What's the best DRY way to repeat a class based view in Django?
I have an app that acts as a booker for the end-user; it's basically a form that calls various apis (BookerApp). It uses two main APIs but in different ways; It calls Google to get geo-location (retrieving lat-long data) to pass through the second api. The issue is I need to use this app in main WebsiteApp and its subsequent templates but with slight modification to the appearance (templates). I know I can repeat the CBV in the website app and modify the leading rendered template file; but was wondering if there was a better DRY method for this? Here is the current structure Project folder > |___ MainProject |__ settings.py |__ urls.py |__ settings.py |___ WebsiteApp |__ Templates |__ views.py <----- repeat the same CBV (found in booker) to here with DRY method |__ urls.py |__ etc.. |___ BookerApp |__ Templates |__ views.py <--- CBV held here |__ etc.. |___ Static I hope this makes sense; I know my project is all over the place and any recommendations would be welcome. In essence the app in Booker is basically a complicated form that I want to be able to use in other templates (mostly held in the WebsiteApp folder … -

Newletter Views not sending Emails after being saved with no error showing
I have created a newsletter app to send emails to subscribers. After adding a new newsletter and setting it to be equal to published it should send the email, but instead, the newsletter is saved with no emails sent. I am sure that the email setting is correct as I am receiving an email after a successful subscription for testing. Here is the complete views.py def newsletter_signup(request): form = NewsletterUserSignupForm(request.POST or None) if form.is_valid(): instance = form.save(commit=False) if NewsletterUser.objects.filter(email=instance.email).exists(): messages.warning( request, 'Your email is already exists in our database') else: instance.save() messages.success( request, 'Your email has been added in our database') subject = "Thank you for Joining our Newsletter" from_email = settings.EMAIL_HOST_USER to_email = [instance.email] with open(settings.BASE_DIR + "/templates/newsletter_signup_email.txt") as f: signup_message = f.read() message = EmailMultiAlternatives( subject=subject, body=signup_message, from_email=from_email, to=to_email) html_template = get_template( "newsletter_signup_email.html").render() message.attach_alternative(html_template, "text/html") message.send() context = {'form': form} template = "newsletters_signup.html" return render(request, template, context) def newsletter_unsubscribe(request): form = NewsletterUserSignupForm(request.POST or None) if form.is_valid(): instance = form.save(commit=False) if NewsletterUser.objects.filter(email=instance.email).exists(): NewsletterUser.objects.filter(email=instance.email).delete() messages.success( request, 'Your email has been removed from our database') subject = "You have been removed from our newsletter" from_email = settings.EMAIL_HOST_USER to_email = [instance.email] with open(settings.BASE_DIR + "/templates/newsletter_unsubscribe_email.txt") as f: signup_message = f.read() message = … -

Synchronize local CouchDB database with remote CouchDB database when connecting to the internet
The idea is simple, I don't know how the execution is: I'm using CouchDB as an option because it was the only one I found with something like what I need. I have a local application (Python / Django) that writes to a database (CouchDB). The local database should be synchronized whenever possible with the remote database. The connection to the remote database drops a lot so it is important that this web page works locally on the user's computer. Important notes: The database does not have to be exactly CouchDB, it can be another (if there is a better one for this purpose) I am not developing a mobile application, so I will not use a PouchDB, for example. It is actually an offline, but web application, installed on the user's computer. -

Django... How to use different several models in one view function?
Any help??? How can I use many models in one view function? I have "get" query from the form template under Q name... like this: class UserSearchRequestView(TemplateView): model=ForQuery template_name='do_requests.html' def get_results(self): query=self.request.GET.get("q") if query: our_object=ForQuery.objects.filter(query_id__iexact=query) return our_object Now I need to pass this object through the search through three models to get results... I know, I could do something like this: def index(request): company_info = Company.objects.all() director_info = Director.objects.all() context = { 'company_info' : company_info, 'director_info' : director_info, } return render(request, 'index.html', context=context) But it is only if this function is outside of the class... But my function inside of the class already... So it doesn't work in my case... I could do like this: def get_context_data(self, **qwargs): conObject = super(DirDetailView, self).get_context_data(**qwargs) conObject['mcons'] = RequestSell.objects.all() conObject['fcons'] = DirDict.objects.all() return conObject But, then these objects are only good for using them in template? How can I bring several models into one view function, do operations with them and return the result. I'm kind of confused and probably don't see obvious? -
Django MultipleChoiceField how show only one item
I am creating a combobox with multiple choices using the MultipleChoiceField component. Everything works perfectly, but the list that appears in the combo brings repeated the item and subitem. I looked in the documentation but found nothing regarding this problem. As I understand it, the choice parameter requires bringing a tuple. The choice_test() returns [('test0', 'test0'), ('Test1', 'Test1'), ('test3', 'test3'), ...] Is there a way to show only one item? combo_test = forms.MultipleChoiceField( label=_("Combo test"), required=False, choices=choice_test(), widget= autocomplete.Select2Multiple(url='autocomplete_test') ) -
"This Field is Required" even though I am uploading my file
This is a follow up question to my last question: Lists are currently not supported in HTML Input . I have learned that Lists are simply not supported in Django-Rest-Framework browsable API, and I am trying to test my ability to POST data using Postman. The error I am getting is: "This Field is Required" for my BreedImages field even though I am posting it.

Process Text Files with Python Dictionaries and Upload to Running Web Service lab
I want to write a Python script that will upload the feedback automatically without having to turn it into a dictionary. The script should now follow the structure: List all .txt files under /data/feedback directory that contains the actual feedback to be displayed on the company's website. Hint: Use os.listdir() method for this, which returns a list of all files and directories in the specified path. You should now have a list that contains all of the feedback files from the path /data/feedback. Traverse over each file and, from the contents of these text files, create a dictionary by keeping title, name, date, and feedback as keys for the content value, respectively. Now, you need to have a dictionary with keys and their respective values (content from feedback files). This will be uploaded through the Django REST API. Use the Python requests module to post the dictionary to the company's website. Use the request.post() method to make a POST request to http:///feedback. Replace with 35.193.233.100. Make sure an error message isn't returned. You can print the status_code and text of the response objects to check out what's going on. You can also use the response status_code 201 for created success … -
Can i serve media files on production server in Django?
Actually I created a fully functional web app using Django. I don't have much experience to host a Django web app on a production server. But I'm trying.

I'm trying to host my Django app on digital ocean with apache server. Is there any way that I can serve media files using Django in production server. Even I don't have a huge budget to buy a space on Amazon S3. What should I do? -
