This looks wrong:
def create
@vorlesung=Vorlesung.create(params[:vr])
What the hell is :vr?
What version of rails are you using? In rails 3, you would write:
<%= form_for(@vorlesung) do |v| %>
Name : <%= v.text_field :name, "Name:" %> <br>
Name de Professur : <%= v.text_field :leiter_name, "Leiter name:"
%><br>
<%= v.submit 'Speicher'%>
<% end %>
===
With that form, rails will create name attributes for your html elements
like this:
name="vorlesung[name]"
name="vorlesung[leiter_name]"
You can verify that by doing "View Source' in your browser after the
page loads. So the name of the form_for() variable, e.g. @vorlesung,
because the first part of the name attribute, and the symbol you
specified for the html element, e.g. :name, becomes the subscript. As a
result, in your controller you can get a hash of the all the name
attributes and the corresponding values entered into the form, like
this:
@attributes = params[:vorlesung]
which will look something like this:
{ :name => 'Joe', :leiter_name => 'Blow' }
Therefore, in your controller you can do this:
def create
@vorlesung = Vorlesung.new(params[:vorlesung])
if @vorlesung.save
...
end
