One should have control over the order of children. Currently they are ordered in exportChildren by their Generateds class.
This is important, for example, for math prefix notation where / 1 2 is not the same as / 2 1.

Hi, hope you can help me here.

I have some .xsd files where im trying to convert them to sql.

Do you know if it will be possible to do so leveraging the generateDS package?

Thank you,
Eliano

I would like to use the python script gends_generate_django.py from the generateDS toolbox to generate Django models from an initial XSD file.

According to the documentation (point 16.1) I would like to go through the following three steps:

1. Generate bindings -- Run generateDS.py.
2. ExtractsimpleType definitions from schema -- Run gends_extract_simple_types.py.
3. Generate models.py and forms.py -- Run gends_generate_django.py.

Steps 1+2 could be completed successfully. In step 3 the following error message appears:

Traceback (most recent call last):

ModuleNotFoundError: No module named 'SOME_PATH/generateds_definedsimpletypes'

Where generateds_definedsimpletypes.py is the output from running gends_extract_simple_types.py.

I have tried running the script both in the Conda environment and underself-installed Python. Moreover, I have used generateDS version 2.40.12. and Python 3.9.13.

What is my mistake when executing the script?

Many thanks for your replies!

When creating an element whose attribute is an enumeration in XSD, the element factory receives a string instead of an enumeration. It makes it necessary to explicit the enumeration value in order to properly export an .XML file.

For example, for the following generated enumeration:

class ProtectionActuation(Enum):
    PIOC='PIOC'
    PTOC='PTOC'
    RBRF='RBRF'
    PTUC='PTUC'

and the instanciation of an hypothetical element that has that enumeration attribute:
event= PSREvents.factory(name = ProtectionActuation.PIOC)

the exported XML file is mapped as:

        <PSREvents>
            <name>ProtectionActuation.PIOC</name>
        </PSREvents>

instead of:

        <PSREvents>
            <name>PIOC</name>
        </PSREvents>

(Although it could be easily fixed by expliciting its value:
event= PSREvents.factory(name = ProtectionActuation.PIOC.value)
)

So, the code generated looks like this:

    def validate_ISONormalisedDateTime(self, value):
        result = True
        # Validate type ISONormalisedDateTime, a restriction on xs:dateTime.
        if value is not None and Validate_simpletypes_ and self.gds_collector_ is not None:
            if not isinstance(value, datetime_.datetime):
                lineno = self.gds_get_node_lineno_()
                self.gds_collector_.add_message('Value "%(value)s"%(lineno)s is not of the correct base simple type (datetime_.datetime)' % {"value": value, "lineno": lineno, })
                return False
            if not self.gds_validate_simple_patterns(
                    self.validate_ISONormalisedDateTime_patterns_, value):
                self.gds_collector_.add_message('Value "%s" does not match xsd pattern restrictions: %s' % (encode_str_2_3(value), self.validate_ISONormalisedDateTime_patterns_, ))
                result = False
        return result

The value here is an datetime object type. Not a String, so the second if block is not working as expected.

gds_validate_simple_patterns(self.validate_ISONormalisedDateTime_patterns_, value)

Should validate the date pattern to a string not a datetime value.

I've fixed the generated code adding the sval of the Element to the validation and calling the regular expression validation with it.
