Hi, I have a transaction in which a duplicate key exception is being thrown by MySQL. I assume this happens when I try to do a save. The problem is that before the save, I do a destroy on another object as part of the transaction.

Hi, I''m calling a helper I''ve written - format_time() that is called from my views with a given time that was selected from my database and was returned to the view via an instance variable. When I call format_time from a partial, I see that I get some kind of String error and the partial won''t render. Basically, the object being passed in to format_time is already a

Hi, I have one minor issue. I''m trying to check whether a directory is empty given some path to the directory. My code does the following: if(File.directory?(dirpath)) # dirpath = public/images/1 if(File.zero?(dirpath)) FileUtils.rm_rf(dirpath) end end The problem is, while testing this, if I put a file in the directory and run the above code, it still ends up deleting the

Hi, I''m able to upload files onto my webserver filesystem but I had a question regarding how I''d go about accessing them using the <img src="..." > tag. If my files, i.e pictures, are being uploaded to public/images/<dir>/filename.jpg, then should I store the entire path, or just the picture name in my database table? I would imagine storing just the

Hi all, For various reasons I need to have foreign keys with not null constraints. Eg: create_table :people do |t| t.column :name, :string t.column :household_id, :integer, :null => false end create_table :households do |t| t.column :name, :string end add_foreign_key_constraint :people, :household_id, :households, :id So the people table has a foreign key into

Hi, I''d like to be able to store the absolute path for a file so that I could use <img src = "...." > and give it the path to the file I''d like to display.

I seem to be missing something trying to use ''validates_inclusion_of'' to validate a foreign key and was hoping some one could piont out my mistake? The problem seems to be that Order.find_all.collect is not returning an array that contains the order_id, if I replace it with a hardcoded array everything works as expected. The model: class OrderItem < ActiveRecord::Base

Hi, I want to be able to have several layouts within each other so that I don''t have to keep repeating the layout code for one, in another. An example would be having a layout for the title of your web page and then having an embedded layout for the body portion in which the HTML for whatever view gets displayed. Is this possible?

Hello, I''ve been using InstantRails 1.0 that has ruby 1.8.4 and rails 1.0. Some of you might know that the RMagick package does not work with ruby 1.8.4.

Hello, My question has to do with a form resubmit problem. Say for example a form is submitted and within that form, a picture is uploaded. If the user presses the Back buttom and gets back to the form submission sheet, and then clicks on resubmit, once again, the same data is populated into my tables wasting space (another picture upload for no reason in a separate row). Now, I know there are
