Django form is saying field is required despite providing value
I have a form with a required field customer_phone_number and despite passing a phone number in with the data the form isn't valid.. class OrderForm(forms.ModelForm): class Meta: model = models.Order fields = ( 'date', 'customer_phone_number', ) def __init__(self, *args, **kwargs): super().__init__(*args, **kwargs) self.fields['customer_phone_number'].required = True self.fields['customer_phone_number'].widget = PhoneNumberPrefixWidget() data = { 'date': '2020-04-20', 'customer_phone_number': '+17168567800', } form = OrderForm(data=data) form.is_valid() print(form.errors) # {'customer_phone_number': ['This field is required.']} The only thing I can think of is that I'm using a custom widget but I have no idea how to correct this error. from phonenumber_field.phonenumber import PhoneNumber from django.forms import Select, TextInput from django.forms.widgets import MultiWidget class PhonePrefixSelect(Select): initial = '+1' def __init__(self, attrs=None): choices = [('+1', '+1')] super().__init__(attrs, choices=sorted(choices, key=lambda item: item[1])) def render(self, name, value, *args, **kwargs): return super().render( name, value or self.initial, *args, **kwargs) class PhoneNumberPrefixWidget(MultiWidget): """ A Widget that splits phone number input into: - a country select box for phone prefix - an input for local phone number """ def __init__(self, attrs=None): widgets = ( PhonePrefixSelect(attrs={ 'class': 'form-control w-25 mr-2', 'tabindex': '-1' }), TextInput(attrs={ 'class': 'form-control w-75' }), ) super().__init__(widgets, attrs) def decompress(self, value): if value: if type(value) == PhoneNumber: if value.country_code and value.national_number: return ["+%d" % … -
Reuse django urls patterns and views
I have a usecase where I would like to reuse a bunch of existing views and url patterns. Current situation is a product with about 20 views for it: urlpatterns = [ # product url(r'^product/(?P<pid>\d+)$', views.view_product, name='view_product'), url(r'^product/(?P<pid>\d+)/something$', views.view_something, name='view_something'), url(r'^product/(?P<pid>\d+)/morethings', views.view_morethings, name='view_morethings'), url(r'^product/(?P<pid>\d+)/deeper/things$', views.view_deeper_things, name='view_deeper_things'), ... etc. So I can browse to the following urls: https://host/product/1 https://host/product/1/something https://host/product/1/morethings https://host/product/1/deeper/things In the new situation I want to add additional ways to browse to the products, i.e. product name or some key valuepair. i.e. https://host/product/name/product1 https://host/product/name/product1/something https://host/product/name/product1/morethings https://host/product/name/product1/deeper/things and https://host/product/meta/property1/value1 https://host/product/meta/property1/value1/something https://host/product/meta/property1/value1/morethings https://host/product/meta/property1/value1/deeper/things where I use a database query in the view to find the product by name, or by the specified property+value. How can I reuse patterns and views to avoid having 20 new views and patterns for each way of identifying a product? I could just list all the (20x3) possible patterns and add 20 more for each new way of identifying products. url(r'^product/(?P<pid>\d+)/something$', views.view_something, name='view_something'), url(r'^product/(?P<pid>\d+)/morethings', views.view_morethings, name='view_morethings'), url(r'^product/(?P<pid>\d+)/deeper/things$', views.view_deeper_things, name='view_deeper_things'), url(r'^product/name/<str:name>/something$', views.view_something_name, name='view_something_name'), url(r'^product/name/<str:name>/morethings', views.view_morethings_name, name='view_morethings_name'), url(r'^product/name/<str:name>/deeper/things$', views.view_deeper_things_name, name='view_deeper_things_name'), url(r'^product/meta/key/<str:name>/<str:name>/something$', views.view_something_meta, name='view_something_meta'), url(r'^product/meta/key/<str:name>/<str:name>/morethings', views.view_morethings_meta, name='view_morethings_meta'), url(r'^product/meta/key/<str:name>/<str:name>/deeper/things$', views.view_deeper_things_meta, name='view_deeper_things_meta'), I know I could do: urlpatterns = [ # product url(r'^product/(?P<pid>\d+)$', views.view_product, name='view_product'), url(r'^product/name/<str:name>$', views.view_product, name='view_product_by_name'), And have default … -
Django Template `With` Operator complex boolean assignment
I am creating a Django template that has columns only visible to admins. Currently I am using a template tag has_group that works well. I have to include some logic for superusers. {% if request.user|has_group:"Admins" or request.user.is_superuser %} <th class="detail_btn_col" scope="col">Detail</th> {% endif %} ... Similar code for the <td> But it's making a query for every row of a table. Not terrible but I would like to just set the value once at the start of the template. I saw that I could assign a variable using with and that would accomplish what I want. {% with has_admin_view=request.user|has_group:"Admins" or request.user.is_superuser %} Does not work. {% with has_admin_view=request.user|has_group:"Admins" %} The above works, but superusers aren't included. Is there a way to do AND/OR operations in Django template's WITH statement? -

