Question

我在一个简单的django项目中设置了一些模型。我跑的时候

python manage.py sql fivefives

当我运行syncdb或验证我得到0错误时，我得到了很多漂亮的sql。

BEGIN;
CREATE TABLE "fivefives_player" (
    "id" serial NOT NULL PRIMARY KEY,
    "username" varchar(200) NOT NULL,
    "colour" varchar(7) NOT NULL,
    "remaining_dice" integer NOT NULL
)
;
CREATE TABLE "fivefives_game_player_list" (
    "id" serial NOT NULL PRIMARY KEY,
    "game_id" integer NOT NULL,
    "player_id" integer NOT NULL REFERENCES "fivefives_player" ("id") DEFERRABLE INITIALLY DEFERRED,
    UNIQUE ("game_id", "player_id")
)
;
CREATE TABLE "fivefives_game" (
    "id" serial NOT NULL PRIMARY KEY,
    "time" timestamp with time zone NOT NULL
)
;
ALTER TABLE "fivefives_game_player_list" ADD CONSTRAINT "game_id_refs_id_c39af54" FOREIGN KEY ("game_id") REFERENCES "fivefives_game" ("id") DEFERRABLE INITIALLY DEFERRED;
CREATE TABLE "fivefives_round_player_list" (
    "id" serial NOT NULL PRIMARY KEY,
    "round_id" integer NOT NULL,
    "player_id" integer NOT NULL REFERENCES "fivefives_player" ("id") DEFERRABLE INITIALLY DEFERRED,
    UNIQUE ("round_id", "player_id")
)
; ... it continues like this...

但是当我跳进管理员时，表格就不存在了。登录postgres我看到表格甚至都没有创建。

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.postgresql_psycopg2', # Add 'postgresql_psycopg2', 'postgresql', 'mysql', 'sqlite3' or 'oracle'.
        'NAME': 'perudodb',                      # Or path to database file if using sqlite3.
        'USER': 'postgres',                      # Not used with sqlite3.
        'PASSWORD': 'postgres',                  # Not used with sqlite3.
        'HOST': '',                      # Set to empty string for localhost. Not used with sqlite3.
        'PORT': '',                      # Set to empty string for default. Not used with sqlite3.
    }
}

之前有人想出过这样的事吗？只是将所有文件复制到我的朋友计算机上并同步，这一切都很有效。

Answer 1

manage.py sql实际上并不运行SQL，它只是打印它。

Answer 2

要实际创建表格，您需要manage.py syncdb。

Django查询在postgres中消失
