Calling Django Function from JS Ajax not working
I am trying to call a python function that calculates and converts some number input from a user form. I have an onclick button event to call the following JS function $.ajax({ type: "POST", url:"/calc_ha_range/", dataType: 'json', data: {'ra_deg' : ra_deg, 'dec_deg': dec_deg, 'glon_deg': glon_deg, 'glat_deg': glat_deg}, success: function(data) { jsonData = JSON.parse(data); ha_start.setAttribute('min', jsonData.min); ha_start.setAttribute('max', jsonData.max); ha_end.setAttribute('min', jsonData.min); ha_end.setAttribute('max', jsonData.max); // data.min = minimum val for HA range } }) I then have a django url mapping in the form of path('calc_ha_range/', utils.sensitivity_db.calc_hour_angle_range) which refers to the following python function def calc_hour_angle_range( request ): geo_lat = EarthLocation.from_geodetic(lon="XXXX",lat="XXXX",height=XXXX).lat.value if request.method == "POST": ra_deg, dec_deg, glon_deg, glat_deg = request.POST["ra_deg"], request.POST["dec_deg"], request.POST["glon_deg"], request.POST["glat_deg"] tan_geo_lat = math.tan( geo_lat*(math.pi/180.00) ) tan_dec = math.tan( dec_deg*(math.pi/180.00) ) cos_ha = -tan_dec * tan_geo_lat ha_rad = math.acos( cos_ha ) ha_deg = ha_rad*(180.00/math.pi) ha_h = ha_deg/15.00 output = {'min': -math.fabs(ha_h), 'max': +math.fabs(ha_h)} My issue is when the ajax call takes place in the onClick function I get an error in the console saying 404: mysite.com/calc_ha_range/ not found I have taken over this project from another amateur developer so my understanding of ajax and django is quite fragmented -

Django free usage before subscription design question?
I have a Django app using a custom user allauth for a basic user sign up. Inside my application I have the ability to generate a report. However, after the user generates a single report I want to force a subscription using stripe payment processing. For doing something like this will I need a single user type or multiple user types and what is the best way to implement a forced subscription on a basic user model already created or will I have to rip the bandaid off and redesign the user model with a counter for the report usage? -
Temporarily Storing A List of Custom Class Objects in Django
I’m using an api (Spotify) to receive search results(Playlists and their data) and displaying them on my website. I could just directly print out the results to the website in an HTML table, however I need to perform Regex to get values. I created a PlaylistObject class to create where I stored only the attributes from the search that I want to use, as well as my regexs to find an email and username. I do not store this value in the database because it’s temporary and doesn’t need to be saved for long term. The problem I am having is with Pagination. The way I have the program set up, it has to recall the Spotify API function call that’s gets the search and assigns it to my list of PlaylistObjects every single time the page reloads. Because of pagination, it reloads every time the page is changed. The pagination is working and the program functions, however I want to find a way to temporary story my list of Spotify Objects, that way I dont have to recreate it every time I change the page. I don’t want to use a database because it would get filled fast with … -

How to use a ManyToMany field in django with a through model, displaying it and saving it?
I am doing a basic system in Django for a Spa that requires me to have an inventory, massages that use different quantities of product in the inventory, and then a service which will be a combination of multiple massages. So the user of the spa, which is the staff, will be able to create a service, select which massages make that service, and that will instantly trigger the subtraction of that product from the inventory. I used a many to many relation to relate the massages and the items, with a through model to save the amount used as well. My question is, what would be the best way to display this in a form so the staff can add new massages in a way where they can choose many items and their respective quantity that the massage will use? And how can i save all of this afterwards into the DB? I'm using PostgreSQL. This is how my models look right now: class Producto(models.Model): nombre = models.CharField(max_length=200, blank=False) línea = models.CharField(max_length=200, blank=False) proveedor = models.CharField(max_length=200, blank=False) costo_mxn = models.DecimalField(blank=False, max_digits=10, decimal_places=2) unidad_de_medición_choices = [ ("g", "g"), ("mL", "mL"), ("oz", "oz"), ] unidad_de_medición = models.CharField(max_length=20, choices=unidad_de_medición_choices,null=True, blank=True) cantidad_actual = … -

dj-rest-auth - Disable sign up with social account but allow login
what I want to do is have users register using a standard registration page and then have them link their facebook account once in the application which will then allow them to sign in using the "Sign in with facebook" button.

