login.html
<form action="/login" method="post" name="login" id="login">
<input autocomplete="off" id="username" name="username" value="{{ hold }}" type="text">
<input id="password" name="password" type="password">
<button type="submit">Log In</button>
</form>
In above I have press submit button, while username is empty.
Then form submit with the post method and return render_template("login.html", xvalue=2) have executed.
After that I have refresh the login web page and I expect the request.method been assumed as default (get) and return render_template("login.html", xvalue=4) get executed.
But xvalue=2 passed, while the form method value is remained post.
#app.route("/login", methods=["GET", "POST"])
def login():
if request.method == "POST":
if not request.form.get("username"):
return render_template("login.html", xvalue=2)
else:
return render_template("login.html", xvalue=3)
else:
return render_template("login.html", xvalue=4)
How can form method variable gets default get value, in case of page refreshed?
This is what i tried and it seemd to work
#app.route("/login", methods=["GET", "POST"])
def login():
if request.method == "POST":
if not request.form.get("username"):
return render_template("login.html", xvalue=2)
else:
return render_template("login.html", xvalue=3)
elif request.method == "GET":
return render_template("login.html", xvalue=3)
hope this helps

This is the form from home.html
def home(request):
if request.method == 'POST':
username = request.POST.get('username')
pass1 = request.POST.get('pass1')
user = authenticate(username=username, pass1=pass1)
if user is not None:
login(request, user)
return render(request,"main_tem/room.html")
else:
return redirect('signup')
return render(request,"main_tem/home.html")
this is home view from views.py in 'main' app.
so as u can see from the home view if user is present or signuped it should redirect user to room.html page but when i try to do it it redirects to signup page which shouldnt happen if user is already present in data base. i am kind of lost here as i dont know what kind of solution i should search for. from what i have observed i think home view is not able to get data from the form in home.html
from django.contrib import admin
from django.urls import path
from . import views
urlpatterns=[
path("",views.home,name="home"),
path("signup",views.signup,name="signup"),
path("rooms",views.rooms,name="rooms"),
]
for reference here is the urls.py from 'main' app
Change this,
def home(request):
if request.method == 'POST':
username = request.POST.get('username')
pass1 = request.POST.get('pass1')
user = authenticate(username=username, pass1=pass1)
if user is not None:
login(request, user)
return render(request,"main_tem/room.html")
else:
return redirect('signup')
return render(request,"main_tem/home.html")
to this:
def home(request):
if request.method == 'POST':
username = request.POST.get('username')
pass1 = request.POST.get('pass1')
auth = authenticate(username=username, password=pass1)
if auth:
login(request, auth)
return render(request,"main_tem/room.html")
else:
return redirect('signup')
return render(request,"main_tem/home.html")
You should be go to go.

thank you
try to put this
<form method="POST" action="{% url 'login' %}">
Also I am not sure if you have properly closed your form with a <\form>.
Please check it.
I do not see what I am doing wrong when trying to add data into the database. When I am pressing the button Submit, nothing is entered in the database. The same happens when pressing the key enter.
Here is my html file.
<script>
$(document).keypress(function(event) {
if (event.keyCode == 13 || event.which == 13) {
alert('enter key is pressed');
event.preventDefault();
}
});
</script>
<div class="col-md-6 col-md-offset-3">
<form method="POST" action="">
<p>
{% csrf_token %}
<input type="hidden" value="{{post.id}}" />
<div class="col-xs-16" style="margin: 0; 0;padding: 3%;">
<label for="inputsm">Oracle</label>
<input class="form-control input-md" type="text" value="{{ post }}">
<input type="submit" value="Submit" style="display: none" /> {{ form.body }}
<button type="submit" value="Submit" class="btn btn-success">Submit</button>
</p>
</div>
</form>
</div>
Here is the views.py
def post_list(request):
posts = Post.objects.all()
category = Category.objects.all()
context = {
'posts':posts,
'cat':category,
}
return render(request, 'journal/post_list.html', context)
def add_post(request):
post = get_object_or_404(Post, pk=pk)
if request.method == "POST":
form = PostForm(request.POST or None)
if form.is_valid():
post = form.save(commit=False)
post.save()
return redirect('post_details', pk=post.pk)
return render(request, 'journal/post_list.html', {'post': post})
else:
form = PostForm()
context = {
"form": form,
}
return render_to_response('journal/post_list.html', context)
Does the form get submitted? If not, maybe try adding some javascript to submit the form, when the key is pressed
$("form").submit();
I have a html page with various submit buttons:
<h3>Add Address</h3>
<form method="post">
{% csrf_token %}
...
