Why is my individual Tweet ID number changing last few digits to "0" when retrieving tweets though Tweepy?
Background: I'm using Tweepy python library to access the twitter API to retrieve cryptocurrency tweets. My application uses a Django backend and a ReactJs frontend. While my web-app will show the retrieved tweet itself, I intend to also have a clickable link available, to re-route to the original on Twitter. My Django Rest Framework API is retrieving the correct Tweet ID number in full when returning a JSON. However, when I'm retrieving from the Rest Framework API to my Frontend, the last few digits of the Tweet ID number is changed to "0". I wonder if this is a default protection measure that Twitter uses? Thanks in advance for all your help! Please see below for more clarity under "bitcoin_tweet_link": Django Rest API: Front-End of Website: App.js: <div className="center-column-tweet"> <div className="item-row-tweets"> <div className="left"> <span><b>@{tasks.bitcoin_tweet_user}</b><br/><br/>"{tasks.bitcoin_tweet}"<br/><b>Link:</b> https://twitter.com/twitter/statuses/{tasks.bitcoin_tweet_link}</span> </div> </div> </div> -
Django add fields to createsuperuser command
I have several database tables that I use in Django. Now I want to design everything around the database not in the Django ORM but in the rational style of my MySQL database. This includes multiple tables for different information. I have made a drawing of what I mean. I want the createsuperuser command to query once for the user table and once for the residence table. This could then look like this: C:\Users\Project>python manage.py createsuperuser username: input firstname: input lastname: input password: ***** country: input city: input street: input -
How do I validate that a user is at least 13 years old?
I have created a login and registration app in Python for use with Django and I have been using it in a few different projects. My only problem trying to apply it to some projects is I can't figure out how to make sure a user can only register if they are at least 13 years old. This is my models.py and what I have imported for the validations. from django.db import models from datetime import date, datetime import re import bcrypt class User(models.Model): first_name = models.CharField(max_length=100) last_name = models.CharField(max_length=100) email = models.CharField(max_length=150) birthday = models.DateField() password = models.CharField(max_length=200) created_at = models.DateTimeField(auto_now_add=True) updated_at = models.DateTimeField(auto_now=True) objects = UserManager() This is the only validation I have accompanying the birthday input so far. I have other validations, but this is the only one pertaining to birthday. def registration_validator(self, post_data): errors = {} user_birthday = datetime.strptime(post_data['birthday'], '%Y-%m-%d') if user_birthday > datetime.today(): errors["release_date"] = "User birthday must be in the past!" return errors_login My views.py that handles processing the registration. def process_registration(request): errors = User.objects.registration_validator(request.POST) if len(errors) > 0: for key, value in errors.items(): messages.error(request, value, extra_tags='register') return redirect('/') else: first_name = request.POST['first_name'] last_name = request.POST['last_name'] email = request.POST['email'] birthday = request.POST['birthday'] pw_hash = … -
How to solve from django.utils.importlib import import_module ImportError: No module named importlib
Currently I am upgrading my old Django project from django 1.8 to django 1.9 and current my python version is 2.7.12 and i am getting this error File "/home/projectfolder/myproject/local/lib/python2.7/site-packages/social_auth/models.py", line 4, in <module> from django.utils.importlib import import_module ImportError: No module named importlib The same errors i am getting in different paths.For example File "/home/projectfolder/myproject/local/lib/python2.7/site-packages/social_auth/utils.py", line 4, in <module> Now my doubt is should we replace this line - "from django.utils.importlib import import_module " as "from django.utils.module_loading import import_module" in all the paths Or is there any other alternative to get rid of this issue ? -
Make add_action visible to only one model in Django
This is my models.py from app named article from django.contrib import admin from .models import Article, Group from django.contrib import messages class ArticleAdmin(admin.ModelAdmin): def publish_selected_articles(modeladmin, request, queryset): queryset.update(publish_status=True) messages.success(request, "Selected Record(s) Marked as Published") admin.site.add_action(publish_selected_articles, "Publish selected articles") admin.site.register(Article, ArticleAdmin) This code adds action of Publish selected articles to all models. Well, the docs says the same. See here What I want is to have Publish selected articles action button visible only to this this class (i.e. ArticleAdmin). I could also use disable_action as docs shows. I have 5 action buttons and about 10 Apps. So writing disable_action about 50 times does not seem to be a good idea. And what if I some other developer develops more apps in future. Is there a easy solution for this? How can I make add_action visible to specific class in Django model ? Any help is appreciable. Thanks in advance. -
Why django remove GET params from Url? [closed]

Django Template comparing two lists of equal size
I have two lists of equal sizes like so: change_list = ['none', 'M', 'D', 'none] print_list = ['examples', 'app.py', 'list.fr', 'template'] I pass them through the view and I need to know what the value is on the first list so I can display the elements of the second one with a different color according to what's on the first list. For example, I need to display 'app.py' as orange in the template due to the 'M' in the first list. I've searched around and I have no idea how to do this. I tried to pass the len of the list as a range to the view like this: {% for i in len%} {% if changes_list.i == "M" %} <p style="color:orange;"> {{print_list.i}}</p> {% endif %} {% endfor %} But it didn't work. I'm not sure if I formulated the question correctly but I wasn't exactly sure how to explain this. Thank you in advance. -

