Combining DataTables with Django Ajax Requests
I have a Django project that has a model Analytic that lists analytics. I followed this guide: https://simpleisbetterthancomplex.com/tutorial/2016/11/15/how-to-implement-a-crud-using-ajax-and-json.html to implement Ajax calls, and it worked perfectly. Then, I implemented DataTables to hold the data instead of a regular Bootstrap table. On the surface this worked well, but now the Ajax calls don't work. Instead, saving the create/update forms and deleting a row requires a page refresh for changes to take effect. Here is my JS: $(function () { /* Functions */ var loadForm = function () { var btn = $(this); $.ajax({ url: btn.attr("data-url"), type: 'get', dataType: 'json', beforeSend: function () { $("#modal-analytic").modal("show"); }, success: function (data) { $("#modal-analytic .modal-content").html(data.html_form); } }); }; var saveForm = function () { var form = $(this); $.ajax({ url: form.attr("action"), data: form.serialize(), type: form.attr("method"), dataType: 'json', success: function (data) { if (data.form_is_valid) { $("#analytic-table tbody").html(data.html_analytic_list); $("#modal-analytic").modal("hide"); } else { $("#modal-analytic .modal-content").html(data.html_form); } } }); return false; }; /* Binding */ // Create analytic $(".js-create-analytic").click(loadForm); $("#modal-analytic").on("submit", ".js-analytic-create-form", saveForm); // Update analytic $("#analytic-table").on("click", ".js-update-analytic", loadForm); $("#modal-analytic").on("submit", ".js-analytic-update-form", saveForm); // Delete analytic $("#analytic-table").on("click", ".js-delete-analytic", loadForm); $("#modal-analytic").on("submit", ".js-analytic-delete-form", saveForm); var table = $('#analytic-table').DataTable( { fixedHeader: true, language: { search: "", searchPlaceholder: "Table Search", lengthMenu: "Show _MENU_", }, dom: … -
How do we do signup email confirmation on Google App Engine?
What is the best way to implement signup email confirmation using django-allauth on Google App Engine flexible environment? This seems to be a glaring hole in Google App Engine documentation. Although, there are several links talking about email, none of the documentation gives a complete example that works for us. We've tried sending smtp.gmail.com with our GAE account administrator gmail address without success. This is our Django config: EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend' EMAIL_HOST = 'smtp.gmail.com' EMAIL_HOST_USER = 'our_admin_account@gmail.com' EMAIL_PASSWORD = "'********" EMAIL_PORT = 587 EMAIL_USE_TLS = True DEFAULT_FROM_EMAIL = 'our_admin_account@gmail.com' Even though we have 'our_admin_account@gmail.com' as authorized email sender and disabled captcha. However, this didn't do the trick for us. Also, we have purchased G-Suite because we thought that it would be easier to setup on GAE. We tried using a G-Suite email address to send without any success. This has been quite infuriating and a total waste of our time. We are thinking about moving over to Amazon cloud instead -- but would rather not take the time loss in switching if it could be avoided. We don't want to waste another couple of days trying the other third party email options on GAE--like SendGrid, MailChimp--without knowing whether or not … -
UnicodeDecodeError in Django Raw Query using bytes as parameter
