* gn3/db/sample_data.py (__extract_actions): An update on a vector of data can
contain: inserts, deletes and updates. This functions extracts these actions
during an update.
* tests/unit/db/test_sample_data.py (test_extract_actions): Add test-case for
the above.
|
|
* gn3/db/sample_data.py (insert_sample_data)[__insert_data]: Move check to the
main body. With this check here, you have 3 redundant checks. For a successful
insert, it will insert the first value to the `PublishData` table and ignore the
rest of the inserts.
|
|
* gn3/db/sample_data.py: Now constant, `_MAP`.
(delete_sample_data)[__delete_data]: Replace `_map` with `_MAP`.
(insert_sample_data)[__insert_data]: Ditto.
|
|
|
|
* gn3/db/sample_data.py (insert_sample_data): Use correct query string. Also,
use CaseAttributeId to determine whether case-attributes were inserted. If so,
do not attempt an insert.
|
|
* gn3/db/sample_data.py (insert_sample_data)[__insert_case_attribute]: Remove
extra parameters.
|
|
|
|
* gn3/db/sample_data.py (insert_sample_data): If data already exists in the
table, do not attempt an insert; otherwise, an error will be generated.
|
|
* gn3/db/sample_data (get_sample_data_ids): Add an extra condition that caters
for inserts: during inserts, joins won't work when fetching the strain_id,
publishdata_id, and strain_name. In this case, just create 2 separate queries
to do that work.
|
|
* gn3/csvcmp.py (extract_strain_name): New function.
* gn3/db/sample_data (delete_sample_data): Use the aforementioned function.
(insert_sample_data): Ditto.
* tests/unit/test_csvcmp: Test cases for above.
|
|
* gn3/db/sample_data.py (delete_sample_data): Modify this function to allow
deleting case-attribute values.
|
|
* gn3/db/sample_data.py (insert_sample_data): Modify this function to allow
inserting case-attribute values.
|
|
* gn3/db/sample_data.py (get_sample_data_ids): Extend to also fetch
InbredSetId.
(update_sample_data): Discard the returned value of InbredSetId.
(delete_sample_data): Ditto.
|
|
* gn3/db/sample_data.py: Import Any, Tuple.
(get_sample_data_ids): New function that fetches the strain_id and
publishdata_id of a given data point.
(update_sample_data): Use `get_sample_data_ids`.
(delete_sample_data): Ditto.
(insert_sample_data): Ditto.
|
|
|
|
* gn3/db/traits.py (get_trait_csv_sample_data): Update SQL to fix runtime
errors.
|
|
|
|
|
|
* gn3/db/traits.py (get_trait_csv_sample_data): Fetch case attribute data if
it exists.

* Use `with` in place of plain `open`
* Use f-strings in place of `str.format()`
* Remove string interpolation from queries - provide data as query parameters
* other minor fixes

Test that the partial correlations endpoint handles a mix of existing and
non-existing control traits gracefully and issues a warning to the user.
Summary of changes:
* gn3/computations/partial_correlations.py: Issue a warning for all
non-existing control traits
* gn3/db/partial_correlations.py: update queries - use `INNER JOIN` for tables
instead of comma-separated list of tables
* tests/integration/conftest.py: Add `db_conn` fixture to provide a database
connection to the tests. This will probably be changed in the future to
connect to a temporary database for tests.
* tests/integration/test_partial_correlations.py: Add test to check for
correct behaviour with a mix of existing and non-existing control traits
|
|
Test that if the endpoint is queried and not a single one of the control
traits exists in the database, then the endpoint will respond with a
404 (not-found) status code.
Summary of changes:
* gn3/computations/partial_correlations.py: Check whether any control trait is
found. If none is found, return "not-found" message.
* gn3/db/partial_correlations.py: Fix bug in Geno query.
* tests/integration/test_partial_correlations.py: Add test for non-existing
control traits. Rename function to make it clearer what it is testing
for. Remove obsoleted comments.

The code was migrated from GN1 with a faulty assumption that all trait types
have a corresponding `*Freeze` table in the database. This assumption is not
true for the `Temp` traits.
This commit removes the buggy code.
|
|
Test that the partial correlations endpoint responds with an appropriate
"not-found" message and the corresponding 404 status code in the case where a
request is made and the primary trait requested for does not exist in the
database.
Summary of the changes in each file:
* gn3/api/correlation.py: generalise the building of the response
* gn3/computations/partial_correlations.py: return with a "not-found" if the
primary trait does not exist in the database
* gn3/db/partial_correlations.py: Fix a number of bugs that led to exceptions
in the case that the primary trait did not exist
* pytest.ini: register a `slow` pytest marker
* tests/integration/test_partial_correlations.py: Add a new test to check for
an appropriate 404 response in case of a primary trait that does not exist
in the database.

If a user replaces an individual value with an "x", delete that date entry
from the respective table. Deletion here is the only option since by default
the Nstrain, PublishData and PublishSE don't accept null values. Note that
deleting all 3 values is equivalent to removing the sample from the CSV file.
* gn3/db/traits.py (update_sample_data): If a value is "x", delete it from the
respective table.
|
|
When editing values from "x" to "0"(or any other value) when editing data, an
"update" statement was being run; thereby no new value was being inserted. To
the end user, modifying an "x" value to something else meant that no value was
being inserted. This commit fixes that by doing an insert whenever a change
from "x" to "0" is performed.
* gn3/db/traits.py (update_sample_data): Add insert statements whenever an
"update" statement returns a 0 row-count.

The PublishFreeze table isn't necessary in phenotype queries, since
PublishFreeze.Id = InbredSet.Id (for the purposes of identifying traits,
at least)
|
|
In line 91 of gn3/db/traits.py, there was an if statement "if
record[key] else 'x'" that was treating values of 0 as False, so I
changed it to explicitly check that values aren't None
|
|
The PublishFreeeze table is actually unnecessary for this query, since
the group ID (inbred_set_id) should be passed in and that ID is in the
PublishXRef table (so no neeed to join with PublishFreeze)
|
|
Indent the code correctly.
|
|
The queries run in the `get_trait_csv_sample_data` and
`retrieve_publish_trait_data` functions in the `gn3.db.traits` module were
mostly similar. This commit changes that, by making the
`get_trait_csv_sample_data` function make use of the results from calling the
`retrieve_publish_trait_data` function.

* Some traits have a name composed of all numerals, which leads to the names
being interpreted as numbers. This commit forces them to string to avoid
subtle bugs where the code fails.

Issue:

* In an attempt to optimise the performance of the partial correlations
feature, this commit reworks some database access functions to fetch
multiple items from the database, per query, unlike their original forms
which would fetch a single item per query.
This reduces queries to the database, and should hopefully improve the
responsiveness of the partial correlations feature.

The problem with using the "value" record is that it's a floating point
number. See
<https://www.bonfacemunyoki.com/post/2021-10-21-comparing-floating-point-numbers/>
on why comparing floating point numbers can be an issue.

Sometimes, a user will try to insert data twice, on in some instances, 2
different users will attempt the same inserts of the same records separately.
In such cases, ignore the insert, and return early.
|
|
In the case when the user tries to delete the same data twice, prior to this
commit, an error was being generated. This commit remedies this by checking
if a record exists prior to deleting it.

type of return dictionary.

* gn3/db/datasets.py: Import List from typing.
(sparql_query): Set return type to List[Dict[str, Any]].
