Static files not found in Mezzanine
I am trying to install a new template on my Mezzanine website. My Mezzanine is on version 4.2.2 and Django on 1.9.7 . Here is what I did: With DEBUG = true I created a new app call "template_app" and loaded in settings.py: INSTALLED_APPS = ( "template_app", ... ) I created the directory structure, and copied over the default mezzanine files (base, index...) like: template_app static css img js templates base.html index.html includes footer_scripts.html I downloaded a bootstrap template and replaced the above css js img folder and index.html with the ones found in the template. (The template I used: https://startbootstrap.com/template-overviews/business-casual/ ) Then link the css and javascript in base.html: (All css) {% compress css %} <link rel="stylesheet" href="{% static "css/bootstrap.css" %}"> <link rel="stylesheet" href="{% static "css/bootstrap.min.css" %}"> <link rel="stylesheet" href="{% static "css/business-casual.css" %}"> <link rel="stylesheet" href="{% static "css/mezzanine.css" %}"> <link rel="stylesheet" href="{% static "css/bootstrap-theme.css" %}"> (All js) {% compress js %} <script src="{% static "mezzanine/js/"|add:settings.JQUERY_FILENAME %}"></script> <script src="{% static "js/bootstrap.js" %}"></script> <script src="{% static "js/bootstrap.min.js" %}"></script> <script src="{% static "js/jquery.js" %}"></script> <script src="{% static "js/bootstrap-extras.js" %}"></script> I'm not sure where I did wrong, or what I am missing.

Problems with Newlines using django on a Windows Server in France
Problem: My django app is introducing a CR before each CRLF when writing to a file a string which has been read in via render_to_string. In my template files, I used CRLFs, and the django processing app writes a file which adds a CR before each CRLF. See below for code details. However: this only happens with my app which is on my clients' Windows Server 12R2 VM which is located in France. My physical Windows 10 laptop, my ubuntu instances and my AWS Windows Server 12 instance (which I use for testing before installing on my client's machine) do not add the CRs. Caveat: For security reasons, I can only access my client's VM via remote desktop, so I need to set an appointment with the IT group in order to explore and debug the problem. And, that is a 9 hour time difference and takes his valuable time. Thus, I need to re-create this problem on my AWS instance so that I can try to debug my code. And, when I say it introduces a CR instead of CRLF, then I might be remembering it wrong -- it could be that my code introduces a LF instead of … -

How to use AWS Elastic Beanstalk Python with Nodejs?
These are the component used in my project Django, Angular and WebPack. So the problem is when deploying to Elastic Beanstalk I would like EB to able to compile Angular and SASS by using WebPack, but WebPack required NodeJS. Is there anyway I could use both Python and NodeJS in one EB Instance? Of course I could compile it on my local machine and deploy those to Live server, but I don't want to do that since I doesn't feel like the best practice. Thank for answering. -

nltk stemmer: string index out of range

Django Cache Issue During Production
I'm serving media files locally for production in a django application. I'm serving media files to a folder called media and nesting any uploaded images in a subfolder within media. This seems to be working fine. However, the cache that is in the same directory (media) as the subfolder does not receive images after they are uploaded. When I try to display images using their url, I'm given the cache url but there is no picture at the location. Any ideas as to why this is occurring? -

Using Paginator() class in function-based view versus pagination in class-based listview (Django project)
Is using Django's Paginator() class in a function slower than implementing pagination via a class-based listview (i.e. including paginate_by in the class definition), given similar-sized dataset to be paginated? I think both are the same under the hood, but I asked because I recently shifted over from a listview to a function-based view (which renders the same template), and my server response time doubled. The only thing I really changed was using the Paginator() class to handle pagination in the function-based view. I find it highly confusing. Can anyone shed light on this? -

Dictionary In Django Model
I'm struggling with how to structure my models to allow me to capture some raw information that, once the instance is saved, I will no longer care about programmatically but will still want to save for posterity. Specifically, I need to capture a variety of data-points tied to specific days of the week, but really those are only useful in calculating the information I do care about (such as total hours, overtime, etc). While I could do this all in the Form/View I do want to save the raw data as I'll want to display it later (but wont need it for calculating anything). I could create a Day model and use a many-to-one relationship, but I'd like to not have to call query to db 7+ times every time I display or process a timesheet. Any thoughts would be greatly appreciated. class Timesheet(models.Model): #Begin Stuff I Care About employee = models.CharField() company = models.CharField() week_ending = models.DateField() total_hours = models.DecimalField() regular_hours = models.DecimalField() overtime_hours = models.DecimalField() doubletime_hours = models.DecimalField() #End stuff I care about #For Each Day of Week - Stuff I Will Not Care About time_in_monday = models.TimeField() lunch_out_monday = models.TimeField() lunch_in_monday = models.TimeField() time_out_monday = models.TimeField() total_monday … -

Why is my private user to user chat showing in other user's chat profile?
I'm creating a private user to user chat, I'm facing an issue where when a user send messages with another user, this same chat appear on the chat of other users. Let's say user A contacted user B, user C can not see the messages sent between users A & B, but users A & B can see their discussion on user C's chat profile who have nothing to do with them. Question : How can I make it so it only shows the chat when it has to do with the sender and the recipient ? The chat profile is shown at the url page like so : /c/<recipient username>/ As you can see the image below, everything is correct because the url username match the sender or recipient username. As you can see on this other image, the url username has nothing to do with the send or recipient username.
