Authenticate Django site with Wordpress site
I am writing a Django application and I need to sign in to it with Wordpress just like other sites can sign in with social networks. I would like my django app to provide a button that I click to take me to my wordpress site where an authenticate button or login page is waiting that redirects me back to my django site and signs me in. I will also need to have access to the wordpress user details within my django app. Does anybody know a suitable wordpress plugin and complimentary django library for such a job? -

Django: how to create_or_get excluded field in forms?
I have a form with 2 fields: one called 'field' the other called 'exclude'. 'exclude' is excluded. class ExampleForm(ModelForm): class Meta: model = Example fields = ['field', 'exclude'] exclude = ('exclude') I want to use this as part of a multi-form submit, and may or maybe already exist in Example Manager. So I wish to use get_or_create(). So I made a test for using get_or_create(), however, I am not sure whether it is the right way of going about solving the issue? def test_valid_creation(): form = self.exampleFrom(data_neg_exclude) if self.form.is_valid(): form_inst = self.form.save(commit=False) data = model_to_dict(form_inst) data.update({'exclude': 'yes please'}) Example.objects.get_or_create(**data) -
Highlight the given search string in the web page using django
I thought I could get a answer to this but couldn't :( How to highlight all the occurrences of the string the the content of the web-page using django. This is similar to the ctrl+F we usually do in the browser to search for a string. I found an answer for this in JS ,but need an answer using django here. This is my views.py to display the content of the posts.The search query would be from the "detail.html" file. views.py def post_detail(request,id=None): #retrieve the data instance = get_object_or_404(Post, id=id) if instance.draft or instance.publish > timezone.now().date(): if not request.user.is_staff or not request.user.is_superuser: raise Http404 query = request.GET.get("q") #need your help after this share_string = quote_plus(instance.content) context = { "title": instance.title, "instance": instance, "share_string": share_string, } return render(request, "detail.html", context) Waiting for an answer... :) -

NOT NULL constraint failed: Django
I'm using Django 2.0 I have a model with field to store transaction id, which is not a foreign key to any table but just a column to record the transaction id. class TransactionRecords(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE) transaction_id = models.CharField(max_length=100, default=None) But this is giving error as IntegrityError NOT NULL constraint failed: transactionrecords.authorization_id How can I setup Django not to treat transaction_id as foreign key? -
Django Rest Framework (DRF 2) Homepage Authentication
Just started with Django and DRF 2 (Sadly from 15 years of only PHP and Javascript background). Would love to see how to password-protect DRF's homepage as an example of how to get past the ViewSet confusion I am having right now (I'm used to the resource and individual routing style of Laravel). I guess I can go a bit faster learning the platform if I can see how it is done. Would also like to see how to put in additional API backends to the system, if you have time. Thanks in advanced. -
Django ModelForm foreign key filtering
I'm trying to filter foreign key field selections in my model form, but form isn't working.

Using transaction.atomic to roll back recursive form validation + save
I want to validate and save a json "tree" recursively (process_response function below). If if any leaves in the tree are invalid, I want to roll back all the saved leaves so far. Here's an example of my approach: @staticmethod def process_response(post_data): """ brief pseudocode function to illustrate resursive form.save() """ if is_leaf is True: if not form.is_valid(): return HttpResponse(status=400) else: form.save(post_data) return HttpResponse(status=200) else: # is not a leaf, so must be a branch for child_data in post_data.children result = MyClass.process_response(child_data) if result.status_code != 200: return result def post(self, request, *args, **kwargs): post_data = process_post_data(request) # json decoding, validation, etc with transaction.atomic(): try: result = MyClass.process_response(post_data) if result.status_code != 200: raise DatabaseError except: return result return result Will wrapping the call to the process_response function in transaction.atomic and raising a DatabaseError if any leaves don't validate allow me to do this? Or is there another better way of validating and saving data in a "tree" structure? -
Django Testing: django.db.models.fields.related_descriptors.RelatedObjectDoesNotExist:
I get the error from the ProductTestCase: django.db.models.fields.related_descriptors.RelatedObjectDoesNotExist: Product has no name_text It would be great to know how to fix this issue and why it only occurs when on Foreign keys. I am sure that the Department is fine it just it does not seem to be passed over to Product. I have added in Department test as well, it works fine. Thank you for your time.

