Django model TextField display zip code format
In my models.py, I have a zip code field that are in TextField format: class Merged(models.Model): zip_code = models.TextField(db_column='Zip Code', blank=True, null=True) However, there are some invalid zip codes like sagaponack 11962 lindenhurst 11757 I just want to display the 5-digit zip code without any other texts. What I have tried and failed In serializers.py, I tried to apply a RegexField to the zip_code column: class MergedSerializer(serializers.HyperlinkedModelSerializer): zip_code = serializers.RegexField(regex=r'^\d{5}') class Meta: model = Merged fields = '__all__' It did not work. How do I solve this in a way that does not only change how it displays, but also ensures that sorting works properly (i.e. ignore the text part, only sort based on zip codes) -

Django and chart.js - one bar per 'date' in model
I have a model that contains a date and a number. There are multiple inputs from the same date that I want to merge into 1 bar on the chart. How can I show each date only once but add up all of the totalPacks under that date? model: Views: def homepage(request): labels = [] data = [] queryset = DailyCountsModel.objects.order_by('-date') for jobs in queryset: labels.append(jobs.date) data.append(jobs.totalPacks) return render(request,'index.html', { 'labels': labels, 'data': data, }) Currently this chart will show one bar per entry.. I can't think of how I could do this. Any ideas? I'm guessing somehow I would need to check to see how many items they are with the 'date' of 2021-08-23 and add up the 'totalPacks', I'm just not sure how I would do this -
CPanel Slug in Django

How can I avoid infinite loop when reformatting url hash with Jquery event 'hashchange'
Issue Background I have set up my webpage to use identifiers with prefix #s- to differentiate anchor links from other page identifiers. The window.location.hash changes to hash which moves the frame to the content in focus but also triggers the hashchange listener causing a loop. What I've tried I have it working for whenever the hash has changed but the only instance it does not work is when the same link it pressed (as I use this in the condition to stop the infinite loop). The code for this was: $(window).on('hashchange', function(e) { if ($(location).attr('hash') != last_hash) { manageHash() } }); What I want I'd like to be about to find a condition or method to allow users to select a link to change the hash but also allow them to re-select the same link as many times as they want without causing a loop. JS last_hash = '' function manageHash() { var hash = $(location).attr('hash'); if($('#s-'+hash.substring(1)) != 0 && '#s-'+hash.substring(1) != '#s-' ) { last_hash = hash window.location.hash = '#s-'+hash.substring(1); } } $(window).on('hashchange', function(e) { if ($(location).attr('hash') != last_hash) { manageHash() } }); $(document).ready(function() { manageHash() }) HTML <div class="contentSubSectionContainer contentSubSection" id="s-{{ subsection.slug }}"> <h2 class="contentSubSectionFont1Bold">{{ subsection.sub_section_title }}:</h2> <div … -

Django form choicefield doesn't rendering empty field
I have a form that has a choicefield, choice as follow - TYPE = (('','Select type'), ('college', 'College'), ('university', 'University')) class Form(ModelForm): type = forms.ChoiceField(choices=TYPE) As the document says `` Unless blank=False is set on the field along with a default then a label containing "---------" will be rendered with the select box. To override this behavior, add a tuple to choices containing None; e.g. (None, 'Your String For Display'). Alternatively, you can use an empty string instead of None where this makes sense - such as on a CharField.``` I tried usign '' & None, both doesnt work ! It just shows the 'Select type' and immediately disappears ! Please help -
Django how to make timezone aware CustomTimeField?

Hide all records in Django admin unless a search query is entered
We have a Python-2.7 and Django project (version 1.11) that has lots of models registered on it (Users app, Invitations app, Profiles app, etc...) First thing I'm trying to do is create a group for some users that will have only viewing permissions when they log on to the Django admin and see limited models from the entire list. Second thing is to not have any records shown by default when you enter one of the models you're allowed to view. You must search for something in order for matching records to appear so that only results associated with that user is shown. Is this possible and if yes, how do I implement this? -

Django : Error: 'duplicate key value violates unique constraint'
I have to save images with s3 when creating a new object for my website. I have a code to save my images that I use in my model's save method. When I use the django administration panel, I can easily create my object without any error. But when I try to create my object throught my view, I get this error : Error: 'duplicate key value violates unique constraint « store_shop_pkey »' I think that in my serializer's create method, I try to save my object twice : once for the image and once for the rest of my object's keys.
