I am having a hard time with tests in Django and Python, for my final project I am making a forums website, but I don't really have any idea how or what my tests should be.

First read the Django testing documentation. You might also want to read this book. It's dated in some areas, but testing is still pretty much the same now as it was in 1.1.
It's a bit much of a topic to cover in an SO answer.
Well, you could test:
If you have the right number of pages for the objects you're paginating.
If the page you're viewing contains the right object range. If trying to access a page that doesn't exist returns the
appropriate error.
If your views for listing objects and object detail return the correct HTTP status code (200)
For starters. Hope that helps you out.

I am trying to get my view to redirect to another page after clicking a button that triggers the POST request. I cannot seem to figure out why the redirect doesn't work or why it doesn't even seem to try to redirect.
Here is my view:
def cart1(request):
if request.user.is_authenticated:
#POST
if request.method == "POST":
#JSON Data
data = request.body
new_data = ast.literal_eval(data.decode('utf-8'))
customer = request.user
user_order = Order(user=customer)
user_order.save()
x = 0
while x < len(new_data.keys()):
obj_title = new_data[x]["title"]
obj_price = new_data[x]["price"]
obj_quantity = new_data[x]["quantity"]
obj_extra = new_data[x]["extra"]
total = round(float(obj_price.replace("$", "")))
m = OrderItem(order=user_order, title=obj_title, price=total, quantity=obj_quantity, extra=obj_extra)
m.save()
x += 1
return redirect('checkout-page')
return render(request, 'cart.html')
Any help would be appreciated, thank you
redirect(…) [Django-doc] produces a HttpRedirectResponse, you need to return it, so:
return redirect('checkout-page')
redirect(…) itself thus does not stop the code flow to redirect return a HTTP redirect response, it constructs such response, and your view should then return that response.
you need to be sure the URL name =checkout-page is in the current app otherwise you need to make it redirect('app:checkout-page')
However,I suggest to use from django.http import HttpResponseRedirect
I have two views. One which is called gameReportRoster, and the other gameReportStats.
The basic flow of the views is as follows:
gameReportRoster receives a PK from another view. It then renders some forms and processed some data to get a list of the players who played in the game, as well as players who are being added to the roster.
When the user hits submit, some business logic is completed with some data stored to a temporary Model. At this point, we then need to call the gameReportStats to render the next set of forms. When calling gameReportStats, we need to pass to it one variable called game.
The issue I am facing is that when we call gameReportStats, the URL is not changing. So the Post Request is getting handled in gameReportRoster, although we should now be in gameReportStats.
def gameReportRoster(request, pk):
#login_required(login_url="/login/")
def gameReportRoster(request, pk):
**QUERIES AND FORM RENDERING HERE**
if request.method == 'POST':
if 'submitRoster' in request.POST:
print('submitRoster Was Pressed')
homePlayedList = request.POST.getlist('homePlayed')
awayPlayedList = request.POST.getlist('awayPlayed')
formsetHome = PlayerFormSet(data=request.POST, prefix='home')
formsetAway = PlayerFormSet(request.POST, prefix='away')
**OMMITED FORM PROCESSING DONE HERE FOR READABILITY**
tempGameResult = TempGameResults(game=game)
tempGameResult.save()
tempGameResult.homePlayers.set(homePlayersPlayed)
tempGameResult.awayPlayers.set(awayPlayersPlayed)
return gameReportStats(request, game)
**MORE QUERIES AND FORM RENDERING HERE**
return render(request, "home/game-report-roster.html", context)
def gameReportStats(request, game):
#login_required(login_url="/login/")
def gameReportStats(request, game):
tempGameResult = TempGameResults.objects.get(game=game)
# teams = Team.objects.filter(id__in=teamList)
homeTeam = Team.objects.get(id=game.homeTeam_id)
