Web Dev Topics.

Hi Django devs.

This is probably different from what y'all are used to, but I need your help.

I write about Django and I am looking to increase my list of Django blog posts.

Now, I am looking for blog topics that an intermediate or experienced Web developer would be interested in.

Any ideas on topics?

Am I job-ready as a developer?

First of all, little background about me. Actually I'm a computer engineering graduate, I didn't pay much attention to code during my college period however I was decent in C and C++ , got straight A's. I didn't bother learning any frameworks which would have been useful in landing a job. After graduation, I worked in Infosys as an implementation officer( I had to install software on clients' computers and teach them how to use it .) So basically there was no coding involved. And the wage was way less than the developers. So I thought I would join MBA (btw I joined MBA because I got a full scholarship )and in the meantime, I would learn some framework and land a job. So I quit my job and joined MBA.

I picked up Django and I have built three simple projects till now. they are:

1. **Portfolio website:**

what I learned:

* MVT architecture

**2. Todo app:**

So basically I followed Dennis ivy's tutorial for this. What I learned:

* CRUD operation
* Class based views
* Specific user-based data and view
* Integrated with Postgres database
* Hosted on Heroku

**3. Blog website**

What I learned:

* How to handle static files and media files
* jinja2
* Implemented all

Help with error in Jupyter Notebooks

I am having an error with Jupyter Notebooks. My error is "NameError: name '_C' is not defined. I am writing a neural network to process the BCI Competition dataset. I've posted the code as a screenshot here.

I opened Jupyter through the Anaconda command prompt. All of the packages shown as imports are installed and I have restarted the kernel. In fact, this is the second notebook to try this. When I run 'pip install torch' it states that the requirement is already satisfied and I confirmed that through the Anaconda Navigator. Torch is installed in the base root.


Can anyone help me with my error?

I created a tool to quickly view reference images using keybindings

This tool follows sort of the vim philosophy of never having to leave your keyboard. This can act as an image viewer, or as a program to quickly refer reference images, cheat sheets, notes, keybindings, etc.

​

You can specify a root directory in the config file and then navigate through the entire dir using only keys (which are also configurable in the config file)

​

This is the first time I've dedicated this much time for a project which I'll be using myself (I use it to refer all my keybindings) and also the first time I've put effort into writing proper documentation.

​

Give it a shot to see if you like it and do share your honest thoughts on areas I can improve or features you'd like to see. Let me know what you guys think!

Is there a way to hard code a data value into a model for a specific data entry?

Sorry if this question doesnt make sense but im going to do my best.

I need to create a new data field in a model. I know how to do this, I know how to make and apply a migration etc etc.

However, I need to hard-code SPECIFIC data values in this field for certain data entries. Is there a way I can do this in the model?

Ive seen how you can create a default value, but is there any way to query a specific data entry and then give it a value, and have this applied when I make the migration?

For example:
where ID = 1, name = 'bob'
where ID = 2, name = 'john'

Am I doing the Post/Redirect/Get pattern wrong?

Hello everyone! I'm currently trying to write a ModelForm but when the form validation fails and I try to refresh the page I've got this error message:

https://preview.redd.it/w600xriwxjt91.png?width=414&format=png&auto=webp&s=1e1b29889419119f786a33e12546e99d3dd57fd5

I followed a couple of tutorials and this is my current view:

def index(request):
if request.method == 'POST':
form = PostForm(request.POST, label_suffix='')
if form.is_valid():
form.save()
return redirect('home')
else:
form = PostForm(label_suffix='')

return render(request, 'post/index.html', {'form': form})

And this is my form:

class PostForm(ModelForm):
class Meta:
model = Post
fields = ['name']

Does the Jupyter API allow using Jupyter from the CL?

Can you actually use Jupyter functionalities from the command line like executing or editing and re-executing line 3?

Or is the API just for basics like exporting a notebook into a Python script?

Thank you
