  def update

    @ticket = Ticket.find(params[:id])     if @ticket.update_attributes(params[:ticket])         redirect_to :action => 'list'     else   redirect_to :action => 'edit'     end   end   def resolve     @ticket = Ticket.find(params[:id])     @category = Category.find(params[:id2])     @urgency = Urgency.find(params[:id3])     @resolve = Resolve.new   end

  def resolve_create   @resolve = Resolve.new(params[:resolve1])   if @resolve.save     redirect_to :action => 'list'   else     redirect_to :action => 'resolve'   end   end

end

this is the part of controller code...

def resolve_create @resolve = Resolve.new(params[:resolve1]) if @resolve.save redirect_to :action => ‘list’ else render :action => ‘resolve’ end end

u can try the above code…

Thanks seenu.

Otherwise u can try this one

def resolve_create

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

if @resolve.save

redirect_to :action => 'list'

else

render :action => ‘resolve’

end

end

Thanks seenu

  def resolve_create   @resolve = Resolve.new(params[:resolve1])   if @resolve.save     redirect_to :action => 'list'   else     redirect_to :action => 'resolve'   end   end

Problem is in parameters arguments...

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

Thanks Brijesh Shah

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 ?

Sijo

then how can i pass the value resolve which iam getting from the user ?

is dat iam going in a rubbish way...???

am just a beginner, dats y dat quest buddy... anyway thanks for the link!

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.
