Is it possible to have an external file input for choicefields in django?
I have ChoiceField in my Django model which consist of several choices and i am using the CheckboxSelectMultiple widget in forms to have multiple select options. models- BREAKFAST_CHOICES = (('fruits', 'A bowl of fruits with nuts'), ('tofu', 'Tofu Omlette'), ('1', 'Option 1'), ('2', 'Option 2'), ('3', 'Option 3'),) breakfast = MultiSelectField(choices=VBREAKFAST_CHOICES, null=True, blank=True, default=False) forms- widgets = { 'breakfast': forms.CheckboxSelectMultiple, } Now, in the future if I want to change the existing choice (options) with some other or add and delete options,how can i do this? Is there an easier way for a non programmer to just externally update a file and achieve this? i.e can my choicefield take an external file containing the list of options which can be edited as and when required. -
Apache2 + mod_wsgi + multiple virtual hosts for subdomains
I'm trying to setup two websites on a single server: domain.com subdomain.domain.com I am using Ubuntu 18.04.4 LTS, Apache/2.4.29, mod_wsgi/4.7.1, Python/3.8. Both the websites are Django applications. I created two virtual environments and installed mod_wsgi in each using the PyPi package and created two files in the mods-available directory and enabled the mods as described here: app1.load app2.load I created two configuration files under sites-available.

Django: retrieving values of ManyToMany Relationship
I am attempting to implement a 'download csv' action in the django admin, to download the data associated with any model. To handle all models together, and to prevent the need for code changes if the model is changed, I am trying to implement one function (download_csv) that programmatically gets the fields associated with the model, and then saves a row for each object with the values of each field filled in. However, ManyToMany relationships result in an error such as: ManyToManyRel' object has no attribute 'value_from_object. How can I retrieve the values of these fields? The function works when downloading Lectures, but not Speakers, since the ManyToMany relationship is "reversed" (i.e. contained in the model Lecture). models.py class Speaker(models.Model): first_name = models.CharField(max_length=200) class Lecture(models.Model): lecture_title = models.CharField(max_length=200) speaker = models.ManyToManyField(Speaker) admin.py def download_csv(modeladmin, request, queryset): ''' Download CSV of all objects in queryset ''' try: main_model = modeladmin.corresponding_model except AttributeError: modeladmin.message_user(request, 'That action cannot be performed on these objects.') return fields = main_model._meta.get_fields() response = HttpResponse(content_type='text/csv') response['Content-Disposition'] = 'attachment; filename=data.csv' writer = csv.writer(response, csv.excel) writer.writerow(fields) for obj in queryset: writer.writerow([field.value_from_object(obj) for field in fields]) return response admin.site.register(Speaker, SpeakerAdmin) admin.site.add_action(download_csv, 'export_csv') -

Why is my formset with filefield always valid?
I have an inlineformset_factory containing a filefield. Every time I submit the form, whether or not a file is attached, the formset is_valid() always returns True. I have set the blank parameter as False for the filefield. When I test the same formset by replacing the filefield with a charfield or just by the form itself (without inlineformset_factory), the code works as expected. Why is this formset always returning True for is_valid()? # models.py class Author(models.Model): author = models.CharField(max_length=128) description = models.CharField(max_length=1000) class BooksFile(models.Model): author = models.ForeignKey(Author, on_delete=models.CASCADE) books_file = models.FileField(blank=False) # forms.py class AuthorForm(forms.ModelForm): class Meta: model = Author fields = ('author', 'description') class BooksFileForm(forms.ModelForm): class Meta: model = BooksFile fields = ('books_file',) BooksFileFormSet = forms.inlineformset_factory( Author, BooksFile, form=BooksFileForm, fields=('books_file',), extra=1, can_delete=False, can_order=False ) # views.py class CreateAuthorView(CreateView): template_name = "author_create.html" model = Author form_class = AuthorForm def get_context_data(self, **kwargs): context = super(CreateAuthorView, self).get_context_data(**kwargs) if self.request.POST: form = self.get_form(self.form_class) context["books_file"] = BooksFileFormSet( self.request.POST, self.request.FILES, instance=form.instance ) else: context["books_file"] = BooksFileFormSet() return context def form_valid(self, form): context = self.get_context_data() books_file = context["books_file"] print(form.data.get("author")) print("books_file.is_valid()", books_file.is_valid()) # ***This always prints True*** return redirect(self.get_success_url()) def get_success_url(self): return reverse("author_list") # author_create.html <form method="post" enctype="multipart/form-data"> {% csrf_token %} <div> {{ form }} </div> <div> … -
How can I combine three inputs into one variable and use it to fetch data from a database using Django?
all! I am working on my first Django project and learning a lot along the way. So far, I have set up a very simple website and am having trouble with the next steps. Through this project, I am hoping to achieve a website that provides users with reliable resources based on how they answer the three questions they are asked. Website Explanation: The user opens the website and is prompted to click a button to go to the first step. The first step asks the user to choose the subject they would like a resource on (for now, all of the listed subjects are related to cooking). Then, they choose their level of expertise (beginner, intermediate, advanced). Finally, they choose a preferred medium for their resource (article/blog, video, book). Based on the subject, their level of expertise, and their preferred medium, the last page will give the user a resource that is retrieved from a linked database. Where I Am Stuck: So far, I have created five pages (home page, one page for each question, and a results page) and have set up the choices for each question. Now, I am having trouble finding a way to combine the … -

Question about overriding the __init__ method of models.Model in Django
I created an app to keep track of inventory and modify it with a form. The updated_by field changes to the current logged in user when the update button is pressed.

