Stop executing if it is the case
$('.btn-process-request', node).bind('click', function(e){ e.preventDefault(); var data = {}; var fax_number_empty = {{ contract.request.customer.fax }} if (fax_number_empty == 0) { alert('Please, attach the fax number to your profile'); } alert('Hello!

I'd like say, ok, if contract.request.customer.fax is empty, then display an alert which will say 'Please, attach the fax number to your profile.' The most important thing here is to stop executing. In other words, what is bellow those lines would not be executed. Could anyone have time to tell me how to improve that code? P.S. Please don't be shy … -

Prefetch related after many-to-one relation
I have the following (simplified) model structure: class Article(Model): @property def article_number(self) -> str: return self.attributes.get(masterdata_type__code='article_number').value class Attribute(Model): article = ForeignKey(Article, null=True, blank=True, related_name='attributes') masterdata_type = ForeignKey(Type, related_name='attributes') value = CharField(max_length=256, blank=True, db_index=True) class Type(Model): code = models.CharField(max_length=32) In the admin panel, I want to show a list of 100s of articles and show its article_number. This now result in 100s of database calls (which I can see using Silk monitoring), so I want to prefetch those objects. I tried the following solutions in the admin panel, but all didn't work. What is the proper way to reduce number of database calls here? I am using Django 1.8.14, with a PostgreSQL backend. Solutions that don't work: def get_queryset(self, request): queryset = super(ArticleSetAdmin, self).get_queryset(request) return queryset.prefetch_related('attributes__masterdata_type') Still 100s of database calls. def get_queryset(self, request): queryset = super(ArticleSetAdmin, self).get_queryset(request) return queryset.prefetch_related( Prefetch('attributes', queryset=Attribute.objects.select_related('masterdata_type'))) Still 100s of database calls. def get_queryset(self, request): queryset = super(ArticleSetAdmin, self).get_queryset(request) return queryset.prefetch_related( Prefetch('attributes', queryset=Attribute.objects.prefetch_related('masterdata_type'))) Still 100s of database calls. def get_queryset(self, request): queryset = super(ArticleSetAdmin, self).get_queryset(request) return queryset.select_related('attributes__masterdata_type') Error, since attributes is Many-to-One relationship to Article. -

Bootstrap CSS - Info Box Alignment
I have the following bootstrap info box: <div class="alert alert-info" style="text-align: center" role="info"> <span style="font-size: 30px; vertical-align: middle; padding:0px 10px 0px 0px;" class="glyphicon glyphicon-info-sign alert-info" aria-hidden="true"></span> <span style="font-size: 13px; vertical-align: middle;" class="alert-info" role="info">Please help support your chosen charity <b>{{ request.session.chosenCharity }}</b> and the str8RED development by signing up for additional benefits.</span> </div> This creates the following box: As you can see it looks a little clumsy. I would like the "i" in the circle to be vertically centred in the blue box with the writing to its right but NOT over lapping like it currently does. I have tried using the django grid but it made the "i" and the writing look too far apart. I tried to use HTML tables but could not get it to match what I am after. Any thoughts on how to solve this would be greatly appreciated. -

Unicode decode error in Django Report Builder
So I am in the process of standing up a Django site that connects to four legacy DBs. From the admin panel in django everything works correctly. I am able to grab all the data. With the Report Builder GUI I can get most of them. But the most important one comes back with an error 500. It says that there is a unicode error at byte... Somewhere along the way it is unable to make the translation. I see a lot of people here with this problem but no real solutions for it. Where would I even begin to fix this??? -
Django language change after post request
I have this view in django which fetches post data from the form in another previous view. def sitexam(request): if request.POST: e_code = int(request.POST['engagement_code']) e_id = int(request.POST['exam_id']) return render(request, 'main/sitexam.html', {'title': 'SIT EXAM', 'qna': [e_code, e_id]}) Django translation is enabled and while testing on the sitexam view, it is POST request on the first time and if language is changed on the page it makes a GET request and can't access the context (qna) that I want in the template. How do I make the post data stay on language change on this view ? should I go for sessions or is there a better way to handle this situation ? -
How to edit Django FieldFile with S3 storage backend

