Django template get value from foreign keys without context
I have the following data model: class Membership(models.Model): slug = models.SlugField() membership_type = models.CharField(choices=MEMBERSHIP_CHOICES, default='Free', max_length=11) price = models.IntegerField(default=50) stripe_plan_id = models.CharField(max_length=40) def __str__(self): return self.membership_type class UserMembership(models.Model): user = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE) stripe_customer_id = models.CharField(max_length=40) membership = models.ForeignKey(Membership, on_delete=models.SET_NULL, null=True) In my nav bar I would like to show the membership_type if the user is authenticated. Is it possible to do it without a view passing the context? I tried the following: {% if request.user.is_authenticated %} {{ request.user.usermembership.membership.membership_type }} {{ request.user.usermembership_set.membership_set.membership_type }} {% endif %} -
How to align deleteCssClass inside a Jquery Formset?
I'm utilizing a javascript code, called Jquery Formset ( https://github.com/elo80ka/django-dynamic-formset/blob/master/src/jquery.formset.js) and I'm trying to adjust the layout, in particular about the deleteCssClass modifying the script code: .. addText: '+', deleteText: '-', addCssClass: "btn btn-primary", // CSS class applied to the add link deleteCssClass: "btn-primary", // CSS class applied to the delete link .. But the button delete is not in line with the forms, and the result is the following: I have insert the form in a table and I have delete the single Lables replacing them with the table head. Below the code of my tamplate: <main role="main" class="col-md-9 ml-sm-auto col-lg-10 px-4"> <h2>Inserimento costi</h2> <hr> <div class="form-group"> <form action="." method="post"> {% csrf_token %} <div> {{ form.as_p }} </div> <table class="table"> {{ costi_materiali_form.management_form }} {% for form in costi_materiali_form.forms %} {% if forloop.first %} <thead> <tr> {% for field in form.visible_fields %} <th>{{ field.label|capfirst }}</th> {% endfor %} </tr> </thead> {% endif %} <tr class="{% cycle row1 row2 %} form-group formset_row1"> {% for field in form.visible_fields %} <td> {# Include the hidden fields in the form #} {% if forloop.first %} {% for hidden in form.hidden_fields %} {{ hidden }} {% endfor %} {% endif %} {{ field.errors.as_ul }} {{ … -

AJAX in Django page refreshing issue
I have a database with user saved items. On their account the list of those items is displayed; a button next of each items can remove them from the database. Whenever I click on one of the items, their is 5 'delete icons' showing up next to each item. I am using Pagination set on 5 items to display them. But as well with console.log() I realize that whatever button I select my first button is selected. I know the AJAX call is working because the first item is removed from my database. My HTML: {% for saved in saved_list %} <div class="card mb-3" style="width: 49%;"> <div class="row no-gutters"> <div class="col-md-2 my-auto"> <img class="mx-auto d-block " style="width:auto; height:auto; max-width:100px; max-height:100px; " src="{{ saved.sub_product.picture }}"> </div> <div class="col-md-9"> <div class="card-body"> <h5 class="card-title"><a href="{% url 'finder:detail' saved.sub_product.id %}" class="aaccount">{{ saved.sub_product.real_name}}/ {{ saved.sub_product.real_brand }}</a> </h5> <img src="/static/finder/img/nutriscore-{{ saved.sub_product.nutrition_grade}}.svg" style="width:70px;"><br> </div> </div> <div class="col-md-1 my-auto mx-auto"> <form class="form_id" method='post'>{% csrf_token %}{{ saved.id}} <button class='substitut' type="submit" value='{{ saved.id}}'><i class='fas fa-trash'></i></button> </form> </div> </div> </div> </div> {% endfor %} My AJAX: $(".form_id").on('submit', function(event) { event.preventDefault(); var product = $('.substitut').val(); console.log(product); var url = '/register/delete/'; $.ajax({ url: url, type: "POST", data:{ 'product': product, 'csrfmiddlewaretoken': $('input[name=csrfmiddlewaretoken]').val() }, datatype:'json', … -

In my App.vue file i try to load img: <img src="/static/webapp/img/logo.png" alt="logo"> In production I use nginx which is directing /static path into static folder that I share and it's working. But in the development when i run my django on localhost:8000 and load this js from my App.vue it's trying to get the image from localhost:8000/static/webapp/img/logo.png. I would like it to take from localhost:8082/static/webapp/img/logo.png (localhost:8082 is where webpack is running) where it can be found. I tryied to change publicPath in my webpack.config.js: if (process.env.NODE_ENV === 'development') { module.exports.output.publicPath = 'http://localhost:8082/' } but it does not change default behaviour and the img asset src is still localhost:8000/static/webapp/img/logo.png.

