I am trying to send a html5 form to flask using the class based MethodView. From what I understand, the def post(self): should contain a request object with the form attributes. However, when I try the below code I get "NameError: global name 'request' is not defined"
flask:
from app import app
from flask.views import MethodView
from app import app
from flask.views import MethodView
from flask import url_for
#app.route('/')
def index():
return app.send_static_file('index.html')
class ImageShareForm(MethodView):
def get(self):
pass
def post(self):
print (request)
app.add_url_rule('/imageshareform/', view_func=ImageShareForm.as_view('imageshareform'))
html:
<form method="POST">
<div class="form-group btn-group-ls well col-md-5">
<legend>Region</legend>
<input class="form-inline" type="radio" name="regions" id="IAD" value="IAD" checked>

Found out I needed to import request that comes with Flask

I am receiving a 'Method Not Allowed - The method is not allowed for the request URL.' error when I click on the 'Logout' button on the Main page. I expect it to go to the index page but I keep receiving an error. I have tried updating the methods for Main and dropsession but neither works. Thanks!
Updated method of '/dropsession' from 'GET' to 'POST'. Still getting same error.
Updated - Fixed by removing methods from '/dropsession' and removing tag from HTML.
main program:
from flask import Flask, request, render_template, redirect, url_for, session, g
import os
app = Flask(__name__)
app.secret_key = os.urandom(24)
#app.route('/', methods=['GET', 'POST'])
def index():
if request.method == 'POST':
session.pop('user', None)
if request.form['password'] == 'admin' and request.form['username'] == 'admin':
session['user'] = request.form['username']
return redirect(url_for('main'))
return render_template('index.html')
#app.route('/main')
def main():
if g.user:
return render_template('main.html', user=session['user'])
return redirect(url_for('index'))
#app.before_request
def before_request():
g.user = None
if 'user' in session:
g.user = session['user']
#app.route('/dropsession', methods=['POST'])
def dropsession():
session.pop('user', None)
return render_template('index.html')

I'm making a user registration form in which I have made a post request to get the user input data in a print out form but 405 Method Not allowed error causing the problem. I'm a newbie so that's why I couldn't figure out what's going wrong.
CONTROLLER CLASS:
import web
from Models import RegisterModel
urls = (
"/", "Home",
"/register", "Register",
"/post", "PostRegistration",
)
render = web.template.render("Views/Templates", base="MainLayout")
app = web.application(urls, globals())
# Classes/routes
class Home:
def GET(self):
return render.Home()
class Register:
def GET(self):
return render.Register()
class PostRegistration:
def POST(self):
data = web.input()
reg_model = RegisterModel.RegisterModelCls()
reg_model.insert_user(data)
return data.username
if __name__ == "__main__":
app.run()
Registration form:
<div class="container">
<h2>Register Account</h2>
<br /><br />
<form>
<div class="form-group label-static is-empty">
<label for="username" class="control-label">Username</label>
<input id="username" name="username" class="form-control"

RegistrationModel.py class (which suppose to print the user input)
import pymongo
from pymongo import MongoClient
class RegisterModelCls:
def insert_user(self, data):
print("data is: " + data)
Error:
http://0.0.0.0:8080/
127.0.0.1:64395 - - [06/Sep/2019 00:19:16] "HTTP/1.1 GET /post" - 405
Method Not Allowed
You're mixing GET and POST.
The Error indicates you're doing a "GET" operation, on the url '/post'.
web.py takes the URL and looks it up in the urls list, and identifies the url '/post' is handled by the class "PostRegistration".
So, web.py calls the GET method on class PostRegistration, which doesn't exist, or, as web.py says "Method Not Allowed".
To get past that, either use a POST operation (as #Barmar suggests) or, rename PostRegistration.POST(self) to PostRegistration.GET(self).
I am basically creating a flask web app which takes username from user and gets his /her codeforces data I am having a problem in extracting the email-id
from the form. I am getting the username but not the email-id.They are both in one form tag in the html file.
Error in browser:

I wrote a simple email script in python that takes the data from a form and emails it using boto. What I need to do now is redirect the user to another page "thankyou.html" without showing any cgi output.
HTML FORM:

Python Script:
#!/usr/bin/python2.7
import cgi
import html
import boto.ses
import cgitb; cgitb.enable() #for troubleshooting
print("Content-Type: text/html")
print
def getdata():
form = cgi.FieldStorage()
name = form["name"].value
company = form["company"].value
phone = form["phone"].value
email = form["email"].value
category = form["category"].value
message = form["message"].value
return name, company, phone, email, category, message
#main Program
if __name__=="__main__":
try:
name, company, phone, email, category, message = getdata()
conn = boto.ses.connect_to_region('us-west-2')
conn.send_email(
'admin#gmail.com',
category,
'%r, %r, %r, %r %r' % (email, name, company,
phone, message),
to_addresses = 'admin#gmail.com'
)
except:
cgi.print_exception()
I only can get redirected to the output for the cgi script, I need to send customers to thankyou.html
I want to post the data to the server via form. How can I do this?
<div class="panel-body">
<form role="form" action="{% url 'login' %}" method="POST">
{% csrf_token %}
<div class="form-group">
<label for="sender-email" class="control-label">Username:</label>
<div class="input-icon"> <i class="icon-user fa"></i>
<input id="sender-email" type="text" placeholder="Username" class="form-control email">
</div>
</div>
<div class="form-group">
<label for="user-pass" class="control-label">Password:</label>
<div class="input-icon"> <i class="icon-lock fa"></i>
<input type="password" class="form-control" placeholder="Password" id="user-pass">
</div>
</div>
<div class="form-group">
<input class="btn btn-primary btn-block" id="authenticate_user" type="submit" value="Submit">
</div>
</form>
</div>
My views.py
#csrf_exempt
def signin(request):
if request.method == 'POST':
print request.POST.get('sender-email') #prints None
username = request.POST['username'] # throws error, username not available.
password = request.POST['password']
How do I post the data without using jquery? I know of a way of posting through AJAX jquery, but dont wanna do that.
The 'name' attribute of input tags is set as keys of request.GET and request.POST.
Add name attribute to all your input tags.
<input name="username" id="sender-email" type="text" placeholder="Username" class="form-control email">
<input name="password" type="password" class="form-control" placeholder="Password" id="user-pass" >
POST data are populated using the name attribute of your input elements. Change your id attributes or add a name one accordingly. E.g:
<input type="password" class="form-control" placeholder="Password" name="user-pass">
You should also consider using a form to handle your data more easily.
