How to alter label tag of fieldset in admin.tabularinline
I customized my add user form in my django admin, using admin.tabularinline. So whenever the admin adds a user, information about Usermodel and UserProfile model is saved at the same time. However, the label tag of the UserProfile form says 'Staff Profiles'(with 's'). And it doesn't look good because there is only one profile for one user. Any ideas how to change the "Staff Profiles" into "Staff Profile"? See the picture for refenrce: -

Bootstrap theme disappears when passing pk parameter, but uses Bootstrap4 default design
I'm using a bootstrap theme, Looper. Everything was going great on my "prescription_request_review.html" page, which contains a Bootstrap table and a Bootstrap form, until I added a pk parameter to the page. Instead of displaying my bootstrap theme as every other page does, it displays what I assume are Bootstrap4 defaults (bright blue button, plain white background, simple design.) I tried removing part or all of the {% block extrahead %} in prescription_request_review.html, but all it does is remove ALL Bootstrap components. Why would my theme change just because I'm passing a pk to the page? vhome.html Page where user can click prescription in rxtable.html, redirecting to the page I'm having the issue with: {% extends 'app/main/base.html' %} {% block extracss %} <link rel="stylesheet" type="text/css" href="static/assets/DataTables/datatables.css"/> {% endblock extracss %} {% block content %} {% include "app/veterinary/snippets/rxtable.html" %} {% endblock content %} {% block extrascripts %} <script type="text/javascript" src="static/assets/DataTables/datatables.min.js"></script> <script type="text/javascript"> $(document).ready( function () { $('#vrxTable').DataTable({ "order": [[ 6, "desc" ]], "paging": false, "info": false, "searching": false, "columnDefs": [ { "targets": 0, "orderable": false } ] }); }) </script> {% endblock extrascripts %} rxtable.html (actual table where the buttons are that lead to my problem page: <!-- list of open … -
Cannot redirect to correct URL after login using allauth get_login_redirect_url
I have a custom user model and am using django-allauth to manage the login ,sign up, logout functions. I have 5 user types and after each type login, they will be directed to separate pages. The usual LOGIN_REDIRECT_URL is not suitable for me since it can only redirect to one page no matter what type of users login. I found out that by using Custom Account Adaptor and override get_login_redirect_url()can make it work, so I implemented it. users.adaptor.py from django.conf import settings from allauth.account.adapter import DefaultAccountAdapter from django.http import HttpResponseRedirect, HttpResponse from django.shortcuts import resolve_url, redirect class MyAccountAdapter(DefaultAccountAdapter): def get_login_redirect_url(self, request): # path = super(MyAccountAdapter, self).get_login_redirect_url(request) current_user=request.user if current_user.user_type == 1: path='doc/dochome/' elif current_user.user_type == 2: path='lab/labhome/' elif current_user.user_type == 3: path='recep/recephome/' elif current_user.user_type == 4: path='patient/patienthome/' elif current_user.user_type == 5: path='admini/adminhome/' else: return HttpResponse("Your Rango account is disabled.") return path # .format(username=request.user.id) settings.py import os # Build paths inside the project like this: os.path.join(BASE_DIR, ...)

