I''m working on a RESTful app, and I''ve hit a snag. Here''s a simplified example of the problem. (Excuse me if this example code isn''t strictly correct; I''m typing from memory.)

Hi, I have a bit of a problem with a form in rails. Well, the problem really is me not fully understanding the mechanism of the form_tag, so here''s what i try to do: The idea is to present a some edit fields for some @product attributes and then present a table showing the @product.pieces (pieces for every @product) and to include a "Edit Piece" and "Delete Piece"

When i use button_to or link_to, i can easily request a confirmation dialog with (for example) <%= button_to "Delete this story", { :controller => "story", :action => "delete", :id => @story.id }, :confirm => "Delete story: are you sure?" %> I also want to do this for the submit buttons on my forms, which are

With form_tag submit buttons I use the " :disable_with => ''button label while processing'' " option so that visitors with slow connections aren''t able to submit forms twice.

Hi, it probably is a noob question but I''m confused by this error message: active_support/dependencies.rb:478:in `const_missing'': uninitialized constant Invoice::ApplicationController Situation: I have an InvoicesController with a create method that in turn calls upon a MiddleMan.worker(:billing_worker), which in turn finds an Invoice and calls upon @invoice.print_invoice

I''m trying to use button_to and have it use an image in place of the submit button. I had figured it would work the same as link_to like so: button_to(image_tag("editicon", :size => "16x16", :border => 0), :action => ''edit'', :id => person.id) but this instead displays the image code as the button name. Surely there is a simple way to

I''m calling button_to in my page, and it renders a form with a submit button just fine. But what I''d really like is <input type="img" src="myimage.png" .....> instead of <input type="submit...> button_to doesn''t seem able to do this, :type and :src parameters get ignored. Is there a way to do it? -- Tim Slattery

I have three tables, Invoices, Projects, and Managers. Each manager has many projects. Each project has many invoices. When displaying a list of the invoices, I am using: Invoice.find(:all, :include => [:project]) Since the list shows information from the project table.

Hi all, I am trying to use in RStudio the latest code given in https://github.com/systematicinvestor/SIT/blob/master/R/bt.test.r, which seems to work fine but with the following warning for download limits (one for each of the tickers).

Greetings, I''m looking for suggestions on how to simplify getting customer addresses on a form: I''m jumping between controller and view several times; alternating between rhtml and rjs, in order to display customers and their addresses on an invoicing form.

I am building an invoicing system but cannot use the auto_increment field to determine the invoice number (because they are running 3 different companies off the one system.
