start\_form\_tag has been deprecated and subsequently removed. use  
form\_tag instead:

\<% form\_tag :action =\> :foo, … do %\>  
form elements here  
\<% end\>

While doing a tutorial on tutorialpoint, I had the same problem! I made  
the change, but I get another error :

NoMethodError in Book#new

Showing app/views/book/new.rhtml where line #4 raised:

undefined method `title’ for #\<Book id: nil, created\_at: nil,  
updated\_at: nil\>  
Extracted source (around line #4):

1:

# Add new book
  
2: \<%= form\_tag :action =\> ‘create’ %\>  
3: 

Title:  
4: \<%= text\_field ‘book’, ‘title’ %\>

  
5: 

Price:  
6: \<%= text\_field ‘book’, ‘price’ %\>

  
7: 

Subject:

here is the new.rhtml file:

# Add new book
\<%= form\_tag :action =\> 'create' %\>

Title: \<%= text\_field 'book', 'title' %\>

Price: \<%= text\_field 'book', 'price' %\>

Subject: \<%= collection\_select(:book,:subject\_id,@subjects,:id,:name) %\>

Description  
\<%= text\_area 'book', 'description' %\>

\<%= submit\_tag "Create" %\> \<%= end\_form\_tag %\> \<%= link\_to 'Back', {:action =\> 'list'} %\>

thanx indeed for your help!
