Django form field in if statement fail
I'm rendering a Django form using an if statement to construct the html template: {% for field in form %} {% if field.name == 'user_name' or 'phone' or 'email' or 'password1' %} <div class="col-12 col-md-6 col-lg-3"> <p class="text-left m-0 fs-13">{{ field.label_tag }}</p> {% render_field field class="form-control is-invalid" %} </div> {% else %} bla bla {% endif %} {% endfor %} But when I call the template, all fields are constructed using the if statement code, but I have fields like: location, birth_date... that are True in the else statement. What am I doing wrong? -
Overriding Django admin vs creating new templates/views
I am a total noob with Django, I come from the PHP world and I am used to doing things differently. I'm building an app and I want to change the way the backend looks, I want to use Bootstrap 4 and add a lot of custom stuff e.g. permission based admin views, and I was wondering what is the best practice, or how do more experienced django devs go about it? Do they override all the django.contrib.admin templates, or do they build custom templates and login/register next to it, and use the django.contrib.admin only for the superuser? What is the django way? -
Django MimeType error
guys, I have no idea what is wrong with this error. The code is not something that I wrote so I don't know much about it. Any help is greatly appreciated. I will update the question with any other information that you ask for when it is needed. The code is very hard to read an upload to stack overflow so code posts may take a long time to reply.

django image file not found . image name same as directory
In windows system if there is an image file named same as the parent directory name then django server does not show the image file. e.g: http://127.0.0.1:8000/a/a.jpg This url does not give any image. But when the same image is renamed as "b.jpg" http://127.0.0.1:8000/a/b.jpg This url gives the image. Note: This problem exists only when the django server is on windows operating system and browser - chrome. There is no problem with linux. -

AWS DMS migration causes null primary key error
i am using AWS RDS postgres database with django. I migrated the database to a new RDS postgres instance. I am able to connect to it through django and view all the records. But whenever I try to add records lets say new user it gives me # django.db.utils.IntegrityError: null value in column "id" violates not-null constraint # and some times i also get # Primary key (id) duplication error. # i dont understand, django is supposed to handle primary keys (id) and auto increments by default. It is strange why it is passing null while creating new records or why passing those keys which are already in use. I am unable to figure out what is wrong in whole process. It is simple homogenous DMS migration from postgres to postgres. Migration task completes successfully. It shows no errors. All the data and tables with public schema are replicated successfully. But i am unable to add new records to it. Note: I tried migrating db using "pg_dump" command and it worked fine. I was able to add records to it after migration. Also I tried using same postgres engine versions (9.5) on both instances. Any type of help would be … -
Django Channels. Adding users to a Group
I am coding kind of a social network app. I want to have users create conversations and add their friends to the conversation at creation of the conversation. They are going to receive messages via websocket. The problem that I have is that I can add users to listen to their conversations upon establishing websocket connection but how do I add a user's reply_channel to the Group of the newly created by some other user conversation (while the former user already has websocket connection established) so that they could start listening to incoming messages from the conversation? -
Create PostgreSQL Database on another Server using Django
I have a working local environment using Django 1.11 with a PostgreSQL 10 database running on Linux Mint. I am trying to take a copy of this environment and install it on two Ubuntu 16.04 development servers: one for the web server and the other for the SQL server. The problem is running Django with the Ubuntu PostgreSQL server. When I take the Django settings.py file, and change the server from 'localhost' to the IP address of the new PostgreSQL server, every command issued with manage.py fails. This includes createsuperuser, makemigrations and migrate. This fails on both my working, development machine and the new Ubuntu web server. Is there a step I am missing that should be done after changing the database server and before running a manage.py command? Everything I have read says to simply run the makemigrations, and migrate commands. I have even tried to delete the makemigrations folders, but still no luck. Verified: Can connect to the new PostgreSQL server remotely using the same user ID and password, and was able to create a table (so problem should not be related to security or remote access). Here is the (shortened) error that comes up each time: Traceback … -

