Re: Upload a excel table, generate model at run time and save it to database

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:

class Spreadsheet(models.Model):      user = ...      ...      class Cell(models.Model):      spreadsheet = models.ForeignKey(Spreadsheet)      row = models.PositiveIntegerField()      column = models.PositiveIntegerField()      content = models.TextField(blank=True)        class Meta:          unique_together = (spreadsheet, row, column)

I like to create a site where users upload their excel (1 or many) and use the platform to query the data anytime they login.

So can someone help how can i do the below:

1. How can i create a model for any excel table or shapefile at run time and build ORM before saving it to database? Because its not possible to imagine the column names and their data types.

2. Also , like to know a simple strategy of loading those tables in database instead of loading each imported excel table as different table in the database.
