I keep getting the following error when I run my code:
TypeError: 'Response' object is not callable
Here is my code...
from flask import Flask, render_template, flash
import os
import requests
import forms
app = Flask(__name__)
app.secret_key = 'jfdsjajfjds'
mg_key = os.environ['MAILGUN_API_KEY']
#app.route("/", methods=('GET', 'POST'))
def landing():
form = forms.OptinForm()
if form.validate_on_submit():
return requests.post(
"https://api.mailgun.net/v3/lists/test_list#sandbox.mailgun.org/members",
auth=('api', 'mg_key'),
data={'subscribed': True,
'address': form.email.data,
'name': form.first_name.data})
flash("Thanks! Check your email.")
return render_template('landing.html', form=form)
if __name__ == "__main__":
app.run()
I figured out the problem. I was calling my API key variable as a string. fixed it by changing 'mg_key' to mg_key

Hello i am writing the following code to authenticate the username and password and execute a entry method code if the given credentials are valid. But i am getting internal server error.Can someone help where it is getting wrong. My target is to execute a block of code if the credentials are matching.

I was able to run this application with simple changes in the sequence of usage of #auth_decorators.

I have a run.py file at the top level of my directory where I initialize flask-socketio. That file looks like this:
# /run.py
#!/usr/bin/env python
import os
from src.config import app_config
from dotenv import load_dotenv, find_dotenv
from flask_socketio import SocketIO
from src.app import create_app
load_dotenv(find_dotenv())
env_name = os.getenv('FLASK_ENV')
app = create_app(env_name)
socketio = SocketIO(app, async_mode=None)
if __name__ == '__main__':
port = os.getenv('PORT')
# run app
socketio.run(app, host='0.0.0.0', port=port)
My app.py file sits under src/app.py and looks like this:
def create_app(env_name):
"""

# app initiliazation
app = Flask(__name__)
app.config.from_object(app_config[env_name])
# initializing bcrypt and db
bcrypt.init_app(app)
db.init_app(app)
app.register_blueprint(message_blueprint, url_prefix='/api/v1/message')
return app
I am trying to import the socketio instance into /src/views/MessageView.py
My MessageView.py file looks like this:

I have spent the last two days scouring the internet for help on how to fix this. The error i receive is:
ImportError: cannot import name 'socketio'
I have tried relative imports as well as monkey_patching. But each time the error still occurs. Any ideas on how to fix the issue would be greatly appreciated.
P.S. I am adapting the example that Miguel has in his flask-socketio repo located here: link. In his example, everything sits in one file, which would work in a basic app, however, for an app with 50+ API endpoints, that is not an optimal solution.
Why do you have the SocketIO object in the top-level run.py module? Since this is a Flask extension, it is better to have it with all your other extensions in src/app.py:
from flask_socketio import SocketIO
socketio = SocketIO()
def create_app(env_name):
"""
Create app
"""
# app initiliazation
app = Flask(__name__)
app.config.from_object(app_config[env_name])
# initializing bcrypt and db
bcrypt.init_app(app)
db.init_app(app)
# initialize socketio
socketio.init_app(app)
app.register_blueprint(message_blueprint, url_prefix='/api/v1/message')
return app
Then in run.py you can import this object:
from src.app import create_app, socketio
# ...
env_name = os.getenv('FLASK_ENV')
app = create_app(env_name)
# ...
if __name__ == '__main__':
port = os.getenv('PORT')
# run app
socketio.run(app, host='0.0.0.0', port=port)
And in the same way you can import it in your MessageView.py module:
from src.app import socketio
socketio.on('whatever')
def do_something(data):
pass
I have a complete example application that uses this structure here: https://github.com/miguelgrinberg/Flask-SocketIO-Chat.
I'm setting up a flask app that will allow me to input a string and it will pass that string argument to my spider to webscrape a page. I'm having difficulty getting the spider to run on the press of a form submit(integrating scrapy&flask).
I've looked at the following code snippet solutions to no avail:
Run Scrapy from Flask,
Running Scrapy spiders in a Celery task,
Scrapy and celery `update_state`
It definitely appears that there are different ways to complete the task. However - each of the code snippets above does not appear to be working.
routes.py
from flask import render_template, flash, redirect, url_for, session, jsonify
from flask import request
from flask_login import login_required
from flask_login import logout_user

