Insert data into a database without user input

Rails
1

Hello there,
I am new around here and have been looking over the internet for a
solution but can’t find one. I am fair new to rails but have a decent
understanding of it to get by and a few years experience behind me.
My problem is that I try to insert data in a database and it does not
come up. The information the user types is inserted however I wish to
insert the ID and other stuff the user can not change.
This is what I have so far:

The controller:

def create
@postform = new(params[:postform])
@post = Post.new(:title => @postform.title, :body => @postform.body,
:user_id => session[:user_id]).save
respond_to do |format|
if @post.save
format.html { redirect_to(@post, :notice => ‘Post was
successfully created.’) }
format.xml { render :xml => @post, :status => :created,
:location => @post }
else
format.html { render :action => “new” }
format.xml { render :xml => @post.errors, :status =>
:unprocessable_entity }
end
end
end

View:

New post

<%= form_tag :action=>‘create’ %>
Title: <%= text_field(“postform”, “title”,:size=>“20” ) %>


Body: <%= text_area(“postform”, “body”,:size=>“20” ) %>


<%= label(“postform”, “user_id”) %>


<%= link_to ‘Back’, posts_path %>

Error:

ArgumentError in PostsController#create

wrong number of arguments (1 for 0)

Thank you for your time

P.S. I tried with the standerd scaffold and that did not work ether (for
what I want to do)

Craig Walker if I knew you I would kiss you (hypothetical), I never knew
it would be so simple however thank you very much.
Robert W. to be truthful I have not got the fogest what I wrote :S,
I looked back over it and thought “yer this is not going to work in a
million years”.

@postform = new(params[:postform])

What is this and what do you expect from it? Do you have a “new” method
that takes one argument in your controller class? Also, the “new” method
of a controller simply renders a blank form to the browser so that the
user can fill it out.

Error:

ArgumentError in PostsController#create

wrong number of arguments (1 for 0)

Typically a controller contains a new method (action) that takes 0
arguments, hence the above error.

@post = Post.new(:title => @postform.title, :body => @postform.body,

:user_id => session[:user_id]).save

P.S. Consider this instead:

@post = Post.create(:title => @postform.title, :body => @postform.body,
:user_id => session[:user_id])
