I want to make my own site to log in django 1.7.
But when I get logs will be taken to a page to sign in and get a message that there is no such user. My user is in the database.
VIEW
def my_login(request):
if request.method == 'POST':
username = request.POST.get('username', '')
password = request.POST.get('password', '')
user = authenticate(username=username, password=password)
if user is not None:
if user.is_active:
login(request, user)
return HttpResponseRedirect('/')
else:
print "User does not exist"
return render_to_response('tests/login1.html', context_instance=RequestContext(request))
TEMPLATE
<form class="form-horizontal" name="LoginForm" action="./" method="post">
{% csrf_token %}
<div class="control-group">
<label class="control-label" for="username">Username</label>
<div class="controls">
<input type="text" id="username" value="" placeholder="Username">

</form>
You are not sending the username to the view because the name attribute is missing in your input tag. Instead of:
<input type="text" id="username" value="" placeholder="Username">
try this:
<input type="text" name="username" id="username" value="" placeholder="Username">

I am trying to update the password if the user has forgotten while Login-in. But continuously it is giving the same error given below.

I am trying to do is, if my database "USERS" has Email or Phone no. then Paswd will get updated with the new password which is input by the user
Please tell me what I am doing wrong.
I assume you are using Flask. Is your application running in debug mode?
Running the application in debug mode can help identify where the issue is.
The issue is with the email HTML form input. When you submit a form, the data is sent as key=value pairs, in this case you are using Flask so it is a python dictionary. So in the /NewPassword route, when you request request.form['NewPswdInputEmail'], you are grabbing a value in that dictionary submitted from the form with 'NewPswdInputEmail' as a key.
In the form input the key is the name attribute.
That's why you get the KeyError because the name in the email input form has name="loginInputEmail" instead of name="NewPswdInputEmail"
All you need to do is rename loginInputEmail attribute in the email input field to NewPswdInputEmail.
I have this form in html of my site
<form class="row contact_form" action="." method="post" novalidate="novalidate">
{% csrf_token %}
<div class="col-md-12 form-group p_star">
<input type="text" class="form-control" id="firstname" name="first_name" value=""
placeholder="First Name" required>
</div>
<div class="col-md-12 form-group p_star">
<input type="text" class="form-control" id="lastname" name="last_name" value=""
placeholder="Last Name" required>
</div>
<div class="col-md-12 form-group p_star">
<input type="text" class="form-control" id="mobile" name="mobile" value=""

</div>
<div class="col-md-12 form-group p_star">

</div>
<div class="col-md-12 form-group p_star">

<div class="col-md-12 form-group p_star">

</div>
<div class="col-md-12 form-group">
<button type="submit" value="submit" class="btn_3">
SignUp
</button>
</div>
</form>
Now the problem I am facing is:
1)When I try to post data it shows me an error that username is required which i dont want(create_user() missing 1 required positional argument: 'username').
2)There is no mobile number section in auth_user which i want.
I have tried reading the django docs but couldnt understand(OnetoOne thing and custom usermodel thing I couldnt understand both)
Here is my views.py
def signup(request):
if request.method == "POST":
first_name=request.POST['first_name']
last_name=request.POST['last_name']
email=request.POST['email']
mobile=request.POST['mobile']
password=request.POST['password']
cpassword=request.POST['cpassword']
username=request.POST['username']
user=User.objects.create_user(first_name=first_name,last_name=last_name,email=email,password=password,mobile=mobile)
user.save();
return redirect('/')
else:
return render(request,"signup.html")
(The indentations are correct)
Also I want that the users can login using mobile number or email but I dint find any explanation for that.
from django.contrib.auth.models import User
...
class MyUser(models.Model):
user = models.OneToOneField(User, on_delete=models.CASCADE)
# add other custom fields
first_name = models.CharField(...)
...
# create as
user = User.objects.create_user(username=email,...)
my_user = MyUser.objects.create(user=user, first_name=first_name, ...)
# authenticate as
user.authenticate(username=email, password=password)
This might help
Django default auth
So I wanna be able to update information of a router in the database using a form, I wanna have a form pre-populated with that specific router details. The problem is that form.is_valid() is not working
I tried using {{ form.errors }} {{ form.non_field_errors }} and print(form.errors) but none of them worked
views.py (incomplete)
def info_router(request, pk):
rout = Routers.objects.get(sn=pk)
if request.method == 'GET': # Insert the info in forms
form = UpdateRouter()
rout = Routers.objects.get(sn=pk)
args = {'router': rout}
return render(request, "router_info.html", args)
if request.POST.get('delete'):
# Delete router
rout.delete()
messages.warning(request, 'Router was deleted from the database!')
return redirect("db_router")
if request.method == 'POST':
#Updating the form
form = UpdateRouter(instance=Routers.objects.get(sn=pk))
print(form)
print(form.errors)

You never passed request.POST and rquest.FILES. If you want to update the fields and files, you need to form.save() your form:
if request.method == 'POST':
#Updating the form
form = UpdateRouter(request.POST, request.FILES, instance=Routers.objects.get(sn=pk))
print(form)
print(form.errors)
if form.is_valid():
data = form.cleaned_data
mac = data['mac']
form.save()
print(mac)
return redirect('db_router')
else:
print("Invalid form")
If you do not pass request.POST and/or request.FILES, then Django does not consider the form filled in, and it is never considered valid.
If you pass both files and data, then you need to add the enctype="multipart/form-data" to your <form> tag:
<form enctype="multipart/form-data" class="form-horizontal" action="" method="post">
<!-- -->
</form>
you need to create a bound_form
form = UpdateRouter(request.POST)
form = UpdateRouter(request.POST) binds the data to the form class. then validate
the inputs using is_valid().
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:
werkzeug.exceptions.HTTPException.wrap..newcls: 400 Bad Request: KeyError: 'email-id'
<form method="POST">
<div class="field">

def index():
if request.method == 'POST':

I want to post the data to the server via form. How can I do this?

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.