How do you create a custom ChoiceField widget in Django?
I am trying to create a custom select field widget that includes at bootstrap input group. I can get the select element to render, but none of the options get rendered. The only documentation I can find is on creating custom widgets using text inputs. I have copied some of the below code from the Django source code hoping that would solve the issue, but the options are still not generated. Any help would be appreciated. widgets.py from django.forms import widgets from django.template import loader from django.utils.safestring import mark_safe class Select2(widgets.Select): template_name = 'widgets/select2.html' option_template_name = 'widgets/select2-options.html' def render(self, name, value, attrs=None, renderer=None): context = self.get_context(name, value, attrs) template = loader.get_template(self.template_name).render(context) return mark_safe(template) select2.html <select class="form-control select2" name="{{ widget.name }}">{% for group_name, group_choices, group_index in widget.optgroups %}{% if group_name %} <optgroup label="{{ group_name }}">{% endif %}{% for option in group_choices %} {% include option.template_name with widget=option %}{% endfor %}{% if group_name %} </optgroup>{% endif %}{% endfor %} </select> <div class="input-group-append"> <button type="button" class="btn btn-success" data-toggle="modal" data-target="#modal-xl"><i class="fa fa-plus"></i></button> </div> select2-options.html <option value="{{ widget.value|stringformat:'s' }}">{{ widget.label }}</option> -
Django admin: using extra field to filter dropdown values
I have a treebeard model like this (simplified version) from django.db import models from treebeard.mp_tree import MP_Node class CompanyHierarchy(MP_Node): department = models.CharField(max_length=30) employee_title = models.CharField(max_length=300) employee_name = models.CharField(max_length=300) It has 6 levels of depth and thousand of records. Now I'd like to add a new model with relationships between employees class Links(models.Model): from = models.ForeignKey("CompanyHierarchy", related_name='source', verbose_name='Документ', on_delete=models.CASCADE) to = models.ForeignKey("CompanyHierarchy", related_name='destination', verbose_name='Ссылка', on_delete=models.CASCADE) Now, CompanyHierarchy has thousands of records, so adding new Links through django admin panel is very cumbersome, as you have to pick one record from thousands in dropdown menu. How can I make this more user friendly? I was thinking of adding extra fields in django admin so that dropdown menu options could be filtered down. For example, adding extra field department, so that I can pick it first, and then dropdown menu for from would be filtered to include only that department. Or (even better) adding an extra field for setting depth first (treebeard creates this field), then having an extra field that will show only records of this selected depth, then filtering options in dropdown menu to include only records that are children of selected item (using path field that treebeard also creates).

Django not sending emails to local
I am very new to django and previously had emails sending to my terminal using: python -m smtpd -n -c DebuggingServer localhost:1025 I am trying to access the PasswordResetConfirmView template but cannot access the url as it is not appearing in my terminal.

Deserializing Nested JSON API response with Django
I'm pretty new to the DRF and serializing/deserializing. I'm slowly building a dashboard for my business during the corona virus and learning to code. I am in a little deep, but after spending more than $10k on developers on upwork and not really get much result, I figured, what do I have to lose? Our software provider has a full API for our needs https://developer.myvr.com/api/, but absolutely no dashboard to report statistics about our clients reservation data. The end result will be a synchronization of some of the data from their API to my database which will be hosted through AWS. I chose to do it this way due to having to do some post processing of data from the API. For example, we need to calculate occupancy rates(which is not an endpoint), expenses from our accounting connection and a few other small calculations in which the data is not already in the provided API. I originally wanted to use the data from the API solely, but I'm hesitant due to the reasons above. That's the backstory, here are the questions: The API response is extremely complex and nested multiple times, what is the best practise to extract a replication … -

