Hi,
I have two entities: Installation and Command. Each installation can
have many commands. In order to create a command the user has to go
through the installation. I have generated the standard scaffold code
for command and I changed the two actions New and Create in the
commands_controller as follows:
def new
session[:installation_id] = params[:id] #I added this
@command = Command.new
end
def create
@command = Command.new(params[:command])
@installation = Installation.find(session[:installation_id]) #I added
this
@command.installation = @installation #I added this
if @command.save
flash[:notice] = ‘Command was successfully created.’
redirect_to :action => ‘list’
else
render :action => ‘new’
end
end
In the installation list view I have a link for each listed installation
that calls the command new action passing the installation id. In the
new command action I save this id in the session and when create is
called I retrieve the id and assign set the command to be relation with
that installation.
Is this a good practice? Is there another maybe more proper way of doing
what I did?
Thank you,
