Sending EmailMultiAlternatives in mail_admins()
I have the below view code snippet and I would like to send email as EmailMultiAlternatives to the admins, the problem is...it doesn't render the html tags. Kindly assist with some ideas. subject = "A New Feedback" ctx = { 'name': name, 'email': email, 'message': message } message = ('ecoke/includes/email_feedback.html', ctx) if not settings.ADMINS: return mail_admins(subject, message, fail_silently=True, html_message='text/html') -
Updating wagtail page object and keeping revisions intact
HAs the title says how do I update a wagtail page object, with my own custom fields, and keep the revisions intact? Example problem: I have a Page model as follows: class MyPage(Page): paid = models.BooleanField(default=False) cost = .... .... upgrade_only_field = models.CharField(....) .... User edits these page has a bunch of revisions etcetera. They go through an "Upgrade" view which is a checkout causing them to be able to add / edit additional fields on the model. In the post of this view I am doing: self.object = form.save(commit=False) # Handle updated fields self.object.save() Now unless the object is upgraded a revision is saved that goes under moderator approval. Meaning the revision has submitted_for_moderation = True. I want to clear this on the revisions, since they no longer apply, but in my attempts this causes the previously set fields to be reset by publishing the latest revision. Meaning, after the above I'm doing: latest_revision = self.object.get_latest_revision() if latest_revision and latest_revision.submitted_for_moderation: latest_revision.publish() Am I missing something here? Why does publishing the latest revision (and hence removing moderation) cause this since it's just a ForeignKey to the page object? -
MySQL Host in Django/Nginx/Python setup - reverts to localhost
Odd issue here. This setup used to work in the past on our Django / Nginx / Python setup but is causing issues on a new machine. Very standard settings.py: DATABASES = { 'default': { 'ENGINE':'django.db.backends.mysql', 'NAME': 'dev_database', 'USER': 'dev_user', 'PASSWORD': 'devuser', 'HOST': '123.123.123.123', 'PORT': '3306', } } In the past, not a problem connecting to that HOST (123.123.123.123) however now Django reports that it's attempting to connect to the localhost (let's call that 192.0.0.1): OperationalError: (1045, "Access denied for user 'dev_user'@'192.0.0.1' (using password: YES)") We've flushed settings, wiped out .pyc files, double checked settings. -
Jenkins keeps running slave operations as root
I have a Jenkins Slave node that is used for DJango builds. Part of the procedure involves taking the most recent repository Django code from Git and then building with it. The problem is that when Jenkins runs on the slave machine, it always runs as "root". The problem is similar to this one: Jenkins runs as root instead of Jenkins but not exactly like it. It checks out repositories from Git as root If I do "ls -lart" on the workspace directory, all of the files there are owned by user: root group : root It runs everything as root (on the slave machine) - even though I have configred it to log in as a specific user. See picture of the slave node defined below. In the job (see picture), I am using the slave node only. Why is it doing this? Is some kind of caching going on? If so, how do I remove the cache? I only mention the cache because when one looks at the log file for a Jenkins run, it looks as though it is accessing some kind of cache for "root" [... snip ...] Downloading idna-2.6-py2.py3-none-any.whl (56kB) Collecting decorator (from ratelim->geocoder==1.33.0->-r requirements.txt … -
Listing tags by ManyToMany relationship in django
I'm learning Django and have gone already through various tutorials. I have created a basic blog site, but wanted to add tagging funcionality. It works - I have posts with assigned tags, but I'm struggling to list those tags in the post now. blog/models.py: class Post(models.Model): title = models.CharField(max_length=50) text = models.CharField(max_length=1000) pub_date = models.DateTimeField('date published') author = models.CharField(max_length=30) mail = models.EmailField() class Tag(models.Model): name = models.CharField(max_length=15) posts = models.ManyToManyField(Post, related_name="tags") I know I would need something like: Tag.objects.filter() but could you please guide me how to list only those related to the specific post? I was trying various combinations, but none of them worked really well... -

TypeError: cannot make memory view because object does not have the buffer - django
I am trying to make a post request to mailchimp's api. It works perfectly fine when I am doing it in my local machine but somehow when I push it into the cloud. This error appears and I thought it was because of the python version since it's the only differences between local and the cloud. In cloud it's python 2.7.6 local I am using 2.7.12 I have searched up but a few issues only talks about other lib that's causing the error. I didn't have new requirements installed at all.

Is it possible to use django generic-class based view with a database view as model?
This is my problem, i'm building a kind of clown of stackoverflow, i have questions, tags, category as models, in the welcome page of the site, i should list all the questions, i've done it using class based views on Question Model but, i don't have all the details i want.

