Best time to install third-party packages in a web application?
During development, what is the best time to install third-party packages (like Rails Devise or Django AllAuth) in a web application? What is the best time to integrate the web application with external services (like Twilio, Mailgun and so on)? When developing web applications (Ruby on Rails and Django in my case) I normally try to install third-party packages (like Raild Devise, Django AllAuth, etc.) and integrate my app with external services (like Twilio and MailGun) as soon as possible (mainly to check that everything is working fine). I noticed that most of these thirdy-party packages and services get "muted" during development (by mocking the actual services) and can actually be ignored until the app is ready for staging so I wonder if it could be better to delay this part of my work until I actually need it. How do you deal with this topic? Do you install third-party packages and integrate external services as soon as possible or as late as possible? Is there any specific reason to prefer a way over the other? Is there any accepted "best practice" regarding this topic? -
django authenticate return none at occasionally and check_password return false at occasionally too
On the way to learning django, I encountered a problem. When Django uses authenticate to authenticate users, occasional failures occur. The same username and password can sometimes succeed, sometimes fail, but not always fail. So I feel very troubled. When I debug locally, everything is normal and deployed to the server. Later, after reading the relevant articles, I rewrote authenticate, trying to use check_password to judge whether the account is legitimate, but it still fails occasionally. The same set of account passwords, check_password occasionally returns false, and then I looked through the data to see that make_password can be fixed to generate a password, I tried to generate a fixed password, and then through. After encryption, the password is directly compared with the password in the database to get the user's legitimate data. However, it fails again. Make_password is normal for debugging on my local machine, and the output on the server is different after each password is encrypted. This may also be the reason why authenticate and check_password can not be used. Most importantly, everything is normal for me locally. Doubt is my server reason, I do not know if I have encountered the same problem, the server is … -

How to check the default cache? Django 1.11
I have the following algorithm. Need to implement it. But I can't do it, because I have never worked with a cache before. When you click on the button Get users data in the admin panel creates a file user_data.xlsx in the root of project. Check if the data is forming? __Yes: we redirect the admin on the page with the words 'Data is forming, try in 10 minutes.' __No: ____ Are the data is formed? ______ Yes: return lines '..........' ______ No: write in cache (for 1 hour) that 'the data are formed'; run asynchronously get_user_data (), at the end of the execution we write in the cache (1 hour.) that `the data is formed` and we remove from the cache the key `the data are formed` I tried to implement it, but it works incorrectly( views.py def get_light_cache(request): cache1 = cache['default'] cache1.set('my_key', "Data is forming") #Check if data is forming? if cache1.get('my_key'): #Yes. we redirect the admin on the page with the words "Data is forming, try in 10 minutes." return HttpResponse("Data is forming, try in 10 minutes.") if cache1.get('my_key', None) == None: #No. if cache1: # Is the data formed?

Conditional bulk update in Django using grouping
Suppose I have a list of transactions with the following model definition: class Transaction(models.Model): amount = models.FloatField() client = models.ForeignKey(Client) date = models.DateField() description = models.CharField() invoice = models.ForeignKey(Invoice, null=True) Now I want to create invoices for each client at the end of the month. The invoice model looks like this: class Invoice(models.Model): client = models.ForeignKey(Client) invoice_date = models.DateField() invoice_number = models.ChareField(unique=True) def amount_due(self): return self.transaction_set.aggregate(Sum('amount')) def create_invoices(invoice_date): for client in Client.objects.all(): transactions = Transaction.objects.filter(client=client) if transactions.exists(): invoice = Invoice(client=client, number=get_invoice_number(), date=invoice_date) invoice.save() transactions.update(invoice=invoice) I know I can create all the invoices with a bulk create in 1 query with bulk create, but I would still have to the set the invoice field in the transaction model individually. Is it possible to set the invoice field of all the Transaction models with a single query after I've created all the invoices? Preferably in using the ORM but happy to use raw SQL if required. I know I can also use group by client on the transaction list to get the total per client, but then the individual entries are not linked to the invoice. -

