Hi there

A very easy and straight forward tutorial, thank you.

Unfortunately I get the following error when I try to input some valid data:

NoMethodError (undefined method 'min_salary_before_type_cast' for #)
app/controller/users_controller.rb:46:in 'create'
…

Not sure what I have missed, can anyone advise?

In Versions above Rails 2.0 , the scaffold does not generate the views from the model . It creates only blank pages.

We need to manually add text fields, textbox etc to it. In windows it often says libmysql.dll not found. You need to copy download http://www.dll-files.com/dllindex/dll-files.shtml... and copy it to C:/Ruby/bin folder in order to solve this error.

Happy Rails Coding

Hey Christian,
you can create a subdirectory just like the one you are doing
ruby script/generate scaffold admin/product title:string (skip the single quotes '')

Excellent tutorial, Michael, but I’ve a question. How can I make a scaffold
inside a subdirectory? For example, I’m trying into
localhost:3000/admin/publisher

How can I make that?

I was trying with script/generate scaffold ‘admin/publisher’ name:string,
but it didn’t work.

Can you help me?

Thanks in advance!
