Django Crispy Forms / Adding my own classes
I want to change the design of crispy form field with my own classes. I read some information about it but could no find the solution. Let me add my files and explain: forms.py from django.contrib.auth.forms import UserCreationForm from django.contrib.auth.models import User from django import forms from django.core.exceptions import ValidationError class UserRegisterForm(UserCreationForm): ...some code... email = forms.EmailField(label='İTÜ Maili') class Meta: model = User fields = [...'email'] widgets = { 'email': forms.EmailInput(attrs={'class': 'myClassName'}), } This is how I wanted to add my class to email field. register.html <div class="container-fluid mt-5"> <div class="row justify-content-center text-center"> <div class="col-4"> </div> <div class="col-4"> <form class="mt-5" id="registerForm" method="post"> {%csrf_token%} {{ form.email|as_crispy_field }} <button type="submit" value="SIGN UP" class="button is-secondary">Submit</button> </form> </div> <div class="col-4"> </div> </div> </div> This is my template. I added background-color:black; to my css class to check whether it works, but unfortunately it did not work. I tried to write the template with labels and inputs but messed up with validation errors and etc. Is there any way doing this only using crispy form code like I have written: ({{ form.email|as_crispy_field }}) -
Using Jinja2 MemcachedBytecodeCache With Django
I apologize if this answer is obvious, but I can't seem to figure out how to enable Jinja2's MemcachedBytecodeCache in Django (I'm using version 3.0, but generally either). Jinja's documentation makes it sound like it a relatively straightforward setting: class jinja2.MemcachedBytecodeCache(client, prefix='jinja2/bytecode/', timeout=None, ignore_memcache_errors=True) This class implements a bytecode cache that uses a memcache cache for storing the information. It does not enforce a specific memcache library (tummy’s memcache or cmemcache) but will accept any class that provides the minimal interface required. The goal, obviously, is to enable Jinja's bytecode caching with Memcached, which is already enabled on my site. Any assistance in implementing this in settings would be much appreciated. Thank you! -
How can I create multiple objects with one view/form in Django
So here's what I'm attempting to do, and if there's a better way, please let me know. I am creating a dating app and am attempting to create a message form that displays once a user has matched with another user. I already have the matching down and the users displaying correctly, but I need this messaging component. This will be in the form of a link beneath the user's profile that my user has matched with. Now, my InstantMessage model has a foreign key to Conversation which should contain 2 members, whom are having a conversation and contains at least one message exchanged between each other . Now, I what I want to do, when a user hits a link to start messaging, to have my code check if there is already a conversation object between the two users, and if so, then use that conversation object pk for my conversation field in Instant Message and then create a form for that. And if there isn't, then I want a conversation object to be created first, and then a message object to be created. I want this all in one view and with one link, so I assume I … -
Django Python: can't open file 'manage.py': [Errno 2] No such file or directory
I'm having the same issue as this question regarding deploying a Django project to Heroku. I've followed the comments to investigate further, but there's no additional feedback from the original poster to finish the conversation. Following on the Mozilla instructions I make it to the heroku run python manage.py step, which returns the error below: Running python manage.py migrate on ⬢ fast-oasis-14644... up, run.2316 (Free) python: can't open file 'manage.py': [Errno 2] No such file or directory Following the comment from Chris in the referenced question, I ran heroku run bash to get a shell on a one-off dyno. Looking at the structure there, the manage.py file is two levels down in the clmp folder, which is the name of my Django app. ~ $ ls Procfile README.md requirements.txt runtime.txt src ~ $ cd src ~/src $ cd clmp ~/src/clmp $ ls assets clmp contracts manage.py templates I'm assuming that this means something is misaligned with what Heroku is looking for vs my Procfile setup, but I've used web: gunicorn clmp.wsgi --log-file - following on the Mozilla instructions referenced above. My git push to Heroku master is successful. Thanks in advance for the help. -
Counting number of records in database: Django
I'm trying to output the count of the number of "subscribers" in my database in Django, I've found count in my view and then I think I'm using it correctly in the html, but it always just outputs "there are subscribers" without the number, when I use "|length" in the html it always outputs 0, so I'm not sure what my error is. views.py def list_todo_items(request): context = {'todo_list' : Todo.objects.all()} count = Todo.objects.count() context2 = {'count': count} # context = {'count': Todo.objects.count()} # count = Todo.objects.count() return render(request, 'index.html',context,context2) def insert_todo_item(request: HttpRequest): todo = Todo(content=request.POST['content']) try: todo.full_clean() except ValidationError: # pymsgbox.alert('ValidationError!

