Text editor summernote for admin panel Django loading very slowly
I have an Enterprise model and there are more than 60 fields in this model, Summernote-Django has been added to the text editor. In my case, 25 fields in one model have been added to the text editor by the Summernote-Django, the problem is that this model on the admin panel is very, very slow to load. How can I optimize Summernote-Django? I added 'lazy': True to the settings, but it didn't help.Perhaps you would recommend another library for adding text editors to the django administration more optimized? Here is a screenshot on the Enterprise page, on dev tools shows that more than 100 js/jQuery files are being uploaded from Summernote-Django -
Multiple templates in a single Listview
I have some ListViews implemented seperately with different template_names with similar model,How can i use implement them in one single List view that can take multiple templates?

What is the difference in using Django Rest API vs django.contrib.auth to build a login/logout app
I am new to Django and I want to build a login and logout for a chat app I am making which I plan to deploy eventually. From the online tutorials I see, there are some that use the Django Rest API framework, and some use the pre-installed django.contrib.auth Is there any difference in choosing which to use? -
Trying to stay DRY in Django: Refactoring repetitive code in Views
I have a lot of different list views for tables. Each view differs only in the template used. My only successful strategy involves using a decorator containing the common code and then returning 'pass' for the view function. The problem I face is if I want to add individual code to a specific list view that differs from the others. Is there a better way of doing this? Here is my decorator: def my_decorator(html=""): def my_decorator(*args, **kwargs): def wrapper(request, *args, **kwargs): bacteria = Bacteria.objects.all() bacteria_count = bacteria.count() bacteriaFilter = BacteriaFilter(request.GET, queryset=bacteria) bacteria = bacteriaFilter.qs remaining = bacteria.count() common_tags = Bacteria.tags.most_common()[:8] ''' context = {"bacteria": bacteria, 'common_tags': common_tags, 'bacteria_count': bacteria_count, 'bacteriaFilter': bacteriaFilter, 'remaining': remaining} ''' return render(request, html, locals()) return wrapper return my_decorator And here are several examples (I have over 15 tables) of the list view functions: @my_decorator(html="bacteria/generalPhysiology.html") def general_physiology_view(request): pass @my_decorator(html="bacteria/enzymeActiveTable.html") def enzyme_activity_table_view(request): pass -
Django autocomplete light Select2 widget not appearing
I have been following the DAL tutorial and can access a json object at http://127.0.0.1:8000/entry/river-autocomplete/?q=S So i know my view is working.

How to disable access to a django APIs based on is_active boolean field?
I have an author's model with a field: is_active = models.BooleanField(default=False) I wish to restrict access to the author whose is_active=False. I can use something like this in every api: get_object_or_404(uuid=id, is_active=True) But I wish to globally restrict access to the UUID whose is_active=false, instead of actually writing this statement in every api. Is there a way I can do that? -
Django Rest Framework nested relationship performance on SerializerMethodField
I have been looking for an answer but get none. This is the situation: I have 3 models defined like this: class State(models.Model): name = models.CharField(max_length=150, null=False) code = models.CharField(max_length=5, null=False) class City(models.Model): name = models.CharField(max_length=150, null=False) code = models.CharField(max_length=7, null=False) state = models.ForeignKey(State, related_name='cities', on_delete=models.RESTRICT) class Home(models.Model): code = models.CharField(max_length=25, null=False city = models.ForeignKey(City, related_name='homes', on_delete=models.RESTRICT) The response that the people needs on homes is something like this [ { "code": "10011", "city": "Municipio 1", "state": "Departamento 1" }, { "code": "10012", "city": "Municipio 1", "state": "Departamento 1" } ] I was able to create that response doing this with the serializer: class HomeSerializer(serializers.ModelSerializer): city = SlugRelatedField(slug_field='name', queryset=City.objects.all()) state = SerializerMethodField() class Meta: model = Home fields = ['code', 'city', 'state'] def get_state(self, obj): return obj.city.state.nombre But Im not sure if this is the right way to do it, home is a table that is gonna grow up a lot (maybe 1M+ rows), and I am thinking that this solution is gonna hit the database multiple times. Now I know that I can add filtering and pagination, but I am concern about the performance of this solution. I also tried with depth = 2 but they hated it. I've … -
How to change the renaming pattern when there are duplicate files
Let's say I upload a file to my Django App (A.pdf) Over time I realize that that file contains an error. I want to upload that file back to my website and keep the old file, but I want the file name to change to A(1).pdf I implemented a drag & drop system with Dropzone.js and everything is working but, when a file is duplicated the system assigns new names randomly. This is an example: How can I get rid of the _QXjmarl string and replace it with (N) pattern? E.g. (1), (2), (3)...(45), (N) Dropzone.js: var Drop = Dropzone.options.DidDropzone = { autoProcessQueue: false, //stops from uploading files until user submits form paramName: "filename", // The name that will be used to transfer the file maxFilesize: 1024, // Maximum size of file that you will allow (MB) clickable: true, // This allows the dropzone to select images onclick acceptedFiles: '.psd, .csv, .doc, .docx, .xls, .xlsx, application/csv, application/docx, application/excel, application/msword, application/pdf,application/vnd.ms-excel, application/vnd.msexcel, application/vnd.openxmlformats-officedocument.spreadsheetml.sheet, text/anytext, text/comma-separated-values, text/csv, text/plain, image/*, video/*,', //accepted file types maxFiles: 20, //Maximum number of files/images in dropzone parallelUploads: 20, previewTemplate: '<div class="dz-preview dz-image-preview">'+ '<div class="dz-image">'+ '<img data-dz-thumbnail />'+ '</div>'+ '<div class="dz-details">'+ '<div class="dz-filename"><span data-dz-name></span></div>'+ '<div class="dz-size" data-dz-size></div>'+ '</div>'+ … -
On adding a Model using the Admin Panel in Django, is there a way to implement altering other Models?
I am using the standard Admin Panel in Django that has a Model, Product, that contains its information. the Product has a TextField() Summary of words. I would like to implement a Keyword model that has a single word. The idea is that the Keyword would be applied to multiple Products if the Product has the Keyword's word in its Summary. I am trying to implement that when the Admin in the Admin panel adds a Keyword model, the server would automatically assign each Product that Keyword. The issue is that I do not know how to edit the Admin Panel's add function to edit other models upon adding one model. My current understanding in Django is that you could create a custom view to add a Keyword, but I would like to have the option to implement it in the Django Admin Panel as well. -

