"PG::Error - numeric field overflow" on Heroku - ruby-on-rails

I have built an app that queries Google Analytics for the last 7 days of data. Everything works locally. On Heroku, the process runs smoothly until it tries to get data for today's date. I then get the following error:
2012-10-29T02:32:02+00:00 app[web.1]: ActiveRecord::StatementInvalid (PG::Error: ERROR: numeric field overflow
2012-10-29T02:32:02+00:00 app[web.1]: DETAIL: A field with precision 8, scale 2 must round to an absolute value less than 10^6.
I have tried to figure out which variable it's not happy with but I don't know right now. I am assuming it's something related to date or time.
Any thoughts or ideas would be great :)

ActiveRecord::Schema.define(:version => 20121014153338) do
create_table "analytics", :force => true do |t|
t.string "site"
t.integer "visits"
t.date "start_date"
t.date "end_date"
t.decimal "revenue_per_transaction", :precision => 8, :scale => 2
t.integer "transactions"
t.decimal "item_quantity", :precision => 8, :scale => 2
t.integer "goal_starts"
t.integer "goal_completes"
t.decimal "goal_conversion", :precision => 8, :scale => 2
t.datetime "created_at", :null => false
t.datetime "updated_at", :null => false
t.decimal "goal_abandon", :precision => 8, :scale => 2
t.decimal "revenue", :precision => 8, :scale => 2
t.string "source"
end
end

You have a numeric field with typmod numeric(8,2) and you're trying to store a value greater than 999999.99 in it. See the PostgreSQL manual on NUMERIC for information on numeric scale and precision, which are the qualifiers shown after the type in parentheses.
This earlier question appears to cover the same issue with Rails, showing the Rails model and how the scale and precision are assigned.
NUMERIC isn't a date/time field, it's a number field.
Demo of the issue:
regress=> SELECT NUMERIC(8,2) '999999.99';
numeric
-----------
999999.99
(1 row)
regress=> SELECT NUMERIC(8,2) '1000000.00';
ERROR: numeric field overflow
DETAIL: A field with precision 8, scale 2 must round to an absolute value less than 10^6.
It's a pity that Pg doesn't tell you what field this is when it is a field. It's difficult for it to do so, though, because it doesn't usually know which value is going to go into which field when it's parsing string literals. Enable log_statement = 'all' in postgresql.conf, ALTER USER ... SET, ALTER DATABASE ... SET, or per-session with SET log_statement = 'all' then re-test and examine the query logs.
Also look at the table definitions with \dt in psql to see what might have the type numeric(8,2) and could be causing the problem.
As for why it works locally: Is the local DB PostgreSQL? Some Rails users seem to have a very odd setup where they use SQLite locally, and PostgreSQL on Heroku. This is a recipe for chaos and deployment problems. Use the same database in development and testing. If it is PostgreSQL locally, is it the same version?

Ruby on Rails Testing - ActiveRecord::StatementInvalid: PG::InvalidTextRepresentation: ERROR: malformed array literal:

I have a project that is running ok on production and development and mostly on many tests, but with one model there's no way to run the tests.
Model:
create_table "cities", force: :cascade do |t|
t.string "city"
t.string "cp", array: true
t.datetime "created_at", null: false
t.datetime "updated_at", null: false
t.string "name"
t.string "primary_cp"
end
(Note that "cp" attribute is an Array and I'm using Postgres on the project)
(I'm NOT setting "serialize: cp, Array" on the model)
But when I run rails test/models/city_test.rb what I get is
Error:
CityTest#test_the_truth:
ActiveRecord::StatementInvalid: PG::InvalidTextRepresentation: ERROR:
malformed array literal: "MyString"
LINE 28: ...d_at") VALUES (980190962, 'MyString', 'MyString',
'MyString'...
^
DETAIL: Array value must start with "{" or dimension information.
: DELETE FROM "homes";
DELETE FROM "categories";
DELETE FROM "volunteers";
DELETE FROM "donations";
I've already searched for other solutions here but it doesn't fix the problem. What I'm guessing is that it is something related to the YAML serialization that the test environment does, but I'm not quite sure.
I have no problem with development and production environments at all, it only happens on test env.
For those who came up with same situation. the problem was with the declaration of the test fixtures. An array in YAML must be declared this way:
one:
city: Premià de Mar
cp:
- 08400
- 08401
two:
city: Mataró
cp:
- 08300
- 08301
Where "cp" is the array. Setting up the array properly fixes the issue.

