How to make the DRF ( Django-REST-Framework) Token persist so that it does not get lost after each page refresh?
NOTE- I am not using Python, Django, Templates for the front end. Just Pure HTML+jQuery+AJAX I have successfully implemented getting a User Based Token from the API Backend, Set it in Header File for the subsequen requests and work on the data provided by the API. But the problem is that whenever I refresh the page, the Authentication token is not there in the Header and I have to provide credentials again to access the API. Every time I refresh the page, the token is removed. How can I stop this? This is my code for setting the Header using jQuery+AJAX. $('#login').click(function () { //Send a POST Request to the URL for Token specified for User $.ajax({ type: 'POST', data: { username: $('#username').val(), password: $('#password').val() }, url: 'http://127.0.0.1:8000/rest-api/api-token-auth/', success: function (res) { console.log(res.token) //Initialize the Ajax for the first time $.ajaxSetup({ //Set the headers so that these will be in every HTTP Request headers: { "Authorization": 'Token ' + res.token } }); }, error: function (XMLHttpRequest, textStatus, errorThrown) { alert("Error: " + errorThrown); } }); }); -

Why doesn't unittest.mock.ANY work correctly with Django objects?
I have written a test in Django, and I'm using unittest.mock.ANY to ignore certain values in a dictionary. Here is the test: from django.test import TestCase from django.contrib.auth import get_user_model import unittest.mock as mock class Example(TestCase): def test_example(self): user = get_user_model().objects.create_user(username='example') result = {'user': user, 'number': 42} self.assertEqual( result, {'user': mock.ANY, 'number': 42} ) If I run this test, I expect it to pass. Instead, I get this failure: ====================================================================== FAIL: test_example (example.tests.Example) ---------------------------------------------------------------------- Traceback (most recent call last): File "example/tests.py", line 18, in test_example 'number': 42, AssertionError: {'user': <User: example>, 'number': 42} != {'user': <ANY>, 'number': 42} - {'number': 42, 'user': <User: example>} ? ^^^^^^^^^^^^^ + {'number': 42, 'user': <ANY>} ? ^^^ Why doesn't ANY work in this case? It seems to work with strings and numbers. -
How to add custom JS to the Froala Django framework
I am using the Django implementation of Froala (https://github.com/froala/django-froala-editor/tree/master/froala_editor). This means Froala is implemented via the Django framework using views.py, models.py and forms.py rather than initialisation as an inline Javascript. In this implementation I am able to pass options to Froala via forms.py. E.g: class PageForm(forms.ModelForm): content = forms.CharField(widget=FroalaEditor(options={ 'dragInline': False, 'toolbarButtons': [['bold', 'italic', 'subscript', 'superscript'], ['indent', 'outdent', 'formatOL', 'formatUL']], })) However, if I want to implement custom events to the editor, such as this https://www.froala.com/wysiwyg-editor/examples/drop-content example of drop content, how can I do this via Django?. Usually I would add the following code, but the editor is already initialised via Django templates so it's not clear how I would proceed. <script> var dragCallback = function (e) { e.dataTransfer.setData('Text', this.id); }; // For Firefox to work. document.querySelector('#drag-smile').addEventListener('dragstart', dragCallback); document.querySelector('#drag-text').addEventListener('dragstart', dragCallback); new FroalaEditor('div#froala-editor', { events: { initialized: function () { var editor = this; editor.events.on('drop', function (dropEvent) { // Focus at the current posisiton. editor.markers.insertAtPoint(dropEvent.originalEvent); var $marker = editor.$el.find('.fr-marker'); $marker.replaceWith(FroalaEditor.MARKERS); editor.selection.restore(); // Save into undo stack the current position. if (!editor.undo.canDo()) editor.undo.saveStep(); // Insert HTML. if (dropEvent.originalEvent.dataTransfer.getData('Text') == 'drag-smile') { editor.html.insert('<span class="fr-emoticon fr-emoticon-img" style="background: url(https://cdnjs.cloudflare.com/ajax/libs/emojione/2.0.1/assets/svg/1f600.svg)">&nbsp;</span>'); } else { editor.html.insert('Hello!'); } // Save into undo stack the changes. editor.undo.saveStep(); // Stop event … -

