我在一个简单的博客应用程序中添加了水银,并希望使用最新版本,但我无法将其保存到更新中。这是我的代码:
的Gemfile:
gem 'rails', '3.2.11'
gem "thin", "~> 1.3.1"
gem 'mercury-rails'
gem 'paperclip'
group :development do
gem 'taps'
gem "nifty-generators"
gem 'sqlite3'
end
gem 'jquery-rails'
blogs_controller.rb:
def update
@blog = Blog.find(params[:id])
if @blog.update_attributes(params[:blog])
redirect_to @blog
else
render 'edit'
end
end
def mercury_update
blog = Blog.find(params[:id])
blog.content = params[:content][:blogContent][:value]
blog.save!
render text: ""
end
blog.rb:
class Blog < ActiveRecord::Base
attr_accessible :title, :content, :author
end
routes.rb中:
Mercury::Engine.routes
mount Mercury::Engine => '/'
root :to => "pages#home"
namespace :mercury do
resources :images
end
resources :blogs do
member { post :mercury_update }
end
mercury.html.erb
<body>
<script type="text/javascript">
// Set to the url that you want to save any given page to, leave null for default handling.
var saveUrl = null;
// Instantiate the PageEditor
new Mercury.PageEditor(saveUrl, {
saveStyle: 'form', // 'form', or 'json' (default json)
saveMethod: null, // 'PUT', or 'POST', (create, vs. update -- default PUT)
visible: true // boolean - if the interface should start visible or not
});
</script>
</body>
博客/ show.html.erb:
<div id="blogFull" class="rounded-corners-mild">
<div id="blogTitle">
<h1 style="font-size:150%; text-align:center; " class="mercury-region" ><%= @blog.title%></h1>
</div>
<div data-mercury="full" id="blogContent" class="mercury-region">
<%= raw @blog.content %>
</div><br />
<%= link_to "mercury", "/editor" + "/blogs" + "/#{@blog.id}", :class => 'bestButton',
id: "edit_link", data: {save_url: mercury_update_blog_path(@blog)} %>
添加到:mercury.js:
jQuery(window).on('mercury:ready', function() {
var saveUrl = $("#edit_link").data("save-url");
Mercury.saveUrl = saveUrl;
});
Mercury.on('saved', function() {
window.location.href = window.location.href.replace(/\/editor\//i, '/');
});
我也试过这个:对mercury.js:
onload: function() {
//Mercury.PageEditor.prototype.iframeSrc = function(url) { return '/testing'; }
Mercury.on('ready', function() {
var link = $('#mercury_iframe').contents().find('#edit_link');
Mercury.saveUrl = link.data('save-url');
link.hide();
});
Mercury.on('saved', function() {
window.location.href = window.location.href.replace(/\/editor\//i, '/');
});
}
都没有奏效。两个人都让我去编辑并允许我编辑。我还没能保存任何更改。谢谢。

尝试保存时是否收到错误消息?它说什么?如果它说它无法保存但URL正确则要检查日志文件。
我在设置正确的saveUrl时遇到问题,并将以下内容添加到mercury.js中为我修复了它;
onload: function() {
Mercury.on('ready', function() {
var link = $('#mercury_iframe').contents().find('#edit_link');
console.log("mercury ready ready", link);
mercuryInstance.saveUrl = link.data('save-url');
link.hide();
});
Mercury.on('saved', function() {
window.location.href = window.location.href.replace(/\/editor\//i, '/');
});
}
在this thread on RailsCasts中找到它。
编辑:
我在你的代码中注意到其他内容。您为POST操作创建了一个路由。在mercury.html.erb中,默认情况下saveMethod设置为“PUT”。将saveMethod更改为“POST”。

对我来说,我遇到了“mercuryInstance”无法解决上述问题。我确实使用了这个添加到mercury.js结尾的javascript:
jQuery(window).on('mercury:ready', function() {
var link = $('#edit_link');
Mercury.saveUrl =link.attr('data-save-url');
link.hide();
});
