We have the table post (id,title, text, date)
and category (id, name)

Then the goal is to create a table with name, say post_category linking id in post and id in category.

What do you have to say about the above?

Thanks.

Please help!

Great tutorial, I'm just getting into Ruby on Rails and really wanted to get my own blog platform up and running asap, so this is helping loads!

One thing I noticed, when you modify the category selection box to become an option field rather than a text box I believe you can do it with one line as follows:

<%= f.collection_select :category_id, @cat, :id, :category_name %>

That uses the @cat variable from the controller and handles the looping for you, I picked it up from the apple tutorials on RoR and just thought it was worth mentioning as it is a little more lightweight and elegant solution

Moving on!

Anyway why is grant being an ass? If ya gunna critize it, ya gotta constructify it, brother! How should this article be better? Can you write an article for us that does this but better? Like “The best freaking article on creating categories in Ruby on Rails!!”

I got a question though, how do I know the relationship has been formed? How do I know the project knows Posts belongs to Categories, and Categories has many Posts?
