AngularJS and Django
new to both django and AngularJs especially. I have my data coming in from an SQL database into a table and i want to be able to sort and search it. Basic Django model and view, i think it would be the html and js that i'm stuck with. The data displays in the text with not issues, just the search and sort don't work. This is my HTML: <form> <div class="form-group"> <div class="input-group"> <div class="input-group-addon"><i class="fa fa-search"></i></div> <input type="text" class="form-control" placeholder="Search table" ng-model="searchTable"> </div> </div> </form> <table class="table table-bordered table-striped"> <thead> <tr> <td> <a href="#" ng-click="sortType = 'name'; sortReverse = !sortReverse"> Name <span ng-show="sortType == 'name' && !sortReverse" class="fa fa-caret-down"></span> <span ng-show="sortType == 'name' && sortReverse" class="fa fa-caret-up"></span> </a> </td> <td> <a href="#" ng-click="sortType = 'cost'; sortReverse = !sortReverse"> Cost <span ng-show="sortType == 'cost' && !sortReverse" class="fa fa-caret-down"></span> <span ng-show="sortType == 'cost' && sortReverse" class="fa fa-caret-up"></span> </a> </td> <td> <a href="#" ng-click="sortType = 'resource_type'; sortReverse = !sortReverse"> Resource Type <span ng-show="sortType == 'resource_type' && !sortReverse" class="fa fa-caret-down"></span> <span ng-show="sortType == 'resource_type' && sortReverse" class="fa fa-caret-up"></span> </a> </td> <td> <a href="#" ng-click="sortType = 'unit'; sortReverse = !sortReverse"> Unit <span ng-show="sortType == 'unit' && !sortReverse" class="fa fa-caret-down"></span> <span ng-show="sortType == 'unit' … -
Python Package Paths :: Finding Directories that Should Be .py Files
@Luc Saffre As I work through the Django tutorials, I like to see with my own eyes the module and class/attribute that I am inheriting via import by going to the source code at Github. However, and I have attached pics to illustrate that I (think) I went to the right place, but the files seem to be missing. For example, in Django tutorial Part 1: from django.conf.urls import include ,url So I go to Github django code and I find: django/django/conf/urls What I find is that urls is a directory with only files : init.py, i18n.py and static.py. There is no urls.py file which might have url() or include() methods. Same with models.Models. from django.db import models On django Github site I follow the directories... django/django/db/models #models is a directory, not a file with a class Model() So, what am I missing here? Looking forward to a few bread crumbs :) -

Django Python - No connection could be made because the target machine actively refused it
I have a Django python server in a virtual environment at the root of my hard drive. In the command line, when I activate the env and run python manage.py 192.168.0.47:80 it starts the server normal (no migration notice or anything), but when I load the page from the browser (using instancegaming.net locally, which is in my servers host file and has worked fine in the past locally and remotely) it loads and loads forever, and when I go to the Django server window and do Ctrl+C it updates the console and gives me the following error. Keep in mind that this env is a fresh install, with no other site packages other than Django. I've had successfully ran servers before on the same server (Windows 10 64-bit) and with the same router config. I've looked at other posts like this (Python Django-Helpdesk Error: No connection could be made because the target machine actively refused it) and a handful of others, but none of these seem to solve the problem.

Using Multiple URL Parameters to get_object in Class-Based-View
Alright, I'm fairly new to this, I've been working on my Project for a couple months now and I'd like to create URLs that accept multiple parameters to call a View. A sample URL would look like this: http://www.sample.com/builders//m// I've got this implemented successfully, by overriding get_object in my DetailView, but I'm wondering if there is a better/easier method for accomplishing this or if this is considered a bad practice. Any guidance would be appreciated. urls.py urlpatterns = [ # url(r'^$', builder_list, name='list'), # url(r'^create/$', builder_create, name='create'), # url(r'^(?P<slug>[\w-]+)/$', builder_detail, name='detail'), # url(r'^(?P<slug>[\w-]+)/edit/$', builder_update, name='update'), # url(r'^(?P<slug>[\w-]+)/delete/$', builder_delete, name='delete'), # url(r'^$', builder_list, name='sub_list'), # url(r'^m/create/$', sub_create, name='sub_create'), url(r'^(?P<builder>[\w-]+)/m/(?P<market>[\w-]+)/$', sub_detail, name='sub_detail'), # url(r'^m/(?P<slug>[\w-]+)/edit/$', sub_update, name='sub_update'), # url(r'^m/(?P<slug>[\w-]+)/delete/$', sub_delete, name='sub_delete'), ] views.py class BuilderSubDetailView(DetailView): model = BuilderSub template_name = "builders/sub_detail.html" def get_context_data(self, **kwargs): context = super(BuilderSubDetailView, self).get_context_data(**kwargs) context['now'] = timezone.now() print(context) return context def get_object(self, queryset=None): if queryset is None: queryset = self.get_queryset() # Next, try looking up by primary key. builder = self.kwargs['builder'] builder_id = Builder.objects.filter(slug=builder).first().pk market = self.kwargs['market'] market_id = Market.objects.filter(slug=market).first().pk if builder is not None and market is not None: queryset = BuilderSub.objects.filter(parent=builder_id).filter(market=market_id) # If none of those are defined, it's an error. if builder is None or market … -
Django Calculate Aggregated Totals
I am trying to build a table that will aggregate stats based on a user ID. This is the first time asking a question, so bear with me if I miss anything major.

