The need string or buffer, int found, and djangobuffer messages are displayed when the added data is saved in django admin.

Cause

Def _ unicode _ (self): return unicode (self. pk)

If unicode is not found, this error is reported because the encoding is incorrect.

It is because the file is not added with UTF-8 at the beginning, but it is still incorrect.

Take a closer look:

The _ unicode _ () method can be processed to return the string representation of an object.
Here is the default value, so if you are not a string, an error will occur. Change it to str () and try again.

It turns out that it is also possible.
