python - 在django中设置数据库

Question

我遵循了 django 文档并完成了民意测验示例。我有一个 sqlite 数据库 'nameinfodb'。我想通过在线搜索姓氏来访问它。我将 models.py 设置为

class Infotable(models.Model):
    pid_text = models.CharField(max_length=200)
    lname_text = models.CharField(max_length=200)
    fname_text = models.CharField(max_length=200)
    affs_text = models.CharField(max_length=2000)
    idlist_text = models.CharField(max_length=2000)
    def __str__(self):
        return self

我复制了name.info.db到db.sqlite3所在的地方，修改了settings.py:

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.sqlite3',
        'NAME': os.path.join(BASE_DIR, 'name.info.db'),
    }
}

然后我跑

python manage.py migrate  
python manage.py makemigrations pidb

然后我检查我是否做对了

$ python manage.py sqlmigrate pidb 0001

BEGIN;
--
-- Create model Choice
--
CREATE TABLE "pidb_choice" ("id" integer NOT NULL PRIMARY KEY AUTOINCREMENT, "choice_text" varchar(200) NOT NULL, "votes" integer NOT NULL);
--
-- Create model Question
--
CREATE TABLE "pidb_question" ("id" integer NOT NULL PRIMARY KEY AUTOINCREMENT, "question_text" varchar(200) NOT NULL, "pub_date" datetime NOT NULL);
--
-- Add field question to choice
--
ALTER TABLE "pidb_choice" RENAME TO "pidb_choice__old";
CREATE TABLE "pidb_choice" ("id" integer NOT NULL PRIMARY KEY AUTOINCREMENT, "choice_text" varchar(200) NOT NULL, "votes" integer NOT NULL, "question_id" integer NOT NULL REFERENCES "pidb_question" ("id"));
INSERT INTO "pidb_choice" ("id", "question_id", "choice_text", "votes") SELECT "id", NULL, "choice_text", "votes" FROM "pidb_choice__old";
DROP TABLE "pidb_choice__old";
CREATE INDEX "pidb_choice_7aa0f6ee" ON "pidb_choice" ("question_id");

COMMIT;

我没有看到有关新数据库的任何信息，我看到的只是示例民意调查数据。我在这里做错了什么吗？我需要做的就是连接到 name.info.db，并通过姓氏访问它。谢谢!

你需要反过来做:

python manage.py makemigrations pidb
python manage.py migrate
