I'm using Django 1.9.7 with Postgresql.
When I try to migrate a relation between two tables in different schemas,
for example: a table named ''**product**'', which is in a schema named
''**dataflex**'' and another table named ''**client_product_sale_stc**''
in another schema.
I got this error:
----
django.db.utils.ProgrammingError: ERRO: syntax error at or near
"dataflex"
LINE 1: ...CONSTRAINT "client_product_setor_id_52aad07a_fk_"dataflex"....
----
After sometime trying to figure It out a solution for this problem, I
tried to change the schemas's name to just ''**df**'' instead of
''**dataflex**'' and It worked perfectly.
I also tried to decreased table's name size and It worked just like when I
decreased schema's name size, so It seems to be a problem with big
constraints names.
I'm using the following syntax:
db_table = '"dataflex"."product"'
**setor_id** is the name of the field of the relation in
client_product_sale_stx model/table.
product model/table does not have a field for the relation.
**Examples models:**
{{{
class ClientProductSaleStc():
setor_id = models.ForeignKey(Product, db_column='setor_id')
class Meta:
db_table = 'client_product_sale_stc'
class Product():
recnum = models.BigIntegerField(unique=True)
hor_due = models.DecimalField(max_digits=2, decimal_places=0)
min_due = models.DecimalField(max_digits=2, decimal_places=0)
class Meta:
db_table = '"dataflex"."product"'
}}}
