Iam trying to save data from my forms to my database but somehow it is not happening. I have created forms in one of my apps which my admin uses.I am new to Django and any help would be greatly appreciated.

Django: Distinct Users Filtering
I'm trying to build a messaging app. Here's my model, class Message(models.Model): sender = models.ForeignKey(User, related_name="sender") receiver = models.ForeignKey(User, related_name="receiver") msg_content = models.TextField() created_at = models.DateTimeField(auto_now_add=True) This is what I tried in view, data = Message.objects.filter(Q(sender=request.user) | Q(receiver=request.user)) In the template, {% for abc in data %} {{ abc.receiver }} <br/> {% endfor %} Here i wants to filter the distinct receivers and re-order them based upon the fact that to whom request.user sent new message recently (as we see on social media platforms). How can I do that? I'm hanged with this code from 1 month, I will be very thankful with every little help :) -

Django-Rest-Auth authentication issue
I have created REST API using Django Rest Framework and used django-rest-auth for auth endpoints. I've also TokenAuthentication to secure the API. The problem arises when using APIDOC. I've added apidoc using coreapi. The documentation needs to be protected too. I can't use TokenAuth in the browser so I enabled SessionAuthentication. This resulted in login endpoint breaking with CSRF error. So how do I protect the endpoints with just TokenAuth and the documentation with SessionAuth separately? Or can I completely bypass security for login endpoint? -
GAE - Firebase Authentication using Retrofit
I have a Django webserver running on the standard Google App Engine environment. I've decided to use Firebase for authentication the Android application which has to get data using Retrofit from the webserver. public static Retrofit getClient(String baseUrl) { OkHttpClient okHttpClient = new OkHttpClient().newBuilder().addInterceptor(new Interceptor() { @Override public okhttp3.Response intercept(Chain chain) throws IOException { Request originalRequest = chain.request(); String token = FirebaseInstanceId.getInstance().getToken(); Request.Builder builder = originalRequest.newBuilder().header("Authorization", token); Request newRequest = builder.build(); return chain.proceed(newRequest); } }).build(); if (retrofit==null) { retrofit = new Retrofit.Builder() .baseUrl(baseUrl) .client(okHttpClient) .addConverterFactory(GsonConverterFactory.create()) .build(); } return retrofit; } My Retrofit Client is created as shown above. This is called after a user has successfully logged in. I'm able to get the token and add that to the header in the OkHttpClient however on the webserver backend, I get the following error: AttributeError: 'WSGIRequest' object has no attribute 'headers' The Django code is: def index(request): id_token = request.headers['Authorization'].split(' ').pop() claims = google.oauth2.id_token.verify_firebase_token( id_token, HTTP_REQUEST) response_data = {} if not claims: logging.debug('Not Logged in') response_data['message'] = 'Not Logged In' else: logging.debug('Logged In!!!') response_data['message'] = 'Logged In' return JsonResponse(response_data) All I'm trying to do here is check if the authentication works. Any ideas what might be going wrong? Thanks -

Django - Multi Table Inheritance with django admin
I am trying to learn django by creating a blog on my own, and I've tried some real simple steps before, but now I want to make something slightly more complex. Currently, I am thinking of dividing the blogs' 'Stories' into 'Blocks'. My idea is to have two child classes 'TextBlock' and 'ImageBlock', and my current models look like this. class Story(models.Model): writer = models.CharField(max_length=189) title = models.CharField(max_length=189) class Block(models.Model): story = models.ForeignKey(Story, related_name='+', on_delete=models.CASCADE) block = EnumField(choices=[ ('TXT', "text"), ('IMG', "image"), ]) serial = models.IntegerField(default=0) date_created = models.DateTimeField(auto_now_add=True) date_modified = models.DateTimeField(auto_now=True) class TextBlock(Block): type = models.CharField(max_length=128, blank=True, null=True, default='paragraph') content = models.TextField(blank=True, null=True) class ImageBlock(Block): src = models.URLField() type = models.CharField(max_length=128, blank=True, null=True, default='full') title = models.CharField(max_length=189, blank=True, null=True) photographer = models.CharField(max_length=128, blank=True, null=True) What I'd like to do now is to create blog entries from the django admin interface. Is it possible to create both types from the main Block? Or do I need to go to both TextBlock and ImageBlock? Any ideas on how I should proceed from here? Thanks. -

How to dynamically add EC2 ip addresses to Django ALLOWED_HOSTS
We've recently changed our deployment strategy to use AWS auto scaling group. One problem we have in production is the new created EC2s, our Application starts to return Invalid HTTP_HOST header: <ip_address>. You may need to add <ip_address> to ALLOWED_HOSTS` because these EC2s are not in the original Django ALLOWED_HOSTS. But it doesn't make sense for each EC2 newly created we have to redeploy, that loses the sense for "auto scale". And we don't want to use wildcards or IP range for security reasons. -

