when I try to send an e-mail from my Contact page, I get this error. How Can I Solve? I am getting this error on ubuntu server and in addition, these codes work in localhost without any problems.

Django employer employee relationship
I'm having bit of a trouble with how to structure One Employer to many Employees relationship in Django when employees need to login too. My initial set is only employers are users and employees don't login and here is that setup: from django.contrib.auth.models import User class Company(models.Model): user = models.OneToOneField( User, on_delete=models.CASCADE, primary_key=True) company_name = models.CharField(max_length=100, blank=False, null=True) ... class Employee(models.Model): user = models.ForeignKey( User, on_delete=models.CASCADE, null=True, related_name='employees') full_name = models.CharField(max_length=50, null=True, blank=True) .... But now I made a mobile app and employees need to login as well. I'm managing the auth with JWT, Back-end (Django) with Graphene (So GraphQL) and mobile app with Apollo client. Question is: How do I create a User account (in auth_user table, which is what JWT uses for authentication) for employees while still maintaining the foreignKey relationship to the company? -

LOGIN_REDIRECT_URL not redirecting
I'm using Django, Mysql and Docker, with a custom user model for Django. After entering correct login details the LOGIN_REDIRECT_URL='searcher-home' variable in settings.py isn't redirecting to the home page as expected, instead it attempts to redirect to the default path of /accounts/profile/. Does anyone know what could be causing this? I've looked elsewhere for answers, but all issues I've found are either looking for LOGIN_URL which isn't what I need, or are using custom LoginViews, which I'm not. Any insight would be appreciated. -
Django X-editable
and thank you for always saving me in my project :D I am using django to develop my app and here is the page I have basically displaying a table : Html code here : <table class="logtable" > <tr> <td> Year </td> <td name="yearr">{{ yearr }}</td> </tr> <tr> <td> Plant </td> <td>{{ plant }}</td> </tr> <tr> <td>Responsible</td> <td>{{responsible}}</td> </tr> <tr> <td>Produced sales in Km per week</td> <td>{{produced}}</td> </tr> <tr> <td>Sold sales per Week (m)</td> <td>{{sold}}</td> </tr> <tr> <td>Number of customers </td> <td>{{customers}}</td> </tr> <tr> <td>Number of produced references </td> <td>{{references}}</td> </tr> <tr> <td>Shipment destinations </td> <td>{{destinations}}</td> </tr> <tr> <td>Plant shifts </td> <td>{{shifts}}</td> </tr> </table> I would like to to be able to double click a td to change its value and save into the database, I think x-editable allows me to do that, can someone help me on how to do it ?

JSON parse error - Expecting value: line 1 column 1 (char 0) - DELPHI Rest Datasnap
I'm trying to make a POST request in the delphi language, as a client and Django as a server. But when doing the POST is giving the error: { "detail":"JSON parse error - Expecting value: line 1 column 1 (char 0)" } All the authentication part is working correctly, I can make GET requests without problems. Source code used to add my json to the body of the request. sJson := '{"id":9,"grupo":"TESTE","id_empresa":26,"prioridade":0}'; RESTRequest.Body.ClearBody; with RESTRequest.Params.AddItem do begin name := 'body'; Value := sJson; Kind := pkREQUESTBODY; ContentType := ctAPPLICATION_JSON; end; RESTRequest.Execute; Result.Value := RESTResponse.content; Result.StatusCode := RESTResponse.StatusCode; Result.Mensagem := RESTResponse.StatusText; Making the same request through PostMan everything goes well, but not when I do it through my application. Would anyone know the resolution of this ?? -

Django Models: How to pass the id of a class, and the non-null object fields of a class to another class?
This is a conceptual question, not an error necessarily. How do I differentiate between drawing the autogenerated id of a class and drawing the name of non-null object fields in a class? For example, in my class Source, I have: class Source(models.Model): profile = AutoOneToOneField(User, on_delete=models.CASCADE, null=True) project= AutotOneToOneField(Project, on_delete=models.CASCADE, null=True) team =AutotOneToOneField(Team, on_delete=models.CASCADE, null=True) department = AutoOneToOneField(Department, on_delete=models.CASCADE, null=True) def __str__(self): return self.profile + self.project + self.team + self.department and the goal is to have the source either be from a profile, project, team, or department, and I want to associate that source with a a sourceID, but I also want to be able to know the type of source. In my class, VideoPost: class VideoPost(models.Model): sourceID = models.ForeignKey(Source, on_delete=models.CASCADE) postID = models.ForeignKey(Post, on_delete=CASCADE) I want to draw the sourceID, but in my class Following: class Following(models.Model): profile = AutoOneToOneField(User, on_delete=models.CASCADE) account_types = models.ForeignKey(Source, on_delete=models.CASCADE) #need to create an account type account_ids = models.PositiveIntegerField() following_objects = GenericForeignKey('account_types', 'account_ids') def __str__(self): return self.profile + 'is following' I want to draw the type of source (in account_types). How do I differentiate and return the values desired? -
Add divs with Django template tags on button press
I have a simple form defined in forms.py: SAMPLE_STRINGS = [('','Select...'),'aa','ab','bb','c0'] class MyCustomForm(forms.Form): chosen_string = forms.ChoiceField(choices=SAMPLE_STRINGS, label='Please select a string', required=True) chosen_number = forms.IntegerField(label='Please select an integer', widget=forms.NumberInput(attrs={'placeholder': 0})) I want to allow the user to add boxes (divs) containing the above form. One standalone div, with Django's template tags, would look like this: <div class="box" style="height:auto; background-color: #eee;"> <form method="POST" action=""> {% csrf_token %} {{form.as_p}} </form> </div> I know that, if there is a button <button class="add_box">New Box</button>, the corresponding jQuery script to add new elements would look like this: $('#button_id').click(function(){ $('#canvas').append(' ...*HTML of element*... '); }); However, this jQuery doesn't seem to work when the element to be appended doesn't contain pure HTML/CSS but also Django templates. My views.py: def my_form_func(response): form = MyCustomForm(response.POST or None) return render(response, "main/my_custom_form.html", {"form": form}) my_custom_form.html: <link rel="stylesheet" href="//code.jquery.com/ui/1.12.1/themes/base/jquery-ui.css"> <script src="https://code.jquery.com/jquery-1.12.4.js"></script> <script src="https://code.jquery.com/ui/1.12.1/jquery-ui.js"></script> <script> $( function() { $( ".box" ).draggable().resizable(); } ); // adding div and form on button click - this part causes error $('.add_box').click(function(){ $('#canvas').append('<div class="box" style="height:auto; background-color: #eee;"><form method="get" action="">{% csrf_token %}{{form.as_p}}</form></div>'); }); </script> <html> <button class="add_box">New Box</button> <div id="canvas" style="background-color: #444; height: 90%"> <div class="box" style="height:auto; background-color: #eee;"> <form method="POST" action=""> {% csrf_token %} {{form.as_p}} </form> </div> </div> … -

