SQL or django query to find the similar entries
I want to return the user a list of similar tasks. Two tasks A and B are considered similar if all the words in task A exist in task B or vice versa. I tried the query given below but couldn't get the required result. SELECT t1.task FROM todolistapp_todo t1 LEFT JOIN todolistapp_todo t2 ON t1.task in (t2.task) and t1.id != t2.id; I'm able to do this by the nested loop. But I want to do it by simple expression. similar = set() for task in tasks: for nested_task in tasks if (task.task in nested_task.task or nested_task.task in task.task) and task.id != nested_task.id: similar.add(task) -

How to setup Nginx server for angular and django
I'm trying to deploy a web application to my server. I have put the html files in one folder and I have a django server running on the same server.

How to show BinaryField image preview in Django admin interface?
I've got web project with Django backend for which I decided to store images as BinaryField, it seemed to be more convenient for me in case of making backups and restoring them. At first I've created model: class ThermalSource(ClusterUnit): ... scheme_image = models.BinaryField(verbose_name='Scheme', blank=True, null=True, editable=True) ... Then created serializer to use in viewset (I know it is not related to admin interface, but maybe it will be useful): class Base64BinaryField(serializers.Field): def to_representation(self, value): from base64 import b64encode return b64encode(value) def to_internal_value(self, data): from base64 import b64decode return b64decode(data) class ThermalSourceSerializer(APAMModelSerializer): ... scheme_image_base64 = Base64BinaryField(source='scheme_image') ... Now I could get and set images converted to Base64 correctly via Django REST Framework. Admin class for ThermalSource looks so now: class ThermalSourceForm(forms.ModelForm): scheme_image = forms.FileField(required=False) def save(self, commit=True): if self.cleaned_data.get('scheme_image') is not None \ and hasattr(self.cleaned_data['scheme_image'], 'file'): data = self.cleaned_data['scheme_image'].file.read() self.instance.scheme_image = data return self.instance def save_m2m(self): # FIXME: this function is required by ModelAdmin, otherwise save process will fail pass class ThermalSourceAdmin(admin.ModelAdmin): form = ThermalSourceForm readonly_fields = ('id', ) list_display = ('id', ... 'scheme_image') But when I open Django admin interface, I could only download files to scheme image field, no preview is configured. Could anybody suggest me how could I … -