Persistence issues with checkboxes
My Goal Is to create a shopping webpage where users can filter through the product selection by checking checkboxes. Instead of having a "submit" button I wanted the page to submit as soon as the user checked the checkbox. Example: the "refine by" section on Amazon. My Solution The best way would have been to use AJAX however I opted for a simple javascript / jquery function instead: $(":checkbox").change(function () { $('#product-filters').submit() }); Clicking the checkbox would correctly refresh page and apply filters, however the checkbox would appear un-checked to the user. So in Django I implemented following workaround: filters = request.GET.getlist('filters', None) selected_filters = [] try: for f in filters: selected_filters.append(int(f)) except TypeError: selected_filters = None return { # ..... 'selected_filters': selected_filters, } And then in my template: <input {% if filter.id in selected_filters %}checked="checked"{% endif %} ... all my other attrs></input> My Issue While all of the above works correctly I now have the issue that if a user clicks on a checked checkbox in order to uncheck it, it will simply refresh the page and keep it checked, with that filter applied. How should I go about fixing this? -

Vue.js in Django Templates
I am trying to use Vue.js in Django templates. One such template is the following: {% load static %} <!DOCTYPE html> <html> <head> </head> <body> <div id="myApp"> <span>Hello [[ message ]]</span> <div id="map"></map> </div> <script src="https://code.jquery.com/jquery-2.2.4.min.js" integrity="sha256-BbhdlvQf/xTY9gja0Dq3HiwQF8LaCRTXxZKRutelT44=" crossorigin="anonymous"></script> <script src="https://v1.vuejs.org/js/vue.js"></script> <script src="{% static 'js/script.js' %}"></script> <script async defer src="https://maps.googleapis.com/maps/api/js?key=AIzaSyC62HW0L7DIhL7oLbWvCEekHOkPWdxBPwk&callback=initMap"></script> </body> </html> I changed Vue's interpolation delimiters to [[ ]] to avoid conflict with Django. My script.js looks as follows: $(function() { var app = new Vue({ el: '#myApp', delimiters: ['[[', ']]'], data: { message: 'Hello, world!' } }); }); Unfortunately, the HTML rendered contains [[ message ]].

Django 2.0 url() to path()
I am currently learning Django. Until now I was working with Django 1.1 but now I am working with Django 2.0. Django 2.0 uses path() instead of url() and I don't quiet understand that. In Django 1.1 my urls looked like this: url(r'^about/$', views.AboutView.as_view(), name='about'), Now with Django 2 it looks like this path('about/', views.AboutView.as_view(), name='about'), So far so good but I just don't undertand how I can convert this url(r'^post/(?P<pk>\d+)$', views.PostDetailView.as_view(), name='post_detail'), So that it works with the new version. Just chagning url to path doesn't work, and changing url to re_path doesn't work either. Can someone help me with that Problem? Thanks in advance -

To do so, I just changed the database part on the setting.py file to : # Database # https://docs.djangoproject.com/en/2.0/ref/settings/#databases DATABASES = { 'default': { 'ENGINE': 'django.db.backends.postgresql', 'NAME': os.path.join(BASE_DIR, 'db.postgresql'), } } Now whenever I run the command python manage.py runserver 0.0.0.0:8080 (which used to work well), I get the following error : Unhandled exception in thread started by <function check_errors.<locals>.wrapper at 0x7fb91ed95ea0> Traceback (most recent call last): File "/home/ubuntu/.virtualenvs/meshine_api/local/lib/python3.5/site-packages/django/utils/autoreload.py", line 225, in wrapper fn(*args, **kwargs) File "/home/ubuntu/.virtualenvs/meshine_api/local/lib/python3.5/site-packages/django/core/management/commands/runserver.py", line 113, in inner_run autoreload.raise_last_exception() File "/home/ubuntu/.virtualenvs/meshine_api/local/lib/python3.5/site-packages/django/utils/autoreload.py", line 248, in raise_last_exception raise _exception[1] File "/home/ubuntu/.virtualenvs/meshine_api/local/lib/python3.5/site-packages/django/core/management/__init__.py", line 327, in execute autoreload.check_errors(django.setup)() File "/home/ubuntu/.virtualenvs/meshine_api/local/lib/python3.5/site-packages/django/utils/autoreload.py", line 225, in wrapper fn(*args, **kwargs) File "/home/ubuntu/.virtualenvs/meshine_api/local/lib/python3.5/site-packages/django/__init__.py", line 24, in setup apps.populate(settings.INSTALLED_APPS) File "/home/ubuntu/.virtualenvs/meshine_api/local/lib/python3.5/site-packages/django/apps/registry.py", line 112, in populate app_config.import_models() File "/home/ubuntu/.virtualenvs/meshine_api/local/lib/python3.5/site-packages/django/apps/config.py", line 198, in import_models self.models_module = import_module(models_module_name) File "/home/ubuntu/.virtualenvs/meshine_api/lib/python3.5/importlib/__init__.py", line 126, in import_module return _bootstrap._gcd_import(name[level:], package, level) File "<frozen importlib._bootstrap>", line 986, in _gcd_import File "<frozen importlib._bootstrap>", line 969, in _find_and_load File "<frozen importlib._bootstrap>", line 958, in _find_and_load_unlocked File "<frozen importlib._bootstrap>", line 673, in _load_unlocked File "<frozen importlib._bootstrap_external>", line 665, in exec_module …
