Ubuntu 17: Can't install mysqlclient
Trying to follow a Django tutorial but I cannot install mysqlclient. The tutorial claims that I can do so with the following command: pip install mysqlclient but this generates this error: Collecting mysqlclient Using cached mysqlclient-1.3.12.tar.gz Complete output from command python setup.py egg_info: /bin/sh: 1: mysql_config: not found Traceback (most recent call last): File "<string>", line 1, in <module> File "/tmp/pip-build-rrolctwh/mysqlclient/setup.py", line 17, in <module> metadata, options = get_config() File "/tmp/pip-build-rrolctwh/mysqlclient/setup_posix.py", line 44, in get_config libs = mysql_config("libs_r") File "/tmp/pip-build-rrolctwh/mysqlclient/setup_posix.py", line 26, in mysql_config raise EnvironmentError("%s not found" % (mysql_config.path,)) OSError: mysql_config not found ---------------------------------------- Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-build-rrolctwh/mysqlclient/ I have the most up-to-date pip and virtualenv installed.

Django not installing in folder where I want
I am new to python/django/pip. I created a virtualenv and I was in the bin dir when I did a pip install django. It created the django files there which is not what I wanted. So I did pip uninstall django. Then I created a folder called web in my virtualenv root and tried pip install again. This time it said loading from cache and installed django in bin folder again. So I deleted it and tried again with --no-cache-dir. This downloaded django fresh, but I am still finding the installation in bin directory! This is driving me crazy, how can I get it to install in the web directory? Any help much appreciated. -

How can I change part of a Django REST Framework JSON response from a list to a dictionary?
More specifically, I need a nested part of my response to be a multi-item dictionary rather than a list of many single-item dictionaries. I am returning all the data I want, but I cannot figure out how to format it more sensibly without what I consider to be an extraneous list Here is the (simplified) response I am currently getting: { "uielements": [ { "home-bg": { "label_text_color": "#123456", "tag_display_text": "young" } }, { "home-speak-btn": { "label_text_color": "", "tag_display_text": null } } ] } I would like the response to be in this format: { "uielements": { "home-bg": { "label_text_color": "#123456", "tag_display_text": "young" }, "home-speak-btn": { "label_text_color": "", "tag_display_text": null } } } Here is my relevant serializer.py code: class UIElementProjectSerializer(serializers.ModelSerializer): class Meta: model = UIElement def to_representation(self, obj): result = super(UIElementProjectSerializer, self).to_representation(obj) uien = UIElementName.objects.filter(id=result['uielementname'])[0] return {uien.name: result} and my relevant views.py code: class ProjectViewSet(viewsets.ViewSet): ... @detail_route(methods=['get']) def uielements(self, request, pk=None): uielements = UIElementFilterSet(params) serializer = serializers.UIElementProjectSerializer(uielements, many=True) return Response({"uielements": serializer.data}) -

Inserting singular items into repeating grids
I am building a 2-column grid layout for a Q&A page. I'm using Django and each question is looped over. I'm trying to place an Ask Question button in the top2 class. I only want one Ask Question button, and right now there is a button for every question. My question is, how do I insert a singular item into a repeating grid like this? Is there a way for a grid layout to not take up the entire horizontal screen? .top { display: grid; grid-template-columns: 3fr 1fr; grid-gap: 10px; grid-row-gap: 30px; } <div class="top"> <div class="top1"> # Stuff here... </div> <div class="top2"> <form action="{% url 'question_ask' %}"> <button class="button3"><span>Ask question</span></button> </form> </div> </div> -

Django-autocomplete-light - how to autocomplete CharField choices?
Can't figure out how to autocomplete CharField choices. I have a field nationality where I use list of countries. Normal select looks like this: <select name="nationality" class="form-control" id="id_nationality"> <option value="" selected="">---------</option> <option value="AF">Afghanistan</option> <option value="AX">Åland Islands</option> <option value="AL">Albania</option> where values are shortcuts I couldn't find autocomplete view for such situation: Select2ListView returns list of values which is not sufficient.

Cannot append extra data to jquery-fileupload call
I am trying to integrate file uploading functionality to my Django app using jQuery File Upload Plugin which can be found here. Now, I am already attaching csrf token with the input tag in the template like that: <input id="fileupload" type="file" name="document" multiple style="display: none;" data-url="{% url 'upload' %}" data-form-data='{"csrfmiddlewaretoken": "{{ csrf_token }}"}'> However, later in JS file I would like to append some extra information to this form. The proposed way is to do that by using formData as shown: $("#fileupload").fileupload({ dataType: 'json', formData: {employee_id: get_selected_employee()}, done: function (e, data) { } } }); However, this new data does not get appended to formData, which is already created in the template and contains csrf_token. If I try to append the csrf token and employee_id in .fileupload call I get 403 (CSRF token missing or incorrect) even though the csrf token seems to be valid. I cannot append employee_id in the template as it's dynamically changing. Does anyone have any thoughts? -
Suppress a Static file missing ValueError
I currently have a Django site and in one particular view, an image is displayed based on user input. With WhiteNoise, Django will report a 500 error if that image doesn't exist. However I would just rather serve a broken image reference than kill the whole page. Is there a way to suppress the error in some cases? Or perhaps some views? The error looks like this: Missing staticfiles manifest entry for '291.png' I assume you'd need to use a middleware but I'm not 100% sure how. Thanks -
What is the best way to achive realtime info on my website currently using php yii framework and django-rest for api with mysql
Here i have no idea, what to exactly use to get the real-time information on the web page on my already developed application. The real-time feature will be based on online Auction feature, as a bidder bids low/high amount all the concerned user should reflect the newer price on their window immediately without refreshing the web page. Please suggest me the best way possible, my application based on: PHP 5 frontend with yii 1.1.15 framework Python django-rest framework for the rest api to fetch data from mysql database. for this i have heard about the node js, but will it be possible using only node js without using mongodb/rethinkdb angular or express js or socket.io. -
Django - Update information accessible from a view every hour
I am creating an app which fetches data from an API every time a view is loaded. As I am expecting a big user base, I fear exceeding the rate limit. I thought about scheduling the API calls every hour and storing them in an object. Which would be a convenient way of designing this, or do you have a better idea in mind of approaching this problem? Thanks in Advance -
How to add placeholder and change form field label simultaneously in django?

AWS broken pipe error when uploading files bigger than 1 MG
I am a django newbie, and I inherited a django back-end with little documentation. I am making a request to said server, which is hosted on AWS. To store the files in the request we use S3. I have found nothing on the django code that limits the size of the file uploads, and I suspect it may be AWS closing the connection because of file size. This is the code I use, and below the error I get whenever the total size of the files is over 1 MG: import requests json_dict = {'key_1':'value_1','video':video,'image':,image} requests.post('https://api.test.whatever.io/v1/register', json=dict_reg) video is a video file ('.mov','.avi','.mp4',etc) with base64 encoding, and image is an image file ('.jpg','.png') with base64 encoding.
