Question

I have a Django project powered by a MySQL database. I fed the database a CSV file (via raw SQL statements) with some 600 records. That went smoothly (almost, there was one error of Field 'customer_id' doesn't have a default value – no idea why). The problem is that these records are not showing up in the webapp itself.

For example, the CSV file contained a list of about 600 records describing client contact info. When I fire up the Django test server and go to the client contact page (which should list all the contact records — the 600) nothing is there. Further, when I go into the Admin section and view the client contact records, there is nothing there — However it shows that there is a total of 600 records right beside the pagination buttons. Also, there are 7 pages (7 pagination buttons) of records — of course, there is nothing on any page.

What the heck?!

EDIT for More Details

The file I am trying to import is called subset_ressy_esc.csv and a couple of lines of it look like this:

R0138,Y,1432 MyRoad Ct,MyCity, MyProv,H0H 0H0,N,100.00,0,1,1
R0140,Y,268 MyStreet Link,MyCity,MyProv,H0H 0H0,N,100.00,0,1,1
R0142,Y,10994 123 St,MyCity,MyProv,H0H 0H0,N,0.00,1,0,0

And the fields they represent (in the same order shown above) are:

systemID (pk), isRessy, systemAddress, systemCity, systemProvince, systemPostalCode, isHoseBibb, servicePreauthAmt, noWorkRequired, SUAuthorized, BDAuthorized

Now the isRessy and isHoseBibb fields are select style fields, where the user selects from a drop down, while the noWorkReqd, SUAth, and BDAuth are booleans. The serviceAmt is a decimal (dollar) amt.

To import this data, I go into the mySql interpreter mysql -u garfonzo -p and run the following command:

mysql> load data local infile '/home/garfonzo/subset_ressy_esc.csv' into table systems_system fields terminated by ',' lines terminated by '\n' (systemID, isRessy, systemAddress, systemCity, systemProvince, systemPostalCode, isHoseBibb, servicePreauthAmt, noWorkRequired, SUAuthorized, BDAuthorized);
Query OK, 684 rows affected, 1 warning (0.01 sec)
Records: 684  Deleted: 0  Skipped: 0  Warnings: 0

mysql> show warnings;
+---------+------+-----------------------------------------------------+
| Level   | Code | Message                                             |
+---------+------+-----------------------------------------------------+
| Warning | 1364 | Field 'systemOwner_id' doesn't have a default value |
+---------+------+-----------------------------------------------------+

When I do a SELECT * FROM systems_system I spits out all 684 records, with all the right data. When I open the django project, nothing is listed but the admin has 7 pages of systems, without a single system actually present — just 7 pages of nothing.

Any ideas?

Answer 1

Looking at the warning of Field systemOwner_id doesn’t have a default value didn’t really bother me. But it suddenly dawned on my that I am not importing a value for that field, and that field cannot be empty. So, (for testing purposes) I changed my model so that that field systemOwner_id can be null, ran the same MySQL import and, voila, all systems are present. Nice!!

Thanks for the help — working through this on this Q&A has helped solve my problem.

Cheers!
