How to process every line of an output in python django
Sorry if the subject is not clear enough. This is my urls.py in Django: from django.contrib import admin from django.urls import path # imported views from cron import views urlpatterns = [ path('admin/', admin.site.urls), # configured the url path('',views.index, name="homepage") ] This is views.py: from django.http import HttpResponse from subprocess import * import codecs def index(request): with open('/home/python/django/sites.txt', 'r') as file: for site in file: with open('output.html', 'a') as file2: out = run(["ssh", "-o StrictHostKeyChecking=accept-new", "-p1994", f"root@{site}".strip(), "crontab", "-l"], capture_output=True) out = out.stdout out = codecs.decode(out, 'unicode_escape') file2.write(str(f'Server is: <span style=\'font-weight:bold\'>{site.strip()}</span>')) file2.write(str(rf'<p>{out}</p>')) file2.write('\n') with open('output.html', 'r') as new: return HttpResponse(new) This is sites.txt: 1.1.1.1 2.2.2.2 3.3.3.3 This is the output.html in text editor: Server is: <span style='font-weight:bold'>1.1.1.1</span><p>#30 16 * * * /usr/bin/bash /home/backup/ftp 0 0 * * * /usr/bin/bash /home/backup/ftp > /dev/null 2>&1 </p> Server is: <span style='font-weight:bold'>2.2.2.2</span><p>#30 16 * * * /usr/bin/bash /home/backup/ftp 0 0 * * * /usr/bin/bash /home/backup/ftp > /dev/null 2>&1 </p> Server is: <span style='font-weight:bold'>3.3.3.3</span><p>#30 16 * * * /usr/bin/bash /home/backup/ftp 0 0 * * * /usr/bin/bash /home/backup/ftp > /dev/null 2>&1 </p> I know this HTML format is not correct to show properly in web, but I don't know how to make it better so that … -
Should I use regular SQL instead of an ORM to reduce bandwith usage and fetching time?
I'm building a ethereum explorer for fun with django ORM (never used it before). here is a part of my schema : class AddressModel(models.Model): id = models.BigIntegerField(primary_key=True) first_seen = models.DateTimeField(db_index=True) addr = models.CharField(max_length=42, db_index=True, on_delete=models.PROTECT) is_contract = models.BooleanField() is_token = models.BooleanField() is_wallet = models.BooleanField() class BlockModel(models.Model): id = models.BigIntegerField(primary_key=True) number = models.BigIntegerField() status = models.CharField(max_length=20) timestamp = models.DateTimeField(db_index=True) epoch_proposal = models.IntegerField() slot_proposal = models.IntegerField() fee_recipient = models.ForeignKey(AddressModel, on_delete=models.PROTECT) block_reward = models.BigIntegerField() total_difficulty = models.CharField(max_length=100) size = models.IntegerField() gas_used = models.BigIntegerField() gas_limit = models.BigIntegerField() base_fee_per_gas = models.BigIntegerField() burnt_fee = models.BigIntegerField() extra_data = models.TextField() hash = models.CharField(max_length=66) parent_hash = models.CharField(max_length=66) state_root = models.CharField(max_length=66) withdrawal_root = models.CharField(max_length=66) Nonce = models.CharField(max_length=20) # you can do address_model_instance.transactionmodel_set.objects.all() since there is a FK in Transaction model class TransactionModel(models.Model): id = models.BigIntegerField(primary_key=True) hash = models.CharField(max_length=66) block = models.ForeignKey(BlockModel, on_delete=models.PROTECT) from_addr = models.ForeignKey('AddressModel', related_name='from_addr', on_delete=models.PROTECT) to_addr = models.ForeignKey('AddressModel', related_name='to_addr', on_delete=models.PROTECT) input = models.TextField() is_valid = models.BooleanField() What concerns me here is that if I want to retrieve every transaction related to a specific from_addr it will also retrieve the bloc data in the returned object, if the from_addr has 10K transaction that is 10K block data that I don't need. with regular SQL I would only get a … -
django-nested-admin nested model initial values
I've been working with django-nested-admin for editing admin models that have foreign key relationships to other tables. Frankly it's beautiful. I love it. But I have a pair of models here I'm having a bit of trouble with. I have a Chapter, representing a chapter of a club. Each chapter has a one or more useful links to things like their web page or wiki articles or whatever. Both classes have a field of 'registrar' which is the user that created them. Basically whoever was logged in to the system when the instance was created. For Chapter, this went fairly easily. I just added def get_changeform_initial_data(self, request): get_data = super(ChapterAdmin, self).get_changeform_initial_data(request) get_data['registrar'] = request.user.pk return get_data To the ChapterAdmin class. It pre-populates just fine. But when I tried to do the same with the UsefulLinksInline, that ChapterAdmin uses. I've been down a rabbit hole of googling and break-point surfing trying to figure out how to pre-populate the UsefulLink class's registrar field with the current user. In UsefulLinksInline, if I remove the registrar field from the fields=() list, I get an error stating that the null constraint on registrar was being violeted. If I leave it in, however, the Registrar combo … -
Where to host Django project files on deployment server
New to Django here. I have developed a minimum working django website with Postgres as database back-end and nginx/gunicorn as web server on Ubuntu linux. Currently all the files are on my laptop in ~/workspace/djangoapp/src$ in my home directory. I want to now deploy the project to GCP. Which directory, on the production server, the files would go in? It can't be my home directory on the production server. Shouldn't they go in one of the system directories like /opt? -
How to prevent auto-filling of other Django forms when updating a specific form and how to make them not required to fill?
