How to pass html form variable to python function with django

Question

I know this might be a very stupid question, but i'm new to django and try to solve this problem for several houres now. I want to pass a variable from a html form to the backend an then use the variable there to make an api request. Then i want to pass the result of the api-request back to the index.html page.

For example:

index.html

<form action="#" method="post"> {% csrf_token %} <input type="text" class="form-control" id="city" placeholder="" value=""> <input type="submit" value="Submit"> </form>

forms.py

import requests api_address='http://api.openweathermap.org/data/2.5/weather? appid=KEY&q=' city = FORM-VARIABLE url = api_address + city json_data = requests.get(url).json() kelvin = json_data['main']['temp'] temperature = round(kelvin - 273.15,0)

And then show the temperature in the index.html

your inputs must have a name attribute. After that you can look at this question: stackoverflow.com/questions/4706255/… — Cfreak

Use name attribute to send value to views : name='city' via form

<form action="#" method="post"> {% csrf_token %} <input type="text" class="form-control" id="city" placeholder="" value="" name='city'> <input type="submit" value="Submit"> </form>

You will need a view to send it back to template

 def myView(request): context = {} if request.method == 'POST': city = request.POST.get('city') api_address='http://api.openweathermap.org/data/2.5/weather? appid=KEY&q=' url = api_address + city json_data = requests.get(url).json() kelvin = json_data['main']['temp'] context['temperature'] = round(kelvin - 273.15,0) render(request,'template_name.html',context)

In template, it's accessible via {{ temperature }}
