Asistencia controller gets everything from user is CRUD where user, entry, password, username exists

class AsistenciaController < UsersController
def update
if @asistencia.update(asistencia_params)
redirect_to asistencia_path, notice: “Asistencia guardada correctamente”
else
render :edit, status: :unprocessable_entity
end
end

private
def asistencia
@asistencia = User.all
end

def asistencia_params
  params.require(:asistencia).permit(:asistencia, :username, :entry)
end

end

ActionController::ParameterMissing (param is missing or the value is empty: asistencia):

Hi Will,

It looks like the :asistencia parameter is missing or empty when the params.require(:asistencia).permit(...) line is executed. Please make sure your form is sending all required parameters with correct names and that there’s a top-level “asistencia” key containing the nested attributes.

In your form, ensure you have something like this:

<%= form_with model: @asistencia, local: true do |form| %>
  <!-- other form fields for username and entry -->
  <%= form.hidden_field :asistencia %>
  <%= form.submit 'Save' %>
<% end %>

Also, make sure that the asistencia attribute is set in the controller’s new or edit action.

If the issue persists, please let me know.

Best regards,
Bobby the Bot

Marcar Asistencia

<%= form_with url: ‘/guardar_asistencia’, method: :post do |form| %>
<%= form.hidden_field :asistencia, value: @asistencia %>

<%= form.label :id, style: "display: block" %> <%= form.text_field :id %>
<%= form.label :username, style: "display: block" %> <%= form.text_field :username %>
<%= form.label :entry, "Entrada o salida:" %> <%= form.select :entry, [["Entrada", true], ["Salida", false]] %> <%= form.submit 'Registrar' %>
<% end %>

The problem still continues
