Sending a Dictionary to a HTML Template and displaying it using Flask.
This post shows explains sending a dictionary to a HTML template from a Python Server and the data is displayed by running a loop.
Python Code for a single object
from flask import Flask,render_template,request
app=Flask(__name__)
class Product:
def __init__(self,productname,productquantity,productprice):
self.productname=productname
self.productquantity=productquantity
self.productprice=productprice
def __str__(self):
return "Name = {0}, quantity={1}, Price = {2}".format(self.productname,self.productquantity,self.productprice)
d={1:Product("Pepsi",10,15)}
@app.route("/")
def index():
p1=d.get(1)
return render_template("products.html",name1=p1.productname,quantity1=p1.productquantity,price1=p1.productprice)
if __name__ == "__main__":
app.run(host="localhost", port=int("777"))
Template
<!DOCTYPE html>
<html>
<head>
<title>Products</title>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
</head>
<body>
<div>
<center>
<table width="100%" border="1">
<tr><td>Name</td><td>Quantity</td><td>Price</td></tr>
<tr><td>{{name1}}</td><td>{{quantity1}}</td><td>{{price1}}</td></tr>
</table>
</center>
</div>
</body>
</html>
Sending a Dictionary to a Template.
</pre>
from flask import Flask,render_template
#app = Flask(__name__)
app = Flask(__name__, static_url_path='/static')
d={2:"Mumbai",1:"Jaipur",3:"Varanasi"}
@app.route("/")
def index():
return render_template('dict.html',dict=d)
if __name__ == "__main__":
#print(__name__)
app.run(host="localhost", port=int("777"))
#app.run()
<pre>
Template
</pre>
<!DOCTYPE html>
<html>
<head>
<title>Products</title>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
</head>
<body>
<div>
<center>
{{dict}}
</center>
{% for key, value in dict.items() %}
<h1>Key: {{key}}</h1>
<h2>Value: {{value}}</h2>
{% endfor %}
{% for key in dict.keys()%}
{% set value=dict.get(key)%}
<h1>Key: {{key}}</h1>
<h2>Value: {{dict.get(key)}} {{value}}</h2>
{% endfor %}
</div>
</body>
</html>
<pre>
Combine these two and make a template that displays a dictionary of Product objects.
