Why is Nginx failing to load this diango/wagtail uwsgi socket?
I have created a virtual environment and installed wagtail as per these instructions. http://docs.wagtail.io/en/v1.9/getting_started/tutorial.html The server is setup to use uwsgi to connect to an existing application, so i would like to connect to the wagtail app in similar fashion (using uwsgi) The current Nginx config that handles the main traffic for the site (and passes it to a uwsgi socket) looks like this: - server { listen x.xx.xxx.xxx:80; server_name example.com www.example.com; access_log /var/customers/logs/webmaster-access.log combined; error_log /var/customers/logs/webmaster-error.log error; root /var/customers/webs/webmaster/; location / { uwsgi_pass unix:///opt/app/core.sock; include uwsgi_params; uwsgi_param UWSGI_SCHEME $scheme; uwsgi_param SERVER_SOFTWARE nginx/$nginx_version; } ... } This setup is working fine, for the existing non wagtail app. I have amended the entries above like so: server { listen x.xx.xxx.xxx:80; server_name example.com www.example.com; access_log /var/customers/logs/webmaster-access.log combined; error_log /var/customers/logs/webmaster-error.log error; root /var/customers/webs/webmaster/; location / { uwsgi_pass unix:///opt/rocker/core.sock; include uwsgi_params; uwsgi_param UWSGI_SCHEME $scheme; uwsgi_param SERVER_SOFTWARE nginx/$nginx_version; } ... } Simply changing the location of the socket to point to the wagtail app (which is in /opt/rocker/core.sock) instead of the existing socket. The Uwsgi log says everything is starting ok: *** Starting uWSGI 2.0.11.2 (64bit) on [Mon Mar 27 13:00:24 2017] *** compiled with version: 4.7.2 on 16 December 2015 01:49:08 os: Linux-3.2.0-4-amd64 #1 … -
Linking Django project to existing MySQL database in EC2 instance
So I've created an android app who's backend is stored in a AWS EC2 instance. I am now creating a website using Django and I would like them to share the same database, is this possible, if so how? I've been looking for the whole day and can't seem to find a solution, I've looked into deploying a Django application on AWS and it seems like I have to use Elastic Beanstalk which creates another EC2 instance and there doesn't seem to be a way to link it to my existing one. Any help would be greatly appreciated. Thank you -
CharField choice show human-readable value
I have little problem. I have models like Project and Member. Every project has members. In template I want to show user and his role in a specific project. It works but it shows me the number of role. I want to show human-readable value as "Business Analyst" e.t.c.

Maintaining static files
In my django framework I collect user input from a form and create a matplotlib image. This image is displayed after a button push in a tagged field in an html file. After each button push this image is updated, changes and is newly displayed. This works well. Now I intend to introduce a second image at a second tag, that shows up and changes after pressing a different button. The problem that I have, is that after pushing the second button, the first image disappears and after pushing the first button, the second button disappears. Here is part of the html code: <form method=post action=""> {% csrf_token %} <table> {% for field in form %} <tr> <td>{{ field.label }}</td> <td>{{ field }}</td> <td></td> </tr> {% endfor %} </table> <br> <p><input type=submit name='button1' value='Create' class="btn btn-default" ></form></p> <p> {% if result != None %} {% load static %} <img src="{% get_static_prefix %}{{ result }}" width=1000> {% endif %} </p> <form method="post" class="topright"> {{form3}} {% csrf_token %} <p><input type=submit name='button2' value='Update' class="btn btn-default" default=1 ></p> </form> <form method=post action=""> {% csrf_token %} <table> {% for field in form4 %} <tr> <td>{{ field.label }}</td> <td>{{ field }}</td> <td></td> </tr> {% endfor %} … -
Can any one give me a clear breakdown on how to integrate Elm with an existing Django app?
I have an existing Django app that currently uses vanilla js, Ajax, and Jquery. I am looking to slowly moving our front-end over to the Elm programming language and the Elm architecture but there isn't any guidance on this topic. Is there anyone out there that can provide a brief walkthrough, what to watch out for, or at least where to start. Any help would be much appreciated. Thanks -

How to pass dictionary and image through ajax to views.py in Django
Hello I'm sorry because Im new to using django. I'm currently using ajax to send files to my views.py. My dilemma is I need to pass both a dictionary and a formData containing 2 images. How do I pass this to my view, and how do I access the images and the dictionary in my views.py? pls help The concepts I know so far to transfer data are ajax and FormData.

Why are changes not getting saved to database table when editing objects using django modelform?

Failed to order a list in TreeNodeMultipleChoiceField
I have a MTTP django model with a TreeNodeMultipleChoiceField. I try to orderby the list but it doesn't work. This is how the model looks: class Region(MPTTModel): objects = RegionManager() code = models.CharField(max_length=50, unique=True) name = models.CharField(max_length=255) parent = TreeForeignKey('self', null=True, blank=True, related_name='children') def __unicode__(self): return self.name class MPTTMeta: order_insertion_by = ['name'] class Meta: ordering = ('name',) verbose_name_plural = 'Metadata Regions' And this is how the Form is: regions = TreeNodeMultipleChoiceField( required=False, queryset=Region.objects.all(), level_indicator=u'') regions.widget.attrs = {"size": 20} From the level_indicator I have removed all the underscores, so they all appear as one list. I have tried to use order_by but it doesn't return an ordered list. Any idea what I need to do? -
Change css of text and button separately with Django image upload field
I have the following field in one of my forms to allow the user to upload an image in Django: image = models.ImageField(upload_to=upload_location, null=True, blank=True) I display it as a field in my form table as follows: <form method='POST' action='' enctype='multipart/form-data'>{% csrf_token %} <div style="overflow-x:auto;"> <table class="table-form" style='table-layout:fixed;'> <tr> <th>Image</th> <td>{{ form.image }}</td> </tr> ... And here is what the HTML looks like when I inspect the element with Chrome Developer Tools: <form method='POST' action='' enctype='multipart/form-data'>{% csrf_token %} <div style="overflow-x:auto;"> <table class="table-form" style='table-layout:fixed;'> <tr> <th>Image</th> <td> <!-- IMAGE FIELD FROM DJANGO --> <input id="id_image" name="image" type="file"> </td> </tr> ... When there is no image uploaded, Django places the button alongside a piece of text saying "No file chosen". I want to be able to change this text, and the button text which says "Choose File" (shown below) independently. Currently I can only change both at once with the following in my css: #id_image { /* style */ } I want to make the "No file chosen" text size about 8px, and the "Choose File" text a bit bigger ~12px. Is this possible?...
