Rails 3.1.3 using anchor attribute with link_to tag from posts/index to posts/show/id not working

由 心已入冬 提交于 2019-12-12 08:48:45
问题 I am using a link_to tag on my posts/index view and want to link it to my posts/show/id view with an anchor that makes it scroll down to the comments form. For some reason I can't get the anchor to work. Here is my code: In posts/index <%= link_to 'Add a Comment', post, :anchor => 'comment_form' %> This fails to append the # sign to the end of the link, so it is just localhost:3000/posts/id. I have also tried many variations for link_to, including: <%= link_to 'Add a Comment', post(:anchor =>

Capistrano for Rails 3.1

问题 I am using Rails 3.1 and Capistrano, I get No such file or directory errors for /public/images, /public/stylesheets, and public/javascripts errors. Searching the Internet, I found a number of blog posts suggesting set :normalize_asset_timestamps, false which removed these problems. However, I am not sure if I am doing the right thing since precompile still fails and I am new to Rails 3.1. rake RAILS_ENV=production RAILS_GROUPS=assets assets:precompile still fails on the production server.

How can I display entries in a horizontal table in rails 3.1

由 我的未来我决定 提交于 2019-12-06 09:35:53
问题 I would like to display items for an e-commerce page in Rails, and instead of a standard vertical list table, I would like to the title and images from left to right, about 4 across, then continue the list on as added: ie. Entry 1 Entry 2 Entry 3 Entry 4 Entry 5 Entry 6 .... My first guess is to make a scope for each column- where I could skip entries by a factor of 4, but I would like to know if there is a better solution using CSS or any other trick? 回答1: There's a method on Enumerable

URL of images in JavaScript code using Rails 3.1 asset pipeline?

In CSS files, you can get the proper name of an image asset (with the fingerprint) by using: background-image: url(image-url("rails.png")) but how do you do the same from a JavaScript file?
