SQLAlchemy disconnecting from SQLite DB on Django site
On my site built with Django, I have a dashboard page that I need to display statistics about campaigns running on the site. When running the following code locally, the dashboard page loads correctly, but when running it on the live server served through Nginx and Gunicorn I run into an error. The dashboard view: def sysDashboard(request): template = loader.get_template('AccessReview/sysdashboard.html') context = {} disk_engine = create_engine('sqlite:///db.sqlite3') pio.renderers.default="svg" print(disk_engine.table_names()) sqlQueries.info(disk_engine.table_names()) df = pd.read_sql_query('SELECT emp.pid, COUNT(*) as `num_reviews` ' 'FROM AccessReview_review rev ' 'JOIN AccessReview_employee emp ON rev.manager_id=emp.id ' 'GROUP BY emp.pid ' 'ORDER BY -num_reviews ', disk_engine) print(df) fig = go.Figure( data=[go.Bar(x=df['pid'], y=df['num_reviews'])], layout_title_text='AccessReview/Reviews per Manager').update_layout( {'plot_bgcolor': 'rgba(102,78,98,0.5)', 'paper_bgcolor': 'rgba(102,78,98,0.5)', 'font_color': 'rgba(255,255,255,1)' }) overview_df = pd.read_sql_query('SELECT sys.name, ' 'COUNT(*) as `num_reviews`, ' 'COUNT(1) FILTER (WHERE reviewComplete=1) as `Completed`, ' 'COUNT(1) FILTER (WHERE reviewComplete=0) as `Incomplete` ' 'FROM AccessReview_review ' 'JOIN AccessReview_System sys ON system_id=sys.id ' 'GROUP BY sys.name ' 'ORDER BY -num_reviews', disk_engine) print(overview_df) overview_fig = go.Figure( data=[go.Bar (x=overview_df['name'], y=overview_df['num_reviews'])], layout_title_text='Campaign Overview').update_layout( {'plot_bgcolor': 'rgba(102,78,98,0.5)', 'paper_bgcolor': 'rgba(102,78,98,0.5)', 'font_color': 'rgba(255,255,255,1)' }, xaxis={'title':'System', 'fixedrange':True}, yaxis={'title':'Review Count', 'fixedrange':True}) context['overviewGraph'] = overview_fig.to_html() return HttpResponse(template.render(context, request)) Like I said, this works when running the server locally using py manage.py runserver but not when accessing the site through … -

how to call function in django template using conditionals
I have a model for Group: class Group(models.Model): leader = models.ForeignKey(User, on_delete=models.CASCADE) name = models.CharField(max_length=55) description = models.TextField() joined = models.ManyToManyField(User, blank=True) size = models.BooleanField(default=False) max_size = models.IntegerField(default=10) closed = models.BooleanField(default=False, blank=True) The idea is that Users can join groups (thus adding to the total joined for that Group) and leave groups. They do that through this view: def join_group(request, pk): id_user = request.user.id group = Group.objects.get(id=request.POST.get('group_id')) account = Account.objects.get(user_id=id_user) if group.joined.filter(id=request.user.id).exists(): group.joined.remove(request.user) account.joined_groups.remove(group) else: group.joined.add(request.user) account.joined_groups.add(group) return HttpResponseRedirect(reverse('group_detail', args=[str(pk)])) And template: {% if user.is_authenticated %} <form action="{% url 'join_group' group.pk %}" method="POST"> {% if group.closed == True %} <div>Sorry, this group is closed</div> {% else %} {% csrf_token %} {% if joined %} <button type="submit" name="group_id" value="{{group.id}}">LEAVE</button> {% else %} <button type="submit" name="group_id" value="{{group.id}}">JOIN</button> {% endif %} {% endif %} </form> {% endif %} Users joining and leaving groups works fine, the thing I'm trying to implement is when the total_joined == group.max_size a function would be called to close the group. Since, as of now the only way too close a Group is for the User who created it to go and update the Group to change closed=True. What I'm trying to do is call a function within … -
{'field': [ErrorDetail(string='This field is required.', code='required')] - DJANGO REST FRAMEWORK
I'm trying to parse the JSON data nad import it to the database through API.

How to access a website deployed on heroku from an iframe?
I created a website in Django that I deployed on heroku. It contains the following line in its settings.py file: ALLOWED_HOSTS = ['*'] This means that it allows connection with any domain name. But when I try to access a site from an iframe on an html page from my localhost, I get the following error when loading my webpage: gkwhelps.herokuapp.com refused the connection. here is the code of my iframe: <Iframe src="https://gkwhelps.herokuapp.com" width="450px" height="450px" /> I don't know why this happens because I authorized access to all hosts before deploying on heroku, I don't know if heroku has a policy about this which conditions the access to other hosts or the error comes from elsewhere. Thanks ! -
How to add new row into a table in Django Python?
The workflow of the current work is user add forms and has a selection of visit status containing approved and canceled. For example , user select visit status as approved and fill in other fields and save the form. A new row will be added in the table ClinicVisitStatusRecord() and ClinicVisitStatusHistory.Then when the user edit the form and want to change the visit status to canceled, it does not add a new row in the table ClinicVisitStatusRecord() and ClinicVisitStatusHistory and it also does not overwrite the data.

