19,319 PointsWhy can't I use redirect_to method to redirect to an object?
I use this code in my pages controller:
def create
params_page = params.require(:page).permit(:title, :body, :slug)
@page = Page.new(params_page)
@page.save
redirect_to @page
end
However when I clicked submit button, it said:
NoMethodError in PagesController#create
undefined method `page_url' for #<PagesController:0x9c9d0b0>
Extracted source (around line #18):
16 @page = Page.new(params_page)
17 @page.save
18 redirect_to @page
19 end
20
21 end
What is the problem? Thanks.

Treehouse Teacherredirect_to @page
requires that a page_url
method be defined that takes a Page
object as an argument.
There are a couple different ways to define that method. One is to ensure your routes.rb
file has a line like this:
get '/pages/:id', to: 'pages#show', as: 'page'
The as: 'page'
part is what names the route and generates the page_url
method.
