Comment on Building a todo list with Rails 3 – Part Two by Sonya

Hi Robin! This is my first attempt at any rails code EVER! I’ve been following along quite smoothly until I hit the same error message as Ryan and Johnny.

….. No route matches {:controller=>”tasks”, :action=>”complete”, :list_id=>2, :id=>nil}

I have rails v 3.1.3 Johnny posted a fix which I attempted to implement but it does not seem to work for me – the error message remains exactly the same.

Could Johnny perhaps have made an error in his post? His fix for the ListController Show method doesn’t seem to change your code in any way.

QUOTE:

i changed my ListController show method from:

def show
@list = List.find(params[:id])
@task = @list.tasks.new
end

to :

def show
@list = List.find(params[:id])
@task = @list.tasks.new
end

Those two bits seem to be identical?

Please help – I was so enjoying the tutorial and would love to complete it before my holiday is over

Thanks a million!

I try to create a autocomplete that folow the input cursor. Have somebody something styled like that?

Hi Johnny! Yes, does look like the new task is being appended to the list but because it’s not been created, it doesn’t have an id and that’s why the error is thrown. It may have been a change in Rails that causes initialised but not created objects to be added to a collection.

I was able to get the new task item on the show list page to work correctly for me:

i changed my ListController show method from:

def show
@list = List.find(params[:id])
@task = @list.tasks.new
end

to :

def show
@list = List.find(params[:id])
@task = @list.tasks.new
end

and my list/show page form from

form_for [@list, @task] do |form|

to :

form_for [@list, @list.tasks.new] do |form|

and boom! like magic. Any insights to why that might be happening?

I got the same error Ryan did. I think the problem is in the controller? (Disclosure: not a rails dev)

It seems the task created by:

def show
@list = List.find(params[:id])
@task = @list.tasks.new
end

is appended to the @list.tasks, and shows up as an extra list item task in the lists/show view?

I’m on OSX Snow Leopard, Ruby 1.8.7, Rails 3.1.1 and followed the tutorial to a “t” (character by character, watched everything 3 times) could it be a version/gem idiosyncrasy somewhere?

%= button_to “Complete”, complete_task_path(@list.id,task.id) % – brackets are by % signs, not showing up though

Is my button code if that helps, it looks like it is all there to me, really confusing me!

It appears that the id for the task is not being passed in. Your code should be:

complete_task_path(@list.id,task.id)

Are you passing the task.id into the link? Note there is no @ symbol before it in this case.

Great tutorial! Really learning a lot! Just running into one thing -

in routes.rb I have:

resources :lists do
resources :tasks
end

match ‘lists/:list_id/tasks/:id/complete’ => ‘tasks#complete’, :as => :complete_task

root :to=> “lists#index”

But I get this error when trying to use the app:

No route matches {:list_id=>1, :controller=>”tasks”, :action=>”complete”, :id=>nil}

What did I screw up on?

Thanks
