GraphQL-"Unknown argument \"country\" on field \"allNews\" of type \"Query\".",
GraphQL newbie here. So I was trying to write a schema in Django using graphene which will take country parameter as a String & time parameter as Character. The query works fine with the "time" parameter, but whenever I add the "country" param. it throws the following error "Unknown argument \"country\" on field \"allNews\" of type \"Query\".",.

Is it possible to do end to end testing with a Django app and React app?
We have two separate apps, one is our API which is using Django 2.2.2 and a React 16.9 app. Currently the API is very well tested, but it's not tested with our react app. What I'd like to do is, prior to merging into our develop branch, a full end to end test. So when a PR is made into develop a script will run that would launch a test server and db and then the react app would be able to use something like Cypress to test against the API. -
Working with forms in Django and checking if all the input fields are entered
I have created a contact page and there I created a form that looks like this Now I want that 'submit' button to check whether all the input fields are entered. If it is then I want to activate the Otherwise no post method activation. Instead a popup message box will appear telling that "Please enter all the fields" If post method is activated, I want to go to the {% url 'contact' %} that is my views.py file and check if the system is able to retrieve all the values from the input fields. If it does it will render a fresh contact page return render(request, 'myapp/contact.html') And popup another message box to the browser that "Form is submitted successfully" Else another message box to the browser that "There is an error occurred submitting the form" I really can't find a way to implement this. I am a newbie is Django and Python. I have very minimum experience in html and CSS. But no JavaScript, though I used a small JavaScript code, I wish to completely use Python, HTML and CSS. Is that possible to implement this scenario using my desired language? If yes, please tell me how. -
apply a filter to a child in a loop in Django
This is driving me mad (I really have looked everywhere - but I know it must be easy and I'm just being a tad think) How do I add a filter to a child of a parent (one to many)? The code below provides a list of companies in a table, then on the same page/ table, each company has a list of "charges" which is attributed to that company; thanks to the ForeignKey and using "charge_set" it works great. However, I would like to add a filter to the "charges" for status (so exclude "outstanding" status) In ROR I would have simply placed the following <% company.charges.where(status: "Outstanding").each do |charge| %> AIUI, I can't do this with Python/ Django in the view; so how would I go about adding a simple filter to the child of the parent within this loop? from django.db import models class Company(models.Model): name = models.CharField(max_length=100) class Charge(models.Model): company = models.ForeignKey(Company, on_delete=models.CASCADE) charge_id = models.CharField(max_length=100) status = models.CharField(max_length=100) from django.shortcuts import render from companies.models import Company, Charge, Filing from django.http import HttpResponse def watch_list(request): companies = Company.objects.order_by('-data_date') return render(request,'company_watch/watch_list.html',{'companies':companies}) {% for company in companies %} <tr> <td>{{company.name}}</td> <td> <ul> {% for charge in company.charge_set.all %} … -

How to change the name or alias a python module
I am using a python app, via django, that requires Pillow, and I have installed it via pip. However, when the framework loads it complains that Pillow is not installed. I can verify this when trying import pillow fails. If I look at the directory that contains the python modules I see there is no "pillow", but there is "PIL". I understand that pillow is a fork of PIL, and I can import PIL (PIL appears in a list of modules within python >>> help() >>> modules). Without touching the framework, is there a way to convince the app/django that PIL == pillow. I tried import PIL as pillow in a settings file, but that didn't solve the problem. Thanks -
is django overkill for a contact us website?
I'm a complete beginner and a relative of mine asked me to build a simple 'contact us' website for them. It should include some information about his company and a form in which people that visit the website are able to send mails to my relative. I have been playing around with vue.js in order to build the frontend. I now want to know how to put the form to send mails and I read it has to be done with backend, so I thought I could use django as I have played with it in the past and I am confident using python. Is it too much for the work that I have to do? Should I use something simpler? I accept any suggestions please, Thanks. -

Possible to replicate this form in Django?
There is a form I'm trying to figure out the best way to replicate so that I can take the data and use it to create configurations. The form however has elements in which multiple ports and server names can be associated to a single item, say the FQDN in this case. I don't know what you would call this however so I am not sure what I need to search on for a better understanding of how to recreate this. I've been learning a little about forms in Django and taking some online classes but nothing has so far covered a similar scenario, it's all just single items associated together. They say a picture is worth a thousand words, so let me show you the form I'm hoping to recreate: Questions: 1) Technically possible to recreate in Django? 2) If technically possible, is Django a good choice for doing this? 3) When it comes to the ability to associate multiple ports, servers to a single entry (FQDN) what is that called in Django/Form speak? I need something I can search to learn more about. 4) Any suggestions of where I can find related examples possibly?
