Django Middleware and threading to catch the current user
I'm trying to use catch the Django user in the Middleware but without success. Using Python 3.6 and Django 1.11. from threading import local _user = local() class CurrentUserMiddleware: def __init__(self, get_response): self.get_response = get_response def __call__(self, request): _user.value = request.user return self.get_response(request) def get_current_user(): return _user.value I need to save the request.user outside the class, in the get_current_user(), but it is not working. Can someone give me a clue why I can't have the _user.value in the get_current_user() ? Thanks, -
How do I allow multiple selects for my template forms?
I have two models: a Course model which has a many-to-many field to the Student model. I made an enroll and a disenroll forms for the student, problem is, I had to change how they are rendered and so, now I cannot do multiple select. Right now a button and a checkbox appear near each student name. Problem is, if I move the button outside of the loop, it will work, but only for the last student selected, and not for all selected.. So I need to change the template in order to work with multiple select but keep the rendering behaviour. {%with crs_stud=course.student.all %} {% for student in students %} {% if student in crs_stud %} <form action="." method="POST"> {% csrf_token %} <label for="id_{{ student.id }}"> <p>{{ student.name.upper }} is already enrolled.</p></label> <input type="checkbox" id="id_{{ student_id }}" value="{{ student.id }}" name="student_ids2"> <input type="submit" value="Disenroll"> </form> {% else %} <form action="." method="POST"> {% csrf_token %} <label for="id_{{ student.id }}">{{ student.name }}</label> <input type="checkbox" id="id_{{ student_id }}" value="{{ student.id }}" name="student_ids"> <input type="submit"> </form> {% endif %} {% endfor %} {% endwith %} course = Course.objects.get(slug=slug) if request.method == 'POST': course.student.add(*request.POST.getlist('student_ids')) course.student.remove(*request.POST.getlist('student_ids2')) return redirect('classroom') -

javascript/jquery dropdown menu selection not passing GET request
In my page I have a dropdown menu, and upon selection I want to pass a GET request. This GET request should (ideally) trigger a function from my views.py file and return some data (based on the selection) from my database. However, it doesn't seem like anything actually happens upon dropdown menu selection. Here is my script that I wrote to trigger the GET request when a selection was made: <!-- AJAX Call for dropdown menu selection --> <script type="text/javascript"> var url = $('.dropdown-menu').attr('action'); $('.dropdown-menu-option').click(function(e){ e.preventDefault(); $.ajax({ type: "GET", url: url, data: { class: $('.dropdown-menu-option').val() }, success: function(result) { alert ('pass'); }, error: function(result) { alert('fail'); } }); }); </script> Here is the code for my dropdown menu in my template: <!-- Query based content for dropdown menu --> <select class="dropdown-content"> {% if current_user_properties %} {% for property in current_user_properties %} <option class="dropdown-menu-option" value="{{property.id}}">{{property.name}}</option> {% endfor %} {% else %} <option>You don't have any properties</option> {% endif %} </select> Lastly, here is the code for the function I wanna run in my views.py def property_selected(request): if request.method == 'GET': selection = request.GET.get('class', None) if selection: selected_data = MeterData.objects.filter(property=selection).order_by(date) return selected_data If anyone can help identify what I'm missing/doing wrong, that'd … -

Generate fields for a ManyToMany field with data inside the through model Django
I am here cause have no idea how to create a form for a specific case in my Django app. I'll try to explain the best I can. My site is about rentals for a kayak club. We have people that rent boats for a desired period. I want to be able to check the stock of boats before to rent them. A club can have many different boat types that it wants to rent, and a club may have some types of boats that another don't have. When I create a rental, I would like to be able to choose a number of boat for each BoatType. Let's take an exemple : I have a club A that have three BoatType it rents : C1, C2, C3. In the form, I need to have these three fields : C1 : Number Input / C2 : Number Input / C3 : Number Input I have a club B that have two BoatType in rents : K1, K2.

