How to get the instance of current plugin object in class-based view
I am developing a plugin for django-cms. Right now, I have a class BaseMyPlugin extending CMSPlugin class and I need to get an attribute base_attr from that class in class-based detail view (MyDetailView) context. What should I import (for modules) or override (for functions) for my view? The attribute I want to get is set in runtime so I have to get the instance. It is reachable in the template context because there is an global instance of plugin. But in the view context, I can not get such an instance. I have tried the following: Import BaseMyPlugin class in the view context. Failed because it was not the instance. Override render_to_response/get_context_data/get_object methods in MyDetailView class. Failed because the parameters of these methods didn't contain the base_attr attribute. Code for my view: class MyDetailView(DetailView): ``` I want to get the BaseMyPlugin.base_attr in this view ``` view_attr='to be set accouding to BaseMyPlugin.base_attr' Code for my CMSPlugin class: class BaseMyPlugin(CMSPlugin): # target attribute base_attr='some value set in runtime' I need to get the base_attr anyway to set view_attr in view in runtime.

How to fix object representaions in django admin page on `LogEntry` model. django 2.2
I've added a code in my view to log every add action in my add_new_staff page. However, everytime I add a user on that page, the columns object_id and object_repr in LogEntry model in admin page gets this weird data representations(objects encircled with black pen): The objects encircled with red pen are the users I added on the django admin page, and it didn't get weird representations. These are the code I added in my add_staff_view : log = LogEntry.objects.log_action( user_id=request.user.id, content_type_id=ContentType.objects.get_for_model(User).pk, object_id=User.id, # or any field you wish to represent here object_repr=repr(User.username), action_flag=ADDITION, # assuming it's a new object change_message=message,) # a new user has been added log.save() How can I fix this problem? Any help would be really appreciated. -
Django template re-rendering
So I have a django DetailView that I can easily render by getting all the data that I need from get_context_data in my class based view. But the problem is that each time to render this template I would need to choose a date in this template, get the date somehow and then re-render that same template from the date picked. I've been googling how to make this happen, there are something I could maybe do with AJAX, but maybe there is something easier to try, because I have little to no experience with AJAX/JS stuff class PlaceDetailView(LoginRequiredMixin, PermissionCheckMixin, PlaceViewMixin, DetailView): template_name = "places/place_detail.html" def get_context_data(self, **kwargs): context = super(PlaceDetailView, self).get_context_data(**kwargs) place = context.get("object") contract = Contract.objects.filter(pk=place.id).first() context["renter"] = User.objects.filter(pk=contract.renter_id).first() now = timezone.now() meters = MeterInstallation.objects.filter(places=place.id) context["active_meters"] = meters.filter(active_until__gte=now) context["old_meters"] = meters.filter(active_until__lt=now) context["services"] = ServiceTask.objects.filter(place=place) # Need to add more context values from more models, but the date has to be given, how? return context place_detail_view = PlaceDetailView.as_view() <div class="tab-pane fade show active" id="values" role="tabpanel" aria-labelledby="values-tab"> {% if values %} <div class="table-responsive-sm"> <table class="table small"> <thead> <tr> <th scope="col">#</th> <th scope="col">Values</th> </tr> </thead> <tbody> {% for value in values %} <tr> <th scope="row">{{ forloop.counter }}</th> <!-- todo add needed values … -
Use custom js file for FilteredSelectMultiple widget
I am struggling while trying to include FilteredSelectMultiple widget to user form. I finally managed to add it make make it show on regular user form (detailed way I did it in my previous question), but now I need to customize it a bit (resize, provide translations to buttons, tool-tips and similar things). I managed to find a similar question in this forum and determined that I need to edit SelectFilter2.js file (I do not know js, but managed to change required label/button text in it). Also will edited styles.css adjust widget size. And will put these files in my_app/static/ directory. But I cannot figure out - how to make django look at these custom files instead of original ones?

Copying .csv file located on Heroku server to local drive
I have a Python/Django web application deployed to Heroku that writes information to a .csv file. Once the file has been written I want to pull it down from the Heroku server to the users local drive. I don't need to persist the file anywhere and so I am avoiding using S3 or storing in the database. I have used the Heroku "ps:copy" command which works but surely this would mean the user would need the Heroku CLI installed on their machine for this to work? Is there any other way? Thanks -

How to use multiple forms in Django 2.1?
Sorry for asking similar questions, but other similar questions/answers do not help me with Django 2. Question: I have two actions, one is to show some data as a table. In the second form I edit this data and will save it as a table using django in the database. Here is some code: in simple_upload.html <form method="post" enctype="multipart/form-data"> {% csrf_token %} <input type="file" name="myfile" value="formOne"> <button class="btn btn-primary" type="submit">Upload</button> </form> The second form: <form method="post" enctype="multipart/form-data"> {% csrf_token %} <input type="hidden" name="mytable" value="formTwo"> <table class="table" border="1" id="tbl_posts"> <thead> <tr> ... </tbody> </table> <input type="submit" value="Submit"> </form> in views.py def simple_upload(request): if request.method == 'POST': ... if request.is_ajax(): return render(request, 'project/simple_upload.html', {'section': 'project', 'lines': zipped}) return render(request, 'project/list.html', {'section': 'project', 'lines': zipped}) return render(request, 'project/simple_upload.html') in urls.py: urlpatterns = [ ... path('', views.simple_upload, name='list'), ... ] in list.html: ... {% include "project/simple_upload.html" %} ... In this case only the first form works, the second one fails. Question 1: Can I do "if request.method == 'POST' and 'formOne' in request.POST:", I try but it does not react at all.

Settting up logger to send emails to address different than admins
In the settings file I have a logger set up to send any errors to ADMINS which is the default behavior.

I have my own logging function which writes to a file. Basically I want to send an email to that other address instead. How can I do this?
