[英]Ruby on Rails routes prefixes not pre-processing in .erb.js file
I'm using Rails 4. I have the following file: 我正在使用Rails4。我有以下文件:
// apps/assets/javascripts/products.js.erb
var getColoursAndMaterialsData = function(onSuccess)
{
var fd = formdata();
$.post( '<%= data_products_path(:format => :json) %>', fd )
.done(function(data)
{
onSuccess(data);
});
};
When products.js.erb is included in a .html.erb file I get the error: 当products.js.erb包含在.html.erb文件中时,出现错误:
undefined method `data_products_path'
clearly routes prefix 'data_products_path' isn't being pre-processed. 显然,路由前缀“ data_products_path”没有经过预处理。 I was under the impression that giving the products.js the .erb extension would coax the pre-processor.
我给人的印象是给product.js提供.erb扩展名可以哄骗预处理器。
The same exact same code works when between the <script type="text/javascript"></script>
tags in the .html.erb file. 在.html.erb文件中的
<script type="text/javascript"></script>
标记之间时,相同的代码完全相同。 The relevant part of my routes.rb looks like this: 我的routes.rb的相关部分如下所示:
resources :products do
collection do
post 'data'
end
end
Is there something else I need to do? 还有什么我需要做的吗?
I dont think it will work just by adding .erb
extension. 我认为仅通过添加
.erb
扩展名就不会起作用。 why not do a simple jQuery ajax post request... 为什么不做一个简单的jQuery ajax发布请求...
use dataType: "json"
to make sure you get json response and instead of using url helpers just specify the url. 使用
dataType: "json"
来确保获得json响应,而不是使用url helper而是指定url。
