Hello!
I''m trying to create a list of user "ads" on my home page in
my app.
But I don''t get it to work. I''m a rails noob so it might be
something
trivial.
I''m currently running into this error:
Couldn''t find User without an ID
My pages controller where to home action is looks like this:
def home
@title = "Startsidan"
@user = User.find(params[:id])
@ads = @user.Ad.paginate(:page => params[:page])
end
And my ad partial looks like this:
<div class="ad body_copy">
<%= image_tag user.avatar.url(:thumb) %>
<span class="content">
<%= link_to user.name, user %>
<%= user.ads.content %>
</span>
</div>
Any help would be appreciated! I hope that my explanation is clear
enough.
Best regards
Anders

Have a look in the log (log/development.log) and it will tell you what the params are. Are you passing the id to the home action? Also you could have a look at the rails guide on debugging to see how to break into your application using ruby-debug and examine the data at that point.

Hello Colin! Thanks for your reply. You are right about where the error is occurring, this line is causing the error, @user User.find(params[:id]). I haven''t passed the id to the home action, where should i do that and how? Sorry for the noobish question but your help would be gold!

Sorry for the noobish question but your help would be gold!That depends what you are trying to do. If you explain that we may be able to help. If you do not know what the params hash is all about then you need to work through some basic tutorials. See the rails guides at http://guides.rubyonrails.org/ if you are using Rails 3 or http://guides.rubyonrails.org/v2.3.8/ if using version 2.3.x. Start with Getting Started obviously, then work through the others.

it the route you set a requirement but you could access the client with a query, something like this link_to <http://user.name/>"Home", root_path(:id=>@user.id) but what this does is add this to the url string ?id=1 and is not what you want since people can still access the original with out ?id=1 gicing user the same message so what you do is create a route like this match ''products/:id'' => ''catalog#view'' <============copied from the routes.rb comments you see here the id is specified that means that it the user access product with no id the message will be no routes matched /products and that is what we want, not an error in the controller is just that there is no page in the site you can access without specifing the id. conclusion is not a good idea to have a root route that requieres an id instead match ''pages/:id'' => ''pages#home'' and root :to => "welcome#index" On Sun, Sep 12, 2010 at 7:48 AM, Anders_P <anders-TlBSdMGKk75YFVMCzM9+FrNAH6kLmebB@public.gmane.org> wrote:> Hi radhames! > > So the problem lies in my routes!?!, do you have any suggestion on how > it should look? > > Thanks! > > // Anders > > > On 12 Sep, 04:48, radhames brito <rbri...-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org> wrote: > > ok there is a problem > > > > @user = User.find(params[:id]) <================= params[:id] is > pulled > > from the url query string > > > > in rails the convention is this > > > > /controller/action/id > > > > in cases there you need to pull one specific record > > > > /controller/action > > > > to pull a collection > > > > @user = User.find(params[:id]) > > > > here you are pulling an specific user but > > > > root :to => ''pages#home'' > > > > there is no id at the end of your so params[:id] has nothing in it > > > > thats why Couldn''t find User without an ID > > > > > > > > On Sat, Sep 11, 2010 at 2:08 PM, Anders_P <and...-TlBSdMGKk75YFVMCzM9+FrNAH6kLmebB@public.gmane.org> > wrote: > > > Thanks for your tips Colin! > > > > > Hi radhames! > > > > > Thanks for your help on my previous topic. > > > > > Here is my routes.rb file: > > > > > resources :users > > > resources :sessions, :only => [:new, :create, :destroy] > > > resources :ads, :only => [:new, :create, :destroy] > > > > > match ''/registrera'', :to => ''users#new'' > > > > > match ''/inloggning'', :to => ''sessions#new'' > > > match ''/utloggning'', :to => ''sessions#destroy'' > > > > > root :to => ''pages#home'' > > > match ''/kontakt'', :to => ''pages#contact'' > > > match ''/om'', :to => ''pages#about'' > > > > > Thanks! > > > > > // Anders > > > > > On 11 Sep, 19:21, radhames brito <rbri...-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org> wrote: > > > > home action seems to be a member restful action and it needs an id to > > > find > > > > the record but you are not declaring that route the right way > > > > show the routes please > > > > > > On Sat, Sep 11, 2010 at 8:25 AM, Colin Law <clan...-gM/Ye1E23mwN+BqQ9rBEUg@public.gmane.org> > > > wrote: > > > > > On 11 September 2010 12:14, Anders_P <and...-TlBSdMGKk75YFVMCzM9+FrNAH6kLmebB@public.gmane.org> > wrote: > > > > > > > Could you not top post please, it is easier to follow the thread if > > > > > comments are inserted into the previous post.

Thanks radhames! I finally got it to work, it turned out that i didn''t need to define @user in my home action, and it was causing the error. Sorry if my description was unclear.
