I have an existing entry in my DB under the “users” table that has a  
column name “pic”. I have a file column field when a new user signs up,  
and it work great. I am now trying to give existing users the ability to  
add or change their “pic”. But, no matter what I do the entry comes up  
blank. Here’s what I have so far:

View:  
\<%= start\_form\_tag ({:action =\> ‘settings\_save’, :id =\> @user.id},  
:multipart =\> true) %\>  
\<%= error\_messages\_for ‘user’ %\>

\<%= file\_column\_field "user", "pic" %\>

\<%= submit\_tag "Change" %\> \<%= end\_form\_tag %\>

controller:  
def settings\_save  
@user = User.find(params[:id])  
@user.update\_attribute(“pic”, params[:pic])  
end

In the log:  
Parameters: {“user”=\>{“pic\_temp”=\>"", “pic”=\>#\<File:/tmp/CGI11901.1\>},  
“commit”=\>“Change”, “action”=\>“settings\_save”, “id”=\>“9”,  
“controller”=\>“account”}

It seems the variable is not being passed correctly. Any ideas?

It appears that in your controller, you want to do:

@user.update\_attribute(“pic”, params[:user][‘pic’]

## Because ‘pic’ is part of the ‘user’ hash. Right?

Steve, you’re my new hero! That was it. I was calling a param that  
didn’t exist. Just in case someone searches for this later you forgot  
the last ‘)’ in the code you gave. The final ine is:

@user.update\_attribute(“pic”, params[:user][‘pic’])

Thanks again.
