Testing Django DRF API endpoint giving an unexpected 404 with GET request
I have a DjangoRestFramework setup and it works fine, but I'm trying to wrangle it under tests. I use FactoryBoy in order to create the objects in the setUp and can confirm they exist because when I query for them they return without issue. I've written out my test like this: class AssignmentTest(APITestCase): def setUp(self): # Create the assignment from the AssignmentFactory # this works without issue f.AssignmentFactory() self.factory = APIRequestFactory() self.client = APIClient() self.url = reverse('Assignments-list') # accessing self.url in a browser shows data as expected but fails in test print(self.url) # returns: '/api/myapp/assignments' self.root = ('/api/myapp/') def test_api_endpoint_returns_200(self): """ Ensure then endpoint gives a 200 response. """ response = self.client.get(self.root) print(response) # Gives 200 and works fine other_response = self.client.get(self.url) print(other_response) # Gives 404 - but I can't figure out why self.assertEqual(other_response.status_code, 200, 'Expected Response Code 200, received {0} instead.' .format(other_response.status_code)) In my rest_api.py file in my app I have listed: router = routers.DefaultRouter() router.register(r'assignments', AssignmentViewSet, basename='Assignments') If I do python manage.py runserver and go to the API endpoint (api/myapp/assignments) it shows the results as expected. But it continuously gives me 404 in my test. Am I setting something up wrong here? The root URL works and gives … -

How to get a second field in query_set?
I have a model called 'Report', the model has two fields 'area' connected with ForeignKey to another model called 'Area' and 'country' connected with ForeignKey to another model called 'Country'. Also I have a dropdown button, for the 'area' field and it supposed to take me to a page where the list of countries belong to the area supposed to show up from the 'country' field. My model str returns 'area' field. Because str return 'area' field my 'country' page also showing list of areas instead of list of countries. I tried 'return '{} {}'.format(self.area, self.country). When I do that my 'area' dropdown shows both area and country. Example 'NORTH AMERICA CANADA'. So tired to get 'country' field in a different way. country = Report.objects.filter(country=country). But I get error country is not defined. My models.py: class Report(models.Model): author = models.ForeignKey(User, on_delete=models.CASCADE) church_name = models.CharField(max_length=255) area = models.ForeignKey(Area, on_delete=models.CASCADE, null=True, blank=True) country = models.ForeignKey(Country, on_delete=models.CASCADE, null=True, blank=True) water_baptism = models.IntegerField(default=0) holy_ghost = models.IntegerField(default=0) def __str__(self): return '%s' % self.area def get_absolute_url(self): return reverse('users:report_view') my views.py def report_list for 'areas' dropdown button @login_required def report_list(request): areas = Report.objects.all() context = { 'areas':areas, } return render(request, 'users/report_list.html', context) def report_countries for 'countries' dropdown … -
Django on Heroku - add new models to postgreSQL database
I have an Django 2.1 / Python 3.6 application running on Heroku's hobby account. The first version of this deployment went smoothly. Now I needed to add more fields to existing models and also add additional models from my local setup (which is running very smoothly with the changes) to Heroku. I do the usual git push heroku master to get the new code over to Heroku. Then I do both heroku run python manage.py makemigrations heroku run python manage.py migrate The first step gives me Running python manage.py makemigrations on ⬢ hirt-family-v4... up, run.3753 (Free) Migrations for 'users': users/migrations/0005_auto_20190425_1452.py - Create model XtraPhotos - Add field phone_number to person - Add field parent to xtraphotos which is fine, but the migrate is also coming back with the message Running python manage.py migrate on ⬢ hirt-family-v4... up, run.5929 (Free) Operations to perform: Apply all migrations: account, admin, auth, contenttypes, sessions, sites, users Running migrations: No migrations to apply.

