Django Form Classes sometimes they don't appear?
This is the form below. Sometimes my form-control doesn't appear? I've used JQuery hasclass to check and add it if it fails. I just want to know why as my other forms are the same and work fine? Can't seem to figure out what the issue is. If anyone knows please let me know :) class holder_password_update_form(PasswordChangeForm): def __init__(self, user, *args, **kwargs): self.user = user super().__init__(user, *args, **kwargs) self.base_fields['old_password'].widget.attrs['class'] = 'form-control' self.base_fields['new_password1'].widget.attrs['class'] = 'form-control' self.base_fields['new_password1'].help_text = mark_safe('<p class="text-start" style="padding-left: 10px"> Your password can\'t be too similar to your other personal information, can\'t be a commonly used password, must contain at least 8 characters, 1 uppercase letter, 1 lowercase letter, 1 digit(s), 1 special character. </p>') self.base_fields['new_password2'].widget.attrs['class'] = 'form-control' self.base_fields['new_password2'].help_text = mark_safe('<p class="text-start" style="padding-left: 10px">Enter the same password as before, for verification.</p>') def save(self, commit=True): password = self.cleaned_data["new_password1"] self.user.set_password(password) if commit: self.user.save() return self.user -
Can you make a Django form dropdown box accept a model as its choices?
I have a real estate site where I am trying to be able to upload multiple photos to one 'property' without going through the django admin panel (so I can multi select photos.) Current view for custom built form I am able to choose multiple files, upload them to my 'uploads' folder and able to see them in the admin panel for databases. The issue is that the property name from the form I built doesn't connect the Property object to the Property Photos objects. Its just a null value. When I click on a Property Photo object only then does it assign the Property object to it. Property Photo objects BEFORE Property Photo object Once I click on it and push save Property Photo object After How do I get to be able to select (using a dropdown) a Property object from all my Property objects as a list and assign those photos uploaded to that Property object? Below are my: html form, models.py, views.py, and forms.py photo_upload.html <body> <form action="" method="POST" enctype="multipart/form-data"> {% csrf_token %} <div class="fs-1">Photo Upload</div> {{ image_form }} <button>Upload</button> </form> </body> models.py class Property(models.Model): class Meta: verbose_name_plural = 'Properties' address = models.CharField(max_length=150) slug = models.SlugField(unique=True, … -
Is it possible to have an input from a form in a html template be added to the url in a django project?
In the sidebar of my homepage, there is a search box where a user is meant to be able to type in the name of an entry and be taken to that page. So for example, if they type in css they would be taken to http://127.0.0.1:8000/wiki/css where the value inputted is appended to the url. (The home page url is http://127.0.0.1:8000/wiki/.) When I use the get method in the form it ends up searching up /wiki/?q=css instead of just having /css at the end of the url. However, when I use the post method in my form the url remains at http://127.0.0.1:8000/wiki/ with no additional url at the end. How do I append an input to the end of a url? HTML: <h2>Wiki</h2> <form action="/wiki/" method="post"> {% csrf_token %} <input class="search" type="text" name="q" placeholder="Search Encyclopedia"> </form> urls.py: from tokenize import Name from unicodedata import name from django.urls import path from django.http import HttpResponse from . import views urlpatterns = [ path("", views.index, name="index"), path('hello/', views.hello, name='hello'), path('<str:name>', views.entry, name='entry'), path('new/', views.new, name='new'), path('random/', views.randomEntry, name='random') ] views.py: from django.shortcuts import render from django.http import HttpResponse from django import forms import random from . import util def index(request): return render(request, … -

My objects dublicate each other in django template
I'm trying to do my Django web-app and can't to overcome a problem. I need to split my model objects on two divs for correct display, but my dish objects just duplicate each other. I've tried to find info how to split my dishes objects on two parts and give them to html code, but it didn't works. Also there is can be a python templates solution, but I don't know how to resolve it, because the pure html code of project is something I never seen before (there is left-list and right-list classes for dishes columns, therefore we need to split our dishes dict somehow).

Ajax post multiple inputs
I have html input fields with the name personals. I use the [] such that I can have multiple inputs on the same name and post that. Before I was using a normal submit form. And I got it in my Django backend with getlist('personal[]') Everything worked as expected. As information: the codes are not complete. Just the most important lines are shown. My html code before <input type="text" name="personals[]" id="personals[]" placeholder='Email'> <input type="text" name="personals[]" id="personals[]" placeholder='Phone'> My view before def build(request): if request.user.is_authenticated: if request.method == 'POST': name = request.POST.get('name') personals = request.POST.getlist('personals[]') Now I am using Ajax to submit it, without reloading the page. It does not work anymore with personals[] therefore I have changed it too personals just without the parenthesis. The problem is, that personal contains only the first input. But not all the others. It is important to use the same input name (in this case personals) because I use some dynamic input fields, where the users can add more fields. Therefore I don't want to change the name to for example personals1 and personals2. My html code now <input type="text" name="personals" id="personals" placeholder='Email'> <input type="text" name="personals" id="personals" placeholder='Phone'> My view now def build(request): if … -

What Python package to do mapping like Zillow? [closed]

What is the easiest way to do that on a Django server with a React front end? Packages or strategy is deeply welcome. -

I have a django app with tasks stored in a database, similar to a kanban board type layout and each record has a column and order for where they are in the list. The problem is this list can get to hundreds or thousands of records in one column, on changing column based on where the user places the card the column is updated and order is recalculated/set for all records in that column. Is there a more efficient way than a heavy process updating thousands of records to set order? -
Alternative of DISTINCT ON in Sqlite database
Suppose, I got the following model named table ,say |title | author |version | ....| |:-----| :------|:------:|----------- |python| someone| 1.0 | .... | |python| someone |2.0 | .... | |c++ | random | 1.0 | .....| | c | me | 1.0 | .... | |c | me |2.0 | .... | What I want here is a table with no repeating values in the title field . I've tried with table.objects.distinct("title") I came to no that this is only supported in postgress. Is there any alternative of this on sqlite database? -

Why does .save() still take up time when using transaction.atomic()?
In Django, I read that transaction.atomic() should leave all the queries to be executed until the end of the code segment in a single transaction. However, it doesn't seem to be working as expected: import time from django.db import transaction my_objs=Obj.objects.all()[:100] count=avg1=0 with transaction.atomic(): for obj in my_objs: start = time.time() obj.save() end = time.time() avg1+= end - start count+= 1 print("total:",avg1,"average:",avg1/count) Why when wrapping the .save() method around a start/end time to check how long it takes, it is not instantaneous? The result of the code above was: total: 3.5636022090911865 average: 0.035636022090911865 When logging the SQL queries with the debugger, it also displays an UPDATE statement for each time .save() is called. Any ideas why its not working as expected? PS. I am using Postgres.
