在我的Rails应用中,用户可以使用文件夹创建新的博客文章。我想在用户创建新帖子时刷新包含所有文件夹帖子的部分。我试图在文件夹控制器中创建一个动作,再次调用部分并替换它,但我得到一个CanCan :: AccessDenied 500错误。
在我的index.html.erb中,这是我的文件夹show partial:
的链接<%= link_to folder_path(folder), remote: true %>
这是加载到视图中的部分:
<div id="panel-container">
<div id="entry-container" class="entry-window">
<div id="meta-bar" class="top">
<span id="location-span" style="position:relative; float:left;">In <%= @folder.title %></span>
<div id="entry-meta" class="meta-info">
<i class="icon-ok icons" id="save-entry"></i>
<i class="icon-remove icons" id="close" style="margin-left:10px"></i>
</div>
</div>
<div id="entry-create-partial" class="contain-entry">
<div id="title-create-partial" class="title-partial" name="title" contenteditable="true" data-placeholder='Title it' style="color:black"></div>
<div id="meta-popup"><button type="button" class="btn" id="nested-button">Create Nested Entry</button></div>
<div id="content-create-partial" class="content-partial" name="content" contenteditable="true" data-placeholder='Write anything' style="color:gray"></div>
</div>
</div>
<div id="container-edit" class="entry-window">
<span id="location-span" style="position:relative; float:left;">In <%= @folder.title %></span>
<div id="entry-meta" class="meta-info">
<button type="button" id="save-edit" class="btn">Save</button>
<button type="button" class="btn" id="close-edit"><i class="icon-remove" id="entry-cancel-x close-edit"></i>Cancel</button>
</div>
<div id="entry-edit-partial" class="contain-entry">
<div id="title-edit-partial" class="title-partial" name="title" contenteditable="true" style="color:black"></div>
<div id="content-edit-partial" class="content-partial" name="content" contenteditable="true" style="color:gray"></div>
</div>
</div>
<div id="right-panel">
<div id="top" class="top">
<h3><%= @folder.title %></h3>
<ul id="inner-list">
<button class="btn" id="journal-create-button">New Journal</button>
<div id="create-journal-drop">
<form action="/folders" method="post">
<%= hidden_field_tag :user_id, current_user.id %>
<%= hidden_field_tag :parent_id, @folder.id %>
<h3 id="journal-create-partial">New Sub-Journal</h3>
<input type="text" id="titleinput" name="title" placeholder="Title it"></input>
<button type="submit" class="md-close folder-create" id="folder-create">Create</button>
</form>
</div>
<button class="btn" id="entry-button">New Entry</button>
<button type="button" id="delete-button" class="btn"><i class="icon-remove"></i></button>
</ul>
</div>
<% if @folder.submissions.count > 0 %>
<svg id="submission-circles">
<circle></circle>
<circle></circle>
<circle></circle>
<circle></circle>
</svg>
<% else %>
<h2>It's quiet in here. Create a journal entry or sub-journal to get started!</h2>
<% end %>
</div>
</div>
正如我所说,我想重新加载整个部分,以便反映新数据而无需用户执行整页刷新。
我在文件夹控制器中创建了一个新操作,如下所示:
def ajax_load_events
respond_to do |format|
format.js
format.html
end
end
Ajax_load_events.js:
$("#panel-container").replace_html('<%= escape_javascript(render(:partial => "contents", :locals => {:folder => @folder})).html_safe %>');
最后,我的AJAX电话:
$("#save-entry").click(function(){
$.ajax({
type: "POST",
url: "/submissions",
dataType: "json",
data: {title: $("#title-create-partial").text(), content: $("#content-create-partial").text(), folder_id: <%= @folder.id %>},
complete: function(){
$.get("/ajax_load_events/", {folder: <%= @folder.id %>}, null, "script");
}
});
})
这是我的routes.rb中的路线:
get "/ajax_load_events(.:format)" => "folders#ajax_load_events"
答案 0 :(得分:0)
您可能无法正确定义用户能力。尝试将以下行之一添加到能力文件的底部:
can :ajax_load_events, Folder
允许用户执行特定的控制器操作。
或者:
can :manage, Folder
允许用户对资源执行所有类型的操作(不仅仅是CRUD)。
