WickedPDF缺少布局 [英] WickedPDF missing layout
问题描述
我有一个这样的控制器：
I have a controller like this:
def show
@professor = Professor.find(params[:id])
respond_to do |format|
format.html
format.pdf do
render :pdf => "file_name"
end
end
end
如下所示：
And a simple view like this:
<p>Professor: <%= @professor.first_name %></p>
<p>Email: <%= @professor.email if @professor.email %></p>
我也有一个布局'application.html.erb';
I also have a layout 'application.html.erb';
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title><%= content_for?(:title) ? yield(:title) : "Myapp" %></title>
<meta name="description" content="">
<meta name="author" content="">
<%= stylesheet_link_tag "application", :media => "all" %>
<%= javascript_include_tag "application" %>
<%= csrf_meta_tags %>
<%= yield(:head) %>
</head>
<body>
<header class="navbar navbar-fixed-top">
<nav class="navbar-inner">
<div class="container">
<%= render 'layouts/navigation' %>
</div>
</nav>
</header>
<div id="main" role="main">
<div class="container">
<div class="content">
<div class="row">
<div class="span12">
<%= render 'layouts/messages' %>
<%= yield %>
</div>
</div>
<footer>
</footer>
</div>
</div> <!--! end of .container -->
</div>
执行以下命令时：
When I do the following command:
bundle exec wkhtmltopdf 'http://local.myapp.com:3000/professors/2' - > test.pdf
我得到一份包含所有样式和布局的pdf。
I get a pdf with all the styles and layout properly.
然而，当我去 http://local.myapp.com:3000/professors/2.pdf 时，我得到一个错误：
However, when I go to http://local.myapp.com:3000/professors/2.pdf I get an error saying:
Missing template professors/show with {:locale=>[:en], :formats=>[:pdf], :handlers=>[:erb, :builder, :coffee]}
我改变了我的控制器＃show action就像这样：
So, then I changed my controller#show action to be like this:
def show
@professor = Professor.find(params[:id])
respond_to do |format|
format.html
format.pdf do
render :pdf => "file_name",
:template => 'professors/show.html.erb'
end
end
end
这有助于我呈现视图，但不幸的是它不呈现样式和布局。我的问题是：
That helps me to render the view, but unfortunatelly it doesn't render the styles and the layout. My questions are:
- 为什么需要指定模板？
- 为什么布局不在PDF中呈现？
推荐答案
您需要将您的视图重命名为show.pdf .html.erb或创建一个新的show.pdf.erb。
You need to rename your view to show.pdf.html.erb or create a new show.pdf.erb.
文件名中的.pdf让处理程序知道它可以使用它。
The .pdf in the filename lets the handler know it can use it.
另外，您可能需要使用wicked_pdf_stylesheet_link_tag助手来显示样式。如果你想有一个双重用途的视图，那么可能需要这样的东西：
Also, you probably need to use the wicked_pdf_stylesheet_link_tag helper to get your styles to show up. If you want to have a dual-purpose view, then something like this may be necessary:
<% if params[:format] && params[:format] == 'pdf' %>
<%= wicked_pdf_stylesheet_link_tag 'application' %>
<% else %>
<%= stylesheet_link_tag 'application' %>
<% end %>
