#23 Object has no attribute 'export'

[Mustafa Şenol Coşar]

Hi Dave,

I used the latest version of generateDS (v2.40.1) and there seems to be a problem.
The generated code has __str__ method in the GeneratedsSuper class. This is new since the version 2.36.2
The problem is with the following:

    def __str__(self):
        ...
        from io import StringIO
        output = StringIO()
        self.export(
            output,
            settings['str_indent_level'],
            pretty_print=settings['str_pretty_print'],
            namespaceprefix_=settings['str_namespaceprefix'],
            name_=settings['str_name'],
            namespacedef_=settings['str_namespacedefs']
        )
        strval = output.getvalue()
        output.close()
        return strval

The self.export method does not exist because it is commented out. It gets commented out because in the template those lines are prefixed by #xmldisable# and we are using --disable-xml flag.

Mustafa,

Oops.

OK, so I've "disabled" generation of that __str__ method. Actually, it's generated, but is commented out. That method is intended as a convenience for a programmer who wants to display an object while debugging. Am I right that you can do without it?

With the new code and when using --disable-xml, when you ask for a string representation, you will see:

[ins] In [21]: import tmp04sup as lib4
[ins] In [22]: b = lib4.containerType()
[ins] In [23]: print(str(b))
<tmp04sup.containerType object at 0x7fd5b2651130>

Attached is a patch file.

I did some checking. But, I'm a little unsure about possible dependencies in that code. Could you try this patch and let me know. If all is well with it and you do not need that __str__ method, I'll create a new release.

Hi Dave, the patch works for me.

Although having string representation could be nice. Something like the following when xml is not enabled:
Class1(field1=value1, field2=value2, field3=Class2(field4=value4))

However, it is not critical right now.

Mustafa,

Uploaded the fix for __str__ and export with --disable-xml.

It's version 2.40.2.

Thanks for the help with this.

Mustafa,

I introduced a bug. I got the indentation of __str__ wrong.

It is fixed in version 2.40.3.

I apologize. Hope I got it right this time.

I'll look into your suggestion for the improved __str__ method, next week.

Dave
