[PYTHON] Ihr eigener Twitter-Client mit Django
Ich werde versuchen, es zu schaffen
Wie bei der Flasche denke ich, dass sich das Grundverständnis von Django vertiefen wird, wenn Sie mit der Erstellung eines Twitter-Clients beginnen. Übrigens werde ich etwas erstellen, mit dem Sie Beiträge, Antworten und Home-Timelines auf einem Bildschirm anzeigen können.
Das Ergebnis ist ein solches Bild.
- API-Limit-Anzeige
- Zeigen Sie eine Zeitleiste an
- Bereiten Sie die Antwort vor, indem Sie auf den Benutzernamen oder das Bild in der Zeitleiste klicken
- Sie können Text twittern
Es wird eine Spezifikation wie sein.
Wenn Sie es unter ähnlichen Bedingungen ausprobieren möchten, lesen Sie bitte den vorherigen Artikel. http://qiita.com/Gen6/items/735245423b65698428be

Wenn Sie es in der Datenbank speichern möchten, lesen Sie bitte den folgenden Artikel. http://qiita.com/Gen6/items/907d869cdf1d588a4751
Weitere Anpassung
Erstellen Sie mit einem Bild wie oben.
Überprüfen Sie settings.py
Ich werde um Zeile 107 schreiben.
mysite/settings.py
LANGUAGE_CODE = 'ja'
TIME_ZONE = 'Asia/Tokyo'
USE_I18N = True
USE_L10N = True
USE_TZ = True
STATIC_URL = '/static/'
STATICFILES_DIRS = (
os.path.join(BASE_DIR, "static"),
)
Fügen Sie views.py hinzu
Es ist ein Muster, das das Posten, Erwähnen und Suchen implementiert. Da es in einer Ansichtsdatei geschrieben ist, ist es nicht einfach zu pflegen, aber beziehen Sie sich bitte darauf.
Sie können den SCHLÜSSEL nach draußen legen oder einfacher schreiben, aber er ist leicht zu verstehen. Probieren Sie verschiedene Dinge aus, um Ihren Code sauber zu halten.
Die Suchergebnisse sind ein in der Datenbank gespeichertes Muster.

data.user_id = User
data.user_name = Name
data.user_img = Img
data.user_text = Text
data.user_created_at = Created_at
data.save()

Schreiben Sie urls.py
myapp/urls.py
from django.conf.urls import url
from . import views
urlpatterns = [
url(r'^$', views.index, name='index'),
url(r'^search/', views.search, name='search'),
url(r'^mentions/', views.mentions, name='mentions'),
]
Schreiben Sie models.py und admin.py
Wenn Sie die Tweet-Suchergebnisse nicht in der Datenbank speichern, benötigen Sie Folgendes nicht, sondern nur für den Fall, dass es in views.py beschrieben wird. Da SQLITE verwendet wird, belassen Sie die Grundeinstellungen.py als Standard.
myapp/models.py
from django.db import models
class Supermodel(models.Model):
user_name = models.CharField(max_length=140)
user_id = models.CharField(max_length=140)
user_img = models.CharField(max_length=140)
user_text = models.TextField(null=True)
user_created_at = models.CharField(max_length=140)
def __str__(self):
return self.user_name
myapp/admin.py
from django.contrib import admin
from myapp.models import Supermodel
class SupermodelAdmin(admin.ModelAdmin):
list_display = ('id','user_id','user_name','user_img','user_text','user_created_at')
admin.site.register(Supermodel,SupermodelAdmin)
Endgültige Konfiguration
Es sieht aus wie das.
Danach migrieren Sie bitte den Server und führen ihn aus.