Godaddy domain name, DtDNS dynamicDNS, Django app, blank page
I have a weird problem at hand and I don't seem to understand the problem or find anyone who is having the same problem. I have bought a domain name on godaddy, and I want to host my personal website on my raspberry pi. I built my website using Django, and everything works well. I use Apache2 on my raspberry with mod_wsgi. Now I connected my raspberry pi to my router and registered a name on DtDNS and connected my router to it so my dynamic IP is updated automatically. When I access my website (from home or from my workplace - so I know my website is available from everywhere and not just my local network) it works as expected and I have full access to all the webpages I built. Now comes the problem. I redirected (301) my domain name on godaddy to my name on DtDNS. When I comment the part deploying my django website in /etc/apache2/sites-available/000-default.conf , and I connect to my domain name on godaddy, I see the apache page "it works !", so I know the redirection works. BUT, when I deploy my django app, and connect to my domain name on godaddy, I … -

Model can have a ForeignKey with one of the two models
I need some help with an issue that I am not able to resolve on my own. So in this model, a tenancy document can either have a ForeignKey with Building or Property. We may have a tenancy agreement on the whole building or on a single property within that building. In the former case the tenancy documents are applied to the building, and in the latter case they only apply to a property. I used content_types to add a generic foreign key but now I can’t figure out how to add autocomplete fields to contenttype and in the dropdown, I just see building and property in admin form. I want to see building names and property names. I learned about autocomplete fields in Django 2.0, it’s awesome but I don’t know how can I use something like that in this particular case or if there is a better way to do this?

Override a function call within a Django View for Testing
Something I've been unable to find despite searching high and low... Is it possible to override a variable or function call within a Django view? We have some code that calls back-end C code and writes to the database. Obviously, I would want my to prevent this call from occuring within the view. However - when I try to do a @patch... It is simply ignored and the call will occur anyway. Is it possible to over-write this within a Django view so that I can have a return value? Example code of what I've tried: @patch('clibs.api.create_dispute') def test_create_dispute(self, cfunc): f = cfunc() f.return_value = 123456 post_data = { 'dispute_amt': ['1'], 'id': ['12'], } request = self.factory.post(reverse('dispute:dispute_creation', args=[12]), data=post_data,HTTP_X_REQUESTED_WITH='XMLHttpRequest') request.user = self.user response = dispute_creation(request, id=12) -

Pillow error when using get_rendition with CMYK JPEGs
We have a custom endpoint in our Wagtail site which makes image renditions to be used in another site/admin. it uses this line rendition = the_image.get_rendition(filter + "|format-jpeg|jpegquality-80") Locally With Wagtail 1.13.1 and pillow 5.0.0 it's fine, the error only happens in production where pillow is at 2.8.2. If Wagtail manages the pillow dependency, should it be enforcing a minimum version? Is this a bug/issue or is Wagtail not suppose to manage dependencies in that way? I can just add a pillow>=5.0.0 in my production requirements file to fix it, so maybe that's fine?

Django security risk url parameters
I am trying to find a way to prevent users changing url parameters and messing around with the system. I know you can restrict users to only have access to the right content, but still if the url is www.site.com/something/10 And I change 10 to 9 in the address bar, i can access something the work flow is not designed to give access to. I can restrict the person not to view 9, but it still provide the opportunity to mess around with something, I might have overlooked. By using POST method and hiding the parameters it will cause problems as django is not designed to handle many forms in one view. Is there a way to let django rather display www.site.com/something/<Encrypted> or <Not recognisable so I can mess around> There must be some way of limiting users only to access, whatever the links provide on the current page, instead of a clever user trying to cause harm. -
Make 'Enter' key default to a certain button in a Django crispy form?
I have a form that subclasses PhoneNumberForm from the django-two-factor-auth-library. It renders a text box in which to enter phone number, and a Back button and Next button beneath it. The issue is that when the form is filled out and the user hits the 'Enter' key on their keyboard, the Back button is triggered. I have tried swapping the two buttons, which gives me the behavior I want, but not the correct layout. But I do see that whichever button is defined first in FormActions gets selected on hitting Enter. I have also tried adding an 'autofocus' field to my Next button, but that only focuses on the button when the page loads, not after I've switched focus to the text box and typed in a number. I would like to maintain the order I currently have (Back button on the left, Next on the right), but have the Enter key trigger the Next button. How do I do this? from crispy_forms.helper import FormHelper from crispy_forms import layout as crispy from crispy_forms import bootstrap as twbscrispy def __init__(self, **kwargs): super(PhoneNumberForm, self).__init__(**kwargs) self.helper = FormHelper() self.helper.form_class = 'form form-horizontal' self.helper.label_class = 'col-sm-3 col-md-4 col-lg-2' self.helper.field_class = 'col-sm-9 col-md-8 col-lg-6' self.helper.layout …
