If you save the living environment, the biodiversity that we have left,
you will also automatically save the physical environment, too. But If
you only save the physical environment, you will ultimately lose both.
1) Don’t drive species to extinction
2) Don’t destroy a habitat that species rely on.
3) Don’t change the climate in ways that will result in the above.
Although it may be possible, you are not supposed to be creating
models on the fly. This isn't peculiar to Django; it violates the
good practices of relational database systems. You may be able to
accomplish what you want with something like this:
user = ...
spreadsheet = models.ForeignKey(Spreadsheet)
row = models.PositiveIntegerField()
column = models.PositiveIntegerField()
content = models.TextField(blank=True)
unique_together = (spreadsheet, row, column)
