I had the same thought, but while WeatherObservation has a
start_time_id, but it doesn't have a start_time slot. Is AR being
clever about foreign key references? Here's the schema:
create_table "weather_observations", :id => false, :force => true do
|t|
t.integer "start_time_id"
t.integer "end_time_id"
t.integer "weather_station_id"
t.float "temperature_max_c"
t.float "temperature_avg_c"
t.float "temperature_min_c"
t.float "dewpoint_max_c"
t.float "dewpoint_avg_c"
t.float "dewpoint_min_c"
t.float "humidity_max"
t.float "humidity_avg"
t.float "humidity_min"
t.float "pressure_max_kpa"
t.float "pressure_avg_kpa"
t.float "pressure_min_kpa"
t.float "windspeed_max_mps"
t.float "windspeed_avg_mps"
t.float "gustspeed_max_mps"
t.float "precipitation_m"
end
