Django HTML drop-down list does not show the selected option
I have had this code working before, but now it does not show the selected option in the drop-down list. I just need an extra pair of eyes to look over this and let me know what is hiding in plain sight <form action="" method="GET" id="global_project"> {% csrf_token %} <select name="project_selector" id="ps" class="" autofocus onChange="this.form.submit();"> {% if project %} {% for project_name in projects_names %} <option value="{{ project_name|replace_space_with_underscore|replace_apostrophe_with_star }}" {% if project_name == project %} selected="selected" {% endif %} > {{project_name.name}} </option> {% endfor %} {% else %} <option name="project" value="setup">Setup a Project</option> {% endif %} </select> </form> -
IntegrityError when delete model instance
I have two models like class A(models.Model): title = models.CharField(max_length=255) class B(models.Model): recommendation = models.ForeignKey(A, related_name="+") title = models.CharField(max_length=255) When I remove the A model instance, I get something like: IntegrityError: update or delete on table "myapp_a" violates foreign key constraint "myapp_relate_recommendation_id_4a7c5340_fk_myapp_a_id" on table "myapp_b" Detail: Key (id)=(27527) is still referenced from table "myapp_b". I can't figure out why it happens, I thought FKs should be deleted by default. -
How to hide fields for specific record in django-admin?
How to hide field for specific record in djano-admin? For example if I have a model class Book(models.Model): title = models.CharField(..., null=True) author = models.CharField(...) I want to hide an author in admin panel for record with pk = 1. I found the solution as class BookAdmin(admin.ModelAdmin): list_display = ("pk", "get_title_or_nothing") def get_form(self, request, obj=None, **kwargs): if obj.pk == "1": self.exclude = ("author", ) form = super(BookAdmin, self).get_form(request, obj, **kwargs) return form It works well untill I am coming back from record with pk == 1 to other records, in this case all records in table have hided author field. -

Django service on gunicorn POST request is recieved as GET?
I have a Django rest service running on virutal environment on gunicorn server with the following .wsgi file: import os, sys import site site.addsitedir('/opt/valuation/env/lib/python2.7/site-packages') sys.stdout = sys.stderr os.environ['DJANGO_SETTINGS_MODULE'] = 'valuation.valuationcont.valuation.settings' import django.core.handlers.wsgi application = django.core.handlers.wsgi.WSGIHandler() When I do curl POST call the service works perfectly: curl -H "Content-Type: application/json" -X POST -d '{...}' -u username:password http://localhost:8000/valuation/predict/ But when I do the same request on API gateway using axios, Django service responds my custom GET response ("GET not supported, try POST"). axios({ method: 'post', url:'http://localhost:8000/valuation/predict', headers:{ "Content-Type":"application/json", "Authorization":"Basic [BASE64 ENCODING]" }, data:{ ... } }).then(response=>{ console.log(response.data) }).catch(err=>{ console.log(err.toString()) }) The request is transformed from GET to POST. This only happens with the django/gunicorn service. Since I am new to django/gunicorn I think there is something wrong with the .wsgi file. But how come the curl call then works? Any help appreciated, been struggling with this for a week now. -

Django-filter | How to render boolean field

What should I override in a FormView to insert my permissions checking?
Of its available methods, which is the ideal place to place permission checking? If get(), should it also be in the post()? The code lives in its own permissions.py and looks like this: def has_perm_or_is_owner(user_object, permission, instance=None): if instance is not None: if user_object == instance.user: return True return user_object.has_perm( permission ) It checks whether the request.user is the rightful owner of the form instance. This particular form should not be viewable to anyone else. The code I am trying to find a place to insert within the CBV, is here: can_edit = has_perm_or_is_owner( self.request.user, 'profile.fill_form', instance=obj, ) if not can_edit: raise Http404 This is usually an easy choice with, say, an UpdateView, as I'll just stick it inside the get_object(). With FormViews, this is a bit more ambiguous. Thoughts? -

Need to save estimate model in Django
I have below models.py and admin.py files in Django. I wanted to do 2 things Merge specs field of Environment and ItemObject and store into specs of Environment which I managed to do because I was able to figure out where to place the logic. (class AddEnvironmentDetailsInlineForm(forms.ModelForm)) I need to do the same for Estimate. I need to fetch the Environment.specs and Estimate.specs, merge the two and save in Estimate.specs The merge is like ItemObject -> Environment -> Estimate The challenge is that I cannot figure out where to put that logic for Estimate and Environment. Do I need to create a ModelForm for Estimate to achieve a merge? I am not clear on the logic here for the files (I am still learning the concepts in Django). If anyone could make me understand, it would be great. models.py class CommonModel(models.Model): author = models.ForeignKey('auth.User',) title = models.CharField(max_length=400) comments = models.TextField(blank=True) requirements = JSONField(default = {}) specs = JSONField(default= {}) created_date = models.DateTimeField(default=timezone.now) updated_date = models.DateTimeField(blank=True, null=True) class Meta: abstract = True def update(self): self.updated_date = timezone.now() self.save() def __str__(self): return self.title class Estimate(CommonModel): gp_code = models.TextField(default='Unknown') inputs = models.TextField(blank=True) @property def otc_price(self): environments=Environment.objects.filter(estimate=self) sum = defaultdict(list) for env in environments: … -