How to hide form and show successful message on button click
I have a Django template. The template contains a table with multiple rows with each row having two columns. One column consists of videos and the other consists of a feedback form with a submit button. I wish to write a feedback and then submit it. If the feedback gets saved into the database I would like to hide the form and replace it with a successful notification. My html looks as follows: <form method="POST"> {% csrf_token %} <div class="form-group purple-border shadow-textarea" id="divFeedback"> <input type="hidden" id="spotId{{ forloop.counter }}" name="spotId{{ forloop.counter }}", value="{{ spot.id }}"> <label for="feedbackTextarea{{ forloop.counter }}">Rückmeldung</label> <textarea class="form-control z-depth-1" name="feedback{{ forloop.counter }}" rows="5" placeholder="Ihre Rückmeldung!"> </textarea> </div> <input class="btn btn-primary btn-success" type="submit" value="Abschicken" name="submit{{ forloop.counter }}"> </form> The corresponding view would be: if request.method == 'POST': if request.POST.get('submit1'): # hide the divFeedback and show 'client/success.html' return render(request, 'client/success.html') else: return render(request, 'client/spotpreview_2.html', { 'tvspots': tvspots, 'token': token }) I have already tried many answers but due to my low level understanding of HTML, I cannot do anything. Would anyone be able to help me out with this issue? -

How to work with the legacy database and integrate the django models with them?
I'am working on one of the legacy database, ran inspectdb command and got the respective models from the command. The models which are generated from django does not show-up any foreign key for the models. The db which I'am using is sqlite3. I have copied the models which was generated from inspectdb command and I tried modifying the models as per the tables in sqlite3 db. I have tried giving the 'REFERENCES' as foreign key but in migrations does not show any foreign key. I'am confused whether this REFERENCES is foreign key are not.

Django model method being called twice on production, but not on staging or local dev server
My stack: Ubuntu 18 Postgres 10 Gunicorn NGINX Django 2.1 I have a Django model method that sends an email to users if a form is submitted in a view. After deploying an update lastnight that didn't touch any of the code in the app described below, as of this morning when that form is submitted the method that sends the email is being called twice, leading to two duplicate emails being sent each time. I've started logging the tracebacks of the calls that lead to this method being called using stack_info=True and they are identical for both calls of this method (i.e. it's the method is not being called by rogue code in different places each time) a couple of hundred milliseconds apart. The logged calls are both like: File "/home/[path]/views.py", line 292, in my_view foo': _foo}) File "/home/[path]/views.py", line 231, in _process_view_helper_func thing.send_email() File "/home/[path]/models.py", line 351, in send_email stack_info=True, The confusing thing is that when I submit the form locally (Django dev server) and on my staging server (same stack and configuration as production server) the method is only called once and no duplicate emails are sent. What could be causing my Production server to be calling … -
Defined optional form field not being so optional
I looked over this topic Django: Optional model form field but didn't help solve my problem. I need the field timeout to be optional, meaning when user leaves it blank it will default to 10 This is what I've got so far: models: class MyModel(models.Model): timeout = models.IntegerField(default=10) ... ... modelform: class MyModelForm(forms.ModelForm): timeout = forms.IntegerField(widget=forms.TextInput(attrs={ 'class': 'form-control', 'placeholder': 'Enter Timeout (optional)'}), required=False, label='') ... ... class Meta: ... ... view: class CreateTestSuite(FormView): template_name = 'create_test_suite.html' form_class = MyModelForm success_url = '/list' context_object_name = 'user_id' def get_context_data(self, **kwargs): context = super().get_context_data(**kwargs) context['user_id'] = self.request.user.id return context def form_valid(self, form): form.save() # this is where form submission throws an error return HttpResponseRedirect(self.success_url) The traceback says NOT NULL constraint failed: timeout So where else do I need to specify that the form field is optional and defaults to 10 in the database if left blank ? -

How to Access and use Token Authentication and show API result at the front end in Django-REST-Framework with Ajax/jQuery/Javascript
I had been using Django and it's powerful templates for quite some time but suddenly I had to Switch to the Front End languages and technology (completely different and new) that includes JavaScript, jQuery and AJAX.

I am using Token Authentication provided to each user. How can I access the Token if I am not using Python and Django views at the front End? DO I have to login with every request? What is the actual Procedure? Can Someone Guide me through it? According to Documentations, I am supposed to put the token in header. but How would I get the Token from DB and access it for every user and with every request? -

I just started with Django today, I'm trying to get a JSON response from a certain function I have and save it all into database This is my function code: import nmap def nm_scan(ip): nm = nmap.PortScanner() nm.scan(ip, '0-65535') for host in nm.all_hosts(): print('----------------------------------------------------') print('Host : %s (%s)' % (host, nm[host].hostname()), 'State : %s' % nm[host].state()) for proto in nm[host].all_protocols(): lport = sorted(nm[host][proto].keys()) for port in lport: print('port : %s\tservice : %s' % (port, nm[host][proto][port]['product'])) I have my urls.py ready like so. urlpatterns = [ path('scan/', views.nm_scan), ] So I'm trying to understand how I would pass the parameter which would come in /scan/:ip and pass it to my function as parameter, then return the JSON data I have tried looking at some sample codes but I'm still stuck with just nonsense such as def nm_scan(request, ip): if request.method == 'POST': data = JSONParser().parse(request) # rest of the function here If someone could help me it would be great. Thanks.
