How to render the options in a select of a Django form?
I would like to render two selects with Django (one multiple select, the other a simple one) and customize it with Materialize. I manage to code the following: In my forms.py class ZonesForm(forms.Form): zones_options = ( (1, 'Zone 1'), (2, 'Zone 2'), (3, 'Zone 3'), (4, 'Zone 4') ) zones = forms.MultipleChoiceField(widget=forms.CheckboxSelectMultiple, choices=zones_options) conn_options = ( (1, 'ABCDE'), (2, 'FGHIJ'), ) connections = forms.ChoiceField(choices=conn_options) In my zones.html {% block content %} <div class="container"> <div class="row"> <form method="post"> <div class="input-field col s6"> <select multiple name="{{ form.zones.name }}"> {% for opt in form.zones %} <option value="{{ opt.id }}">{{ opt.label }}</option> {% endfor %} </select> <label>Zones</label> </div> <div class="input-field col s6"> <select name="form.connections.name"> {% for opt in form.connections %} <option value="{{ opt.id }}">{{ opt }}</option> {% endfor %} </select> <label>Connection</label> </div> </form> </div> </div> {% endblock %} My problem is: when the page is rendered, I get 4 checkboxes for the first select (as expected), and no names for it (all options are blank). For the second select I get 4 options (one blank, one with 'ABCDE', one blank, one with 'FGHIJ'). I suspect that the problem is with the attributes. I am not getting the right values for them (I have tried … -
Django Gmail API send EMails
Im already using Gmail API for login in my Django project. Im using social-auth-app-django 2.1.0 SOCIAL_AUTH_GOOGLE_OAUTH2_KEY = 'XXXXXX.apps.googleusercontent.com' SOCIAL_AUTH_GOOGLE_OAUTH2_SECRET = 'XXXXXXX' now I want to extend this and also send emails via the Gmail API. This means that the sender of the email is the user's own email and not the one from the project page. I've been looking at the reference here. https://developers.google.com/api-client-library/python/guide/django But it doesn't seem to be up-to-date, already the modules CredentialsField and FlowField can't be imported. So my question is, is it possible to integrate this directly via social-auth-app-django as described? If so, how could this be implemented? Unfortunately I didn't find anything suitable on the internet how I could realize it in Django. Im using Django 2.1.3 on Python 2.5.4 -
How to merge the result of two queries using update
I have to show the name of the category and the quantity of items in each category. The items can change the category, so I save the history of the items in the table items_history To show all the category name I'm running this query: category_total = Category.objects.all() Example of result: <QuerySet [<Category: Drink>, <Category: Food>, <Category: Fun>, <Category: Suplies>]> To get the quantity of items in each category, I have to check in the table items_history: items_history = Category.objects.filter(items_history__current=1).annotate(qtd=Count("items_history__idea_id")) Example of result: <QuerySet [<Category: Food>]> items_history[0].name -> 'Food' items_history[0].qtd -> 5 In this case, I have only items in Food Category. So I can't do just one query in items_history, because I'm not gonna get the quantity of the items in the other categories (0, in this case). I need to get all the categories with their respective quantity, so if a category is not persisted in items_history I should get the category name and the quantity = 0. The result expected: items_history[0].name -> 'Drink' items_history[0].qtd -> 0 items_history[1].name -> 'Food' items_history[1].qtd -> 5 items_history[1].name -> 'Fun' items_history[1].qtd -> 0 items_history[1].name -> 'Suplies' items_history[1].qtd -> 0 I'm trying to use update to merge the result of category_total and items_history … -
registered router url returns 404
I'm using django and rest-framework to develop a website. I have a users app in which the models are shown below: class User(AbstractUser): pass class Comment(models.Model): comment_text = models.TextField() author = models.ForeignKey(settings.AUTH_USER_MODEL,default=DefaultUser,on_delete=models.SET_DEFAULT,related_name='author') # DefaultUser is similar to AnonymousUser in django.contrib.aut.models date = models.DateTimeField(default=now) class User_Comment(Comment): on_user = models.ForeignKey(User,on_delete=models.CASCADE,related_name='on_user',default=DefaultUser) class User_Comment(Comment): on_user = models.ForeignKey(User,on_delete=models.CASCADE,related_name='on_user',default=DefaultUser) so it's basically a comment system where a user can comment on another user. I've used a rest framework serializer for posting comments: class User_CommentSerilizer(serializers.ModelSerializer): comment = User_Comment class Meta: model = User_Comment fields = ('comment_text','on_user') # extra_kwargs = {'password': {'write-only': True}} def create(self, validated_data): comment = User_Comment( author= User.objects.filter(username=self.context['request'].user)[0], on_user= User.objects.filter(username=validated_data["on_user"])[0], validated=False, comment_text= validated_data["comment_text"] ) comment.save() return comment and then using a UserCommentViewSet in views.py: class User_CommentViewSet(viewsets.ViewSet): serializer_class = User_CommentSerilizer queryset = User_Comment.objects.all() and finally in the urls file I've registered the view: router = DefaultRouter() router.register('profile' , views.UserViewSet) router.register('comment' , views.User_CommentViewSet) router.register('login' ,views.LoginViewSet, base_name='login') urlpatterns = [ # path('', views.GetUser.as_view()), path('users/', include(router.urls)), ] the profile and login routers are working fine. however the comment router is not showing at all (and returns 404) without raising any other error. I can't figure out what the problem is Although I did find out that it has something … -