from app.forms import LoginForm

from app.models import User
from werkzeug.urls import url_parse
from app.forms import RegistrationForm, SearchForm
#from app.tasks import scrape_async_job

import requests
import json
#app.route('/')
#app.route('/index', methods=['GET','POST'])
#login_required
def index():
jobvisuals = [
{
'Job': 'Example',
'Desc': 'This job requires a degree...',
'link': 'fakelink',
'salary': '10$/hr',
'applied': 'Boolean',
'interview': 'Boolean'}]
params = {
'spider_name': 'Indeedspider',
'start_requests': True
}
response = requests.get('http://localhost:9080/crawl.json', params).json()
data = response
pprint.pprint(data)
form = SearchForm()
if request.method == 'GET':
return render_template('index.html', title='home', jobvisuals=jobvisuals, form=form, search=session.get('search',''))
job_find = request.form['search']
session['search'] = job_find
if form.validate_on_submit():
print('Working on this feature :D')
flash('Searching for job {}').format(form.search.data)
return render_template('index.html', title='Home', jobvisuals=jobvisuals, form=form)
spider
import scrapy
class IndeedSpider(scrapy.Spider):
name = 'indeedspider'
allowed_domains = ['indeed.com']
def __init__(self, job='', **kwargs):
self.start_url('http://www.indeed.com/jobs?q={job}&l=San+Marcos%2C+CA')
super().__init__(**kwargs)
def parse(self, response):
for item in response.xpath("//div[contains(#class,'jobsearch-SerpJobCard unifiedRow row result clickcard')]").getall():
yield {
'title': item.xpath("//div[contains(#class,'title')]/text()").get(default='None'),
'desc': item.xpath("//div[contains(#class,'summary')]/text()").get(default='None'),
'link': item.xpath("//div[contains(#class,'title')]/#href").get(default='None'),
'location': item.xpath("//span[contains(#class,'location')]/text()").get(default='None'),
'salary': item.xpath("//div[contains(#class,'salarySnippet')]/text()").get(default='None')
}
Expected:
I type in a input box the job, job gets passed to spider on submit, spider scrapes indeed.com and pulls the first page only and returns that data on the index page.
Actual:
Unsure of where to start.
Can anyone point me in the right direction?
I am trying to add a custom error code to a flask_restful API, following the directions given in the docs however I do not receive the correct response and I am getting a NameError: global name 'UnsupportedMediaType' is not defined message. What am I doing wrong here?
# -*- coding: utf-8 -*-
from flask import Flask, request
from flask_restful import Resource, Api
import service
errors = {
'UnsupportedMediaType': {
'message': 'Unsupported Media Type',
'status': 415
}
}
app = Flask(__name__)
api = Api(app, errors=errors)
class Service(Resource):
def post(self):
if request.is_json:
data = request.get_json()
return service.handler(args['data'])
else:
raise UnsupportedMediaType
api.add_resource(Service, '/')
if __name__ == '__main__':
app.run(host='0.0.0.0', debug=True)
You must store the error handler to a function. Like this:
def error(exception):
return {some json error data with the message 'exception'}
now you can call the error handler as you want.
OR
You can use Flask error handler decorator for that. Heres the link
I keep getting the error NameError: global name 'NameForm' is not defined
Here is my views.py
from flask import Flask, render_template
from flask_bootstrap import Bootstrap
from app import forms
app = Flask(__name__)
bootstrap = Bootstrap(app)
#app.route('/', methods=['GET', 'POST'])
def index():
name = None
form = NameForm()
if form.validate_on_submit():
name = form.name.data
form.name.data = ''
return render_template('index.html', form=form, name=name)
if __name__ == '__main__':
app.run(debug=True)
And here is my forms.py
from flask_wtf import Form
from wtforms import StringField, SubmitField
from wtforms.validators import Required
class NameForm(Form):
"""docstring for ClassName"""
name = StringField('Your name please', validators=[Required()])
submit = SubmitField('Submit')
Any ideas on what i might be doing wrong???
