Hi friends,

I have two table…

1. 

* * *

```
       users

```

* * *

## id(pri) | user\_name | email|

1. 

* * *

```
      posts

```

* * *

## post\_id | user\_id(foreign\_key)| title | body

Relations is A user has many posts.

I created a form for post.

with

title:-----------------------------------

## body:------------------------------------

* * *

* * *

submit\_button.

in controller I wrote logic for submit this form so that,  
all the title & body gets added into database.

But, the foreign key is not being added.

How am i suppose to do?

Well in an ideal world you’ve have something containing the user that  
is creating the post (eg current\_user) and you would have created your  
associations between these two classes. You could then do  
current\_user.posts.create :title =\> …

You could start by looking at the rails guide about action controller  
( [Action Controller Overview — Ruby on Rails Guides](http://guides.rubyonrails.org/action_controller_overview.html#session)  
)  
There are a number of plugins/gems for handling authentication such as  
authlogic & restful\_authentication
