I created model objects of from generating a scaffold, but now I want to instead of linking to
/:controller/:id (/objectname/1) to /:controller/:title (/objectname/new_blog_post). How do I do this so that links will correct link to the title and not id?
I want to go from:
/:controller/:id
to
/:controller/:name
You will need to change a few things:
You'll have to pass the title attribute to any paths/urls when you do stuff like link_to e.g.
post_path(@post)
will become
post_path(@post.title)
You'll also have to update your finds to look for posts by title, as opposed to id e.g.
@post = Post.find(params[:id])
will become
@post = Post.find_by_title(params[:title])
That should get you started :). You'll obviously want to slug the title and validate the uniqueness of the title as well.
EDIT: After reading Robert Elwell's answer, maybe I misunderstood the question. Do you already have a route like you described for a specific object, or are you doing this with the 'basic' routes? If the latter, you're much better off writing a custom route like Robert suggests, and then doing some of the stuff I suggested.
Use to param
class User < ActiveRecord::Base
def to_param
name.blank? ? id : name
end
end
Or look into a plugin, acts_as_sluggable and friendly_id are ones I know of.
EDIT: Oh yes and as mentioned make sure whatever you use is unique.
EDIT:
it would work like:
class UsersController < ActionController::Base
def index
@users = User.all
end
end
In view:
<% @users.each do |user| %>
<%= link_to user.name, user_path(@user.id) %>
<% end %>
And if the that users name is John then it will render /users/John after you click that link