Reverse for 'communication-detail' with keyword arguments '{'pk': ''}' not found. 1 pattern(s) tried: ['communication/communication/(?P<pk>[0-9]+)/$']
I wanted to create a new app (communication) in my project that shared very similar properties to my original app (surveys). I essentially copy and pasted the same code into the new app and renamed everything. Unfortunately, now the details page of Communication is broken. The correct pk is showing up in the URL of the page and the views is being accessed correctly. However, the Django debug page is claiming that the pk that has passed through is nothing (''). When I print item.id, it all is correctly displayed. I've tried changing the view referenced in the urls.py to be a different view that I know works and it is successful. My theory is that somehow my specific view doesn't work? views.py class CommunicationView(LoginRequiredMixin, View): model = Communication fields = ('name', 'language', 'prompt_type') def get_success_url(self, **kwargs): return self.object.get_prompt_url() return reverse_lazy('communication-prompts', args = (self.object.id,)) def get_context_data(self, **kwargs): context = super().get_context_data(**kwargs) if self.request.GET.get('project'): context['project'] = Project.objects.get(id=self.request.GET.get('project')) return context def get_initial(self): initial = super().get_initial() # context = self.get_context_data(**kwargs) if self.request.GET.get('project'): initial['project'] = Project.objects.get(id=self.request.GET.get('project')) return initial.copy() class CommunicationDetail(CommunicationView, DetailView): template_name='communication/communication_detail.html' def get_context_data(self, **kwargs): self.object = self.get_object() context = super().get_context_data(**kwargs) context['project'] = self.object.project print(context) return context urls.py app_name = 'communication' urlpatterns = [ path('', … -

Extending field permission - Django

Cannot locate base.html in root directory. Suspect template loader as problem
I have a base.html file in my root directory. I have a hello_world.html file in my personal_portfolio app's template file that contains {% extends base.html %} in hello_world.html. I have the appropriate entry in the 'DIRS': settings of my personal_portfolio project. I get a template not found error for base.html. In the debug info I see reference to 'django.template.loaders.app_directories.load_template_source'. My impression is that when 'APP_DIRS': is True, this loader is responsible for automatically loading each apps template file in a list of directories to search for templates. I see no reference to ' 'django.template.loaders.filesystem.load_template_source' which I understand is responsible for adding directories in the 'DIRS': setting to the search list. This is how base.html should be located. However, it seems that no matter what I do only the django.template.loaders.app_directories.load_template_source' loader is used. I even tried including a setting for TEMPLATE_LOADERS in settings.py. What I did as a work-a-round is modify the the app_directories.py module to add the directory I am pointing to in the 'DIRS': setting. Here is the app_directories modification in E:\Python Programs\Web Projects II\rp_portfolio\venv\Lib\site-packages\django\template\loaders\app_directories.py. enter code here #************** Revised app_directories.py """ Wrapper for loading templates from "templates" directories in INSTALLED_APPS packages. from django.template.utils import get_app_template_dirs from .filesystem import … -
How to modify url for pagination with aditional get parameters
I'm realising a search list using a simple form using GET. After that, I'm trying to introduce pagination to the list of objects that has been found using that form. The problem is that, inside of the template, I'm using the attribute request.get_full_path and then, adding the attribute 'page' with the following number of the paginator; I use that method because I don't want to loose all the information that the URL contains (csrfmiddlewaretoken, and my others form's parameters). The problem comes when I click more than once on the pages links, because my url has converted in something like: 'URL-WITH-GET-PARAMETERS'&page=X&page=N. The variable called 'worker list is the list of objects returned after the search. {% if workers_list.has_previous %} <a href="{{ request.get_full_path }}&page=1"> First </a> <a href="{{ request.get_full_path }}&page={{ workers_list.previous_page_number }}"> Previous </a> {% endif %} <span class="current"> Page {{ workers_list.number }} of {{ workers_list.paginator.num_pages }}. </span> {% if workers_list.has_next %} <a href="{{ request.get_full_path }}&page={{ workers_list.next_page_number}}"> Next </a> <a href="{{ request.get_full_path }}&page={{ workers_list.paginator.num_pages }}"> Last </a> {% endif %} I expect the output of 'my-url-pah-&formparameters=results&page=N'. -
How to fix: TypeError: QuerySet.annotate() received non-expression(s): eqmunir
I am adding a like functionality in my website where users can like each others posts. I have done this successfully, however have one issue. This is checking whether the user has already liked the post, which has to be performed specifically in my HOME view. This is so I can render my home page. To encounter this issue, I perform a .annotate() on my posts when retrieving them, and see if a user has liked a post.
