Django fixture fails, stating “DatabaseError: value too long for type character varying(50)”

Question

I have a fixture (json) which loads in development environment but fails to do so in server environment. The error says: \"DatabaseError: value too long for type chara

Answer 1

As @stevejalim says, it's quite possible that the column auth_permission.name is the problem with length 50, you verify this with \d+ auth_permission in postgres's shell. In my case this is the problema, thus when I load django models's fixtures I got “DatabaseError: value too long for type character varying(50)”, then change django.contrib.auth's Permission model is complicated, so ... the simple solution was perform a migrate on Permission model, I did this running ALTER TABLE auth_permission ALTER COLUMN name TYPE VARCHAR(100); command in postgres's shell, this works for me.