awayTeam = Team.objects.get(id=game.awayTeam_id)
teamList = [homeTeam.id, awayTeam.id]
teams = Team.objects.filter(id__in=teamList)
homePlayersPlayed = Player.objects.filter(id__in=tempGameResult.homePlayers.values_list('id'))
awayPlayersPlayed = Player.objects.filter(id__in=tempGameResult.awayPlayers.values_list('id'))
gameResultForm = GameResultForm(teams=teams)
formsetGoalHome = GoalFormSet(
queryset=Goal.objects.none(),
form_kwargs={'players': homePlayersPlayed},
prefix='goalHome'
)
formsetGoalAway = GoalFormSet(
queryset=Goal.objects.none(),
form_kwargs={'players': awayPlayersPlayed},
prefix='goalAway'
)
formsetPenaltyHome = PenaltyFormSet(
queryset=Penalty.objects.none(),
form_kwargs={'players': homePlayersPlayed},

'formsetGoalAway': formsetGoalAway,
'formsetPenaltyAway': formsetPenaltyAway,
'gameResultForm': gameResultForm,
'homeTeam': homeTeam,
'awayTeam': awayTeam,
}
** THIS IF NEVER GETS CALLED **
if request.method == 'POST':
print('Test')
** TEMPLATE GETS PROPERLY RENDERED, BUT URL NEVER CHANGES **
return render(request, "home/game-report-stats.html", context)
urls.py
path('game-report-roster/<str:pk>', views.gameReportRoster, name="gameReportRoster"),
path('game-report-stats/', views.gameReportStats, name="gameReportStats"),
what the actual URL looks like
http://127.0.0.1:8000/game-report-roster/fc4cd6db-d7f9-43b3-aa80-f9d4abfff0e5
Maybe instead of
return gameReportStats(request, game)
try:
return redirect('myappname:your_name_in_urls.py', game)
Im trying to add a custom action to django app, where i can redirect to a html (pdf) page i created.
currently the html page only shows 1 result, What im trying to do is to show as many as objects i selcet from the action bar in django admin. here is my code.. admin.py
def print_pdf(modelAdmin, request, queryset, **kwargs):
from django.template.loader import get_template
from django.http import HttpResponse
from django.shortcuts import render, get_object_or_404
from calculator.models import Transaction
from xhtml2pdf import pisa
chp = []
for f in queryset:
chp.append(f.chp_reference)
for q in range(len(queryset)): # here im trying to know how many times to iterate based on how many qs selected
transaction = get_object_or_404(Transaction, chp_reference=chp[1]) #im not sure what to do here
template_path = 'report-pdf.html'
context = {"transactions":transactions}
response = HttpResponse(content_type='Application/pdf')
response['Content-Disposition'] = 'filename="report.pdf'
template = get_template(template_path)
html = template.render(context)
pisa_status = pisa.CreatePDF(html, dest=response)
if pisa_status.err:
return HttpResponse('we had some errors' + html )
return response
print_pdf.short_description = 'bulk pdf'
actions = [export_csv, print_pdf]
here is my code. I know its messed up, but i been trying to figure out to do this but im lost.
help would be appreciated
What's happening is the difference between the following snipppets.
def f(x)
for i in range(x):
return i ** 2
f(5) # 0 ONLY
def f(x):
results = []
for i in range(x):
results.append(i ** 2)
return results
You're returning after the first iteration, so the loop finishes after the first iteration.
You need to do the same as the second one, collect all results and return them at the end.
To illustrate what you want, this is based on your reply here. You can use something like
transactions = Transaction.objects.none()
for pk in chp:
qs = Transaction.objects.filter(chp_reference=i)
transactions = transaction.union(qs)
return transactions
and improve it based on your needs
With Flask-Admin and Flask how can I submit a form\view based on ModelView from code?
I'm trying to create a separate view\form that would allow user to add multiple entries with one form. Specifically allowing to upload multiple images with common prefix name and common parameters. I'd like to do it by submitting a single-image upload form from code, because it does some additional processing like resizing images and I'd like to let Flask-Admin handle connecting database entries and files.
