由 孤人 提交于 2020-01-14 15:27:32
问题 I've created a method in my app that saves my layout as an image and presents it in the gallery. I'm trying to open it but I'm having a hard time with all the tutorials and different approaches...

由 懵懂的女人 提交于 2020-01-03 10:22:04
问题 I'm having some problems with Rails 3 and HAML in my application: for some reason Rails appears not to be loading the handler for dealing with haml files. Every action gives an error message similar to this one: Template is missing Missing template contact_search/index with {:formats=>[:html], :handlers=>[:rjs, :rhtml, :rxml, :builder, :erb], :locale=>[:en, :en]} in view paths "/var/www/osphonebook/app/views", "/var/www/osphonebook/vendor/bundle/ruby/1.8/gems/devise-1.3.4/app/views" Look at

问题 I'm trying to print user name into a mail template which has been created via rails g mailboxer:views. Whenever I try to call the method, raises an "method or variable current_user not found", although public methods as User. id do prints. Here's the view <!DOCTYPE html> <html> <head> <meta content="text/html; charset=UTF-8" http-equiv="Content-Type" /> </head> <body> <h1>You have a new reply from <%= current_user.name %>: <%= @subject %></h1> <blockquote> <p> <%= raw @message.body %> </p> <

Creating a Blank Rails 3.1 Templating Handler

由 孤街浪徒 提交于 2019-12-24 01:01:42
问题 What I want to do is make it just output the view itself, and ignore what Rails would normally think is embedded Ruby within the HTML. For example: <div class="current"> <div class="question"> <h3 id="homework_name"><%= homework.name %><h3 id="due">Due <%= homework.due %></h3></h3> <h2 class="title">The Question:</h2> <p id="question_contents"class="contents"><%= current_question.contents</p> </div> <div class="answer"> <h2 class="title">Your Answer:</h2> <textarea class="contents" id=

How to trim leading whitespace with `<%=` in ERB templates in Rails that end up in `pre` elements?

由 自古美人都是妖i 提交于 2019-12-23 18:34:24

It could be a minor defect in Erubi template engine as well, the one being used by Rails for ERB templates.) I want to render / syntax-highlight code in a view, and my ERB view template contains: <p> <strong>Code:</strong> <pre class="highlight github"> <%= highlight(@code.code, @code.language) %> </pre> </p> The result is

How to open a file in Android via an Intent

由 前提是你 提交于 2019-12-23 06:56:09
问题 how can I open a file that has been previously stored in the "privat" filesystem? The file is being downloaded by a webservice and should be stored on local fs. I got a "strange" error when trying to open the file via an Intent (Action_View). Although the file is present in the filesystem (saw the file in the file explorer in emulator/eclipse) it won't be shown in the calling galery activity that is launched. Instead of the picture the galery shows a black screen with not content in there
