How do I redirect back to a page I'm currently on? - leisureness30203 - 07-19-2023
In my users photo album page they see photos they have uploaded and each photo has a 'make default' link on it.
When the user clicks `make default`, then the id of the photo is stored in the `photo_id` column of my profiles table.
The issue is redirecting them back to:
localhost:3000/settings/photo_gallery/:id
Is there a way I can redirect back to the photo album using the id of the photo that has just been set as the default? Can Rails find what album I want to redirect to just by looking at the id of a photo, as a photo belongs to a photo album, and a photo album has many photos?
I have the following tables in my database:
* User(s): has one profile, has many PhotoAlbums
* Profile(s): belongs to user
* PhotoAlbum(s): belongs to user, has many photos
* Photo(s): belongs to PhotoAlbum
Controller action:
def set_default_profile_photo
photo = Profile.find_by_user_id(current_user.id)
photo.photo_id = params[:photo_id]
photo.save
redirect_to "**HERE IS WHERE I'D LIKE TO REDIRECT TO THE PHOTOALBUM THE PHOTO IS IN**"
flash[:success] = "Default photo set!"
end

In Rails 5 it was introduced the function:
redirect_back(fallback_location: root_path)
It does redirect back whenever the `HTTP_REFERER` is known. Otherwise it redirects to the `fallback_location`.
The `redirect_to :back` is deprecated and will be removed from Rails 5.1.

This is what you want:
redirect_to request.referrer

`redirect_to :back` worked for me but I want to see if this was the right choice

If you came from the photo_album page, you should be able to do:
redirect_to :back
Otherwise, you should be able to do a named route like:
redirect_to photo_album_path(photo.album_id) # or whatever the association key is
BTW, why do you have photo_albums mapping to photo_galleries? It's a lot less confusing if you named your resources and routes in a similiar manner. ie: if you wanted your route endpoints to use /photo_galleries you should name your resource PhotoGallery.

In one project we used the session for temporary storage, because `redirect_to :back` did not work for us.
We had an `def new` where we set `session[:return_to] = request.referer`
in the `def create` we added `redirect_to session[:return_to]`.
I do not know anymore, why we could not use `redirect_to :back`
