Hi all - i'm trying to get memcached and the Interlock plugin working with a new rails app. The weird thing is that they both work fine in another app on the same machine and i can't figure out the difference that's stopping this app. The new app is rails 2.3.4 and the old one is 2.2.2 in case that's a factor.
When the app starts, i...

Hi, in Rails using the Polymorphic version of Paperclip, the default saving technique means that files with the same name overwrite each other. Including the :id in the path and URL doesn't work as it just overwrites the earlier file with the old :id.
I've tried interpolations using a time-stamp, but it just looks for the current time w...

A user can import data into our website from a file.
The data normally contains several hundred Items (Item < ActiveRecord::Base).
Although the validations help, they cannot solve the problem of sanity-checking the content.
For that we would like to have a test mode.
Could we use a temporary Items table for this with Rails/MySQL, and,...
Hey all,
All I wanted to do was convert a haml file to erb. After doing so, i get
an undefined method `render_sequence_nav' error message. Even though no
such error happened when it was in haml format. In the haml file, there is this line:
#fields << render_sequence_nav(sequence_info, students_path)
fields << render(:partial => ...

What do you think the best way to generate a random DateTime in rails is? I am currently using the random_data gem to produce a random date, but it defaults all times at 12:00 AM. Here is an idea of what I'm trying to do (it's for a seeds.rb file). Also, maybe a random price within a certain range? I'm thinking I would need some sort of...

Where 123 is the id of the list. What I would like to do is add the title of the list the url so it it more informative(for google or whatever). So I would like it to look like:
www.mysite.com/lists/123/title-of-list-number-123

I use the active record find_or_intialize (similar to find_or_create) in a few places, which leads to annoyingly long non-breakable method names. For example, "find_or_initialize_by_topic_id_and_publish_date_and_publist_id" really messes up my formatting. I know with the normal find method I can supply all this stuff as parameters. Is th...
