django 1.8 linking to existing MySQL Database
I'm currently trying to link my django app so an existing MySQL db (To qualify, the database is linked in settings and django can see the db and inspect) Im working on a dev version of the db before lining to the operational db. I have run ./manage.py inspectdb > models.pyand fixed the models created by django to match the schema. From my undderstanding of the docs (I normaly create new postgres dbs. Not link to existing) I still have to run migrate before running runserver. From what I can see in the SQL django recreates all the tables (along with its own) but prefixed with the app name. I am assuming that the data from django will be used in the tables created by django rather than the exisiting tables. I have read that you can fake migration with --fake-initial but I am unsure if this will resolve my issue or cause more problems once in production. Any help with understaning this would be appreciated. -
TemplateDoesNotExist when using Django package
I followed this Django tutorial: https://docs.djangoproject.com/en/1.10/intro/reusable-apps/. I have a project called oldcity and an app called oldantwerp. The app is located in a parent directory called django-oldantwerp and the app directory itself has a subdirectory templates. The index.html file that my project is looking for is situated like so: django-oldantwerp>oldantwerp>templates>oldantwerp>index.html I tried to use this app with my project by including it in settings.py: INSTALLED_APPS = [ 'django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', 'django.contrib.staticfiles', 'oldantwerp' ] and in urls.py (in the projec), like so: urlpatterns = [ url(r'^oldantwerp/', include('oldantwerp.urls')), url(r'^admin/', admin.site.urls), ] When I go to the admin page, everything works, but when I try to open the index page I get this error: TemplateDoesNotExist at /oldantwerp/ It says it tried to locate the index.html file like so: Template loader postmortem Django tried loading these templates, in this order: Using engine django: * django.template.loaders.filesystem.Loader: /Users/Vincent/Apps/oldcity/templates/oldantwerp/index.html (Source does not exist) * django.template.loaders.app_directories.Loader: /Users/Vincent/Apps/oldcity/venv/lib/python3.4/site-packages/django/contrib/admin/templates/oldantwerp/index.html (Source does not exist) * django.template.loaders.app_directories.Loader: /Users/Vincent/Apps/oldcity/venv/lib/python3.4/site-packages/django/contrib/auth/templates/oldantwerp/index.html (Source does not exist) And it also tried searching for another file: place_list.html, which is strange because I don't think I have such a file. What could be wrong? -
Include a Foreign Key in the Django GeoJSON serializer
When I serialize an object with geojson, I would need to add a field containing a reverse Foreign Key. I use Django 1.9 and have the following models: class NaturalEarthProvince(models.Model): adm1_code = models.CharField(max_length=10, primary_key=True) name = models.CharField(max_length=100) geom = models.MultiPolygonField(srid=4326) objects = models.GeoManager() class NaturalEarthMerged(models.Model): basicname = models.CharField(max_length=200, blank=True) fkprovince = models.OneToOneField(NaturalEarthProvince, blank=True, null=True) fktouristicarea = models.ForeignKey(TouristicArea, blank=True, null=True, related_name='relatednatmerged', on_delete=models.SET_NULL) class TouristicArea(models.Model): areaname = models.CharField(max_length=200, blank=True) fkcountry = models.ForeignKey(NaturalEarthCountry, blank=True, null=True) What I would like to do is: location = NaturalEarthProvince.objects.filter(adm0_a3=code) locationserialized = serialize('geojson', location, geometry_field='geom', fields=('name', 'adm1_cod_1', 'touristicarea') with touristicarea being location.naturalearthmerged.fktouristicarea Any clue? -

Delete Member of Many To Many Relationship Django Rest Framework
Given the following system # Models class Team(models.Model): name = models.CharField(max_length=128) class Player(models.Model): name = models.CharField(max_length=128) teams = models.ManyToManyField(Team) # Serializers class PlayerSerializer(serializers.ModelSerializer): teams = serializers.PrimaryKeyRelatedField(many=True, queryset=League.objects.all(), required=False) class Meta: model = Team fields = ('id', 'name', 'teams') # Views class TeamViewSet(viewsets.ModelViewSet): queryset = Team.objects.all() serializer_class = TeamSerializer Basically a player can be in many teams So the question is, how do I implement endpoints to manage the player-team relationship. Say we have two teams with ids 1, and 2 I create a player with POST /players/ {'name': 'player1'} this player will have Id 1 I want to add player to teams 1 and 2, and then remove player from team 2 With this setup I can do PATCH /players/1/ {'teams': [1, 2]} How do I now remove player1 from team 2? Also, is using a patch request to add player1 to teams 1 and 2 the correct way to do this? -