For Django (python3) I am writing a unit test to ensure that a custom encryption routine can be decrypted by MySQL's native aes_decrypt function. start_value = 'A Simple starting test value.' enc_value = mysql_aes_encrypt(start_value, cipher=self.cipher) self.cursor.execute('SELECT aes_decrypt(%s, %s) FROM DUAL', (enc_value, self.test_key)) When executed, this raises the following exception: # -- snip -- File "/home/vagrant/virtualenv/members/lib/python3.6/site-packages/MySQLdb/cursors.py", line 187, in _do_get_result self.description = self._result and self._result.describe() or None UnicodeDecodeError: 'utf-8' codec can't decode byte 0x96 in position 13: invalid start byte When examining the source to execute it seems that after the query executes it attempts to describe the results and dies. I thought maybe I could pass in a column alias to the query as it was having trouble with the bytes there but that didn't work. SELECT aes_decrypt(%s, %s) as foo FROM DUAL In the end, I wrote a stub class that extends cursor and set the cursorclass of the default connection to be that stub. class NoDescriptionCursor(Cursor): """ Testing Cursor """ def _do_get_result(self): """ Our version doesn't try to get descriptions """ db = self._get_db() self._result = self._get_result() self.rowcount = db.affected_rows() self.rownumber = 0 self.description = None # Overridden to run the query. self.description_flags = None # Overridden to … -
How to change Django datetime field format in datepicker?
I have a model field called close_date models.py class Project(models.Model): close_date = models.DateTimeField(blank=True, null=True) In my forms, I don't do add any classes to display this because I will do it in my template using django-widget-tweaks. However, my forms look like this: forms.py class NewProjectForm (ModelForm): class Meta: model = Project fields = ['close_date', ...] templates {% load widget_tweaks %} <div class="form-group" id="close_date"> <label>{{project_form.close_date.label}}</label> <div class="input-group date"> <span class="input-group-addon"><i class="fa fa-calendar"></i></span> {% render_field project_form.close_date class="form-control" type="text" %} </div> </div> <script> $('#close_date .input-group.date').datepicker({ todayBtn: "linked", keyboardNavigation: false, forceParse: false, calendarWeeks: true, autoclose: true }); </script> All this works fine, I can display the form, save it to the database and even display data to the user, but when I want to edit the this object and I populate the form from my views, I see this in the datepicker input field: 2018-02-28 00:00:00 How can I change what is displayed there from 2018-02-28 00:00:00 to 02/28/2018? Is that on the django side of things or the JS side? -
How to connect a Docker container to PostgreSQL running on the localhost using a DATABASE_URL?
I'm following the Aptible Django Quickstart Tutorial which described how to create and deploy an app Aptible's PaaS. I would also like to be able to run the Docker container with the Django app locally and connect to a local PostgreSQL database, however, and it is unclear to me how to do this. The Dockerfile for the Django app is: FROM python:3.6 # System prerequisites RUN apt-get update \ && apt-get -y install build-essential libpq-dev \ && rm -rf /var/lib/apt/lists/* # If you require additional OS dependencies, install them here: # RUN apt-get update \ # && apt-get -y install imagemagick nodejs \ # && rm -rf /var/lib/apt/lists/* # Install Gunicorn.

