Oh, where to begin. Unless I'm completely daft, I see only one single
line in your new method that belongs in a "new" action.
This one:
@project = Project.new
Compare your method with what a new method should look like in a
controller:
Example:
# GET /presentations/new
# GET /presentations/new.xml
def new
@presentation = Presentation.new
respond_to do |format|
format.html # new.html.erb
format.xml { render :xml => @presentation }
end
end
The new method of a controller serves one purpose (following the single
responsibility principal). That purpose is to GET the blank form. In
other words the blank form is considered to be a resource that request
using a GET method having a resource identifier similar to:
http://example.com/presentations/new
Take note that the @presentation object is used only for context to draw
the form. When the form is submitted that instance of @presentation gets
thrown away. A new instance is then initialized at the beginning of the
"create" method as you can see in the following example:
Example:
# POST /presentations
# POST /presentations.xml
def create
@presentation = Presentation.new(params[:presentation])
respond_to do |format|
if @presentation.save
flash[:notice] = 'Presentation was successfully created.'
format.html { redirect_to(@presentation) }
format.xml { render :xml => @presentation, :status => :created,
:location => @presentation }
else
format.html { render :action => "new" }
format.xml { render :xml => @presentation.errors, :status =>
:unprocessable_entity }
end
end
end
Your "new" method seems to be attempting to take on both
responsibilities. I know there is such a thing as a post-back pattern,
but the sorts of problems you're having now are why that pattern is
strongly discouraged in modern web application design.
Besides all that, if all you're attempting to do is set a default state
for your boolean fields when creating new records, then set a default
state in your migration (... :default => false).
