Invalid predicate

[lunks]

Hello, I've got a form field like this:

    <%= search_form_for @q, :url => dashboard_index_path do |f| %>
      <%= f.grouping_fields @q do |f| %>
        <%= f.hidden_field_tag :or, 'or' %>
        <%= f.text_field :status_signal_strength_gt %>
        <%= f.text_field :status_signal_strength_lt %>
        <%= f.text_field :status_battery_level_gt %>
        <%= f.text_field :status_battery_level_lt %>
        <%= f.text_field :status_sd_card_gt %>
        <%= f.text_field :status_sd_card_lt %>
        <%= f.text_field :status_application_gt %>
        <%= f.text_field :status_application_lt %>
        <%= f.text_field :status_available_ram_mem_gt %>
        <%= f.text_field :status_available_ram_mem_lt %>
      <% end %>
      <%= f.grouping_fields @q do |f| %>
        <%= f.hidden_field_tag :any, 'any' %>
        <%= f.select :status_network_name %>
        <%= f.text_field :status_network_type %>
        <%= f.text_field :gadget_name %>
        <%= f.text_field :gadget_model_name %>
        <%= f.text_field :gadget_model_type_name %>
      <% end %>
      <%= f.submit %>

@q is associatiated with telepone, which has a status.

Status schema is:

  create_table "statuses", :force => true do |t|
    t.integer  "company_id"
    t.integer  "telephone_id"
    t.decimal  "battery_level"
    t.datetime "created_at"
    t.datetime "updated_at"
    t.string   "os"
    t.string   "os_version"
    t.string   "imei"
    t.string   "imsi"
    t.string   "network_type"
    t.string   "network_name"
    t.integer  "lac"
    t.string   "app_version"
    t.integer  "signal_strength"
    t.integer  "available_ram_mem"
    t.integer  "total_application_storage",     :limit => 8
    t.integer  "available_application_storage", :limit => 8
    t.integer  "total_sd_card_storage",         :limit => 8
    t.integer  "uptime",                        :limit => 8
    t.integer  "available_sd_card_storage",     :limit => 8
    t.integer  "sd_card"
    t.integer  "application"
  end

But I get No valid predicate for status_network_name when trying to submit the form. What am I doing wrong?

Nevermind, forgot the actual_predicate :P

I'm having the same annoying error, I don't find any documentation about how to solve.

@lunks what did you do?

[fguillen]

Ah!.. I found it.. you have to modify your field names and add them prefixes like _cont or _start... https://github.com/ernie/ransack/blob/master/lib/ransack/constants.rb
