When I run rake test , I get error line every time. log writing failed. "\xE2" from ASCII-8BIT to UTF-8 Please guide on this. How to remove this error. You probably have somewhere in your code trying to output string whose encoding is wrong or has some weird characters and the encoding doesn't work. Correct way would be to find the string that results in problems and find out why its in wrong encoding. See encoding and force_encoding in string api ( http://ruby-doc.org/core-2.2.0/String.html ). If you just want to be able to print that line in the log and avoid the error you can do the

Rails dev environment not updating html/css/assets even after restarting server

由 做~自己de王妃 提交于 2019-12-03 23:39:48
I've been developing a site in rails, everything going relatively smooth. Suddenly my changes to the views and assets no longer show up. I change a stylesheet or some html and reload my browser at http://0.0.0.0:3000 and nothing changes. So I restart WEBrick and still nothing's changed. This is even the case if I change an image entirely. The only way to get the new changes is to precompile the assets: C:\Users\me\website>rake assets:precompile C:/Ruby193/bin/ruby.exe C:/Ruby193/bin/rake assets:precompile:all RAILS_ENV=production RAILS_GROUPS=assets Why is it showing production as the RAILS

Print valid, non-escaped JSON in a view with Rails

由 喜你入骨 提交于 2019-12-03 19:52:10
问题 I've tried everything. Every combination of the helpers raw , html_safe to_json including some attempts with ::JSON.encode and CGI.unescape . The issue is that regardless of what I do, I can't print well-formed JSON in a view. It's always HTML escaped. Here's the code in my view: var campaignData<%= "=" + (raw @campaign.to_json) if @campaign %>; In my case, it's always the quotes that are escaped as ". I would just do a gsub on the quotes, but that is a terrible solution to what IMO ought to

How to handle non-root URLs in a singlepage app?

由 风流意气都作罢 提交于 2019-12-03 19:36:52
问题 I try to make a single page app with Rails 3.2 and Backbone.js with pushState option but faced with something that I do not understand. If I load the root URL of the app (/), everything goes right: Rails return an HTML-layout with JS which bootstraps Backbone which makes some XHRs for JSON-entities and renders the content. But if I start using app from non-root URL (e.g. by manually typing it in the browser's address bar) then Rails will try to handle this request using theirs routing rules

由 被刻印的时光 ゝ 提交于 2019-12-03 19:05:22
问题 Every time I deploy my Rails 3.2 project to Heroku, rake assets:precompile is run: $ git push heroku master ... ----> Preparing app for Rails asset pipeline Running: rake assets:precompile Asset precompilation completed (189.17s) ...

Custom text for rails form_for label

由 余生颓废 提交于 2019-12-03 18:32:30
问题 I want to display a label in form_for : <div class="field"> <%= f.label :name %><br /> <%= f.text_field :name %> </div> This generates the label "Name", but I want it to be "Your Name". How can I change it? 回答1: The second parameter to label helper will allow you to set custom text. <%= f.label :name, 'Your Name' %> Use Ruby on Rails Documentation to look up helper methods. 回答2: You can specify custom label text via i18n.
