Adding content_type to render_to_response in Django's views.py causing 'Server Error (500)'
In django 1.11, in views.py I am using the render_to_response function as follows: return render_to_response(domainObject.template_path, context_dict, context) This works fine. Now I am trying to specify the content_type for this response as 'txt/html'. So I switch to content_type = 'txt/html' return render_to_response(domainObject.template_path, context_dict, context, content_type) But with this setup the server returns a Server Error (500) Following the documentation at https://docs.djangoproject.com/en/1.8/topics/http/shortcuts/#render-to-response I think I am providing the variables in the right order... Here is the full 'def' block for reference: def myview(request): context = RequestContext(request) if request.homepage: migrationObject = calltomigration() else: integrationObject = Integration.objects.filter(subdomain_slug=request.subdomain).get() except ObjectDoesNotExist: logger.warning(ObjectDoesNotExist) raise Http404 sectionContent = None if not request.homepage: sectionContent = getLeafpageSectionContent(referenceObject) context_dict = { 'reference': referenceObject, 'sectionContent': sectionContent, 'is_homepage': request.homepage } # content_type = 'txt/html' return render_to_response(domainObject.template_path, context_dict, context) -
How can I refresh only the child page that contains a form in Django environment
I've been working on a Django form. The form is in the poc_add.html site. The index.html side contains the <div id="output"></div> that is being filled out with the poc_add.html content. In other words the poc_add.html site is a part of the index.html site. Here is the code of the form: <form class="form"> {% csrf_token %} <fieldset> <label class="mb-0" for="cmbLocation">Location</label> <div style="padding-bottom: 15px;" class="row mb-1"> <div class="col-lg-12"> <select class="form-control" id="cmbLocation"> {% for location in locations %} <option value="{{ location.0 }}">{{ location.1 }}</option> {% endfor %} </select> </div> </div> <label class="mb-0" for="cmbCertification">Certification</label> <div style="padding-bottom: 15px;" class="row mb-1"> <div class="col-lg-12"> <select class="form-control" id="cmbCertification"> <option>Lead Prep</option> <option>Greeter</option> <option>Lead Trainer</option> </select> </div> </div> ...... ...... <div id="divAddNewPOC" style="padding-bottom: 10px;padding-left: 2px;"> <button class="btn btn-primary custom-btn" id="btnNewPOC" data-dismiss="modal">Save</button> </div> </fieldset> </form> Here is some JavaScript codes of the poc.js file that is included in the poc_add.html page. $("#btnNewPOC").click(function(){ var selectedLocationVal = $("#cmbLocation").val(); var selectedCertificationVal = $("#cmbCertification").val(); console.log("Location val: " + selectedLocationVal); console.log("Current Objective val: " + selectedCurrentObjVal); console.log("Correct Uniform val: " + selectedCorrectUniformVal); $.post("poc_form_submit",{'location': selectedLocationVal, 'certification': selectedCertificationVal, ...... ...... ...... }, function(data) { ..... ..... ..... }, "html"); }); Here is some part of the urls.py file urlpatterns = [ path('', views.login, name='login'), path('index', views.index, name='index'), .... … -

mentioning or tagging users or any models in django
Let's say I have a django project of a social network and this site has many users. All the users come from django.contrib.auth.models.User class. Now one user let's say writes a blog and in it, mentions another user with '@' similar to of twitter. So exactly how to do this? What kind of approach should be taken? And coming away from just user model, rather how to do this with any custom model also? Like if I have a Blog model and each blog has a title, how to mention with that title? And most importantly this mentioning should be an automatic thing. Like If one user's name is "PhantomWarrior", then if one writes "@Phant" and he is still writing, it should automatically predict the username "PhantomWarrior" and give the user option to select that for mentioning. Similarly how to do this with the title of a blog? I found this post: how to mention/tag users with '@' on a django developed project in stackoverflow talking about this thing but the answer kind of did not satisfy what I am wanting. So how to do this? Any help will be much appreciated. -

