 from bson import ObjectId
 from pymongo import MongoClient
 import os

 app = Flask(__name__)

 client = MongoClient("mongodb://127.0.0.1:27017") #host uri
 db = client.Student #Select the database
 todos = db.Student_list #Select the collection name


 def redirect_url():  
     return url_for('action') 

 @app.route("/list")  
 def lists ():  
   return render_template('snap17.html') 


@app.route("/snap17", methods=['GET','POST'])  
def action ():  
  #Adding a Task  
  name=request.values.get("firstname")  
  todos.insert({ "name":name})

In your view function for /list . Read your datas from databse and accordingly render it in your template like below:

@app.route("/list")  
def lists(): 
    todolist = db.Student_list.find()
    return render_template('snap17.html', todolist=todolist)

And In your template snap17.html render it as

<html>
  {% for elem in todolist %}
     <li> {{elem['name']}}</li>
  {% endfor %}
</html>

And to write into your database make a GET request like this in your existing apllication:

http://localhost:5000/snap17?firstname="JaiSambhu"
