I am trying to replicate the “demo/tutorial” at

[http://d-haven.org/modules/news/article.php?storyid=28](http://d-haven.org/modules/news/article.php?storyid=28)

I have ran the generator and followed the instructions in the  
accompanying generator readme\_login file.

I have setup up a user database of the form

create\_table :users do |t|  
t.column :login, :string, :limit =\> 40  
t.column :password, :string, :limit =\> 40  
t.column :email, :string, :limit =\> 40  
t.column :name, :string, :limit =\> 40

and from there followed the procedures listed at the site noted above  
thru the end of Step 2 including creating another table (articles table  
referred to in demo) with a user\_id :interger column.

After creating a user I attempt to create and save an article  
instance/record which fails at the

validates\_presence\_of :user

Can you see anything in the “demo/tutorial” code which is out of place  
or have I missed some step required to get the session :user properly  
assigned to the @article instance?

Thanks,  
Bernie

Do you have a ‘user’ field on your Articles table?

I only skimmed the start of the post, but my first thought is that the  
articles table should have a ‘user\_id’ field, not a ‘user’ field, to  
link Articles to Users through the has\_many/belongs\_to associations, and  
then the line should be:

validates\_presence\_of :user\_id

The field in the articles table is user\_id.

Also in the tutorial articles\_controller there are references to  
@article.user and @session[:user]. Should these not be .user\_id as  
well? (pardon my noobiness)

I have a user\_id field in the Articles table.

Have a look to the session[:user] and so on, I think Login-generator  
puts the values with ‘’ (e.g. session[‘user’]), and you articles or some  
other stuff may be asking for session[:user]
