if ipn_obj.receiver_email != "paypalemail#gmail.com":
# Not a valid payment
return
# ALSO: for the same reason, you need to check the amount

"valid_ipn_received" is not firing when i make payments on 127.0.0.1:8000, nor ngrok, nor my production server. What is wrong with my code? I am new to signals.
Have you made sure that your apps.py file is actually being run? You can test by inserting breakpoint() or just a print() call.
You may need to add a line to your module's __init__.py like so:
default_app_config = 'app.engine.apps.EngineConfig'
or similar to make sure that it's loaded. See the documentation on AppConfigs.

I need to check that the post has disappeared from the old group page. I need to get my old group for her slack.
old_group_response = self.authorized_client.get(
reverse('group_list', args=(self.group.slug,))
)
And compare that old_group_response.context['page_obj'].paginator.count equals zero. This means that there are no posts in our old group. And check another new group, that there is 1 post there. How can I write it in the right way?
I know what rubbish is written here (I'm just learning), this is what I was able to sketch.
from django import forms
from django.test import Client, TestCase
from django.urls import reverse
from ..models import Group, Post, User
NEW_POST = reverse('posts:post_create')
class PostFormTests(TestCase):
#classmethod
def setUpClass(cls):

cls.author_auth = User.objects.create_user(username='test auth')
cls.not_author = User.objects.create_user(username='Not Author')
cls.group = Group.objects.create(
title='Test group_title',
slug='test_slug',
description='Test description')
def setUp(self):
self.authorized_client = Client()
self.authorized_client.force_login(PostFormTests.author_auth)
self.authorized_client_not_author = Client()
self.authorized_client_not_author.force_login(
PostFormTests.not_author)
def test_post_old_group_response(self):
""" Check if a post has been removed from the old group."""
post = Post.objects.create(
group=PostFormTests.group,
author=PostFormTests.author_auth,
text='test post')
group_2 = Group.objects.create(
title='Test group_title2',
slug='test_slug2',
description='Test description2')
posts_count = Post.objects.count()
form_data = {
'text': 'text_post',
'group': group_2.id}
old_group_response = self.authorized_client.get(
reverse('posts:group_list', args=(self.group.slug)),
data=form_data,
follow=True)
self.assertEqual(
old_group_response, reverse(
'posts:post_detail', kwargs={'post_id': post.pk}))
self.assertEqual(Post.objects.count(), posts_count)
self.assertEqual(old_group_response.context[
'page_obj'].paginator.count == 0)
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
I am testing my views using Django Unit testing. I am making get and post requests with params to check what status i get back.
But the problem how to check for context variables which are retuned in the response?
For example, on the View Cities page, I make a get request, the context dict in the view has the variable cities. So I want to check for context.
resp = self.client.post(
path=reverse('upload_video'),
data={"video_url": video_url, "pro": 1}
)
self.assertEqual(resp.status_code, 200)
Condition is True both ways, if the form is invalid or valid it returns 200. If I can check for context, then I can check what has been retuned from the view in response.
What I tried
=> resp.__dict__
{'templates': [], '_handler_class': None, '_headers': {'vary': ('Vary', 'Cookie'), 'content-type': ('Content-Type', 'application/json')}, '_charset': 'utf-8', '_closable_objects': [], 'cookies': <SimpleCookie: >, 'client': <django.test.client.Client object at 0x112bace10>, '_base_content_is_iter': False, 'context': None, 'request': {u'CONTENT_LENGTH': 202, u'wsgi.input': <django.test.client.FakePayload object at 0x113667990>, u'REQUEST_METHOD': 'POST', u'PATH_INFO': '/upload/video/modal/', u'CONTENT_TYPE': u'multipart/form-data; boundary=BoUnDaRyStRiNg', u'QUERY_STRING': ''}, '_container': ['{"error": {"msg": "Pro: Select a valid choice. That choice is not one of the available choices.", "head": null}}']}
Check _container has that variable. The form is invalidated, and retuned an error in the context. but when I do the following i get None
=> resp.context
None

The resp (An instance of django.test.Response) should have an context attribute.
You can access context value using context[..]:

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.
