Tutorials Point - Simply Easy Learning

Dear Friends,

This is just for your information that I have started preparing a tutorial on Ruby on Rails 2.1 and it will be uploaded before end of June 2008.

Hope you will like this tutorial as well.

Thanks

Hello,

Have I missed something really obvious here ?
The 'Database Setup' page just creates an empty database - then the tutorial moves on to generating the model, even though the tables don't exist yet ?

Should we create the tables in SQL first - if so, can you provide the SQL so it is just a cut and paste job.

Thanks,
Richard.

Hello,
I have been following this tutorial, but ran into a problem. In:
http://www.tutorialspoint.com/ruby-on-r ... -views.htm
I get to the point where I created the new method, but once I navigate to http://localhost:3000/book/new, I end up with this error:

NoMethodError in Book#new
Showing app/views/book/new.html.erb where line #4 raised:
undefined method `title' for #<Book id: nil, created_at: nil, updated_at: nil>

Extracted source (around line #4):
1: <h1>Add new book</h1>
2: <% form_tag :action => 'create' do %>
3: <p><label for="book_title">Title</label>:
4: <%= text_field 'book', 'title' %></p>
5: <p><label for="book_price">Price</label>:
6: <%= text_field 'book', 'price' %></p>
7: <p><label for="book_subject">Subject</label>:

Can someone help me out. This is my first RoR tutorial and I'm already stuck


Thanks!

Hi,

I would suggest you to follow my tutorial a to z. I have tested all the examples very well before uploading them on the site.

Thanks

I have been following it A to Z multiple times now. I still get an error associated with the "new" view, specifically the text_field or collection_select methods. I get a "No Method Error" that reads:

Showing app/views/book/new.html.erb where line #4 raised:
undefined method `title' for #<Book id: nil, created_at: nil, updated_at: nil>


I believe that the tutorial works, I'm just looking for help with what might be wrong with my setup if I make it all the way to this point and repeatedly run into this problem. Thanks.

Hi, I have the same problem:

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: <h1>Add new book</h1>
2: <%= form_tag :action => 'create' %>

5: <p><label for="book_price">Price</label>:
6: <%= text_field 'book', 'price' %></p>
7: <p><label for="book_subject">Subject</label>:

annoying isn't it?! MIGHT IT BE A VERSION PROBLEM???

I am glad that I was of help. I had been occupied by some extra stuff for last 2 weeks and hence I was not able to post part 2. But I will do it soon, so stay tuned.
I have actually been trying to learn rails 1.x with my “newâ€

I had this problem but then I found I needed to modify the migrations files in the db/migrate folder as it discusses on this page: http://www.tutorialspoint.com/ruby-on-r ... ations.htm

TimSC

mistake in example http://www.tutorialspoint.com/ruby-on-r ... emails.htm
def index
render :file => 'app\views\emailer\index.htm.erb'
end

should be

def index
render :file => 'app\views\emailer\index.html.erb'
end

Please use blackslash before opening square bracket becuase this is reserved to specifiy multiple search options....

So try the following and it won't give warning..
