Django admin - Create a edit button for each row
I have to create a django admin button that makes each row of my table editable(after i click the button). And then save the edited row without redirecting to any page. To be 100% clear: when clicking 'edit' all fields in that row will be editable. 1 edit button per row. django admin image: https://gyazo.com/def02a6ed68ddc2e777c0daaf26a0c5d my admin.py from django.contrib import admin from .models import Remedio from django.contrib.admin import AdminSite class MyAdminSite(AdminSite): site_header = 'Farmacia' class RemedioAdmin(admin.ModelAdmin): fieldsets = [ (None, {'fields': ['descricao']}), (None, {'fields': ['data_de_fabricacao']}), (None, {'fields': ['data_de_validade']}), (None, {'fields': ['manipulado']}), (None, {'fields': ['maioridade']}), (None, {'fields': ['preco']}), (None, {'fields': ['faca_editar']}), ] list_display = ('descricao', 'data_de_fabricacao', 'data_de_validade', 'preco', 'maioridade', 'manipulado', 'faca_editar') list_filter = ['preco'] search_fields = ['descricao', 'preco'] list_editable = ['preco'] list_display_links = ['data_de_fabricacao'] # readonly_fields = ['preco'] def make_price_zero(self, request, queryset): queryset.update(preco=0.00) make_price_zero.short_description = "Marque os remedios que queira zerar o preco" actions = ['make_price_zero'] admin.site.register(Remedio, RemedioAdmin) admin_site = MyAdminSite(name='farmacia_vitu') my models.py from __future__ import unicode_literals from django.db import models class Remedio(models.Model): descricao = models.CharField(max_length=200) data_de_fabricacao = models.DateTimeField() data_de_validade = models.DateTimeField() imagem = models.ImageField() maioridade = models.BooleanField() manipulado = models.BooleanField() preco = models.DecimalField(decimal_places=2, max_digits=8) faca_editar = models.URLField() def __str__(self): return self.descricao -
How to set up Django MySQL Database on pythonanywhere?
It's the first time I'm deploying a site using MySQL instead of SQLite3, so I'm quite new at this, after reading some documentation I found out that I have to change some files like this : settings.py DATABASES = { 'default': { 'ENGINE': 'django.db.backends.mysql', 'NAME': 'my_site_db', 'USER': 'username', 'PASSWORD': 'password', 'HOST': '?', #currently using pythonanywhere (not on localhost) 'PORT': '?', } } manage.py try: import pymysql pymysql.install_as_MySQLdb() except: pass (PyMySQL==0.7.10, Django 1.9, Python 3.5) When I run the Bash Console using python manage.py migrate I get this error message : django.db.utils.OperationalError: (2003, "Can't connect to MySQL server on 'localhost' ([Errno 111] Connection refused)") I thought it has something to do with the HOST and the PORT from the Database configurations, I don't know what I should add in these, does it have to do with MySQL, PythonAnywhere or even my own domain ? How can I resolve this problem and set up MySQL correctly with Django 3.5 ? -
Django make_aware usage
Django docs says: The pytz.NonExistentTimeError exception is raised if you try to make value aware during a DST transition such that the time never occurred (when entering into DST). Setting is_dst to True or False will avoid the exception by moving the hour backwards or forwards by 1 respectively. For example, is_dst=True would change a non-existent time of 2:30 to 1:30 and is_dst=False would change the time to 3:30. So I expect the time to be shifted one forward or backward depending on the value of is_dst. But from my tests, the timezone is being shifted, not the time. Am I misunderstanding the Django docs or this is a bug ? I tested the following : tz = pytz.timezone('America/Sao_Paulo') dt = datetime.datetime(2017, 10, 15 ,0 ,0) print(make_aware(dt, tz)) --> NonExistentTimeError print(make_aware(dt, tz, True)) --> 2017-10-15 00:00:00-02:00 print(make_aware(dt, tz, False)) --> 2017-10-15 00:00:00-03:00 -