Django: Redirect 'Admin logout' to 'Admin login' page
In my Django App settings I've mentioned the following 2 lines in settings.py, it works fine for the normal user but is not good enough for the Admin. LOGIN_REDIRECT_URL = '/my_app/profile/' LOGOUT_REDIRECT_URL = '/my_app/login' When I log out from the Admin, it takes me to the login page of the user, as mentioned in the above LOGOUT_REDIRECT_URL. What I want is that admin logout redirect should go to the Admin login page, not the user login page. snippet from urls.py path('admin/', admin.site.urls), Can anyone suggest the best way to deal with this issue? -
Server isnt recognizing python virtualenv anymore
I have a deployed Django app on a Centos 7 server. I ran into problems when git pulling from my repository. It doesn't recognize python-home at the location where my virtualenv is anymore. When i print(sys.prefix), it shows '/usr', but when i activate my virualenv (source /path/to/virtualenv/bin/activate) it shows the correct path that is assigned to python-home in my httpd .conf file .conf file Alias /static /var/www/ek/static <Directory /var/www/ek/static> Require all granted </Directory> <Directory /var/www/ek/new> <Files wsgi.py> Require all granted </Files> </Directory> WSGIApplicationGroup %{GLOBAL} WSGIDaemonProcess ek python-path=/var/www/ek python-home= /var/www/kpi_env WSGIProcessGroup ek WSGIScriptAlias / /var/www/ek/new/wsgi.py I'm not exactly sure what the problem is, when im not in my virtualenv, should the prefix be the path to the virtualenv? Should print(sys.prefix) only show var/www/kpi_env when im in the virtualenv? Whatever it is, it doesn't recognize python-home=/var/www/kpi_env as anything anymore. When i change it to python-home = /usr it works but the application is giving me errors that i've never run into before on my server or on my workstation. This error being Permission denied is Server running on host 12.0.0.1 and accepting tcp con on port 5432 This is referring to postgresql, and i'm sure that it is running and accepting tcp … -
Using OAuth2 Gmail tokens to access protected sources
I'm having trouble figuring out how to use the tokens I got to create a new OAuth2 session and access the Gmail API. I created an app that uses the Gmail API. After the Oauth approval flow I save for each user their google user id, the access and refresh tokens, the id token and the date when the token expires. I now have a task that has to sync some data and access the Gmail api. Adding the token to the OAuthSession isn't working. import os from requests_oauthlib import OAuth2Session from oauthlib.oauth2 import TokenExpiredError def sync_gmail(user): client_id = os.getenv('CLIENT_ID') refresh_url = "www.googleapis.com/oauth2/v4/token" client_secret = os.getenv("CLIENT_SECRET") redirect_uri = os.getenv("REDIRECT_URI") authorization_base_url = "https://accounts.google.com/o/oauth2/v2/auth" token_url = "https://www.googleapis.com/oauth2/v4/token" scope = [ "https://www.googleapis.com/auth/gmail.metadata", "https://www.googleapis.com/auth/userinfo.profile" ] google_credentials = get_user_creds(user) try: client = OAuth2Session(client_id, token=google_credentials.access_token, scope=scope, redirect_uri=redirect_uri) r = client.get('https://www.googleapis.com/gmail/v1/users/' + google_credentials.google_user_id + '/profile') print(r) except TokenExpiredError as e: token = client.refresh_token(refresh_url, **extra) -

