Does anyone have any thoughts on a cleaner way to achieve the
following in a controller ...
def show
if current_user.can_access_organisation(params[:id])
@organisation = Organisation.find(params[:id])
end
respond_to do |format|
format.html # show.html.erb
format.xml { render :xml => @organisation }
end
end
As you can see I am testing to make sure the current user is able to
access an organisation, however the site breaks when the test is
broken which doesn't look very nice.
You only set @organisation to a value if the user can access the
organization...so sometimes @organization is nil and you'll have an
error when trying to access it.
try something like this to make sure you don't try to access a nil
value.
if can access
@organisation =
respond_to do |format|
format.html # show.html.erb
format.xml { render :xml => @organisation }
end
else
respond_to do |format|
format.html { redirect_to, or render an error of some sort }
format.xml { redirect_to, or render an error }
end
end