Django query an unknown number of multiple date ranges
I have a form which allows a user to select users by multiple age ranges: 18-24, 25-34, 35-44 etc. Currently if a user selects the first two fields in the multiple selection list, the query will return users 18 - 34. If a user selects 18 - 24 year olds, and 35-44 year olds, it will include all ages from 18 - 44, when it should not include users aged 25-34. How would you approach including multiple range filters on a query without knowing the number of ranges you need to filter by prior to the users form selections? If you knew the number of age ranges the user was going to filter by I know you could chain range queries using Q. This is my current query: query = User.objects.filter( gender__in=genders, created__in=dates, data_source__in=sources, dob__range=[from, to] ) Thanks in advance. -

Passing kwarg to view from form
Trying to change two similar function views into one which can take extra kwarg. The view should show extra tags when i use my form. As far as the query for the active post works, the form gives back the same result completely ignoring what i write into form.

How can I filter by date to get this week vs previous week Counts from a QuerySet?
I have the following two annotated QuerySets which I have generated separately by extracting this_wk and prev_wk from a data set, then performing the annotation. I would like to merge them together before returning them. data = { 'this_wk': QuerySet([{'this_total': 3, 'dept': 2}, {'this_total': 2, 'dept': 1}, {'this_total': 1, 'dept': 3}]), 'prev_wk': QuerySet([{'prev_total': 2, 'dept': 3}])} Expected: QuerySet([{'this_total': 3, 'prev_total': None, 'dept': 2}, {'this_total': 2, 'prev_total': None, 'dept': 1}, {'this_total': 1, 'prev_total': 2, 'dept': 3}]), Alternatively, is there a way of aggregating this directly so that I go straight from a set of items with date fields? Here's how I am currently generating the two QuerySets: previous_items = Widget.objects.filter(start__gte=prev_start).filter(start__lte=prev_end) prev_ranking = previous_items.values('dept').annotate(prev_total=Count('dept')) this_items = Widget.objects.filter(start__gte=this_start ).filter(start__lte=this_end) this_ranking = this_items.values('dept' ).annotate(this_total=Count('dept') ).order_by('-this_total') Is there a way to chain these two annotations together so that I end up with a single QuerySet grouped and ranked for each Dept depending on how many Widgets it was used by this week, but also with an added field that says how many Widgets it was used by the previous week? I'm thinking something like this: items = Widget.objects.filter(start__gte=prev_start ).filter(start__lte=this_end ).annotate(prev_total=Count('dept') # can I restrict this to the previous week? ).annotate(this_total=Count('dept') # can I restrict this … -
How to change static and media directory for Django project that have 2 apps
This is a continuation for my previous question How to get hostname or IP in settings.py so that i can use it to decide which app's urls to use I am making a django application where it will have 2 apps.

How do i achieve what i wanted? thanks class SimpleMiddleware(object): def __init__(self, get_response): self.get_response = get_response # One-time configuration and initialization. def __call__(self, request): … -

Handle a click event in django-tables2
I am starting to use django-tables2 and I have added a column which should allow user to delete a record when the user clicks on the button. The code looks as follows: class ReviewTable(tables.Table): delete = tables.LinkColumn('review_delete', args=[tables.A('pk')], orderable=False, empty_values=(), verbose_name='') def render_delete(self, record): url = static('remove.png') href = '#' return mark_safe('<a href="' + href + '" Delete><img src="' + url + '"></a>') This basically enders the image fine in a column but all I can do is set the link to it. How can I get it to call some method where I can then filter by the record ID and delete the relevant record? Is this the correct way to do this? -
Should I iterate on django query set or over the variable?
I have a large dataset returned from django queryset and I want to iterate over it. Should I directly iterate over the queryset or store the results in a variable and iterate over it? for item in Model.objects.all(): do_something() or results = item in Model.objects.all(): for item in results: do_something() As far as I know, the variables are stored in heap and its safer, where as in case of iterating over queryset, the results will be stored in main memory. So which one is efficient in space and speed? -
