            Your problem has nothing to do with how you are registering your global settings -- setting config.Formatters.JsonFormatter.SerializerSettings.ContractResolver is correct as per this question. Your problem is that Json.NET does not call ResolvePropertyName() when the contract resolver also has a NamingStrategy -- and your base class CamelCasePropertyNamesContractResolver does indeed have a naming strategy.

            This can be verified by checking the current Json.NET reference source for DefaultContractResolver.SetPropertySettingsFromAttributes():

            Try logging the SQL query, instead of the values. This should help you see what you're actually telling the DBMS to do. You may find that you're sending it the wrong values.

            Also, instead of a couple of numerical for loops, try this:

            How to JSON serialize a python built-in class (eg. int)?

            I need to serialize a tuple that contains a raw python datatype or in other words a built in class eg. int/str. But the json library throws an error like TypeError: Object of type type is not JSON serializable

            ANSWER

            Answered 2020-Apr-10 at 22:31

            There is no way to serialize a JSON or Python type as JSON value. As described in RFC7159 Section 3 the only available values are:

            false / null / true / object / array / number / string

            However you could serialize a Python type as a JSON string. For instance, a Python int would become JSON string value "int".

            Since Python keyword int is object of type type. You can use __name__ to get its string name. For instance: print(int.__name__).

            To automatically encode it, I let you check this answer which use a custom JSONEncoder.

            what are actual formulas for glOrtho
            Asked 2020-Jan-31 at 22:26

            Working with legacy project that used OpenGL and adapting it to OpenGL ES I stumbled upon this problem. I have to implement matrix stack use on my own and create some state machine and own implementation of glOrtho and glPerspective, but some documentation are different, depending on which source I look.

            Documentation on Kronos website is mangled and unusable. Documentation on Microsoft site

            Another version, which matches also formulas in man pages and some books:

            Experimentation with glGelFloatv() had shown that on Windows glOrtho() uses first version. Is it possible that other platforms use another? There were plenty problems with projection matrix in this code base and trying swapping out implementation aggravated either one or another, to the point that I get impression that sign actually changes under some conditions. Which variant I should to follow? Does glOrtho contain some additional logic aside from multiplying existing matrix on new one?

            The only truth is the specification. From OpenGL 2.1 API specification - 2.11.2 Matrices:

            void Ortho( double l, double r, double b, double t, double n, double f );

            describes a matrix that produces parallel projection. (l b − n)T and (r t − n)T specify the points on the near clipping plane that are mapped to the lower left and upper right corners of the window, respectively. f gives the distance from the eye to the far clipping plane. If l is equal to r, b is equal to t, or n is equal to f, the error INVALID VALUE results. The corresponding matrix is

            To start with, your query has a logical flaw. ORed conditions should be surrounded with parentheses.

            Then: you could use IN instead of OR. This might improve performance.

            I also suspect that you want records for the whole month of November, in which case BETWEEN ... AND to_date('30-NOV-19' ,'DD-MON-YY') does not do exactly what you want, since it would evict dates between November 30th at 00:00:01 and 23:59:59.

            Also, I would recommend using date litterals instead of TO_DATE(). This is the proper way to handle date constants.

            I would express your query as:

            After a successful upgrade from Django 1.8 to Django 2.2.4, when I run the tests it fails because Django does not create the database tables.

            My test_settings.py file was working appropriately before the upgrade.

            after debugging the Django db/backends it looks like the connection was created, but the tables were not. my suspicion is that test_setting.py is not configured well, although I copied everything from the setting.py file except the database configuration (that remained SQLite).

            Somewhere along the line it became required for the databases used by test cases to be attached to them. Before instantiating the test database, Django makes a list of all the databases which will be required based upon the objects. After this it makes the schemas for them.
