Django - how to pass model data with for loop and detailview
I couldn't pass model data to detail.html with for loop. ListView can pass datas with for loop but DetailView doesn't let me. I can access datas with object.name etc. but I cant access with for loop. my index.html <tbody> {% for total_amount in receipt_list %} <tr class="active"> <td>{{ total_amount.id }}</td> <td>{{ total_amount.amount }}</td> <td>{{ total_amount.vat }}</td> <td>{{ total_amount.total_amount }}</td> <td><a href="{% url 'detail' total_amount.id %}">Click for the details...</td> </tr> {% endfor %} </tbody> my detail.html <tbody> {% for object in receiptitem_list %} <tr class="active"> <td>{{ object.id }}</td> <td>{{ object.receipt.id }}</td> <td>{{ object.product.id }}</td> <td>{{ object.amount }}</td> <td>{{ object.vat }}</td> <td>{{ object.vat_rate }}</td> <td>{{ object.sub_total }}</td> <td>{{ object.name }}</td> </tr> {% endfor %} </tbody> my views.py class IndexView(ListView): template_name = "index.html" model = Receipt class ReceiptItemView(DetailView): template_name = "detail.html" model = ReceiptItem and my models class Receipt(models.Model): amount = models.DecimalField(max_digits=5, decimal_places=2, blank=True, null=True) vat = models.DecimalField(max_digits=5, decimal_places=2, blank=True, null=True) total_amount = models.DecimalField(max_digits=5, decimal_places=2 , blank=True, null=True) def __str__(self): return str(self.total_amount) def save(self, *args, **kwargs): receipt_items = self.receiptitem_set.all() self.amount = 0 self.vat = 0 self.total_amount = 0 for receipt_item in receipt_items: self.amount += receipt_item.amount self.vat += receipt_item.vat self.total_amount += receipt_item.amount + receipt_item.vat return super(Receipt, self).save(*args, **kwargs) class ReceiptItem(models.Model): receipt = models.ForeignKey('Receipt', on_delete=models.CASCADE … -

Django/Certbot - invalid response from domain/.well-known
I'm trying to set up https on our web page which runs on Django 1.8. I'm very new in this area so I use Certbot. I followed the instructions until ./path/to/certbot-auto certonly. How would you like to authenticate with the ACME CA? 1: Place files in webroot directory (webroot) 2: Spin up a temporary webserver (standalone) I've chosen 1. Then it wants my domain and the next step is: Select the webroot for salix.sk: >>> /home/django/salix which returns error Waiting for verification... Cleaning up challenges Failed authorization procedure. salix.sk (http-01): urn:acme:error:unauthorized :: The client lacks sufficient authorization :: Invalid response from http://salix.sk/.well-known/acme-challenge/some_code: " Page not" IMPORTANT NOTES: - The following errors were reported by the server: Domain: salix.sk Type: unauthorized Detail: Invalid response from http://salix.sk/.well-known/acme-challenge/some_code: " Page not" To fix these errors, please make sure that your domain name was entered correctly and the DNS A record(s) for that domain contain(s) the right IP address. I think that I should somehow set the path in my project but can't figure out how. It created a folder .well-known inside the root of my project without any visible files inside. Do you know what to do? -
Replace Django Templates with ReactJs while Django serves as the API
I am trying to figure out the ideal approach to replace Django templates with ReactJS. When people say - "Let ReactJS entirely replace your Django Templates and let Django be used only as an API", they dont really mean replacing Django Templates (and the way they are served) entirely, right? I mean my assumption is that the html pages will still be "served" through Django (as in, urls.py will still be used and point to an html template), and then in the template html, I can define a DOM node (div etc.) which React could use to populate its stuff in, yeah? -

Webpack: "Uncaught SyntaxError: Unexpected token <" in Django
My application runs fine in development, but whenever I deploy it to production I am provided with the error: "Uncaught SyntaxError: Unexpected token <". Whenever I inspect the source of the error, it is due to the webpack bundle loading index.html instead of the anticipated javascript /assets/js/index.js. I deduce that this is Webpack ignoring every request outside of index.html, but nowhere in any configurations do I have it pointing at it as default. I'd like to know how to remedy this issue and have it render what's configured as the entry point. Thanks in advance. webpack.config.js //require our dependencies var path = require('path') var webpack = require('webpack') var BundleTracker = require('webpack-bundle-tracker') module.exports = { //the base directory (absolute path) for resolving the entry option context: __dirname, //the entry point we created earlier.