How to save a string without explicit escaping?
I am trying to make my Django based API return an HTML snippet as a string. I am retrieving the HTML snippet through a BeautifulSoup bs4 element. To convert it into a string, I am simply using the str() operation as follows: test['key'] = str(bs4_element) When I retrieve this value from an API call, I get the HTML code, however, with backslash characters inserted throughout to escape special characters, somewhat like this: "key": "<div class=\"hackdown\"><style id=\"MathJax_SVG_styles\">... I want to render this retrieved HTML in a browser, however, the introduced backslash characters are not letting me do the same. How do I convert the bs4 element such that the above is prevented? -

Django conditional for rendering template
I am new to django and am trying to only render text which does not have the word 'After' or 'Before' in it. However this didnt break anything but it didnt actually remove those values? I looked at using a regex but this really isnt recommended for django templates. {% if "After" not in window.name or "Before" not in window.name %} {{window.event_id}}-{{window.name}} {% endif %} The codebase I am working on makes it almost impossible to remove these values in the models before you get to the template... I can only apologise for maintaining and putting up with this! -

Django Rest Framework, Why does separate serialization class for Image fields is been required?
When serializing a model that contain image field, separate serialization class was been required. Why can't we serialize the model completely in single class ?

CSS loaded but not takes effect on the display
I always get stuck at CSS. I have a table, which works perfectly fine on large screens, and for mobile devices I want the table to be in a card format. I got an idea of creating another div and made the UI for mobile devices as well. And Using CSS, I tried... resp.css .immobile{ display: none; } .immonitor{ display: block; } @media screen and (max-width: 764px){ .immonitor{ display: none; } .immobile{ display: block; } } List.html <tbody> {% for order in order_list %} <div class="immonitor"> <tr> <td>{{ order.id }}</td> <td>{{order.client_name}}</td> <td>{{order.event_name}}</td> <td>{{order.event_date}}</td> <td>{{order.location}}</td> <td><a href="{% url 'order_detail' order.id %}">View</a></td> </tr> </div> <div class="immobile"> <tr> <td> <div> {{order.client_name}} <br> <h3>{{ order.id }}</h3> </div> <div class="pull-right"> {{order.event_name}}<br> {{order.event_date}}<br> {{order.location}}<br> </div> </td> </tr> </div> {% endfor %} </tbody> Now, the CSS doesn't have any effect on the table, it displays both card and table. And the CSS is perfectly loaded. -
Django getting the option value from a drop down menu
I am creating a Django page and I have two drop down menus. The first drop down menu will select a test. Then based on whatever test they selected, it should populate the second drop down menu with some ManyToMany fields. Here is my drop down menus <form> <select name="test"> {% for test in test %} <option value={{ test.name }}>{{ test.name }}</option> {% endfor %} </select> </form> <form> <select name="event"> {% for applicable_events in test %} <option value={{ applicable_events.name }}>{{ applicable_events.name }}</option> {% endfor %} </select> <input type="submit" value="Submit"> </form> The first form is correctly populating all of my tests. Now when the user selects one of the options in the first drop down, I am trying to get whatever they selected so that I can then populate the second drop down.

