From_email not functioning in Django
I am able to send emails using env variables etc. from a gmail account--however, it does not show the value of "from_email". I placed it as request.POST['from_email"] and it still shows the email I listed in my settings.py. I am trying to create a contact form from different email users to one recipient (which is in the settings.py) Also, since I put them in env variables--would I need to adjust the file when deploying it through AWS or should I be able to leave it as it is? Thank you! settings.py SECRET_KEY = os.environ.get('SECRET_KEY') EMAIL_HOST_USER=os.environ.get('EMAIL_HOST_USER') EMAIL_HOST_PASSWORD=os.environ.get('EMAIL_HOST_PASSWORD') views.py def contact(request): message = request.POST.get('message', '') from_email = request.POST.get('from_email', '') send_mail('Contact Form', message, from_email, [settings.EMAIL_HOST_USER]) return render(request, 'first_app/contact.html') contact.html <form action="/contact" method="POST"> {% csrf_token %} <input type="email" name="from_email" placeholder="Your email"> <textarea name="message" placeholder="Message..."> </textarea> <input type="submit"/> </form> -

How to create view to display inline models?
I created an admin form that creates model Catalog and has model Product inline to it. I created an index page that lists all of my catalog objects as a link and when I click that link I want to be able to view that catalog's products. I tried making the product page template identical to the catalog page template, but with catalog replaced with product wherever possible. Here is my models.py file class ProductInline(admin.TabularInline): model = Product extra = 1 class CatalogAdmin(admin.ModelAdmin): fieldsets = [ (None, {'fields': ['catalog_text']}), ('Date information', {'fields': ['pub_date']}), ] list_display = ('catalog_text', 'pub_date', 'was_published_recently') list_filter = ['pub_date'] search_fields = ['catalog_text'] inlines = [ProductInline] Here is my catalog template {% load static %} <link rel="stylesheet" type="text/css" href="{% static 'polls/style.css' %}"> {% if latest_catalog_list %} Index <ul> {% for catalog in latest_catalog_list %} <li><a href="{% url 'scrappe:detail' catalog.id %}">{{ catalog.catalog_text }}</a></li> {% endfor %} </ul> {% else %} <p>You made a mistake</p> {% endif %} Here is my product template {% load static %} Detail <ul> {% for product in catalog %} <li><a href="{% url 'scrappe:detail' product.id %}">{{ product.product_text }}</a></li> {% endfor %} </ul> I thought this would display the products within the catalog, but only the … -
Custom fork of a package migrations for heroku
The package fork to which I am referring has no manage.py, so it's not like I can just do a manage.py makemigrations when I add fields to a model. Can anyone help? Here is the package: https://github.com/shanbay/django-vote And here is my fork: https://github.com/mike-johnson-jr/django-vote I added ip field to a model in the package (and some other minor edits). I need to make these migrations and migrate so my web app that uses this forked package can function properly. Will I need to add these migrations manually? More information: So, my package forked package works propertly locally because I was able to run makemigrations in my project locally. I can't do that in heroku (well I can, but they are not actually added and migrate cannot be used with them). I am trying to get my forked package running in production -- it is being hosted at heroku and the migrations do not make it over to the production server. What do I do? -

ListView has been overidden with get_context_data() and get_queryset() (django-filter) but won't display updated ListView
My user needs to dynamically filter to shorten the full list of data produced by default within the ListView. I've referred to the code examples for using django-filter from: Django how to get multiple context_object_name for multiple queryset from single view to single template https://simpleisbetterthancomplex.com/tutorial/2016/11/28/how-to-filter-querysets-dynamically.html https://kuttler.eu/en/post/using-django-tables2-filters-crispy-forms-together/ I've tried to customise def get_context_data() and def get_queryset() for ListView. At present the GET form correctly renders in the HTML template with fields for the user to filter the data with. However, upon submit (clicking the button), the list view does NOT filter, it continues to display the original, full list of data. Although, the list successfully updates using django-filter within a function based view and separate HTML file, I'd strongly prefer to remain in ListView as this page is linked to other views (Create, Delete and Update) and the ListView pagination functionality is needed. My initial guess is that ListView perhaps doesn't accept a user's GET request to dynamically filter as it ALWAYS automatically renders with all data? Thank you for any advice. filters.py - DataIntervalFilter class DataIntervalFilter(django_filters.FilterSet): class Meta: model = Data_Collection_Interval fields = ['staffrowid', 'datacollectstart',] views.py - ListView class DatesListView(StaffRequiredMixin, ListView): model = Data_Collection_Interval template_name = 'Administrator/manDates.html' context_object_name = 'intervals' … -
Send email using environment variables via Django for security
I can send emails using environment variables in my settings.py, however how do I input these variables in views.py? When put the actual email in str--it works; but for extra security, I written it as env. variable and gave me an error: SMTPRecipientsRefused. Also, how do I get it to show the sender's email. It shows in the console, but not when I receive the email.

Custom User Model creates additional groups and permissions table

Avoid validation of foreign key in django rest framework serializer
I write an API for the following models: class TemplateProjectGroup(models.Model): pass class TemplateProject(models.Model): name = models.CharField(max_length=255, unique=True) description = models.CharField(max_length=1024, blank=True) group = models.ForeignKey(TemplateProjectGroup, on_delete=models.CASCADE) project = models.ForeignKey(Project, on_delete=models.CASCADE) avatar_url = models.URLField(max_length=1024, blank=True) The logic is following: User can create an instance of TemplateProject with non existed group field. So if group is not existed, it should be created with a specific ID. So, I have this serializer: class TemplateProjectSerializer(serializers.ModelSerializer): def create(self, validated_data): template_project_group_id = validated_data.pop('group') project = validated_data.pop('project') group, _ = models.TemplateProjectGroup.objects.get_or_create(id=template_project_group_id) template_project = models.TemplateProject.objects.create(**validated_data, group_id=group.id, project_id=project.id) return template_project def update(self, instance, validated_data): template_project_group_id = validated_data.pop('group') group, _ = models.TemplateProjectGroup.objects.get_or_create(id=template_project_group_id) instance.save() instance.update(**validated_data, group=group) return instance class Meta: model = models.TemplateProject fields = ('name', 'description', 'group', 'project', 'avatar_url') and the view: class TemplateProjectsView(generics.ListCreateAPIView): pagination_class = None serializer_class = serializers.TemplateProjectSerializer def get_queryset(self): return models.TemplateProject.objects.all() It works well, when I try to retrieve list of objects, but I cannot create an object using this API, because I get following error: Invalid pk "1" - object does not exist. So, before creating an object, a validation is applied for all fields, and serializer cannot serialize this integer into an object because this object, which is referenced by foreign key, does not exist.

How can I use django-haystack search facets with custom attributes?

How does implementing any djago apps into my own project works?
help needed for general advice with the example on how to implement django apps. I am trying to implement django app called django-simple-polls. After installing the app with... pip install ... ...adding the app in INSTALLED APPS ...the server still runs... ...migrations runs with no problem... ...being able to create basic poll from the admin... questions starts here as I do not know how can I see the poll on the server: 1) urlpatterns = [ ... url(r'^poll/', include('poll.urls')), ] I am guessing polls app is installed somewhere within django so I do not have to create any additional folder/file in my project. Do I need to import a library to use the include() function? It also mean I need to run polls only in that certain url? That means 'poll.urls' already exist? 2) Add this tags in your template file to show the poll: {% load poll_tags %} ... {% poll %}` Again my guess is just to create any template folder and put as base the code above. What does "..." mean?. Where do I put the above code? How do I call that HTML file? Is that pretty much the only way of building apps into a …