Where I can serialize the object, is in the serializers or views ? and how to do with that? -

Health App : Data saved for a specific patient is being shown in detail view for other patients.
In my health app I am attempting to allow the user to enter patient symptom data and save it. My app contains Identity, Symptom, and IdentitySymptom models. A ManyToManyField exists between the Identity and Symptom. The IdentitySymptom model contains both ForeignKey fields each referencing the Identity and Symptom model. In my views document I used class based views to ensure that each Symptom object I created was attached to a patient. ** PROBLEM ** Each time I save a symptom object data connected to one patient object, that data also shows up in the view of other patient objects. Each nomenclature and descriptionfield should be attached to the patient object for which it was created. However, each time the fields are populated and saved the nomenclature and description seen in all the patients created which is not what I want. Below both Tashoy and Qadi have the same nomenclature and description but I only clicked the Tashoy Beckford anchor tag nomenclature and description How do I ensure that only Tashoy Beckford has that Symptom object data. Essentially I want to ensure the relevant symptoms connect to the relevant patients. Here is the code : models class Identity(models.Model): NIS =models.CharField(max_length = … -
CSV not importing to django models
I'm trying to create a django web app that uses data from CSV's. I've created a django model to house the data from these csv's, I've stored all the csv's in STATIC_ROOT. When I load the page, the called template (datalandingpage.html) loads with no problem. However, when I check django admin, none of the CSVs have been imported. If I were to guess, I think the shortcoming has something to do with django not being able to find the files (though I'm just guessing, I could very well be wrong since I'm a relatively new developer). Below is all the relevant code I've written as an attempt. settings.py: # Static files (CSS, JavaScript, Images) # https://docs.djangoproject.com/en/1.11/howto/static-files/ STATIC_URL = '/static/' STATIC_ROOT = os.path.join(BASE_DIR, 'static/data') models.py: from __future__ import unicode_literals from django.db import models from django.contrib import admin class Data(models.Model): # A bunch of model objects (CharField/IntegerFields mainly) class Meta: verbose_name_plural = 'Data Sets' def __str__(self): return self.someobject views.py: from __future__ import unicode_literals from django.conf import settings from django.shortcuts import render, render_to_response from django.template import RequestContext from .models import Data import csv import os def landing(request): # Opens all csv files in specified directory directory = os.path.join(settings.STATIC_ROOT) for files in os.walk(directory): for … -
DisallowedHost error using PythonAnywhere
I'm new to Python and Django, and I'm following this tutorial to learn some Django basics. I keep getting a DisallowedHost error. (Screenshot: https://ibb.co/c1beYG) As per this post, I added 'chocoberrie.pythonanywhere.com' to the ALLOWED_HOSTS list in settings.py, and I made sure to include it in quotation marks and keep the brackets. I even added it to requests.py, at line 113 (indicated in the error message). Additional screenshots: https://ibb.co/jwUNnb and https://ibb.co/fbmrfw I also committed the changes to Git, and I double-checked the repository to make sure that the URL was added to ALLOWED_HOSTS. I also made sure to reupload the changes on PythonAnywhere. After all that, I'm still getting the error! It's really frustrating, and I don't know what else to do. Any help would be much appreciated! Note: I did see a way to "disable" this error in this post, but I'm using a newer version of Django, so I don't know how to apply this. -
How to order django model by foreign key image title alphabetically
I have model that I need to be able to order in the admin panel alphabetically by the title of the image foreign key. Currently with the code below the models get ordered by when the associated 'logo' images were added to the database, as opposed to by the titles of the associated 'logo' images. class Client(models.Model): logo = models.ForeignKey( 'wagtailimages.Image', null=True, blank=True, on_delete=models.SET_NULL, related_name='+', ) homepage_visible = models.BooleanField(default=True) panels = [ MultiFieldPanel([ ImageChooserPanel('logo'), FieldPanel('homepage_visible'), ], heading='Client information'), ] def __str__(self): return self.logo.title class Meta: verbose_name = 'Client Logo' verbose_name_plural = 'Client Logos' ordering = ['logo'] -
Django - MySQL: 1045 Access Denied for 'user'@'localhost'
I have a Django app using a MySQL database. I created a database foo, then created a new user foo_user, granted all privileges on foo.* to foo_user, and flushed privileges. I can log in from the command-line as foo_user and SHOW GRANTS; which gives me this: +-----------------------------------------------------------+ | Grants for foo_user@localhost | +-----------------------------------------------------------+ | GRANT USAGE ON *.* TO 'foo_user'@'localhost' | | GRANT ALL PRIVILEGES ON `foo`.* TO 'foo_user'@'localhost' | +-----------------------------------------------------------+ I can connect from Python using this snippet: import MySQLdb try: db = MySQLdb.connect('localhost', 'foo_user', 'verysecurepassword', 'foo') cursor = db.cursor() cursor.execute('SHOW GRANTS;') results = cursor.fetchall() for r in results: print(r) except MySQLdb.Error as e: print(e) This prints the privileges for foo_user as one would expect. settings.py db_pass = '' db_pass_file = os.path.join(os.path.expanduser('~'), 'db.passwd') with open(db_pass_file, 'r') as dbpf: db_pass = dbpf.read() DATABASES = { 'default': { 'ENGINE': 'django.db.backends.mysql', 'NAME': 'foo', 'USER': 'foo_user', 'PASSWORD': db_pass, 'HOST': 'localhost', 'PORT': '3306', }, } However, when I try to makemigrations I get django.db.utils.OperationalError: (1045, "Access denied for user 'foo_user'@'localhost' (using password: YES)") I've followed the advice of every SO answer I could find. I've dropped databases and users and then recreated them several times. I can't find anything obviously wrong with it and … -
Internal server error when set cookie in Django
In URL maybe additional parameters for example like utm_campaign In view i get this parameters: utm_campaign = request.GET.get('utm_campaign',None) But when i wanna set this information in cookie i get Internal Server Error without traceback or another information I was trying several solution: response.set_cookie('utm_campaign',utm_source) response.set_cookie('utm_campaign',utm_source.encode('utf-8')) response.set_cookie('utm_campaign',utm_source.encode()) response.set_cookie('utm_campaign',request.GET.get('utm_source')) What is the problem?

