Using cypress with django in Gitlab CI
I am developing an application using Django and I use Cypress for front-end testing. The setup works locally, but I would like to set-up the testing on gitlab-ci. I have managed to make Gitlab run Cypress tests (while the application runs on production server). What I'd like to achieve (and I am struggling to) is to have Gitlab CI running Django application (probably even with nginx/gunicorn, mimicking the production environment; but embedded dev. server would suffice, too). Is it even possible? To run the server and have Cypress running in the one go? I've seen some examples using docker-compose on Gitlab-CI for nodejs applications - but I'd like to avoid it as setting it all together correctly (so that it uses cache etc.) seems to be super troublesome task. -
Celery class based task is ran synchronously instead of asynchronously

Python3 Django Webapp HTML Test Button to print debug data
I am writing a Django web app with python 3 and I would like to add an html button that when clicked prints debug data while I'm testing.

Crop an image from x and y position using sorl_thumbnail
Python 3 and Django 1.11.15 Hi, I'm using a plugin which returns an x and y position from an image besides usual image dimensions (width and height). I'd like to crop this image with sorl_thumbnail in Python using x and y position (like image cover on Facebook). I think there is a function, maybe like cropbox(), but I don't understand how it works. Please someone can help me, giving me an example of using this function or another solution to crop an image with these data. Thanks to all. -
Django class field in if statement
I currently have two different types of user 'Lecturer' and 'Student'. In the html I am trying to create an if statement that only applies if the user is equal to one or the other.

Several labels in for loop
I'm pretty new in programming and I did the Django tutorial 'Writing your first Django app'. Now I want to make some changes to this app and I do not really know how to do it.

Django Sharing Large File Repository Between Development and Production
I'm trying to develop a Django application that will eventually serve a large media file repository (10's to 100's of GB) that would ultimately be stored on B2 or S3 instead of locally on the server. For application related static content, I think I understand that you will have a /static/ in your application tree, and a /static/ in your web server tree. When you run python manage.py collectstatic the files are compared, and the web server file tree is updated based on the application file tree. Since these would ultimately be uploaded by a user, should I instead be thinking of the MEDIA_ROOTand MEDIA_URL settings? These would then be staging areas prior to preparation and upload to B2 or S3. I've checked these out: Identical and simple way of serving static files in development and production - is it possible? Django: Deploying static files in production environment serving django media (user uploaded) files in production Serve media files with a static service. Dotcloud and I feel like they are probably starting down the right path, but there is minimal discussion so I don't know the alternatives. Are there other approaches I should consider? -
Unable to pass model to context
I'm trying to pass a single model, and a list of models with the same "document_title" to my ModelDetailView template. The code for the views.py section is class DocumentDetailView(generic.DetailView): model = Document def get_context_data(self, **kwargs): context = super().get_context_data(**kwargs) context["doc_list"] = Document.objects.filter(model.document_title).order_by('revision_number') return context I have tried passing the model into the get_context_data method, but that only produces other errors. I'm not sure if I'm going about this the correct way, but any ideas would greatly help. -

Accesing list in request.get
I'm having difficulties checking on the request.GET parameters in my Django template. django.template.context_processors.request is enabled so I can access request.GET. With the following GET parameters in my URL: ?floor=1&floor=2&building=1, I'm trying to do something like the below: {% if 1 in request.GET.floor %}IN{% else %}OUT{% endif %} I would expect this to return IN. However, OUT is displayed. When diving in more detail: {{ request.GET }} {{ request.GET.floor }} {{ request.GET.urlencode }} Following is returned: <QueryDict: {'building': ['1'], 'floor': [1, 2]}> 2 building=1&floor=1&floor=2 So it looks like my list of [1, 2] for 'floor' is reduced to the last element ('2'). What's the best way to check on the full list? -

How to load a django contrib app without modifying directly the templates of the project
I have built a django app, which when enabled (from the settings.py), can be accessed by the main menu of the project. In order to check if the app is enabled, I use this snippet in one of the templates: {% if 'my_project.contrib.edit_app' in INSTALLED_APPS %} <a class="btn btn-danger btn-block btn-xs" href="{% url "display_data" resource.service_typename %}">{% trans "Edit App" %}</a> {% elif 'my_project.contrib.edit_data' not in INSTALLED_APPS %} <a class="btn btn-default btn-block btn-xs" href="{% url "new_app" %}?layer={{resource.service_typename}}&storeType={{resource.storeType}}">{% trans "New App" %}</a> {% endif %} Apparently is not a good practice to "leak" into the core code, code of contrib apps.

How do you see what an http request contains
I'm using a django framework for my assignment. I need to view what an http request object contains. print(request) is obviously not working. If i can see the object like in a json structure it would've been a huge help to understand what it would look like and what are the values it contains.
