I am just going through the book and I come across a problem with the code in the app/models: validates_format_of :image_url, :with => %r{^http:.+\.(gif|jpg|png)$}i, :message => "must be a URL for a GIF, JPG, or PNG image" It seems to moan when it''s empty even though I removed :image_url from validates_presence_of. How should I make it optional? Altering the regex? Btw I have th...

Greetings! I''m having a hard time understanding the way Rails handles urls. I''m specifically having real trouble with the image_urls in the Depot app in the Agile Web Development book. If I enter "\image\file.png" in the Add Product page, the image is displayed in the other views and Properties shows http://localhost:3000/images/file.png If I leave off the leading backslash and enter "image\file.png" the...

...Rails 1.1.2. My issue is that I''m overloading the view for LoginEngine to support a file image upload as part of the user record and having a heck of a time doing so. Near the bottom of my new _edit.rhtml file I put in: <tr><td><%= file_field("user", "image_url") %></td></tr> which now displays the upload field as it should when I go to sign up a user. I placed in the actual LoginEngine user.rb model the "file_column :image_url" line just below " include LoginEngine::AuthenticatedUser" and I can see when I...

I have a general question about using a Ferret/Lucene index for grouping results. I am not sure how much of the heavy lifting the index can do for me, so I would appreciate any input. I am using ferret to index some objects that have the following properties: url, image_url, price, tags (space separated tags), created_at I would like search the index for any documents that match a specific tag. The way these results will be processed is as follows: Each URL must be unique in the results. If there are duplicates, I would like to merge the results using some fuzzy m...