How to implement a lesson timetable with multiple preset period times?
I want to implement a school timetable. Currently my ideas is to have a model for teachers, rooms, subjects, periods, and all of those are foreign keys of a lesson. The problem is I want to have multiple time values for periods. For example, on holidays all periods are 15 minutes shorter. Of course it would be nice if these preset time values would be a model (maybe called Times) with something like an array of pairs of start and end times. Being a model, the objects could be easily edited or created in the website. So for example one such object could be represented as ((9:00, 9:45), (10:00, 10:45), (11:00, 11:45)) and times for days with shortened lessons could be represented as ((9:00, 9:30), (9:40, 10:10), (10:20, 10:50)). As of now I have the following models: DAY_OF_THE_WEEK = ( ('1', 'Monday'), ('2', 'Tuesday'), ('3', 'Wednesday'), ) class Period(Model): weekday = models.CharField(max_length=2, choices=DAY_OF_THE_WEEK) begin_time = models.TimeField() end_time = models.TimeField() class Lesson(Model): period = models.ForeignKey(Period, on_delete=models.CASCADE) subject = ... person = ... Currently I'd have to (preferably atomically) change all the begin_ and end_times in all Periods. It would be nicer if Period was just the weekday field and an index … -

Django CSRF verfication failed

Django override UserManager to use custom user model
I'm stuck trying to override UserManager to point to my custom user model so I can implement a user registration form. I keep getting the error message: Manager isn't available; 'auth.User' has been swapped for 'users.CustomUser' So I know the manager isn't pointing to CustomUser but instead to the default User model, but I can't figure out how to change this.

Given a django assignment I'm struggling with
Basically, I'm supposed to have a login/reg page with validations (which is complete and working great.) Then have it redirect to a landing page that displays all the other users (not including the logged in user) on a table. Then it lists out all their information (see picture) with a button that allows you to poke other people and how many times they've been poked. There is also a list of people who have poked you and how many times they poked you. I really need help. How do you display the logged in users name at the top in jinja? Something like {{ user.alias }} which I can't get to work. User is the table name and alias is the field name in the db. How do you display all the records on the table? How do you display the poke history on the table? How do you add the list of people who've poked you and order it by descending order? I'm really at a loss on how to accomplish this. Any and all help would be appreciated. Am I supposed to create another table to track the pokes. I'd be willing to pay for a good answer … -
What does adding on_delete to models.py do, and what should I put in it?
FYI, the on_delete parameter in models is backwards from what it sounds like. You put "on_delete" on a Foreign Key (FK) on a model to tell django what to do if the FK entry that you are pointing to on your record is deleted. The options our shop have used the most are PROTECT, CASCADE, and SET_NULL. Here are the basic rules I have figured out: Use PROTECT when your FK is pointing to a look-up table that really shouldn't be changing and that certainly should not cause your table to change. If anyone tries to delete an entry on that look-up table, PROTECT prevents them from deleting it if it is tied to any records. It also prevents django from deleting your record just because it deleted an entry on a look-up table. This last part is critical. If someone were to delete the gender "Female" from my Gender table, I CERTAINLY would NOT want that to instantly delete any and all people I had in my Person table who had that gender. Use CASCADE when your FK is pointing to a "parent" record. So, if a Person can have many PersonEthnicity entries (he/she can be American Indian, Black, … -

Simplest Way to Run Matlab Script with Django
I would like to integrate a MATLAB script into a website I built with Django. The script accepts a few parameters and returns a table to the user. I am a novice Django user. I would like to know the simplest and fastest way to execute my MATLAB script using Django and return the results to the user. From what I have read online, it appears there are a few options: 1.) execute script using octave (free so I wouldn't need to pay for MATLAB license for the server) 2.) compile my MATLAB function as python library, write a python script with MATLAB function, and execute the script server-side using django and 3.) compile the MATLAB function as a standalone application and run that application on the server (unclear to me how exactly this would work). There are probably more options I am missing and I would appreciate recommendations on the simplest way to run a MATLAB script on a Django site. Also, the script is fast to execute and takes a 5< seconds to run on my computer, so I think I would not need to use a distributed task queue system like Celery. -

I have an index page in a django project that has (in it's header.html page) a navigation bar. I want the navigation bar to actually work ...currently when I click on 'teachers' in the nav bar I get an error. The code in header.html (which has the nav bar) </button> <div class="collapse navbar-collapse" id="navbarResponsive"> <ul class="navbar-nav ml-auto"> <li class="nav-item mx-0 mx-lg-1"> <a class="nav-link py-3 px-0 px-lg-3 rounded js-scroll-trigger" href="/teachers/teachers.html">Teachers</a> </li> </div> The link above in question is: href="/teachers/teachers.html">Teachers The file path/structure of where the teachers.html page is: C:\Users\User\Desktop\rast\teachers\templates\teachers The error: Using the URLconf defined in website.urls, Django tried these URL patterns, in this order: admin/ admin/ header/ [name='header'] [name='index'] teachers/ The current path, teachers.html, didn't match any of these. My question is - what do I need to write in the header.html page (or do I need to dos something else?) to get the nav bar button 'teachers' to go to the teachers.html page.
