How to Create Multiple Modal Dynamically in a Single Page
I am doing a Django Blog Project and it fetch all Blogs from the Database and show Blog Title in User Profile only. I want to create Bootstrap Modal for each Blog that is shown in the profile. Whenever a User click on a Title, the Modal will appear with Details. {% for blog in blogs.all %} <div class="card mb-4 shadow-sm "> <p class="card-text "><h2>{{ blog.title }}</h2></p> <div class="card-body"> <div class="btn-group"> <!-- Open a Modal for the blog --> <!-- Button To Implement the Modal--> <button id = "modalToggle" type="button" class="btn btn-sm btn-outline-secondary" data-toggle="modal" data-target="#modal">View More</button> <!-- Modal --> <div class="modal fade" id="modal" role="dialog"> <div class="modal-dialog modal-lg"> <div class="modal-content"> <div class="modal-header"> <h4 class="modal-title">{{ blog.title }}</h4> </div> <div class="modal-body"> <p>{{ blog.body }}</p> </div> <div class="modal-footer"> <button type="button" class="btn btn-default" data-dismiss="modal">Close</button> </div> </div> </div> </div> </div> </div> </div> Here all Blogs are showing the Modal of the first one. I cannot create multiple modals for each Blog. -
Django ModelChoiceField auto select views passed value
I have a simple problem with ModelChoiceField , I have a Classification class with four fields (name, price1, price2, price3) , I added an edit button and its working perfectly , i added the name on edit page as a ModelChoiceField , My problem is that am trying to force select the name value when edited so the user will only be able to change prices values . I read the doc about ModelForm which led me to this https://docs.djangoproject.com/en/2.2/ref/forms/api/#django.forms.Form.initial I tried initial= but it did not worked as i though it would. Any idea of either dynamically select the value or just print the name without allowing the user to change it would be great . here is my code , views.py def edit_class(request, name): classifications = Classification.objects.all() devices = Devices.objects.all() inst = Classification.objects.get(name=name) if request.method == 'POST': classification = EditClassForm(request.POST, instance=inst) if classification.is_valid(): classification.save() return redirect("/classifications.html") else: classification = EditClassForm() return render(request, 'classifications.html', {"form": classification, "classifications": classifications, "devices": devices}) forms.py class EditClassForm(forms.ModelForm): class Meta(object): model = Classification fields = ("name", "price1", "price2", "price3") def __init__(self, *args, **kwargs): super(EditClassForm, self).__init__(*args, **kwargs) self.fields['name'] = forms.ModelChoiceField(queryset=Classification.objects.all(), initial=0) self.fields['name'].widget.attrs.update({'class': "form-control"}) self.fields['price1'].widget.attrs.update({'class': "form-control", 'value': 0}) self.fields['price2'].widget.attrs.update({'class': "form-control", 'value': 0}) self.fields['price3'].widget.attrs.update({'class': "form-control", 'value': 0}) … -
Django Query Models Based Time and ForeignKey Value
I need help with querying Django objects. I have 3 models: Building, Map, and Report. A single building can have many maps. A single map can have many reports. Given the name of a building I would like to find the most recent report for each floor. That is, I want a list of Reports where each report has a different floor and each report is the most recent report for that floor. class Building(models.Model): building_id = models.AutoField('BID', auto_created=True, primary_key=True) name = models.CharField('Name', max_length=128) class Map(models.Model): map_id = models.AutoField('MID', auto_created=True, primary_key=True) building_id = models.ForeignKey(Building, on_delete=models.CASCADE, default=1) floor = models.CharField('Floor Number', max_length=128) class Report(models.Model): report_id = models.AutoField('RID', auto_created=True, primary_key=True) map_id = models.ForeignKey(Map, on_delete=models.CASCADE, default=1) building_id = models.ForeignKey(Building, on_delete=models.CASCADE, default=1) created_date = models.DateTimeField(auto_now_add=True) I have some pseudo-code below, but there must be an easier way using Django filters. Any ideas? name = "Mall" # All of the buildings reports reports = Reports.filter(building_id__name= name) floors_seen = [] latest_reports = [] for report in reports: floorNumber = report.map_id.floor_num if floorNumber not in floors_seen: floors_seen.append(floorNumber) latest_reports.append(report) else: for latest_report in latest_reports: if latest_report.map_id.floor_num == floorNumber: if report.created_date > latest_report.created_date: latest_reports.remove(latest_report) latest_reports.append(report) -
Direct assignment to the forward side of a many-to-many
I am trying to assign value to a ManyToManyField, however, any attempt I make to set a value on the db fails. Below is my simplified models.py class AppointmentRequest(models.Model): my_name = models.TextField(default='') requester_name = models.TextField(default='') meeting_date = models.TextField(default='') class CustomUser(AbstractUser): firstname = models.TextField(default='') appointments = models.ManyToManyField(AppointmentRequest) Below is the function in views.py that handles some functionality: from .models import AppointmentRequest def book_appointment(request, template_name) apt_request = AppointmentRequest() apt_request.requester_name = requesting_user apt_request.meeting_date = date apt_request.save() update_user.appointments = apt_request update_user.save() With the above I get the following error Direct assignment to the forward side of a many-to-many set is prohibited. Use appointments.set() instead. However, if I use set instead of =, I get the following error django manytomany 'str' object has no attribute 'set'. I am not sure what the problem is. Please help. -
Is it possible to create multiple model instances from a list of lists derived from another model?
