How to drag-and-drop (order) and hide columns in Django admin
I have a model and it is presented as a list in the admin panel. Im looking for the way how to allow the user to order columns by drag-and-drop, like excel or any common table viewer. Another question is how to add functionality that the user can hide/show certain columns. I know how to do in statically. Also, I found plugins on how to reorder rows in the table. But could not find any implementation for working with columns. -
Getting Django, VUE, CORS and CSRF working with a real world example
I'm really stuck. Here's what I'm trying to do. KEEP CSRF On. - please don't tell me to turn it off. I have an API app run by Django and Django Rest Framework I have a frontend app run by Vue I have installed django-cors-headers to manage CORS Everything works great localy. As soon as I move it to production, I start getting CSRF errors. Here's how everything works. I've seen answers all over that have said everything from turning off CSRF to allowing all for all the things. I want to do this right and not just shut things off and open everything up and end up with a security hole. So, here's what I have. Installed: django-cors-headers django-rest-framework drf-nested-routers ... and others I have the api running at api.websitename.com and the Vue.js app is running at websitename.com. GET requests work great. OPTION requests seem to work. Any risky request does not work. For my CORS I have 'corsheaders.middleware.CorsMiddleware', installed before my other MIDDLEWARE. Then my CORS settings are: CORS_ALLOW_CREDENTIALS = True CORS_ORIGIN_WHITELIST = ( '*.websitename.com', ) And my CSRF settings are: CSRF_TRUSTED_ORIGINS = [ "api.websitename.com", ] No matter how I play with these, I end up with a … -

Django model for a legacy table containing a custom data type
I am working with a Postgresql legacy table and found that some fields have custom data types. For example, instead of e.g. character varying, the column color has color_type as data type, with permissible options [red|green|blue|black]. Relying on the inspectdb command, the automatically generated model contains the following line and comment: color = models.TextField(blank=True, null=True) # This field type is a guess. I would "clean" this line as described in the following class, but am not sure a) if it will properly "fit" the existing table (e.g. if I write new objects inside the table), and b) whether if migrated to a new database, the custom_type would be correctly reproduced: class Things(models.Model): name = models.CharField(max_length=30, null=True, blank=True) RED = 'red' GREEN = 'green' BLUE = 'blue' BLACK= 'black' COLOR_CHOICES = ( (RED, 'red'), (GREEN, 'green'), (BLUE, 'blue'), (BLACK, 'black'), ) color = models.CharField( max_length = 10, choices = COLOR_CHOICES, default = RED, null = True, blank = True ) def __str__(self): return self.name class Meta: managed = False db_table = 'myuser' What is the proper way to reflect this custom data type in the Django model? -
How do I use a SoupStrainer for attributes that contain dashes?
I'm using Django and Python 3.7. I want to use BeautifulSoup and a SoupStrainer to look for specific elements witih attributes in my document. But how do I do that if the attribute contains a dash? I would like to do this my_strainer = SoupStrainer('a', data-id="aaa") but this results in the error Can't assign to function call complaining about the "data-id" attribute. If I change "data-id" to just "id" then everything runs, but then I don't get the results I want. -
Django: How to send csrf_token with Ajax
I have my Ajax in a jQuery function: btnApplyConfig.js: $(".btnApplyConfig").click(function(){ var token = $("input[name=csrfmiddlewaretoken]").val(); // Some other vars I'm sending properly console.log('token: '+token); //printing correctly $("#"+frm).submit(function(e){ e.preventDefault(); console.log('Post method via ajax'); $.ajax({ url: '/ajax/validate_config', type: 'POST', data: { 'token': token, //and other stuff I'm sending properly }, dataType: 'json', }); } } my Django view: def validate_config(request): token = request.GET.get('token', None) #some other vars I've sent ok with ajax data = { #some vars 'token': token, } if request.method == 'POST': item = MyClass.objects.filter(my_keyword=my_filter_values).update(my_ajax_values) return JsonResponse(data) All the data is being processed properly, the only problem for me is that I'm getting the following error: Forbidden (CSRF token missing or incorrect.): /ajax/validate_config/ I've put some prints in view in order to check if vars are being sent properly, and yes they are. How could I handle it? I checked some tutorials but I couldn't find a solution so far. -
AttributeError: 'modify_settings' object has no attribute 'wrapped' - Django LiveServerTestCase
I am getting the following error when doing a simple test. Error AttributeError: 'modify_settings' object has no attribute 'wrapped' This is my test: class FunctionalTest(LiveServerTestCase): def setUp(self): self.browser = webdriver.Firefox() def tearDown(self): self.browser.quit() def test_sample_test(self): print(f'{self.live_server_url}/login/') self.browser.get(f'{self.live_server_url}/login/') self.assertTrue(True) I am not quite sure why this is happening, but I can see the following is happening: test_sample_test seems to succeed, the browser opens and goes to the page and then closes. LiveServerTestCase.tearDownClass seems to get called twice. If I comment out the call to _live_server_modified_settings.disable() within django.tests.testcases.LiveServerTestCase.tearDownClass then the test "passes" The pytest test runner shows 6 tests found, my first 5 unit test pass fine, then test in this file shows one 'green dot' to say test passed and then and 'E' for error. So in total it looks like there is somehow 7 tests. I am using whitenoise for static file management, so I have tried to remove that in case it was interacting, but it did not change anything.

