Difference in API Calls in Production and Development?
Background: I have a backend server of a personal project, which makes call to a Third Party API. I have made this call in my own server instead of the React Front-End to avoid the CORS Error. Problem: When the backend is in Development, and the API call is done, it returns Correct Data. But once hosted, the API returns Incorrect Data. By Incorrect, I mean response is of same format, but main content required (which is a URL) is incorrect. I wanted to more about what difference is between the two API calls my server does, one in localhost and the other in Production. What I have figured out yet: I have used different hosting services, Heroku and Vercel, so, the Host is probably not the problem here. I have created the backend in two Tech Stacks, Django and Node - Express, so that also checks out, as both return same incorrect Data in Production, whereas, both return Correct Data in Development. Hence, I wanted to know about what data does API calls send over as request headers etc. and the difference between them when done in Development and Production. Here's the Express Code: const express = require('express'); const … -

Django-CMS : Unexpected keyword argument 'providing_args'
I have installed a vanilla django-cms on a new server. I installed all requirements. It all went fine, up untill the point where I wanted to migrate to the database (Postgres). So this is what I did : Tried reinstalling and installing it all again. Didn't change it. Used google to try and find people with the same error. Try editing the signals file on which the error(shown below) fires, but that meant rewriting it all, which still made it unresponsive.

javascript isn't reading correctly a static json file
I have been working on a project, where I have to get data from a database with its own server. For that I have used Django as a tool to combine both backend and frontend. Also I created a function that connect python to odbc so I can get the information from the database. My logic was that I want to convert all the information into JSON file, so that javascript (frontend) would have acccess to it to convert it into graphs. To make myself more clear, here are the main components: views.py def get_name(request): # if this is a POST request we need to process the form data if request.method == 'POST': # create a form instance and populate it with data from the request: form = TextForm(request.POST) # check whether it's valid: if form.is_valid(): # From this we get the result of POST method date = form.cleaned_data['date'] splitdate = date.split(sep='-') # Here we call the class created in Functions.py x = GetData(int(splitdate[2]), int(splitdate[1]), int(splitdate[0])) x.getInfo() context = { 'text': date, 'form': form, } return render(request, 'index.html', context) # if a GET (or any other method) we'll create a blank form else: form = TextForm() return render(request, 'index.html', {'form': … -

How do I dynamically filter fields returned in django rest api get request based on the user making the request?
I have a photoshoot api that allows photographers to post shoot photos from which preview and watermarded versions are derived.

Work around for handling CPU Intensive task in aws ec2?
I have created a django application (running on aws ec2) which convert media file from one format to another format ,but during this process it consume CPU resource due to which I have to pay charges to aws. I am trying to find a work around where my local pc (ubuntu) takes care of CPU intensive task and final result is uploaded to s3 bucket which I can share with user. Please note :- I have decent internet connection and computer which can handle backend very well but i not in state to pay throttle charges to aws. Solution :- One possible solution is that when user upload media file (html upload form) it goes to s3 bucket and at the same time via socket connection the s3 bucket file link is send to my ubuntu where it download file, process it and upload back to s3 bucket. Please suggest me better solution as it seems to be not efficient. -

django-treebeard Materialized Path tree depth ended up being zero
I found a problematic node with id 633. tree.find_problems() ([], [], [], [633], [35, 9, 50, 291, 464]) After running tree.fix_tree() It does not find any problems. tree.find_problems() ([], [], [], [], []) But actually 633 is still in some wierd state. >>> node633.depth 0 >>> node633.path '' Problem: node633.depth is 0 which means its not root but it does not have parent as well. Path is empty too. This means my code will try to find parent from a node that does not have a parent. Running fix_tree again does not fix it. Moving node633 is not an option too because: treebeard.exceptions.InvalidMoveToDescendant: Can't move node to a descendant. Question: How can i fix this broken node66? -