Memory issues when sending many files in a row using Requests
In my local folder, I have around 100 css, js and svg files that I'm trying to send via REST api to a Django application. File sizes range from 50KB to 2MB. I'm using requests the following way to send the files one by one, in a loop. requests.post(url, files={"file": open('app.js', 'rb')} Some files get sent and others don't. Every time I re-try, some files that got sent the first time fail, and some that failed the first time succeed. Which file fails and which succeeds is totally random. Logs show a very strange behavior. It seems that the contents of the file that I'm sending, end up in request line and header, not request body where they should be.

How can you assign multiple string values to an attribute in Django models
class Customer(models.Model): user = models.OneToOneField(User, null=True, blank=True, on_delete=models.CASCADE, related_name="Customer", limit_choices_to={'is_staff': False}) employee = models.ForeignKey( Employee, null=True, blank=True, on_delete=models.SET_NULL) # locations = What should go here? business_name = models.CharField(max_length=200, null=True, blank=True) phone_no = models.CharField(max_length=200, null=True, blank=True) address = models.CharField(max_length=500, null=True, blank=True) website_url = models.URLField(null=True, blank=True) created_at = models.DateTimeField(auto_now_add=True) updated_at = models.DateTimeField(auto_now=True) As you can see here, I have a locations field which. This field is to store at most 5 locations the business is located in. How can I best achieve this? I have read about using a Many2Many field but this would not be desirable as the locations would have to be first created in the Admin and then added to the business. -
Using django-auditlog, how can I display the 'actor_id' for a particular model?
I have created a simple Django application to display individual articles. These articles have a number of fields that users can edit. I am using the package 'django-auditlog' to log changes to these article models. So far, I have simply followed the auditlog installation doc to setup model history tracking (as well as enabling the middleware to allow 'actor_id' to be tracked). I have also added the example code that displays the most recent changes on the individual model pages as such: <!-- History display --> <div class="table-responsive"> <table id="history" class="table table-striped table-bordered"> <thead> <tr> <th>Actor</th> <th>Field</th> <th>From</th> <th>To</th> </tr> </thead> <tbody> <!-- Human readable - change to '.changes_dict.' for proper logs --> {% for key, value in article.history.latest.changes_display_dict.items %} <tr> <td>{{ article.history.latest.author_id }}</td> <td>{{ key }}</td> <td>{{ value.0|default:"None"|striptags|safe }}</td> <td>{{ value.1|default:"None"|striptags|safe }}</td> </tr> {% empty %} <p>No history for this item has been logged yet.</p> {% endfor %} </tbody> </table> </div> As my code may suggest, I am trying to add an additional column to the history table to show who made the changes that are being displayed. Is there an easy way to do this through auditlog, or will I have to create some kind of sql query … -
How does django's `python manage.py shell` keep the command prompt open?
When you run python manage.py shell, (or shell_plus if you have the extension), the script will import some stuff for you and then open a regular python shell for you to try commands out, as opposed to running the script and immediately closing. I know that you can use the -i switch when calling a script to keep the command prompt open, for example python -i foo.py will run the contents of foo.py yet keep the shell open instead of immediately closing. I would guess that when you call django's manage.py shell it somehow uses the same feature to get the command prompt to stay open and not immediately close out. How does it work? Can I add something to any script file to make it behave the same way (without using the -i switch) ? -

Why am I unable to add data to django Model's objects
So this is a bit weird. I make a post request from the website I'm working on, I get the data on the backend but I can't access the model's field with the received data.

OpenGraph show full image size in preview
I want to show a thumbnail when sending a link. I tried it with using open graph and now it looks like that: but I want it to look like this: how can I change the size of the image in the preview. This is my code right now: <meta property="og:image" content="/media/{{ image }}"> {{ image }} is just my templatetag for the image but that works like expected so there is no need to change something there. If it's necessary I'm also able to change the service from opengraph to some other if changing the size is not possible there.
