Django, render a model in template
How can I render a model from a template? Lets say I have: class A(models.Model): title = models.CharField() class B(models.Model): a = models.ForeignKey(A, on_delete=models.CASCADE) class C(B): text = models.TextField() integer = models.IntegerField() class D(B): image = models.ImageField() comment = models.CharField(max_length=300) Current template for A: <h1> {{ a.title }}</h1> <div> {% for b in a.b_set.all %} <!-- What do I put here? --> {% endfor %} </div> In the template for A I would like to render all instances of C and D, but since they have different fields their HTML will have to be different. How do I specify how each model should be rendered? Do I need to create a special method in the models? -
NoReverseMatch - Reverse for 'step-autocomplete' with arguments '()' and keyword arguments '{}' not found. 0 pattern(s) tried: []
First of all I realize this question has been asked several times prior, but I've looked at several solutions and have been unable to fix my issue. Furthermore, I have tried several things that have worked for me before when I've had this error, including using various 'return redirect/reverse/httpresponse' with arguments, and these haven't worked either. I'm following this tutorial https://github.com/yourlabs/django-autocomplete-light/blob/master/docs/tutorial.rst#id5 to create autocomplete fields, and in the second stage where I go into the shell and check if the url can be reversed I get the NoReverseMatch error. My view and url are below. View: class StepAutoComplete(autocomplete.Select2QuerySetView): def get_queryset(self): # Don't forget to filter out results depending on the visitor ! if not self.request.user.is_authenticated(): return Step.objects.none() qs = Step.objects.all() if self.q: qs = qs.filter(name__istartswith=self.q) return qs form: url(r'^step-autocomplete/$', StepAutoComplete.as_view(), name='step-autocomplete'), traceback: File "<console>", line 1, in <module> File "/Library/Python/2.7/site-packages/django/core/urlresolvers.py", line 600, in reverse return force_text(iri_to_uri(resolver._reverse_with_prefix(view, prefix, *args, **kwargs))) File "/Library/Python/2.7/site-packages/django/core/urlresolvers.py", line 508, in _reverse_with_prefix (lookup_view_s, args, kwargs, len(patterns), patterns)) NoReverseMatch: Reverse for 'step-autocomplete' with arguments '()' and keyword arguments '{}' not found. 0 pattern(s) tried: [] -
csrf token missing in django ajax post request working using get request
I am working with metronic datatables in which i have a file where ajax function works.

ModelForm won't validate because missing value, but model field has null=True
I have a problem where my ModelForm is trying to assign '' to a field (it saves fine if I actually provide the primary key of the Product, but it's not a compulsory field, and won't save if the field is left blank). I take it that the ORM it's trying to set that field to ''but: Shouldn't '' be coerced to None, and; Why isn't the model form trying to set that field to None in the first place instead of ''? models.py class Question(models.model): fk_product = models.ForeignKey(Product, on_delete=models.SET_NULL, null=True, related_name="product_question") forms.py class QuestionForm(forms.ModelForm): fk_product=forms.ChoiceField(required=False) class Meta: model = Question fields = ['fk_product',] The error: Cannot assign "''": "Question.fk_product" must be a "Product" instance.

