Perform translation (internationalization) using ugettext_lazy in models.py for a dynamic variable
I have a django project where there are multiple models defined and each model have some set of fields with choice fields. These values are being displayed on template using a loop. I have multiple languages defined and using ugettext_lazy, I am able to show the translated value as per the language selected by user. Now I am trying to move these values into database, fetch them and use it in ugettext_lazy for translation. e.g. _(value_from_db) Problem is when using from database, the value doesn't translate whereas when using it as hardcoded e.g. _("translated_val") models.py from django.utils.translation import ugettext_lazy as _ from translated_fields import TranslatedField class ModelClass(models.Model): choices_values = ( (dataframe[(dataframe['name'] == 'State1')]['code'].item(), _("State1")), (dataframe[dataframe['name'] == 'State2']['code'].item(), _(dataframe[dataframe['name'] == 'State2']['value'].item())), (State3, _("State3")) ) In the above example, the translation works properly for State1, State3 but not for State2. I expect State2 to be translated on my template. P.S. All the translation activities have been done properly and are working (if I replace the dataframe fetch for state2 with hardcoded value, it gives the proper tranlation and also the dataframe fetches the same value as the one I had hardcoded) Thanks for the help. -
Weasyprint not rendering images in production

Is there a way to execute html inside of a template variable that is a table?
I am creating a website using Django and I have taken a pandas dataframe and stored it as a template variable and passed it to the render request. I would like to make some columns form elements but have been unsuccessful into how to do that. I have already tried applying the function to the pandas dataframe in order to add the proper HTML to each element in the column. However, the HTML itself shows up on the actual site. Here is my python code: def optimizer(request): df = Optimizer.get_daily_roster('E:\website\optimizer\Predictions.csv') df = df.drop(columns=['Name + ID', 'Game Info', 'Unnamed: 0', 'Unnamed: 0.1', 'name']) df = df.rename(columns={'TeamAbbrev': 'Team', 'AvgPointsPerGame': 'Predicted FP'}) df['Predicted FP'] = df['Predicted FP'].apply(lambda x: round(float(x), 2)) df['Predicted FP'] = df['Predicted FP'].apply(lambda x: "<input type='text' value=" + str(x) + ">") df['Min Exposure'] = 0 df['Max Exposure'] = 1 # cols_to_values = df.to_dict(orient='list') # cols_to_values = {x.translate({32: None}): y # for x, y in cols_to_values.items()} html_table = df.to_html(index=False, justify='left', classes=[ 'table table-bordered table-striped table-hover table-responsive table-sm, container-fluid']) return render(request, 'optimizer/optimizer.html', {'player_table': html_table}) And here is my HTML: {% extends "optimizer/base.html" %} {% block content %} <h1>Optimizer</h1> <form method="post"> <input type="submit" value="Generate Lineups"> <div class="table-responsive"> {{ player_table |safe }} </div> </form> {% … -

How to add different models to only one model in django?
I have some models that are used to make one order per dining table. My goal is to have different dining tables, these always have a total order and the total order has individual orders. I have difficulties when i create a second dining table, with a second total order, to avoid taking orders (relationship) from the first table. How can i make a total order that has his own orders, without any relationships from other orders? Here my models: class Order(models.Model): Beer = models.ForeignKey(Beer, on_delete=models.SET_NULL, blank=True, null=True, related_name='beer') SoftDrink = models.ForeignKey(SoftDrink, on_delete=models.SET_NULL, blank=True, null=True, related_name='soft_drink') ForeignBeer = models.ForeignKey(ForeignBeer, on_delete=models.SET_NULL, blank=True, null=True, related_name='foreign_beer') Liquor = models.ForeignKey(Liquor, on_delete=models.SET_NULL, blank=True, null=True, related_name='liquor') Wine = models.ForeignKey(Wine, on_delete=models.SET_NULL, blank=True, null=True, related_name='wine') BarDrink = models.ForeignKey(BarDrink, on_delete=models.SET_NULL, blank=True, null=True, related_name='bar_drink') Meal = models.ForeignKey(Meal, on_delete=models.SET_NULL, blank=True, null=True, related_name='meal') class TotalOrder(models.Model): Order = models.ManyToManyField(Order, related_name='order') Total_Price = models.DecimalField(default=0, max_digits=6, decimal_places=2) class Table(models.Model): Number = models.IntegerField(unique=True) Total_Order = models.ForeignKey(TotalOrder, on_delete=models.SET_NULL, related_name='total_order', blank=True, null=True) Thanks in advance :D -

