similar to: trying to create asset management app having trouble with edit page

I have been working on a project based on Michael Hartl''s book Ruby on Rails Tutorial in order to try to teach myself Ruby on Rails. However, when it tries to render a form designed to allow a user to submit a small message, I get an error saying, "undefined method `model_name'' for NilClass:Class". It says the error is at line 1, which is "<%= form_for

I''m going through Michael Hartl''s Rails tutorial, and I am happy to report that (as of the end of section 7) I''m able to get things working. (That said, I skipped the section on automated testing, as Hartl warned that automated testing is the most likely part of his book to become outdated.) There is a heavy emphasis on the "bundle exec rspec spec" tests.

i've defined an asset host for my Rails app and all files uploaded through it are accessed via the asset host. How should i access the config object in order to generate correct urls for these files using link_to? _______________________________________________ Rails mailing list Rails-1W37MKcQCpIf0INCOvqR/iCwEArCW2h5@public.gmane.org http://lists.rubyonrails.org/mailman/listinfo/rails

Ok I would love to work out how to use the new Raisl 3.1 Asset Pipeline with SCSS variables, mixins etc and being able to use the asset_path tag. What I have so far is this. Im my application.css.scss I have the following. *= require_self *= require layout *= require home This works fine with using the asset_path helper and variable within layout ie, // layout.css.scss.erb

Hi, I''ve been trying to incorporate https://github.com/wycats/rack-offline into my app. I followed the example in the readme that shows how to cache application.css and application.js files and that works. When I go to my browser in production mode, though, and turn off my network connection, then reload the app, the app is reloaded successfully, except for the images. I think I

Hey, in my `application.html.erb`, I have this line: <%= stylesheet_link_tag ''application'' %> which should compile through the asset pipeline and link to the application.css (which does a `require_tree .`). In development mode, I''d expect a <link ... href="/assets/application.css" /> This file is actually delivered by, for example, the

Hi I am thinking to hide warning that is ”Served asset /application.css - 304 Not Modified”. How can I fix something if I change the settings?

Hi guys, I would like to know how to get the image_path in production environment without the asset host (using rails 3.1). There is the image_path helper that returns the image path with md5 and (if set, and it is set) the asset host, but we have not found a way to get the path without the host. Does anyone know how to do that? Bruno Grasselli Blog: http://brunograsselli.com.br Twitter:

I need to reference the full url of an image stored in the assets, this url is passed to fancy box to open it I build the image path in helper and it get the path "ceramics/big/c0d0.jpg" "ceramics/big/c0d2.jpg", ... but I need to get the full url to these image asset_path("ceramiques/big/c0d0.jpg") => "/assets/ceramiques/big/ c0d0.jpg" but there

If I use the asset pipeline my auto width margins don''t work. The content box is shoved far left. If I disable asset pipeline it works as expected. Any ideas?

Hi all, I just submitted a patch that would allow you to pass a proc to ActionController::Base.asset_host rather than just using a %d wildcard (e.g. assets%d.example.com). Basically this frees you from the hard-coded assumption that you have 4 hosts numbered 0-3 and also allows you to do smarter things depending on the asset (e.g. images from a particular domain, stylesheets from another). The

Is it possible to add another asset tag helper (ActionView::Helpers::AssetTagHelper ) ?? coz i''m using the ActionController::Base.asset_host = "http:// assets.example.com" for my static files.. and I want my app to get video files from that host too.. but the thing is only images, javascripts and stylesheets have the asset tag helpers with them.. what if i wanted videos? any

https://github.com/NV/chrome-devtools-autosave doesn’t play nice with Asset Pipeline. https://github.com/NV/chrome-devtools-autosave/issues/27 The culprit of the problem is in the asset’s URLs. I cannot decipher a file path by its URL. For instance, /assets/main.css?body=1 could be either app/assets/stylesheets/main.css, lib/assets/stylesheets/main.css or vendor/stylesheets/main.css. To fix

I am using Rails 2.1 and HAML for some, but not all, of my templates. All of the self-closing asset tags (<link>, <img>) output by the rails asset tag helper methods are not being closed at all, thus rendering my pages as invalid XHTML. Has anyone else dealt with a similar problem? I am completely out of ideas, so if you have any suggestions, by all means, fire away. Thanks. -- Posted

Perhaps I''m completely missing something, but... It seems like ActionView::Helpers::AssetTagHelper#compute_public_path keeps a cache of all public paths along with the appended asset id. However, this means that applications (in this case, Facebook) that cache based on the name of the file will never pull the new file if it''s been modified. Would it make sense to either: (a)