Here's the form I'd like to submit from code:
class ImageView(ModelView):
def _list_thumbnail(view, context, model, name):
if not model.path:
return ''
return Markup('<img src="%s">' % url_for('media',
filename=form.thumbgen_filename(model.path)))
column_labels = dict(show_in_header="Show In Header?",
path="Image")
form_create_rules = ("name",
"tags",
rules.Text(
"Use this image as header. If more than one image is selected header image will be random each time the page is loaded."),
"show_in_header",
"path")
form_excluded_columns = ("timestamp")
column_formatters = {
'path': _list_thumbnail
}
thumbnail_size = config("media", "thumbnail_size")
form_extra_fields = {
'path': BroImageUploadField('Image',
base_path=IMAGES_FOLDER,
thumbnail_size=(thumbnail_size, thumbnail_size, True),
endpoint="media",
url_relative_path='media',
relative_path=None)
}
def is_accessible(self):
return current_user.is_authenticated
def inaccessible_callback(self, name, **kwargs):
# redirect to login page if user doesn't have access
return redirect(url_for('login', next=request.url))
And here I'm creating a form and I'm just not sure that .process() is the function to submit it? Is there one at all?
lass MultipleImagesUploadView(BaseView):
#expose("/", methods=["GET", "POST"])
def index(self):
if request.method == "POST":
a_form = MultipleImagesForm(request.form)
base_name = a_form.base_name.data
tags = a_form.tags.data
show_in_header = a_form.show_in_header.data
print (request.files.getlist(a_form.images.name))
uploaded_files = request.files.getlist(a_form.images.name)
for i, uf in enumerate(uploaded_files):
try:
name, ext = os.path.splitext(uf.filename)
if ext not in IMAGE_EXTENSIONS:
flash("Image file {} was skipped as it's extension is not supported ({}).".format(uf.filename, ext), category="warning")
continue
image_contents = uf.stream.read()
image_form = ImageView()
image_form.name.data = "{}_{}".format(base_name, i)
image_form.tags.data = tags
image_form.show_in_header.data = show_in_header
image_form.path.data = image_contents
image_form.process()
except Exception as e:
flash ("Unhandled exception: {}".format(e), category="warning")
flash("Images were added to the gallery.", category='success')
a_form = MultipleImagesForm()
print("############", a_form)
return self.render('/admin/multiple_images_upload.html', form=a_form)
I can't figure out a way to submit a form from code, been trying to find the answer in docs and google for hours now with no luck.
Found the issue. In my case I was missing the enctype="multipart/form-data". Without that files part was sent as empty.
Also changed to using from flask_wtf import FlaskForm and enabling it as {{ form.files(class="form-control", multiple="") }} in the template.
Files can then be accessed with uploaded_files = request.files.getlist("files") on POST request, it will hold array of file-objects.
I hope this helps someone. If any additional formatting is required I will add or expand the answer.
I am working on a cartridge project. I have created custom html templates for better visual and now I want to render all data which is coming through cartridge's built in APIs on my custom html pages. For.ex. I have a product.html, on which I want to show all products stored in db (category wise).
Actually, I tried to explore url,
url("^shop/", include("cartridge.shop.urls")),
I am not getting that on which API or Function, this url is hitting.
urls.py file of shop app looks like this, I tested it, none of those url get called,
from __future__ import unicode_literals
from django.conf.urls import url
from mezzanine.conf import settings
from cartridge.shop import views
_slash = "/" if settings.APPEND_SLASH else ""
urlpatterns = [
url("^product/(?P<slug>.*)%s$" % _slash, views.product,
name="shop_product"),
url("^wishlist%s$" % _slash, views.wishlist, name="shop_wishlist"),
url("^cart%s$" % _slash, views.cart, name="shop_cart"),
url("^checkout%s$" % _slash, views.checkout_steps, name="shop_checkout"),
url("^checkout/complete%s$" % _slash, views.complete,
name="shop_complete"),
url("^invoice/(?P<order_id>\d+)%s$" % _slash, views.invoice,
name="shop_invoice"),
url("^invoice/(?P<order_id>\d+)/resend%s$" % _slash,
views.invoice_resend_email, name="shop_invoice_resend"),
]
These are cartridge's views for '/shop/product', '/shop/wishlist' and '/shop/cart'

When you hit shop url, your application will try to use an empty url from your cartridge.shop.urls file. So basically when you would like to check which API / view is called, go to this file and look for something similar to this:
url(r'^$', 'your-view', name='your-view'),
ok after posting your second urls file you have following options:
you call:
/shop/wishlist/ - you are executing a view named wishlist
/shop/cart/ - you are executing a view named cart
/shop/checkout/complete/ - you are executing a view named complete
so just find your views.py file, and all those views are going to be there