Styling UserForm in Django
I made a custom user form with fields username, password1 and pasword2, based on UserCreationForm. I want to style it using bootstrap form-control in Meta widgets, but it doesn't work. Is this possible? EDIT Although password1 and password2 are not in Meta fields, they are rendered. The code: class UserForm(UserCreationForm): class Meta: model = User fields = ['username'] widgets = { 'username': TextInput(attrs = { 'class': 'form-control', }), 'password1': PasswordInput(attrs = { 'class': 'form-control', }), 'password2': PasswordInput(attrs = { 'class': 'form-control', }), } -
How to access Postgres database within docker-compose
I'm pretty new to Postgres and Docker, but I am building a webapp with Django that runs inside a docker with a postgresql database. I am trying to view my Postgres database via the command prompt or pgweb. Unfortunately, I can't seem to find the database at all, I tried using the postgres psql terminal commands, but my database wasn't listed inside. My question is, how is the postgresql database stored within a docker-compose container. Do I need to go into the container manually and then view the database? My ultimate goal is to be able to see a list of all my tables and data within the postgresql database. Any documents explaining how the postgresql database interacts with a docker-compose would be appreciated. Thanks! -
Showing multiple views in a single template

Pass a parameter across views - Django
I have the following scenario: I have created globalModels (Season, Team, Player, Referee). Also, I have created seasonalModel (SeasonTeam, SeasonPlayer, SeasonReferee) as I want to record statistics from a Team every particular season, same with Player and Referee) and also I will aggregate statistics from every SeasonTeam into the globalModel Team. I am building platform for administration. So I have next urls: adminSite.urls url(r'^$', views.homeAdmin, name='homeAdmin'), url(r'^addGlobal/', include('globalModels.urls', namespace='addGlobal')), url(r'^addSeasonal/', include('seasonalModels.urls', namespace='addSeasonal')) globalModels.url url(r'^$', admin_views.addGlobal, name='addGlobal'), url(r'^addSeason/', views.addSeason, name='addSeason'), url(r'^addPlayer/', views.addPlayer, name='addPlayer'), url(r'^addTeam/', views.addTeam, name='addTeam'), url(r'^addReferee/', views.addReferee, name='addReferee') Now, in order not to have to choose the season (foreignKey in every seasonalModel) everytime I want to add a new seasonalModel, I want to make a first step of choosing the season, and then let the administratos choose between adding a seasonalTeam, seasonalPlayer... How would you accomplish this? I have thought about 2 possibilities: FRONT END Display with a list of the seasons registered as divs and with JS get the id that the administrator has click on: {% for season in seasons %} <div id="{{ season.season }}" class="adminButton chooseSeason "> {{ season.season }} </div> {% endfor %} And then pass it inside the url: $(".chooseSeason").click(function (){ var season = $(this).attr('id'); … -

Django use of uuid with postmark templates

virtualenv and virtualenvwrapper "There was a p roblem running the initialization hooks" all of a sudden
So my development environment really hasn't changed for a long time. I am using Bash on Ubuntu on Windows for about a year now. I just apply the regular updates with: sudo apt-get update sudo apt-get upgrade sudo apt-get dist-upgrade Haven't had any issues until last week. When I would workon env and then start up Django, all of these Python errors related to encryption and hashing would come up. Don't really remember what they said, but apparently couldn't find something. I just ignored them because I am in the middle of a project and figured I'd address them later since it is just the dev server. Anyway, I come in yesterday to work and all of a sudden I am getting: -bash: /usr/local/bin/python3.6: No such file or directory virtualenvwrapper.sh: There was a problem running the initialization hooks. If Python could not import the module virtualenvwrapper.hook_loader, check that virtualenvwrapper has been installed for VIRTUALENVWRAPPER_PYTHON=/usr/local/bin/python3.6 and that PATH is set properly. I read a number of SO questions related to this. Basically they all suggested to uninstall virtualenv, virtualenvwrapper, and pip. That is if doing pip3 install --upgrade virtualenvwrapper didn't work, which it didn't. Uninstalled, reinstalled, and left work yesterday with … -
django's get_user_model() only in 1.11 during import time
I've created this draft of a reusable app: django-separate-users. It basically works :) But, this code only runs on django 1.11+. The problem is right here, the call to get_user_model(): models.py.

Django authentication how to log in the user to their project
If a user has multiple projects under their account, how do I authenticate the user so that the content is not only specific to their account, but to their default project. Ideally, the project is right at the top portion of the page, inside the base template of the site, right beside the sign-out link. The user should be able to just change the project without signing out and signing back in. The request object should be loaded with the project, so I could query the contacts model like this: Contact.objects.filter(project = request.project) Currently, I have to do the same query like this: user_project = Project.objects.get(user = request.user, project_name = 'summer') Contact.objects.filter(project = user_project) A little nudge in the right direction is much appreciated -
