Q: Django Channels on Elastic Beanstalk (aws)
I have a Django(2.0.2) app I deployed successfully to ebs. I implemented websockets with Channels(2.0.2) + Redis(4) and swapped to an Application Load Balancer following this guide: https://medium.com/@abhishek.mv1995/setting-up-django-channels-on-aws-elastic-beanstalk-716fd5a49c4a. Up until recently everything was working just fine but a few days ago I started getting 502 errors when trying to connect to my websockets. failed: Error during WebSocket handshake: Unexpected response code: 502 My supervisor config: [program:daphne] command=/opt/python/run/venv/bin/daphne -b 0.0.0.0 -p 5000 bang.asgi:application directory=/opt/python/current/app user=ec2-user numprocs=1 stdout_logfile=/var/log/stdout_daphne.log stderr_logfile=/var/log/stderr_daphne.log autostart=true autorestart=true startsecs=10 stopwaitsecs = 600 killasgroup=true priority=998 environment=$djangoenv [program:worker] command=/opt/python/run/venv/bin/python manage.py runworker websocket directory=/opt/python/current/app/src user=ec2-user process_name=%(program_name)s_%(process_num)02d numprocs=4 stdout_logfile=/var/log/stdout_worker.log stderr_logfile=/var/log/stderr_worker.log autostart=true autorestart=true startsecs=10 stopwaitsecs = 600 killasgroup=true priority=998 environment=$djangoenv Load Balancer config: option_settings: aws:elbv2:listener:80: DefaultProcess: http ListenerEnabled: 'true' Protocol: HTTP aws:elasticbeanstalk:environment:process:http: Port: '5000' Protocol: HTTP On localhost everything works fine but currently on aws I can't figure out how to get the websockets to work again.

How to maintain form parameters when new url is called
I have a form shown in the first picture below and a set of navpills shown in the second picture. When I click the navpill it calls a url that either ends with 'charts' or 'tables'. Whenever I press the navpill though all the values in the form are cleared to the original template. I need them to stay so when I switch from charts to tables I get the same information. i.e. if there is a fund type selected I want it to still be their if I click on tables when I was previously on charts. I tried using "GET" as such: min_year = request.GET.get('year_min', None) if not min_year: min_year = '2013' But that only works if I submit the form. As soon as I click on one of the values it resets. Here is the html for the "Start Year" box: <h6>Start Year</h6> <div class="form-group"> {{form.year_min|attr:"class:form-control"}} </div> And here is the form: CHOICES = ( ('1998', '1998'), ('1999', '1999'), ('2001', '2001'), ('2002', '2002'), ('2003', '2003'), ('2004', '2004'), ('2005', '2005'), ('2006', '2006'), ('2007', '2007'), ('2008', '2008'), ('2009', '2009'), ('2010', '2010'), ('2011', '2011'), ('2012', '2012'), ('2013', '2013'), ('2014', '2014'), ('2015', '2015'), ('2016', '2016'), ('2017', '2017'), ('2018', '2018'), ) year_min … -

Django chain multiple queries in view
I have three models: Course Assignment Term A course has a ManyToManyField which accesses Django's default User in a field called student, and a ForeignKey with term An assignment has a ForeignKey with course When a user logs in to the page, I would like to show them something like this bootstrap collapse card where I can display each term and the corresponding classes with which the student is enrolled. I am able to access all of the courses in which the student is enrolled, I'm just having difficulty with figuring out the query to select the terms. I've tried using 'select_related' with no luck although I may be using it incorrectly. So far I've got course_list = Course.objects.filter(students = request.user).select_related('term'). Is there a way to acquire all of the terms and their corresponding courses so that I can display them in the way I'd like? If not, should I be modeling my database in a different way? -