Django: timezone conversion inside templates

Django and HTML- how to apply styling to specific answers

Can django-tenants work for project that has a general section and company accounts
I working on a project that will have a main section where the users will have access to sections common to all (for example forums where they can communicate) and company accounts that will only be accessible to those that are members of that account. I have set up django-tenants but I am finding that out of the box it does not seem to work as I thought it would. For example, the tenant accounts have access to the forums even though the forums are only in the "shared apps" settings. The forums linked from the tenant accounts are empty but the should not even exist. Apparently "shared apps" means a shared schema. Another problem is that currently a tenant superuser has the ability to change content that is in a shared app. For example the tenant1 superuser could add/delete forums. This superuser can also see users for the whole site. Is there a way to setup django-tenants so that there is essentially a main project with sections that all users have access to but tenant users only have access to apps in the "TENANT_APPS" section of the settings.py file from inside of the tenant account (ex: tenant1.sitename.com)? -

Django-compressor has a JS cache folder that is using an absurd amount of space
I woke up this morning to alerts from sentry that my production server has completely run out of space. It took some time figuring out the cause via ncdu, and the results were that my static folder had used over 60GB of space, specifically, CACHE/js that django-compressor is using. I am not completely sure what is happening, or why there are over 500,000 js files where each file is following this format: output.<random string>.js. From my understanding, shouldn't there only be a small number of js files cached? My project doesn't even have that many scripts! It seems to me that every user is getting their own output file, instead of the same cached files being shared to everyone.

How to add a model containing a FilePathField item to an admin panel
I've set up a model which contains a FilePathField() item with the path '/img'. The img folder is located in a static folder in that app and the whole setup works perfectly when adding items through the shell interface. The problem comes in when I try to set up the admin panel to include this model where I get a FileNotFoundError when trying to open existing items or add new ones. The error is: FileNotFoundError at /admin/work_done/project/2/change/ [WinError 3] The system cannot find the path specified: '/img' To get around this I changed the path property to the absolute path with: path=f'{Path(__file__).parent.absolute()}/static/img') This makes the admin panel work but when I add items with that in place the image doesn't show up because it's looking for an image at localhost:8000/static/C%3A/.../static/img/image.png. Is there a way to make this work in admin and have the image show up? I've only found an answer to getting it working in admin but that doesn't mention the image not working in the website. The code I'm using to actually display the image is '{% static project.image %}'. I have tried changing it to '{% url project.image %}' as a long shot but unsurprisingly it didn't … -

So that's what I did: <a id ="register" href="{% url 'register_view' %}"> register now</a> and inside my urls.py of the app "login" I also wanted to call the path "register_view" with the name-attribute: urlpatterns = [ path('', login_view), path('register/', register_view, name="register_view"), ] but the problem is: it won't find the attribute "name" inside `path() and I have no idea why. Can you help me out here? Thanks in Advance!
