Sorting a table by clicking the table head column in Django Web
So I have a website in django. I have a table with a few colums like ServerName,IP etc.. I would like to have the header of the columns to sort the entire column. For example when I click the ServerName column it will order all the items by ABC order of the ServerName. I have heard of django-sorting-bootstrap but the guide seem complicated. Is there any easier or good guide to do that? the idea is to click with the arrow on the head and it will sort it out (It will be like a link). index.html table- <div class="container"> <br> <center><h1>DevOps Server List</h1></center> <br> <form method='GET' action=''> <input type='text' name='q' placeholder='Search Item'/> <input type='submit' value='Search' /> </form> <table class="table table-hover"> <thead> <tr> <th> Server Name </th> <th> Owner </th> <th> Project </th> <th> Description </th> <th> IP Address </th> <th> ILO </th> <th> Rack </th> <th> Status </th> <th> </th> </tr> </thead> <tbody> {% for server in posts %} <tr> <div class ="server"> <td>{{ server.ServerName }}</td> <td>{{ server.Owner }}</td> <td>{{ server.Project }}</td> <td>{{ server.Description }}</td> <td>{{ server.IP }}</td> <td>{{ server.ILO }}</td> <td>{{ server.Rack }}</td> <td>{{ server.Status }}</td> <td> <button type="button" class="btn btn-primary" data-toggle="modal" href="#delete-server-{{server.id}}" data-target="#Del{{server.id}}">Delete <span class="glyphicon glyphicon-trash" </span></button> … -
Why Django serialize returns string
I have problem with returning something browsable form serializers.serialize. My model: class BowlingGame(models.Model): Frame = models.PositiveSmallIntegerField() FrameRow = models.PositiveSmallIntegerField() Result = models.PositiveSmallIntegerField(blank=True, null=True) StrikeSpare = models.PositiveSmallIntegerField(blank=True, null=True) StrikeSpareInfo = models.CharField(max_length=1, blank=True, null=True) Time = models.DateTimeField(blank=True, null=True) GameId = models.PositiveIntegerField() StateOfGame = models.PositiveSmallIntegerField(default=1) class Meta: ordering = ('GameId',) def __str__(self): return str(self.GameId) And what I do next: >>> from django.core import serializers >>> from django.db.models import Max >>> from game.models import BowlingGame >>> a = BowlingGame.objects.all().aggregate(Max('GameId'))['GameId__max'] >>> game_frame = BowlingGame.objects.filter(GameId=a) >>> me = serializers.serialize('json', game_frame, fields=('Frame', 'FrameRow')) >>> me '[{"model": "game.bowlinggame", "pk": 2356, "fields": {"Frame": 1, "FrameRow": 1}}, {"model": "game.bowlinggame", "pk": 2357,......}}]' This seems to be string as >>> me[0] '[' and I'm looking for the first element of the queryset. I tried few more things: >>> me = serializers.serialize('json', [game_frame, ], fields=('Frame', 'FrameRow')) AttributeError: 'QuerySet' object has no attribute '_meta' My question: is it normal to return string? How I can browse the object. In fact I'm using it with AJAX but its the same. json.game_frame[0] returns '['. I need to be able to get the elements separately as normal dict or list. What is going on? -
How to add an option to view all (*) in Django?
I have a simple database with tables: Company 'CompanyID', 'int(10) unsigned', 'NO', 'PRI', NULL, 'auto_increment' 'CompanyName', 'varchar(70)', 'NO', '', NULL, '' 'Type', 'enum(\'C\',\'M\',\'S\',\'A\')', 'NO', 'MUL', NULL, '' 'Country', 'varchar(60)', 'YES', 'MUL', NULL, '' 'Website', 'varchar(60)', 'YES', '', NULL, '' 'Email', 'varchar(60)', 'YES', '', NULL, '' 'Telephone', 'double unsigned', 'YES', '', NULL, '' 'Maps_Link', 'varchar(60)', 'YES', '', NULL, '' CompanyDetails 'CompanyDetailsID', 'int(10) unsigned', 'NO', 'PRI', NULL, 'auto_increment' 'CompanyID', 'int(10) unsigned', 'NO', 'MUL', NULL, '' 'Type', 'enum(\'C\',\'M\',\'A\',\'S\')', 'NO', '', NULL, '' 'Category', 'enum(\'MEP Consultant\',\'Lighting Designer\',\'Architect\',\'Interior Designer\',\'MEP Contractor\',\'Fitout Contractor\',\'Procurement Company\',\'Developer\',\'Outdoor-Architectural\',\'Indoor-Architectural\',\'Indoor-Decorative\',\'Outdoor-Decorative\',\'Lamps\',\'Drivers\',\'Control Systems\',\'Landscaping Consultant\',\'Landscaping Contractor\',\'Other\')', 'NO', '', NULL, '' 'Comments', 'blob', 'YES', '', NULL, '' and 3 more tables (Contact, Continent, Product) I have created an app CompanyBrowser. I am trying to make a simple form with drop-down menus for: Type (from Company) Category (from Company Details) Country (from Company) For each of these, I want the user to have the option to select all (*) in the drop-down menu.