Up to 15 digits allowed.', 'Title') return redirect('/main/list/') todo.save() return redirect('/main/list/') def delete_todo_item(request,todo_id): todo_to_delete = Todo.objects.get(id=todo_id) todo_to_delete.delete() return redirect('/main/list/') index.html {% for todo in todo_list %} <li class="list-group-item> {{todo.content}} <form action="{% url 'delete_todo_item' todo.id %}" method="post" class="float-right d-inline"> {% csrf_token %} {{form.as_p}} <button type="submit" class="btn"> <i class="far fa-trash-alt fa-lg text-danger float-right"></i> </button> </form> </li> <li class="list-group-item"> <span class="font-italic">There are {{ count }} subscribers.</span> </li> {% empty %} <li class="list-group-item"> <span class="font-italic">No current subscribers.</span> </li> {% endfor %} -
Plotting map with python
I am trying to get a map to plot coordinates which i have saved in my csv file using python and have output it to my django site. This is what i'm trying, using the OSM which I found a tutorial on import numpy as np import pandas as pd import matplotlib.pyplot as plt df = pd.read_csv('D:\Desktop\map.csv') g=df.head() BBox = ((g.longitude.min(), g.longitude.max(),g.latitude.min(), g.latitude.max()) > (116.0561,116.1235,5.9611,5.9981) fig, ax = plt.subplots(figsize = (8,7)) ax.scatter(df.longitude, df.latitude, zorder=1, alpha= 0.2, c='b', s=10) ax.set_xlim(BBox[0],BBox[1]) ax.set_ylim(BBox[2],BBox[3]) ax.imshow(plt.imread('D:\Desktop\map.osm'), zorder=0, extent = BBox, aspect= 'equal') However im getting an error, invalid syntax on fig. Please give me any other suggestions of how to implement this (plotting coordinates on a map and also having it output to a django site) -
Django prevent data from passing in URL
I am new to Django and web dev. I am currently working on a textbox that a user will input data. Then they will click submit and I want that data to go to another page. However when they click the submit button, all the text ends up in the URL. The amount of text that will be passed in this text area is going to be thousands of characters. Is it possible to not allow it to appear in the url? This is my textbox and submit button: <form action="{% url 'parsed' %}"> <textarea name="fulltextarea" cols=40 rows=10></textarea> <br /> <input type="submit" value="Submit"/> </form> urls.py urlpatterns = [ path('', views.home, name='jsonparser-home'), path('parsed/', views.parsed, name="parsed") ] views.py def parsed(request): data = request.GET.get('fulltextarea') print(data) return render(request, 'jsonparser/parsed.html', {"json":data}) Now when I enter text into my text box and click the submit button my URL gets the data in it as: http://localhost:8000/parsed/?fulltextarea=wefwefallmydatasubmittedishere Is it possible to remove all of that in the URL? -
How to post a list of objects containing file input with Axios post and Django
I want to create a web app that allows users to upload a list of files with an associated file name that the user chooses. I want my POST to look as below. {"user": "ME", "files": [{"file":"InMemoryFileUpload", "name": "file_name"}, {"file":"InMemoryFileUpload", "name": "file_name1"}]} I cannot find a way of extracting the files from the POST for this particular use case. I can extract the elements from the list if there are no file objects, and I can extract files if they are not stored in a list. Here is my simplified React script import React, { Component } from "react"; import axios from "axios"; class SomeForm extends Component { handleSubmit(e) { e.preventDefault(); const user = '3' const selectedFile = e.target.input.files[0]; const selectedKey = e.target.keyName.value var formData = new FormData(); formData.append('user', user) formData.append('files', [{'name': selectedKey, 'file': selectedFile}, {'name': 'TEST', 'file': selectedFile}]) axios.post("http://localhost:8000/api/handle_user_input/", formData) } render(){ return( <form onSubmit={this.handleSubmit}> <label>Upload File:</label> <input type="text" name="keyName" /> <input type="file" name="input" /> <button type="submit">Upload</button> </form> ); } } export default SomeForm; The request POST.data is like below <QueryDict: {'user': ['3'], 'files': ['[object Object],[object Object]']}> How can I POST the files correctly in this format? Also, this is my first Django project so any other feedback is … -
HTTP Error 403 on pafy package for python
I have a Django app in which I am using pafy. It worked perfectly fine until today. Now when I try to play a song I get this error: Access to r1---sn-uxaxiv0nxx5q-nv4l.googlevideo.com was denied The page also says "HTTP ERROR 403". The thing is that I haven't changed anything in my code to get this error. What can be causing this?

How to resize images with Django when uploading to AWS S3?
I am uploading and storing my media files on DigitalOcean Spaces (which is built on AWS) with Django using the Boto 3 package. Everything works fine and I am able to view my images on my site, however, I get an error when trying to modify the image using Pillow on upload. I would like to convert the images to JPEG and resize and optimize them. This is how my model's current save function looks: def save(self, *args, **kwargs): super().save(*args, **kwargs) if self.image: img = Image.open(self.image.path) if img.mode != 'RGB': img = img.convert('RGB') if img.width > 100: ratio = img.width / img.height height = 100 / ratio output_size = (100, height) img.thumbnail(output_size) img = ImageOps.exif_transpose(img) img.save(self.image.path, optimize=True, quality=90, format='JPEG') If anyone can help me, I would really appreciate it! -
How to add disable attribute to a Django <select> form?