Set GOOGLE_APPLICATION_CREDENTIALS environment variable in VSCode debugger
I'm testing Google Cloud Pub/Sub on my Django project using VSCode on my Mac, and I'm having some problems setting GCP environment variables during debugging tests, specifically the GOOGLE_APPLICATION_CREDENTIALS environment variable. I am able to set the GOOGLE_APPLICATION_CREDENTIALS for running server and/or tests locally with export GOOGLE_APPLICATION_CREDENTIALS="path/to/json_credential_file.json" in a shell, but as the VSCode debugger runs in a separate shell the env variable is not set when debugging tests. I tried adding the same value to the env key in launch.json: "env": { "GOOGLE_APPLICATION_CREDENTIALS": "path/to/json_credential_file.json" } But it still complains about GOOGLE_APPLICATION_CREDENTIALS not being set: oauth2client.client.ApplicationDefaultCredentialsError: The Application Default Credentials are not available. They are available if running in Google Compute Engine. Otherwise, the environment variable GOOGLE_APPLICATION_CREDENTIALS must be defined pointing to a file defining the credentials. See https://developers.google.com/accounts/docs/application-default-credentials for more information. Any ideas? -
Django multiple ModelForms from one Model
I need to implement a transaction with a step by step process wherein the user can input the details in step 1 and then process the inputted data which will do some calculations. The user can then proceed to step 2 which displays the initial result and he/she can input additional parameters to manipulate the results. I need to store all user inputs in one model so that if the user cancels the process, all data that was initially stored will be deleted. I am a newbie in django and python so if anyone know how to solve this problem I would really appreciate it. This is what I've tried so far: In my models.py I have: class Calculate(models.Model): date_created = models.DateField(auto_now_add=True) user = models.ForeignKey(get_user_model(), on_delete=models.CASCADE) csv = models.FileField(upload_to='files/') param1 = models.CharField() param2 = models.CharField() param3 = models.CharField() In my forms.py I have: class DetailsInputForm(forms.ModelForm): class Meta: model = Analysis fields = ('date_created', 'csv',) class ParamInputForm(forms.ModelForm): class Meta: model = Analysis fields = ('param1', 'param2', 'param3',) In my views.py I have: class DetailsInputView(LoginRequiredMixin, CreateView): model = Calculate form_class = DetailsInputForm template_name = 'step1.html' login_url = 'login' success_url = reverse_lazy('step2') class ParamInputView(LoginRequiredMixin, CreateView): model = Calculate form_class = ParamsInputForm template_name = … -

How to setup a Django-site where users have different permissions for different projects
Kind stacky! Hopefully you can help me out. I'm trying to workout a framework on which I can relatively easily develop django-apps and distribute them to the users. Users can use these apps within a 'project' environment, so the data they see in that app is only related to the project they are currently looking at. I'm not referring to Django-projects here, but projects as in a task on which multiple people are working together. :) Users should be able to create a project and invite other users. If a user has no permission for a certain project he cannot access the project. Questions that are spooking through my head are: How do I need to setup my model? How do I go about setting up permissions? How do I make sure they can not access project data to which they don't have permissions. I understand there is not one true solution, but I am looking for recommendations on best practices or working examples. I just don't know how to start. I already searched the internet extensively but I can't find anything that resembles what I want to do. My line of thought currently is to create a project class … -

