django.db.utils.OperationalError: (1050, "Table 'doc_evlt' already exists")

这个错误通常是因为您的数据库中已经存在了一个名为`doc_evlt`的表，而您的Django应用程序尝试再次创建这个表。解决方法是删除数据库中的`doc_evlt`表，或者在您的Django模型中使用`managed = False`禁用Django自动创建表。您还可以运行Django的`migrate`命令来同步数据库结构，它将检查哪些表已经存在并跳过创建它们。

django.db.utils.operationalerror: (1050, "table 'django_content_type' already exists")

这个错误是因为在数据库中已经存在名为'django_content_type'的表，而Django尝试再次创建该表。需要检查数据库中是否已经存在该表，如果存在，则需要删除该表或更改Django模型以使用现有表。

django.db.utils.OperationalError: (1050, "Table 'tb_address' already exists")

This error message indicates that a table named "tb_address" already exists in the database. This commonly occurs when attempting to migrate a Django application that has already been migrated before, or when manually creating database tables.

To resolve this issue, you can either delete the existing "tb_address" table from the database or modify the migration file to skip the creation of the table.

If you choose to delete the table, you can use the SQL command:

DROP TABLE tb_address;

If you want to modify the migration file, you can add the following line at the beginning of the migration file:

dependencies = [
    ('app_name', 'previous_migration_name'),
]

Replacing "app_name" with the name of your Django application and "previous_migration_name" with the name of the previous migration file. This will tell Django to skip the migration that creates the "tb_address" table.