Django Rest Framework ManyToMany Filter
I have two models, one defining users, the other defining labels on these users. I am using Django Rest Framework to create an API. I would like to be able to query users for with labels ids 1 and 2. So far, I've managed to query users with a given label (let's say id=1) by doing: /api/users/?labels=1, but I am unable to query users with labels 1 and 2. I've tried /api/users/?labels=1,2 or /api/users/?labels=1&labels=2 but it return some invalid users, i.e. users without labels 1 or 2... Any help is welcome. Thanks, Dimitry Here is my code: models.py class Label(models.Model): name = models.CharField(max_length = 60) class User(models.Model): labels = models.ManyToManyField(Label) filters.py class UserFilter(django_filters.FilterSet): labels = django_filters.filters.BaseInFilter( name='labels', lookup_type='in', ) class Meta: model = User fields = ('labels',) serializers.py class LabelSerializer(serializers.ModelSerializer): class Meta: model = Label fields = ('id','name') class UserSerializer(serializers.ModelSerializer): labels = LabelSerializer(many = True) class Meta: model = User fields = ('labels',) filter_class = UserFilter views.py class UserViewSet(viewsets.ModelViewSet): queryset = User.objects.all() serializer_class = UserSerializer filter_backends = (filters.DjangoFilterBackend,) filter_class = UserFilter filter_fields = ('labels',) -
Django 1.95 template i18n not working
I am trying to translate the string from English to zh-hans In the settings.py LANGUAGE_CODE = 'zh-hans' TIME_ZONE = 'UTC' USE_I18N = True USE_L10N = True USE_TZ = True I have run the python manage.py makemessages -l zh-hans and python manage.py makemessages -a for many times. The .po file is simple as following: msgid "" msgstr "" "Project-Id-Version: PACKAGE VERSION\n" "Report-Msgid-Bugs-To: \n" "POT-Creation-Date: 2016-09-07 09:53+0000\n" "PO-Revision-Date: YEAR-MO-DA HO:MI+ZONE\n" "Last-Translator: FULL NAME <EMAIL@ADDRESS>\n" "Language-Team: LANGUAGE <LL@li.org>\n" "Language: \n" "MIME-Version: 1.0\n" "Content-Type: text/plain; charset=UTF-8\n" "Content-Transfer-Encoding: 8bit\n" #: blog/views.py:18 msgid "author" msgstr "作者" In the html file: <div id = "info"> <p> {% trans "author" %} : {{ blog.author }} </p> </div> The tag returns "author" instead of Chinese characters. Also I have tried ugettext in view.py def detail(request, slug): blog = get_object_or_404(Post, slug=slug) msg = _("author") print(msg) context = { 'blog': blog, 'author': msg, } return render(request, 'blog/detail.html', context) The msg is still "author". Using {% get_current_language as LANGUAGE_CODE %} {{ LANGUAGE_CODE }} The language code is zh-hans. So what's going wrong here? How to show the translated string in the template? Thank you -
Using named arguments as variables
I am using django but I think this question primarily belongs to Python itself. I have something like: def get(self, request, arg, *args, **kwargs): if kwargs['m0'] == 'death': if kwargs['m1'] == 'year': result = Artists.objects.filter(death_year=arg) elif kwargs['m1'] == 'month': result = Artists.objects.filter(death_month=arg) elif kwargs['m1'] == 'day': result = Artists.objects.filter(death_day=arg) elif kwargs['m0'] == 'birth': if kwargs['m1'] == 'year': result = Artists.objects.filter(birth_year=arg) elif kwargs['m1'] == 'month': result = Artists.objects.filter(birth_month=arg) elif kwargs['m1'] == 'day': result = Artists.objects.filter(birthh_day=arg) Where death_year is a named argument that is a field in my model Artists representing a column in my database. The variables 'm0' and m1 are passed from the urlconf to my get function (it is actually a get method in my view class). Can I control the name value of the variable death_year without using an if else if chain (i.e. make it death_month or birth_year)? Since I have many choices, I will have to use a ridiculously very long conditional chain that leads to this same line but with just a different named argument. I strongly doubt that you should understand this whole problem to answer the question. The original question is simple: Can I use a named argument and its corresponding value as … -
Django form and many2many.through field
I'm building a wizard (using Django Formtools) that would allow one to order one or several items, with the possibility for each selected item to specify the quantity desired. I'd like to avoid the classical cart system and make the purchase as simple as possible. My navigation proposal is to have only 3 pages/steps: the first page show a form with all the available items. those items can be selected and visitors can specify a quantity. the second page makes a summary of the order and visitors are asked to fill their details the last page confirms the order I'm having troubles creating the form for the first step and I'm looking for help to find a middleground between the two options I tried. My Django models look like this (simplified for the demonstration): class Item(models.Model): name = models.CharField(max_length=255) price = models.DecimalField(max_digits=5, decimal_places=2) class Order(TransactionBase): items = models.ManyToManyField(Item, through='OrderedItem') class OrderedItem(models.Model): order = models.ForeignKey(Order) item = models.ForeignKey(Item) quantity = models.PositiveSmallIntegerField() Using the following ModelForm I'm able to list all the available Items: class OrderSelectionForm(forms.ModelForm): class Meta: model = Order fields = ('items',) widgets = { 'items': forms.CheckboxSelectMultiple(), } But it doesn't allow for specifing the quantity... Using the following code, … -
Use django models objects in AngularJs javascript file
How can I use my django Models objects in a AngularJS javascript file? I think I did al the necessary things but still can't use them in my angularjs file.

