I run this code to import a large csv file into a table in Postgres:
connection = ActiveRecord::Base.connection.raw_connection
connection.exec(%q[COPY import_xp_raw_bill_details FROM STDIN
DELIMITERS ',' CSV])
data = File.open(file_path).read
data.each_line {|line| connection.put_copy_data(line)}
connection.put_copy_end
In the code, after that in the same method I call the db via AR again to
confirm the records loaded (I have confirmed it can be any method, even the
most simple AR find... lets say 'User.all'), and I get the error below (note
that I have determined the error is due to the specific file I am importing,
as the code works for other files.... I would rather though get a real
message from Postgres if it is availalble rather than do trial and error to
find the issue with the specific file).
(rdb:1) User.all
ActiveRecord::StatementInvalid Exception: PGError: ERROR: current
transaction is aborted, commands ignored until end of transaction block :
SELECT "users".* FROM "users"
>From experience I know this means I made the god of PG unhappy and I am not
allowed back for now as a punishment. However I can not seem to retrieve a
specific error from the connection object above. I do see an
ActiveRecord::Base.connection.raw_connection#error_message method, but it
returns an empty string.
Anyone have an idea where else to look.... I have read the whole method list
for this object (ActiveRecord::Base.connection.raw_connection) and tried
everything that looked promising.
Thanks,
David
