def post_list(request):
posts = Post.objects.all()
return render(request, 'blog/post_list.html', {'posts': posts})
# Flask Task Manager: Basic route to get tasks
from flask import Flask, jsonify
app = Flask(__name__)
tasks = [
{'id': 1, 'title': 'Do the laundry'},
{'id': 2, 'title': 'Write Python code'}
]
@app.route('/tasks', methods=['GET'])
def get_tasks():
return jsonify(tasks)
if __name__ == '__main__':
app.run(debug=True)