django not applying css and widget after form fail
I am trying to apply CSS to input fields after form failure. The ModelForm where I am applying the original CSS and widget is: class MyAppForm(ModelForm): class Meta: widgets = { 'date_field': DateInput(attrs={"type": "date"}) } def __init__(self, *args, **kwargs): super(MyAppForm, self).__init__(*args, **kwargs) for i, f in self.fields.items(): f.widget.attrs['class'] = 'custom-css' The template where I'm redisplaying the form looks like this: {{ myapp_form.date_field.errors }} <label for="{{ myapp_form.date_field.id_for_label }}">{{ myapp_form.date_field.label }}</label> {{ myapp_form.date_field }} After the form is redisplayed, the date field displays as text input is custom-css are not applied to the input elements.

Suggestion on model test
I’ve been thinking about changing my simple model creation test from this. def test_create_user(self): user = User.objects.create_user( email='normal@user.com', password='foo', # other fields ) assert user.email == 'normal@user.com' # assert other fields To this def test_create_user(self): user = UserFactory.create() assert isinstance(user, User) I’m not sure if they represent the same thing, but I think the second one is easier to read. I would like to know suggesting about this kind of test, since I’m pretty new to testing thing. Thanks for your attention. -

Django forms: new fields whenever field value is changed?
In my forms.py I have a simple form defined, with an integer and a choice field: SAMPLE_STRINGS = [('','Select...'),'aa','ab','bb','c0'] class MyCustomForm(forms.Form): chosen_string = forms.ChoiceField(choices=SAMPLE_STRINGS, label='Please select a string', required=True) chosen_number = forms.IntegerField(label='Please select an integer', widget=forms.NumberInput(attrs={'placeholder': 0})) Currently both fields appear on the form. My goal however is to show just the ChoiceField by default, but when the user selects an option different from the default "Select..." option, append the IntegerField to the form as well. I am aware of the .changed_data property and the .has_changed() method, but both of these seem to only activate upon a "submit" button press which is not what I intend. Ideally, I would like the IntegerField to immediately when the user changes the ChoiceField from the default "Select..." to anything else, e.g. "aa". How could I achieve this - if it is even possible? My views.py now only has the following: def form_interactivity(response): form = MyCustomForm(response.POST or None) # ? # print(form.changed_data, form.has_changed()) return render(response, "main/form_interactivity.html", {"form": form}) -

Display office files or pdf files using ViewerJS in a Django template
I'm trying to use ViewerJS in a Django 3.1 application in order to display office documents or pdf's within a Django template. The url I created is http://localhost:8000/static/js/ViewerJS/index.html/#..media/files/Materials.pdf This generates this: That is, it lifts the index.html file but no more than that. When I look at the developer console -> networks I see that many items of viewer js are not found, I understand that this is why the presentation fails. ViewerJS is located in static/js/ViewerJS In the template I have tried these two ways: <a href="/static/js/ViewerJS/media/archivos/Materiales.pdf" class="btn">Preview</a> <iframe src = "/static/js/ViewerJS/index.html/#../media/archivos/Materiales.pdf" width='700' height='550' allowfullscreen webkitallowfullscreen></iframe> If you know of another solution by which I can do what I need and it is not ViewerJs, it is welcome.

It can be achieved by overriding label_from_instance method ModelChoiceField as below: from django import forms from blog.models import Status, Article class StatusModelChoiceField(forms.ModelChoiceField): def label_from_instance(self, status): label = f"{status.order}: {status.name}" return label class ArticleForm(forms.ModelForm): status = StatusModelChoiceField(queryset = Status.objects.all()) class Meta: model = Article fields = ('headline', 'status') Problem with this method is that, it doesn't take into account Article model's status field definition. For example, although status field is nullable in Article model, it is required in ArticleForm. I should tell explicitly that it is not required (status = StatusModelChoiceField(queryset = Status.objects.all(), required=False)). If status field would have limit_choices_to, it also won't be considered in my form dynamically. So, I just want different display names than default __str__. How can I achieve this goal in more DRY manner? -
