Django forms fields not displaying with include tag
I have spent a few days trying to find an answer to my issue. I have been reading and trying answers given to users with similar problems, but none of them worked. I created a contact form and it works perfectly if I open the html where the code for the form is. But when I try to display it on index using the include tag, it shows the submit button, the structure and the style, but not the form fields. This is what I have in my code: views.py from django.http import HttpResponse from django.views import generic from django.views.generic.edit import CreateView, UpdateView, DeleteView from django.core.mail import send_mail from .forms import ContactForm from django.shortcuts import render # Create your views here. def index(request): return render(request, 'landingpage/index.html', {}) #Contact form def contact(request): if request.method == 'POST': form = ContactForm(request.POST) if form.is_valid(): name = request.POST.get ('name') email = request.POST.get ('email') message = request.POST.get ('message') send_mail('Subject here', content, contact_email, [‘xxx@gmail.com'], fail_silently=False) return HttpResponseRedirect('/thanks/') else: form = ContactForm() return render(request, 'landingpage/contact.html', {'form': form}) #Thank you message def thanks (request): return render(request, 'landingpage/thanks.html', {}) urls.py app_name = 'landingpage' urlpatterns = [ # Landingpage urls url(r'^$', views.index, name='landing-index'), url(r'^contact/$', views.contact, name='contact'), url(r'^thanks/$', views.thanks, name='thanks'), ] index.html … -

Is there a practice of purposefully going with very loose TDD workflow? [migrated]
Does TDD always mean to constantly add implementation inside Test-Develop loop? I saw once an efficient developer, who prototyped a part of big web app in Python. He did a few things in a day or two - wrote multiple broken/empty tests at once, as a way to describe system use cases - wrote only mocks and interfaces (abstract classes) for the code that might go into the above sketchy tests - wrote a few thin implementations inside rare the tests, in order to demo how interfaces and top-down api calls are connected That look quick, and efficient to me. That gave a good understanding of how the design works and I believe that looked like a controllable experiment for him. While I myself follow the TDD very standardly - add test/ add code/ add more asserts into test. I almost immediately jump into development of some function body. Is there a word/name for this efficient and broad development in TDD? Does it look more like a personal experience - or it's the part of TDD that I've somehow missed and practice it very literally instead of doing "smart code sketches"? -
Django Custom Authentication not working
I am trying to implementing django custom authentication with custom user model using JWT. I have written CustomUser model and CustomAuthBackend and configured for using JWT. Below is the snapshot of project's settings.py : AUTH_USER_MODEL = 'users.CustomUser' AUTHENTICATION_BACKENDS = ('project.users.backends.CustomAuthBackend', ) REST_FRAMEWORK = { 'DEFAULT_PERMISSION_CLASSES': ( 'rest_framework.permissions.IsAuthenticated', ), 'DEFAULT_AUTHENTICATION_CLASSES': ( 'rest_framework_jwt.authentication.JSONWebTokenAuthentication', ), } JWT_AUTH = { 'JWT_EXPIRATION_DELTA': datetime.timedelta(hours=1), 'JWT_ALLOW_REFRESH': True, } REST_USE_JWT = True LOGGING = { 'version': 1, 'handlers': { 'file': { 'level': 'DEBUG', 'class': 'logging.FileHandler', 'filename': 'debug.log', }, }, 'loggers': { 'django': { 'handlers': ['file'], 'level': 'DEBUG', 'propagate': True, }, }, } Before using custom authentication, I created 2 users and after implementing custom authentication trying to login (http://127.0.0.1:8000/admin/) using one of those credentials but getting "Please enter the correct email and password for a staff account. Note that both fields may be case-sensitive." message. Trying to debug the custom authentication but even prints are not coming on console. Also tried using logging module but its also not working. So I doubt that my custom authentication function def authenticate(self, request, email, password) itself might not being called. Here is the code for that. from project.users.models import CustomUser from rest_framework import authentication import logging class CustomAuthBackend(object): def authenticate(self, request, … -

