main.js url different from chunks url on deployment while code splitting with create-react-app
I'm using React as my frontend, Django as my backend, hosting my site on Heroku and my staticfiles on AWS S3. I've followed the CRA Code Splitting docs and while it works in development, when I deployed my site, my main.js was referenced correctly through https://mywebsite.s3.amazonaws.com/static/js/main.js while my chunks are being referenced through http://mywebsite.com/static/js/2.chunk.js. I prefer not to run eject so the things I've tried included setting homepage to my s3 bucket link but this did not work. Any help would be much appreciated! -

Using Django Python I am stuck on " 'WSGIRequest' object has no attribute 'address' "error when trying to create an address form for my users

Using different databases depending on a parameter in the URL
Is there a way I can tell Django2 to use a different database (and cache/session store) depending on a parameter in the URL? Note that I have read the docs related to multiple databases en Django (https://docs.djangoproject.com/en/2.1/topics/db/multi-db/#automatic-database-routing), and that is not what I'm asking. The docs are showing an example about how to use DATABASE_ROUTERS, which is a way of choosing which database should be used programatically when using a model. What I'm asking is how can I make Django2 use different databases automatically depending on a parameter in the URL. Example: http://foo.bar/usa <-- use USA database http://foo.bar/europe <-- use Europe database -
How can I create a plugin to insert templated html within a text plugin in Django CMS
I'm fairly new to Django CMS so please forgive me if my terminology isn't right. I have a page with a placeholder within which I have added some html using the Text plugin. Within that, I would like to be able to add one or many pre-templated pieces of html. I have looked into building my own plugin but the documentation that I've been reading here only allows the plugin to be added from outside the actual text plugin page and renders the result beneath my text plugin content. What I'm looking for is to be able to build something so that it places block-level html elements within the content like the Link or Image plugins (in my case, it would be some block-level html content). How can I do this, or where can I find some more information on how this can be done? -

I'm developing a simple blog with Python and Django. On my home page, I display the 3 latest posts and then all the posts. At this point my blog is working.

Serving static files with Ngnix, Django and Docker

Running Inner Join Using Django for two tables
I have two tables QUEUE and MESSAGE. The relationship is One Queue to Many Messages. The Queue table has SEQ field which directly links to Field QUEUE in Message table. So QUEUE field is a foreign key in QUEUE table, which links to Primary key SEQ field which resides in QUEUE table. I want to get Messages in a queue with a certain status and have certain age in minutes(calculated from date_create and current time), and the result set must contain a message with the queue name So views are as follows: Queue Table Fields: SEQ, NAME Message Table Fields: MSG_NO, QUEUE, STATUS1, DATE_CREATED I need two select Messages in the Message table for last 12 hours and turn INNER JOIN Queue name to the results: I want to produce similar result using Django ORM, raw query below: SELECT m.msg_no, q.seq, To_Char(m.date_created,'yyyy/mm/dd hh24:mi:ss'), To_Char(SYSDATE-30/1440,'yyyy/mm/dd hh24:mi:ss'), q.name, Round((round(SYSDATE - m.date_created,5)*1440),1) AS msg_age FROM message m INNER JOIN queue q ON m.queue = q.seq WHERE m.date_created > To_Date(To_Char(SYSDATE,'yyyymmdd')||'050000', 'yyyymmddhh24miss') And m.date_created < (SYSDATE - 30/1440) AND m.status1 = 0 AND m.direction = 0 -
Django: How to save form fields after failing validation?
I have a form with two filefields. What I am trying to do is, if the user inputs wrong files (or incompatible files), then it will throw an error and still keep the user's uploaded file there. However, it currently clears the uploaded files. I don't think I quite understand how forms work. return render(request, 'home.html', {'form':form, 'error_msg':error_msg,} When I print field values right before render, I see all the values there, but once it renders to home.html, the form is cleared. Is it that the data is not bounded to the form somehow? -
