Django dev server using old version of views.py - django

For some reason, the changes I make on the views.py file are not being reflected. I initially made a function inside view.py to return HttpResponse(request.POST.items()). Even after making changes to the function, it's still performing the same thing. I tried clearing the cache of the browser, restarted the server, and also tried deleting the pyc files. Nothing worked. Any guess on why this is happening?
urls.py
from . import views
urlpatterns = [
path('',views.index, name='index'),
path('proceedaction/<str:pk>/',views.ProceedAction.as_view(),name='proceedaction'),
path('uploadct/<str:pk>/',views.UploadCT.as_view(),name='uploadct'),
]
views.py
from django.shortcuts import render,redirect
from django.views import View
from .models import CreatePatient,PatientRecord,FileData
from django.contrib.auth.decorators import login_required
from django.contrib.auth.mixins import LoginRequiredMixin
from .filters import RecordFilter
from django.http import HttpResponse
import json
# Create your views here.
def index(request):
return render(request,'index.html')
class UploadCT(View,LoginRequiredMixin):
def get(self,request,pk):
records = PatientRecord.objects.filter(id=pk)
context={
'record' : records,
}
return render(request,'ct_upload.html',context=context)
def post(self,request):
dbdata = FileData()
return redirect('index')

I had not specified method=POST in the corresponding HTML file. Solved this issue by doing that.

Pass a file path as a URL parameter in Django

I'm using Django to create a webapp. When a user press on a certain button, it needs to pass a file path as parameter and a string parameter to one of my views. I can't simply use the parameter in the URL since the path contains several '/'. The way I have it setup right now is as follows:
parameters.py
class FilePathConverter:
regex = '^[/]'
def to_python(self, value):
value=str(value)
return value.replace("?", "/")
def to_url(self, value):
value=str(value)
return value.replace("/", "?")
urls.py
from django.urls import path
from . import views
from django.contrib import admin
from django.views import generic
from django.urls import path, register_converter
from . import converters, views
register_converter(converters.FilePathConverter, 'filepath')
urlpatterns = [
path('', views.index, name='webpanel-index'),
path('controlserver/<filepath:server_path>/<str:control>', views.index, name='controlserver'),
]
views.py
from django.shortcuts import render
from django.http import HttpResponse
from .models import Server
from django.contrib.auth.decorators import login_required
import subprocess
def controlserver(request, server_path, control):
if request.POST:
subprocess.call(['bash', server_path, control])
return render(request, 'index.html')
However, with this method, I get this error:
Reverse for 'controlserver' with keyword arguments '{'server_path': 'rien/', 'control': 'start'}' not found. 1 pattern(s) tried: ['controlserver/(?P<server_path>[^/]+)/(?P<control>[^/]+)$']
you can use Slug to resolve this patterns by :
from django.utils.text import slugify
path('controlserver/use slug .....', views.index, name='controlserver'),
but you need to put slug at views and templates So check this list of slug and pk :

How to add Django statements to Javascript

I'm trying to implement some JS code in django so anytime i click a button, it returns the current year.. how do i do this
I've tried using some JS events handler in my django based templates
from datetime import datetime
from django.template import Template, Context
from django.http import HttpResponse as toHTML
cont = Context({'dat':datetime.now()})
def say_year(request):
htm = Template("<button onclick='alert({dat})'>click me</button>")
htm = htm.render(cont)
return toHTML(htm)
i'm expecting an alert box showing full datetime.now() methods
I prefer that you do it that way in order to have full control over the template.
1 - make the views.py that way :
from datetime import datetime
from django.template import Template, Context
from django.shortcuts import render
def say_year(request):
context = {
'dat': datetime.now()
}
return render(request, 'mytemplate.html', context)
2- The urls.py should look that way :
from django.contrib import admin
from django.urls import path
from your_app import views
urlpatterns = [
path('admin/', admin.site.urls),
path('my_template/', views.say_year )
]
3- You create a templates folder in the root directory of your project where all your templates will live.
For your question i have create my_template.html and it should be that way :
<button onclick="alert('{{dat}}')">click me</button>
If you have more questions please let me know.

Does django server support url callbacks (webhooks)?

