Find(params[:id]) question

#1

Admin Controller -

def show
@wizard = Wizard.find(params[:id])
end

View -

<%= link_to 'Show', :action => 'show', :id => wizard %>

URL -

http://localhost:3000/admin/show/1

I want user_name (one of the columns in the database) instead of the id
to show
For example:
http://localhost:3000/admin/show/‘user_name’

Any ideas?

#2

def show
@wizard = Wizard.find_by_user_name(params[:id])
end

That brings back:

NoMethodError in Admin#show

Showing app/views/admin/show.rhtml where line #1 raised:

You have a nil object when you didn’t expect it!
The error occured while evaluating nil.user_name

Maybe it’s more sane to use params[:username] since whe are dealing with
a
username?
Don’t get scared by the ugly admin/show/?username=john URL, just edit
config/routes.rb to handle the URL mapping stuff.

You need to remove the single quotes in the URL.