Celery task to write file in subprocess
There is a celery task to call subprocess and in the subprocess script, I want to write some text in file (auth_path) each function in script done. The problem is, if I call python3 apt.py from shell, text written in the file. but when i call subprocess in task, progress works correctly, all functions works in apt.py but nothing written in aut_path. Why I cannot write some texts when I call script from subprocess. @task(name="dene") def dene(): cmd = ['timeout', '240', 'python3', "apt.py"] output = check_output(cmd) in apt.py there is a write func and calling it again and again. def write_out_auto(msg): with open(aut_path, 'a') as the_file: the_file.write(msg +'\n') write_out_auto("Finished the section 2") -

Django: trying to link to one model inside of other models ListView
I would like to get the Restaurant Id from the Restaurant model and use it for the href in the Lunchmenu listview. Don´t really know how to move forward from here. I have tried a for loop of the "restaurants_list" in the template but did not really understand how to get only one Id from the list. Is there any way to do this in the template?

Bug Update Django Formsets
I am trying to modify a sale in which I have this view: #Views.py class VentaUpdate(UpdateView): model = Venta template_name = 'venta/venta_form.html' form_class = VentaForm success_url = reverse_lazy('venta:ventas_listar') def get_context_data(self, **kwargs): data = super(VentaUpdate, self).get_context_data(**kwargs) if self.request.POST: data['detalleformset'] = DetalleFormSet(self.request.POST, instance=self.object) else: data['detalleformset'] = DetalleFormSet(instance=self.object) return data def form_valid(self, form): context = self.get_context_data() detalleformset = context['detalleformset'] with transaction.atomic(): self.object = form.save() if detalleformset.is_valid(): detalleformset.instance = self.object detalleformset.save() return super(VentaUpdate, self).form_valid(form) It works correctly in these cases: 1. Edit a product (if it was 1 soda, replace it with 1 water). 2. Add another product. But it does not work to want to eliminate a product from the sale. #forms.py class DetalleForm(forms.ModelForm): class Meta: model = DetalleVenta fields = [ 'producto', 'cantidad', 'subtotal', ] labels = { 'producto':'Producto', 'cantidad':'Cantidad', 'subtotal':'Subtotal', } widgets = { 'producto':forms.Select(attrs={'class':'form-control'}), 'cantidad':forms.NumberInput(attrs={'class':'form-control'}), 'subtotal':forms.NumberInput(attrs={'class':'form-control'}), } DetalleFormSet = inlineformset_factory(Venta, DetalleVenta, form=DetalleForm, extra=1) And so that the formset is dynamic, that is to be able to add more fields which I think the error is from the Javascript but I can not find the error {% extends 'base/base.html' %} {% load static %} {% block titulo%} Registrar venta {%endblock%} {% block contenido %} <form method="post"> {% csrf_token %} <div class="col-md-4 … -

Django session dictionary KeyError when attempting to replace
I am dealing with a third-party authorization issue on the backend and encountering strange session store behavior. When I detect that the third part session authorization has become invalid, I re-authenticate and I am attempting to update the data in the session, which is not working. The problem is that after I delete the key from the session, I get a KeyError when I try to replace it once I have the updated information. def my_session_thing(invalidate=False): if invalidate: del self.request.session['my_session_dict'] self.request.session.modified = True my_session_dict = self.request.session.get('my_session_dict') if my_session_dict is not None: self.current_session_dict = my_session_dict return my_new_session_dict = { 'foo': 'bar' } # ** Why does this raise a KeyError when invalidate is True? ** self.request.session['my_session_dict'] = my_new_session_dict I am currently exploring alternatives to this strategy, but I found this behavior contradicts the dictionary-like behavior that the "How to use sessions" documentation describes, so it would be worth posting. -

Django App Running on Google App Engine Flexible environment cannot send mail
Can anyone tell me how to configure a Django app running on Google App Engine Flexible environment to send out emails? We are trying to send confirmation emails to users (we are using django-allauth) during account/signup. Our attempts to configure App Engine for send mail is not working. We have waisted four whole days on this supposedly simple matter. This is our current Django settings: EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend' EMAIL_HOST = 'smtp.gmail.com' EMAIL_HOST_USER = 'my_email_address@gmail.com' EMAIL_PASSWORD = "'********" EMAIL_PORT = 587 EMAIL_USE_TLS = True DEFAULT_FROM_EMAIL = 'my_email_address@gmail.com' The account 'my_email_addres@gmail.com' is actually the email that is used to setup the App Engine instance. On App Engine console, we configured 'my_email_address@gmail.com' as the authorized email sender. We verified that we can successfully log into both App Engine and Gmail with our 'my_email_address' and password we provided in the Django Settings file. However, when users attempt to signup, the sendmail step fails with the following error message (I edited the server url and email address edited below): SMTPSenderRefused at /accounts/signup/ (530, b'5.5.1 Authentication Required.

Django - Search matches with all objects - even if they don't actually match
This is the model that has to be searched: class BlockQuote(models.Model): debate = models.ForeignKey(Debate, related_name='quotes') speaker = models.ForeignKey(Speaker, related_name='quotes') text = models.TextField() I have around a thousand instances on the database on my laptop (with around 50000 on the production server) I am creating a 'manage.py' function that will search through the database and returns all 'BlockQuote' objects whose textfield contains the keyword. I am doing this with the Django's (1.11) Postgres search options in order to use the 'rank' attribute, which sounds like something that would come in handy. I used the official Django fulltext-search documentation for the code below Yet when I run this code, it matches with all objects, regardless if BlockQuote.text actually contains the queryfield. def handle(self, *args, **options): vector = SearchVector('text') query = options['query'][0] search_query_object = SearchQuery.objects.create(query=query) set = BlockQuote.objects.annotate(rank=SearchRank(vector, query)).order_by('-rank') for result in set: match = QueryMatch.objects.create(quote=result, query=search_query) match.save() Does anyone have an idea of what I am doing wrong? -
