ruby-on-rails-3.1

I recently upgraded my application to rails 3.1 and generally everything seems to be working but one thing is driving me insane. I have 2 main js files, we'll call them, application.js and main.js. application.js has my manifest stuff in it and is loading in main.js. That's working fine. My problem is when i'm in development mode and i make a change to main.js, then refresh the page the site doesn't pick up the change. In order to pull in the change I have restart the rails server. I have debug mode turned on in development, but I'm wondering if there's another setting i'm missing? Anyone run

I have two classes: Parent and Child with Child: belongs_to :parent and Parent has_many :children, :dependent => :destroy The problem is that I want to check that there is always at least one child present, so I have a before_destroy method in Child that abort the destroy if it is the only child belonging to its parent. And, if I want to destroy the parent, it will call the before_destroy callback on every child, but when there is one child, it will abort the destroy, so the parent will never get destroyed. How can I tell the child to call the before_destroy callback only if it's not being

I've just upgraded my app on Heroku from Rails 3.0 to 3.1, and I'm trying to make the assets pipeline work. The main issue is that I can read from the heroku log the following kind of lines, for every asset: 2011-09-03T16:35:28+00:00 app[web.1]: cache: [GET /assets/border-a3c571a354b9381740db48aeebfaa63a.jpg] miss If I understand the pipeline correctly, this should not be "miss" for every request I make from a browser, but it should be found in the cache. Reading the Heroku docs you can find this explanation: Rails 3.1 provides an assets:precompile rake task to allow the compilation penalty to

I'm having a bit of trouble getting my asset pipeline setup working with Heroku/Cedar using Rails 3.1.1 I've pushed my application and it launches successfully but there was no message that said "Preparing asset pipeline" and no static assets are being served up. No JS, CSS, or images are able to be found as there is no slug compilation time or runtime asset compilation being done. Any help would be greatly appreciated. They describe what should happen during deployment at this link which I'll summarize below: With a Rails 3.1 application on Heroku Cedar when you git push heroku your assets

<%= link_to "Connect", {controller:"home", action:"connectTo"}, id: "btny" %> This is my link_to helper in view. I want to attach a parameter in this link_to tag so that I can get it in the action connectTo . I'm unable to find correct syntax or way to do it, and unable to understand some answers I found on stackoverflow. How can I achieve this? def connectTo #here i want to get the parameter i pass from link_to from view... end Do not use camel case in variable names and method names in Rails. That's not a convention and will bite you later. Use named path when you can, instead of manually

What is the easiest (is there an easy way?) to use Less (in combination with Sass/Scss) in the rails 3.1 assets pipeline? I want to load a file like foo.css.less like i would do for bar.css.scss I found some wonky solution that does not work for me (haven't tried a lot) : https://github.com/thisduck/ruby-less-js/issues/2 The idea would be to use Twitter Bootstrap in a clean way. Thanks in advance If you only want to use bootstrap, you can do it by including the 'less-rails' and 'less-rails-bootstrap' gems in your GemFile. Then, you can @import bootstrap in your .css.less files: @import
