Django datetime format different from DRF serializer datetime format
I am trying to understand why this is happening. I have a Django DateTime field and Django Rest Framework serializer that uses the field. I am trying to compare the dates for both of them and get the following results from JSON endpoint and model result: DRF: 2018-12-21T19:17:59.353368Z Model field: 2018-12-21T19:17:59.353368+00:00 Is there a way to make them similar? So, either to make both of them be "Z" or "+00:00." -
How to make a query to get only the data from each user
I have a query using 3 tables. The law, article and marked. I have a website where the user can choose one law to read all the articles. For each article, the user can marked it or type some description for this article. The marker and description is saved on the marked table. So, when the user open his law again, all his markations and descriptions will be loaded. The problem is that in my query, I dont know how show the descriptions and markations of the user logged in. My query is showing the descriptions and markations for all users registered in marked table. An example of marked table content: id is_marked description article_id law_id user_id "0" "0" "test1" "1100" "3" "1" "1" "0" "test2" "1102" "3" "1" If I access the law = 3 with the user_id =2, all the description of the user_id = 1 is showing. My query: law = get_object_or_404(Law, pk=pk) articles = Article.objects.filter(law=pk) articles = ( Article .objects .filter(law=pk) .annotate( is_marked=Exists( Marked .objects .filter( article_id=OuterRef('id'), usuario=request.user, is_marked=1, ) ) ) .annotate( description=(F('markedLaw__description')) ).order_by('id') My model: class Law(models.Model): name = models.CharField('Nome', max_length=100) description = models.TextField('Description', blank = True, null=True) class Article(models.Model): article = models.TextField('Article') id_article_law … -

django request.POST.getlist is empty sometimes... when it shouldn't be
I have a list in a form on an html page: <label for="group_add_insurance">Click on name to remove </label> <div class="col-md-12"> <select id='group_add_insurance' name='group_add_insurance' class='form-control' size="5" multiple='multiple'> {% for ins in associated_insurances %} <option value="{{ ins.value }}">{{ ins.label }}</option> {% endfor %} </select> </div> Simple stuff, there is some javascript that if you search for an insurance and click add it will add it to the list with a simple jquery append. If i submit this form, this list in the view has stuff in it: print request.POST.getlist('group_add_insurance') Has stuff! If you click on the list where we remove an item via this: $('#group_add_insurance').change(function(){ if (confirm('Are you sure you want to remove this?')) { // Save it! $('#group_add_insurance option:selected').remove(); alert($("#group_add_insurance option").length) //just testing sanity } else { // Do nothing! alert($("#group_add_insurance option").length) //just testing sanity } }); It indeed removes the right thing! The lengths of the list also confirm the remove didn't get over zealous and the right number of items exists. But if you ever do a remove, and click submit, the print request.POST.getlist('group_add_insurance') Comes back totally empty?! even if you just remove one item. for completeness the javascript to add to the list $('#group_add_insurance').append( $("<option></option>") .attr("value",$("#insurance_search_name_id").val()) .text($("#insurance_search_name").val()) ); … -

Overriding Django Default Authentication Form
I am trying to override the canned error message for the Django AuthorizationForm. Instead of it saying this field is required I am trying to get it to say Username is required. I have tried to subclass the AuthorizationForm with the standard LoginView and it doesn't pick up my custom clean method. I looked at this SO similar issue, Change default django error messages for AuthenticationForm and tried to follow the tips in there but still can't get it to work. Thanks in advance for any tips on what I might be doing wrong. class AuthenticationForm(AuthenticationForm): def __init__(self, *args, **kwargs): super(AuthenticationForm, self).__init__(*args, **kwargs) def clean(self): cleaned_data = super(AuthenticationForm, self).clean() username = cleaned_data.get('username') password = cleaned_data.get('password') if username and password: pass else: self.add_error('username','Username and Password required.') pass I am trying to get it to show Username and Password Required instead of the canned default This field is required messages. No matter what I do I can't seem to get it to pick up my code above. I have it stored in my project forms.py file. I believe I'm subclassing it incorrectly. I've tried a lot of different combinations but can't seem to get it see this form. I'm running Django 1.11 -

Rendering Django view via ajax request
Currently using ajax to monitor a long running task in a Django application. While the task runs, a progress bar is displayed, and when it finishes I'd like the ajax to make a request and load a view with the results, to render a page for the user displaying these results.

Deployment requirements Django App on AWS
I think I have drastically underestimated my know-how for hosting a website with Django. I think I'm now at a point where I understand what parts all the pieces play, but I want to double check that knowledge. The goals / desired features of my website are: Registration / Login features Static files are served reasonably well Users are able to upload images for profiles / avatars (media files) Sections of the page automatically reload Data is stored in and accessed from the database The website is tied to my domain The main app is basically a chat room with non-numerical dice rollers, where users create very simple profiles and can use different images and names (avatars) in different rooms. Of course, I am trying to do this for as little money as possible. This is (currently) a hobby / learning thing, not a business venture. I am not expecting high traffic / that is not the main concern for launch (but, of course, I know I should be thinking about scalability). I have been able to develop the app / site on localhost. But, when it comes to production, I am really coming up against my lack of knowledge. … -

How to run Django units test with default and unmanaged database?
I have a Django project with a default database used for storing things like user, orders etc. We also have an unmanaged database. Now when you run Django test they try to make test databases, but since we have an unmanaged db we cannot do this. I cannot create migrations of this db since that will land 300 errors about clashing reverse accessor. We use Docker and automatically spin up this unmanaged database and fill it with some mock data. This one is used for development and such. I would like the unit test to use this one for testing. I tried things like creating migrations but since the reverse accessor issue this is not possible. Is there a way to use the unmanaged database for unit testing? The test_default database which Django creates is fine, but I cannot create a test_unmanaged database. -
Problem by adding truncateworld and safe tags
I use Django 1.11 for my blog. I illustrate all acticles in my first page by a title, an image and a few words. For the few words, I'm using this method : {{post.text|safe|linebreaks|truncatewords:"50"}} I use a text editor and sometimes, I use for example italic text : <i/>Italic text</i> Let's imagine the value of truncatewords is on "1". It means it returns : <i/>Italic There is my problem. Some HTML tags are still opened. It means that the italic text never end and It will be applied for the rest of the code. Do you know if a trick or workaround exists ? Thank you. -
