Importing Django module from a subfolder
I have a Django project where in the project's root folder (where manage.py is) I can do (venv) MyName-MacBook:mydjangoproject myname$ python >>> import django >>> from django.core.mail import EmailMessage, send_mail >>> However, when I create a subfolder, this doesn't work anymore (venv) MyName-MacBook:mydjangoproject myname$ mkdir subfolder && cd subfolder (venv) MyName-MacBook:subfolder myname$ python >>> import django >>> from django.core.mail import EmailMessage, send_mail Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/Users/andrasnagy/Documents/drill/venv/lib/python3.6/site-packages/django/core/mail/__init__.py", line 11, in <module> from django.core.mail.message import ( File "/Users/andrasnagy/Documents/drill/venv/lib/python3.6/site-packages/django/core/mail/message.py", line 7, in <module> from email import ( File "/Users/andrasnagy/Documents/drill/email/email.py", line 2, in <module> from django.core.mail import EmailMessage, send_mail ImportError: cannot import name 'EmailMessage' >>> I realise this is a very basic question, but I am a bit stuck. It's strange that I can import django, but not the other functions. -

Formset created with inlineformset_factory doesn't render labels on page

Django ORM group by, and find latest item of each group
Say we have a model as below class Cake(models.Model): baked_on = models.DateTimeField(auto_now_add=True) cake_name = models.CharField(max_length=20) Now, there are multiple Cakes baked on the same day, and I need a query that will return me a monthly cake report which consists of each day of the month, and the names of the first and last cakes baked on that day. For example, if the data is something like this: baked_on cake_name 11 Jan 12:30 Vanilla 11 Jan 14:30 Strawberry 11 Jan 20:45 Avocado 12 Jan 09:05 Raspberry 12 Jan 16:30 Sprinkles 12 Jan 20:11 Chocolate My query's output should look like date first last 11 Jan Vanilla Avocado 12 Jan Raspberry Chocolate How should I go about doing this in a single ORM call? -
Django rest-framework : Unit tests are using the production database
I'm currently working on a small app to learn about Django and Django-Rest-Framework and stumbled across a small issue related to unit testing. I just have two applications in my project : api (which provides a RESTful api to mess around with the DB), and web (which just sends queries to the api and applies a layout to render web pages). Nothing complicated. However, when launching unit tests, those testing the api work as expected and seem to use the temporary DB, but those testing the web application seem to use the production database. Here is my model (api.models) : class User(AbstractUser): country = models.CharField(max_length=32, verbose_name="Country of origin", name="country", blank=True, null=True) phone = models.CharField(max_length=32, verbose_name="Phone", name="phone", blank=True, null=True) field = models.CharField(max_length=32, verbose_name="Field of occupation", name="field", blank=True, null=True) occupation = models.CharField(max_length=32, verbose_name="Occupation", name="occupation", blank=True, null=True) birthdate = models.DateField(verbose_name="Birth Date", name="birthdate", auto_now_add=False, auto_now=False, blank=True, null=True) description = models.TextField(verbose_name="Description", name="description", blank=True, null=True) def __str__(self): return self.username Here is is the web view which causes problems (web.views): def profile(request, usrname): """Handles profile page behaviour and rendering""" stdlogger.info("PROFILE : request for home page") if request.method == "GET": # retrieve single profile stdlogger.debug("PROFILE_get : request for profile of '" + usrname + "' retrieval") r = … -
Bundling python dependencies in the project folder itself so as it can be easily shared and start application without downloading any dependencies
Whenever we download any python dependencies i.e django,MySQL by using 'pip' it get install in the root folder that would be c drive on windows( where we have install python). How can I install this dependencies in my project folder itself, so when I start my application it will read the dependencies from project folder rather from c drive. My purpose is whenever i give my application to user or third person he should directly start application instead of downloading all dependencies. -
multiprocessing django admin command
I have a django-admin command that reads from a database and then loops through the records returned, creates class instances and runs some methods. I would like to run some of these in parallel based on a group key. I've prepared the data so I would have a dictionary of groups with a list of items to process per group. results = {1: [{'id': 1}, {'id': 2}, {'id': 3}, 2: [{'id': 10}, {'id': 11}]} for each group number, 1 and 2, a separate process should be started, passing in the list of dictionaries containing the IDs. The called process will then loop through those IDs in turn. My simplified version of the admin command looks like this: from django.core.management.base import BaseCommand, CommandError import os import time import datetime from booker.models import BookingRequest from booker.automation.booking import Booker from django.conf import settings from itertools import groupby def shrink_dict(booking_dict, remove_list): for i in remove_list: del booking_dict[i] return booking_dict def make_booking_dict(qs): booking_dict = { key: [shrink_dict(b, ['group_id']) for b in group] for key, group in groupby(qs, lambda b: b['group_id']) } return booking_dict class Command(BaseCommand): help = 'Some help text' def add_arguments(selfsel, parser): pass def handle(self, *args, **options): requests = BookingRequest.objects.all() number_requests = len(requests) print('{} … -