django admin edit model select/prefetch_related?
I have a Django website, with model Event, lets say: class Event(models.Model): home = models.ForeignKey('Team', related_name='%(class)s_home') away = models.ForeignKey('Team', related_name='%(class)s_away') ... class Team(models.Model): name = models.CharField("team's name", max_length=100) Using ForeignKeys for this was a bad idea, but anyway, how to make this usable in Django Admin page? In admin edit event page, a ton of foreign keys is fetched for this: http://127.0.0.1:8000/admin/event/event/116255/ It produces tons of selects like: SELECT "event_team"."id", "event_team"."name" FROM "event_team" WHERE "event_team"."id" = 346; and page dies. I was playing with these: class EventAdmin(admin.ModelAdmin): list_display = ('id', 'home', 'away', 'date_game', 'sport', 'result') search_fields = ['home__name', 'away__name'] list_select_related = ( 'home', 'away', 'league', 'sport', ... ) def get_queryset(self, request): return super(EventAdmin, self).get_queryset(request).select_related(*self.list_select_related) admin.site.register(Event, EventAdmin) But no luck. -

How to send back the tokens to android using Firebase Auth
I am developing an Android app which uses Firebase and my own server running Django. What I intend to do is, I want to first authenticate the user using android app to the django server which then generates the custom tokens as specified in firebase docs. Then I want to send the generated custom token back to the android. My question is how to send that custom token back to android? I tried to send as JSON object. But it says JWT are not JSON serializable. I passed the username and password from android app as json object and authenticated with my django server. Here is my minimal Django code: import firebase_admin from firebase_admin import credentials from firebase_admin import auth cred = credentials.Certificate("firebase-admin.json") default_app = firebase_admin.initialize_app(cred) def validateuser(request): json_data=json.loads(request.body.decode('utf-8')) try: // I verify the username and password and extract the uid uid = 'some-uid' custom_token = auth.create_custom_token(uid) result={'TAG_SUCCESS': 1, 'CUSTOM_TOKEN': custom_token } except: result={'TAG_SUCCESS': 0, 'CUSTOM_TOKEN': '0'} return HttpResponse(json.dumps(result), content_type='application/json') But it says the custom token is not JSON serializable. Is it not the way to do like this? How do I send the custom token back to the android app? And this is the error: uid: 78b30d23-6238-4634-b2e4-73cc1f0f7486 custom_token: b'eyJraWQiOiAiZmFlNzA2MzZiY2UwZTk0Y2Y5YTM2OWRlNzc4ZDZlYWQ5NGMwM2MzYiIsICJhbGciOiAiUlMyNTYiLCAidHlwIjogIkpXVCJ9.eyJpc3MiOiAiZmlyZWJhc2UtYWRtaW5zZGstOXBtbjVAYnVzdHJhY2tlci0xZDE3OS5pYW0uZ3NlcnZpY2VhY2NvdW50LmNvbSIsICJ1aWQiOiAiNzhiMzBkMjMtNjIzOC00NjM0LWIyZTQtNzNjYzFmMGY3NDg2IiwgImF1ZCI6ICJodHRwczovL2lkZW50aXR5dG9vbGtpdC5nb29nbGVhcGlzLmNvbS9nb29nbGUuaWRlbnRpdHkuaWRlbnRpdHl0b29sa2l0LnYxLklkZW50aXR5VG9vbGtpdCIsICJleHAiOiAxNTA4MDc2OTA4LCAiaWF0IjogMTUwODA3MzMwOCwgInN1YiI6ICJmaXJlYmFzZS1hZG1pbnNkay05cG1uNUBidXN0cmFja2VyLTFkMTc5LmlhbS5nc2VydmljZWFjY291bnQuY29tIn0=.jgexW_xR5FeZvuO5TPWO8EOBnRJ28ut9OR_OxeajE1_o4ns4fwd2pMXlK2GkM464P5Vi-IxheG-IIJcANxGSDeZgvgpkLfKkHMZeSaraqfEQGq6N7ipuD8o1T7zd5qm79twmFbrQZRB1y7g1-zcjL69x8KFsThWOTmo0TYj5l3zf8_2Cxbw2SGefMWkCwL0d1yQjcUqVyuSAP3-Sg8KrrqCcG4cjNOXKeWxwbUQO7DobOQlT5TfRApwWk8Td6uPjD7d6jqMo-HPKOis0vRoXMBzflZKj36-hIOFkygZNbDWLTsQzbb3HZg8dBabA5GTy--iQi038TRMIm2W0irr0ng==' … -
django - TemplateDoesNotExist error
I am working through this Getting started with Django Rest Framework by Building a Simple Product Inventory Manager tutorial. At the end the tutorial, it says that I "should now be able to run your server and start playing with diffrent API endpoints". However, when I run the server, all I'm getting is a TemplateDoesNotExist error. At no point in the tutorial does it mention creating templates (and this is eventually going to connect to an Angular 2 frontend, as shown in this tutorial), so I'm confused at to whether this is an error in my code, or if the tutorial left a step out. I do not get any console errors when I run my code. serializers.py from .models import Product, Family, Location, Transaction from rest_framework import serializers class LocationSerializer(serializers.ModelSerializer): class Meta: model = Location fields = ('reference', 'title', 'description') class FamilySerializer(serializers.ModelSerializer): class Meta: model = Family fields = ('reference', 'title', 'description', 'unit', 'minQuantity') class ProductSerializer(serializers.HyperlinkedModelSerializer): class Meta: model = Product fields = ('sku', 'barcode', 'title', 'description', 'location', 'family') depth = 1 class TransactionSerializer(serializers.ModelSerializer): product = ProductSerializer() class Meta: model = Transaction fields = ('sku', 'barcode', 'product') views.py from __future__ import unicode_literals from django.shortcuts import render from rest_framework import … -

