I have a resource named Image in a Rails app. How can I access the dynamically generated path helpers?

Question

The important one in question is MODELNAME_path , which in this case would be image_path , but this seems to clash with the existing method in ActionView::Helpers::AssetTagHelper .

I'm currently calling image_path(@image) in an RSpec view spec file, and it's taking me, reasonably, to the method in AssetTagHelper and raising an exception, since I'm trying to pass it an object when it ordinarily takes a string.

My first instict was to try url_for , but this, most curiously (and I can't figure out the reason for this one; feel free to enlighten me), eventually just delegates the work back to AssetTagHelper.image_tag . Weird.

So the bottom line question is how I should go about specifically calling the dynamically defined image_tag , and in general how to differentiate the two.

This is the last time I ever name a resource Image.

Answer 1

您是否尝试过polymorphic_path（@image）而不是image_path（@image）？

Answer 2

实际上，Rails建议您使用path_to_image解决此确切问题。