Django- filtering of the filter object
I want to make a complex filtering on the page using the filtersets.This is my filterset, nicely showing me touples from choosen time and with choosen parameters. #filters.py class workFilter(filters.FilterSet): start__gt = filters.DateTimeFilter(name='time_start', lookup_expr='gte') start__lt = filters.DateTimeFilter(name='time_end', lookup_expr='lte') class Meta: model = Work fields = ('machine', 'program') But I want to add charts explaining the queried data. For that I need informations, like overall count of time. I am querying them like that: #views.py def search(request): work_list = Work.objects.all() work_filter = workFilter(request.GET, queryset=work_list) filter_backends = (filters.DjangoFilterBackend,) ... #some queries to add to context, such as sum_work = Work.objects.aggregate(Sum('time'))['time__sum'] ... return render_to_response( TEMPLATE_DIRS + 'index.html',{ 'filter': praca_filter, 'sum_work': sum_work, ... #context}) But sadly, those queries are according to whole database, not to my filtered set of object. How can I make queries on filtered set work_filter? -
Access StructBlock in a StreamField of a Page.get_children in Wagtail
I try to render a StreamField of a child page in a Page. I don't manage to render the different StructField within the StreamField. Here is my code class DefinitionPage(Page): body = StreamField([ ('definition', blocks.StructBlock([ ('heading', blocks.CharBlock(label='Titre')), ('paragraph', blocks.RichTextBlock(label='Paragraphe')), ])) ]) content_panels = Page.content_panels + [ StreamFieldPanel('body'), ] my template. (DefinitionPage is a child of this page.) {% for post in page.get_children %} <h2><a href="{% pageurl post %}">{{ post.title }}</a></h2> {% for block in post.body %} {% include_block block %} {% endfor %} {% endfor %} post.title is ok but it's like there is no block in post.body. I tried so many things and {% include_block block %} is certainly wrong. I also tried to add a custom template for the StructBlock without success. How can I do ? I am using Django 2.0 and wagtail 2.0 (I'm new to wagtail but I read the doc) Best regards -
How to add a dictionary(or some other data type) to an account I'm Django
I know there is a Django shop you can implement but it doesn't seem to fit my need. I have a python code which returns a 2d list, which I then use jinja to display in HTML. Each list in the 2d list contains information about products and I was wondering if its possible to add an add to basket feature which stores that list to the user, I was thinking in a form of a dictionary, so the user can later see their basket. -
How to complete testing views classes with py.test in Django?

Django auto create slug and integrity error
I'm not understanding this. I have seen the posts here Django - Slugs - Key (slug)=() is duplicated and here Django: Key (slug)=(*) already exists. Here is my error message: django.db.utils.IntegrityError: duplicate key value violates unique constraint "caseAT_case_slug_key" DETAIL: Key (slug)=() already exists. In the docs it says: https://docs.djangoproject.com/en/1.8/howto/writing-migrations/#migrations-that-add-unique-fields Applying a “plain” migration that adds a unique non-nullable field to a table with existing rows will raise an error because the value used to populate existing rows is generated only once, thus breaking the unique constraint. But this is NOT a migration. This is a djangoitem pipeline. The model has the slug being created automatically from the title. Therefore, I did not put slug in the pipeline. If it is expecting to create slug, and balks because it is already there, why isn't it also expecting to create all the other keys? If it isn't in the pipeline, why is it trying to create it now? Because it expects to create it? So I should remove the auto create on that field? Then how is it going to get created? I did want my slugs to be unique. It seems circular and crazy to me, but what difference does that … -

How to use a custom decorator with default Django auth login view
I am using the default Django authentication system. In my urls, I have : urlpatterns = [ ... path('', include('django.contrib.auth.urls')), ... ] Now I have a custom decorator that I want to apply on the login view, similar to how I have applied it on signup. @example_decorator def signup(request): ... But the problem is that I am using default Login View. Is there any way to apply this decorator to the default Auth View? I think that I need to extend the default view but I can't find any example to do so. How can this be done? -