I am looping through the response and displaying the data in a table. <tr *ngFor="let item of job_list"> <td style="text-align:center">{{item?.ReleaseName}}</td> <td style="text-align:center">{{item?.Source}}</td> <td style="text-align:center"><mat-icon *ngIf="Successful" style="color:green;">check circle icon</mat-icon> <mat-icon *ngIf="Faulted" style="color: red;">error icon</mat-icon> <mat-icon *ngIf="Stopped" style="color: grey;">cancel icon</mat-icon> {{item?.State}} </td> <td style="text-align:center">{{item?.StartTime | date:'dd-MM-yyyy HH:mm:ss'}}</td> <td style="text-align:center">{{item?.EndTime | date:'dd-MM-yyyy HH:mm:ss'}}</td> </tr> Here, I want to display mat-icon based on {{item?.State}} value. For example if the value is Successful, I want to display the "check circle icon", if it's "Faulted", I want to display "error icon" etc. Is this possible? Thank you -

Django: How to log user in right after they had registered with somewhat default UserCreationForm?
I'm trying to log the user in right after they had registered with the app, so that they don't have to manually log in right after. I have created RegisterForm from django's UserCreationForm and it works as it should - it creates an User object if the form is valid, but I don't know how to access that created User object to log it it using the login function, which requires, aside from request, also an user object. Note: I have edited the default User in models.py. This is my code: class RegisterForm(UserCreationForm): def __init__(self, *args, **kwargs): super().__init__(*args,**kwargs) self.fields['username'].widget.attrs.update({'class':'form-control','id':'username', 'aria-describedby':'usernameHelp'}) self.fields['password1'].widget.attrs.update({'class':'form-control','id':'password1', 'aria-describedby':'password1Help'}) self.fields['password2'].widget.attrs.update({'class':'form-control','id':'password2','aria-describedby':'password2Help'}) class Meta: model = User fields = ['username', 'password1', 'password2', 'email', 'first_name', 'last_name', 'photo', 'amazon', 'twitter', 'facebook', 'instagram', 'youtube'] widgets = { 'email':EmailInput(attrs={'class':'form-control', 'id':'email', 'aria-describedby':'emailHelp'}), 'first_name':TextInput(attrs={'class':'form-control', 'id':'first_name',}), 'last_name':TextInput(attrs={'class':'form-control','id':'last_name', 'aria-describedby':'nameHelp'}), 'photo':ClearableFileInput(attrs={'class':'form-control','id':'photo', 'aria-describedby':'photoHelp'}), 'amazon':URLInput(attrs={'class':'form-control', 'id':'amazon', 'aria-describedby':'amazonHelp'}), 'twitter':URLInput(attrs={'class':'form-control', 'id':'twitter', 'aria-describedby':'twitterHelp'}), 'facebook':URLInput(attrs={'class':'form-control', 'id':'facebook', 'aria-describedby':'facebookHelp'}), 'instagram':URLInput(attrs={'class':'form-control', 'id':'instagram', 'aria-describedby':'instagramHelp'}), 'youtube':URLInput(attrs={'class':'form-control', 'id':'youtube', 'aria-describedby':'youtubeHelp'}) } And here is the view: def register(request): # POST if request.method == "POST": # In addition to our form we must make sure to get the files too, if photo is uploaded form = RegisterForm(request.POST, request.FILES or None) if form.is_valid(): form.save() #user = User.objects.get() ??? #login(request, user) return HttpResponseRedirect(reverse('index')) else: … -
Can't mock a third party api call
I have a view that perform a third party API call: from .atoca_api_calls import atoca_api_call def atoca_api_call_view(request): # some code data = atoca_api_call(**params) # the actual API call happens in this func # some code My intention is to mock just the atoca_api_call() func and not the whole view. class AtocaTestCase(TestCase): def setUp(self): # some code @patch('crm.atoca_api_calls.atoca_api_call') def test_atoca_call(self, mock_atoca_api_call): mock_atoca_api_call.return_value = MagicMock( status_code=200, response=some_json # just returns some json ) url = reverse('crm:atoca-api-call') # url related to `atoca_api_call_view` response = self.client.post(url, some_others_params) # various asserts The test works fine but atoca_api_call() is not mocked. I'm aware of where to patch: @patch('crm.views.atoca_api_call', autospec=True) Raises a ValueError: ValueError: Failed to insert expression "<MagicMock name='mock.__getitem__().__getitem__().__getitem__()().resolve_expression()' id='140048216397424'>" on crm.Company.atoca_id. F() expressions can only be used to update, not to insert. It's probably a simple issue I don't catch for inexperience, any help is really appreciated.
