Using Firebase to make a simple group chat app, alongside an already existing django-react app
I have a basic project which uses django as backend and reactJS as frontend. Basically, it just shows a home page when a user logs in, and that's it. The sign up of new users is handles through the django.admin panel. Now, I want to create a group chat for my users who are currently logged in using firebase. Here's the problem since I can't really understand the workflow on how I should proceed. My basic idea is that, 1. frontend gets the username and password from backend, 2. frontend posts them to firebase 3. firebase sends a unique id token to the frontend, 4. now frontend is logged in with both django and firebase, 5. users who are logged in joins in the group chat Is there any guidelines on how I should preceed, I have read the docs but I can't really understand what I should be doing to proceed. -

Git Push Error ( Local to Remote ) in VPS Git Server?
I've written a small django site in my Mac(Sierra OS), and I wanna to put it in my new vps(digital ocean CentOS 7). I have successfully created git server there. My local django project has an local git repository，I set remote url to my centOS git server site. And everything is going well.. I push my project to the server … and finally, it is weird that when the push task has done, I enter the remote file, and found that the ‘push task’ has only push my local .git file directory to the server.. and any other project file is ignored! Even later, I added more commits, but those made no difference. I tried to create a new repo in github.com. and push my project to the github in the exactly same way, but it works well in the github platform --- all of my project files have sucessfully pushed to the github server. How could I solve the problem? -

django blog archive, index and pagination comprehensive application
Background: I am building a blog about my research group. On the publication archive page I am going to display all the publications of my mentor. Here there is a side column to show the archive index allowing users to view the publications by year. And at the bottom of the page there is a django paginator which separate the publications in to several pages with 7 publications per page. Problem: When the pagination is used, the publications is divided into a list, so the {{publication.published_time}} only contain the data in the current page rather than the whole dataset. Thus, I wrote the hard code of year information in the front end and add the url to the corresponding year. Apparently, I wish I can get the distinct year information about all publications on the basis of the existence of a paginator. Besides, transfer the year value directly in the URL. Code: url.py: url(r'^publications/(?P<year>[0-9]{4})/$', PublicationYearArchiveView.as_view(), name="publication_year_archive"), views.py: class PublicationYearArchiveView(YearArchiveView): queryset = Publication.objects.all() date_field = "published_time" make_object_list = True allow_future = True def listing(request): limit = 7 publication_list = Publication.objects.all().order_by('published_time').reverse() paginator = Paginator(publication_list, limit) # Show 7 publications per page page = request.GET.get('page') try: publications = paginator.page(page) except PageNotAnInteger: # If … -

How do I handle migrations as a Django package maintainer?
I have been writing a new Django package that will be pip-installable. I've been stuck for awhile because I'm unsure how to make migrations for my particular package so to allow for the normal workflow of an install to be: pip install my package add my package to your "INSTALLED_APPS" run python manage.py migrate Currently, my package looks like this: package_root/ dist/ actual_package/ __init__.py models.py setup.py The problem I am facing is that when I package the app and install it using pip install dist/... and then add it to my example apps "INSTALLED_APPS", running python manage.py migrate does not create any tables for the models in actual_package/models.py and hence I (from a users perspective) need to then run python manage.py makemigrations actual_package first, which is not ideal. Any ideas on how to have the migrations already sorted before a user installs would be excellent. -

Best way of combining Django template tags and javascript compression for security
I am currently programming a website that uses Django as its server backend. The website allows users with different levels of privilege to log in. According to the privilege each user has, he should be able to see different elements of the HTML and Javascript of the webpage (ie: administrators can see the full website, managers can see less elements, normal users even less, etc). The easiest way to do this would probably be to just feed every user the same website and send them a variable telling the browser which parts of the site to show and which to hide but I don't like that solution since a savvy user could easily "hack" that variable and have access to information he shouldn't have. So, in order to keep the website easy to mantain by having a single version but keep a bit of security between the different levels of privilege, I just use the Django template tags: {% if administator %} ... { % endif %} This works perfectly fine with HTML. However if I want to do the same with Javascript, I am unable to automatically compress Javascript using Yuglify or similar libraries since they aren't able to … -

