How do you to set model dynamically using django-filter?
From the django-filters doc you set the model for the filter like so import django_filters class ProductFilter(django_filters.FilterSet): name = django_filters.CharFilter(lookup_expr='iexact') class Meta: model = Product #Here you state the model fields = ['price', 'release_date'] I'd like to have a dynamic model so that I don't have to create a filter for each model. How can I pass information (specifically from the view and more specifically the model) to the filter? I experienced a similar issue with django-tables2 where instead I was able to use table_factory() within the view and pass the necessary object via the context variable. Similarly is there a way to prep the filter in the view already with configured with the model so that I can then pass it in the context variable context['filter'] and then rendered in the template as <form action="" method="get"> {{ filter.form.as_p }} <input type="submit" /> </form> ? -
How to withdraw a choice from the model
I have a product model that has a quantity in stock and at the entrance to the basket I would like to withdraw this quantity. I created three products and each has one in stock.But for one, I created a quantity of 10.Then i tried to pull out in TypedChoiceField > choices. But I only need one value for this product. from django import forms from shop.models import Product class CartProductForm(forms.Form): product = Product.objects.all() quantity = forms.TypedChoiceField(choices=[(i.stock, str(i.stock)) for i in product], coerce=int) update = forms.BooleanField(required=False, initial=False, widget=forms.HiddenInput) views.py def cart_update(request, product_id): cart = Cart(request) form = CartProductForm(request.POST) product = Product.objects.get(id=product_id) if form.is_valid(): cleaned = form.cleaned_data cart.add(product=product, quantity=cleaned['quantity'], update_quantity=cleaned['update']) return redirect('cart:cart_show') cart.py def add(self, product, quantity=1, update_quantity=False): product_id = str(product.id) if product_id not in self.cart: self.cart[product_id] = {'quantity': 0,'price': str(product.price)} if update_quantity: self.cart[product_id]['quantity'] = quantity else: self.cart[product_id]['quantity'] += quantity self.save() I know that I need to somehow convey the product ID and use class CartProductForm(forms.Form): product = Product.objects.get(stock=product.stock) Help me please and sorry for my english -

How to implement autosave form using an intermediate model?
I am writing an application on Django. There is a model Article. After a certain period of time, it is necessary to automatically save data from the form in some intermediate model (for example, Draft). And when the user clicks on submit, create an Article and delete the intermediate form. As I understand it, it is being implemented on JS (with ajax). But how best to do it? Any examples? Have ready solutions? Or I need to write yourself (for example, I can send requests after a specified period of time)? <script> //Cycle with given time intervals. //Form processing //ajax request </script> <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script> <form action="/knowledge_base/add/" class="edit_form new_event" id="id_article_form" enctype="multipart/form-data" onsubmit="submitArticleForm(event, this)"> <div class="content_create"> <div class="field inline textarea"> <input type="text" name="title" id="id_title" style="width: 400px;" required="" class="wide" maxlength="254"> </div> <div class="field inline textarea"> <script type="text/javascript" src="/static/ckeditor/ckeditor-init.js" data-ckeditor-basepath="/static/ckeditor/ckeditor/" id="ckeditor-init-script"></script> <script type="text/javascript" src="/static/ckeditor/ckeditor/ckeditor.js"></script> <div class="django-ckeditor-widget" data-field-id="id_text" style="display: block"> <textarea></textarea> </div> </div> </div> <div class="footer_content"> <div class="footer_select"> <div class="field inline footer_inline select"> <div class="subhead">Category:</div> <select name="category" id="id_category" onchange="changeArticleCategory(event, this);" class="select2 select2-hidden-accessible" required="" tabindex="-1" aria-hidden="true"> <option value="" selected="">---------</option> <option value="2">Food</option> <option value="1">Sport</option> </select> <span class="select2 select2-container select2-container--default" dir="ltr" style="width: 82px;"><span class="selection"><span class="select2-selection select2-selection--single" role="combobox" aria-haspopup="true" aria-expanded="false" tabindex="0" aria-labelledby="select2-id_category-container"><span class="select2-selection__rendered" id="select2-id_category-container"><span class="select2-selection__placeholder"> </span></span><span class="select2-selection__arrow" role="presentation"><b role="presentation"></b></span></span></span><span … -

How can I use AWS's Dynamo Db with Django?
I am developing web applications, APIs, and backends using the Django MVC framework. A major aspect of Django is its implementation of an ORM for models. It is an exceptionally good ORM. Typically when using Django, one utilizes an existing interface that maps one's Django model to a specific DBMS like Postgres, MySQL, or Oracle for example. I have some specific needs, requirements regarding performance and scalability, so I really want to use AWS's Dynamo DB because it is highly cost efficient, very performant, and scales really well. While I think Django allows one to implement their own interface for a DBMS if one wishes to do so, it is clearly advantageous to be able to use an existing DBMS interface when constructing one's Django models if one exists. Can someone recommend a Django model interface to use so I can construct a model in Django that uses AWS's Dynamo DB? How about one using MongoDB? -

How to import a class from a directory to the children of another directory
I'm currently trying to import a class from a directory to a child of a different directory. I try not to use sys.path and use relative imports, however it keeps giving the error about attempted relative import with no know parent package.