Aborting long running request in Django
I want to abort a request to an API which takes longer than 5 seconds. I know the client-side code can have a timeout of 5 seconds and that will ensure it doesn't wait any longer than that to get a response, but the Django server would still be processing the request even though the client won't be receiving it at the end. As far as I know, even if I configure this on nginx or gunicorn, those will still act as clients for the Django server app and the same problem will occur - that nginx will not wait for more than 5 seconds, but Django will continue processing the request. Is there any way I can somehow abort this request processing in Django (application server code level) itself? -

Safest and driest way to filter query_set depending on some user info
I have a Post model with a boolean field, is_draft. If the user is logged and is member of the staff, then I want to displays all posts; otherwise, only the posts for which is_draft is false. My first thought was to use a custom model manager and use request.user as following: class PostManager(models.Manager): def get_queryset(self): if request.user and request.user.is_staff: return super().get_queryset() else: return super().get_queryset().filter(is_draft=False) but request is not available in the model. I saw some people use a middleware to access the user in the model. It seems to me the safest way to address my need (ie it's done once, in the custom manager; people modifying the views.py don't have to bother, no risk of forgetting it) but this solution seems controversial. I have of course the possibility to add some logic in the view, but I feel this is not DRY (as I query Post many times) nor safe (risk somebody forgets it at some point). According to you, what would be the cleanest and safest way to address this need? PS: I've found a similar question for which a solution was proposed for Class-based views, but my views are function-based. Thanks a lot! -

Django-oscar less css

Django Jinja - If an object in all objects has attribute run html
I'm needing help figuring out how to write code for this problem (in title). Let's say I have this model: from django.db import models class Section(models.Model): name = models.CharField(max_length=20) display = models.BooleanField(default=True) and I create 2 objects with different names and 2 different display variables: >>> s1.display True >>> s2.display False Here I have some HTML code with Jinja templating for this code to display, if these objects even exist: <!-- In Views, Section.objects.all() is 'sections' --> {% if sections %} <div class="all-sections"> <h2 class="title">Explore</h2> {% for section in sections %} <div class="section"> <p class="section-title">{{ section.name }}</p> </div> {% endfor %} </div> {% endif %} Now I make both of them false: >>> s1.display = False >>> s1.save() Now, if ALL OF THEM HAVE DISPLAY FALSE I don't want the entire section to be there, the same as if there weren't any in that list at all. I've thought about doing a for loop and iterating through each one, but then that would just repeat the all of the HTML code for each one that did have display on. <!-- Wouldn't Work Example --> {% if sections %} {% for section in sections %} {% if section.display %} <div class="all-sections"> … -
Django Update view saving but not updating
I have made a working form to post reviews for restaurants. When user is logged in he can see displayed under his post the edit button. When I use the Updateview however, it doesn't edit, but instead creates a new line in which the new review appears (and that new line doesn't appear then on my webpage). Here is the model: class UserReview(models.Model): # Defining the possible grades Grade_1 = 1 Grade_2 = 2 Grade_3 = 3 Grade_4 = 4 Grade_5 = 5 # All those grades will sit under Review_Grade to appear in choices Review_Grade = ( (1, '1 - Not satisfied'), (2, '2 - Almost satisfied'), (3, '3 - Satisfied'), (4, '4 - Very satisfied'), (5, '5 - Exceptionally satisfied') ) restaurant = models.ForeignKey(Restaurant, on_delete=models.CASCADE) user_review_grade = models.IntegerField(default=None, choices=Review_Grade) # default=None pour eviter d'avoir un bouton vide sur ma template user_review_comment = models.CharField(max_length=1500) posted_by = models.ForeignKey(User, on_delete=models.DO_NOTHING) def get_absolute_url(self): return reverse('restaurants:reviews', args=[self.id]) def get_edit_url(self): return reverse('restaurants:edit-review', args=(self.id,)) Here is the update form (similar as review form): class EditReviewForm(forms.ModelForm): class Meta: model = UserReview fields = [ 'restaurant', 'user_review_grade', 'user_review_comment' ] widgets = { 'restaurant': forms.HiddenInput, 'user_review_grade': forms.RadioSelect, 'user_review_comment': forms.Textarea } labels = { 'user_review_grade': 'Chose a satisfaction level:', … -
Use Matplotlib on django site
I am thinking of starting a new django project for plotting stock prices and displaying them onto the site. I know matplotlib pretty well and was wondering if I could plot the chart and somehow push it to the site with the usual matplotlib features like zoom etc. I have seen this done where that images are pushed but I am wondering if I could push the chart with its functionality provided by matplotlib and I can't seem to find an answer anywhere so maybe it isn't possible? -
