Seleium Can not lauch Chrome Browser on Apache via mod_wsgi
I am developing a Django Project. I use a view named test_seleium_view() to lauch a Chrome Browser by Seleium. For demonstration purpose, my code is as simple as below: urls.py # coding=utf-8 from __future__ import unicode_literals, absolute_import from django.conf.urls import url from .views import * urlpatterns = [url(r'^test_seleium$',test_seleium_view,name='test_seleium'),] test_seleium.py # coding=utf-8 from __future__ import unicode_literals, absolute_import import time from django.shortcuts import render_to_response from selenium import webdriver def test_seleium_view(request): chrome_options = webdriver.ChromeOptions() chrome_options.add_argument("--start-maximized") chrome_options.add_argument('--disable-extensions') CHROME_DRIVER_PATH = r"C:\Program Files (x86)\chromedriver\chromedriver_win32_v2.43.exe" driver = webdriver.Chrome(executable_path=CHROME_DRIVER_PATH, chrome_options=chrome_options) driver.get('http://www.google.com') time.sleep(5) driver.quit() return render_to_response('result.html',{'text': "success"}) When I visit http://127.0.0.1:8000/app_name/test_seleium on Django development server, everything is working fine, Seleium lauch a Chrome browser then open http://www.google.com wait for 5 seconds then close Chrome browser. Then I take this Django project to my virtual machine(VMware Workstation, win 7 64bit installed) which installed Apache and mod_wsgi, when I visit http://my_vmware_virtual_host_ip:8000/app_name/test_seleium, it doesn't lauch Chrome browser, but after a while, the page show the text "success",just like test_seleium_view() had ran successfully, and there is a chrome.exe process on windows 7 background. my environment： VMware Workstation 15.0.0 build-10134415 Windows 7 64bit on VMware Virtual Machine Apache 2.4.37 Win64 mod_wsgi 4.6.5+ap24vc14-cp36-cp36m-win_amd64 python 3.6.4 64bit Django 2.0.7 selenium 3.14.1 chromdriver win32_v2.43，win32_v2.42 I search this … -
Graphene Django: Change field names
If I have a Django model with fields names in french like this (nom is the french translation of name): class Categorie(models.Model): nom = models.CharField(max_length=100) def __str__(self): return self.nom Is it possible to configure a GraphQL Query with Graphene Django in order to query the graph with an english translation of the field (using name instead of nom): query { allCategories { id name } } Thanks, -
Django changes made to M2M field by signals not saved
I have the following models : class Case(models.Model): title = models.CharField(verbose_name="Titre", max_length=1000) statement = models.CharField(verbose_name="Énoncé du problême", max_length=1000) class GivenCase(models.Model): given_case = models.ForeignKey(Case, on_delete=models.CASCADE) title = models.CharField(verbose_name="Titre", max_length=1000, null=True) user = models.ForeignKey(User, on_delete=models.CASCADE, null=True) class Candidate(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE, null=True) cases = models.ManyToManyField(GivenCase, verbose_name="Cas", related_name="cases", blank=True) assigned_cases = models.ManyToManyField(Case, verbose_name="Cas assignés", related_name="assigned_cases") To put it simply, I have Candidates that can have multiple Cases, whenever a Case is assigned to a Candidate the signal is handled and a GivenCase is created and assigned to the Candidate. Here's my signal handler : @receiver(models.signals.post_save, sender=Candidate) def generate_exercise_for_new_user(sender, instance, **kwargs): cases = Case.objects.all() assigned_cases = GivenCase.objects.filter(user=instance.user).values_list("title", flat=True) for case in cases: if case.title not in assigned_cases: new_case = GivenCase(title=case.title, given_case=case, user=instance.user) new_case.save() instance.cases.add(new_case) if new_case in instance.cases.all(): print("ITS HERE") my problem is when I make changes to a Candidate in the admin view the signal code is firing (checked with prints) and the new_case is saved in my M2M field (the last if at the end of the signal returns true), despite all that when I go back to my Candidate after saving the changes no GivenCase is saved inside it despite being created (They are visible in the available Case, but … -
Celery not queuing to a remote broker, adding tasks to a localhost instead
My question is same like this Celery not queuing tasks to broker on remote server, adds tasks to localhost instead, but the answer is not working to me.