Sitemap Generation: Update lastmod/last_published_at of Page Manually
I have a PublicationsPage and a PublicationPage class. The PublicationsPage shows a list of its direct children and renders them in a short preview list at http://mysite/publications. class PublicationsPage(Page): # ... def get_context(self, request): context = super().get_context(request) publications = PublicationPage.objects.child_of(self).live() context['publications'] = publications return context This means whenever a new PublicationPage is added/deleted/modified the list updates accordingly. But since I am not updating the PublicationsPage the lastmod/last_published_at attribute of the /publications location never changes. Wouldn't this be missleading for a search engine? A really hacky attempt could be to update the last_published_at date of the parent page every time I touch a child entry. class PublicationPage(Page): # ... def save(self, *args, **kwargs): result = super().save(*args, **kwargs) from datetime import datetime parent_page = self.get_parent() parent_page.last_published_at = datetime.now() parent_page.save() return result Any other suggestions? -
Converting JSON response observable to angular (typescript) object array
I have a service API that pulls data from Django-REST. The returned JSON looks like: [ { "manufacturer": "Mfg", "model": "Model", }, { "manufacturer": "Mfg2", "model": "Model2", } ] The service API function getData returns: return this.httpClient.get(`${this.apiURL}/data/`); Note I am using ListAPIView in Django, and I have verified that the above URL returns the JSON object shown above (though I have to add ?format=json to get the raw data outside of Django's APIView). I then have an angular component that calls the service API function to convert the observable to an array of objects: export class Data implements OnInit { private records = Array<object> = []; ... constructor(private apiService: ApiService) {} ngOnInit() { this.getData(); } public getData() { this.apiService.getData().subscribe((data: Array<object>) => {this.records = data}); There are no error or warnings, but in the component's HTML file when I try to access the record array it always has a length of 0. For example, the following will print "0" and an empty table. <P> {{ records.length }}</P> <table> <tr> <th>Manufacturer</th> </tr> <tr *ngFor="let record of records"> <td> {{ record.manufacturer }} </td> </tr> </table> What am I missing? -

One to one class not updating in django
I am relatively new to Django and have been kinda struggling. These are my three models below: class Site(models.Model): siteID = models.CharField(max_length=255, primary_key=True) class EndDevice(models.Model): class Meta: unique_together = ("edevID", "siteID") edevID = models.CharField(max_length=255) siteID = models.ForeignKey(Site, on_delete=models.CASCADE) deviceCategory = models.BigIntegerField() class ThirdCombi(models.Model): siteID = models.OneToOneField(Site, on_delete=models.CASCADE, primary_key=True) endDevice = models.TextField() I am trying to make a table where one siteID displays all the edevID, which is the third model here. This does work using the following serializers.py class CombiSerializer(serializers.ModelSerializer): class Meta: model = ThirdCombi fields = ("siteID", "endDevice") def serialize(devices): d_list = [] fields = ['edevID', 'siteID', 'deviceCategory'] for device in devices: d_list.append(model_to_dict(device, fields=fields)) return d_list And the views.py as follow: class CombiView(generics.RetrieveUpdateDestroyAPIView): queryset = ThirdCombi.objects.all() serializer_class = CombiSerializer def get(self, request, *args, **kwargs): try: s1 = Site.objects.get(siteID=kwargs["pk"]) devices = EndDevice.objects.filter(siteID=s1) a_site, created = ThirdCombi.objects.get_or_create(siteID=s1, endDevice=CombiSerializer.serialize(devices)) return Response(CombiSerializer(a_site).data) except Site.DoesNotExist: return Response( data={ "message": "Site with id: {} does not exist".format(kwargs["pk"])}, status=status.HTTP_404_NOT_FOUND) But once there is an update in EndDevice and I reload the page it gives me an integrity error and if I put an exception to integrity error, I cannot see the changes made in EndDevice reflected in ThirdCombi. Any help will be appreciated in order to …
