fail to send email via django
settings.py EMAIL_USE_TLS = True EMAIL_HOST = 'smtp.exmail.qq.com' EMAIL_PORT = 465 EMAIL_HOST_USER = 'admin@gushijielong.cn' EMAIL_HOST_PASSWORD = 'p@ssword' DEFAULT_FROM_EMAIL = EMAIL_HOST_USER SERVER_EMAIL = EMAIL_HOST_USER and I execute following commands in Pycharm's Console: In[2]: from django.core.mail import send_mail In[3]: send_mail('Subject here', 'Here is the message.','admin@gushijielong.cn',['sea3@qq.com'], fail_silently=False) and nothing happened. It just stuck and if I try to put another command the console only prompts "Previous command is still running.Please wait or press Ctrl C in console to interrupt." and nothing at all. It's not the smtp server problem, neither the authorization problem. Because I success send emails via Outlook with the same configuration. -
Django Apache html template css switch button not updating
I have a problem with an Apache production server not displaying a checkbox based css switch button checked state. It is being displayed correctly in the dev server. The strange thing about it is it only affects the first check button, if I put another button in front of it it works fine. If I put it into the same div the first button is hidden. This trick allows for correct displaying of the page, but it's an ugly hack and unreliable, since I don't know what's causing the issue. Any ideas why this is happening would be appreciated. Here is an screenshot of the displayed page: Screenshot of the displayed page Here is the html template: {% load static %} <head> <link rel="stylesheet" type="text/css" href="{% static 'VoltageShow/style.css' %}" /> <script src="{% static 'VoltageShow/jquery-3.1.0.min.js' %}" type="text/javascript" ></script> <script src="{% static 'VoltageShow/moment-with-locales.min.js' %}" type="text/javascript" ></script> <script src="{% static 'VoltageShow/Chart.min.js' %}" type="text/javascript" ></script> </head> <body> <h1>Voltage Page</h1> <!-- Rounded switch --> <div> <input type="checkbox"> <-- STACKOVERFLOW COMMENT: inserting this line results in correct switching of the css checkbox below --> <span style="float:left; position:relative; left:40px; height: 30px; line-height: 32px;">Record Voltage</span> <label class="switch" style="float:left; left:80px;"> <input type="checkbox" class="switch-input" checked/> <span class="switch-label" data-on="On" data-off="Off"></span> <span … -
Pulling data from a server and updating graphs dynamically on a website using Python
How would I go about creating graphs on a webpage that displays data from a server and automatically updates on its own using Python? I am not really familiar with web programming in Python. I did some googling and frameworks such as Django, Flask and Tornado popped up. Which one should I dive deep into and what reading sources should I make use of to solve this type of problem ? Also, what are some recommended/best suited languages to use to solve problems like these? -
Remove or expire cache from Django queryset
I have a Django project that have a large amount of transactions. Much queries. When using Django querysets they get cached, if I have understood it correctly. I need to remove this cache, but have not found any information regarding it. My users would like to get the latest objects as fast as possible (60 seconds would work at least). -

DJANGO - Pass Table Name In Function
I'm trying to learn how I can pass a table variable name through a function. So for example lets say I have a model like below Bio(models.Model): name = models.CharField(max_length=200) address = models.CharField(max_length=200) country = models.CharField(max_length=200) now I want to be able to pass the table name through the function. So normally I would do a people = Bio.objects.all() for x in people: print x.name I want to be able to pass the "name" variable through the function something like this... def print_name(variable): people = Bio.objects.all() for x in everyone: print x.variable print_name(name) I'm not sure exactly what I should be looking into. Thanks. -
How to use Django URLs in React JSX
I have an existing Django project. I want to use ReactJS within this as React makes handling states really really easy. The issue I am facing is how to re-use the URL templates that are already defined in Django? Example: Home/urls.py urlpatterns=[ url(r'plot/api/(?P<plot_id>[0-9]+)?$', views.LivePlot.as_view(), name='livePlot'), ] If i use just Django i can refer to the above url by {% url 'Home:livePlot' plot_id %} where plot_id is a parameter passed by the server. i am unable to leverage the same technique when using React. Any suggestions? I have access to the plot_id within my React code. React example: render: function() { return(<div className="plot"><a href=''></a></div>); } Ideally in the above example i would like to have a method to place {% url 'Home:livePlot' plot_id %} or something similar within the href attribute of anchor tag, so that the link points to example.com/plot/{plot_id}. Right now the workaround i was using involved building the url myself. So if i place this react component in example.com/sub/sub2 i would build the url as '../../plot' + plot_id. This approach fails miserably when i place the same react component in multiple pages like example.com/sub and example.com/sub/sub2 which is exactly the use-case i have. -
Django admin custom message management in admin panel
I have an admin panel for managing some Orders and I want to be able to see simultaneously manage messages displayed to a client informing him about conditions. Currently person managing Orders has to go to another view to change this message, which is not very convenient. Is it possible to have such a view: Message option 1 Message option 2 Order id | Order price | order content 1 | 10.00 | Apples 2 | 20.00 | Oranges I don't want any inlines, just to have this bullet list or something alike to make administrator work more efficient. -
Update a Foreign Key using PUT in Django Rest Framework
I am basically a new entrant into Rest framework and relatively new to Django. I am working on an Employee Rest API and I created Employee - Department tables using below Django models. I assigned a foreign key relationship between Employee's-department ID and Department-department ID. Now I want to update the Employee table using PUT operation. But when i update Employee.dept_id, it is not updated with the new value. I understand that since its a read only field, am not able to update it.

How to open remote MySQL connection at a LAMP(Python) stack

NoReverseMatch at URL, error during template rendering, etc
I am trying to incorporate an export button into my Django admin site. Able to get the button to show in admin, but every time I click the button it breaks and I get the following error: NoReverseMatch at /admin/emarshalapp/attorney/export/ Reverse for 'app_list' with arguments '()' and keyword arguments '{'app_label': ''}' not found. 1 pattern(s) tried: ['admin/(?Pfiler|emarshalapp|auth)/$'] I am trying to follow this tutorial to do the export logic, but I obviously must be doing something wrong, just not sure what.

edit django's generated javascript files
i'm not actually sure that want i want to do is doable, so i'm asking to people with more experience in Python/Django than me: what i have is a local instance of a django web app, i don't have the django files but only the css/js generated from that (specifically, is an Reviewboard instance). I'd like to change some frontend behavior, like not giving the possibility to the users to put themself as reviewer. What i want to do is simply not to show the option in the frontend (i don't care about backend). I tried to edit some js files (only adding console.log) but seems that the code that i'm editing is never running, so i guess that django use some built method to link the files in the app. Anyone can give me a clue if what i want to do is possible (and how)? Cheers -

How can I break my html table up into chunks django python

What I would like to do is split it up by tens so the first table has 3 rows then 10 columns and so on until I have 10 tables all with equal 3 rows and 10 columns.

Image models with django-ckeditor and django-ckeditor-uploader
In a django project a client has requested a WYSIWYG editor and I went for django-ckeditor along with the uploader plugin. Everything works fine, no problem with that. In the previous implementation however, images were uploaded as Image model instances and were related with the text in the database (many-to-many relationships). In order to provide a more unified experience and a smoother transition to the new system, I am looking for ways to combine the previous and current implementations. In specific, the ideal scenario would be that the images uploaded via the CKEditor would be Image model instances and the image browser would make full use of the available Image models and their files. Is there an easier way to combine Image models and django-ckeditor or is a totally custom solution the only option? -
