Hi,
Sorry I didn''t post the right thing. I have two tables category and
book. I have a hidden category_id field in the create book page. So by
right if I submit an empty create book form,
an error message box will show on the top of the page displaying my
errors. But instead, I got the following error. Where did it go wrong.
Please help. Have been stuck for days.
I have also tried to use form_for with render partial but I can''t
submit
my form. It just redirect back to the same page.
Thanks
..........category table........
id integer (primary key)
cat_name varchar
validates_presence_of :name
.........book table.............
id integer(primary key)
name varchar
author varchar
price float
category_id integer(foreign key)
validates_presence_of :name, :author
..........category model............
class Category < ActiveRecord::Base
has_many: books
end
.........book model..............
class Book < ActiveRecord::Base
belongs_to: category
end
.....book.rhtml (view).............
<%= error_messages_for ''book'' %>
<b><u>Create New Book</u></b><p>
<% form_for :book, :action => :save_book, :html => {:id => :book} do
|f|
%>
<%= f.hidden_field :category_id, :value => @category.id %>
<%= button_to "Create", :action => :save_book, :id => :book
%>
<% end %>
.......................................
......_form.rhtml................

..................................
.........error message...............
Called id for nil, which would mistakenly be 4 -- if you really wanted
the id of nil, use object_id

Use submit_tag if you want a submit button.
