. I''ve tried omitting the name but I get an error telling me I have two few paramaters. (2 out of 3) Other than typing out the HTML myself (because the

Greetings! I''m trying to update a set of records from the same model on one form. The AWD book gives an example on p.356 but I guess I''m not understanding it.

Hi, I''m trying to create a blank input form with a header and many item lines. I would like to build the item lines dynamically ie not hard code up to 100 lines into my form.
