在 Django 中創(chuàng)建項(xiàng)目
在處于活動(dòng)的虛擬環(huán)境下（ll_env包含在括號(hào)內(nèi)），執(zhí)行如下命令來(lái)新建一個(gè)項(xiàng)目：
(ll_env) c5220056@GMPTIC:~/myworkplace$ django-admin.py startproject learning_log .
(ll_env) c5220056@GMPTIC:~/myworkplace$ ls
learning_log ll_env manage.py
(ll_env) c5220056@GMPTIC:~/myworkplace$ ls learning_log/
__init__.py settings.py urls.py wsgi.py
注： 命令末尾的句點(diǎn)讓新項(xiàng)目使用合適的目錄結(jié)構(gòu)唯蝶，這樣開發(fā)完成后可輕松地將應(yīng)用程序部署到服務(wù)器胆萧。
目錄 learning_log 下文件的作用：
- settings.py: 指定 Django 如何與你的系統(tǒng)交互以及如何管理項(xiàng)目鞍历。 在開發(fā)項(xiàng)目過程中，我們將修改其中一些設(shè)置澎怒，并添加一些設(shè)置。
- urls.py: 告訴 Django應(yīng)創(chuàng)建哪些網(wǎng)頁(yè)來(lái)響應(yīng)瀏覽器請(qǐng)求。
- wsgi.py: 是 web server gateway interface（Web服務(wù)器網(wǎng)關(guān)接口）的首字母縮寫谱俭， 幫助 Django 提供它創(chuàng)建的文件。
創(chuàng)建數(shù)據(jù)庫(kù)
(ll_env) c5220056@GMPTIC:~/myworkplace$ python manage.py migrate

db.sqlite3 learning_log ll_env manage.py
首次執(zhí)行命令 migrate 時(shí)宵蛀，將讓 Django 確保數(shù)據(jù)庫(kù)與項(xiàng)目的當(dāng)前狀態(tài)匹配昆著。 在使用 SQLite 的新項(xiàng)目中首次執(zhí)行這個(gè)命令時(shí)，Django將新建一個(gè)數(shù)據(jù)庫(kù)术陶。Django 指出它將創(chuàng)建必要的數(shù)據(jù)庫(kù)表凑懂， 用于存儲(chǔ)我們將在這個(gè)項(xiàng)目（Synchronize unmigrated apps, 同步未遷移的應(yīng)用程序）中使用的信息，再確保數(shù)據(jù)庫(kù)結(jié)構(gòu)與當(dāng)前代碼（Apply all migrations梧宫， 應(yīng)用所有的遷移）匹配接谨。
SQLite是一種使用單個(gè)文件的數(shù)據(jù)庫(kù)。
