Rails页面中的多个视图

Question

I have a very high level question that I cant find an answer to that makes sense to me. I understand it''sa terribly broad question but I'm only after some pointers in where to look for answers, not instructions on how to build my site.

So... If I want to render two different types of content in a single page using rails, how would I go about doing this? And how would I format the url? Say I create a gallery model and controller which has information about the gallery and perhaps a description, then I create a gallery-entry controller and model that belongs to the gallery which has an image and image name. If I want to create a url something like www.siteURL/galleryName/GalleryEntry that renders both the gallery info and description and all the associated gallery-entries but also a larger version of the gallery-entry that is named in the url where would i start and how would i structure this? How would i go about creating a url that has multiple attributes and how would i access them in the controller/view?

Thanks - and sorry for the vague question

There's several ways to go about it.

Your URL looks like a "vanity" URL that would exist in addition a normal RESTful route ( galleries/:gallery_id/entries/:entry_id ). The difference is that you don't want to show just the gallery entry.

If you want to specifically differentiate between different views of the same resource there are a number of ways it could be done, the two I'd consider first are adding another action, or adding a disambiguating query parameter. In this case, it's a hybrid, so I'd probably create a custom match and controller method.

The mapping might look like:

match ':galleryName/:entryName' => 'gallery#highlight_entry' # Or whatever

The action would be (more or less):

def highlight_entry
    @gallery = Gallery.find_by_name(...)
    @entries = @gallery.entries
    @highlighted_entry = # pull from @entries, or retrieve
    # Also, filter entries/etc. so the highlighted one doesn't show up
    # etc
end
