Django make migrations contanstly creates AlterField for many-to-many field
I have a very annoying situation with my model I renamed a Model used as ManyToMany table # The business models contains this field admins = models.ManyToManyField("users.User", through=BusinessMember) # this is the many to many model used in in Business class BusinessMember(models.Model): user = models.ForeignKey( "users.User", related_name="memberships", null=False, on_delete=models.CASCADE ) business = models.ForeignKey( "business.Business", related_name="members", null=False, on_delete=models.CASCADE ) class Meta: db_table = "myproject__business_member" This model once was called "BusinessUser" and I had to rename it. I created the following migrations to rename the Model # Rename and alter model table 0011_rename_business_user_model.py class Migration(migrations.Migration): dependencies = [ ("business", "0010_add_business_field"), ] operations = [ migrations.RenameModel("businessuser", "businessmember"), migrations.AlterModelTable( name="businessmember", table="myproject__business_member", ), ] # Another migration to update the sequence class Migration(migrations.Migration): dependencies = [ ("business", "0011_rename_business_user_model"), ] operations = [ migrations.RunSQL( "alter sequence myproject_business_user_id_seq rename to myproject__business_member_id_seq;" ), ] After this change, the makemigrations constantly create a migration with this AlterField migrations.AlterField( model_name='business', name='admins', field=models.ManyToManyField(through='business.BusinessMember', to=settings.AUTH_USER_MODEL), ), It doesn't matter how many times I migrated this AlterField, Django creates another migration every time. Do you have any idea what I did wrong? -
How to pass data to a template without passing it through the view?
I have a base.html file where on the sidebar it loops through all the spaces inside of my Spaces model and displays them as links. I am wondering instead of passing these spaces through each view is there a way to just have them in the base template? I tried looking it up an came across template tags but I don't think those are what I am looking for. Base.html <div class="sidenav"> <h2>Spaces:</h2> {% for space in spaces %} <a href="/{{space}}">{{space}}</a> {% endfor %} </div> Right now I am passing 'spaces' through my views but I don't want to have to do that in each view i create. Any help would be appreciated! -
How to resolve code duplication in View for model instances filtering
I trying to figure out how to resolve probably a very simple issue, but I would like to do it in an appropriate and Django consistent way. Let's assume that we have an example model: class ExmapleModel(Model): vote_up = models.IntegerField(default=0) vote_down = models.IntegerField(default=0) def get_voting_count(self): return self.vote_up - self.vote_down Ok and now I would like to create separate views on one template for ExmapleModel which will have for instance voting count higher than 500 and for all instances. Of course, I could create something like: class ModelListView(ListView): model = ExmapleModel template_name = 'ExmapleModel_list.html' and the second one: class ModelListView(ListView): model = ExmapleModel template_name = 'ExmapleModel_list.html' queryset = ExmapleModel.objects.filter(get_voting_count()>300) Assuming all the above, I would like to prevent repeating a lot of code for the above example, I have no idea how to user a get_voting_count() method for filtering and combining all of those things for the working package. If you have any ideas on how to combine it please help me. On other hand should I use this logic within Model? -
How can I use the same mock database both while testing normal django views and api views?
I have a following problem: I run tests using TestCase and create some data for my database. However, before rendering the template the view uses some API calls and receives information from the real database instead of the mock one. Is there a way to solve this problem? Or maybe I should test the view and the API view separately? Maybe I should create APITestCase? Any help will be appreciated. -
How to get "Historical" Queryset for the dataset using Django ORM?
I have CurrencyHistory model along with the database table which is populated on every Currency model update for the historical data. class CurrencyHistory(models.Model): id = models.AutoField(primary_key=True) change_rate_date = models.DateTimeField(_("Change Rate Date"), auto_now=False, auto_now_add=True, db_column='change_rate_date') code = models.ForeignKey("core.Currency", verbose_name=_("Code"), on_delete=models.CASCADE, related_name='history', db_column='code') to_usd_rate = models.DecimalField(_("To USD Rate"), max_digits=20, decimal_places=6, null=True, db_column='to_usd_rate') Database structure looks like id | change_rate_date | code | to_usd_rate 1 | 2021-01-01 | EUR | 0.123456 2 | 2021-01-01 | CAD | 0.987654 3 | 2021-01-02 | EUR | 0.123459 4 | 2021-01-02 | CAD | 0.987651 I need to fetch data using Djnago ORM to have a dictionary to display single row per date with the every currency as columns, like this Date EUR CAD 2021-01-01 0.123456 0.987654 2021-01-02 0.123459 0.987651 But I have no idea how to correctly do it using Django ORM to make it fast. I suppose for loop over the all unique database dates to get dict for each data will work in this case but it looks very slow solution that will generate thousands of requests. -
Django queryset filtering not providing expected behavior
I have an app taking inputs from a user on the front end. The functionality I'm trying to implement should display all titles on the front end that have reviews <=0, or display NULL values in the database. reviewsign_high = 'lte' if reviewinput_high == '0': review_kwargs = { 'amz_reviews__isnull': True, 'amz_reviews__{}'.format(reviewsign_high): float(reviewinput_high) } titles = titles.filter(**review_kwargs) However, I don't get any results back here. If I remove one parameter, i.e. 'amz_reviews__isnull': True, I do get all titles with reviews less than or equal to 0. Vice versa, if I remove 'amz_reviews__{}'.format(reviewsign_high): float(reviewinput_high), I get all titles with NULL reviews. But them together, displays 0 results. Any ideas on a solution here? Thanks! -
changing color of a particular string in entire html document with Django
Suppose you have a word "day" in 100 sentences in your document. You can change the color of that word in the following way: <span style="color: #ff0000"> day </span> The problem is that you need to do it 100 times. I am using Django and I want to do it inside template with for loop. So, my problem is now to change the color of a string inside some sentence that I don't know what it will be. I tried with something like: def colored(sentence, string, color): if string not in sentence: return sentence else: colored_string = f'<span style="color: {color}"> {string} </span>' colored_string.join(sentence.split(string)) I thought that that will give me colored variable string, but that wasn't the case. It just returned the string '....<span....' without any including the same stuff. It just like it didn't recognized html at all. What is the correct way of solving the same problem? -