Django application server requirement with ubuntu + apache + mod_wsgi
I need your guidence on setting up my production server for django application. Below are the details of my application . Its a simple website which connects 3 database/applications that is already available in 3 separate VM's. The 3 applications are: 1) MSSQL database(which will provide details of a parent table(model) and 15 or 20 child tables(model). when each record from the parent model is opened it fetches the details of other child tables and display them in the page) 2) Document management system to stream the files(average of 10 files with each documents with 150-200 kb size of each document) related to the records that are fetched with the previous step. 3) Mysql database (which will give few more details related to the parent model from the parent model) Now my new VM which we are going to setup should have a simple RDBMS created with postgreg to hold the basic details of django and the website users along with python and django. The current user base is 5-6 users at a time and may grow to 10 -12. Can some one recommend a capacity planning for the above requirement for DJANGO+ UBUNTU + APACHE + MOD_WSGI( please suggest … -

Django urls.py: best way to not have a page number in the first page of a list view?
Right now I have a list view that displays 10 posts per page: The urls would be something like this: www.example.com/posts/1 (First page with 10 results) www.example.com/posts/2 (Next page with 10 results) and my urls.py looks something like this: path('posts/<int:page>', PostList.as_view(), name='post-list'), I want to be able to have the first page of posts also visible when there is no number, for example: www.example.com/posts (First page with 10 results) The only way that I have been able to solve this is by adding another line in the urls.py that points to the same view and that has the same name. path('posts', PostList.as_view(), name='post-list'), path('posts/<int:page>', PostList.as_view(), name='post-list'), Is this the appropriate way of doing this or is there a better way?

Django AJAX working but test case failing in POST request
So I have this unit test: def test_delete_product(self): self.api_client.login(username=self.username, password=self.password) path = self.get_url_for_test_against_endpoint('/product/delete/') data = {'id': self.product.id} response = self.api_client.post(path=path, data=json.dumps(data), content_type='application/json') self.assertEqual(response.status_code, 302) self.assertFalse(Product.objects.filter(id=self.product.id).exists()) and this view def post(self, request): pid = request.POST.get('id') get_object_or_404(Product, id=pid).delete() return redirect('product:products') My entry in urls.py is path('product/delete/', product_delete_view, name='product_delete') The AJAX I am using to call this view is: <script> const url = "{% url 'product:product_delete' %}" var id = "{{ product.id }}" var intId = parseInt(id) const data = { id: intId, csrfmiddlewaretoken: '{{ csrf_token }}' , contentType:'application/json'} $('#{{ product.id }}').click(function () { $.post(url, data, function (data, status) { console.log(`${data} and status is ${status}`) location.reload(true) }) }) </script> What works: When I call this view through ajax, everything works fine and the product is deleted. What does NOT work When I run the test, it fails because response.status_code returns 404. While trying to find out what the problem is, I used pdb.set_trace() in view and I found that request.POST.get('id') returns None. If I hard code pid to 1 test case passes which means in the view, it is unable to get id from the request which is weird because it is able to do that same through ajax call. If I do … -

Django NoReverseMatch when trying to logout
I have a django view function signout that I want to call form a form/template. When i click logout, it calls the function but the redirect after doesnt work. I get the message Reverse for '<WSGIRequest: POST '/account/signout'>' not found. '<WSGIRequest: POST '/account/signout'>' is not a valid view function or pattern name. Urls.py urlpatterns = [ path('register', views.register, name='register'), path('login', views.login, name='login'), path('signout', views.signout, name='signout'), path('dashboard', views.dashboard, name='dashboard'), ] Views.py def signout(request): if(request.method == 'POST'): auth.logout(request) messages.success(request, 'You are logged out!') return redirect(request, 'index') Template form <form action="{% url 'signout'%}" id="logout" method="POST"> {% csrf_token %} <input type="hidden"> <button type="submit" class="btn btn-primary btn-sm"><i class="fas fa-sign-out-alt"></i> Log Out</button> </form> What is going wrong?? The rest of routes work just fine and they are declared the same as signout.
