So I've been looking at this for over an hour and I cannot figure out what the heck is going on.
The script is printing only a ">"
It's suppose to print the full HTML and then, after the form is submitted, print "print_after"

radio = self.request.GET['trade']
self.response.write(p.print_after(name, age, time, model, radio))
print name + age + time + model + radio
else:
self.response.write(p.print_one)

I tested your code and rearranged it a little. I used http post for submitting the form and then it prints the form variables.

The above code starts a local webserver at port 8080. It might not do exactly what you want, but much is there. You can also run it in appengine.

i'm learning Flask/Ajax.
In a POST method i read some data from pwstest.html to run a python script.
Following the Python
#wApp.route("/pwstest",methods=\['GET','POST'\])
def index():
titlepage ='Page title
stato=''
args, data, method = fjrh.handleRequest(request,auth=False)`
if method =='POST':
stato = ''
output = request.get_json()
result = json.loads(output)
logging.info(result)
utente = result\['testoinput'\]
identificativo = result\['numeroinput'\]
dataestrazione = result\['datainput'\]
format='%Y-%m-%d'
dataestrdate = datetime.strptime(dataestrazione,format)
datastr= dataestrdate.strftime("%d-%m-%Y")
parziale= result\['datacheck'\]
if parziale == 'on':`
stringpws = 'http://192.168.x.xxx:5009/plan?diff=True&data=' + datastr
else:

Thank you in advance.
I am writing a Django website for dentists, the dentist can register patients with form easily not an issue, however when registering visits for a patient it is not saved, in the admin panel both models works just fine, on the website the visits form dose not save to database.

If the form is not valid, it wont be committed to database.
Print the form errors, this should help you understand why the form is not getting saved
if form.is_valid():
form.save()
else:
print(form.errors)
I think you didn't provide context in view:
Instead of this:
def addVisit(request):
if request.method == 'POST':
form = VisitForm(request.POST or None)
if form.is_valid():
form.save()
return render(request, 'addVisit.html', {})
else:
return render(request, 'addVisit.html', {})
try this:
def addvisit(request):
if request.method == 'POST':
form = VisitForm(request.POST)
if form.is_valid():
try:
form.save()
return redirect("/") #Add your project route here where you want to go after adding visitors
except:
pass
else:
form = VisitForm()
return render(request, 'addvisit.html', {'form':form})
hi I created a simple website to calculate the square of the number. below is the code
calculate.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1.0">