Error moving SQL query from Postgres to MariaDB
This is part of a query which works fine in PostgreSQL (in a Django app): CASE WHEN abc.name = 'foo bar' AND user.first_login <= (now() - interval '{new_user_interval} day') THEN 0 ELSE COALESCE(abc.rank, 0) END AS interesting_value, However, when I try to run it in a MariaDB database, I get this error: You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near ') THEN 0\n ELSE COALESCE(abc.rank, 0)\n END AS interesti' at line 13" It seems to follow the MySQL case operator syntax fine.

get_context_data function doesn't return the 'form'
I have the following Django code (django version 1.11) of a form: class MyDocumentUpdateView(UpdateView): """ We extend UpdateView as we need to pass self.object in context as resource """ model = MyDocument def get_context_data(self, **context): context[self.context_object_name] = self.object context['resource'] = self.object #context['form'] = self.get_form() <-- if I uncomment this it works return context class DocumentUpdateView(MyDocumentUpdateView): form_class = MyDocumentForm def form_valid(self, form): doc = form.save(commit=False) doc.owner = self.request.user updateMyDocument(doc, form) return HttpResponseRedirect( reverse( 'mydocs_detail', args=( self.object.slug, ))) When I run this code, I get an error: 'str' object has no attribute 'fields' I realized that this error related with the return of the context variable. For some reason the context dictionary does not include the 'form'. As indicated in the documentation: get_context_data(**kwargs)¶ Calls get_form() and adds the result to the context data with the name ‘form’. But in my case the context dictionary does not include the 'form'. If I use the get_form() def, then everything works: context['form'] = self.get_form() But this seems like an overkill to me and I want to dig deeper on why this doesn't work. Then I have noticed that in my case I use: def get_context_data(self, **context): instead of: def get_context_data(self, **kwargs): So I defined the … -

Python web service for controlling TCP server
What is the best way to create a web API, that would be able to control TCP server? I've tried to do it the following way: import socket from flask import Flask # tcp server TCP_IP = '0.0.0.0' TCP_PORT = 5001 BUFFER_SIZE = 20 app = Flask(__name__) light_on = False @app.before_first_request def launchServer(): global light_on s = socket.socket(socket.AF_INET, socket.SOCK_STREAM) s.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1) s.bind((TCP_IP, TCP_PORT)) s.listen(1) CONN, addr = s.accept() while light_on: data = CONN.recv(1024) # SOME LOGIC HERE CONN.shutdown(socket.SHUT_RDWR) CONN.close() @app.route('/start') def start(): print('starting') global light_on light_on = True launchServer() return "Started" @app.route('/stop') def stop(): global light_on light_on = False return "Stopped" if __name__ == "__main__": app.run(host='0.0.0.0', debug=True, port=5000, use_reloader=False) Also, I've packed this app in docker file, and unfortunately I'm not even able to use /start handler. What is the proper/best way to create such web service (Flask is no strict requirement, I can use any python framework)?

Python/Django random DB query results due to "Default argument value is mutable" in method
I encountered a bug in my Django app yesterday and even though I fixed it since, I still do not understand its cause, neither how I resolved it. Well, actually I found the root cause while writing this question, thanks to SO "Questions with similar titles" feature. See "Least Astonishment" and the Mutable Default Argument Buuut, I still don't understand how could that affect my app in the way it affected it. So, let's dig in. I have a web page, which display a list of items. I query those items through the Model.get method, from the views.py file. Nothing out of the ordinary, basically fetching the DB from the model, calling the model from the view and providing a variable with the fetched values to the template. When using the faulty source code, I would refresh the page and the items would randomly either appear, or disappear. I figured the DB query would either return the items, or return an empty list. Here is the faulty source code (model.py): @classmethod def get(cls, school=None, additional_filters={}): if school: additional_filters['school'] = school return MyModel.objects.filter( **additional_filters ) And here is how I fixed it: @classmethod def get(cls, school=None, additional_filters=None): if not additional_filters: additional_filters … -

Could not display the updated model using modelForm in django

Django admin restrict access to list view
Here is a model: class Person(models.Model): name= models.CharField(max_length=100, blank=True) identity_number= models.IntegerField(unique=True) name field should be public, identity_number, however, should be confidential. I would like to show name in admin list view and both fields in change form view. I would like to create one group of users, who can access only list view and another group of users, who can access both views. This means that the first group of users should not see links to change form and if they try to access the change form page directly, 403 (or something like that) should be returned. How to achieve this? -
How to send null for Integerfield from form in DRF

Django MIGRATION_MODULES in cookiecutter-django
I have been playing a bit with cookiecutter-django and I'm confused about something: They set MIGARATION_MODULES in settings as follows: MIGRATION_MODULES = { 'sites': 'my_awesome_project.contrib.sites.migrations' } and that module contains 3 migrations: 0001_initial.py 0002_alter_domain_unique.py 0003_set_site_domain_and_name.py Those first two are copies of the original Django Sites package, and the third one updates the db with the domain name of the project (as described here). This all makes sense. But what happens if The-Powers-That-Be make another migration in Django Sites? Presumably it would be dependant on migration 0002 as well, leading to a conflict. Would it even get read, given that the MIGRATION_MODULE for 'sites' no longer checks that original module? Just curious. -
