Youtube 37 Video Course

Add a Post Page

Length 19:13

So my plan is to watch the video and take notes - not code but flow, bash instructions, etc. Then go back through the same video and write the code.

Summary

Create a page to add a post without using the Admin page. 3 step process 1 Create a view - AddPostView 2 Create a URL - AddPostView at end of from .views import and a path 3 Create a template - add_post.html
Add Add Post link to the navbar in base.html
Have to add to models.py so that Django knows what to do with the post button on the new form.
```
    def get_absolute_url(self):
    return reverse('home')
```
Whenever create a webpage in Django it's a three step process
- Create a template
- Create a view
- Create a URL
Create add_post.html in templates and use same format as article_details.html

In ablog/theblog/views.py import CreateView

class AddPostView(CreateView):
    model = Post
    template_name = 'add_post.html'
    # This will put all the fields from the model on the page.
    fields = '__all__'
    # Or to just include certain fields:
    fields = ('title', 'body')

In ablog/theblog/urls.py:
- from .views import ....., AddPostView
- in urlpatterns - path('add_post/', AddPostView.as_view(), name='add_post'),
In base.html set the second link (called Link which I think I deleted) to href="{% url 'add_post'%}">Add Post</a>

Then in add_post.html:

<form method="POST">
    # csrf_token is a security thing that all frameworks use.
    {% csrf_token %}
    {{ form.as_p }}
    <button class="btn btn-secondary">Post</button>

In ablog/theblog/models.py create another method under class Post that tells django what to do when you click the post button from above:

from django.urls import reverse
...
def get_absolute_url(self):
    return reverse('article-detail', args=(str(self.id)))
    # Or if you want to return to the home page:
    return reverse('home')

Change the title_tag on the add_post.html template to Create a New Blog Post
He deleted the default from the title_tag field in models.py because it's not needed anymore.