Requests download to media server in django
I have this module that I imported into django. It uses request to download files from specific urls. This works well given that the host is my system. If I move to a server, this would mean the files would get downloaded to the server and that is not efficient or good at all. How can I use this module to download and automatically upload to media server or better still, download directly to the media server and from there, serve it up to user to download. This is the script's code def download_course_file(self, course): username = self._login_data["username"] p = Path(f"{username}-{course}.txt").exists() if not p: self.get_download_links(course) statime = time.time() with open(f"{username}-{course}.txt", "r") as course_link: data = course_link.read().splitlines(False)[::2] p.map(self.download, data) def download(self, url): response = self._is_downloadable(url) if response: name = response.headers.get('content-disposition') fname = re.findall('filename=(.+)', name) if len(fname) != 0: filename = fname[0] filename = filename.replace("\"", "") print(filename) else : filename = "Lecture note" with open(filename, 'wb') as files: for chunk in response.iter_content(100000): files.write(chunk) I omitted the self._is_downloadable() logic since it doesn't apply here def download_course(request, id): course = course = get_object_or_404(Course, id=id) course_name = (course.course_name)[:6] person, error = create_session(request) if "invalid" in error: data = {"error":error} return JsonResponse(data) person.download_course_file(course_name) data = {"success":"Your … -

How to add correctly add JSONField to RegisterSerializer in Django?
I'm building a web app at the moment that lets people build pages. These pages should be stored as JSON in my Postgres Database. I've implemented a customer user manager/model in Django: from django.contrib.auth.models import ( AbstractBaseUser, BaseUserManager, PermissionsMixin ) from django.db import models from django.utils import timezone from django.utils.translation import gettext_lazy as _ from django.contrib.postgres.fields import JSONField class UserManager(BaseUserManager): def create_user( self, email, page, username, password=None, commit=True): """ Creates and saves a User with the given email, first name, last name and password.

Django - making API call with user input
I'm creating a Django webapp where the user will input a zip code then the page will display a list of establishments in that area using the Yelp API. homepage.html <form method="GET" action="{% url 'homepage' %}"> {% csrf_token %} <label>Zip Code: </label> <input name="zip_code"> <button type="submit">Submit</button> </form> yelp.py def get_name(location): """ makes call to Yelp API and returns list of establishments within the given zip code """ restaurants = [] url = 'https://api.yelp.com/v3/businesses/search' params = { 'location': f'{location}' } headers = {'Authorization': f'Bearer {YELP_KEY}'} response = requests.get(url, params=params, headers=headers).json() for business in response['businesses']: restaurants.append(business['name']) return restaurants I'm super new to this so I'm unsure how to take the input from homepage.html and use it to make the API call in yelp.py. I know there are Views and Models and Forms, I'm just confused what each of them do and how to use them in this scenario. Let me know if there's more info I can provide. -
How to setup uWSGI vassal names for better log reference?
INFO: Framweork: Django 2.X < 3.x ; Services: supervisord; uWSGI Host: CentOS Linux 7 Hello, i am currently testing how to deploy multiple django apps with uWSGI on my host. I set everything up based on manuals provided by my Host & uWsgi and it works. However i would like to customized everything a bit further, so that i can understand everything a bit better. As far as i understand my uWSGI service uwsgi.ini currently works in an emperor mode and provides vassals for my two different app named baron_app.ini and prince_app.ini to handle my different apps. Question I noticed that the err.log is a kind of confusing for debugging with multiple apps. for instance... announcing my loyalty to the Emperor... Sat May 2 21:37:58 2020 - [emperor] vassal baron_app.ini is now loyal.... [pid: 26852|app: 0|req: 2/2]..... Question: Is there a way to give my vassals a name so that it will printed in the Log ? Or a way to tell uWSGI to set some kind of process & app log relation (Emperor - Vassals - Worker etc.) in the Log? For instance i could imagine something like this, could be easier when it comes to find errors. #baron_app: …
