Error :
ActiveRecord::RecordNotFound in UsersController#show

Couldn't find User without an ID
Please help it must help full for edti.html.erb

Note that the error is in UsersController#show so it is nothing to do
with show.html.erb as it has not got there yet. Since all you are
doing in show is finding a record by id and the error says that the
record was not found it seems likely that the error is with
params[:id]. Have a look in development.log and see what parameters
are being passed to show.

Can you not see the problem? There is no id in the parameters.
Given that it is not surprising that User.find(params[:id]) fails
saying that there is no id.