Django - safe to store debugging data in request.META
As we know, if there is an error with your django application and you have debug=True, then you will see something like Although I am not sure, I assume that if debug=False, we would still have access to this same thing except django would email this html file to us instead. Following this assumption (someone please confirm), I have been tasked with adding another section to this exception template (USER, GET, POST, FILES, ETC [NEW CUSTOM SECTION HERE]). However, since I dont know how to do that, I thought an easier way would just to set a bunch of custom key values into request.META Would it be safe to do so? Like say an API secret key or something? So when something goes wrong, I would see it in the META of the formatted log? -

Creating New Model Form Fields in Django Admin
I have a product model that has a manytomany relationship to a locations model. I am creating an app for my clients business that has hundreds of products and services, but each product/service have different prices base on the delivery location and can deliver to multiple locations. Right now my client delivers to 4 locations. Solution #1 Hard code all 4 locations into the product model - this works, but is not preferred since they want to expand and hard coding more locations is just gross.. Solution #2 (current solution - code listed below) Create a manytomany relationship to locations - this works, but is getting way out of hand having location options of varying charges an rates for - multiplied by every product.... Solution #3 - This is the help I need, if a solution exists. I would like to build a hybrid of sort of the above two options. Id like to keep the manytomany with the location model so its easy to add locations as they grow, but once added, I would like to have an empty 'price' object that they can fill-in when adding or updating a product, yet remain assigned to that product only.

Using a dynamic value in the src= attribute of an image in the DJango static folder
I am trying to put {{color}}, which is a context dictionary key in a django file within my html but am having trouble getting {{color}} within the second img's source address to be recognized as a variable.... if that is even possible. My first img tag works fine. The second one receives the variable that I pass into the url (for example /blue as the color) within the alt= as the proper color or whatever color I pass. But it has trouble with my characters used when trying within the {%here%} ! <div id="wrapper"> <img id="logo" src="{% static 'disappear_maker/images/logo.png' %}" alt="Teenage Mutant Ninja Turtles Logo"> <img id="main_pic" src="{% static 'disappear_maker/images/{{color}}.jpg' %}" alt="{{color}} of the ninja turtle's character"> </div> I hope I am explaining this well. If not, my apologies. I basically have an images static folder with images named after colors (red.jpg, blue.jpg, etc) and want them to change depending on the manually typed in url extension that is passed to the browser. Thanks!! -
Django: How to calculate a context value AFTER rendering template?
The documentation for the render() method says that if a value in the context dictionary is callable, the view will call it just before rendering the template. The problem is I have a context value that takes a LONG time to calculate and the next page won't be rendered until that is done. I would like to render the next page immediately (without the value), but show a progress bar. A lame illustration I'm sure there are plenty of ways to do this with AJAX or other solutions, but I would like to do this value calculation with pure Django/python. Is there a way to calculate a value after rendering a page? (I'm not looking for a progress bar solution) -
django - Get user id from token and add it to database model
I'm working on a project using Django Rest Framework, I use token authentication using rest-auth library. A part of the project is to assign a home (from an pre-defined set of homes database) to users. I need the users to send a POST request with the home id, and then the home is assigned to this user in the database. Here is the serializer: class HomeUserSerializer(serializers.ModelSerializer): user_id=serializers.HiddenField(default=0) class Meta: model=models.Home_Users_Link fields=('home_id','user_id',) And the database model: class Home_Users_Link(models.Model): class Meta: unique_together = ("user_id", "home_id") user_id=models.ForeignKey(UserProfile,editable=True) home_id=models.ForeignKey(Saved_Homes) Noting that I have overridden the User model with the UserProfile model. I also learnt that it would be performed using request.user to get the user id, but I still can't implement the right function to add it to the database when the POST request is received