Django: Selectively Apply CSS Styles to Quiz Radio Buttons
I have users take a quiz. After each question, I want to show them whether their answer was correct or incorrect. The correct answer should be highlighted in Green, and their answer (if incorrect) should be highlighted in red (using Twitter Bootstrap styles). I am currently rendering the quiz results page in Django and HTML like so: {{ player.question }} <div class="myradio"> <label for="choice_1"><input id="id_1" type="radio" value="q1" disabled/> {{q1}}</label> </div> <div class="myradio"> <label for="choice_2"><input id="id_2" type="radio" value="q2" disabled /> {{q2}}</label> </div> <div class="myradio"> <label for="choice_3"><input id="id_3" type="radio" value="q3" disabled /> {{q3}}</label> </div> <div class="myradio"> <label for="choice_4"><input id="id_4" type="radio" value="q4" disabled /> {{q4}}</label> </div> <b><p>Correct Answer: {{solution}}</p><b> Total Score: {{total_score}} I am storing the solution to the question in {{solution}}. I have been trying to figure out how to selectively apply CSS filters if, for example, {{q1}} == {{solution}} that should be highlighted green. I can grab the participant's answer with {{player.submitted_answer}}, and so want to highlight a div element red if {{player.submitted_answer}} != {{solution}}. I have tried messing around with if statement blocks, but can't seem to get it right. Any ideas? -
error configuring Geodjango on Heroku
I've followed the steps laid out in Heroku to install geoDjango but am running into some obscure errors upon migration. I installed the dj-database-url library, and added the GDAL_LIBRARY_PATH settings to my settings as instructed here. I then got errors asking me to check that GDAL was installed. I searched around stackoverflow and figured I needed a buildpack for geodjango. I only installed this buildpack: https://github.com/cyberdelia/heroku-geo-buildpack and while it solved the initial errors, it now leaves me with this traceback: $ heroku run python manage.py migrate Running python manage.py migrate on ⬢ paup... up, run.6303 (Free) /app/.heroku/python/lib/python3.6/site-packages/daphne/server.py:12: UserWarning: Something has already installed a non-asyncio Twisted reactor.