Userena group based categorization on signup/registration
I would like to separate users into two different groups, sellers or buyers, at signup. I'm using django-userena and for the athentication and registration of users. I'm thinking of using a clone of the same signup view except with a different url tied to it. So whoever signs up at url(r'^account/signup/seller/$) linked to a seller signup button will be added to the seller group and whoever signs up at url(r'^account/signup/$) linked to a buyer signup button will be added to the buyer group. note: i will be using this grouping to grant access to view functions in another django app in my project via signals/decorators. in my accounts/form.py file, i have: class SellerSignupFormExtra(SignupForm): def save(self): new_user = super(SignupFormExtra, self).save() new_user.groups.add(Group.objects.get(name='seller')) return new_user and i added this to accounts/urls.py file url(r'^accounts/signup/seller$', 'userena_views.signup', {'signup_form': SellerSignupFormExtra}), So my question is that can i add the other users that click the buyer signup button by doing the same thing i did for sellers above or is their a better way to achieve this so that i remain DRY. -

Placeholders not rendering after upgrade to django CMS 3.4
I am trying to upgrade django CMS to version 3.4.1 from 3.3.0. I am following the upgrade instructions here. After running python manage.py migrate python manage.py cms fix-tree I boot up my dev server and navigate to one of my pages, but none of the configured placeholders render. I have verified that there are placeholders for the page, and plugins for those placeholders, in the database. Furthermore, by simply downgrading back to version 3.3.0, the placeholders and plugins all render correctly again. I am not manually rendering the placeholders, as is mentioned as a possible issue here in the upgrade notes. I am simply using the placeholder tag from cms_tags as mentioned in the documentation here. Does anyone have any idea what the issue could be? Let me know if I can provide any further information or clarification. Thanks in advance! -

Django - Get Related Key and Insert into Database
Ok, so what I'm trying to do is allow the user to add a "product" to their shop but without having to choose the shop to add it to as each user will only have ONE shop.

Stop a thread from outside parent
My Django server creates threads. The threads were introduced because I didn't want to wait till the process is complete to return the response to the request (the processes can last for hours). Now I want to stop some of those threads on user request. How can I do this? The problem I face is that the parent of the thread (the function which created it) dies out after returning the response so I'm not able to access the threads at all. I found the following answer interesting. http://stackoverflow.com/a/325528/4954434 -

django-contact-form how to use the form inside any template, without a new url?
I have installed django-contact-form, and the default url to the form is 'contact/'. But, I already have my own contact page, let's call it 'contact_us/', I wish to include the form inside 'contact_us/', using the url and view I already have for 'contact_us/'. The usual way to do that is by using {% extends 'contact_us' %}, but if I do this, and remove my original 'contact_us/' url, it gives me an ReverseError. The way I think that would be possible is if sent the ContactFormView (from django-contact-form) as context to 'contact_us/', but I think that's not possible because each view has it's own url. I want to know a way to be able to put the form easily inside of any template. There's probably a simple way to do that and I don't know. -
Django: generate div class tag value with max value
I am trying to dynamically create div class tag value for my blocks in Django. I have comments tree and decided to create limit on max value for comment block (only in template not in db). So I created next template. It works fine, but has too big line and I can't insert any spaces and new line symbol, because they break template or keep in page html-source. This is line right after comment. {% extends 'myblog/base.html' %} {% load bleach_tags %} {% block title %}{{ article.name|bleach }}{% endblock %} {% block content %} <a href="{% url 'myblog:article_detail' article.id %}"><h2>{{ article.name|bleach }}</h2></a> <div class = "post_body_detail"> {{ article.text|bleach }} </div> <div class = "comments"> {% for comment in comment_list %} <li> {# (next line is too big) div class comment level can not be bigger max value for marking purposes #} <div class = "comment{% if comment.level <= comment.MAX_COMMENT_DIV_BLOCK_DEEP %}{{comment.level}}{% else %}comment.MAX_COMMENT_DIV_BLOCK_DEEP{% endif %}"> {{ comment.text|bleach}} </div> </li> {% empty %} <li>No comments yet.</li> {% endfor %} </div> {% endblock %} -
How to organize data after using filter
Let's say I have a database table like this: NumCOL NameCol AgeCOL ColourCOL ---------------------------------------- 1 Joel 18 Blue 2 Joey 22 Red 3 Jacob 25 Green 4 Jack 27 Blue 5 Joey 21 Red In this example, NumCOL is unique and icrements by 1, NameCOL, AgeCOL & ColourCOL are not unique. I need to filter them in a way that I can grab all entries based on ColourCOL, and then grab the entries in NameCOL & AgeCOLthat are assiocated to the colour. I use this code below (where a user selects the colour blue): colour = request.POST.get('FormColour') #colour = blue name = Database.objects.filter(ColourCOL=colour).values_list('NameCOL', flat=True) Now there two names that have the colour blue, so I was thinking to use a list and append all the data into a list and just call from the list when needs be, like this: ex_list = [] tracker = 0 for x in name: age = Database.objects.filter(ColourCOL=colour, NameCOL=name).values_list('AgeCOL', flat=True) ex_list.append([name[tracker], name, age]) tracker += 1 My concern is that I won't be able to retrieve data from the list effectively (if at all) if I need to write to a PDF or display it in a table. Another solution is sorting by the NumCOL … -

django rest create model instances from angular2 frontend
