I enabled hstore using the below code.
class SetupHstore < ActiveRecord::Migration
def self.up
execute "CREATE EXTENSION IF NOT EXISTS hstore"
end
def self.down
execute "DROP EXTENSION IF EXISTS hstore"
end
end
Once I migrated the file 'enable_extension hstore' line appeared in schema file.
But when I used the same code in another system i got an error like
ActiveRecord::StatementInvalid: PG::UndefinedObject: ERROR: type "hstore" does not exist
By droping that schema and migrating it also i tried to enable it but still its not working.

I'm using Django 2.1 with MySQL.
I have one custom SQL view, which is bound with a model with Meta managed = False. Django's TestCase has no idea how the view is created, so I'd like to provide SQL command to create this view. The best option would be to do this on database create, but I have no idea how to do that.
What I've done so far was to override TestCase's setUp method. It looks like that:
class TaskDoneViewTest(TestCase):
def setUp(self):
"""
Create custom SQL view
"""
cursor = connection.cursor()
file_handle = open('app/tests/create_sql_view.sql', 'r+')
sql_file = File(file_handle)
sql = sql_file.read()
cursor.execute(sql)
cursor.close()
def test_repeatable_task_done(self):
# ...
def test_one_time_task_done(self):
# ...
I've got this solution from similar SO post: How to use database view in test cases. It would be a nice temporary solution, but the problem is with all those 2 test cases active I'm getting following error:
$ python manage.py test app.tests
Creating test database for alias 'default'...

For some reason this error doesn't happen when I have only one test case active (why?).This error remains until I change my test's base class from TestCase to TransactionTestCase.
Well, I would ask why this happen and if there is any solution to get it okay with simple TestCase class, because my test for now has nothing to do with transactions and I find this working solutions a bit too dirty, but...
I would more likely stick to the main issue, that is, to globally (for all my test cases) do the following thing:
When testing database is created, do one more custom SQL from provided file. It is going to create required view
Can you please help me how to do that?
If you read the documentation for TestCase, you'll see that it wraps each test in a double transaction, one at the class level and one at the test level. The setUp() method runs for each test and is thus inside this double wrapping.
As shown in the above mentioned docs, it is suggested you use setUpTestData() to set up your db at the class level. This is also where you'd add initial data to your db for all your tests to use.
I want to upload a string in unicode to my sql server. I'm using python 2.7.6, sqlalchemy-migrate 0.7.2, pymssql 2.1.2.
But when I saved my object I got an OperationalError from sqlalchemy
OperationalError: (OperationalError) (105, "Unclosed quotation mark

With more detail I'm guesssing is from my Description value :

I saw a big U and not u, the character is the gift unicode just before, the "\u270e" works well and show a pencil. I strongly thing is because of the 8 values versus 4 for others.
But how to prevent this error ?
The column description inside of my DB is a nvarchar(2000)
I'm using Using flask restful reqparse to parse the argument create sync the object from the DB and save it :
parser_edit.add_argument('Name',
type=unicode,
required=True,
location='json')
parser_edit.add_argument('Description',
type=unicode,
required=False,

I am trying to catch an error while running a rails migration (rake db:migrate) so that it can fail silently.
I want to enable the RDKit extension on my PostgreSQL database, but only if it is available in the PostgreSQL installation. My rescue code is being run, however rake is still aborted. I tried this:
class EnableExtensionRdkit < ActiveRecord::Migration
def up
begin
ActiveRecord::Base.connection.execute("CREATE EXTENSION rdkit;")
rescue => error
p "NO RDKit SUPPORT due to exception: "+error.to_s
end
def down
ActiveRecord::Base.connection.execute("DROP EXTENSION IF EXISTS rdkit;")
end
end
But I get this error:
$ rake db:migrate
== EnableExtensionRdkit: migrating ===========================================
NO RDKit SUPPORT due to exception: PG::UndefinedFile: ERROR: could not access file "$libdir/rdkit": No such file or directory
: CREATE EXTENSION rdkit;

rake aborted!

I found a way to make it stop failing. I suspected that the keyword could be 'transaction'. So I added the disable_ddl_transaction!() to the above EnableExtensionRdkit class. This fixed the problem and left me with the desired output:
$ rake db:migrate
== EnableExtensionRdkit: migrating ===========================================
NO RDKit SUPPORT due to exception: PG::UndefinedFile: ERROR: could not access file "$libdir/rdkit": No such file or directory

Hope someone can use this!
I am working through the tutorial for setting up Djapian and am trying to use the indexshell (as demonstrated in this step). When I run the command 'list' I get the following output:
Installed spaces/models/indexers:
- 0: 'global'
I therefore cannot run any queries:
>>> query
No index selected
Which leads me to attempt:
>>> use 0
Illegal index alias '0'. See 'list' command for available aliases
My index.py is as follows:
from djapian import space, Indexer, CompositeIndexer
from cms.models import Article
class ArticleIndexer(Indexer):
fields = ['body']
tags = [
('title', 'title'),
('author', 'author'),
('pub_date', 'pub_date',),
('category', 'category')
]
space.add_index(Article, ArticleIndexer, attach_as='indexer')
Update: I moved the djapian folder from site-packages to within my project folder and I move index.py from the project root to within the djapian folder. When I run 'list' in the indexshell the following is now returned:
>>> list
Installed spaces/models/indexers:
- 0: 'global'
- 0.0 'cms.Article'
-0.0.0: 'djapian.space.defaultcmsarticleindexer'
I still cannot do anything though as when I try to select an index I still get the following error:
>>> use 0.0
Illegal index alias '0'. See 'list' command for available aliases
Update 2: I had a problem with my setting for DJAPIAN_DATABASE_PATH which is now fixed. I can select an indexer using the command 'use 0.0.0' but when I try to run a query it raises the following ValueError: "Empty slice".
Have you fixed the problem of the ValueError: Empty Slice?
I'm having the exact same problem using the djapian tutorial. First I was wondering if my database entries were right, but now I'm thinking it might have something to do with the actual querying of the Xapian install?
Seeing that I haven't had to point to the install at all wonders me if I placed it in the right directory and if djapian knows where to find it.
-- Edit
I've found the solution, atleast for me. The tutorial is not up to date and the query command expects a number of results too. So if you use 'query mykeyword 5' you get 5 results and the ValueError: Empty Slice disappears. It's a known issue and it will be fixed soon from what I read.
Perhaps you're not loading indexes?
You could try placing the following in your main urls.py:
import djapian
djapian.load_indexes()
In a comment to your question you write that you've placed index.py file in the project root. It should actually reside within an app, along models.py.
One more thing (which is very unlikely to be the cause of your problems); you've got a stray comma on the following line:
('pub_date', 'pub_date',),
