Kesalahan ini terjadi ketika Django==2.0, saat ini Bootcamp tidak kompatibel dengan versi Django itu. Silakan hapus dan instal versi sebelumnya, django==1.11.x bekerja dengan benar.

Selamat pagi @sebastian-code ,

Saya telah menurunkan Django, tetapi sekarang saya memiliki kesalahan ini:

Hai @Allan-Nava tampaknya Anda memiliki masalah dengan database Anda dan server tidak dapat membuat koneksi dengan volume data, bagaimana Anda melakukan bagian itu?

sebastian-code picture sebastian-code pada 20 Des 2017

Hai @sebastian-code, adalah aplikasi django pertama saya dengan windows pc pribadi saya. Apa yang harus saya lakukan?

Allan-Nava picture Allan-Nava pada 20 Des 2017

Itu tergantung bagaimana Anda bekerja dengan database. Secara pribadi saya menggunakan Docker, tetapi Anda dapat menggunakan instance lokal PostgreSQL, mungkin memasang server DB jaringan, atau semacam VM. Ada juga opsi yang lebih mudah daripada menggunakan SQLite secara lokal.

Saya ingin mencoba menggunakan SQLite Lokal

Allan-Nava picture Allan-Nava pada 20 Des 2017

Untuk itu mendefinisikan DATABASE_URL variabel di dalam Anda .env file dengan alamat database yang SQLite Format benar dengan menggunakan format URL. Anda dapat menemukan contoh di dalam file env.example .

sebastian-code picture sebastian-code pada 20 Des 2017

Saya menggunakan .env dengan conf yang sama:

# PostgreSQL conf
# POSTGRES_PASSWORD=mysecretpass
# POSTGRES_USER=my_super_user
# POSTGRES_DB=bootcamp
# DATABASE_URL=postgresql://my_super_user:[email protected]:5432/bootcamp

# Main environmental variables
DEBUG=True
SECRET_KEY=s3cr3t_key
ALLOWED_HOSTS=*
# URL to have SQLite example and to pass TravisCI
DATABASE_URL=sqlite:////bootcamp/db.sqlite3
# URL for Redis
# REDIS_URL=redis://redis_ip_address:port

Saya mempunyai kesalahan yang sama:

Itu karena alamatnya salah jalan. Untuk SQLite, Django memerlukan lokasi fisik untuk file SQLite di dalam hard drive Anda, dinyatakan dalam format URI.

@ sebastian-code Saya punya Django 2.x di pip cache. Sekarang bagaimana saya bisa memaksa pip untuk menggunakan Django 1.9 saat menjalankan perintah ini pip install -U -r requirements/local.txt

jackengine picture jackengine pada 12 Jan 2018

Hai @jackengine Cara termudah adalah dengan menjalankan perintah, dan setelah diinstal, hapus paket secara manual, dan kemudian instal Django lagi, tetapi mendeklarasikan versi tertentu yang Anda inginkan. Saran saya tidak akan pergi dengan Django v1.9, terlalu tua, saya akan menyarankan untuk menggunakan Django 1.11 yang LTS.