Django NoReverseMatch - is not a registered namespace
I am following this tutorial to integrate PayPal into my website. It works perfectly and I am really happy with the concepts I have learned thus far. However, I would also like to integrate a subscription service which is explained in the second tutorial, but I am stuck at this part. First, there is a typo I believe in the 'subscription' function at this line: return render(request, 'ecommerce_app/subscription_form.html', locals() <-- missing closing ')' Second, I get this error: NoReverseMatch at /process_subscription/ 'payment' is not a registered namespace When I navigate to http://localhost:8000/subscribe/ and fire the subscribe button. If anyone is able to figure out what I am missing here or can get this issue fixed for me is highly appreciated :) p.s. I am just a Django beginner. -

Web-based application to visualize results of data analysis
So, im doing some data analysis using python and PyTorch and i want to develop an app to show the results that is able to run on all kind of devices, so probably something web-based.

What should I use for the front-end of my database project?
I just finished writing a program in Python that will automatically watch a folder for some files and when it sees certain files it is adding their data to a MySQL server. I am happy with the way that is working. It uses Python, and Pandas. I am now looking for a way to display, edit, change, add, remove, etc. data from this database but on the front end. I want to set something up that is user friendly to someone who doesn't know how to program, and doesn't know MySQL commands. It doesn't have to be too advanced, but I want to be able to customize and change it to fit my needs. I will be running it locally, through the same MAMP server that is running the MySQL server. I was looking into Django to do this, but I wanted to get some input before taking off. I liked the idea of using Django, because I did the project in Python. But I am not completely attached to sticking with Python, if there is something else that will clearly work great. Any help is appreciated. Thanks! -

Django Channels setting custom channel_name
I'm using Django channels and I'm able to properly connect and send message with builtin channel_name provided. I'm wondering if there is a way to change and register a custom channel_name within web socket connection. I tried changing it but channel_layer alredy stored builtin channel_name and I'm unable to send a message. This is a provided test class class TestWebSocket(AsyncWebsocketConsumer): async def connect(self): self.channel_name = "custom.channelname.UNIQUE" await self.accept() async def test_message(self, event): await self.send(text_data=json.dumps({ 'message': event['message'] })) Here how I send a message: async_to_sync(channel_layer.send)('custom.channelname.UNIQUE', {'type': 'test.message', 'message': 'dfdsdsf'}) I read documentation and it stores channel_name inside db, but each time I perform a connection, that name will change. I want to avoid flooding db with update calls. So this is why I'm trying to force my own channel names. There is a way to change it or is oly waste of time? -

How to add buttons in the Django admin interface to update a model field?

How to query fields from two related modelforms in a template
What I would like to do is show a table listing all authors, and for each author list their respective books.

How can I push Django code using dj-database-url, psycopg2 to Heroku?
I am currently building a web project in Django and working on getting the site ready for deployment. I initially deployed the site on Heroku using Sqlite3, with my database code in settings as follows: DATABASES = { 'default': { 'ENGINE': 'django.db.backends.sqlite3', 'NAME': os.path.join(BASE_DIR, 'db.sqlite3'), } } However, due to Heroku's ephemeral file system I realized I needed to switch to Postgres. After following a few different guides I arrived at the following changes to my settings. I first deleted the "DATABASES" as mentioned above and replaced it with the following: import dj_database_url, psycopg2 DATABASES = { 'default': { 'ENGINE': 'django.db.backends.postgresql_psycopg2', 'NAME': *************, 'USER': **************, 'PASSWORD': ************************************, 'HOST': *********************, 'PORT': '5432', } } db_from_env = dj_database_url.config(conn_max_age=500) DATABASES['default'].update(db_from_env) When I make these changes everything works perfectly on the local Django development server (127.0.0.1:8000), but once I push the changes through Git and to Heroku I try opening my site on Heroku and get "Application Error" and a suggestion to check my logs. Which report "ModuleNotFoundError: No module named dj_database_url" and similarly any outside library I try to upload to Heroku appears to have this issue. How can I fix this issue and move my site into production? Any help would be … -
Stripe Subscription Events Django

Here's an example, a customer signs up for a subscription and pays in full, the subscription clears stripe and becomes active. One month later, the customers credit card is charged again, but is denied. I read here that Stripe sends two events when this occurs: charge.failed event and an invoice.payment_failed. How would I listen for these events? -