How Does Django Manager Orchestrate QuerySet?
This is a follow-up question from this post. For the sake of completeness and self-containment, I will include all necessary bits in this question. Consider a very simple example: # Models class Cart(models.Model): name = models.CharField(max_length=20) class Item(models.Model): name = models.CharField(max_length=20) cart = models.ForeignKey(Cart, on_delete=models.CASCADE) # Execution class Test(TestCase): @classmethod def setUpTestData(cls): # Save a new cart c = Cart(name="MyCart") c.save() # Save two items to the cart t = Item(name="item1", cart=c) t.save() Item.objects.create(name="item2", cart=c) def simpleTest(self): i = Item.objects.get(id=2) # <--- breakpoint # Do something, but not important for this question I am using PyCharm to try to understand the inner workings of Django. If we put a breakpoint at the marked line and step into the method call get(). After we get a Manager from __get__ in ManagerDescriptor (due to .objects), the execution now goes to this class method in BaseManager: @classmethod def _get_queryset_methods(cls, queryset_class): def create_method(name, method): def manager_method(self, *args, **kwargs): return getattr(self.get_queryset(), name)(*args, **kwargs) # <--- Starts here manager_method.__name__ = method.__name__ manager_method.__doc__ = method.__doc__ return manager_method The execution stops at the marked line above. If we step into it, get_queryset() is first called, which returns a new QuerySet object, as expected. Note that the new QuerySet … -

Merge two redundant models in Django
I'm working on an online shop at the moment. The shop is written in Django, and was programmed by another person, so I spent days trying to make sense of what he did. At the moment the shop sells only two articles, on two different pages (meaning they have to be bought separately), so the shop is heavily oriented towards this situation. The problem is, the shop's owner expressed his interest in selling everything in one page in the near future, and in adding more products. And that's where my problems start. The model structure was something like this (extremely simplified): class Category1(BaseModel): name = models.CharField(max_length=32) class Category2(BaseModel): name = models.CharField(max_length=64) class Price1(BaseModel): category = models.ForeignKey(Category1, on_delete=models.CASCADE) price = models.DecimalField(max_digits=16, decimal_places=2) currency = models.CharField(max_length=3) class Price2(BaseModel): category = models.ForeignKey(Category2, on_delete=models.CASCADE) price = models.DecimalField(max_digits=16, decimal_places=2) currency = models.CharField(max_length=3) class Order1(BaseModel): [personal information fields] class Order2(BaseModel): [personal information fields] class Article1(BaseModel): price = models.ForeignKey(Price1, on_delete=models.CASCADE) order = models.ForeignKey(Order1, on_delete=models.CASCADE, related_name='articles') class Article2(BaseModel): price = models.ForeignKey(Price2, on_delete=models.CASCADE) order = models.ForeignKey(Order2, on_delete=models.CASCADE, related_name='articles') There is much more than this, of course, but this should be enough to show the relationships between the models. The complete structure of course makes more sense than this one. … -
Bootstrap modal not showing (taken from the official website) using Django
I have the following HTML code in Django template. I used the example from Boostrap website to create a button that shows a modal ,however, when I press the button, nothing happens. I'm not sure why nothing happens and also no error shows in the console. My 'static' folder contains: bootstrap.min.css and bootstrap.min.css.map. <!doctype html> <html lang="en"> <head> {% load static %} <meta charset="utf-8"> <meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no"> <link rel="stylesheet" href="{% static "css/bootstrap.min.css" %}" integrity="sha384-MCw98/SFnGE8fJT3GXwEOngsV7Zt27NXFoaoApmYm81iuXoPkFOJwJ8ERdknLPMO" crossorigin="anonymous"> <title>Dashboard</title> </head> <body> <nav class="navbar navbar-expand-lg navbar-light bg-light"> <a class="navbar-brand" href="/"><img src="{% static "img/logo.png" %}" style='max-width:100px'></a> <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarNavAltMarkup" aria-controls="navbarNavAltMarkup" aria-expanded="false" aria-label="Toggle navigation"> <span class="navbar-toggler-icon"></span> </button> <div class="collapse navbar-collapse" id="navbarNavAltMarkup"> <div class="navbar-nav"> <a class="nav-item nav-link" href="{% url 'admin:logout' %}?next=/" tabindex="-1" aria-disabled="true">Instances</a> </div> </div> </nav> <!-- Button trigger modal --> <button type="button" class="btn btn-primary" data-toggle="modal" data-target="#exampleModal"> New Instance </button> <button type="button" class="btn btn-danger">Delete Instance</button> <!-- Modal --> <div class="modal fade" id="exampleModal" tabindex="-1" role="dialog" aria-labelledby="exampleModalLabel" aria-hidden="true"> <div class="modal-dialog" role="document"> <div class="modal-content"> <div class="modal-header"> <h5 class="modal-title" id="exampleModalLabel">Modal title</h5> <button type="button" class="close" data-dismiss="modal" aria-label="Close"> <span aria-hidden="true">&times;</span> </button> </div> <div class="modal-body"> This is a test! </div> <div class="modal-footer"> <button type="button" class="btn btn-secondary" data-dismiss="modal">Close</button> <button type="button" class="btn btn-primary">Save changes</button> </div> </div> </div> </div> </body> </html>
