问题 I'm creating a mobile site next to our normal html site. Using rails 3.1. Mobile site is accessed in subdomain m.site.com. I have defined mobile format (Mime::Type.register_alias "text/html", :mobile). In ApplicationController I have "before_filter :mobile_site_before_filter" that recognizes mobile site and sets format according to it. def mobile_site_before_filter if request.subdomains.first == 'm' original_format = request.format request.format = :mobile @mobile_site = true request.formats

So Im playing with CoffeeScript, Rails 3.1 all the good stuff. I have a resource with all the usual routes index, show, create, edit, update, destroy.

Errno::ENOENT (No such file or directory) in amazon-s3

由 南笙酒味 提交于 2019-12-01 05:53:03
I have application which is deployed to heroku using amazon s3 posting images to buckets.This works perfectly fine. But when fetching same image it gives error: Errno::ENOENT (No such file or directory showing path s3.amazonaws.com/bucket_name/app/public/messages/images/000/000/061/thumb/images.jpeg?1362410115) Same path copying and pasting in browser's url doesn't work. If I am using bucket name as end point it works ie, with following path /bucket_name.s3.amazonaws.com/app/public/messages/images/000/000/061/thumb/images.jpeg?1362410115. But I dont know how to configure this url in my model.

How to use dojo toolkit with rails 3.1 asset pipeline and coffeescript?

由 安稳与你 提交于 2019-12-01 05:50:15
I'm trying to use dojo-toolkit as the JS framework on a rails 3.1 app, but I'm struggling to incorporate the dojo require structure with the sprockets require and coffeescript. It seems dojo expects the JS files on the disk, but I guess they're created on the fly from coffeescript. Wondering if anyone has an idea of how the two require-s can co-exist. karellm I recently had to install dojo with rails 3.1 and the asset pipeline. Here are the steps I followed to make it work: 1/ Include Dojo Put the dojo SDK under vendor/assets/javascripts so you get the dojo, dijit and dojox folder in it.

Image showing as blank in Rails 3.1 on Production (Heroku)

由 陌路散爱 提交于 2019-12-01 04:03:09
I recently updated my Rails to 3.1. Here's a part where I added: <%= asset_path('logo_symbol.png') %> This renders /assets/logo_symbol.png which works perfectly fine in development environment. However, when i push the code to production on heroku, it shows a broken image, with the url: assets/logo_symbol-135ddc8db2c9b59f032bed7db520137a.png . I am guessing the new name is for the reason of some optimization. It is however interesting to note that when I go to the assets/logo_symbol-135ddc8db2c9b59f032bed7db520137a.png url on production, I see a blank page, but when I change that url to