HTML in django widgets?
I'm creating a project in Django. I use ModelForms quite a bit to get user data. I'd like to add help text to each of my fields. How I'd like those to appear is like this: A tiny "?" image to the right of the input, then a popup that appears when the "?" is hovered over. I have this working in CSS and HTML. What I need to do is put in an tag before every instance of help_text being displayed, along with some other HTML. From my understanding I can do this by subclassing widgets, but I've seen in several places that I shouldn't add HTML to widgets? It seems much less elegant to stop using the ModelForm auto-rendering in all my templates and instead re-write it using loops and then put the HTML in there. The help_text is never going to be controlled by anyone except me, so I don't believe XSS is a concern. Am I missing something? Is there an easier/better way to do this? Also, if someone could point me to a guide on this with an explanation, it would be much appreciated. -
Why do I get an operational error, saying a database is read-only?
I'm using SQLite with Django, have been for a few months. Today I was about to do replace a table with an updated version, which I regarded as tricky so I took a full backup of my entire project. At a certain point, I started getting this error -- with subtext "attempt to write a readonly database." This made no sense to me, but after trying and failing to fix it, I renamed the entire directory and restored the morning backup. No help. I tried a different browser. No help. I logged in with an incognito session. No help. I logged in with an incognito session and a different Django user account. No help. In all cases, it's the login that fails. And it fails just after I enter the password. The site is still in debug mode, and I've pasted the error info to http://dpaste.com/2NS9ZMJ.txt I have no idea how to get my site working again, if a complete restore of the project directory won't do it. -
Modifying a field in serializers.ModelSerializer Class imported from an external library
I'm trying to override/modify a class XXXSerializer(serializers.ModelSerializer) object defined in an external library that I am including in the installed_apps configuration of my settings.py. class XXXSerializer(serializers.ModelSerializer): username = serializers.CharField(validators=[UniqueValidator(queryset=User.objects.all())]) email = serializers.CharField(validators=[UniqueValidator(queryset=User.objects.all())],default='') class Meta: model = User exclude = [ 'is_superuser', 'is_staff', 'is_active', 'content_type', 'groups', 'user_permissions', 'account_id', ] As shown above, the email is required to be unique in their definition. However, I do not want to require it to be unique. My question is therefore, what is the best way to override this field? Some thoughts/attempts: Copy the entire library directly into my project, and take out the validator there. I think this would definitely work but may not be an optimal solution? Somehow override it by defining another YYYSerializer with my desired property, and use import external_library sys.module['external_library.XXXSerializer'] = YYYSerializer. However, I'm not exactly sure about 1. where to put this piece of code, 2. the proper syntax, 3. whether this would even work in an ideal situation. When I put it in settings.py or some __init__ files, it returns Apps aren't loaded yet error - probably because the external_library hasn't been loaded yet. Any suggestions would be appreciated! -

django import csv in several related models
For a web application of naturalistic data for the study of bats (http://www.dbchiro.org), I need to be able to propose a view allowing to import files from spreadsheets (csv, ods files , xls) into database. To import this data into a single table, no problem, several extensions exist (django-import-export or django-csvimport in particular). On the other hand, my need is more particular because my naturalistic data is distributed in several distinct tables (not counting the tables of dictionaries). Here is the schematic diagram: Model Place Place (a locality is a site with unique x / y coordinates as a building). 1-n Model Session (one data = one date and one inventory method by locality) 1-n Model Sighting (one data = one species per session) 1-n Model CountDetail (one data = 1 detail for a species: eg number of males, number of females, etc.) What I would like to get is the ability to import the data of a session with a single csv file that would populate the last two models: Observations (Sighting) and for each observation (each species observed), its detailed data (CountDetail). Is there one or more simple solutions (I'm doing well but I'm not a great python … -

How to pull a html template on a $.post call, and include data?
I have the following code on one Django HTML template that when it runs it pulls the html from another template and loads it into the #container element. $.get('/form/', function(form){ $('#container').html(form); }); So if I was to follow the same thought process I have this code on another page in which I need to use a POST request instead of GET. $.post( '/form/results/', {item: $('#item-selector').val(), csrfmiddlewaretoken: csrftoken}, function(data){ $('#container').html(data) } ) So what I'm trying to get the post request to do is to pull the html from the url and insert it into the #container element but I can't get it to work.

What is an example use case of using primaryfieldserializer in django rest framework?
I had a goal, to link cities and their neighborhoods together in a request response in a nested serializer. Neighborhoods have a Foriegn key to cities. for clarity here are my models and serializer originally used. class SearchCity(models.Model): city = models.CharField(max_length=200) class SearchNeighborhood(models.Model): city = models.ForeignKey(SearchCity, on_delete=models.CASCADE) neighborhood = models.CharField(max_length=200) class CityNeighborhoodReadOnlySerializer(serializers.ModelSerializer): searchneighborhood_set = serializers.PrimaryKeyRelatedField(many=True, read_only=True) class Meta: model = SearchCity fields = ('city','searchneighborhood_set') read_only_fields =('city', 'searchneighborhood_set') but that returned only the neighborhood primary keys with the cities not a full city object. This: city: "Chicago" searchneighborhood_set: 0: 5 1: 4 2: 3 city: "New York" searchneighborhood_set: 0: 8 1: 7 2: 6 instead of what it should be, this: city: Chicago searchneighborhood_set: 0: {pk: 5, neighborhood: 'River North} .... I got the above request, not by using primarykeyrelatedserializer but by using the serializer used for seralizing neighborhood objects which looks like this: class SearchNeighborhoodSerializer(serializers.ModelSerializer): class Meta: model = SearchNeighborhood fields = ('pk','neighborhood') so now replace the primarykeyrealatedserializer with my neighborhood one and the proper nested serailzer is this: class CityNeighborhoodReadOnlySerializer(serializers.ModelSerializer): searchneighborhood_set = SearchNeighborhoodSerializer(many=True, read_only=True) class Meta: model = SearchCity fields = ('city','searchneighborhood_set') read_only_fields =('city', 'searchneighborhood_set') so this begs the question, what is an actual use case for the primarykeyrelated … -
