Answer 1

<强> forms.py

from django import forms
from app.models import *

class HomeForm(forms.Form , forms.ModelForm):
  tweet = forms.CharField(max_length = 280 ,widget = forms.Textarea)
  image = forms.ImageField(label='Select a Image file',)

<强> views.py

from django.shortcuts import render
from django.views.generic import TemplateView
from TwitterAPI import *
from app.forms import *
class Texting(TemplateView):        
   def post(self, request):
      form = HomeForm(request.POST,request.FILES)
      if form.is_valid():
        text = form.cleaned_data['tweet']
        image = form.cleaned_data['image']

Answer 2

<template> <div> <md-app> <jg-header></jg-header> </md-app> </div> </template>已弃用。此API调用已由两步过程替换。首先，使用statuses/update_with_media上传图片。其次，使用media/upload使用媒体ID发布您的推文。您可以在https://github.com/geduldig/TwitterAPI/blob/master/examples/update_media.py找到完整的示例。

statuses/update