Django Rest Framework deserialize queryset into other model
I have a generic 'Order' model. There are other models which represent other forms of 'Order's. I need to deserialize these other instance to our generic 'Order' model. So I retrieve a queryset and turn it into a list but am unable to correctly deserialize it into Order. Order has 4 fields, reference, delivery_date, note and customer_note. The other model has equivalent fields named external_reference, expected_delivery_date, note and customer_note. class OrderSerializer(serializers.ModelSerializer): reference = serializers.CharField(source='external_reference', required=True) delivery_date = serializers.DateField(source='requested_delivery_date') note = serializers.CharField() customer_note = serializers.CharField() class Meta: model = Order fields = ('reference', 'delivery_date', 'note', 'customer_note') Since you can't provide a QuerySet as data input for a Serializer I turned it into a list: orders = AppOrder.objects.all() data = list(orders.values()) serialized = OrderSerializer(data=data, many=True) However, this does not work. Source does not grab the correct field: delivery_date': ['This field is required.'] It may be that I am doing this entirely wrong and that there are better ways to deserialize one model to another, if so please do tell as well. -
Django forms concurrency/validation problem
I have a question regarding django form validation and concurrency. Say I have a invoice form where the form clean checks if on of the invoice positions about to be created already exists in an other invoice (check is executed via querying the database!). If so it raises an validation error. Now I have the case that 2 users create a new invoice with the identical position and click on save at the same moment. The form validation passes in both cases because the first invoice was not saved to database while the second one passes the form validation. Now I have 2 invoices with the same position which should not be possible. Is there a decent way to solve this problem? Thanks for your help! Jonas -

django list model entry with multiple references
I have the following models which represent songs and the plays of each song: from django.db import models class Play(models.Model): play_day = models.PositiveIntegerField() source = models.CharField( 'source', choices=(('radio', 'Radio'),('streaming', 'Streaming'), ) ) song = models.ForeignKey(Song, verbose_name='song') class Song(models.Model): name = models.CharField('Name') Image I have the following entries: Songs: |ID | name | |---|---------------------| | 1 | Stairway to Heaven | | 2 | Riders on the Storm | Plays: |ID | play_day | source | song_id | |---|----------|-----------|---------| | 1 | 2081030 | radio | 1 | | 1 | 2081030 | streaming | 1 | | 2 | 2081030 | streaming | 2 | I would like to list all the tracks as follows: | Name | Day | Sources | |---------------------|------------|------------------| | Stairway to Heaven | 2018-10-30 | Radio, Streaming | | Riders on the Storm | 2018-10-30 | Streaming | I am using Django==1.9.2, django_tables2==1.1.6 and django-filter==0.13.0 with PostgreSQL.