I have some Django forms each one with an update button that I'm rendering on a template. When I try to submit something through the button I can't because It says I have to fill every form. I also run into the problem that when I try to update a form the value in the other forms changes and auto-fills. forms.py class ImageUpdateForm(forms.ModelForm): image = forms.ImageField(widget=forms.FileInput) class Meta: model = User fields = ['image', 'mnemonic'] def clean(self): super(ImageUpdateForm, self).clean() mnemonic = self.cleaned_data.get('mnemonic') if mnemonic != self.instance.mnemonic: self._errors['mnemonic'] = self.error_class([ 'The mnemonic is wrong!']) return self.cleaned_data class PasswordUpdateForm(forms.ModelForm): class Meta: model = User fields = ['password', 'mnemonic'] def clean(self): super(PasswordUpdateForm, self).clean() mnemonic = self.cleaned_data.get('mnemonic') if mnemonic != self.instance.mnemonic: self._errors['mnemonic'] = self.error_class([ 'The mnemonic is wrong!']) return self.cleaned_data class PinUpdateForm(forms.ModelForm): class Meta: model = User fields = ['pin', 'mnemonic'] def clean(self): super(PinUpdateForm, self).clean() mnemonic = self.cleaned_data.get('mnemonic') if mnemonic != self.instance.mnemonic: self._errors['mnemonic'] = self.error_class([ 'The mnemonic is wrong!']) return self.cleaned_data class MnemonicUpdateForm(forms.ModelForm): class Meta: model = User fields = ['mnemonic', 'password'] def clean(self): super(MnemonicUpdateForm, self).clean() password = self.cleaned_data.get('password') if password != self.instance.password: self._errors['password'] = self.error_class([ 'The password is wrong!']) return self.cleaned_data views.py def UpdateView(request): user = request.user if request.method == 'POST': mnemonic_form = … -
Implementing Name Synchronization and Money Transfers in Transactions Model with Account Number Input
I have the following models in my Django application: class Transaction (models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE) account_number = models.IntegerField() name = models.CharField(max_length=50) amount = models.DecimalField() created_on = models.DateTimeField() class Wallet(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE) account_balance = models.DecimalField(default=0) class AccountNum(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE) account_number = models.IntegerField() slug = models.SlugField(unique=True) I want to implement a feature where the name field in the Transactions model gets synchronized with the account owner's name based on the provided account_number input. Additionally, I want to enable money transfers using the current user's wallet and the specified amount in the Transactions model. To provide some context, I have a post-save signal generate_account_number which generates a random 6-digit account number and creates an AccountNum object for a newly created user. What are some recommended techniques or approaches to achieve this synchronization of the name field with the account owner's name and enable money transfers using the wallet model and specified amount in the Transaction model? -

Advice for developing a ticket selling platform for events
I'm a junior developer with little experience from Argentina. I have done courses in JavaScript, CSS, React, python, django and SQL. I want to develop a platform for selling tickets for events. In the beginning, it will be basic to show in my portfolio but I want to continue developing until it gets fully functional and advanced to be used as a real business. The platform need user registration with many profiles like “Promoters” who can create events, manage them, take statistics, “Final users” who can buy tickets from all the events already created, see all the bought tickets, transfer tickets to another users and “Sellers” who can be assigned to events by promoters to sell tickets through a personalized link (which can be traceable). When users log-in there should be a kind of a dashboard with all the functions mentioned before (and more). The home page will be basic, with cards of all the uploaded events. Before I start the project, I want to be sure that I'm using the correct technologies and that everything is scalable because like I said before the mid-term objective is that it gets real. I was thinking of using React and maybe Next.JS … -

Why does django url tag with argument work in VS Code but not Visual Studio 2019?