Enumerate related objects through a many-to-many
I know that this question seem to have been answered several times, but none of the answers I found really gave me any pointer to the issue I am facing. I have 3 models into a django application: class Person(models.Model): name = model.CharField(...) interests = models.ManyToManyField(Topic, through="Interest") class Topic(models.Model): key = model.CharField(...) class Interest(models.Model): person = models.ForeignKey(Person, on_delete=models.CASCADE) topic = models.ForeignKey(Topic, on_delete=models.CASCADE) comment = models.CharField(...) The views.py is declared as follow: class IndexView(generic.ListView): template_name = 'index.html.j2' context_object_name = 'people_list' def get_queryset(self): return Person.objects.all() And the index.html.j2 looks as follow: {% for person in people_list %} <tr> <td>{{ person.name }}</td> <td> <ul> {% for interest in person.interests.all %} <li>{{ interest }}</li> {% empty %} No interest found {% endfor %} </ul> </td> </tr> {% endfor %} Surprisingly, the view returns 'No interest found' for every person when the admin site clearly shows interests for all persons. It looks like the Person.objects.all() in the views.py did not load the related objects from database. -
How can I use model objects as Django checkbox options and then save selections in an iterable way?
I am trying to create a scheduling site and to do that I need to allow the user to select which jobs are to be schedule. Jobs are predefined by the user and thus are already saved in my Django Model. I have been able to get the job titles to show as checkbox options but how do I save which options (when multiple have been selected) have been selected so I can use only those jobs during scheduling. I have been told to use ManyToManyField but I am unsure if I have used it correctly. class Job(models.Model): Job_Name = models.CharField(max_length=100) Completion_Time = models.IntegerField() user = models.ForeignKey(User) def __str__(self): return self.Job_Name class Selection(models.Model): selection = models.ManyToManyField(Job, blank=True) class SelectForm(forms.ModelForm): choices = forms.ModelMultipleChoiceField( queryset = Job.objects.all(), widget = forms.CheckboxSelectMultiple) class Meta: model=Selection fields=("selection",) class SelectJobView2(TemplateView): template_name="job_select.html" def post(self, request): form = SelectForm(request.POST) if form.is_valid(): meal = form.save(commit=False) meal.save() return render(request, self.template_name, {'form' : form,}) def get(self, request): form = SelectForm() return render(request, self.template_name, {'form' : form,})``` I want all of the selections to be saved in the Selection model so i can then use those the job object when scheduling. -
Reference python global variable defined in a function --> from another file
I am using django social auth pipeline to introduce a custom function during the social authentication process. I am able to parse the request parameters (eg: the facebook user token) inside this function. The parsed token will serve as input for another function located in another file and here stands the problem: I can not use it in another function I need to reference the global token variable from another function in another file. When I merge file1.py and file2.py , it works but when I want to use the parsed token from createUser(...) of file1.py in function doSomething() of file2.py, the interpreter throws an error which says that function createUser comes with arguments and I must define them , but how? # settings.py: SOCIAL_AUTH_PIPELINE = [ ...

How to submit form in django at a scheduled time?
I have a typical form: class ScanForm(form.ModelForm): """ Creating a form for Scan results """ value = forms.DecimalField(widget=forms.NumberInput( attrs={ 'class': 'form-control', 'placeholder': 'Value', 'max': '500', } )) count = forms.DecimalField(widget=forms.NumberInput( attrs={ 'class': 'form-control', 'placeholder': 'Amount', 'max': '400', } )) class Meta: """ Adding choice of interval and exclude unused fields """ model = ScannedValue exclude = ('scan_date',) widgets = { 'interval': forms.Select( attrs={ 'class': 'form-control', }), } I'm rendering that form in my index.html file as usual. And it's working normally when I put all the data and pushing "Submit" button. But what I need is to automatically submit this form with filled values (let's say for 'value' = 5, 'count' = 10) at certain time, let's say 01:00pm every day. Then I need to parse all received data with function in my views after submitting the form and then save the results to database. What is the best and most right way to do this? -

Django deployed in IIS is not working with Selenium

Check if element from list is inside another list in django template
I'm making a for loop through a list. For each element in this list, I would like to know if this element could be egal to one of 4 words from another list. This is my example in order to describe the situation: From my view: content = ['**Added**:\n', '* something (toto-544)\n', '\n', '**Changed**:\n', ...] operations = ['Added', 'Changed', 'Fixed', 'INTERNAL'] From my HTML file: {% for line in content %} {% if line in operations %} <tr class="table-subtitle"> <td colspan="12">{{ line }}</td> </tr> {% else %} <tr class="table-value-content"> <td colspan="12">{{ line }}</td> </tr> {% endif %} {% endfor %} It should display the first line element different than the second one (I changed color between both classes). Because line[0] is in operations and not line[1]. Do you have any idea why it doesn't work through my for loop/if statement ? -

Confusion in switching from Java Spring to Python Django framework
I have 1+ years of good experience in Core Java, JEE, Spring Framework, Hibernate. I can handle enterprise level applications as well. But from the past 3 months, I am working with Python Django(v2.2) framework and developed an application similar to Olx(buy and sell). I found it is having almost all web development components(ORM, admin, internationalization, etc.) i.e. we can say it is full-stack web development framework even support bootstrap in its core and because of python we no need to write lengthy code. Now I am in confusion that should I take a very deep dive in Django for a bright future or should come back to Java platform again? When I search for a job I found that there are fewer jobs in Python Django as compared to Java. As Django Came into the picture from 2005 and Java from 1995 so this could be the reason for more jobs in Java. Please anybody expert can guide me in this direction? -
