How to append a paperclip icon in email body - Gmail
I have integrated Gmail in Python and it's working great. Now I need to append a paperclip icon in the list view of email just like the Jira appends to its emails. (But no physical image is actually attached) . I'm unable to do so in my scenario because there's no physical attachment in my email. So I'm wondering how Jira is doing it. Does anyone get the same scenario? A screenshot is also attached for further clarification. Happy Learning. -

Manytomany field custom display objects in Django
I'm developing a site where I can manually add photographers to the Django adminpanel and then upload the images taken by them. I used the default User system in Django and added a field here that shows this user is a photographer or not : from django.contrib.auth.models import AbstractUser # Create your models here. class User(AbstractUser): is_photographer = models.BooleanField(default=True) Also, in the model that I need to put the images, I used ManyToMany field for photographers (because these photos may have been taken by several people) : from registration import User class Photo(models.Model): ... photographers = models.ManyToManyField(User) The problem is that when adding a new image to the admin panel, users who are not photographers and the is_photographer is False, is also displayed in the Photographers. I want only users who are photographers to be displayed and not normal users. -

Serial request to TokeView of django rest framework social oauth2 causes error
I have mobile backend created with django and I use django rest framework social oauth2 TokenView to refresh access token. from rest_framework_social_oauth2 import views as auth_views urlpatterns = [ path('my-token-path', auth_views.TokenView.as_view(), name = 'my-token-path'), ] The mobile app automatically try to re login when any api request receives Http 401. My mobile app makes several api request at launch. When the app launches and toke was expired, several api requests receives 401 thus each one accesses TokenView to re login using refresh token. When this happens, some requests to TokenView fails with error log saying datbase is locked. How can I prevent this error? -
Django List Based Off Previous List
I am trying to make a dynamic list of choices. That is, the choices change based on a previous answer. For example, if country = ["USA", "Canada", "Mexico"], then click "USA" will generate a list with the 50 US States, state = ["Alabama", "Alaska"]. I tried to do an if statement, however, that did not seem to work. I am not sure what the best option for this is. class Property(models.Model): address = CharField(max_length = 200) city = CharField(max_length = 200) COUNTRY_LIST = [ ("USA", "United States"), ("CAN", "Canada") ] country = CharField(max_length = 3, choices = COUNTRY_LIST) USA_STATE_LIST = [ ("AL", "Alabama"), ("AK", "Alaska"), ("AZ", "Arizona") ] CAN_STATE_LIST = [ ("AL", "Alberta"), ("BC", "British Columbia") ] state = CharField(max_length = 2, choices = ?) -

How to generate form elements from the forms.Form classe in Django?
In my project, a feature has multiple possible scopes. class ProjectForm(forms.Form): features = Feature.objects.all() i = 0 for feature in features.iterator(): scopes = RectificationAssetMultiField( required=False, queryset=Scope.objects.filter(feature=feature.pk), widget=forms.CheckboxSelectMultiple, ) i+=1 class Meta: model = Project I need to create groups of "RectificationAssetMultiField". With my current code, only the last set of scopes are desplayed with {{ form.scopes }}.

How to edit a form field to add some condition using Django template
I have a form (ModelForm, Model and view). Everything works fine but there is a new requirement in the project and one of the text-input is no longer simple, I need to use some Django template (if condition). This is exactly the HTML representation of the input that I need (and it works separately): <input class="form-control ts_project" id="ts_project" name="ts_project" type="text" {% if entry.project %}value="{{ entry.project.id }}: {{ entry.project.name }}"{% endif %}> What I have tried: edit the attributes of the widget in the forms.py so that it looks as close as possible to the HTML code above but it has been impossible for me. forms.py: from django.forms import ModelForm from django import forms from expense.models import Expense class ExpenseForm(ModelForm): class Meta: model = Expense fields = ['project'] widgets = { 'project': forms.TextInput( attrs={ 'class': 'form-control ts_project', 'id': 'ts_project', 'name': 'ts_project', {% if entry.project %} 'value':'{{ entry.project.id }}: {{ entry.project.name }}' {% endif %}, } ) } The code doesn't work but I can't think of another way to make it work. class, id and name working as expected if I delete value and all the Django template code. models.py (truncated): from django.db import models from django.contrib.auth.models import User from project.models … -

Django views not returning a value from a multiple parameter request?
I've been using vanilla Django as a backend to my React frontend. I'm trying to make a POST request using axios that passes a dictionary of 2 values to my django view, and so far on my front end the values are valid, the connection to the django url is made, but the only issue is the actual data being processed in the view. If I try to print the value, it returns as None. Heres what I have so far: Relevant Code views.py def render_data(request): reddit_url = request.POST.get('reddit_url') sort = request.POST.get('sort') print(reddit_url, sort) users_data, count = run_data(reddit_url, sort) data = { 'users_data': users_data, 'count': count, } return JsonResponse(data) component.jsx const APIcall = () => { axios .post( `http://127.0.0.1:8000/reddit_data/`, { reddit_url: location.state.link, sort: location.state.sort, }, { headers: { "Content-Type": "application/json", "X-CSRFToken": location.state.token, }, withCredentials: true, //cors requests } ) .then((res) => { console.log("YESSIR"); setLoading(false); }); }; Expected/actual output Ideally, the output would print the values from the request, but the actual result is just None, None.

Do queries involving tables with geometry that don't query the geometry itself take longer to query than a table without geometry?
I have a postgis table in a geodjango application that contains around 45,000 rows with a multipolygon geometry type. I would like to know if querying this table is slowed by the presence of the geometry when the geometry is not involved in the query, or in other words, if I related the geometry field with a one-to-one relationship would this boost performance? -