<input type="submit" value="Add" name="_add_add">
</form>
<h3> Update values </h3>
<form method="post">
{% csrf_token %}
...
<input type="submit" value="Add" name="_update">
</form>
<h3>Address</h3>
<form method="get">
...display...
My view.py is:
def property(request):
if request.method == 'POST':
if '_update' in request.POST:
...update values...
elif '_add_add' in request.POST:
...add addres....
Context = {"name_for_template":"value"}
else:
... graph default values...
Context = {"name_for_template":"value"}
return render(request, 'address.html', context)
When there isn't a POST and simply a GET (like being redirected to the page), I get an CSRF error in the context (and it asked me to use request_context). Is it possible (and how) to automatically send a default context for the GET, and send a different context for POST without incurring the CSRF error?
you can try this edit code
def property(request):
context = {}
if request.method == 'POST':
if '_update' in request.POST:
...update values...
elif '_add_add' in request.POST:
...add addres....
context["name_for_template"]= "value"
else:
... graph default values...
context["name_for_template"]= "value"
return render(request, 'address.html', context)
if it doesn't work, share your code
Email sending in django code is not working,
it display error "[Errno 10061] No connection could be made because the target machine actively refused it"
these are my VIEWS.PY
def send_email(request):
username = request.POST.get('username', '')
from_email = request.POST.get('from_email', '')
message = request.POST.get('message', '')
if username and message and from_email:
try:
send_mail(username, from_email, message, ['canonizadocharm#ymail.com'])
except BadHeaderError:
return HttpResponse('Invalid header found.')
return HttpResponseRedirect('/contact/thanks/')
else:
# In reality we'd use a form class
# to get proper validation errors.
return HttpResponse('Make sure all fields are entered and valid.')
these are my contact.html
<FORM METHOD="POST" ACTION="/send_email/" >
{% csrf_token %}
Name: <INPUT TYPE="text" NAME="username"><BR>
Email: <INPUT TYPE="text" NAME="from_email"><BR>
Message: <BR>
<TEXTAREA NAME="message" ROWS="10" WRAP="hard">
</TEXTAREA>
<INPUT NAME="redirect" TYPE="hidden">
<INPUT NAME="NEXT_URL" TYPE="hidden">
<BR>
<INPUT TYPE="submit" VALUE="Send">
<INPUT TYPE="reset" VALUE="Clear">
</FORM>
these are my URLS.PY
url(r'^send_email/', views.send_email),
url(r'^contact/', views.contact),
url(r'^thanks/', views.thanks),
and my SETTINGS.PY
EMAIL_HOST = 'localhost'
EMAIL_HOST_USER = ''
EMAIL_HOST_PASSWORD = ''
EMAIL_PORT = 25
EMAIL_USE_TLS = True
Your action value of form must direct to view's url, mailto:canonizadocharm#ymail.com is not a valid path on your server.
UPDATED:
For example, add a new rule to urls.py like,
url(r'^mail/', views.send_mail),
Then change action value to mail.
Have your action value point to a URL, which in turn points to one of your views. For instance, your urls.py can do this.
url(r'^email/', 'project.views.send_email')
This will route your contact form to your send_mail view.
Your form in the templates has no csrf that's why you get an error of "CSRF verification failed".
<FORM METHOD=POST ACTION="/send_email/" ENCTYPE="text/plain">{% csrf_token %}
...........
</FORM>
If you want to know what is csrf just go to this link:
https://docs.djangoproject.com/en/dev/ref/contrib/csrf/
Create email setting in your settings.py, like this for example:
settings.py
# Sending mail
EMAIL_USE_TLS = True
EMAIL_HOST='smtp.gmail.com'
EMAIL_PORT=587
EMAIL_HOST_USER='your gmail account'
EMAIL_HOST_PASSWORD='your gmail password'
views.py
from django.core.mail import send_mail
def send_email(request):
if request.method == 'POST':
username = request.POST.get('username')
message = request.POST.get('message')
from_email = request.POST.get('from_email')
send_mail(username, message, from_email, ['canonizadocharm#ymail.com',])
return HttpResponseRedirect('/contact/thanks/')
else:
return HttpResponse('Make sure all fields are entered and valid.')