I have a simple django app built in Visual Studio 2019 using python. I am trying to use a url template tag to open a record in a form on another page in order to update that record but it always returns: 'reverse not found...' This is the template tag (uform.id is the argument): <td><a href="{% url 'app:form-update' uform.id %}">{{ obj.form_name }}</a></td> The url paths: from django.urls import path from app import views app_name = 'app' urlpatterns = [ path('', views.home, name='home'), path('form-create/', views.create_form, name='form_create'), path('form-update/<str:pk>/', views.updateForm, name='form-update'), ] The view: def updateForm(request, pk): uform = Forms.objects.get(id=pk) form = FormRegisterForm(instance=uform) if request.method == 'POST': form = FormRegisterForm(request.POST, instance=uform) if form.is_valid(): form.save() return redirect('app:form_register') context = {'form': form} return render(request, 'app/form_create.html', context) When I replace the id argument in the url template tag with an id such as 19, it works without error. This suggests the syntax of the url template tag is wrong, however the same syntax works in other apps I have created using VS Code. I don't understand why it won't work in Visual Studio 2019. Any help would be greatly appreciated. -

Bootstrap-table data clears on search, filter or paginate after Ajax call
In my Django template I have a bootstrap-table (version 1.21.2) (https://bootstrap-table.com/) which is filled with multiple customers, whenever a customer is clicked, it will create a popup with a bootstrap-table in which all data for that customer is displayed using Ajax. The problem, is that, whenever I try to search, filter or paginate, it clears the entire table. I think this is because bootstrap-table clears the entire table, and then refills it with whatever you're trying to search. Here is my code: Ajax: function get_customer_leadtime(customerCode, customerName, warehouse) { $.ajax({ type:"GET", url: "{% url 'get_customer_leadtime' %}", data:{ "customerCode": customerCode, "customerName": customerName, "warehouse": warehouse }, success: function (response) { var title = customerName var table = $("#customerLeadtimeTable tbody"); document.getElementById("customerLeadtimeLabel").innerHTML = title; table.empty() $.each(response, function(idx, customerInfo){ $.each(customerInfo, function(_, details){ table.append( "<tr><td>"+details.Article +"</td><td>"+details.Leadtime +"</td></tr>" ); }); }); $("#customerLeadtimeModal").modal('show'); }, error: function (response) { console.log(response) } }); } Ajax GET example URL: GET /get/ajax/leadtime?customerCode=00000&customerName=SomeCustomer%20BV&warehouse=SomeLocation HTTP/1.1" 200 9216 HTML: <table class="table table-hover table-sm" id="customerLeadtimeTable" data-toggle="table" data-show-multi-sort="true" data-show-search-clear-button="true" data-show-export="true" data-search="true" data-filter-control-multiple-search="true" data-filter-control="true" data-search-align="left" data-pagination="true" data-side-pagination="client" data-page-size="10" data-page-list="[10, 25, 50, ALL]" data-click-to-select="true" data-show-toggle="true" data-show-columns="true" > <thead> <tr> <th scope="col" data-field="Article" data-width="50" data-width-unit="%">Article</th> <th scope="col" data-field="Leadtime" data-width="50" data-width-unit="%">Average leadtime</th> </tr> </thead> <tbody> <tr> </tr> </tbody> </table> Image of the … -
Add a OnetoOne field in an already populated Django ORM
I have this customer model where I want to introduce a user field where the user field is user = models.OneToOneField(User, on_delete=models.CASCADE) but there are already some objects in this model so if i create this one to one field then it would ask me for a default value for those objects but I cannot pass default values because it'll clash with the logic.

How to test async django rest framework
I have a problem with testing async mode in the django rest framework using the adrf library.