Django and post request to an external API in different views
So i want to create a Django App where my users can post data through a form and make a post request to an external API, but getting the response in the same page/view For example, i have my view class Home(TemplateView): template_name: 'home/index.html' And i have my index.html: <form id="formdata" > <select id="options"> <option id="sku">Option 1</option> <option id="sku2">Option 2</option> </select> <input name="number" type="text" id="number"> <select id="price"> <option id="price1">$5</option> <option id="price2">%10</option> </select> <button type="button" data-loading-text="enviando..." onclick="submitInfo()">Send</button> </form> Let's ignore the fact HTML may be wrong, it is a basic structure of a form with selects and input field, but note that i need to pass "product", "number" and "price" as parameters in the post request. The thing is that when the user clics on the submit button, they make a post request to an external api, i know i can do int with JavaScript using fetch, but the thing is that i need to pass my personal Token Key in the body params, also i'd like to hide the real api url hiding it with an url of my website, for example: www.myurl.com/my-api-call So i'm thinking about creating a "external_api_view" with post request, something like this: import requests import time … -

Baffling error filtering Django objects of derived class by values in foreign key linked class
An app I am converting from Django 1.10 to 3.0 contains classes defined as follows (including only relevant fields) : class DataSet(models.Model): ::: class SurveyRunDataSet(DataSet): survey_run = models.ForeignKey('survey.SurveyRun', null=True, on_delete=models.CASCADE, ..) ::: But the following call, which worked fine at Django 1.10, now fails at Django 3.0 : survey_run_id = .. report_ids = (SurveyRunDataSet.objects. filter(survey_run_id=survey_run_id,report__report_type=AnalysisReport.SUMMARY). values_list('report_id', flat=True).distinct()) The error is : Cannot resolve keyword 'survey_run_id' into field. Choices are: aggregatedataset, filtereddataset, flush_date, id, materalised_source_data_set, materialiseddataset, name, primary_dataset, psession_source_data_set, psessiondataset, report, report_id, source_data_set, surveyrundataset Most of the above choices are other classes that inherit from "DataSet". So Django goes delving upwards in a bizarre wrong direction in the class structure, while missing a field item which is right in front of its nose, in the very model the objects.filter() is being applied to. It makes absolutely no sense! The model tables in postgres are exactly as expected : # \d dataset_surveyrundataset dataset_ptr_id | integer | not null status | character varying(10) | not null base_dataset | boolean | not null schema_mapping | text | not null survey_run_id | integer | "dataset_surveyrundat_survey_run_id_8e235a8a_fk_survey_su" FOREIGN KEY (survey_run_id) REFERENCES survey_surveyrun(id) DEFERRABLE INITIALLY DEFERRED # \d survey_surveyrun id | integer | not null default nextval('survey_surveyrun_id_seq'::regclass) ::: … -
i stack over and over in djjango

How to upload and display videos on django

How to import AbstractUser correctly
I am building an API by using DRF, and while I try to register an User django-registeration, I realized that I did not name my custom User differently, I have entries in my database, so if I can save my saved objects it will be better for my members.

Unable to display parent table with child table in a for loop with template tagging in Django
I want to display an unordered list of NBA teams from my teams table database. Within each team, I want an ordered list of players on that team. So basically I want to produce a list of all objects from my parent table and for each object from the parent table I want a list of all objects from the child table related the parent table.

How can I get this Django CreateView to call my Django-FSM transition?
I'm working on an application that allows logged in users to submit news articles to the database where they can be reviewed and editing before being published. Their submissions could also be rejected. I'm using the cool django-fsm package to manage the state changes and django-bootstrap-modal-forms to display the news submission form and submit it via Ajax. I'm having trouble getting my class-based view to trigger the django-fsm transition in my model. The data is saved to the database, but the receive() method never gets called, so I don't get the confirmation email, for example. I can call receive() manually from the command line and generate the email, so I know that part is working.

Django Admin with Django debug toolbar same table being queried multiple times for each column?
I am using django-debug-toolbar and loading a large table with no foreignkeys. The table size is about 20,000 rows - 15mb - however the django list page is taking extremely long to load, 10s+ to load. When i remove columns from the list_display it seems to load faster. When I am querying the entire dataset however using Ref_ICD.objects.all() via get_queryset it doesn't seem to take that long to query, sub 3s - which is as expected because its a linear query.

I'm working on a Django project and i have a problem with URL pattern when i'm using form. So i have a search bar on the home page but also on the search page doing the same search : /home/ and /home/search/ When I search for the first time it redirects me to search wich is normal from home to home/search/. But when i want to search again i want to stay to this /home/search/ but it redirects me to another search like below /home/search/search/ It says error because obviously it's not in the url pattern mentioned in urls.py Actually what i've done is the following (i know it's dirty programming) : if url contains search then <form method="post" action=""> else <form method="post" action="search/"> If it is in home page then go to search page but if it is in search page stay here. I'm wondering if there is a better way to resolve this problem ? Thanks for reading guys and i hope you will help me.