Override 'create' function in Django serializer
I wonder how to handle POST request to properly save the incoming data, having such models: class Recipe(models.Model): author = models.ForeignKey('auth.user', related_name='recipes', on_delete=models.CASCADE) image = models.TextField(default='None') name = models.CharField(max_length=100) description = models.TextField(default='No description') votes = models.IntegerField(default=0) def __str__(self): return self.name class Ingredient(models.Model): image = models.TextField(default='None') name = models.CharField(max_length=100) description = models.TextField(default='No description') price = models.DecimalField(max_digits=8, decimal_places=3) unit_price = models.DecimalField(max_digits=8, decimal_places=3) unit_quantity = models.CharField(max_length=20) def __str__(self): return self.name I wanted to avoid duplicating Ingredient objects, so to provide quantity of specific Ingredient in Recipe I've created a RecipesIngredient model that binds Ingredient with Recipe, but also contains a quantity of this Ingredient: class RecipesIngredient(models.Model): recipe = models.ForeignKey(Recipe, related_name='ingredients', on_delete=models.CASCADE) ingredient = models.ForeignKey(Ingredient, on_delete=models.CASCADE) quantity = models.CharField(max_length=100) def __str__(self): return self.quantity I've also prepared some serializers for these models: class IngredientSerializer(HyperlinkedModelSerializer): class Meta: model = Ingredient fields = ( 'url', 'image', 'name', 'description', 'price', 'unit_price', 'unit_quantity' ) class RecipesIngredientSerializer(HyperlinkedModelSerializer): ingredient_name = ReadOnlyField(source='ingredient.name') ingredient_price = ReadOnlyField(source='ingredient.price') ingredient_unit_price = ReadOnlyField(source='ingredient.unit_price') ingredient_unit_quantity = ReadOnlyField(source='ingredient.unit_quantity') class Meta: model = RecipesIngredient fields = ( 'url', 'ingredient_name', 'quantity', 'ingredient_price', 'ingredient_unit_price', 'ingredient_unit_quantity' ) class RecipeListSerializer(HyperlinkedModelSerializer): author = ReadOnlyField(source='author.username') author_url = ReadOnlyField(source='author.url') class Meta: model = Recipe fields = ( 'url', 'author', 'author_url', 'image', 'name', 'description', 'votes' ) class RecipeDetailSerializer(HyperlinkedModelSerializer): … -
MySQL in 5 different locations Mac OS. Unable to access database
Okay, I'm still a beginner here..clearly. I am running a django python project that was set up with MySQL and the database was accessed through SequelPro. All working fine. Set up a new project, new virtualenv, and went to configure MySQL but was having lots of problems. Checked the MySQL server under settings to see if was running and it was totally unresponsive with no ability to connect / start server etc. I re downloaded the MySQL community server. It gave me new root