I have two models, RecurringEvent and Event. The RecurringEvent models basic purpose is to create a list of datetimes, that is then to be used to create multiple events in the Event model. I have tried the save method with a for loop. However, no new Events are created, nor are any errors given. I’m not sure if its related to my loop (probably is). I’ve tried it a few different ways (using a list of named tuples, plain list of lists, rewriting the for loop in different ways) and have been unsuccessful. Is a model.manager needed to do this? I appreciate any help and would definitely like to know of any better ways to go about this. models.py class ReccuringEvent(models.Model): semester_start = models.DateField(null=True, blank=True) semester_end = models.DateField(null=True, blank=True) lesson_start = models.TimeField(null=True, blank=True) lesson_end = models.TimeField(null=True, blank=True) title = models.CharField(max_length=255, null=True, blank=True) … recurring_event_list = […] recurring_event_list_namedtuple = namedtuple('event', ['title', 'start', 'end']) recurring_event_list_named = [recurring_event_list_namedtuple(*d) for d in recurring_event_list] def save(self, *args, **kwargs): for d in range(len(recurring_event_list_named)): Event.objects.create(recurring_event_list_named) super().save(*args, **kwargs) # have tried including super(Event, self)… class Event(models.Model): title = models.CharField(max_length=200, null=True) description = models.TextField(max_length=255, null=True, blank=True) start = models.DateTimeField(null=True, blank=True) end = models.DateTimeField(null=True, blank=True) -
Python save/reload cache upon de-deployment
I have the following function in my django project which calls an external api with caching setup hourly as follows: @cached(cache=TTLCache(maxsize=1000, ttl=settings.CACHE_EXPIRATION_HOURLY)) def get_external_data(zip_code): my_url = MY_API.format(zip_code) my_response = requests.request( 'GET', url=my_url, headers={ 'zip-code': zip_code } ) return my_response As far as i know, local caches will likely be cleared when the web servers are re-deployed or when the runserver restarts. How do you prime or save/reload the cache to avoid a spike in backend traffic each deployment? -
Django: Clone instance, Multiple Model Forms
I would like to clone an instance of my object. I am aware of the solution to: obj = ProductModel.objects.get(pk=self.object.id) obj.pk = None as described in many references, such as Link However, I struggle to implement this solution when I need to refer to a super. How can I modify the object already at start so super refers to the modified obj.pk = None ? My View.py looks like below but the super refers to the original object and not the modified object: class ProductUpdateView(UpdateView): model = Product slug_field = 'product_uid' obj = Product.objects.get(pk=self.object.id) obj.pk = None def get_context_data(self, **kwargs): context = super(ProductUpdateView, self).get_context_data(**kwargs) context['form_1'] = ModelForm_1(instance=self.obj) context['form_2'] = ModelForm_2(instance=self.obj) return context def form_valid(self, form): self.object = form.save() return super().form_valid(form) def get_success_url(self): return reverse('product-list') -

How to convert form field data before saving to database in a Django ModelForm?
I'm creating an "edit" page in Django python framework (template 'edit_page.html') where user should be able to edit existing data stored in a database. For now I can easily retrieve existing raw data in user form (a Django template), my issue is that I need to convert data populated by user before saving the form. I have an 'ipv4' field in my model mapping a database table column with IPv4 addresses stored as unsigned int. For instance ip address '10.0.0.0' is stored as 167772160 in the database. Data conversion for 'ipv4' could be implemented as follows (exemple): # Convert from raw database to human friendly format (167772160 -> 10.0.0.0) import ipaddress ipv4_raw = 167772160 ipv4_friendly = str(ipaddress.ip_address(ipv4_raw)) print(ipv4_friendly) # Output: 10.0.0.0 # Convert from human friendly format to raw database format (10.0.0.0 -> 167772160 ) import ipaddress ipv4_friendly = '10.0.0.0' ipv4_raw = int(ipaddress.ip_address(ipv4_friendly)) print(ipv4_raw) # Output: 167772160 My form needs to show human friendly 'ipv4' to the user but must have the capability to update the database column in 'raw' format (int). 'ipv4' must be converted from raw format to user friendly format for display and the other way around for database update. Where should I perform this operation and … -
How to edit model objects in an inline formset in Django
In Django I am trying to use an inline formset factory so a user can edit instances of a model related to a parent model via a foreignkey. For some reason the methods I am trying don't save the changes I make when I click submit. My view is like this (not including render): def edit_sets(request, exercisegroup_id): exercisename = ExerciseName.objects.get(pk=exercisegroup_id) SetLoggerFormSet = inlineformset_factory(ExerciseName, SetLogger, fields=('weight','reps',)) formset = SetLoggerFormSet(instance=exercisename) if request.method == 'POST': formset = SetLoggerFormSet(request.POST, instance=exercisename) if formset.is_valid(): formset.save() else: formset = SetLoggerFormSet(instance=exercisename) and I am displaying each form in the formset in my template so the user can individually edit the instance: <form method="post">{% csrf_token %} {{ formset.management_form}} <table> {% for form in formset %} {{ form }} {% endfor %} </table> <button type="submit" class="save btn btn-default">Save set</button> </form> Stuck as to why this isn't working. The form displays as it should and this method has previously worked for adding objects, but I am still unable to use it to replace one of those objects in the queryset. Am I missing something I should be doing differently? -

Django ignore_conflicts doesn't work for User model
I am trying to create a lot of users for testing my Django application. I've used this method on other models and it works, but here it doesn't. When executed it states the error below. The latest Django version (2.2.6) was used. The documentation states: (...) setting the ignore_conflicts parameter to True tells the database to ignore failure to insert any rows that fail constraints such as duplicate unique values. My Code: def draftUser(i): return User(username='Testguy' + str(i), first_name=randomString(7), last_name=randomString(5)) user_cache = [] for i in range(1, 10000): user_cache(draftUser(i)) User.objects.bulk_create(user_cache, ignore_conflicts=True) The last line of the error code: django.db.utils.IntegrityError: UNIQUE constraint failed: auth_user.username