I am trying to implement url callbacks. And trying to test it. But seems like it is not working. I have been following this article for callbacks implementation.
I have defined two urls in urls.py
from django.conf.urls import patterns, include, url
from django.contrib import admin
urlpatterns = patterns('',
url(r'^admin/', include(admin.site.urls)),
url(r'^agent205', 'agent205.views.test'),
url(r'^agent206', 'agent205.views.test2'),
)
and their views in views.py
__author__ = 'rai'
from django.shortcuts import HttpResponse, render_to_response, render
from django.http.request import HttpRequest
import urllib, urllib2, json
from django.contrib.auth.decorators import login_required
import json
from rest_framework.views import APIView
from django.views.decorators.csrf import csrf_exempt
#csrf_exempt
def test(request):
data = {'foo': 'bar', 'hello': 'world'}
print request.body
return HttpResponse(json.dumps(data), content_type='application/json')
#csrf_exempt
def test2(request):
return HttpResponse(json.dumps(request.body), content_type='application/json')
Then I test from postman like
I am getting HTTP 200 OK response instead of getting 202 Accepted. What should I do for callback to work? Or am I missing something
If your issue is to return a 202 HTTP status code instead of the default 200, you could try to use the status parameter as follows:
#csrf_exempt
def test(request):
data = {'foo': 'bar', 'hello': 'world'}
print request.body
return HttpResponse(json.dumps(data), content_type='application/json', status=202)

Custom template in django form wizard - NameError

I am trying to create custom templates for a simple contact form as per the django docs but I am getting a NameError. Looks like a simple issue but I can't figure it out. Any help will be greatly appreciated. The error message is:
"NameError at /contact/
name 'wizardcustomtemplate' is not defined"
where 'wizardcustomtemplate' is the app. Here is my code:
urls.py
from django.conf.urls import patterns, include, url
from django.contrib import admin
admin.autodiscover()
from wizardcustomtemplate.forms import SubjectForm, SenderForm, MessageForm
from wizardcustomtemplate.views import ContactWizard
urlpatterns = patterns('',
url(r'^admin/', include(admin.site.urls)),
url(r'^contact/$', ContactWizard.as_view(FORMS)),
)
views.py
import os
from django.shortcuts import render
from django.shortcuts import render_to_response
from django.http import HttpResponse
from django.http import HttpResponseRedirect
from django.core.mail import send_mail
from django.core.context_processors import csrf
from django.contrib.formtools.wizard.views import SessionWizardView
from django.contrib.formtools.wizard.views import WizardView
from django.core.files.storage import FileSystemStorage
from django.core.files import File
FORMS = [("0", wizardcustomtemplate.forms.SubjectForm),
("1", wizardcustomtemplate.forms.SenderForm),
("2", wizardcustomtemplate.forms.MessageForm)
]
TEMPLATES = {"0": "wizardcustomtemplate/subject.html",
"1": "wizardcustomtemplate/sender.html",
"2": "wizardcustomtemplate/message.html"
}
class ContactWizard(SessionWizardView):
def get_template_names(self):
return [TEMPLATES[self.steps.current]]
def done(self, form_list, **kwargs):
form_data = process_form_data(form_list)
return render_to_response('wizardcustomtemplate/thanks.html', {'form_data': form_data})
def process_form_data(form_list):
form_data = [form.cleaned_data for form in form_list]
return form_data
forms.py
from django import forms
class SubjectForm(forms.Form):
subject = forms.CharField(max_length = 100,initial='Wizard')
class SenderForm(forms.Form):
sender = forms.EmailField(initial='abcd#efgh.org')
class MessageForm(forms.Form):
message = forms.CharField(initial='How r u?')
The form wizard works fine if I don't use the custom templates (FORMS, TEMPLATES etc.) Please let me know if you need additional information.
Solved it by adding import wizardcustomtemplate in views.py as suggested by #Rohan.

Following django form submission, redirect to page using newly created pk

I am trying to redirect the user to edit details of a task after task submission, but am having troubles redirecting to a page based on the newly created pk. Each view works without the return HttpResponseRedirect line. I have also tried arge=(instance.id) and kwargs=(instance.id) for the variable.
views.py
...
from django.http import HttpResponseRedirect, HttpResponseServerError, HttpResponseForbidden, Http404, HttpResponse
from django.core.urlresolvers import reverse
from django.shortcuts import render_to_response, get_object_or_404,render
...
def new_task(request):
...
...
task.save()
instance = task.save()
return HttpResponseRedirect(reverse('task_values', instance.id))
def task_values(request, task_id):
...
urls.py
from django.conf.urls.defaults import patterns, include, url
from django.http import HttpResponseRedirect
from django.views.generic.simple import direct_to_template
urlpatterns += patterns('core.views_entry',
#Task viewing/editing
(r'^task/(?P<task_id>\d+)/$','task_values'),
(r'^enter/$','new_task'),
return HttpResponseRedirect(reverse('task_values', kwargs={'task_id': instance.id}))
Also note that you don't need to save the task twice.
Edit OK, there's another problem. You haven't given your URLs specific names, which means that the only way to identify them is to pass the fully qualified view name:
reverse('core.views_entry.task_values', kwargs=...)
Or, better, use the the url() function to name your URL:
url(r'^task/(?P<task_id>\d+)/$','task_values', name='task_values'),
and you can use the original version I gave above.
Note that the error isn't telling you it's going to enter/<id>/, just that in that view it's trying to create the reverse URL for the redirection and failing.
