I created the models.py file and when I try to execute the 'makemigrations' command, I get the following error:

    return bool(self.related_name) and self.related_name[-1] == '+'

TypeError: 'ModelBase' object does not support indexing

I tried to find a forum reply, but the topics mainly concern the error that appears from the views.py file. In my situations, this file has not been created yet.

Any help will be appreciated, also about the more transparent code in the database.

My models.py

Your ManyToManyField configuration for my_projects is not correct. A ManyToManyField takes a single class as it's first positional argument. It can also accept other optional arguments such as related_name.

You have passed multiple classes as arguments. ManyToManyField would thus assume that these other classes correspond to the values for the optional arguments, causing the error you're seeing.

You would need to separate my_projects into separate ManyToManyFields:

my_photogalleries = models.ManyToManyField(Prem_PhotoGallery)

my_pdfs = models.ManyToManyField(Prem_PDF)

... etc ...
