    <% = form_for (@kome, url: {controller: 'ugblogs', action: 'show'}) do | form |%>
    1) You can receive post contents by show, but the process is not written in show. I think that this is the place where you usually get with create.
    But
    That is not Ugsama, but Ugblog create. . .
    I can jump to Ugsama's create and return to the Ugblog show from there.

    Whenresources: ugsamais set in routes.rb,
    for post Since ugsama_path can be created, pass (ugblog_id: @udblog) to it.