Django Sum positive values seperate from negative values

Can I merge them efficiently without looping manually or is there a way to do both in a single query? -

How to correctly use MongoDB client connections
I'm building a simple test web application that stores info users enter in a mongo database. No errors come up, but I always get the following warning (Im using django) when using the client. /home/<User>/.local/share/virtualenvs/<Name>/lib/python3.7/site-packages/pymongo/topology.py:155: UserWarning: MongoClient opened before fork. Create MongoClient only after forking. See PyMongo's documentation for details: http://api.mongodb.org/python/current/faq.html#is-pymongo-fork-safe "MongoClient opened before fork. Create MongoClient only " After checking out the API docs, it seems that the warning pops up when using fork() which im not explicitly using. Maybe something that I'm doing is actually triggering the fork. I create my mongo client at __init__ and then import the variable to my mongoDB handler. Then, that client that I imported is used inserting or updating items in the DB. What is the correct way of creating and then using a mongo client to prevent this warning from appearing? -
Confused by Django Rest Framework Permissions
I have a complex set of permissions that I want to apply to my views, but I'm having a hard time understanding where to put them. Here are my basic permissions. List all projects: If the user is the owner and if their account is active Or if they are a superuser And the object is not private to a different user Or they are a member of the assigned group Problem is that when I add this logic to the permissions classes of the ModelApiViewset, it returns every project. How do I get it to show only the ones that meet the above criteria? To further illustrate the example, I have 2 accounts right now: my superuser, and a test_user. test_user is not an admin or staff account, and is not part of the manager group. The test_user account is an owner of project 2, but not project 1. But if I use the test_user credentials, I see both project 1 and 2: [ { "id": 1, "name": "Test Private Project", "slug": "test-private-project", "description": "Just testing the super private project", "group": { "name": "manager", "id": 1 }, "created_date": "2020-04-20T18:04:20.666564Z", "modified_date": "2020-04-20T18:04:20.666594Z", "owner": { "username": "admin", "full_name_display": "Administrator", "photo": null, … -
Why I cannot update my heroku app via gitlab CI
I have started messing around with Heroku docker and Django. I have followed the instructions of a tutorial and everything works great. My app is on Heroku, but I cannot update my App. According to the tutorial, when I push my new code to Gitlab the pipeline is run and it deploys the new code to my app in Heroku. Although the pipeline passes nothing changes on my Heroku app, what am I doing wrong? Here is my .gitlab-ci.yml: image: docker:stable services: - docker:dind variables: DOCKER_DRIVER: overlay2 HEROKU_APP_NAME: myapp HEROKU_REGISTRY_IMAGE: registry.heroku.com/${HEROKU_APP_NAME}/web stages: - build_and_deploy build_and_deploy: stage: build_and_deploy script: - apk add --no-cache curl - docker login -u _ -p $HEROKU_AUTH_TOKEN registry.heroku.com - docker pull $HEROKU_REGISTRY_IMAGE || true - docker build --cache-from $HEROKU_REGISTRY_IMAGE --tag $HEROKU_REGISTRY_IMAGE --file ./Dockerfile "." - docker push $HEROKU_REGISTRY_IMAGE - chmod +x ./release.sh And this is the release.sh #!/bin/sh IMAGE_ID=$(docker inspect ${HEROKU_REGISTRY_IMAGE} --format={{.Id}}) PAYLOAD='{"updates": [{"type": "web", "docker_image": "'"$IMAGE_ID"'"}]}' curl -n -X PATCH https://api.heroku.com/apps/"${HEROKU_APP_NAME}"/formation \ -d "${PAYLOAD}" \ -H "Content-Type: application/json" \ -H "Accept: application/vnd.heroku+json; version=3.docker-releases" \ -H "Authorization: Bearer ${HEROKU_AUTH_TOKEN}" Last but not least here are the last messages of the pipeline, as I think that the rest of them are irrelevant to my question.