Searching a few colums in Django
So I got a a Database with a few colums. I want to add to my search the option to search not only one column like Project. I want to search a few more colums too.. so the search will look for Project or ServerName or IP and search all of the colums or a few of them. Any idea?

Django importing app models in non-app package
I have a django project with two apps, and I also want to have a scheduled job via Heroku's job scheduling tools which handles some regular database operations. In order to handle the tasks of the scheduled job, I have a separate package in my top-level django project folder. This package requires access to the models as defined in my apps. However, I cannot find out how to import the models from my apps. The structure is as follows: myproject | | myproject | | __init__.py | | ... | myapp1 | | __init__.py | | models.py | | ... | myapp2 | | __init__.py | | models.py | | ... | customjobmodule | | __init__.py | | ... | ... I have tried several ways of importing using sys.path.append() but none of them seem to work. They all say there is no module named myapp1.models import os import sys cwd = os.getcwd() sys.path.append(cwd + '/../myapp1/') from myapp1.models import Model1 ImportError: No module named myapp1.models Is there a way to do this? When searching around I have found plenty of information about using models between django apps, but not using them outside of the django framework altogether. -
Why Django Rest Framework SessionAuthentication doesn't require csrf for unauthenticated users?
I've found this in Django Rest Framework docs: CSRF validation in REST framework works slightly differently to standard Django due to the need to support both session and non-session based authentication to the same views. This means that only authenticated requests require CSRF tokens, and anonymous requests may be sent without CSRF tokens By default DRF uses those authentication classes: 'DEFAULT_AUTHENTICATION_CLASSES'= ( 'rest_framework.authentication.SessionAuthentication', 'rest_framework.authentication.BasicAuthentication' ), What would be the problem in supporting both session and non-session based authentication while checking csrf token for unauthenticated users (using SessionAuthentication class)? -

Django: custom users
I have following users in my Django applications: 1. Normal user (UUID, email, name, address, password) 2. Remote application (UUID, name, generated random secret) 3.

Remove # and #_=_ from returning social auth url - Django

Setting up gunicorn and supervisor for django server

How to send Jinja variables to Django View

However, the issue is I cannot seem to pass in a jinja variable in AJAX. Am I missing something in my AJAX statement? If not, what would be an ideal solution?