What's the sequence of middleware execution in django when error occurs in process_request?
I am looking into django middleware codebase. I looked into following diagram So, the diagram is quite clear. But I have some questions What happens when exception comes in process_request() middleware ? How is it handled ? Will the response_middleware be invoked ? Eg. if exception comes in process_view() of AuthenticationMiddleware, then will process_response() of MessageMiddleware be invoked ? What happens when in process_response() middleware returns response? Eg. if process_view() of AuthenticationMiddleware returns respones, then will process_response() of MessageMiddleware be invoked ? OR it'll turn back from AuthenticationMiddleware(ie, it'll invoke process_response() of AuthenticationMiddleware, but will not invoke process_response() of MessageMiddleware) I have debugged the behaviour of django in 1.10 where new style middleware classes are used, but I am not familiar about old MIDDLEWARE_CLASSES settings ? For django 1.10:- 1) If process_request() for AuthenticationMiddleware returns response, then process_template_response() and process_response() will be invoked as show in the figure given below for all the middlewares. 2) If process_request() for AuthenticationMiddleware raises exception, then also the behavior will be the same. Correct me, If I am wrong. Thanks in Advance. -
Django ORM Join on two columns
My models are following: waves/models.py class Assignment(models.Model): week = models.OneToOneField(Week) text = models.TextField() title = models.CharField(blank=True, max_length=255, default="") class Week(models.Model): wave = models.ForeignKey(Wave) ... class Wave(models.Model): name = models.CharField(unique=True, max_length=255) ... class AssignmentSubmission(models.Model): assignment = models.ForeignKey(Assignment) text = models.TextField() date_created = models.DateTimeField() ... waveexceptions/models.py class WaveException(models.Model): user = models.ForeignKey(User) wave = models.ForeignKey(Wave) deadline = models.DateTimeField() comments = models.TextField(blank=True) assignment = models.ForeignKey(Assignment, null=True, blank=True) ... I want to use django ORM to select the data from WaveException and annotate date_submitted which is the date when user from WaveException created AssignmentSubmission record. I did that using raw query: SELECT `waveexceptions_waveexception`.`id`, `waveexceptions_waveexception`.`user_id`, `waveexceptions_waveexception`.`deadline`, `waveexceptions_waveexception`.`comments`, `waveexceptions_waveexception`.`assignment_id`, `waves_assignmentsubmission`.`date_created` AS `date_submitted`, `auth_user`.`primary_key`, `auth_user`.`first_name`, `auth_user`.`last_name`, `waves_assignment`.`id`, `waves_assignment`.`week_id`, `waves_assignment`.`text`, `waves_assignment`.`title`, `waves_week`.`id`, `waves_week`.`end_date` FROM `waveexceptions_waveexception` INNER JOIN `auth_user` ON (`waveexceptions_waveexception`.`user_id` = `auth_user`.`id`) LEFT OUTER JOIN `waves_assignmentsubmission` ON (`auth_user`.`id` = `waves_assignmentsubmission`.`created_by_id` AND `waves_assignmentsubmission`.`assignment_id` = `waveexceptions_waveexception`.`assignment_id`) LEFT OUTER JOIN `waves_assignment` ON (`waveexceptions_waveexception`.`assignment_id` = `waves_assignment`.`id`) LEFT OUTER JOIN `waves_week` ON (`waves_assignment`.`week_id` = `waves_week`.`id`) Similar SQL query is generated with the following code: fields = ['deadline', 'user__first_name', 'user__last_name', 'comments', 'assignment__title', 'assignment__text', 'assignment__week__end_date'] queryset = WaveException.objects.select_related('user').select_related('assignment__week').only(*fields).annotate( date_submitted=F('user__assignmentsubmission__date_created') ) The only difference is that it does not do the join on assignment_id to waves_assignmentsubmission. How can I achieve this using ORM? I am using Python … -

Wildcard search in Django adminsite
am currently working on django. Now, I want achieve the wildcard search, to be more specifically, achieve precise searching using imprecise key words. For example, when I type 'a$c', all the matching results will be 'ac', 'abc', 'a!c', 'Ac', 'AC' and so on. Basically, '$(or maybe other characters)' could be numbers, could be letters or nothing. Is there any method to do this? BTW, my code for achieving the basic search function is written as below: class MetaboliteAdmin(admin.ModelAdmin): search_fields = ['id', 'name', 'compartment', 'charge', 'formula'] class ReactionAdmin(admin.ModelAdmin): search_fields = ['id', 'name','metabolites', 'gene_reaction_rule', 'subsystem'] class GeneAdmin(admin.ModelAdmin): search_fields = ['id', 'name', ''] I learned that I need to override the get_search_result to achieve my goal, but could someone tell me how to code? -

No module named 'raven' - when pushing to heroku
I'm using cookiecutter django. I do recall not setting raven when I initially started a new cookiecutter project, so I think it does make sense that raven was not installed.

Checkboxes to select objects in Django
I have Article model and user wants to select which articles should be exported to file. I want to use Django Form / ModelForm class to generate something like: <input type="checkbox" name="articles[0]">Article #0</input> <input type="checkbox" name="articles[1]">Article #1</input> <input type="checkbox" name="articles[2]">Article #2</input> <!-- ... --> How can I do that and then get selected articles?