Using sox to trim a sound file within Django form class
I'm trying to build an application which allows users to edit their uploaded sound files. So far the user is able to retrieve their sounds and display as waveform with the wavesurfer js library. The idea is to grab the start and end points on the wavesurfer region selected, and pass those values to the form class (where sox will trim the file) using an updateview. I pip installed pysox and installed sox in my virtual env. This is what I have so far with my urls.py: url(r'^update_sound/(?P<pk>[\w-]+)$', UpdateSound.as_view(), name='update_sound'), my forms.py: import sox class UpdateSound(forms.ModelForm): def trim_sound(self): file = self.cleaned_data.get('sound', False) tfm = sox.Transformer(file) tfm.trim(0,0.3) class Meta: model = Sounds fields = [ 'sound', ] And the update view class UpdateSound(UpdateView): model = Sounds form_class = UpdateSound template_name= 'sound_detail.html' My main question is, 1.Is this a good way of going about editing sound files and 2. What should I add to my form class to make this work? I've looked at the sox docs and still not entirely clear on what to do. Should I be passing the sound file as an argument to the transformer? Any help is much appreciated. -

Figuring out why django can't find scripts, stylesheets, and plug-ins for my template right now
I inherited a project and I've been trying to get the file structure correct on my local machine but I haven't been able to figure it out. My django project is called gtr_site. On the home page html file, which is located in a .../templates/gtr_site/home.html path, I am trying to load scripts and stylesheets from a folder called "vendor" and its contents. The file within home.html to attempt to link some bootstrap code is as follows: <link href="vendor/bootstrap/css/bootstrap.min.css" rel="stylesheet"> When I first came across this, I made the assumption that i could be okay by creating a folder called "vendor" in same directory as home.html (in templates/gtr_site/), then creating the following directories and inserting the bootstrap file into the final directory. That hasn't worked. I get the following error messages for various files in the vendor folder: [19/Aug/2017 15:53:35] "GET /gtr/vendor/bootstrap/css/bootstrap.min.css/ HTTP/1.1" 404 1798 Not Found: /gtr/vendor/bootstrap/css/bootstrap.min.css/ So... my original approach of just creating a folder called "vendor" and going from there didn't work. Because of that, I'm left with the question of "where is this html file supposed to be searching for a folder called vendor? Is it able to find one?" I don't know necessarily how to answer … -
How to get attribute of a django model's foreign key object using getattr in python?

Is it possible to query x.y.random if all I have is object x and string 'y.random'? -

This is a relevant piece of code. print 'POLY START TYPE: ', type(start_poly) print 'POINT START TYPE: ', type(point_start) print 'POLY START - ', start_poly print 'POINT START - ', point_start print 'Contains point: ', start_poly.contains(point_start) print 'Intersects point: ', start_poly.intersects(point_start) And the output POLY START TYPE: <class 'django.contrib.gis.geos.polygon.Polygon'> POINT START TYPE: <class 'django.contrib.gis.geos.point.Point'> POLY START - SRID=4326;POLYGON ((13.08300018310547 45.27488643704894, 13.08300018310547 46.70973594407157, 16.57665252685547 46.70973594407157, 16.57665252685547 45.27488643704894, 13.08300018310547 45.27488643704894)) POINT START - SRID=4326;POINT (46.2259433 14.45591430000002) Contains point: False Intersects point: False I'm not sure why contains or intersects methods aren't returning True. What am I doing wrong? -
Django POST validation seeing number as string
I'm a bit confused where to go with this as I thought it would be part of Django's validation... I'm on 1.8 because I'm using an older database connection library that was last tested with 1.8 (rewriting a frontend for old data). models.py: class Order(models.Model): ~rest of class~ RequestorNumber = models.SmallIntegerField(db_column='requestor_no') class Requestor(models.Model): RequestorNumber = models.SmallIntegerField(primary_key=True, db_column="requester_no") Requestor = models.CharField(max_length=20, db_column = "requester") def __str__(self): return self.Requestor forms.py class OrderForm(forms.ModelForm): RequestorNumber = forms.ModelChoiceField(queryset=Requestor.objects.all().order_by('RequestorNumber'), label="Requestor") So this creates a correct dropdown in the template, with values as integers and text as the descriptions ex: <option value="1" selected="selected">JOHN DOE</option> When the form is submitted, the POST QueryDict has a proper entry when printing the entire request: ... 'OrderForm-RequestorNumber': ['1'] ... but this is coming in as a string (as I would expect), but the validator when doing is_valid() kicks back and the webpage gets: 'JOHN DOE' value must be an integer. Is this by design? I feel like it's trying ignore the value of the selected for the form and referring back to the object's __str__ definition as what needs to be saved. If this is dumb, i'm also all ears to figure out what a more correct method is, the only …
