how to django link url to decoupled react app
I have built my app with django as the backend and react as the frontend. I want to keep the two decoupled. However, I have an use case where I want to link from django to my react app. The frontend and backend will be hosted on different domains. While sending a password reset email, I need to link to a react page. The url is localhost:3000/reset/{code_here}/ I need to include this URL in an email (from the backend). I am not sure of what the best way to do this is. Should I hardcode the URL into my emails? Or is there any better way to achieve this? -

Is it a bad practice not to use django forms?
I have watched a lot of django tutorials where some use the plain html form and some use django forms and model forms. Personally, I like using the plain html form because of the ease of customization. Other than validation, I don't really see any other advantages to using django forms. So, i just wanted to ask if it is a bad practice to use html forms rather than django forms? -

What are the ways to make it possible to change contents of homepage through django admin?
I want to make it possible to easily modify the contents of my django site's homepage(and other pages too) through admin page directly. If I had multiple records of each instance I would definitely create a database model for it, which can then easily be modified through admin panel. But for things like the banner image, site description etc. which only have a single instance, am I supposed to have a database model with a single row or is there some better implementation for it? -

Django admin can't access to specific items
I'm working in Django with a model (Check) with foreign key. client_id = models.ForeignKey(Client, on_delete=models.CASCADE) Everything works fine with a regular admin register, but when I use class ChecksAdminSite, it crashes.

Django form missing none required field
I have a django admin form. The model contains a single field, called calculated. The calculated value is detemined by querying the database and performing some complex logic depending on the selection of some other field the user selects from a select box called pickme. So to make it much easier for the user, when they wish to alter an instance of the model, they select a pickme, and the system automatically calculates the required calculated field. The following code works for editing existing entries, however when I add a new entry, when I click save in the django admin interface it fails with ValueError: 'FooForm' has no field named 'calculated'. The error is raised within the Form._post_clean() method. I suspect it is because the form is not posting the value of calculated so it thinks its not a field. Looking at djangos code python3.8/site-packages/django/forms/forms.py, within _post_clean(): There seems to be a block that creates a DB instance: try: self.instance = construct_instance(self, self.instance, opts.fields, opts.exclude) except ValidationError as e: self._update_errors(e) And then a block that cleans the instance, this is where it fails: try: self.instance.full_clean(exclude=exclude, validate_unique=False) except ValidationError as e: self._update_errors(e) I could try override _post_clean but it seems extremely … -
How do I inject an HTML string into executable html with Javascript?

In my template I create a to inject this string into actual executable html rather than text, which is where my error is occuring. It seems either there is something wrong with my injection code, something wrong with my use of Jinja to import the html string, or that this is the wrong way of doing things. Here is my current code: HTML (Javascript) <script> var htmlWrapper = document.querySelector('#graph_input'); var htmlstring = {{figure}}; htmlWrapper.innerHTML = htmlstring; </script> Views def home(request, symbol): file = open('saved_model_weights', 'r') model_json = file.read() loaded_model = model_from_json(model_json) loaded_model.load_weights('h5_file') predictions = loaded_model.predict(test) fig = Figure() ax = fig.subplots() ax.plot(predictions, linewidth=0.7) ax.plot(close, linewidth=0.7) ax.set_title(symbol) figure = mpld3.fig_to_html(fig) return render(request, 'mysite/home.html', {'figure': figure}) ^ figure is the html string I want to execute in my template, which is generated by mpld3.fig_to_html(), a matplotlib library to translate graphs into. -

Heroku redis deployed backend does not cache data
First time deploying app. I'm trying to run my backend on Heroku url example:(this_is_my_app_name.herokuapp.com). I have my database deployed at AWS and connected to my backend. I've tested locally and everything seems to work. But now I have a problem when I'm trying to access my backend admin panel on deployed backend I can't access it with my login information (I can access by creating superuser but theres no data from database). I think it's redis problem and can't configure my redis right.

how to store uploaded files for a web application while using AWS ECS FARGATE
I am very new to the concept of AWS EFS. As i am currently building a web application using Django with ECS - AWS Fargate backend and javascript with react front end, which is deployed to s3. About the backend, I am wondering what would be the best way for a user to: 1/ store/upload the images related to their profile? 2/ assuming the user also own a product in the app and each product has images, how to store these images as well... Would AWS S3 or AWS EFS be the most appropriate way to store 1 and 2 above? Thanks for the feedback
