I have an application that uses the Paperclip plugin for image upload. Now that app should get deployed to an host(heroku) which has a read-only file system. Can I somehow tell paperclip to store the images in the database? ...
I found some information to get action_name within the controller, but I need to know what it is inside my model. I'm kind of second guessing myself and wondering if that's at all something you would need or could get from being within the model, but I'm not sure. Please let me know if there's a way to get something like action_name with...
I want to use my Rails app to send campaign-style emails ("Hi, call your representative! Her name and number are...") that are customized on a per-user basis. Effectively, each user could be seeing a slightly different email. Some of these emails would need to contain link_to's, and other helper functions. I've never used any CMS in Rai...
I was trying to us the acts as wizard plugin and feel like I'm missing a step between what's in the readme and getting the code to actually run. For instance there's nothing about how to setup the routes, what validations are performed between states, if the form is submitted at each step. If anyone has used this plugin, can you please ...
I have an .erb file where I'd like to return the following text: Name <%r> When I render this file, the erb interprets the <% as a ruby code and doesn't render the % signal. I found one way to do this, putting the % signal in a String like this: Name <<%= "%" %>r> But this is very ugly. Is there any other way to do it? ...
I've added a before_create filter to one of my Rails ActiveRecord models and inside that filter I'm doing some database updates. Sometimes I return false from the filter to prevent the creation of the target model, but that is causing all the other database changes I made (while inside the filter) to get rolled back. How can I preven...

I love those simple words such as "Object", "Property", "Value" and would like to use them as Class Names, but seems they are reserved. ( ? ) ROR failed on many things with a model named "Object" Make a prefix doesn't look good, such as CCObject, CCProperty. Is there a way to allow me to use those simple words directly? What I want...

When a user fails login on my Rails app, I'd like to point them to a password reset page: flash[:notice] = "Login failed. If you have forgotten your password, you can #{link_to('reset it', reset_path)}" However, I can't use link_to in a controller. What's the best way to do this without mixing controller and view logic? My best gue...

All/Anyone, Curious what the prevalent Rails idiom is for indicating the success/failure of a particular action to the end user? For example, let's say you have a restful User resource and update is invoked on said User resource; once the update has completed and I've routed the user back to edit.html.erb - I'd like to indicate whethe...

I've got a Rails application in which a small number of actions require significant computation time. Rather than going through the complexity of managing these actions as background tasks, I've found that I can split the processing into multiple threads and by using JRuby with a multicore sever, I can ensure that all threads complete in...
Sorry for the vague title, but this is kind of hard to put into one line. I have a database full of contact information, and I want to be able to put those different contacts into groups which will also be stored in the database. So, maybe I have 2 groups, "coworkers" and "neighbors", I want to be able to see a list of all my contacts...
