【问题描述】:
在我的 Ruby on Rails 应用程序中,我通过 Rails 的 UJS(不显眼的 JavaScript)使用 Ajax。
这是完美的工作:当用户在交易页面上,然后当他点击某个文本链接时,会进行 Ajax 调用并加载带有远程内容的模式。
但我想为用户提供一种方式,让他们直接到达已经打开模式的页面,而无需他加载交易页面然后点击文本链接。 例如,用户可能会收到一封电子邮件并单击它,他会立即到达已打开模式的交易页面。
但它不起作用,当我采取模式的路线(见下面的代码)并在浏览器中输入 http://myapp.com/deals/:id/deal_opportunities_modal 时,它会给出以下错误:
在 29 毫秒内完成 406 不可接受
ActionController::UnknownFormat - ActionController::UnknownFormat:
actionpack (4.2.0) lib/action_controller/metal/mime_responds.rb:218:in respond_to'
app/controllers/deals_controller.rb:70:inshow_opportunities'
这是我的文件:
controller/deals_controller.rb
# used so that old urls created for deals redirects to the new ones created
# indeed with friendly_id, the url is taken from the title :/deals/title
# but if we edit the deal title to deal/title2, the old url was still working
# we need to redirect the old url
# source - github.com/norman/friendly_id/issues/385
before_filter :find_deal,
:only => [ :showcase ]
before_filter :ensure_canonical_deal_path!,
:only => [ :showcase ]
def showcase
@deal = Deal.friendly.find(params[:id])
respond_to do |format|
format.html # showcase.html.erb
format.json { render json: @deal }
end
end
def show_opportunities
@deal = Deal.friendly.find(params[:id])
@opportunity = Opportunity.where('deal_id = ? AND deal_type = ?',
@deal.id, "high tech").first
respond_to do |format|
format.js
end
end
protected
def find_deal
@deal = Deal.friendly.find params[:id]
end
def ensure_canonical_deal_path!
if request.path != deal_page_path(@deal)
redirect_to deal_page_path(@deal, :format => params[:format]), :status => :moved_permanently
return false
end
end
app/views/deals/showcase.html.erb
<% if @deal.present? %>
this is the beginning
<%= render 'deals/deal_info_zone' %>
this is the end
<% end %>
views/deals/_deal_info_zone.html.erb
<div id="zoneA">
<div style="color:red;padding-top: 150px;">
<%= link_to "view infos of the latest Opportunity", deal_opportunities_modal_path, remote: true %>
</div>
</div>
views/deals/deal_opportunities_modal.js.erb
这里是通过 Ajax 触发的模式:views/deals/opportunity_modal。请注意我在这里如何尝试通过 Deal 但没有成功,因此该行
$('body').append('<%= j render partial: "deals/deal_opportunities_modal" %>');
$('#myModal').modal('show');
/app/views/deals/_deal_opportunities_modal.html.erb
现在是模态视图/内容:
<div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-body">
this the the latest opportunity: <%= @opportunity.name %> <br/>
</div>
</div>
</div>
</div>
routes.rb
match '/deals/:id', # this is the Deal page
to: 'deals#showcase',
via: 'get',
as: :deal_page
match '/deals/:id/opportunity_modal',
to: 'deals#show_opportunities',
via: 'get',
as: :deal_opportunities_modal
如何实现这一点,即如何创建一种路由/URL,当用户使用该路由/URL 时,他会在模式“show_opportunites”已经打开的情况下到达交易页面。
我听说过 js-routes,但它似乎对其他用途很有用(即在 javascript 文件中使用 Rails 路由)。
如果我让用户使用已经打开的模态访问页面,还会存在安全问题吗?