How to derive an attribute from another in Django
Here is my first project in which I am experimenting with the Django documentation: a Person model. and two featured views (one to create a person and the other to view the list of created persons). So far a person has only two CharFields, first_name and last_name. What I'd like to do now is to implement a BooleanField adult, which returns True if the difference between today's date and the date of birth is greater than or equal to, say, 18 (or 16, it doesn't matter). Possibly I would also implement an attribute age based on the same principles. Obviously, it would be perfectly ok to derive adult from age. How can this be implemented in Django? Where should I write the piece of code that makes the math to derive adult/age? Inside models.py, forms.py, views.py or maybe inside the template? P.S. I know it looks weird to see the age attribute been declared as a DurationField, but as I was saying I am trying to experiment with different attribute fields. If the answer to my question requires it to be changed into, say, PositiveInteger, I don't mind changing it. My models.py looks like this from django.db import models # … -
modifying queryset in django admin page for auth_users and a custom related model
So, I have a model DailyTask that has a OneToOneField to the auth_users model, this is the DailyTask model fields : task_id task_date user ( OneToOneField ) Now each user has to submit a new Task report daily, already have an AdminModel that display all the submitted Tasks respectively to the logged in non superuser, here is the AdminModel : class DailyTaskAdmin(admin.ModelAdmin): def get_queryset(self, request): qs = super().get_queryset(request) if request.user.is_superuser: return qs return qs.filter(user=request.user) and I have created a proxy Model so I can create and register another AdminModel using the same Model : class MyDailyTask(DailyTask): class Meta: proxy = True then the second AdminModel : class DailyPresenceAdmin(DailyTaskAdmin): def get_queryset(self, request): qs = super().get_queryset(request) if request.user.is_superuser: return qs return qs.filter() admin.site.register(MyDailyTask, DailyPresenceAdmin) My only problem is, that in the DailyPresenceAdmin AdminModel, want to list all the users from auth_users that has not uploaded their Task of the day yet. so it will be something like, if auth_users.user has no TaskID with the date equals to today's date in the DailyTask Model yet, then I want to take the user and list it in the DailyPresenceAdmin AdminModel. -
Get data to Modal on button click, with buttons that have the same ID
Scenario - I have a page that has job listings, every individual job listing has a button called apply. A modal pops open when you click it, however that modal has no context as to which job the user wants to apply to, so I want to get the ID of the Job posting to the modal somehow. Problem - The buttons are being procedurally generated and have the same ID's. So using javascript to catch a onclick event cause for some reason it only gets the data-id of first button. {% for vacancy in vacancies %} <div class="card"> <div class="card-body"> <h5 class="card-title">Job Title - {{ vacancy.job_title }} </h5> <strong><p>Description </p></strong> <p class="card-text">{{ vacancy.job_description }}</p> </div> <button id="openmodal" data-id="{{ vacancy.id }}" type="button" class="btn btn-primary" data-toggle="modal" data-target="#myModal"> Apply </button> </div> {% endfor %} <div class="modal-body"> <form action="" class="customer-input" method="post" enctype="multipart/form-data"> {% csrf_token %} <div class="row"> <div class="form-group col-lg-6"> <label for="fullName">Full Name</label><br> <input name="full-name" type="text" placeholder="Full Name" required="required"> </div> <div class="form-group col-lg-6"> <label for="email">Email</label><br> <input type="email" name="email" placeholder="Email" required="required"> </div> </div> <div class="row"> <div class="col-lg-6"> <div class="form-group"> <label>Job Role</label><br> <select class="job-role" name="job-role"> <option value="python-developer">Python Developer</option> <option value="fullstack-developer">Full Stack Developer</option> </select> </div> </div> <div class="col-lg-6"> <div class="form-group"> <label>Your Resume</label><br> <input type="file" name="resume" accept=".pdf, … -

Django database post content as template
Hopefully, my title makes any sense. I'm building a personal blog with Django. I have some posts in my database and am trying to determine the best way to load images in my posts without specifying the entire path to my static directory. So, I pass my Post query into my template. In my template I have the following: <div class="post-content"> {{ post.post_content|safe }} </div> The post content loads but template tags such as static aren't loaded as expected. For example, my post_content might be: "A little text. And an image: <img src=\"{% static '/default-images/default-post-thumbnail.jpg' %}\" width='200'>" I'm using the django template tag static (which I did remember to load at the top of the template) in my img src but once the page is loaded the src for the image ends up looking like: src="{% static '/default-images/default-post-thumbnail.jpg' %}" Does anyone have recommendations for getting that static template tag to function as expected and fill in the img src with my STATIC_ROOT path? Let me know if you need further explanation or additional code and thanks in advance for any help! -

I'm using django internationalization. when I use simple strings, everything is fine and working as expected: translation.activate('en-us') translation.gettext('english string') # returns 'english string' translation.activate('fa-ir') translation.gettext('english string') # returns 'translated string' but when I use "named-string interpolation", it behaves strangely: class ConfirmationCodeForm(forms.Form): confirmation_code = forms.CharField( max_length=CODE_LENGTH, # translation for label works just fine, as expected. label=translation.gettext_lazy('Confirmation Code'), # translation for help_text behaves strangely. help_text=translation.gettext_lazy( 'Enter the %(number)s digit code that was sent to you.' ) % { 'number': CODE_LENGTH } ) form = ConfirmationCodeForm() field = form.fields['confirmation_code'] translation.activate('fa-ir') field.help_text # returns the translated string with no problem translation.activate('en-us') field.help_text # Again! returns the translated string instead of the English one That's really confusing. I don't know what I did wrong... If I remove translated string from .mo file, then it always returns the english string: #: forms.py:12 #, python-format msgid "Enter the %(number)s digit code that was sent to you." msgstr "" translation.activate('fa-ir') field.help_text # returns the english string as expected translation.activate('en-us') field.help_text # returns the english string as expected -
