Display keys and values in template
I'm trying to display my dict values in my template, but I cannot properly handle one of the values. I'm not sure if it's the js file, the way I save the json or the template that's wrong. My template. {% for key1, values1 in products.products.items %} <div onClick="hello(this.id)" id="{{key1}}"> {{ values1 }} <----- Shows (1) {{ values1.pk }} <---- No show {% for key2, values2 in values1.items %} {{ values2 }} <---- No show {% endfor %} </div> {% endfor %} My view function. def createItem(request): form = itemCreateForm(request.POST) if form.is_valid(): model_instance = form.save(commit=False) model_instance.save() with open(BASE_DIR + '/kar/products.js', 'r+') as json_file: products = json.loads(json_file.read()) <--- Getting current values of json data = serializers.serialize('json', [model_instance,]) <-- Form to model instance struct = json.loads(data) data = json.dumps(struct[0]) products['products'][model_instance.pk] = data <--- updating current values print(products) json_file.seek(0) json_file.write(json.dumps(products)) <--- saving the updated values else: print('False') return HttpResponseRedirect('/homepage/CMS/') My products.js file {"products": { "102": "{\"pk\": 102, \"fields\": {\"price\": 31, \"name\": \"31\", \"type\": \"2\"}, \"model\": \"kar.item\"}", "103": "{\"pk\": 103, \"fields\": {\"price\": 22, \"name\": \"22\", \"type\": \"2\"}, \"model\": \"kar.item\"}" } } Running the above code will only display (1): {"pk": 103, "fields": {"price": 22, "name": "22", "type": "2"}, "model": "kar.item"} {"pk": 102, "fields": {"price": … -
For loop loops only once if there is function inside
I encountered a problem with my for loop. When there is function inside it loops only once, for the first item and this is it. If I comment-out the function it loops through all the items. This is the loop: for dev in devices: print(dev.device_id) emailNotification("[eTaborniki]: Novo sporočilo", str("Zadeva: "+msgsubject+"\r\n"+body_preview), str(dev.device_id)) And this is the function: def emailNotification(title, body, to): payload = { "to": to, "data": { "message": body, "title": title, "click_action": "https://****/sporocila", "icon": "https://****/images/logo-256.png" }, "from": FCM_ID } headers = { 'Content-Type': 'application/json', 'Authorization': FCM_KEY_HEADER, } r = requests.post('https://fcm.googleapis.com/fcm/send', data=json.dumps(payload), headers=headers) response = r.json() print(response) if response['results']['error'] is 'NotRegistered': token = PushDevices.objects.all().filter(device_id=to) token.delete() print("Token Deleted") -
How to override Django's User to return get_full_name() across project without extending User model
I want to overide the default return value of the Django User model to return get_full_name() instead of the default get_username(). That is the ONLY change I want to make to the model, and I don't want to create a custom User, as I already have a Profile model. The suggestion from this question looks like it would do it: from django.contrib.auth.models import User def get_first_name(self): return self.get_full_name() User.add_to_class("__str__", get_full_name) How can I put this, or something better, in settings.py to override this for my entire project? -

How to store a string that points to a boolean value in a django sqlite database
What I want to happen: I'm building a PTO(paid time off) App in django. I want the user to be able to choose between 4-5 different leave types such as "Jusry Duty", "Voting", "Emergency", etc etc and I want those strings to point to a True or False value that will determine whether or not the leave type is chargeable against the user's total PTO hours. The problem: The correct True or False value is saved to the database but when I view the record from within the django admin, if it is a True value it ALWAYS shows up as "PTO" and if it is a False value it ALWAYS shows up as "Jury Duty". I believe the reason it behaves like this is because "PTO" is the first True value in the tuple and "Jury Duty" is the first False value in the tuple. What I've tried: What I have right now is a boolean field on my PtoHistory model that takes in a tuple of LEAVE_CHOICES. class PtoHistory(models.Model): LEAVE_CHOICES = ( (True, 'PTO'), #is chargeable? (False, 'Jury Duty'), #is chargeable? (False, 'Voting'), #is chargeable? (False, 'Military Leave'), #is chargeable? (False, 'Bereavement'), #is chargeable? (True, 'Emergency'), #is chargeable? … -
Mapping JSON object with lodash
I'm trying to map a JSON object using lodash. I'm calling the json object as follows: var json = (function() { var json = null; $.ajax({ 'async': false, 'global': false, 'url': "{% url 'api_temp_income_statement' asset_details.id %}", 'datatype': "json", 'success': function (data) { json = data; } }); return json; }) Which returns a JSON object that looks like this: [{"model": "tempincomestatement", "pk": 3, "fields": {"income_period": "2016-01-31", "lease_income_collected": "994174.0000", "storage_income_collected": "236216.0000", "tax_income_collected": "131020.0000", "other_income_collected": "0.0000"} },... ] I'm trying to create a map that has an Income Period : remaining fields relationship, so "2016-01-31" : {"lease_income_collected" : "994174", ... } Reading the docs, it doesn't really address how to go about this...How would I accomplish this? -
GeoDjango OSMGeoAdmin cannot create new polygon in admin interface
I am using OSMGeoAdmin with a PolygonField. If one of my PolygonFields is null, the map shows up in the admin interface, but I cannot draw a new region.

