Unable to successfully use axios with React Native to make a request (IOS)
I'm unable to make a successful request with Axios. I have tested with Postman to make sure the server is correct and it works without a problem there. The error I'm getting is Network Error - node_modules/axios/lib/core/createError.js:15:17 in createError - node_modules/axios/lib/adapters/xhr.js:80:22 in handleError - node_modules/event-target-shim/dist/event-target-shim.js:818:39 in EventTarget.prototype.dispatchEvent - node_modules/react-native/Libraries/Network/XMLHttpRequest.js:574:29 in setReadyState - node_modules/react-native/Libraries/Network/XMLHttpRequest.js:388:25 in __didCompleteResponse - node_modules/react-native/Libraries/vendor/emitter/EventEmitter.js:190:12 in emit - node_modules/react-native/Libraries/BatchedBridge/MessageQueue.js:436:47 in __callFunction - node_modules/react-native/Libraries/BatchedBridge/MessageQueue.js:111:26 in __guard$argument_0 - node_modules/react-native/Libraries/BatchedBridge/MessageQueue.js:384:10 in __guard - node_modules/react-native/Libraries/BatchedBridge/MessageQueue.js:110:17 in __guard$argument_0 * [native code]:null in callFunctionReturnFlushedQueue The way I'm making my call to the backend is const onSubmit = (e) => { axios.get(`https://127.0.0.1:8080/tasks/`).then((res) => {}).catch((e) => console.log(e)); }; Am I doing something wrong in regards to axios? I don't even hit the endpoint since my print("hit")never gets logged through the phone (works with postman though) Thank you for all the help -
Is there a way in Django CBV post function to add information to context

Change query string to allow for multiple values
I have an issue with my query string, the problem is when multiple values are selected my Django search breaks. I get this in the URL ?Query=value1&Query=Value2. In this scenario, it's only the last value that is searched. What I want to happen is that both values are searched (with the equivalent of an AND operator in-between). This is the desired result ?Query=value1+Value2. I've added my search form that uses Select2 and my Django search view below. If you need anything else let me now. Any help would be much appreciated. Search form on the front end <form id="makeitso" role="search" action="" method="get"> <select class="js-example-placeholder-multiple" name="query" multiple="multiple"> <option value="Value 1">Value 1</option> <option value="Value 2">Value 2</option> <option value="Value 3">Value 3</option> </select> <script> $(".js-example-placeholder-multiple").select2({ placeholder: "Search here", }); </script> <div class="form-inline justify-content-center"> <button type="submit" class="btn btn-xlarge">Search</button> </div> </form> views.py def search(request): search_query = request.GET.get('query', None) page = request.GET.get('page', 1) # Search if search_query: search_results = TestPage.objects.live().search(search_query) query = Query.get(search_query) # Record hit query.add_hit() else: search_results = TestPage.objects.none() # Pagination paginator = Paginator(search_results, 3) try: search_results = paginator.page(page) except PageNotAnInteger: search_results = paginator.page(1) except EmptyPage: search_results = paginator.page(paginator.num_pages) return render(request, 'search/search.html', { 'search_query': search_query, 'search_results': search_results, }) -

How can I enable my html page to check the user with two boolean field value and display their data using the "if" statement?
so I've created an account and I want to display details of that account. So I've used Boolean fields to regulate the data of each account on the html page, I didn't want to use filters because the application has specific functions that I didn't want complicate it with.

Advantages and Disadvantages of using Django over Parse Server

How can I write a Django custom save method that will get or create a foreign key before saving
I have following Django models for City and State set up like this: class State(models.Model): name = models.CharField(max_length=55) abbreviation = models.CharField(max_length=2) class City(models.Model): name = models.CharField(max_length=55) state = models.ForeignKey( State, on_delete=models.CASCADE, null=True, blank=True ) I'm importing json company data that includes NAME, CITY, and STATE. It looks like this: {'NAME': 'Company Name', 'ADDRESS': '123 Main St.', 'CITY': 'Bethel', 'STATE': 'Connecticut'} I'm trying to set up a custom save method to my Company object that would get or create the necessary City object upon creating or updating the company. Creation of a City object will, in turn, require the getting or creating of a State object. class Company(models.Model): name = models.CharField(max_length=55) address1 = models.CharField(max_length=200, blank=True) address2 = models.CharField(max_length=200, blank=True) city = models.ForeignKey( City, on_delete=models.CASCADE, null=True, blank=True ) zipcode = models.CharField(max_length=20, blank=True) def save(self, *args, **kwargs): self.city, created = City.objects.get_or_create(name=city) super(Company, self).save(*args, **kwargs) Since the state field in City is not required, I'm starting with just trying to create the city. But Django is returning this error: Cannot assign "'Bethel'": "Company.city" must be a "City" instance. -
Django DRF with React: How to obtain CSRF cookie?
I have a React frontend running at frontend.example.com and a Django backend with DRF running at backend.example.com. I am using Django Session Authentication and I want to properly implement CSRF protection. Taking the React login page frontend.example.com/login as an example. It's the first time for a user to visit the page. There is a form with a user and password and on submit a new POST request is created to the Django backend. To the best of my knowledge, the CSRF token cookie should already be included in this request, right? How to obtain that CSRF token from the Django backend? I am thinking of doing a GET request to the Django backend on loading the login-page to obtain that CSRF token cookie. Is that the way to do it or is there any other best practice? -
Why am I managing two versions of a Django static file?
I'm still confused by some Django static file management and have a suspicion I'm doing something wrong/stupid. I have a core css file - /app/static/base.css But for some reason, cannot recall why, I also have - /static/css/base.css Here's everything in my settings file that I think relates to static files: PROJECT_DIR = os.path.dirname(os.path.abspath(__file__)) STATIC_ROOT = os.path.join(BASE_DIR, 'static') STATIC_URL = '/static/' STATICFILES_DIRS = ( BASE_DIR+'/other_app_1/static/', BASE_DIR+'/other_app_2/static/', BASE_DIR+'/app/static/', ) STATICFILES_LOCATION = 'static' # uncomment and run collect static before pushing to live - python manage.py collectstatic # remember to change back for when you continue to develop #STATICFILES_STORAGE = 'custom_storages.StaticStorage' I've pasted that as it might reveal why I originally started doing this, there has to be a reason. Am I correct in thinking I can stop updating /static/css/base.css and simply use the other one? I can't recall why I started, but I'm sorry to say that I still find Django static file management very confusing. -

AngularJS $recource query from DjangoREST
I have a Django RESTful API that goes with a MySQL DB and an AngularJS frontend. For one of the included Django Apps I created an AngularJS Service with a GET method in order to make queries from within an AngularJS Controller. I works so far, that I can retrieve an Array of all the Resource objects within the corresponding DB table, so I can iterate through it when I look for a specific entry. But I fear, the iterations are a waste of computational resources, so I was wondering, whether I could change the AngularJS Service in a way that it only returns the Object I am looking for. The DB table has a field called id, which is the only one that I can manage to access directly, so to speak. But I'd like to make a query for the entry with a chosen value in the field owner_id The following code shows how I have managed to get the above-mentioned Array: The Service for the mentioned App: angular.module('MyAPI').factory('App1', function($resource){ return $resource('/api/App1/:id', {id: '@id'}, { query: { method: "GET", isArray: true, } }); }); And this is from the corresponding Controller: angular.module('MyAPI') .controller('MyApp1Controller', function(App1, $sce,$rootScope,$scope,$state,$stateParams,$filter){ ...