Adding data to form before it submits via Javascript in Django
I am working on an app in Django where the user puts in their address and submits it in a form. I need to get this form data, along with its corresponding lat/long, into the views and save it in a model. So, I have used Javascript to call a lat/long API before the form submits and then add that data to the form so all of the data (the address and the lat/long) gets submitted to the server. However, this newly inserted data by Javascript does not show up with the rest of the POST data when submitted. I am not sure why this is. Here is the JS code: const initiate_ride_form = document.querySelector("#initiate-ride-form"); if (initiate_ride_form != null) { document.querySelector("#start-ride-button").onclick = () => { // these are just predecided addresses to simplify the code and isolate this problem const origin = '20%20W%2034th%20St%2C%20New%20York%2C%20NY%2010001' const destination = '1600%20Pennsylvania%Avenue%20NW%2C%20Washington%2C%20DC%2020500'; fetch(`https://api.opencagedata.com/geocode/v1/json?q=${origin}&key=b45938af46624365b08b989268e79d5e`) // Put response into json form .then(response => response.json()) .then(data => { // get the lat and long and save them in variables console.log(data.results[0].geometry); const longitude_origin = data.results[0].geometry.lng; const latitude_origin = data.results[0].geometry.lat; // add the make the hidden input's value equal to the long var input_long_origin = document.querySelector("#from_long"); input_long_origin.value = longitude_origin; // … -

How to precache/load remote postgres DB in django/python for faster testing?

Accessing os files with django inside an electron application
I have a web application built with Django/React. I want to convert it to an electron app and am unsure if I need to refactor some of the backend code to node.js. Here is the relevant information: User needs to create a file with their own API token received from 3rd party. I would like to avoid sending their personal token to my server and want to keep it on their operating system. Django uses the token to query data from the 3rd party api. Django sends data back to front end. My question is, once the application is bundled as an electron app, can django access their api token and query the 3rd party api without hitting my server? Will the django code be run on the localhost (or can it) is I guess what I mean. Thanks, hope this is a valid SO question. -

I checked, on DataBase, and the Users are already there. from django.shortcuts import render, redirect from conta.models import Usuario import secrets from django.contrib.auth import authenticate, login def login_view(request): if request.method == "POST": user = request.POST.get("user") senha = request.POST.get("password") autenticador = authenticate(request, username=user, password=senha) if autenticador is None: context = {"error" : "Invalid username or password"} return render(request, "conta/tela_de_login.html", context) login(request, autenticador) redirect('/admin') return render(request, "conta/tela_de_login.html", {})