password etc. I've discovered I now have 5 instances of mysql on my computer. (lol) The 5 paths are usr/local/mysql usr/local/mysql.5.7.23-macos10.13-x86_64 usr/local/mysql.bak usr/local/var/mysql /Applications/XAMPP/xamppfiles/var/mysql/ The databases that I have been working on are located in only the 3rd and 4th locations usr/local/mysql.bak/data usr/local/var/mysql/data The connection to said database no longer works through SequelPro, it throws MySQL said: Access denied for user 'root'@'localhost' (using password: YES) If someone can point me in the right direction to remedy this and not lose my databases I'd really appreciate it. -

Allow a user to authorize another user with read only permision to Google Analytics by code
I need to allow users to give read-only permission to a second user, identified by the email address, to a Google Analytics property. What I do now is similar to the sample in: https://developers.google.com/analytics/devguides/config/mgmt/v3/user-management But, this way I need the user to give the app a token with user management permissions. Is there a way I can do this without user management permissions? Maybe given the user with a link, so he can give another user access using the same Google Analytics permission interfaces? But facilitating the process. Thanks, Rodolfo -

Django Manager for Group model does not work - returns empty queryset
I'm junior dev. I want to create managers for Django Groups. One new one and one that will overwrite default manager EDIT: Django 1.8, python 2.7.15 My managers: class DefaultGroupManager(models.Manager): def get_queryset(self): test_ids = Test.objects.values_list('rel_group_id', flat=True) return super(DefaultGroupManager, self).get_queryset().exclude(id__in=test_ids) class AllGroupsManager(models.Manager): def get_queryset(self): return super(AllGroupsManager, self).get_queryset().exclude(rel_group__start_date__lte=datetime.now()-timedelta(days=30)) With these managers I created something like this: dgm = DefaultGroupManager() agm = AllGroupsManager() agm.contribute_to_class(Group, 'get_all') dgm.contribute_to_class(Group, 'objects') And it was working. I could use Group.get_all.all() and new Group.objects.all(). In return I had proper lists of objects. But my senior dev said that I have to do it by creating the new Group model that inherits from Group. So I did: My Group model: class GroupModel(Group): get_all = DefaultGroupManager() objects = AllGroupsManager() But it does not work! When I use GroupModel.get_all.all() or overwrited GroupModel.objects.all() it returns empty list [] Everything seems to be good :( I will appreciate any help! -