postgreSQL date records only persisting up to a certain point in time in Rails

I am seeding some simple data in my rails program that is using a postgres database.
Currently, it is only persisting certain dates to the database. Other times, it is showing up as null in my API, which is very odd. I will post a picture of my database, and the seeded data, as well as my JSON API.
Here is my table:
create_table "pickup_deliveries", force: :cascade do |t|
t.date "pickup_date"
t.text "pickup_location"
t.money "rate", scale: 2
t.date "delivery_date"
t.text "delivery_location"
t.boolean "local"
t.datetime "created_at", null: false
t.datetime "updated_at", null: false
t.integer "loaded_miles", default: 0
t.integer "deadhead_miles", default: 0
end
Here is my seeded data:
PickupDelivery.create(:pickup_date => '05-10-2019', :pickup_location => 'Kansas City, MO', :rate => '550.00', :delivery_date => '05-11-2019', :delivery_location => 'Wichita, KS', :local => false, :loaded_miles => '550', :deadhead_miles =>'230');
PickupDelivery.create(:pickup_date => '05-20-2019', :pickup_location => 'Kansas City, MO', :rate => '550.00', :delivery_date => '05-25-2019', :delivery_location => 'Wichita, KS', :local => false, :loaded_miles => '550', :deadhead_miles =>'230');
Here is the persisted data in my JSON API:
[
{
id: 1,
pickup_date: "2019-10-05",
pickup_location: "Kansas City, MO",
rate: "550.0",
delivery_date: "2019-11-05",
delivery_location: "Wichita, KS",
local: false,
created_at: "2019-05-09T16:14:35.312Z",
updated_at: "2019-05-09T16:14:35.312Z",
loaded_miles: 550,
deadhead_miles: 230
},
{
id: 2,
pickup_date: null,
pickup_location: "Kansas City, MO",
rate: "550.0",
delivery_date: null,
delivery_location: "Wichita, KS",
local: false,
created_at: "2019-05-09T16:14:35.319Z",
updated_at: "2019-05-09T16:14:35.319Z",
loaded_miles: 550,
deadhead_miles: 230
}
]
As you can see, the dates were both inputted in the same format, but only one came out as intended while the other came out as null
Thanks for reading.
The reason is that you are passing an invalid format in the second record
# Record 1
:delivery_date => '05-11-2019' # dd-mm-yyyy
# to
delivery_date: "2019-11-05"
# Record 2
:delivery_date => '05-25-2019' # dd-mm-yyyy
# Invalud since there is no month 25
so it becomes nil
This date is being parsed as dd-mm-yyyy
The date you are passing in the second record is invalid due to the month
I suggest you pass the date in this format 'dd-mm-yyyy' - '20-05-2019'
NOTE: Even in your first record the date in being parsed as 05 the day, 11 as the month and 2019 as the year

ruby 1.9.3 round decimals

I'm using round(2) to round the decimals but for some reason when I do that in my controller, randomly it convert it. If I try this in rails console then it converts it to 651.44
Here is what I'm using in my rails migration
t.decimal :balance, :precision => 8, :scale => 2, :null => false

Unset operation failing for MongoMapper model, cannot delete / remove key from model

We're on mongodb 2.0.0, mongo gem 1.4.1, mongo_mapper 0.9.2, rails 3.0.6.
We love MongoMapper, but we need helping resolving one nasty issue: we have a key carried over from some testing, but invoking obj.unset fails to do anything.
Specifically, we are trying to remove an "id" key (not "_id") because it's causing MM to treat obj.id as different from obj._id, which we don't want.
After clearing out the database, we ran these commands from a controller which does nothing else: (We also tried running the same code from the rails console, but it also fails.)
logger.info "#{Game.keys.keys.inspect}"
Game.unset({}, :id)
logger.info "#{Game.keys.keys.inspect}"
Game.unset(:id)
logger.info "#{Game.keys.keys.inspect}"
Output:
["jackpot", "players", "created_at", "puzzles", "ended_at", "player_index", "updated_at", "log", "_id", "id", "join_code", "puzzle_index"]
["jackpot", "players", "created_at", "puzzles", "ended_at", "player_index", "updated_at", "log", "_id", "id", "join_code", "puzzle_index"]
["jackpot", "players", "created_at", "puzzles", "ended_at", "player_index", "updated_at", "log", "_id", "id", "join_code", "puzzle_index"]
Current keys defined in our Game model:
key :players, Array, :default => []
key :player_index, Integer, :default => 0
key :puzzles, Array, :default => []
key :puzzle_index, Integer, :default => 0
key :join_code, String, :default => nil
key :jackpot, Integer, :default => 0
key :log, Array, :default => []
key :created_at, Time
key :updated_at, Time
key :ended_at, Time, :default => nil
Help?
Thanks!
It pains us to post the answer since this solidifies our status as "morons, idiots, fools, noobs, Jay Leno fans," but in case anyone else bumps into the same issue: while our model directory was clean in the dev environment, the model dir in the production environment contained old test files ... which contained an old model with the "id" key.
Obviously, removing the old files and the old models solved everything, though we're left with staggering bruises to our egos and to our heads (from excessive banging against the walls).

Viewing the contents of tables in schema.rb in rails

I'm sorry if this is a stupid question, but in my schema.rb I have several tables like
create_table "messages", :force => true do |t|
t.integer "user_id", :null => false
t.string "message", :null => false
t.datetime "created_at", :null => false
t.string "photo_file_name"
t.string "photo_content_type"
t.integer "photo_file_size"
t.datetime "photo_updated_at"
end
Is it possible to view the contents of each table i.e view each message and associated user id, message content, time created at, linked image, etc?
Thanks
A database schema represents the structure of the database, not the content of it.
If you want to access the content in your database, you would query it to do so. You can do that via command line clients (running $ rails dbconsole will try to open one for the configured database) or graphical tools like Sequel Pro (for MySQL on Mac OS X).
You can also get this through your Rails application by running $ rails console and then using the methods available through ActiveRecord (e.g. Post.all or User.where(:name => 'Billy').limit(5)).
You can use gem "annotate". It is very helpful for me.
For viewing the table structure on the rails console only need to run the table name eg If there is a table with name country. only run the 'Country '
2.4.4 :004 > Country
=> Country(id: integer, name: string, percentage: string, created_at: datetime, updated_at: datetime, is_sync: boolean)
2.4.4 :005 >
