问题描述
使用Cloudinary及其Carrierwave插件，我可以在视图中编写一个表单，该表单会将图像上传到他们的云并将其绑定到名为 picture 的模型属性中，如下所示：
With Cloudinary and their Carrierwave plugin I can write a form in my view that will upload an image to their cloud and bind it to a model attribute called picture, like so:
<%= form_for(@post) do |post_form| %>
<%= post_form.hidden_field(:picture_cache) %>
<%= post_form.file_field(:picture) %>
<% end %>
这有效。但是，在遵循文档以在Rails中直接上传。他们的示例使用了未绑定到模型的form_tag：
This works. But I can't figure out how to bind the attribute to the model while following their documentation for direct uploads in Rails. Their example uses a form_tag that isn't bound to a model:
<%= form_tag(some_path, :method => :post) do %>
<%= cl_image_upload_tag(:image_id) %>
...
<%= end %>
我正在寻找一些例子，例如<％= post_form。 some_upload_method（：picture）％> 。有人为自己的模型直接上传文件并知道我在找什么吗？
I'm looking for some example that's like <%= post_form.some_upload_method(:picture) %>. Any chance someone else has done this for direct uploads for their models and knows what I'm looking for?
推荐答案
以下语法：
<%= post_form.cl_image_upload(:picture) %>
