Try changing this
new_student_student_previous_datum_path(@student)
to
new_student_student_previous_datum_path(student_id: @student.id)
if it still throws the error, paste me the complete routing error.
UPDATE:
the error is in the view this url for the form currently is
This one is generating the error of the :action : “show”
change it for
new_student_student_previous_datum_path(@student)
<%= bootstrap_form_for(@student_previous_data, :url => new_student_student_previous_datum_path(@student),
html: { class: 'form-horizontal' }, :method => "post") do |f| %>
the new and create actions share the same path but the action is defined by the method of the request post or get
