I have made an small weather web app in django & it is working properly but
when a wrong city name is entered it start showing KeyError page.
from django.shortcuts import render, redirect
from django.contrib import messages
import requests
#search page
def search(request):
return render(request, 'index.html')
#forecast result page
def forecast(request):
c = request.POST['city']
url = 'http://api.openweathermap.org/data/2.5/weather?q={}&appid=7fee53226a6fbc936e0308a3f4941aaa&units=metric'.format(c)
r = requests.get(url)
data = r.json()
weather = {
'description': data['weather'][0]['description'],
'icon': data['weather'][0]['icon'],
'city': c.title(),
'temperature': data['main']['temp']
}
print(r)
return render(request, 'weather.html', {'weather': weather})
On entering wrong city name it is giving KeyError,So I want that instead of giving KeyError django will redirect it to my homepage i.e index.html with an error message below it.
The API will tell you if the city name is not valid.
r = requests.get(url)
if r.status_code == 404:
messages.add_message('City not found')
return redirect('home')
data = r.json()
...
First of all, please do not construct the querysetring yourself: querystrings can not include a lot of characters. You can use Django's QueryDict for that, like:
from django.http import QueryDict
qd = QueryDict(mutable=True)
qd.update(q=c, appid='7fee53226a6fbc936e0308a3f4941aaa', units='metric')
url = 'http://api.openweathermap.org/data/2.5/weather?{}'.format(qd.urlencode())
For cities like 'New York', it will encode this as:
>>> qd.urlencode()
'q=New+York&appid=7fee53226a6fbc936e0308a3f4941aaa&units=metric'
so it replaces the space with a +.
Furthermore you can use try-except here to redirect to a different page, like:
from django.http import QueryDict
from django.shortcuts import redirect
def forecast(request):
try:
city = request.POST['city']
except:
return redirect('name-of-some-view')
qd = QueryDict(mutable=True)
qd.update(q=city, appid='7fee53226a6fbc936e0308a3f4941aaa', units='metric')
url = 'http://api.openweathermap.org/data/2.5/weather?{}'.format(qd.urlencode())
try:
data = r.json()
weather = {
'description': data['weather'][0]['description'],
'icon': data['weather'][0]['icon'],
'city': c.title(),
'temperature': data['main']['temp']
}
except KeyError:
return redirect('name-of-some-view')
return render(request, 'weather.html', {'weather': weather})
You can use the Django Messages Framework [Django-doc] to show messages to a user.

You have two functions called get_user_info. The second one, which is a view, overwrites the first.
So when your view attempts to call the function, what it actually calls is itself.
Rename the standalone fiction to something else.
I dont understand what I am doing wrong!! I am getting this error everytime i click on submit. This is a simple registration form

Would be really nice if I could get some Help!! Thanks in advance
Your form processing method creates a User and a matching Vendor. But you also have a post-save signal on User that creates a Vendor for that user. That means you end up trying to create two vendors, whereas a OneToOne field implies a unique relationship of one vendor per user.
Either get rid of the signal, or take the Vendor creation code out of the form processing view.
i've a probelem with the request.user.is_authenticated()
this the view.
from django.http import HttpResponseRedirect
from django.contrib.auth.models import User
from django.shortcuts import render_to_response
from django.template import RequestContext
from forms import RegistrationForm
def ContributorRegistration(request):
if request.user.is_authenticated():
'''if user is logged in -> show profile'''
return HttpResponseRedirect('/profile/')
if request.method == 'POST':
'''if post, check the data'''
form = ContributorRegistration(request.POST)
if form.is_valid():
''' if form is valid, save the data'''
user = User.objects.create_user(username=form.cleaned_data['username'],email = form.cleaned_data['email'], password= form.cleaned_data['password'])
user.save()
contributor = user.get_profile()
contributor.location = form.cleaned_data['location']
contributor.save()
return HttpResponseRedirect('profile.html')
else:
'''form not valid-> errors'''
return render_to_response('register.html',{'form':form},context_instance=RequestContext(request))
else:
'''method is not a post and user is not logged, show the registration form'''
form = RegistrationForm()
context={'form':form}
return render_to_response('register.html',context,context_instance=RequestContext(request))
basically,
if the user is logged in then the profile.html is shown: OK
if the user is not logged in and he's not posting data then the form is shown: OK
when i submit the data from the form i receive back this error:
Request Method: POST
Request URL: http://localhost:8000/register/
Django Version: 1.4.1
Exception Type: AttributeError
Exception Value:
'QueryDict' object has no attribute 'user'
Exception Location: /Users/me/sw/DjangoProjects/earth/views.py in ContributorRegistration, line 9
where line 9 is if request.user.is_authenticated():
so seems that the request does not have the user object when submitting the form data.
how can i solve?
Thanks
You're filling your own view function with the request.POST data as if it was the form.
if request.method == 'POST':
'''if post, check the data'''
form = ContributorRegistration(request.POST)
if form.is_valid():
Should be
if request.method == 'POST':
'''if post, check the data'''
form = RegistrationForm(request.POST)
if form.is_valid():
In order to have access to request.user object, you need to have the User authentication middleware installed in your application. To do this (extremely easy), do the following:
Go to your settings.py and add 'django.contrib.auth' and 'django.contrib.contenttypes' to the INSTALLED_APPS tupple.
You are very likely to require a syncdb command for it to be fully installed (you need some database tables for user authentication).
python manage.py syncdb
And that should make it work.
Is it just me or is the name of your form the same as your view function ContributorRegistration?
Perhaps you've made a typo.
I'm having some trouble trying to pass a string from a URL to the views. My page has user pages, and if you go to site.com/username it brings up that users page. But when I try going it says this: [invalid literal for int() with base 10: 'username'].
Here's my code:
urls.py:
(r'^user/(?P<userName>[^/]+)/$', 'mischief_blog.mischief_app.views.user_view'),
views.py:
def user_view(request, userName):
postList = userPost.objects.filter(author=userName)
return render_to_response('user.html', {"user": user_name, "postList": postList}, context_instance=RequestContext(request))
get name from url:
(r'^user/(?P<userName>\w+)/$', 'mischief_blog.mischief_app.views.user_view'),
get user from name, then get posts from user: (get_object_or_404) and (User)
from django.shortcuts import get_object_or_404
from django.contrib.auth.models import User
def user_view(request, userName=None):
user = get_object_or_404(User, username=userName)
postList = userPost.objects.filter(author=user)
return render_to_response('user.html', {"user": user, "postList": postList}, context_instance=RequestContext(request))