Synchronizing different Web-Services (Django) and their DBs through RESTful interfaces with push/pull mechanism, like with GIT
I am looking for a way to maintain the DBs of multiple web-services in synchronization. I have a system made of: Multiple Local web-services, with their own private DBs Own Central web-service, with its own DB A subset of the Local DBs can be pushed to the Central DB in order to update it. On a regular basis the Local DBs shall be able to pull the latest update from the Central DB. The idea is to have something very similar to what git VCS does: Push/Pull mechanism Conflicts management from the the 'sender/fetcher' point of view. This is depicted in the following diagram: ________ _.-----._ |==|=====| .- -.| | | |-_ _-|| | | | ~-----~ || | |--------Push/Pull----------. | Local DB || | | | `._ _.'| |====°| | "-----" |__|_____| | .--. |_ -( )- _ ________ .--,| ),--. _.-----._ |==|=====| _.-( | INTERNET )-._ .- -.| | | ( ____v___ ) |-_ _-|| | | '-.|==|=====| )_.-' | ~-----~ || | |------Push/Pull------>| | | _.-----._ ' | Local DB || | | | | |.- -. `._ _.'| |====°| | | ||-_ _-| "-----" |__|_____| | | || ~-----~ | | |====°|| CENTRAL DB| ________ |__|_____|`._ … -

Django - How to change value of forms.ModelChoiceField
I want to output the value from my Models Name column using forms.ModelChoiceField. I have read a lot of documentation on the subject but its proving difficult to achieve the desired results!

Filtered Nested Relationships Django Rest Framework
I have two models which look like the following: class Subject(models.Model): subject_code = models.CharField(max_length=12, unique=True) name = models.CharField(max_length=100) dept_code = models.CharField(max_length=6) and... class Subject_assessment(models.Model): subject_code = models.ForeignKey(Subject, related_name='sub_assessments') year = models.CharField(max_length=4) name = models.CharField(max_length=50) I have created my serializes in such a way that when I retrieve a subject, I also retrieve the assessments associated with that subject. I am using the following serializers to accomplish this: class AssessmentsSerializer(serializers.ModelSerializer): class Meta: model = Subject_assessment fields = ( "subject_code", "year", "name" ) class SubjectSerializer(serializers.ModelSerializer): sub_assessments = AssessmentsSerializer(many=True) class Meta: model = Subject fields = ( "subject_code", "name", "dept_code", "sub_assessments" ) This code works perfectly as anticipated as it gives me a result like this: { "subject_code":"ECR2243", "name":"Statistics", "dept_code":"Stats", "sub_assessments":[ { "subject_code":"ECR2243", "year":"2017", "name":"Test 1" }, { "subject_code":"ECR2243", "year":"2016", "name":"Test 1" } ] } My problem is that I wish to retrieve assessments only for a specific year. For example, If I pass 2017 as the year of interest, I do not wish to retrieve assessments for 2016 like I am currently getting. Can anyone please assist on how I can structure my code in order to accomplish this. Thank you in advance. -
Writing several fields in one row in a csv with python
I'm working on improving some open-source code for a psychological test. For an output of data I'm using python's CSV module, which works fine in itself. The data output is dependent on the django model (trials) and the respective database entry and I want to add the data from another model (participant) to the csv. So far I only managed to add the required entries in a new row but this basically renders the csv unusable for further use in statistics programs. In short what I get: headers of database entry 1 headers of database entry 2 values of database entry 1 values of database entry 2 But what I want is the output to look like this: headers of database entry 1 followed by 2 values of database entry 1 followed by 2 This is what the important part of the export looks like. for participant in queryset: rows = [headers_participant] + [headers] participants = Participant.objects.filter(id=participant.id) trials = Trial.objects.filter(participant=participant.id) for participant_value_list in participants.values_list(*fields_participant): rows.append([unicode(v) for v in participant_value_list]) for trial_value_list in trials.values_list(*fields): rows.append([unicode(v) for v in trial_value_list]) I do understand that the output as it is now is caused by me calling rows.append twice but right now I don't … -

Saving formset saves a bunch of blank forms
So I have a view where I can add as many forms as the user wants with an add row function and then click save. The page displays existing forms and allows you to add new ones. When I save the first one it all works fine. Then as I continue to save, it saves the new record PLUS a number of blank records, the number being equal to the number of forms we see on the page (existing + the number you are trying to add). I have allowed fields to be blank because I needed to populate some fields in the view. Without this I was getting validation errors when i ran a False commit to then populate fields and save.

Authentication Backends file
I wish to customize my authentication backends, i'm a beginner in django and i want to practice, but i am alittle confused. I red the documentation but for their example and for each example i found, no one says where you should write the class. Do you have to add your class in the default django backends.py? or do you have to create your own backends.py and add it after to Settings.py? Another thing, i want to know if the authorizations and permissions have to be written in the same customized backends.py.