It is not recognized by image viewer. b'\x89PNG\r\n\x1a\n\x00\x00\x00\rIHDR\x00\x00\x03 \x00\x00\x02X\x08\x06\x00\x00\x00\x9av\x82p\x00\x00 \x00IDATx^\x8c\xbdks$Yr\x1dx#2\x12@U\xf5kD\x0e\xf7W\xe9\xc3\x9a\x96\x1c\xa3v?\xe9\xc1\x99\xa6(\xfd\xe5\xb5\xb55\xe9\x039\xd3\xd3\xdd\xd5\xf5\x002#Rv^\xee7QM\x8d0\x04Q\rdFF\xdc\x87\xbb\x9f\xe3\xc7\xfd.\xff\xf6\x1f\xff\xe3\xed\xb4\xae\xe3\xb4\x8c\xb1\x0e}\xed\xeb\x18\xb7\xdbm\x1c\xf8\xf7m\x8c\xeb\xbe\x8f\x1d\xff\xb5,\xe34Nc[\xf5\xfdv_\xc68nc\xd9oc=n|\xef\xe9\x86w\x8d\xb1\x8c\xdb8\xad\xcbX\x96e\xec\xeb\xc1\x9f\xd7\xe54\xf6u\xe1\xb5\xc7m\xd5\xcf\xb1\xe8\xd5\xb7\xdb\xb8\x8e\xdb8n7\xfe\x1b\xaf_\x17\xfcM_+\xeeo\xc1-,\xe3\xb6_\xc7\xe5r\x19\x97\xe3\x18\xc7\xba\x8e\x85\xf7\xff\xc8\xeb,\xb8\x1f^\xf76N\xe3\xca\xd7\x9fV\xfc\xe5\xe0u\xf1\xbd\xae\xeb\xb8\xe17\xb8\x8d\xdbm\xec\xb7u\x9cN\'\xdeo}\xc6\xe1{\xd9\xf7\xb1\xf2=\xf8\xdb\xce{\xb9q4p\xbd1\xf6\xd3i,\xcb:\x8e\xdb2\x8ec\x8c}\xc7\xb3\xe2w\xf8\xd6\xfd\xf33\xc61N\xebi\x9c\x97\x85\xdfx6\\\xefv\xc3u\xae\xe3\xb8]\xc7\xbe\xdf\xc6\xed8\xe99n+\xbf\xf1\xb5\xadc\xacx\x881\xc6q\xdc8\x1f/\xb8\x17\x8c\xc5\xb2\xf0\xf95V\xeb\xd8\xf7}\x1c\xb8\x11\\\x85c\xaf\x9f\x07_\xab\xe7\xe7\'\xac\xcb8c\x8c<&c\xd7Xq\x11x\xfe\xf7\xab\xc6\xec\xc0\\\r=\xcf\xb1\xeay\xf1yy>|\xf2\xb1\xef\xe3\x86\xb1\xf7\xf3\xe6\xf3\x97\xa1g\xc5k\x97C?o\x03\xd7[\xf9\x1e\xfc\x8fs}\xba\x8d\xd3i\x8c\xd3i\x1d\xa7\xe3Z\xd7\xd1\xf3^\xc7\x0bW\xc7m\x1c\xcb\x18\xb7\xd3\xca9\\\x8eM\xf3{[\xc66N\x9c\xa3q\xdb4N|u\x7fi\\\xf0YC\xf3\xbf\x9cj=\xf0\xf3\xd7u\x1c\'\xad\xc3\x1d\xeb\xeb\xfa2\xf6\xcb\x85\x9f}\\\xaf\xe3\xc3\xfb\x97\xf1\xfe\xc7\xcf\xe3\xf9\xf9e|\xfb\xf5\xd7\xe3\xed\xdb\xb7\xe3q\x1b\xe3\xbc\xeec\xdb\xd6\xf1n[\xc6\xd3\xe3\xc3\x18\x0f\xd8?\xfb\xd8o\xb7q\xb9\x9d\xb8\x9e\xd7c\x1d\xa7\x9b\xc6\xec\xe1\xd0\xcf\x15s\xec\xdb\xbbn\x0b\xc7\xee\xe5\xb6\x8f\x0bw\xdd\x18\xc7\x92\xdd\x88\xf9[=~W\xcd\xeb\xed\x18\xcb\rk\x87\x0b\x90c6VN4\xd7\xef6\xf61n\xc78\xdd\x06fM\xeb`l\\\x17\x17\xacQN2\xd6\x86\xd6\xda\xe0g\xf9\xd9\xa7Q\xeb\xcf\xd5=\xf1z\xde\x83\x1b\xe6\x82s\x8e=\xa1\x91\xbe\x9e\xae^/\xd8Xz\xb8\x9b\xf7>\xd7\x9e\x1f\xe9\xc0\xfc\xdb\x06`\xb1qM\x1e\xfa\xe3z\xc3\xd8\xe8\xdf\xb7\xb1i\x8eh"\xbc\x97\x16\xafI\xcf0>\xe6\xba\xee\x1cg\xdc\xe5\x8d{a\x1d\x9bn\x99v\x08c\xc2kc\r\xe1sm\xab\xf0\xd7ml\xdc?\\\xcb\xb1\x07\xc3c\xeb=\x94U\xc45\x8c\x97\xf9u\xbc/\xde\'\x17\x95\xd6\xb9\xff\x869Z\x07l\x01\xe6R{\xf2\x82\xd5\xbe\xe6\xfe\xf5\x99\xa7\xb1\x8e3\xf6\xd3\xba\x8c\xed\xaa\xe7\xc55\xf0>\xed/\xdd3\xff\x87?p\x8c\xd6\xb1\xc3\xf6\xd1\x80\xe9)\xb7\xe5\xacur\xc3\xba\xd2\x8d\xc1V\xcb\xae\x1ec\xf7\xde\x87=\xd0=\xe3Cbgu]\x8e\xe0\x92\xf5\x97\xa7\xee\x9f\'\xec\xdd\x036\x8a\xbb\xda\xef\xb1]\x82E\xa4-;\xb8\x8fp/\xb2Oz\x0e\xec\xfd\x1b\xec\xd2\x81\x9d\xaf5\xb9\xdddSp\x85\xac\xd3\x15k\x8a\x03\xdc\xf6~9\xb4F\xf8\xcc~\xde}\xc1>\xcf\x0e\xb2}\xf1\xa4_\x07\xf6\xd1\xd5c~\x8c\xfd\xc0\xf8\xc3\xf6\xe9\xf5+\xec,\xc6\x99\x0f\x8d\xe7\x81}\x97\xdd\xe0\xfd{o\xad\x87\xee\x85\xcfl;y\xb5M\x8c\x8f\xa2-\xdc6\xda\xf6\xd3v\x1a\xdb\xf9\xa4u\xe0}\x8c\xf7b\xeee{\xf4\x19\x18\x14\xbe\xef\x04\x9b\xa39\xe0\x8c`\xfc\x8ec\xdc\xae\x17\xd9\xf0\xfd2\x96\xfd\xc2\xb5}\xcd\xbd\xf8\xf91>\xe7\xe3il\xeb\xc6\xef\xf3i\xe3\xe7\xdeNY_\xd8\x13\x07\xfd\xd1e\x835\xc4:\xec5\xd4\xbeI\xeb\x19{\xf9\xca\xcf\xe7+\x07L\x03\xd6\xe4\t\xff\xe6\x1ca\xde\xf4\xda\x9d\xf3\x06\x1b\n\ -
