How to host a Django app on Docker in an Anaconda environment?
May be a fairly simple one to the Docker-savy... I am trying to create a Django app within a Docker container, which is straightforward in-and-of-itself, but I have some complex dependencies. I want to expose a port locally for now, later on an EC2 instance probably or something. I would like to get the benefit of having conda in this environment to handle some non-python dependencies that just pip won't cover. (Specifically Rtree and some things like that...) What is the fastest way to get a Django app hosted in a Docker container IN an anaconda environment that I can quickly/easily grab packages in? -

Simple search engine in Django with custom forms
I am trying to create simple search engine for my project in Django. I could not find anything wrong with my code because there is no error message.

How to implement an API effectively in Python?
I just started working with API's and wanted some input. The web application I am creating requires getting various information from the foursquare API for multiple locations. I currently only have 1 location implemented (chipotle) and have already created a ton of variables. I hope to get information such as the store hours, address, etc. for around 10 locations total. Is there any easier way to extract information from an API in JSON format in Python/Flask? Would it be easier to create my own API? @app.route('/home', methods=['POST', 'GET']) @app.route('/', methods=['POST', 'GET']) def home(): chipotle = 'https://api.foursquare.com/v2/venues/587510d3dad26328417dd325/' cafeteria = 'https://api.foursquare.com/v2/venues/4b6b0953f964a5204cee2be3/' params = dict( client_id='', client_secret='', ) #Chipotle resp = requests.get(url=chipotle, params=params) data = resp.json() chipotle_hours = data['response']['venue']['hours']['status'] chipotle_name = data['response']['venue']['name'] chipotle_isOpen = data['response']['venue']['hours']['isOpen'] chipotle_address = data['response']['venue']['location']['address'] return render_template('index.html', chipotle_name=chipotle_name, chipotle_hours=chipotle_hours, chipotle_address=chipotle_address) -
How do I write a polymorphic join table with Django and setup it's associations?
I have four models Skill, Project, Endorsement, and Profile. There are a set list of skills that need to be able to be expanded over time and I want to create a join table that attaches to Project, Endorsement, and Profile. What is the best way to: create a new table with Django called something like SkillJoins which would have a skill_id, target_model, and target_id? and create the proper associations through Project, Endorsement, and Profile to get those lists of skills? I'm not wanting to have Project, Endorsement, and Profile inherit from another model. They are all separate concerns. -

Are there conventions for naming 'through' models in Django
Django has some very clear conventions for naming models: do so in the singular describe the object the model represents using capWords convention etc. When you are using a 'through' model, to describe a many-to-many relationship however, you are no longer describing an object, but a relationship between objects. Having googled a bit, I can't find any guidance on naming 'through' models. The example used in the django docs (Musician and Band) is named Membership. This is kind of perfect because membership exactly describes the relationship between the musician and the band. But in so many other cases there doesn't seem to be a word (or even phrase) to describe such a relationship. Take for example, the other situation used in the django docs (for a 'normal' many-to-many field) of Pizza and Topping. There doesn't seem to be a good word to describe how a pizza relates to a topping; and if I therefore needed a through field to add additional information (e.g. maybe I have a primary topping and a secondary topping) I end up with a naming difficulty. In practice there are two (maybe more, but two that I can think of) ways to procede: Call the through … -

For minimum resource usage in Django, should we gzip responses or respond uncompressed data?
Gzipping itself puts some extra load on server but this response is received by client quickly and servers gets freed quickly. But responding uncompressed data, it doesn't cost the extra load on server but it increases waiting time so client can receive all data. Between these two scenarios, which one is more optimized approach and why? -
NoReverseMatch at /basketball/ Reverse for 'detail' with arguments '('',)' not found. 1 pattern(s) tried:
I have a Django app where a user can create a Basketball object using the Basketball model and post it to a feed that is a ListView subclass. I then want other users to be able to access the details of that post by clicking the hyperlink for the object. The problem is, when I set the url for the details page to contain the variable "slug" as the object slug, it overwrites my list page with the url route "" as seen in basketball/urls.py, instead of routing to the list page it says it can't find a page with an empty slug. This does not allow me to get to the url "http://127.0.0.1:8000/basketball/" I'm working under the impression Django searched for url routes in order, so since the blank path is the first route it should be seen before the route containing the slug. Note the piece of code that is directly causing the issue is in basketball_list.html: <a href= "{% url 'basketball:detail' basketball.slug %> when this code is removed I am able to access "http://127.0.0.1:8000/basketball/" but the hyperlinks aren't there so it defeats the purpose.

Django and Firebase Auth
I'm trying to use Firebase Auth with Django, but I have a few questions. So far, I've successfully created a demo app with a login form. Upon load the page checks if firebase.auth().currentUser is set, and disables the Login button if so. If not set, then login form is editable. When user logs in, I'm calling firebase.auth().signInWithEmailAndPassword. If that succeeds, I'm calling a backend view through Ajax to verify the ID token. Now I'm trying to tie all this in with a more realistic Django app. There's some index resource at, say www.example.com, and there's the login page at www.example.com/login. When user first goes to www.example.com, the view will check if the ID token exists in the request (and verify it if yes), and then return the index resource. If not, it will redirect to login resource. Once on the login page, how would I send the user to the index page after login with the ID token in the request header? I can make ajax requests from the login page, but how do you actually send the user to another page with this authorization header in "Django style"? -

How could I modify django-tracking2 so users can opt out of tracking
I'm making a website right now and need to use django-tracking2 for analytics. Everything works but I would like to allow users to opt out and I haven't seen any options for that. I was thinking modifying the middleware portion may work but honestly, I don't know how to go about that yet since I haven't written middleware before. I tried writing a script to check a cookie called no_track and if it wasn't set, I would set it to false for default tracking and if they reject, it sets no_track to True but I had no idea where to implement it (other than the middle ware, when I tried that the server told me to contact the administrator).

I cannot use ModelForm because a message is composed of several models (q_reply_* fields will create QuickReplies() objects in my view, tags will create several Tags() etc.) I have tried passing the data specifying initial = message_values in the view when creating the form, setting the value through __init__ by getting the value in kwargs (like i did for the messages var) but it just does not want to work... I don't get any error anywhere, zero warnings and when debugging I got the confirmation that my ManyToMany where I get …
