This app is my way of learning and exploring webapps and RESTful APIs in Django. The idea is that you create "content" that can be cross-posted to other subreddits at specified times.
https://docs.djangoproject.com/en/3.2/intro/tutorial05/#when-testing-more-is-better
For the tutorial:
"scheduler/" == "polls/"
- Frontend: Vue, need node (use nvm)
- Backend: Django
Excellent writeup structure of django
https://djangobook.com/mdj2-django-structure/
Where do we put a particular function or class?
Does the function/class return a response?
- Yes—it's a view. Put it in the views module (views.py).
- No—it's not a view, it's app logic. Put it somewhere else (somewhere_else.py).
When you have code that isn’t a view, you create a new Python module (.py file) inside your app and put related functions and classes inside the file.
Authentication
https://docs.djangoproject.com/en/3.2/topics/auth/default/
- Submit info to Django and validate database
- Make api call to reddit
- Change model. Move
userfromContenttoPost. - Create login/registration page.
- When building Post Creation page, make sure Post.override_title inherits Content.default_title if blank.
- Create Content page
- Edit
- Delete
- Create Post page
Add content:
- Title
- Post kind:
- link
- self (text)
- image
- upload file to imgur
- video
- videogif
API Requests to reddit made in the View
- User has Content
- Content is submitted through Posts
Visually, if using database input, looks like this:
u 'beggarscantbeusers' id=3
|
| c 'test 1' id=1s
| | p 'post 1' id=1
|
| c 'test 2' id=2
| | p 'post 2' id=2
| | p 'post 3' id=3
|
| c 'test 3' id=3
- Posts are made with your chosen default title. Once you create a post, you can then select that post and schedule posts to different subs individually.
-
First Screen
- When adding content, if you typed a title it won't change when you select a different type of post
- Uploads images/video to imgur
- After you have your content on there and select "Save and Continue", you are redirected to permissions screen for app permission (on reddit) if you are signed in. If you're signed out, it takes you to login page to get to permissions.
-
Next screen
- "Post as" feature
- Subreddit
- Strategy:
- Post Now "The post will go live immediately"
- Next 24 hours "Later will automatically compute the best posting time for the given subreddit, based on your selection"
- Next 7 days
- Custom Time
- Override Title "Leave blank to use the default title for this post"
- Advanced (dropdown):
- Link Flair (drop down that pulls flairs from sub)
- Send Replies to Inbox checkbox

As long as your tests are sensibly arranged, they won’t become unmanageable. Good rules-of-thumb include having:
- a separate TestClass for each model or view
- a separate test method for each set of conditions you want to test
- test method names that describe their function
How to make edits to model.
https://pytutorial.com/how-to-solve-you-are-trying-to-add-a-non-nullable-field-to-without-a-default
Steps I took to edit model:
- delete offending fields: creation_date
- makemigrations
- migrate
- add new fields to content
- makemigrations
You are trying to add the field 'created_at' with 'auto_now_add=True' to content without a default; the database needs something to populate existing rows. 1) Provide a one-off default now (will be set on all existing rows) 2) Quit, and let me add a default in models.py Select an option: 1 Please enter the default value now, as valid Python You can accept the default 'timezone.now' by pressing 'Enter' or you can provide another value. The datetime and django.utils.timezone modules are available, so you can do e.g. timezone.now Type 'exit' to exit this prompt [default: timezone.now] >>> - migrate
- makemigrations
- remove Strategy, add remaining fields to Post. changed optional datetime fields to nullable/blankable
- makemigrations
- migrate
Can delete through shell: User.objects.all().delete()
When changing systems, make sure to python3 manage.py migrate after pulling your changes.

Urlconf order notes:
Urlconf is giving me issues with how it wants to display the url in regards to order of content/post. Below are the combinations I've tried.
content.id post.id
with path
'content/<int:pk>/<int:post>/'
gives wrong
expected url when clicking on post 3: 'content/2/3'
actual: 'content/3/2', both 'content/3/2' and 'content/2/2' are same post id
post.id content.id
with path
'content/<int:pk>/<int:post>/'
gives right
post=post.id pk=content.id
with path
'content/<int:pk>/<int:post>/'
gives wrong
same as top but now urls look fine 'content/2/2' 'content/2/3'
post=content.id pk=post.id
with path
'content/<int:pk>/<int:post>/'
gives wrong url 'content/3/2' but right post content
post=content.id pk=post.id
with path
'content/<int:post>/<int:pk>/'
gives right
content.id post.id
with path
'content/<int:post>/<int:pk>/'
gives right
Process data in the View to save to Model
Where do I enter a post's schedule? Who keeps track of it? Where is the asynch task initiated and where does it finally post to reddit when the time comes?