How to localize date in Jinja2 + Django?

django inspectdb 'unique_together' refers to the non-existent field
I have a legacy database that I wish to use as a second database in my django project. I added the database to my settings file, and ran: python manage.py inspectdb --database=images The script finished in less than a second, and the results were astounding. It understood all my tables - or so I thought at first. When I tried to run: python manage.py migrate --database=images I got errors like this: 'unique_together' refers to the non-existent field 'commentaryId'. All of the tables that raised errors were many-to-many linking tables containing two id fields that together formed the primary key (and thus had to be 'unique together'). Here is one of the models, created by inspectdb, that raised this error: class Pagescanannotationscommentaries(models.Model): pagescanannotationid = models.IntegerField(db_column='pageScanAnnotationId') # Field name made lowercase. commentaryid = models.IntegerField(db_column='commentaryId') # Field name made lowercase. class Meta: managed = False db_table = 'PageScanAnnotationsCommentaries' unique_together = (('pageScanAnnotationId', 'commentaryId'),) I found several questions like mine in stackoverflow, but the suggestions did not help me, or were obviously not relevant. But I did find a post in google groups that gave me the tip that fixed it: https://groups.google.com/forum/#!topic/django-users/_phTiifN3K0 But even then, my problem was a bit different, I found, and I … -

javascript event handler not correctly work in django inline formset
I designed a inline formset as follows: class EventForm(ModelForm): class Meta: model = Event exclude = ['created'] class GalleryForm(ModelForm): class Meta: model= Gallery exclude = ['pub_date'] GalleryFormSet = inlineformset_factory(Event, Gallery, extra=0, min_num=1, fields=('title','image' )) It worked correctly when used 'extra = some number' and saved gallery form data correctly. But when I used javascript handler to add additional gallery form below the main Event form, it creates two Gallery form instead of 1 and data and photo not saved from the newly added form.

JS/Jquery issue when deploying Django site on with Gunicorn/Nginx (on DigitalOcean)
TL;DR. Main question at the bottom. I've made a django website and wanted to dynamically make an image fill in a div tag. Here's the JS/JQuery function I wrote: function changeBGSize(){ $(document).ready(function(){ var posX = -1 * (($("#myPic").width())/2); var posY = -1 * ($("#myPic").height() - $(window).outerHeight())/2; $("#myPic").css("margin-left", (posX + "px")); $("#myPic").css("margin-top", (posY + "px")); }) } Inside the HTML I have an image with the ID myPic nested in divs. It might be useful to add that I'm also using Bootstrap v3. I call the above function in 2 ways: window.onload = changeBGSize; in the main JS <body onresize="changeBGSize();"> in the HTML WHen I deploy the website on local host using python manage.py runserver the website works fine and the picture is centered as I want it. But the problem is when I deploy it to my DigitalOcean droplet. My droplet is a linux ubuntu 14 machine, and uses Gunicorn and Nginx to serve static files. For some reason the JQuery function above does not work when the screen is loaded, but it works when called through the onresize event. After debugging I've come to realize that $("#myPic").height() gives the wrong value when first called. In fact its value is … -

Here is the code for setting up the Product set product_set = ProductSet(None, <CATALOG ID>) # <CATALOG ID> product_set[ProductSet.Field.name] = 'Product Set' product_set[ProductSet.Field.filter] = { 'product_type': { 'i_contains': 'example product type', }, } product_set.remote_create() product_set_id = product_set[ProductSet.Field.id] And Code for creating AD after setting campaign and adset : adset = AdSet(parent_id='<ACCOUNT_ID>') adset[AdSet.Field.name] = 'Product Adset' adset[AdSet.Field.bid_amount] = 9100 adset[AdSet.Field.billing_event] = AdSet.BillingEvent.link_clicks adset[AdSet.Field.optimization_goal] = AdSet.OptimizationGoal.link_clicks adset[AdSet.Field.daily_budget] = 45500 adset[AdSet.Field.campaign_id] = campaign_id adset[AdSet.Field.targeting] = { Targeting.Field.publisher_platforms: ['facebook', 'audience_network'], Targeting.Field.device_platforms: ['desktop','mobile'], Targeting.Field.geo_locations: { Targeting.Field.countries: ['IN'], }, Targeting.Field.product_audience_specs: [ { 'product_set_id': product_set_id, 'inclusions': [ { 'retention_seconds': 2592000, 'rule': { 'event': { 'eq': 'ViewContent', }, }, }, ], 'exclusions': [ { 'retention_seconds': 259200, 'rule': { 'event': { 'eq': 'Purchase', }, }, }, ], }, ], Targeting.Field.excluded_product_audience_specs: [ { 'product_set_id': product_set_id, 'inclusions': [ { 'retention_seconds': 259200, 'rule': { 'event': { 'eq': 'ViewContent', }, }, }, ], }, ], } adset[AdSet.Field.promoted_object] = { 'product_set_id': product_set_id, } adset.remote_create() adset_id = adset[AdSet.Field.id]