Django - having more than one foreignkey in the same model
models.py class City(models.Model): id = models.IntegerField(primary_key=True) name = models.CharField(max_length=35) countrycode = models.CharField(max_length=3) district = models.CharField(max_length=200) population = models.IntegerField(default='0') class Country(models.Model): code = models.CharField(primary_key=True, max_length=3) name = models.CharField(max_length=52) continent = models.CharField(max_length=50) region = models.CharField(max_length=26) surfacearea = models.FloatField() indepyear = models.SmallIntegerField(blank=True, null=True) population = models.IntegerField() lifeexpectancy = models.FloatField(blank=True, null=True) gnp = models.FloatField(blank=True, null=True) gnpold = models.FloatField(blank=True, null=True) localname = models.CharField(max_length=45) governmentform = models.CharField(max_length=45) headofstate = models.CharField(max_length=60, blank=True, null=True) capital = models.IntegerField(blank=True, null=True) code2 = models.CharField(max_length=2) Question 1 In the above mentioned models how can i relate code in the Country.code to City.countrycode, i am not able to do so because Country model is declared after the City model. Question 2 And how to link the Country.capital in the Country model which is a integer that relates to City.name. Note I am converting a .sql file with InnoDB Engine to Postgresql. -

Replacing Uploaded Django File
I'm want to replace a loaded file with a different file. My model looks like this and the document I change is doc. class GeneratedDocument (models.Model): survey = models.ForeignKey(Survey) document = models.ForeignKey( Document, blank=True, null = True) doc = models.FileField( upload_to = 'generated_docs/' ) my_state_field = StateField() objects = WorkflowObjectManager() def __unicode__(self): return u'%s | %s | %s' % (self.survey.organisation, self.document.name, self.doc) I user a ModelForm to load that initially and all works fine. When I am trying to replace doc I'm using: g = GeneratedDocument.objects.get(id=int(request.POST['g_id'])) g.doc = request.FILES['doc'] g.save() It is saving the file into the right place, ie media/generated_docs/filename BUT within the model it is only saving generated_docs/filename whereas with the original load is it saving a full URL (from http://). How do I get the file uploaded to the correct media directory and save that destination within my model? Thanks for the help -
Disable form field Django inlineformset_factory
Probably an easy one I am trying to disable (i.e. that the field is present but greyed out) the 'sub_total' field on all formset lines and use javascript to update the field with whatever values are entered into the 'price_estimate' and 'quantity' fields. I have the following models: class Requisition(models.Model): create_date = models.DateTimeField(auto_now_add=True) modified_date = models.DateTimeField(auto_now=True) description = models.CharField(max_length=128, null=True, blank=True,) total = models.DecimalField(decimal_places=2, max_digits=20, null=True) class RequisitionLine(models.Model): requisition = models.ForeignKey(Requisition) product = models.CharField(max_length=50, blank=False) quantity = models.PositiveIntegerField() price_estimate = models.DecimalField(decimal_places=2, max_digits=20) sub_total = models.DecimalField(decimal_places=2, max_digits=20, null=True) @property def get_sub_total(self): return self.quantity * self.price_estimate In my view I have Formset = inlineformset_factory(models.Requisition, models.RequisitionLine, form = forms.RequsitionForm, formset= forms.RequisitionLineForm, fields=('product', 'price_estimate', 'quantity', 'sub_total'), extra=2) In forms class RequsitionForm(forms.ModelForm): class Meta: model = models.Requisition fields = ['description'] class RequisitionLineForm(forms.BaseInlineFormSet): sub_total = forms.DecimalField(disabled=True, required=False) class Meta: model = models.RequisitionLine fields = ['product', 'quantity', 'price_estimate', 'sub_total'] In addition to the code above - I have tried to modify the sub_total field on init however, whatever I try it seems that it is ignored. Any help appreciated -
Use of database ID's in the url
Is there any reason why one should prefer to use a slug in its (public) urls instead of the database id? So, is this preferred somehow... www.example.com/comments/(?P<comment_slug>[0-9]+)/details ...to this: www.example.com/comments/(?P<comment_id>[0-9]+)/details The slug could possibly just be just a linear operation on the database id (say slug = id + secret integer), as done for example in the following: https://github.com/django-notifications/django-notifications/blob/master/notifications/utils.py
