django-ckeditor の画像アップロードでハマったメモ

Django Python

(django1.8, python2.7)

手順

ここ に書いてあるけど...

  1. Add ckeditor_uploader to your INSTALLED_APPS setting
  2. Add CKEDITOR_UPLOAD_PATH = "uploads/" setting
  3. Add (r'^ckeditor/', include('ckeditor_uploader.urls')), project's urls.py
  4. 略
  5. Install pillow and Add CKEDITOR_IMAGE_BACKEND = "pillow" setting

わかりづらかった箇所

models.py

wysiwyg editor 使う field を下記のように変更する

from django.db import models
from ckeditor_uploader.fields import RichTextUploadingField


class Hoge(models.Model):
    contents = RichTextUploadingField(u'内容', blank=True, default='')

forms.py

forms.Textarea(...) ではなく

forms.CharField(widget=CKEditorWidget()),

CharField!

ほか

画像アイコンを押すと アップロード タブが表示されてアップできるようになる。

Golangのコマンドラインツールパッケージ urfave/cli を使って御神籤を作ってみるメモ

Golang

code

package main

import (
    "fmt"
    "math/rand"
    "os"
    "time"

    "github.com/urfave/cli"
)

func suffle(arr []string) {
    rand.Seed(time.Now().UnixNano())
    n := len(arr)
    for i := n - 1; i > 0; i-- {
        j := rand.Intn(i + 1)
        arr[i], arr[j] = arr[j], arr[i]
    }
}

func main() {
    app := cli.NewApp()
    app.Name = "omikuji"
    app.Usage = "Get today's fortune!"
    app.Version = "0.1"

    app.Flags = []cli.Flag{
        cli.StringFlag{
            Name:  "level",
            Value: "normal",
            Usage: "Fortune level, it is hard, easy and normal",
        },
    }

    app.Action = func(c *cli.Context) error {
        fortunes := []string{
            "Dai-kichi",
            "Kichi",
            "Chu-kichi",

            "Shou-kyou",
            "Dai-kyou",
        }

        if c.String("level") == "hard" {
            fortunes = []string{
                "Dai-kichi",
                "Dai-kyou",
            }
        } else if c.String("level") == "easy" {

            }
        }
