Question

这是我的助手功能：

def edit_and_delete_links_for(model)
    model_route_path = model.class.to_s.downcase
    if policy(model).update?
        links = link_to "Edit", self.send("edit_#{model_route_path}_path", model), class: 'btn btn-primary edit-btn'
        if current_user.admin?
            links += link_to "Delete", self.send("#{model_route_path}_path", model), method: :delete, class: "btn btn-danger destroy-btn"
        end
    end
    return links
end

我试图在我的ajax结果中使用它

next.json.rb

{
    "library" : <%= ActiveModel::SerializableResource.new(@library).serializable_hash.to_json.html_safe %>,
    "links": {
        "language" : "<%= language_path(@library.language) %>",
        "framework" : "<%= framework_path(@library.framework) %>"
    },
    "buttons": "<%= edit_and_delete_links_for(@library).to_s %>"
}

出于某种原因，它不会逃脱课程周围的"标记，因为你可以从我看到的铬标记中看到：

{
    "library" : {"id":5,"version":null,"average_rating":"2.0","vote_count":1,"comment_count":0,"description":"Simple ORM for Sinara and Rails","reviews":[{"id":5,"rating":2,"comment":null,"user_name":"first!","updated_at":" 5:04pm on 2017-07-16 (UTC)"}]},
    "links": {
        "language" : "/languages/1",
        "framework" : "/frameworks/2"
    },
    "buttons": "<a class="btn btn-primary edit-btn" href="/libraries/5/edit">Edit</a>"
}

任何想法如何逃避这一点。我试过了json_escape但它没有做任何事情。我认为这个问题是因为它被标记为html_safe，但我还没有找到摆脱它的方法。

在视图中调用escape_javascript方法时，只需使用j（或edit_and_delete_links_for}：

"buttons": "<%= j edit_and_delete_links_for(@library).to_s %>"

或者，作为替代方案，您可以在视图中使用简单引号（'）而不是双引号（"），如下所示：

"buttons": '<%= edit_and_delete_links_for(@library).to_s %>'

escape`link_to`返回通过ajax发送的值