Why is my CSS file not working in Django?
I've read a bunch of other people's solution to this but can't seem to get anything to work. My CSS file in Django is not connecting to my HTML. Here is my structure: This is my CSS file: .pagination { text-align: center; margin-top: 1em; } .pagination-number { padding: 0.5em 0.8em; border-radius: 2px; color: #fff; background-color: #6D85C7; } .pagination-number:hover, .pagination-current { background-color: #3354AA; } .pagination-action { margin: 0 0.1em; display: inline-block; padding: 0.5em 0.5em; color: #B9B9B9; font-size: 1.3em; } .pagination-action:hover, .pagination-previous, .pagination-next { color: #3354AA; } .ui-menu .ui-menu-item a{ font-size: 10px; color: #96f226; border-radius: 0px; border: 1px solid #454545; } I load the CSS file in my HTML file (policy_list.html) with: {% load static %} <link rel="stylesheet" href="{% static 'css/styles.min.css' %}" type="text/css" /> But this CSS file is not being loaded when I run my Django site.

Possible to use multiple strainers wiht one BeautifulSoup document?
I'm using Django and Python 3.7 . I want to speed up my HTML parsing. Currently, I'm looking for three types of elements in my document, like so req = urllib2.Request(fullurl, headers=settings.HDR) html = urllib2.urlopen(req).read() comments_soup = BeautifulSoup(html, features="html.parser") score_elts = comments_soup.findAll("div", {"class": "score"}) comments_elts = comments_soup.findAll("a", attrs={'class': 'comments'}) bad_elts = comments_soup.findAll("span", text=re.compile("low score")) I have read that SoupStrainer is one way to improve performacne -- https://www.crummy.com/software/BeautifulSoup/bs4/doc/#parsing-only-part-of-a-document . However, all the examples only talk about parsing an HTML doc with a single strainer. In my case, I have three. How can I pass three strainers into my parsing, or would that actually create worse performance that just doing it the way I'm doing it now? -

How to create migration that alters a column from String to Foreign Key with existing data

How do I force a Python 3 Django application on AppEngine to always use https?

Edit: Yes, this question already exists, but the solution only works with Python2. -

Django: is it possible to use filter on annotated field?
For example if I want to search by first and last names of user at the same time: I tried this, but it doesn't work: qs = User.objects.all().annotate(name=F('first_name') + ' ' + F('last_name')) qs = qs.filter(name__icontains='foo bar') Is this event possible in SQL?