I am able to edit an existing region: But the tool does not seem to work on an empty polygon. -
How to change a language's label in Django language specific URLs using i18n_patterns?
I'm using Django's i18n_patterns, so my URLs look like www.domain.com/pt/title. I want to change the language code in the URL to a different string, say, for example 'br' instead of 'pt', so the same url above would be rendered www.domain.com/br/title. I only want to change the language's label, not the actual translation. -

Django Template Remainder Error

In Django how can I run the same function from views multiple times without refreshing the page?
On one of my pages in my web app, I want to be able to view the disk space left on the server & I want that information to update every 30 seconds they are on the page. So far I was able to create a button that runs the function and displays the results, however, I have been unsuccessful in finding a way to call that function automatically. I have tried 'sched' with no luck and when I tried using a loop, it just slowed down my server. Any feedback or advice would be greatly appreciated! Thanks -

Django admin and autocomplete-light - how to override save method
I'm trying to include Django-autocomplete-light in my project. Everything works as expected including the creation of new choice by autocomplete. The only problem is my model contains more than one field and I'm using autocomplete only on the 'name' field. When I save my new record django-admin creates new object with the same name in the database instead of updating the record already created by autocomplete. At the end I have two records, one half empty created by autocomplete, and one valid created by django-admin. models.py class Montinent(models.Model): name = models.CharField(max_length=250) code = models.CharField(max_length=2, unique=True, db_index=True) created = models.DateTimeField(auto_now_add=True) class Meta: ordering = ('-name',) def __str__(self): return self.name views.py class MontinentAutocomplete(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 Montinent.objects.none() qs = Montinent.objects.all() if self.q: qs = qs.filter(name__istartswith=self.q) return qs urls.py urlpatterns = [ url(r'^admin/', include(admin.site.urls)), url(r'^montinent-autocomplete/$', MontinentAutocomplete.as_view(create_field='name'), name='montinent-autocomplete',), ] admin.py class MontinentForm(forms.ModelForm): name = forms.ModelChoiceField( queryset = Montinent.objects.all(), widget = autocomplete.ModelSelect2(url='montinent-autocomplete') ) class Meta: model = Montinent fields = ['name', 'slug', 'code'] class MontinentAdmin(admin.ModelAdmin): form = MontinentForm admin.site.register(Montinent, MontinentAdmin) The way autocomplete creates new choice is as follow: When the user selects that option, the autocomplete script will make a … -

How to upload image to custom location using models.ImageField and attribute?
I am an absolute beginner with Django so here is my question: I created a model and I have image = models.ImageField(). When I use the admin interface, every uploaded image is placed in the root directory. I read through this https://docs.djangoproject.com/en/dev/topics/files/ and if I use the below example it still doesn't work. from django.core.files.storage import FileSystemStorage fs = FileSystemStorage(location='/static/images/gallery') class Car(models.Model): ... photo = models.ImageField(storage=fs) The new entry is correctly added but when I click the image name, the following error is displayed, and the image is not placed in /static/images/gallery Page not found (404) Request Method: GET Request URL: http://127.0.0.1:8000/admin/Library/book/12/change/002_user_experience_remastered.jpg/change/ Raised by: django.contrib.admin.options.change_view book object with primary key '12/change/002_user_experience_remastered.jpg' does not exist. You're seeing this error because you have DEBUG = True in your Django settings file. Change that to False, and Django will display a standard 404 page. What am I doing wrong? What am I missing? Thank you! -

Can you use .filter and .get in the same query for Django?
I have a database where data is organized by a number that is unique, and a name that isn't unique. for example: NumCOL: NameCOL: 1 Jay 2 Joel 3 Joey 4 Joel Could I use a filter and get statement to grab names where the number is equal to a certain number? Let's say I have a form that lets a user pick a number from the database and the user picks the number 2. num = request.POST.get('FormNumber') #num = 2 name = Database.objects.filter(NumCOL=num).get('NameCOL') return HttpResponse(name) Can something like this be done? I want to grab the name wherever the user selects based on their number. Based on the code I should get a response Joel. Thanks for your help!
