 else
   render :action => ''resolve''

Problem is in parameters arguments...

It should be params[:resolve] ....not params[:resolve1]...

Hi Ralu rm

The reason for this error is in the line
> <%= form_tag :action => ''resolve_create'', :resolve
=> @resolve %>
   Since this will generate source like
action="/controller/resolve_create?resolve="

And in resolve_create what you are trying is
> @resolve = Resolve.new(params[:resolve])
> if @resolve.save
   Here the error is .Why are you passing :resolve => @resolve  ?

Try below code

<%= form_tag :action => ''resolve_create'' do %>
   <p>resolution:<br />
   <%= text_area ''resolve'',''content'',
:cols => 40, :rows => 12  %></p>
 <%= submit_tag "save" %>

Hi Ralu rm

    That is already there in params[:resolve]

Sorry to butt in guys, i get the feeling you''re going to go round in 
circles forever.

Ralu - if the user types ''foo'' in the text box, params will
look like
this:

params = {:resolve => {:content => "foo"}}

In the controller you need to do this:

 @resolve = Resolve.new(params[:resolve])

which is the same as saying this

  @resolve = Resolve.new({:content => "foo"})

which in turn, effectively does this

@resolve = Resolve.new
@resolve.content = "foo"

Do you see?

Like Sijo says, you don''t need :resolve => @resolve in the form -
this
is going to break the form by overriding :resolve in your params, 
effectively deleting the parameter from the text field.  It would be 
better if you sticked to the standard restful scheme and your form 
looked like this:

<% form_for @resolve do |f| %>
   <p>resolution:<br />
   <%= f.text_area ''resolve'',''content'',
:cols => 40, :rows => 12  %></p>
<% end %>

This will submit to the ResolveController.create action, which is where 
you should create a resolve object/

Oops, sorry, that text area in the amended form should be

<%= f.text_area :content, :cols => 40, :rows => 12  %></p>

I know you''re a beginner, but if you know the name of the method that 
you have a question about, your first stop should always be the api.