'tuple' object has no attribute 'get' when requesting class based view Django
Hi this should be an easy one i'm sure. Just losing my patience with class based views. Not really sure how they simplify things. Function based views seem to a lot more readable and make more sense. Anyway am trying to convert one of my functional views to a class one and getting this error when I request the view 'tuple' object has no attribute 'get' Here is the urls.py from django.conf.urls import url from . import views urlpatterns = [ url(r'^upload_photo/$', views.upload_photo, name='upload_photo'), url(r'^upload_photo_class/$', views.UploadPhotoView.as_view()), ] Here is the class based view class UploadPhotoView(View): form = PhotoModelForm formset = formset_factory(PhotoExtendedModelForm, max_num=1, validate_min=True) template_name = 'upload_photo.html' @method_decorator(login_required) def dispatch(self, *args, **kwargs): return super().dispatch(*args, **kwargs) def get(self, request): form = self.form formset = self.formset return (request, self.template_name, {'form': form, 'formset': formset}) def post(self, request, *args, **kwargs): form = self.form(request.POST, request.FILES) formset = self.formset(request.POST) if all([form.is_valid(), formset.is_valid()]): photo = form.save() photo_instance = photo user_id = request.user for inline_form in formset: data = inline_form.save(commit=False) data.Photo = photo_instance data.user = user_id data.save() return render(request, 'upload_photo_done.html') else: return (request, self.template_name, {'form': form, 'formset': formset}) Here is the original function based view @login_required def upload_photo(request): form = PhotoModelForm formset = formset_factory(PhotoExtendedModelForm, max_num=1, validate_min=True) if request.method == … -
Using graphene-django, is it possible to add additional fields to specific edges?
Let's say we have three primary tables; Ingredient, Recipe, and GroceryStore whereby recipes can have many ingredients and ingredients can belong to many recipes (many-to-many relationship). Likewise, grocery stores can sell many ingredients and ingredients can be found at many grocery stores. In the many-to-many relationship between a Recipe and an Ingredient, we would like to store some additional information such as the quantity of ingredients required for a recipe, however, the GroceryStore to Ingredient relationship needs no such information and, in fact, might store something entirely different such as the price of an ingredient. We could model this as such: class Ingredient(Model): name = CharField(max_length=50) class Recipe(Model): name = CharField(max_length=50) ingredients = ManyToManyField('Ingredient', related_name='recipes', through='RecipeIngredient') class RecipeIngredient(Model): recipe = ForeignKey('Recipe') ingredient = ForeignKey('Ingredient') quantity = PositiveIntegerField() class GroceryStore(Model): name = CharField(max_length=50) ingredients = ManyToManyField('Ingredient', related_name='grocery_stores', through='GroceryStoreIngredient') class GroceryStoreIngredient(Model): grocery_store = ForeignKey('GroceryStore') ingredient = ForeignKey('Ingredient') price = DecimalField(decimal_places=3, max_digits=5) Easy enough. Now we can define some simple nodes for these models: class IngredientNode(DjangoObjectType): grocery_stores = DjangoConnectionField(lambda: GroceryStoreNode) recipes = DjangoConnectionField(lambda: RecipeNode) class Meta: interfaces = [relay.Node] model = Ingredient only_fields = ['name'] class RecipeNode(DjangoObjectType): ingredients = DjangoConnectionField(lambda: IngredientNode) class Meta: interfaces = [relay.Node] model = Recipe only_fields = ['name'] class … -
Serializing a list of objects with django-rest-framework
In DRF, I can serialize a native Python object like this: class Comment(object): def __init__(self, email, content, created=None): self.email = email self.content = content self.created = created or datetime.now() class CommentSerializer(serializers.Serializer): email = serializers.EmailField() content = serializers.CharField(max_length=200) created = serializers.DateTimeField() class CommentSerializer(serializers.Serializer): f1 = serializers.CharField() f2 = ... comment = Comment(email='leila@example.com', content='foo bar') serializer = CommentSerializer(comment) serializer.data # --> {'email': 'leila@example.com', 'content': 'foo bar', 'created': '2016-01-27T15:17:10.375877'} Is it possible to do the same for a list of objects using ListSerializer? -
Django Restful: Nested Serializers
I'm adding a 'tests' field to my 'Sample' model, where 'tests' will be a list of 'TestRequest' objects. Currently, I'm getting this error: Got AttributeError when attempting to get a value for field `tests` on serializer `SampleSerializer`. The serializer field might be named incorrectly and not match any attribute or key on the `Sample` instance. Original exception text was: 'Sample' object has no attribute 'tests'. 'tests' is not a field on my model. I'm just trying to add it to the serialized data. Currently, I can get a nested serializer to work for 'klass' but that is because it's defined in the model.

Django blog posts not being returned

Passing a variable on the template to a view
I am trying to pass a few variable to my view in django. This is to flick through months in a calendar. The information needed is whether the user wanted the next or previous month, and the current month.

Advice on troubleshooting Wagtail/SQL Azure compatibility required
My organisation is developing a new publishing platform based on Wagtail as a CMS backend. We have extensive in-house expertise in MS SQL databases, but next to none with Postgres or MySQL so would prefer to utilise MS SQL (specifically SQL Azure) - which Wagtail's docs seem to suggest is possible. I have an instance of Wagtail running and have installed a Django backend (https://pypi.python.org/pypi/django-pyodbc-azure) that claims to support SQL Azure. I have configured my database connection settings in settings.py. I can successfully run migrations and create a superuser, so I am reasonably confident that the database connectivity is good. I can then browse to the Wagtail login page at http://localhost:8000/admin but immediately upon logging in with the credentials provided to the createsuperuser script, I get the following error: ('42000', "[42000] [Microsoft][ODBC SQL Server Driver][SQL Server]Incorrect syntax near 'LIMIT'. (102) (SQLExecDirectW)") It would seem that Wagtail itself is using this LIMIT keyword which is unsupported in MS SQL - what's my best approach for troubleshooting and attempting to resolve this behaviour? Or am I on a hiding to nothing? -

Adding to a django serializer
I was using the django-serializer: object_list = ZoneEntity.objects.filter(cesiumentity__sensor__in=sensor) jdata =serialize('geojson', object_list, geometry_field = 'mpoly', fields = ('zone_number')) And it works well, but I have realized I want to pass back to my website some of what is in the object_list and some other data I create/correlate on the fly. basically add some more fields to that object_list (some that include another list) Is there a way to do this ? Without the serializer I guess just maybe passing a geojson object back somehow? -

How to customize a specific TextField inside the Django admin not all?
I have two TextField in my model. But i want to change the rows and cols attribute of only of the TextField. I know from this page that the look of TextField can be changed using the following code in the admin.py. class RulesAdmin(admin.ModelAdmin): formfield_overrides = { models.TextField: {'widget': Textarea( attrs={'rows': 1, 'cols': 40})}, } ... admin.site.register(Rules, RulesAdmin) As I said, using the above code changed the look of both the TextField, I want only to change one of those here is how my model looks like: class Lesson(models.Model): title = models.CharField(max_length=200) content = models.TextField() pub_date = models.DateTimeField(auto_now_add=True) update_date = models.DateTimeField(auto_now=True) meta = models.TextField(blank=True) def __str__(self): return self.title I want only to change the look of meta field. How should I go about this ?