Image paths in Django view are relative to directory instead of MEDIA_URL
I've been struggling with this problem for a few days and unable to solve it on my own. I am working on a blog site. The post view is rendered at a URL such as this: domain.com/blog/specificpost/ I have an ImageField in my model. The images upload properly and I can address the images at the correct URLs. domain.com/media/asset.jpg In my settings.py I have defined the media paths. When I access the image files from the Admin, they work properly. MEDIA_ROOT = os.path.join(BASE_DIR, 'media') MEDIA_URL = '/media/' When rendering the view of the post, the image path is rendered incorrectly in the DOM. It is: domain.com/blog/media/asset.jpg It should be: domain.com/media/asset.jpg In my urlpattern I have appended: + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT) and added the relevant imports to urls.py. I believe this code is supposed to serve the files at the domain root during development. I have tried all the solutions here, but the image URLs still render relative to the directory. Any help to set me on the correct path would be useful, thank you very much. -
TypeError : 'manuscript' is an invalid keyword argument for this function
In my health app I am attempting to allow the user to enter patient symptom data and save it. My app contains Identity, Symptom, and IdentitySymptom models. A ManyToManyField exists between the Identity and Symptom. The IdentitySymptom model contains both ForeignKey fields each referencing the Identity and Symptom model. In my views document I used class based views to ensure that each Symptom object I created was attached to a patient. Problem : Each time I created a Symptom object and click to save it, it returns this error : Traceback: File "/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/site-packages/django/core/handlers/exception.py" in inner 41. response = get_response(request) File "/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/site-packages/django/core/handlers/base.py" in _get_response 187. response = self.process_exception_by_middleware(e, request) File "/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/site-packages/django/core/handlers/base.py" in _get_response 185. response = wrapped_callback(request, *callback_args, **callback_kwargs) File "/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/site-packages/django/views/generic/base.py" in view 68. return self.dispatch(request, *args, **kwargs) File "/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/site-packages/django/views/generic/base.py" in dispatch 88. return handler(request, *args, **kwargs) File "/Users/iivri.andre/vision_Map/iivri/script/views.py" in post 115. medical_key = IdentitySymptom.objects.create(patient = patient, manuscript = manuscript) File "/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/site-packages/django/db/models/manager.py" in manager_method 85. return getattr(self.get_queryset(), name)(*args, **kwargs) File "/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/site-packages/django/db/models/query.py" in create 392. obj = self.model(**kwargs) File "/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/site-packages/django/db/models/base.py" in __init__ 573. raise TypeError("'%s' is an invalid keyword argument for this function" % list(kwargs)[0]) Exception Type: TypeError at /script/medical-document/O910231/ Exception Value: 'manuscript' is an invalid keyword argument for this function I …