Django: Console returns "value must be a decimal number" on a CharField defined field?
Right..... so I'm confused about this. The code function that this error was based on is that a user submits a csv file full of specified data. Django would handle the data processing and add the submitted data to a MySQL database. In the midst of debugging some processing errors, and ensuring that all my defined lists match up with the csv file header order and all, Django's Model.save() function wouldn't work. And so I had exceptions turned on and printed to console, where I get this as the error: [u"'value1' value must be a decimal number."] Where 'value1' is the data value to be entered into a CharField defined field. Both my models.py file is defined as string, and MySQL database table via PHPMyAdmin has this field defined as char(N). I guess here is the model definition of the field as reference: x_version = models.CharField(choices=X_VERSION_CHOICES, max_length=32, blank=True, verbose_name='By X Field Version') And here is an sample definition of the choices: X_VERSION_CHOICES = ( ('value1', 'value12'), ('value3', 'value13'), ) The values for this field must be one of the pre-defined string choices, so there isn't any option of changing this value to a Decimal value. Why would Django show this … -

How do I create a django form that displays radio buttons for all foreign keys on the same page?
I am creating a quiz/survey app. My question about basic use of django forms consists of two elements: How may I use a form (such as a ModelForm) to display the options and a radio button for each question on the same page? (I have read the docs but seem currently incapable of producing an effective ModelForm.) How may I return all of the radio button selections to the view by clicking one submit button? I have spent the day reading the docs, online articles, and as many SO answers as I could find. I suspect that there several factors that I have missed. I have resorted to writing the page using template tags. I would like to know learn to use a django form properly. models.py from django.db import models from django.contrib.auth.models import User class Collection(models.Model): date = models.DateTimeField() def __str__(self): return 'Collection of questions' class Question(models.Model): question_text = models.CharField(max_length=400) collection = models.ForeignKey(Collection, on_delete=models.CASCADE, default=None) date_published = models.DateTimeField('date published') @property def options(self): options = self.option_set.all() return options if options.exists() else 'No options for this question' def __str__(self): return self.question_text class Option(models.Model): option_text = models.CharField(max_length=400) question = models.ForeignKey(Question, on_delete=models.CASCADE) def __str__(self): return f'{self.option_text}' class Answer(models.Model): claim_reference_number = models.IntegerField() date_selected = … -

Handling Bad Inbound ISO8601 DateTime Offset with Django Rest Framework
My mobile client is sending up inaccurate datetime offset information. For example: 2019-05-03T17:55:12-0700 The time is actually the correct UTC time however, the offset should read -0000. I can not currently modify the client to correct the issue causing this. So I need to throw out the offset or change it to -0000. In the above example, for this user who has their account timezone settings set to PST, it stores the date in validated_data as datetime.datetime(2019, 5, 4, 0, 55, 12, tzinfo=<UTC>) If client-based time and offset information were synced up, this conversion by DRF would be correct, as it is seven hours off or PST + the current DST. (west coast us is currently -7:00 UTC) The problem is that by the time I reach my ModelSerializer class, the validated_data already contains what DRF believes is now the correct UTC time. Where is the appropriate place to mutate this field on the POST body so that by the time DRF attempts to create the DateTime it will build the correct timestamp? -

Nothing is written to Nginx access.log/error.log - how to troubleshoot?
I have a Django project deployed with Docker on DigitalOcean. I based it off this tutorial, but had to change some things to get it working. I'm getting a 500 error when I try SMTP email registration live (works fine locally), and the proximate issue is that I can't get any more information about this error because nothing is being written to the nginx access.log/error.log (files are always empty) and there's no output to any docker logs I can find. I've been all over Stack Overflow and the Internet-at-large, but found no help. I've tried changing permissions/owner on the log files to match the Nginx worker, made no difference. I've tried re-specifying the default log files (/var/log/nginx/error.log) in Nginx configuration, even though it seems like I shouldn't have to, and that made no difference either.

I need to provide my search results an edismax boost function feed_count follower_count^8.0, which should result in the following URL: http://localhost:8983/solr/ng_core/select?bf=feed_count%20follower_count%5E8.0&defType=edismax&q=shad Closest I came by searching the docs and stackoverflow was to filter using AltParser like this: sqs.filter(text=AltParser('edismax', query, bf='feed count follower_count^8.0') which produces the following query: {!edismax bf='feed count follower_count^8.0' }shad which returns no result at all. I played around in Solr Dashboard and even if I get it to return results, the way Solr parses it is very very different than it does the expected query. I tried reading upon how to add custom query params to the generated query, but the Custom Input method does not fit my need since it can only change the query text and not add parameters. The current workaround I had to do was to do it this way: sqs.query.get_results(defType='edismax', bf='feed_count') So that the extra kwargs get passed on to the final query function, however, I really don't want to jump out of the nice SearchQuerySet chaining, and more importantly, I can't get the paging to work with this nicely: sqs.query.get_results(defType='edismax', bf='feed_count')[offset:offset + page_size] This won't work since the results have already been fetched, and sqs[offset:offset + page_size].query.get_results(defType='edismax', bf='feed_count') This won't work …
