Description Lari Taskula 2016-08-01 07:19:39 UTC
Currently some data types are oddly defined in Swagger. For example borrowernumber is defined as a string, even though it and many other *numbers should be integers/numbers.

Bug 17008: Add "swaggerize" for Koha::Object and Koha::Objects

This patch adds new subroutine "swaggerize" for Koha::Object and Koha::Objects.

By matching column data types with corresponding Swagger data type, we can e.g.
numify values in order to be able to return borrowernumber:123 instead of
borrowernumber:"123".

Before this patch, we usually returned an unblessed representation of the
Koha-object in controller by calling e.g.
  $c->$cb($patron->unblessed, 200);

This would cause the returned JSON to have { "borrowernumber": "123" ... }, or
in other words everything as strings (apart from undefs, which would be null).

Now, we also return an unblessed representation of the Koha-object, but where
numbers are actually numified simply by calling e.g.
  $c->$cb($patron->swaggerize, 200);

Here our returned JSON will have { "borrowernumber": 123 ... } in "integer" data
type of Swagger, as well as every other column that is defined to be an integer.
Decimals, doubles and floats should have "number" data type and will also be
numified for the returned JSON.

To test:
1. Apply this patch and run t/db_dependent/Koha/Util/Swagger.t
2. Apply REST of the patches and follow their test plan for seeing how this
   works in practice

Bug 17008: Fix current data types

This patch changes current Swagger definitions for patrons and holds to have
data types corresponding to column data types in their database tables.

To test:
1. GET http://yourlibrary/api/v1/patrons/YYY where YYY is existing borrowernumber
2. Observe that numbers / integers are in string data type.
3. Apply this patch.
4. Repeat step 1.
5. Observe that numbers / integers are now actually numbers / integers.

Bug 17008: Test to compare Swagger property types against column data types

This patch adds a test that iterates through each definition-object in Swagger
and compares their properties' data types to corresponding Koha-object's column's
data type by using Koha::Util::Swagger::column_type_to_swagger_type().

This test will also check if the column is nullable and will complain
unless property has also "null" defined in its type.

To test:
1. Run t/db_dependent/api/v1/swagger/definitions.t
2. Observe that tests pass (if not, open a Bug to fix issues)
3. Modify api/v1/definitions/patron.json cardnumber to be type "integer".
4. Run the test again.
5. Observe that test fails and will complain about incorrect data type.

Bug 17008: followup - fix cityid type
Comment 24 Tomás Cohen Arazi 2017-01-17 18:04:10 UTC
I'm failing this one:

- Fixing data types and providing and extension for Koha::Object to handle some inconsistencies are different concerns. And bug 17926 provides a more simple way of doing it.
- If you still feel we need to make Koha::Object handle data transformations suitable for output on the REST api, please file a new bug. We still need to openly discuss two things: mistakes in our DB model, and the fact that user facing REST apis don't need to be tied to the underlying model.
- Many of the type fixes are correct, but we need to make booleans be booleans, and this patch fails to do so, making them integers.

I still think we could make use of the column-to-swagger table, but I'm not sure how to deal with Booleans (which are wrongly mapped to integers currently in most of the cases, as there are only a dozen cases in which they are really integers).

I'm open to discuss this on separate bugs that don't catch-them-all. So I'm closing this one, and available to help resurrect the ideas behind this bug.