<body>
<header>
square
</header>
<div class="congrat">
{{ result }}
</div>
</body>
</html>
homepage.html
<form method="post" action="/square">
<div class="calculate">
<b>Square</b><br/>Num
<input type="text" name="number"><br/>
<input type="submit" value="calculate">
</div>
</form>
python
#app.route("/square", methods=['POST'])
def square():
number = request.form["number"]
return render_template("calculate.html", result = int(number) ** 2)
now I want to display input number in URL path. e.g. http://127.0.0.1:3000/square/10
so I've tried this
<form method="post" action="/square/<number>">
<div class="calculate">
<b>Square</b><br/>Num
<input type="text" name="number"><br/>
<input type="submit" value="calculate">
</div>
</form>
#app.route("/square/<number>", methods=['POST'])
def square(number):
number = request.form["number"]
return render_template("calculate.html", result = int(number) ** 2)
but it didn't work. What could I do?
You could get variables directly parsed from Flask URL
#app.route("/square/<number>", methods=['POST'])
def square(number):
return render_template("calculate.html", result = int(number) ** 2)
Edit:
<form id="your_form" method="post" onsubmit="yourFunction()">
<input type="text" name="keywords">
<input type="text" name="number"><br/>
<input type="submit" value="calculate">
</form>
<script>
function yourFunction(){
var action_src = "/square/" + document.getElementsByName("number")[0].value;
var your_form = document.getElementById('your_form');
your_form.action = action_src ;
}
</script>
I'm trying to build a website that generates a power hour style video from a list of music videos that the user selects by searching through the youtube api. I'm having trouble figuring out how to append selected videos to a list (addedVideos) in view.py from a button (add) in my html. I need to append each added video to a list so I can display them and loop through them in an embedded youtube player. This is my first django project so I don't have a good understanding of what the potential problems could be. index.html and views.py below:
views.py
import requests
from isodate import parse_duration
from django.conf import settings
from django.shortcuts import render, redirect
def index(request):
addedVideos = []
videos = []
if request.method == 'POST':
search_url = 'https://www.googleapis.com/youtube/v3/search'
video_url = 'https://www.googleapis.com/youtube/v3/videos'
search_params = {
'part' : 'snippet',
'q' : request.POST['search'],
'key' : settings.YOUTUBE_DATA_API_KEY,
'maxResults' : 3,
'type' : 'video'
}
#print(request.POST['submit'])
r = requests.get(search_url, params=search_params)
#print(r)
results = r.json()['items']
#print(results)
video_ids = []
for result in results:
video_ids.append(result['id']['videoId'])
if request.POST['submit'] == 'lucky':
return redirect(f'https://www.youtube.com/watch?v={ video_ids[0] }')
video_params = {
'key' : settings.YOUTUBE_DATA_API_KEY,
'part' : 'snippet,contentDetails',
'id' : ','.join(video_ids),
'maxResults' : 3
}
r = requests.get(video_url, params=video_params)
results = r.json()['items']
for result in results:
video_data = {
'title' : result['snippet']['title'],
'id' : result['id'],
'url' : f'https://www.youtube.com/watch?v={ result["id"] }',
'duration' : int(parse_duration(result['contentDetails']['duration']).total_seconds() // 60),
'thumbnail' : result['snippet']['thumbnails']['high']['url']
}
videos.append(video_data)
if request.POST['add'] == 'addValue':
print("add clicked")
context = {
'videos' : videos,
'addedVideos': addedVideos
}
return render(request, 'search/index.html', context)

Running this as is gives a MultiValueDictKeyError at 'q' : request.POST['search'],
Any help would be appreciated, thanks.
You should put / in front of search/index.html instead of search/index.html.
And you don't have to have the https:// you can just put // instead.
i'm creating a python web application which get multiple user input from input type="number" and calculation will be done when input type="submit" is pressed. I managed to do it but it appears that input that user entered earlier disappear because the page refresh when submitted. Can anyone help me how to keep the user input even after input type="submit" is pressed.
This is my python script:
from flask import Flask, render_template, request
import math
app = Flask(__name__, template_folder='C:\\Users\\iyzadsyammil\\.PyCharmCE2017.1\\config\\fileTemplates')
#app.route('/')
def index():
return render_template('index.html')
#app.route('/Menu')
def showmenu():
return render_template('index.html')
#app.route('/App',methods=['GET', 'POST'])
def showapp():
outpb=0
x=0
logpb=0

No jQuery, no Ajax. but obviously you need some JS.
<input id="number" type="number" value="num">
<input id="submit" type="submit" value="submit">
document.getElementById("submit").addEventListener("click", function(){
var val = document.getElementById("number").value
sessionStorage.setItem("number", val);
});
window.onload = function() {
var session_value = sessionStorage.getItem("number") || 0;
document.getElementById("number").value = session_value;
}
If you give some clues that how do you use python (db interaction, templating etc.) another solutions might be considered.
sessionStorage
The <input type="submit"> will reach the action attribute of your <form> when clicked, or will refresh the page if the action is empty.
You can use a <button> element and assign it a function on the click event, for example:
<!-- There is no form needed if you don't need to submit -->
<div id="form">
<input type="number" id="myNumber">
<input type="number" id="myOtherNumber">
<button type="button" id="submit">Calculation</button>
</div>
JS part:
window.onload = function () {
/* get elements */
var num_1 = document.getElementById('myNumber'),
num_2 = document.getElementById('myOtherNumber'),
btn = document.getElementById('submit');
/* do what you want with your number
when the button is clicked */
btn.onclick = function () {
window.console.log(num_1.value + num_2.value);
};
};