Django ManyToMany with quantity
I'm having a bit of a problem trying to model something in Django that I've conceptualized. I know that it is a many to many relationship... however it is sort of self referential and has a quantity involved. I imagine this requires a bridge model of some sort, which I have, but now how do I edit them in the admin page? What I have is a Component class. For example, a 'screw' is a component, and it requires no further components to create it. But so is a 'housing', which requires 4 screws to hold it together. That housing could then go into a manifold and the manifold could go into a vehicle and so forth. Each thing could potentially be a component of another thing if that makes sense. I've put all of the screws and bolts and such into the database through the admin edit page. But now I want to start putting in more complex assemblies. I could just create an Assembly class which has a list of one or more components. But I'm still left with the problem that this assembly could go into a larger assembly zero or more times. How do I represent … -
Django submit two forms within one view
I'm trying to submit two forms within one view. First, a user shares a URL through the first form. My program then renders some graphs and will ask the user at the end of the page to fill out a form and submit it. Here's how I'm trying to solve it: views.py: if request == "POST": if 'first-input-name' in request.POST: # or in request.POST.get('name') # do something elseif 'second-input-name' in request.POST: # or in request.POST.get('name') # do something else template: <input type="submit" name="first-input-name"/> <input type="submit" name="second-input-name"/> This is the approach I found in answers to similar questions. However, in my requests.POST I don't find the name of my input, and therefore I don't get the expected behavior. Any ideas on how to solve this? -

Django how to prevent patched method running when created in super class
I have a model with a post-save method that I don’t want to run in test: class MyModel(models.Model): def save(self, *args, **kwargs): super(MyModel, self).save(*args, **kwargs) self.post_save_method() def post_save_method(self): print("oh no!") return "real value" If I make a normal test everything works as I would expect. I can patch the method, and see that I get the mocked return value, and that the post_save_method does not run (nothing is printed from this method to the console): from django.test import TestCase from .models import MyModel from unittest.mock import patch class TestMakeObjectNormally(TestCase): @patch.object(MyModel, 'post_save_method') def test_something(self, post_save_mock): post_save_mock.return_value = "mocked value" my_model = MyModel.objects.create() print(my_model.post_save_method()) But the way the tests are set up is that the instance is created in a superclass. Following this gist I tried to patch at a class level: class BaseTest(TestCase): def setUp(self): self.my_model = MyModel.objects.create() @patch.object(MyModel, 'post_save_method') class TestMakeObjectInSuper(BaseTest): def setUp(self): super().setUp() def test_something(self, post_save_mock): post_save_mock.return_value = "mocked value" print(self.my_model.post_save_method()) This works in that the post_save_method return value is the mocked one, but unfortunately I can see that the method is running (“oh no!” is printed to the console). (I also tried patching both setUp() methods and the base class) Any advice appreciated! -

Write permission nginx gunicorn
In my django/python code I have the following lines: f = open(os.path.join(DIRECTORY, filname), 'w') f.write(filecontent) f.close() when I have DIRECTORY='/tmp/' it all works fine, the file.txt is saved with owner=root and group=www-data. However, when I want to save the file in a subdirectory of my django-project, for example DIRECTORY='/project/subfolder' the file doesn't appear, although I have that subfolder set to the same owner/group. I suspect that it is a permission problem with nginx or gunicorn. Any suggestions? I tried to solve my problem by just mounting the /tmp/ directory to the docker container where I use the file afterwards. But I ran into the problem, that files in the /tmp/ directory do not appear in docker, while as when I mount another folder like /project/subfolder/, these files do appear in docker. So either way, half works, but never both. -

When logging in, create a profile, But when logging out and then logging in with that same username, It again says to me to create a profile and creates two profiles instead of one. #For Cystomer Registration class CustomerRegistrationView(View): def get(self,request): form = CustomerRegistrationForm() return render(request,'mp/register.html',{'form':form}) def post(self,request): form = CustomerRegistrationForm(request.POST) if form.is_valid(): messages.success(request,'Congratulations Registerd Succesfuly ') form.save() success_url = reverse_lazy('profilecreate') return render(request,'mp/register.html',{'form':form}) #For Creating Profile class ProfileCreate(LoginRequiredMixin,CreateView):#ye hogia hamara upload wala model = Profile fields = ['user_name','user_ethnicity','SelectGender','user_job','user_age','mother_additionalinfo'] success_url = reverse_lazy('profile') def form_valid(self,form): form.instance.user = self.request.user success_url = reverse_lazy('profile') return super(ProfileCreate,self).form_valid(form) here are my URLs #for register path('register/',views.CustomerRegistrationView.as_view(),name= 'register'), #for CreateProfile path('profilecreate/',views.ProfileCreate.as_view(),name= 'profilecreate'), when User Created and I remove the loginrequiredmixin from profilecreateview. It give me an error of Page No Found With This Url:127.0.0.1:8000/accounts/login/?next=/profilecreate. It does not go to Profile Create View because it is not logged in but just Registered. And I want the User Go to Profilecreateview only one time. Later he can Update it. –
